Answer:
1) 3000 + 125m
2) 3000 + 125m = 5000
3) M= 16
4) It would take 16 months
Step-by-step explanation:
Okay so no since there are no other transaction and you already have a balance of 3000 with a monthly Fee of 125 the equation shpuld be like this.
So every month you add 125,we dont know how much months we have to pay so we can use the variable given to us in this case “M”. So your base expression should look like this,
3000 + 125m (3000 base fee that doesnt change, and 125 every month fee)
Then it asked us to put it as the final balance as 5000, so using the base expression we can do this
3000 + 125m = 5000
Now to solve it you would solve it like any other equation
5000-3000=2000
2000=125m
2000/125= 16
Okay so m = 16
M in this case stands for months so the final answer would be it would take 16 months to reach the final balance of 5000
How do relational databases work mathematically?
Answer:
A relational database stores data in a series of tables so that the data models a mathematical theory of relations. The model allows for queries based on projection, selection, and join, among other operations, and connects the data in the tables by way of keys.
Answer:
Well, I guess in a formal sense you could call relational algebra a type of logic, which puts it into the realm of ‘math’, though I don’t think most mathematicians would look at it as being a very significant area, more ‘applied logic’ than anything else.
That being said, relational algebra DOES present some formalisms in the shape of relations, tuples, normalizations, and denormalization, etc. There is also a model of sequential operations and thus the underpinnings of the ACID database concept.
Since the overwhelming primary use of RA has been as a way to structure our ideas about SQL RDBMSes there isn’t really a lot of deep theory there. I don’t think anyone has really built any other models of RA beyond an RDBMS. There have been limited non-SQL RDBMS implementations, but AFAIK none of them are really actively maintained today.

Answer:
EC=2, AD=2.4
Step-by-step explanation:
Objectives: Similar Triangles. We need to establish the scale factor of the similar triangles, and use that factor to find the missing side length.
The corresponding similar side of the left triangle is AD and AB. AB measure is 4.5 and AD measure is 1.5 so this means that AB is 3 times as long as AD. This also means that for the other sides of the left triangle as well.
AC is 3 times as long as AEBC is 3 times as long as DEUsing this information and what given in the diagram, AC measure is 3 but we need to find EC measure. We can use the addition postulate to find EC.
AE+EC=AC1+EC=3EC=2The same can be done for the triangle on the right. AC is 3 times longer than AE, so this means that AB is 3 times longer than AB using that knowledge, AD measure is 2.4
someone help me please with this algebra problem
Answer:
7 in.
Step-by-step explanation:
2L + 2W = 16
Try L = 7
2(7) + 2W = 16
14 + 2W = 16
2W = 2
W = 1
If the length is 7 in., then the width is 1 in. That is perfectly acceptable, so L = 7 in. is a good value.
Try L = 8
2(8) + 2W = 16
16 + 2W = 16
2W = 0
W = 0
A length of 8 would make a width of 0. You can't have a rectangle with 0 width, so L = 8 does not work.
When L = 9 or L = 10, the width would be negative. The width of a rectangle cannot be a negative number, so these values doe not work.
Answer: 7 in.
Please help timed question (question included in photo). I'll mark as brainiest!
Answer:
Step-by-step explanation:
This is a right triangle trig problem. Picture a right triangle. The height of the triangle is the height of the lighthouse, your distance from the base of the lighthouse is what we are solving for, and the reference angle is 2 degrees, which is the angle of inclination from where you stand to the top of this lighthouse. We have the reference angle, the side opposite the reference angle, and we are looking for the side adjacent to the reference angle. This is the tangent ratio: the side opposite the reference angle over the side adjacent to the reference angle. We know the measure of the reference angle and we know the value of the side opposite the reference angle. Filling in:

At 2:48, what is the degree measure of the smaller angle formed by the hour and minute hands of a 12 hour clock?
Answer:
The smaller angle will be "156°".
Step-by-step explanation:
According to the question,
Before 12, the minute hand at 48 minutes:
= [tex]60-48[/tex]
= [tex]12[/tex] (minutes to 12)
So,
= [tex]12 \ minutes+14 \ minutes[/tex]
= [tex]26 \ minutes[/tex]
hence,
The smaller angle will be:
= [tex]26\times 6^{\circ} \ each[/tex]
= [tex]156^{\circ}[/tex]
Answer:
The angle is 204 degree.
Step-by-step explanation:
The angle turned by minute hand in 1 minute is 6 degree
The angle turned by the hour hand in 1 hour is
For the hour hand :
The angle turned in 1 hour = 360/12 = 30degree
At 2 : 00 , the angle covered = 30 x 2 = 60 degree
In each minute the hour hand moves = 30 degrees / hour x 1 hour/60 min
= 1/2 degree
So at 2: 48 the hour hand is at 2*30 + 48 * 1/2 = 84 degrees
For the minute hand:
In each minute it turns = 6 degrees
So, at 48 minutes the minute hand is at 48 x 6 = 288 degrees
So, the angle between them is 288 - 84 = 204 degrees

