Answer:
h=7
Step-by-step explanation:
First we need to define the formula for surface area
2(wl+hl+hw)=100
Now we can replace length with x
That makes width .5x and height x+3
2(.5x^2+x^2+3x+.5x^2+1.5x)=100
2(2x^2+4.5x)=100
2x^2+4.5x=50
2x^2+4.5x-50=0
Insert into quadratic equation (a=2x^2, b=4.5, c=-50)
x=4 or -6.25
x can't be negative so x is 4
h=x+3=7
h=7
1) A furlong is 1/8 of a mile. What part of a mile is 6 furlongs?
Answer:
6/8 of a mile,
Step-by-step explanation:
if one furlong is 1/8 of a mile, the 6 shall be 1/8 added to itself 6 times, therefore it shall be 6/8.
Answer:
3/4 of a mile
Step-by-step explanation:
1 furlong = 1/8 mile
======== ====
6 forlongs = x
cross multiply
1*x = 6 * (1/8)
x = 6/8
reduce 6/8. Divide top and bottom by 2
x = 3/4
How is 30% equivalent to 1.3?
Answer:
30% = 30/100 = 0.3
1.3 would be 130%
I hope this helps you!
30% is equivalent to 0.30 or 3/10, but not 1.3.
There seems to be an error in the statement that 30% is equivalent to 1.3. That is not correct.
To clarify, 30% is equivalent to the decimal value 0.30 or the fraction 3/10.
To convert a percentage to a decimal, we divide the percentage value by 100. In this case, 30 divided by 100 equals 0.30.
If you were looking for a value that represents a 30% increase or an amount including a 30% addition, you would multiply the original value by 1.3, not 30%. For example, if you have a value of $100 and want to increase it by 30%, you would multiply $100 by 1.3, resulting in $130.
So, 30% is equivalent to 0.30 or 3/10, but not 1.3.

Answer:
10.5% compounded quarterly will be worth more at the end of 7 years.
Step-by-step explanation:
Investment 1:
Principal=$1,000
t=7 years
n=12 months
r=9%=0.09
FV=PV(1+r/n)^nt
Where,
FV=future value
PV=present value
r=interest rate
t=time (years)
n=number of periods
FV=PV(1+r/n)^nt
=1000(1+0.09/12)^12*7
=1000(1+0.0075)^84
=1000(1.0075)^84
=1000(1.8732)
=1,873.2
FV=$1,873.2
Investment 2:
Principal=$1,000
t=7 years
r=10.5%=0.105
n=4
FV=PV(1+r/n)^nt
=1000(1+0.105/4)^4*7
=1000(1+0.02625)^28
=1000(1.02625)^28
=1000(2.0658)
=2,065.8
FV=$2,065.8
10.5% compounded quarterly will be worth more at the end of 7 years.

Find the m∠RLU. A. 20 B. 42 C. 84 D. 10
Answer:
b is the correct answer. p is 10
The value of m∠RLU = 10.
How to estimate the value of m∠RLU?Given: (5p - 8) and (2p + 22)
Simplifying both of the equation, then we get
5p - 8 = 2p + 22
Add 8 to both sides of the equation, then we get
5p - 8 + 8 = 2p + 22 + 8
simplify
5p = 2p + 30
substract 2p from both sides of the equation
5p - 2p = 2p + 30 - 2p
3p = 30
p = 30/3
p = 10.
m∠RLU = 10

the formula for a trapezoid is A= 1/2h(b1+b2) which equations are equivalent to the formula
Answer:
A=[tex]\frac{a+b}{2} (h)[/tex]
Step-by-step explanation:
Option first, option second, and option fourth are correct this expression is equivalent to the formula for a trapezoid.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
The options are:
h=2A/(b1+b2)b1=2A/h - b2b2= 2A/b1 - hb2= 2A/h - b1b1= 2A//b2 - hWe have a formula for finding the area of the trapezoid:
[tex]\rm A= \dfrac{1}{2}h(b_1+b_2)[/tex]
Make a subject h and solve for h:
[tex]\rm \dfrac{2A}{(b_1+b_2)}= h[/tex]
or
[tex]\rm h = \dfrac{2A}{(b_1+b_2)}[/tex]
[tex]\rm b_2 = \dfrac{2A}{h}- b_1[/tex]
[tex]\rm b_1 = \dfrac{2A}{h}- b_2[/tex]

