Find the volume of each of the following cubes. a. s = 7 kilometers b. s = 11 yards

nadya68 [22]

Answer:

Part 1) $V=343\ km^{3}$

Part 2) $V=1,331\ yd^{3}$

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=s^{3}$

where

s is the length of the cube

Part 1)

we have

$s=7\ km$

substitute in the formula

$V=7^{3}$

$V=343\ km^{3}$

Part 2)

we have

$s=11\ yd$

substitute in the formula

$V=11^{3}$

$V=1,331\ yd^{3}$

HELP PLESSE ITS MULTIPLE CHOICE

Andrew [12]

Answer:

<h2>Letter A</h2>

Step-by-step explanation:

First of all, we have to solve all the equations

First one is (4*1)-6

We have to use PEMDAS

which stands for

Parenthesis

Exponents

Multiplication

Divison

Addition

Subtraction

In (4*1)-6

You have to do 4*1 first ~ which equals 4

the next step would be 4-6 ~ which equals -2

The next equation would be (1*4)-6

First do 1*4 ~ which is 4

Next 4-6 ~ which again equals -2

Next equation is (1*6)-(4-6)

Parenthesis first, 1*6=6

4-6=-2

6-(-2)

which equals 8

Our next equation is 6-(1*4)

1*4=4

6-4~ which equals 2

Our last equation is 4*(1-6)

Parenthesis comes first, so it would be 1-6 first

which equals -5

4*(-5) would be our final step ~ which equals -20

All of our answers would be

-2 - from the top equation

-2 - from letter A

8 - from letter B

2 - from letter C

-20 - from letter D

which means Letter A is the answer.

Hope this is helpful.

The roots of the quadratic equation $ax^2+bx+c=0$ are

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$ .

Here the given quadratic equation is $5x^2-13x+7=0$ . Here $a=5,b=-13,c=7$ .

The roots are

$x=\frac{13 \pm \sqrt{13^2-4*5*7}}{2*5} \\ x=\frac{13 \pm \sqrt{29}}{10}$

How to solve this problem step by step. Make brainliest answer if its done. Please

D is halfway between A and B

so the coordinates of D are (2,2)

E is halfway between A and C so the coordinates of E are (-1,1)

now you need to find the gradient/slope of DE and BC using the formula:

$\frac{y2 - y1}{x2 - x1}$

<h3>Gradient of DE: </h3>

SUB IN COORDINATES OF D AND E

$\frac{1 - 2}{ - 1 - 2}$

therefore the gradient of DE is 1/3.

<h3>Gradient of BC:</h3>

SUB IN COORDINATES OF B AND C

 $\frac{ - 2 - 0}{ - 3 - 3}$ 

therefore the gradient of BC is -2/-6 which simplifies to 1/3.

<h3>therefore, BC and DE are parallel as they both have a gradient/slope of 1/3 and parallel lines have the same gradient</h3>
