(9,-4) you have to plugin 9 to the equation in the form of x. Then you add 5 and that would be your y value

Sarah mixes 2/3 cup of low fat milk and 1/2 cup of skim milk and the mixture has 111 calories. She knows that if she mixes one c

pickupchik [31]

The calories in a cup of low fat milk is 102 calories and the calories in a cup of milk in skim 86 calories .

<h3>What are the two simultaneous equations that can be sued to represent this question?</h3>

2/3l + 1/2s = 111

4l + 3s = 666 equation 1

l + s = 188 equation 2

Where:

l = calories in the low fat milk

s = calories in the skim milk

<h3>What is the calories in the skim milk?</h3>

Multiply equation 2 by 4

4l + 4s = 752 equation 3

Subtract equation 1 from 3

s = 86

<h3>What is the calories in the low fat milk?</h3>

Substitute for s in equation 2

l + 86 = 188

l = 188 - 86

l = 102

Find the geometric mean between 6 and 48 given the sequence (3,6,12,24,48,96)

Sedaia [141]

Answer:

16.97

Step-by-step explanation:

the geometric mean value of a set of n numbers is the nth root of the product of all n numbers.

so, here this means

$gm = \sqrt[6]{3 \times 6 \times 12 \times 24 \times 48 \times 96}$

this would be 16.97

but careful, the problem only asks for the gm between 6 and 48 of the sequence.

so, we actually only consider the subset 6, 12, 24, 48.

therefore

$gm = \sqrt[4]{6 \times 12 \times 24 \times 48}$

this is also

$gm = \sqrt[4]{3 \times 2 \times 3 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 3 \times 2 \times 2 \times 2 \times 2}$

$= \sqrt[4]{ {3}^{4} \times {2}^{10} }$

$= \sqrt[4]{ {3}^{4} \times {2}^{4} \times {2}^{4} \times {2}^{2} }$

$= 3 \times 2 \times 2 \times \sqrt[4]{ {2}^{2} }$

$= 12 \times \sqrt{2}$

so, we could specify the result as that simple expression

or calculate it

gm = 16.97

hey, the result is the same as for the complete sequence.

coincidence ? no, it is not. but that is a subject for a different question.

A gift box has a volume of 450 cubic inches. The width of the box is 4 inches less than the length. The height is twice the widt

VashaNatasha [74]

Answer:

width = 5 in

length = 5+4=9 in

height = 2(5)= 10 in

Step-by-step explanation:

A gift box has a volume of 450 cubic inches.

Let 'w' be the width of the box

The width of the box is 4 inches less than the length.

$length = w+4$

The height is twice the width.

$height = 2 \cdot width$

height = 2w

Volume of box = length times width times height

$V=(w+4)(w)(2w)$

$450=(w+4)(w)(2w)$

$450=2w^3+8w^2$

$2w^3+8w^2-450=0$

$\quad 2\left(w-5\right)\left(w^2+9w+45\right)=0$

$w-5=0$

w=5

$\quad\left(w^2+9w+45\right)=0$ , this gives two complex values

so width = 5

length = 5+4=9

height = 2(5)= 10

Answer:

$- 11a(3a + 2b) \\ = - 11 \times 3 \times a \times a + ( - 11 \times 2 \times a \times a) \\ = - 33 {a}^{2} - 22ab$

I hope it helps

have a great day
