Answer:

125

Step-by-step explanation:

We're looking for a number that we can multiply three of the same number to get. For example, 25 is a perfect square, because 5*5 = 25.

You can test these all on your calculator, if you're allowed! Just take the third root of all of them, and if it's a whole number, you know you have a perfect cube.

The answer, though, is 125, because 5*5*5 = 125.

Write the equation of the line that passes through the points (-3, -3) and (8,7).
Verizon [17]

Answer:

y + 3 = 10/11(x + 3)

Step-by-step explanation:

Given the points (-3, -3) and (8, 7), we can use these coordinates to solve for the slope of the line using the formula:

m = \frac{y2 - y1}{x2 - x1}

Let (x1, y1) = (-3, -3)

(x2, y2) = (8, 7)

Substitute these values into the slope formula:

m = \frac{y2 - y1}{x2 - x1} = \frac{7 - (-3)}{8 - (-3)} = \frac{10}{11}

Thus, slope (m) = 10/11.

Next, using the slope (m) = 10/11, and one of the given points (-3, -3), we'll substitute these values into the point-slope form:

y - y1 = m(x - x1)

Let (x1, y1) = (-3, -3)

m = 10/11

y - y1 = m(x - x1)

y - (-3) = 10/11[x - (-3)]

Simplify:

y + 3 = 10/11(x + 3) this is the point-slope form.

Sin E= 0. 198.

E= 11.42°

Step-by-step explanation:

using Pythagoras theorem.

Hyp²= base² + height ².

101²= 99²+x²

x²= 101²-99²

x²=10201-9801.

x²=400

x=√400

x=20

sin E = opposite

________

adjacent.

sin E= 20

__

101.

sin E=0.198.

E= sin^-1(0.198)

E= 11.42°

How to solve -2(1-7n)-5n=34
OLEGan [10]

-2(1-7n)-5n=34

Multiply the bracket by -2

(-2)(1)=-2

(-2)(-7n)=14n

-2+14n-5n=34

-2+9n=34

Move -2 to the other side. Sign changes from -2 to +2.

-2+2+9n=34+2

9n=34+2

9n=36

Divide by 9 for both sides

9n/9=36/9

n=4

Answer: n=4

Jared made 12 3/4 cups of snack mix for a party.His guests eat 2/3 of the mix.How manysnack mix did his guest eat?
Fantom [35]

Answer:

<h3>The number of snacks did Jared's guest eat is 12\frac{1}{12}</h3>

Step-by-step explanation:

Given that Jared made 12\frac{3}{4} cups of snack mix for a party.

Let x be the cups of snacks mix made by Jared.

Therefore  x=12\frac{3}{4}

His guests eat \frac{2}{3} of the mix.

Let y be the guest eated snacks mix

Therefore y=\frac{2}{3}

<h3>To find how many snack mix did his guest eat :</h3>

Let z be the number of snacks did Jared's guest eat

Therefore z=x-y

z=12\frac{3}{4}-\frac{2}{3}

=\frac{51}{4}-\frac{2}{3}

=\frac{51(3)-2(4)}{4\times 3}

=\frac{153-8}{12}

=\frac{145}{12}

=12\frac{1}{12}

Therefore z=12\frac{1}{12}

<h3>Therefore the number of snacks did Jared's guest eat is 12\frac{1}{12}</h3>