What will come in the circle
I will even rate who ever answer
And give brainliest
Answer:
1st circle: 1.25
Second circle: 2
Step-by-step explanation:
We can use the cross product property here to find the value of what's in the circles.
Let's first look at the first two fractions.
[tex]\frac{x}{5} = \frac{1}{4}[/tex]
We can multiply the cross values and divide by the number that is diagonal to the variable.
[tex]5\cdot1 = 5\\5\div4 = 1.25[/tex]
So 1.25 goes in the first circle.
Now let's look at the last two circles and use the same property to find the missing value.
[tex]\frac{1}{4} = \frac{0.5}{x}\\ 4\cdot0.5 = 2\\2\div1 = 2[/tex]
So 2 goes in the second circle.

what are the four different ways to solve a quadratic equation? When would you prefer to use each method?
Answer:
4
Step-by-step explanation:
factoring , using square roots , completing the square and the quadratic formular
Answer:
See below.
Step-by-step explanation:
The four main ways to solve a quadratic equation are:
1) Factoring, 2) Completing the Square, 3) Graphing, and 4) Quadratic Formula.
Each method has it's own pros and cons.
1) Factoring. You should factor when the given equation is easily factor-able or already factored. For instance:
[tex]0=x^2-4x-12\\0=(x+7)(x-1)[/tex]
These problems are easily factored so factoring is preferred here. However, factoring will not always work.
2) Completing the Square. You complete the square if you are able to complete the perfect square trinomial with only integers. For instance:
[tex]x^2-2x-7=0\\(x^2-2x+1)-7-1=0\\(x-2)^2-8=0[/tex]
However, you wound't use completing the square if:
[tex]x^2-3x+2=0\\(x^2-3x+9/4)+2-9/4=0[/tex]
The perfect square trinomial includes fractions so you would use alternative methods here (and factoring works here!).
Despite the complexity of completing the square, if done correctly, it works every time. However, sometimes, it can be time-consuming.
3) Graphing. Graphing (if on paper) is time-consuming. You would only use graphing when you only need an approximation. Unless directed to, you probably won't need to use graphing.
However, if you have a graphing calculator, graphing the equation can allow you to check your answer. So, graphing won't get you precise answer, but it will allow you to check your answer is necessary.
4) Quadratic Formula. Use the quadratic formula if the equation isn't factor-able and completing the square is too tedious. For instance:
[tex]4.1x^2-3x-7=0\\[/tex]
This doesn't seem factor-able and completing the square will take a while. Graphing won't get the exact answer, so the quadratic formula is the only avenue left.
The quadratic method, like completing the square, will always work.
Only con is that you need to memorize the formula.

Answer: B
Step-by-step explanation:
Any inscribed quadrilateral (quadrilateral in a circle) has opposite angles that add up to 180 degrees.
So looking at he picture we can see that, (x+16) + (6x-4) = 180.
So your answer is B.
Answer:
Hey There!! The answer to this is B: angle P + angle R = 180
angle O + angle Q = 180
Here, they are only interested in R, therefore the first equation will be enough to solve for R.
angle P + angle R = 180
y + (3y + 8) = 180
We need to solve for y, so put that y value in (3y + 8) to find angle R.
y + (3y + 8) = 180
y + 3y + 8 = 180
We add the y terms: 4y + 8 = 180
Subtract 8 from both sides: 4y = 180-8 = 172
Divide both sides by 4
y = 172/4 = 43
Angle R = 3y + 8
Put y = 43 and calculate R.
R = 3(43) + 8
R = 137
Therefore, the measure of angle R is B:
