Answer:

384

Step-by-step explanation:

So there are 6 faces in a cube so first you need to know how big is one face then just multiply by 6 for all 6 faces. so 8*8 = 64. that means 64 is the area of one face.

then multiply that by 6 to get the total surface area.

there it is your answer 384 the 3rd option there

Answer:

Zero

Step-by-step explanation:

Any equation that is y = a number, you have a horizontal line, with a zero slope, think of HOY, H(orizontal) O=zero Y=#

Answer: slope -1; y-intercept is 13, (0,13)

Step-by-step explanation:

We rewrite the function as y = -x + 13

y = mx + b; m is the slope, b is the intercept, by comparison, we found that the slope is -1, and the y-intercept is 13.

Answer:

f(x) = -2(x-3)^2+8

Step-by-step explanation:

Using vertex form: f(x)= a(x-h)^2 +k

if the maximum is 8 then k=8

h = 3 --> the midpoint of 1 and 5

Fill in the equation:

f(x) = a(x-3)^2 +8

Using f(1) = 0 to figure out a:

0 = a(1-3)^2+8

4a =-8

a = -2

Our final equation would be[tex]f(x)=-2(x-3)^2+8[/tex]

In standard form:  [tex]f(x)=-2x+12x-10[/tex]

Answer:

use Pythagoras theorem for this question because this is a right angled triangle

Answer:

Step-by-step explanation:

since the absolute values do not apply to positive numbers because the absolute value of say 5 is still five. But the absolute value of -5 is 5.

the absolute value of 1 is 1.

so it is 1 unit above sea level

Step-by-step explanation:

The unit rate of t tacos for c dollars is t/c.

Given that, t tacos costs for c dollars.

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Here,

The unit rate = Number of tacos/Cost of t tacos

= t/c

Therefore, the unit rate of t tacos for c dollars is t/c.

Square is a rhombus. (option b)

Answer:

Leona ordered 19 boxes of pens and 5 rubber bands

Step-by-step explanation:

Let there are p pen and b rubber bands.

ATQ,

p+b = 24 ...(1)

and

10p+4b = 210 ...(2)

Multiply equation (1) by 10.

10p+10b = 240 ...(3)

Subtract equation (2) from (3).

10p+10b-(10p+4b ) = 240-210

6b = 30

b = 5

Put the value of b in equation (1).

p+5 = 24

p = 19

Hence, Leona ordered 19 boxes of pens and 5 rubber bands.