Find the measure of the indicated aces and angles
Answer:
a=21
b=69
c=42
d=138
Step-by-step explanation:
c is supplementary to d (which is 138), so c=180-138= 42.
angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.
angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.
Hi I really need help with this question.So if you can help me thank you so much and if you can help me can you explain it step by step please and thank you so much your a life saver <3
Answer:
Step-by-step explanation:
I'll answer the question, but before I do, let me crab about the reliance on a diagram. You should never have to answer a question where you make assumptions about the diagram. It should state the the longest leg in one triangle = 2x - 4, and the hypotenuse in the larger triangle is 42, while in the smaller one it is x + 8\
Added to which you have to state that there is a ratio between the large triangle and the small one.
24/(2x - 4) = (x + 8)/42 Cross Multiply
24*42 = (x + 8)*(2x - 4) Remove the brackets. Combine the left
1008 = 2x^2 - 4x + 16x - 32 Combine the right and switch
2x^2 + 12x - 32 = 1008 Subtract 1008
2x^2 + 12x - 1040 = 0 Divide by 2
x^2 + 6x - 520 = 0
(x + 26)(x - 20) = 0
x = - 26 which has no meaning
x = 20 which is the answer.
2x - 4 = 2*20 - 4 = 36
x + 8 = 28
I'm not sure what you want -- the side lengths or just x.
Step-by-step explanation:
the ratio
24:2x-4=x+8:42
24/2x-4=x+8/42
24×42=(x+8)(2x-4)
1008=2x(x+8)-4(x+8)
1008=2x²+16x-4x-32
1008=2x²+12x-32
1008+32=2x²+12x
1040=2x²+12x
0=2x²+12x-1040
OR
24/2x-4=x+8/42
LCM=42(2x-4)
42(2x-4)×24/2x-4=42(2x-4)×x+8/42
42×24=(2x-4)(x+8)
1008=2x(x+8)-4(x+8)
1008=2x²+16x-4x-32
1008=2x²+12x-32
1008+32=2x²+12x
1040=2x²+12x
0=2x²+12x-1040

Answer:
0.000 008 54 = 8.54 x [tex]10^{-6}[/tex]
Step-by-step explanation:
here is the deal / the rules for scientific notation
1) the number in front of the [tex]10^{x}[/tex] has to be [tex]\geq[/tex] 1 and < 9
that rule is VERY IMPORTANT... [tex]\geq[/tex] 1 and < 9
2) if you move a decimal point to the left the exponent goes up by one
3) if you move the decimal to the right it goes down by one
examples:
314,000,000,000
starting from the right we move the decimal "11" positions to get to
3.14 (notice that I can not stop at 31.4 because that is greater than 10)
so the answer would be 3.14 x [tex]10^{11}[/tex]

The area of a wall in a house is 10.37 square metres. If a can of paint covers 3.1 square metres, how many cans of paint are needed to paint the wall?
Answer:
4 cans of paint
Step-by-step explanation:
Take the area of the wall and divide by the area that the can of pain will cover
10.37 / 3.1
3.34516129 cans
We need to round up to make sure we buy enough cans of paint
4 cans of paint
We can take area as,
Area = A
The required formula is,
→ A of wall ÷ A that paint's can will cover
Then find the no. of cans of paint that are needed to paint the wall.
Now use the formula,
→ A of wall ÷ A that paint's can will cover
→ 10.37 ÷ 3.1
→ 3.34516129032
→ 4 cans (by nearest value)
Hence, we need 4 cans to paint the wall.

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the vertices of the triangles is missing.
However, the following formula can be used to calculate distance;
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Take for instance:
[tex]A = (1,8)[/tex]
[tex]A' = (7,8)[/tex]
The distance between both is:
[tex]d = \sqrt{(1- 7)^2 + (8- 8)^2}[/tex]
[tex]d = \sqrt{(-6)^2 + 0^2}[/tex]
[tex]d = \sqrt{36 + 0}[/tex]
[tex]d = \sqrt{36}[/tex]
Take square root
[tex]d = 6[/tex]

The diameter of a wheel on harrys bicycle is 0.65m calculate the circumference of the wheel give your answer correct to 2 decimal places
Answer:
Step-by-step explanation:
[tex]C =2\pi r[/tex] and since we have to state the answer to 2 decimal places, that means that we are using the number value for π. In specific, π = 3.1415 is good enough. The other thing we note is that the formula for circumference could also be written in terms of its diameter as opposed to its radius:
C = πd. Let's use that one since we are given the diameter of the tire, not the radius.
C = (3.1415)(.65) so
C = 2.04 m
The circumference of the wheel is C = 2.04 m.
What is area of the circle?Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etcGiven ,
d = 0.65 m
π = 3.14
Let's use that one since we are given the diameter of the tire, not the radius.
Use this formula , C = πd
C = (3.1415)(.65)
so, C = 2.04 m
Therefore, the circumference of the wheel is C = 2.04 m.

The numbers 1 through 6 on singly on each face
so the probability of tossing a 1 would be;
1/6
The probability of tossing another 1 would still be same 1/6
So the probability of tossing a 1 and another 1 would be the product of the two tosses as follows;
1/6 * 1/6 = 1/36
