Answer:

suface area = 216

Step-by-step explanation:

For side 1 multipy 10 x 7 = 70

side 2: 8 x 7 = 56

side 3: 6 x 7 = 42

top and bottom: multipy 6 x 8 = 48, but since theres two no need for dividing by 2.

Than add them all to get 70 + 56 + 42 + 48 = 216

Answer: m = 4/5

Step-by-step explanation:

Use the slope formula

\(y_{2}-y_{1}/ x_{2} - x_{1}\)

Let's plug in the points:

5 - 1 / 8 - 3

4/5

So, m=4/5

Answer:

A) \(\frac{4}{5}\)

Step-by-step explanation:

Slope formula given 2 points:
\(\frac{y_{2}-y_{1}}{x_{2}-x_1}\)

Our points are (8,5) and (3,1)

Substitute:

\(\frac{1-5}{3-8} \\=\frac{-4}{-5}\)

negatives cancel out:
=\(\frac{4}{5}\)

Answer:

1. d = -6 2. n = -80

Step-by-step explanation:

If you divide 42 by -252 you get -6. And if you use your mental math you see that two negatives make a positive then you see it has to be negative and 80/4= 20 than -80/-4 = 20. Hope this helps, let me know if correct, and have a great day!!

Answer:

42d = -252 (since 42 is multiplied by d, you have to divide by 42 on both sides to get what d is)

d= -6

20 = n / (-4) (since n is being divided by -4, you have to multiply by -4 on both sides to get what n is)

n= -80

Step-by-step explanation:

to get what the variable is, you have to "undo" the operation that is being done.

Answer: 1 st and 3rd ones

Step-by-step explanation:

Yes it is linear since it's in the standard form Ax+By = C

A = 2

B = -8

C = 16

Answer:

yes it's linear.

Step-by-step explanation:

you can determine if it's linear by check if you can make the equation be :

y=mx+b

so first, you can change the equation 2x-8y=16 to 8y=2x-16

and then, you can take out the common fact 2, which would be 4y=x-8

at this stage, you can even devide the whole by 4, wich the equation would be y=1/4x-2 or

     y=1/4x+(-2) which is follow the equation y=mx+c, therefore, it is linear.

Answer:

3 Ib = 48 oz

16,000 lb = 8T

Step-by-step explanation:

so if you want to get 48 multiply 3 by 16

And if you want to get 8 divide 16,000 by 2000

Answer:

\(p(0) + p(1) = 2\)

Step-by-step explanation:

=> \(p(x) = x^3-x^2+1\)

Putting x = 0 in p(x)

=> \(p(0) = (0)^3-(0)^2+1\)

=> \(p(0) = 0-0+1\)

=> \(p(0) = 1\)

Putting x = 1 in p(x)

=> \(p(1) = (1)^3-(1)^2+1\)

=> \(p(1) = 1-1+1\)

=> \(p(1) = 1\)

So,

=> \(p(0)+p(1) = 1+ 1\)

=> \(p(0) + p(1) = 2\)

Answer: A deposit of 50$

Step-by-step explanation:

First, 9 Degrees below 0. 0-9 is -9 so this is a negative integer.

Second, deposit of 50$  so pretend your bank amount is x so x+ 50$ would be x + 50! Which is a positive integer

Finally, A weight loss of 10 pounds, x- 10 is probably a negative integer.

Hope this helps!

Answer:

30%

Step-by-step explanation:

\(\frac{3}{10}\) of the shape is shaded.

3/10 = 0.3          0.3 * 100 = 30

so 3/10 is 30% as a percentage.

Answer:

Step-by-step explanation:

the area of a cylinder is A=2πrh+2πr2

so this would be

2(pi)(1.5)(8)+2(pi)(1.5)(2)

24pi+6pi

30pi=94.25

The height of the cylinders are (r - 0.5)/5 and -5.5 + (r - 0.5)/5  respectively; where r represents the radius of cylinder B

The given parameters are:

Cylinder A

Radius = 6

Height = h - 5.5

Cylinder B

Radius = r

Height = h

The surface area of a cylinder is

S = 2πr(r + h)

So, we have:

Cylinder A

Radius = 6

Height = h - 5.5

S = 2π * 6(6 + h - 5.5)

Cylinder B

Radius = r

Height = h

S = 2πr(r + h)

Substitute S = 2πr(r + h) in S = 2π * 6(6 + h - 5.5)

2πr(r + h) = 2π * 6(6 + h - 5.5)

Divide both sides by 2π

(r + h) = 6(6 + h - 5.5)

This gives

(r + h) = 6(h + 0.5)

Expand

r + h = 6h + 0.5

Evaluate

r = 5h + 0.5

Rewrite as

h = (r - 0.5)/5

So, we have

h -5.5 = -5.5 + (r - 0.5)/5

Hence, the height of the cylinders are (r - 0.5)/5 and -5.5 + (r - 0.5)/5  respectively; where r represents the radius of cylinder B
