Gia can run 4 miles in 32 minutes. At that rate, how many miles can she run in 40 minutes
Answer:
5
Step-by-step explanation:
For these types of problems, we can use cross - multiplication.
4/32 = x/40
Notice that since 40 and 32 are both measured in minutes, we put them on the same line.
Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.

It’s x+8 at the bottom but if you solve this please give me a step by step so I know how to solve it, thank you!!♥️
Answer:
x=4.
Step-by-step explanation:
Let's solve your equation step-by-step.
5/15=x/ x+8
Step 1: Cross-multiply.
5/15=x/ x+8
5*(x+8)=x*(15)
5x+40=15x
Step 2: Subtract 15x from both sides.
5x+40−15x=15x−15x
−10x+40=0
Step 3: Subtract 40 from both sides.
−10x+40−40=0−40
−10x=−40
Step 4: Divide both sides by -10.
−10x−10=−40−10
Then your answer will be x=4.

An open box is to be made by using a piece of sheet metal with the dimensions of 4m by 2m. Determine the dimensions the box should be to maximize volume by cutting out the four corners of the material and folding up the edges to make the box. The material that is cut out is waste and cannot be used.
Answer:
Dimensions: 0.4 by 3.2 by 1.2
Step-by-step explanation:
I'm assuming here that we are cutting out squares out of each of the metal's corners:
Let x = the length of each cut-out square,
Each base (of the desired net square folded) is 4-2x, and 2-2x respectively,
Volume = x(4-2x)(2-2x)
= 4x^3 - 12x + 8x
Now we take the derivative:
[tex]\frac{d}{dx}\left[4x^3-12x^2+8x\right]\\\\= \frac{d}{dx}\left(4x^3\right)-\frac{d}{dx}\left(12x^2\right)+\frac{d}{dx}\left(8x\right)\\\\= 12x^2-24x+8[/tex]
We equate to 0 (0 for max volume), and solve using the quadratic formula:
[tex]12x^2-24x+8=0,\\\\x_{1,\:2}=\frac{-\left(-24\right)\pm \sqrt{\left(-24\right)^2-4\cdot \:12\cdot \:8}}{2\cdot \:12}\\\\= \frac{-\left(-24\right)\pm \:8\sqrt{3}}{2\cdot \:12}\\\\\mathrm{Separate\:the\:solutions}:\\\\x_1=\frac{-\left(-24\right)+8\sqrt{3}}{2\cdot \:12},\:x_2=\frac{-\left(-24\right)-8\sqrt{3}}{2\cdot \:12}\\\\x =\frac{3+\sqrt{3}}{3},\:x=\frac{3-\sqrt{3}}{3}\\\\x=1.57735\dots ,\:x=0.42264\dots[/tex]
So we approximate the side lengths to be 1.6 and 0.4 respectively. But when we plug in 1.6 for x, we get the volume as negative. Therefore x has to be 0.4.
Side lengths: 0.4, 4-2(0.4) => 3.2, 2-2(0.4) => 1.2

Is that right? Is x equal to 6?
Answer:
x=4
Step-by-step explanation:
It can't be x=6 because 15x6 is 90 and that doesn't allow for the 8x-2. The bottom half has to equal 180 because it's a straight line. So, 18x4=60. Then 8(4)-2 equals 30. 30+60=90. 90+90 equals 180.
A $300 computer has a 35% tax. What is the cost of the tax?
A) $150
B) $200
C) $80
D) $105
Answer:
D : $105
Step-by-step explanation:
I use Proportional Reasoning.
part percent
whole 100 is the formula.
We are looking for the part so we will keep that as "x"
x 35
300 100
100 x 3 is 300. So 35 x 3 is 105. Thats the answer!

point slope and slope intercept
Answer:
Step-by-step explanation:
Observe what happens to y if we move from x = 1 to x = 9: y decreases by 2. Thus, the slope of the line in question is m = rise / run = -2/8, or -1/4.
Writing the equation in point-slope form, y - k = m(x - h), we get:
y - 7 = (-1/4)(x - 1) (point-slope form)
Solving for y results in the slope-intercept form:
y = 7 - x/4 + 1, or
y = (-1/4)x + 8 (slope-intercept form)
What's -2/9 * 5/6? I'm a bit stuck.
Answer:
-2/9*5/6
As it is multiplication we can directly multiply them.
Thus we will get,
(-2*5)/(9*6)
-10/54
And now by converting into the simplest form we will get,
-5/27
And this is the final answer.

Which expression has a value of 35 when p = 7?
Answer:
B) 5p
Step-by-step explanation:
If you substitute 7 in for each equation you will see that the answers are either 7, 38, or 32, which are not 35. But when you substitute 7 in for B, 5(7), and multiply it out you get 35. I hope this helps :)
Can someone explain how this would be done, please?
A communications company is planning to launch a new satellite into orbit to improve the operation of its network. The longest distance that the satellite can send a reliable signal is 4,500 miles. The company is trying to determine the optimal height to operate the satellite so that it has maximum coverage of Earth within its range.
With the satellite directly overhead, how far above the surface of Earth does the satellite need to be so it provides the maximum coverage of its signal? Explain how you arrived at the answer.
Answer:
The satellite needs to be about 6,000 to 12,000 altitude because the higher it is the more it can connect to technology on earth

Brian rolls a fair dice 60 times.
How many times would Brian expect to roll a three?
Answer:
10 times.
Step-by-step explanation:
He rolls all the dice independently, so The expected number of 3's is 60 * (expected number of 3's in one throw).
The expected number of 3's in one throw is:
5/6 * 0 + 1/6 * 1 = 1/6
because 5/6 of the time we roll zero 3's and 1/6 of the time we roll one 3 :D
So he should expect (60 * 1/6 = 10) 3's in 60 throws.
