Leila and Jo are two of the partners in a business. Leila makes $4 in profits for every $5 that Jo makes. If Jo makes $60 profit, how much profit does Leila make?
Answer:
Leila would make a profit of $48
Step-by-step explanation:
~ Knowing that there is some sort of proportion that can be formed through Leila and Jo's profit, we could form even a proportionality to compute the profit Leila makes given jo's profit of $60 ~
If is is known that Leila: Jo, 4: 5, we could form such a proportion:
4 5 ⇒ where x - Leila's profit knowing Jo's profit of $60
x 60
Now let us solve for x, through cross multiplication:
5x = 60 * 4,
5x = 240,
x = profit of $48
how do you write 2x - 2y = 8 in slope-intercept form ?
Answer:
y=x-4
Step-by-step explanation:
The general scaffold for the slope intercept form is y=mx+b, where m is the slope and b is the y intercept. You can rearrange the equation that you are given like this:
2x-2y=8
-2y=-2x+8
y=x-4
Hope this helps!
Answer:
Rearrange the equation so that it is written in slope intercept form:
y=mx+b.
2x+2y=8.
2y=−2x+8.
y=−x+4.

what is the answer of 24a-18b
Answer:
6(4a−3b)
Step-by-step explanation:
You have to factor out this expression, so i would recommend the UMBRELLA method.
Answer:
6(4a-3b)
Step-by-step explanation:
This is the answer because
find what number is divisible by both 24 and 18. The answer there is 6So then you write an equation that would equal 24a-18bTherefore since 24a is part one of the equation you would do what times 6 equals 24a. 6 times 4a=24aSo place four a in the parenthesis. Then find out what times 6 = -18bThe answer to that is -3b because a negative times a positive is always positive. So your final answer is 6(4a-3b)If the point (a,1) lies on the line y = 3x - 5, what is the value of a?
Answer:
a = 2
Step-by-step explanation:
Note that a point uses (x , y).
y = 1
x = a
Plug in 1 for y in the equation, and a for x:
y = 3x - 5
1 = 3a - 5
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First add 5 to both sides:
1 (+5) = 3a - 5 (+5)
1 + 5 = 3a
6 = 3a
Next, divide 3 from both sides:
(6)/3 = (3a)/3
a = 6/3
a = 2
2 is your value for a.

Mary's dog weighs 185 pounds. Her dog needs to lose between 9 and 15 pounds. Between what two percentages, rounded to the nearest whole numbers, should Mary's dog lose weight with respect to its current weight of 185 pounds. Select your answers from the drop-down lists.
Answer:
5-8% of the weight
Step-by-step explanation:
The dog needs to lose a weight within the values 9-15 pounds
To answer this question, what we just need to do is to know the percentage of 185 pounds that is 9 and the percentage of 185 pounds that is 15
The percentage decrease can be calculated using the formula;
(difference)/old value * 100%
For the 9 pound loss, we have ;
9/185 * 100% = 4.86 which is approximately 5%
For the 15 pound loss, we have;
15/185 * 100% = 8.11% which is approximately 8%
Thus, the dog is losing between 5-8% of its weight
On the blueprint of a house, 27 millimeters represents 6 meters. The actual length of the living room is 9 meters.
Answer:
40.5 mm
Step-by-step explanation:
Use a proportion to find the blueprint's length of the living room.
27 mm is to 6 m as x is to 9 m
27/6 = x/9
6x = 27 * 9
6x = 243
x = 40.5
Answer: 40.5 mm

Mark has invested $300 at age 16 into a money market account earning 6%. How many times will Mark's investment double before age 52? What will his investment be worth? What would Mark's investment be if he had invested at age 28?
Answer:
A.3times
B.$1214.68
Step-by-step Explanation
A
Using compound interest formula
A=P(1+I)^n
A is the amount
P is the principal=$300
I is the interest=0.06
n is the time ( between 52 and 16years)=36years
A=300(1+0.06)^36
A=$2444.175
Which means 300 would have become
$2444.175 which is 8 folds.
That means it would have doubled 3times(2×2×2) at age of 52.
B. The time would change to (52-28)=24
Using compound interest formula
A=300(1+0.06)^24
A=$1214.68
Therefore his investment would have been $1214.68.

Answer: x=44°
explanation: because the angles in a triangle add up to 180° and since the latter or whatever goes straight up it is 90° and the other angle is 46° so 180=90+46+x.
Subtract 90 from both sides of the = and it becomes 90=46+x.
Then you subtract 46 on both sides and you get 44=x

Which statement about the angle measure is true
Answer:
D
Step-by-step explanation:
each angle of the triangle is 95° and the second angle has to be in alphabetical order
The true statement is ∠BAC + ∠ABC = 95°
What is an angle?An angle is a figure formed by two rays or lines that share a common endpoint, called the vertex.
Angles can lie in a plane or be formed by the intersection of two planes or two curves. A reflex angle is an angle that is greater than 180 degrees but less than 360 degrees.
Given is a figure, we need to find the correct answer from the option,
We know that,
The sum of two opposite interior angles of a triangle is equal to the measurement of the exterior angle.
Therefore,
∠BAC + ∠ABC = ∠ACD
∠BAC + ∠ABC = 95°
Hence, the true statement is ∠BAC + ∠ABC = 95°

Answer:
True.
Step-by-step explanation:
To find out if the statement is true, just plug in 8 each time you see x.
3(8)+ 4 = 28
5(8) - 12 = 28
This proves the statement is true, x = 8.

Find the circumferences of the two circles. Circle A has a radius of 21 meters and Circle B has a radius of 28 meters. Use pencil and paper. Is the relationship between the radius of a circle and the distance around the circle the same for all circles? Explain.
Answer:
1.) Circumference of circle A = 131.95 metre
2.) Circumference of circle B = 175.93 metre
3.) Yes. Radius is proportional to the circumference.
Step-by-step explanation: Given that Circle A has a radius of 21 meters and Circle B has a radius of 28 meters
Circumference of a circle = 2πr
For circle A
Radius r = 21
Circumference = 2 × 3.143 × 21
Circumference = 131.95 metre
For circle B
Circumference = 2 × 3.143 × 28
Circumference = 175.93 metre
Is the relationship between the radius of a circle and the distance around the circle the same for all circles? YES
Because the radius of the circle is proportional to the distance around them ( circumference ) for all the circle. That is, the larger the radius, the larger the circumference

What type of sequence is 0,12,24,36,48 geometric or arithmetic?
Answer:
Arithmetic
Step-by-step explanation:
Since each number is 12 larger than the last, this is an arithmetic sequence. A geometric sequence is one in which each next number in the sequence is the previous one multiplied by a certain set coefficient, while in an arithmetic sequence it's a certain number added. Hope this helps!
Answer:
It is arithmetic because to get from one term to the next, you add 12, and in an arithmetic sequence, you add/subtract a common difference to get from one term to the next. Hope this helps!

A company is designing a new cylindrical water bottle. The volume of the bottle will be 187 cmcubed. The height of the water bottle is 7.3 cm. What is the radius of the water bottle? Use 3.14 for pi.
Answer:
2.86cm
Step-by-step explanation:
Step 1:
Data obtained from the question. This includes the following:
Volume (V) = 187cm3
Height (h) = 7.3cm
Pi (π) = 3.14
Radius (r) =..?
Step 2:
Determination of the radius of the cylindrical water bottle.
The radius of the cylindrical water bottle can be obtained as follow:
V = πr^2h
187 = 3.14 x r^2 x 7.3
Divide both side by 3.14 x 7.3
r^2 = 187 / (3.14 x 7.3)
Take the square root of both side
r = √[187 / (3.14 x 7.3)]
r = 2.86cm
Therefore, the radius of the cylindrical water bottle is 2.86cm
