A picnic favorite is strawberry Shortcake! Each batch of strawberry
shortcake calls for 1 2/5 pounds of cake and 3/4 pound of strawberries. If
you want to make 5 batches of strawberry shortcake, how many pounds
of cake and strawberries do you need to buy?

Answers

Answer:

To make 5 batches of strawberry shortcake you'll need 7 pounds of cake and 3 3/4 pounds of strawberries for a total sum of 10 3/4 pounds.

Step-by-step explanation:

1 - Write an equation to represent the problem

For every batch, it takes 1 2/5 pounds of cake and 3/4 pounds of strawberries

therefore

[tex]Let \\\ n_c = pounds~of~cake \\\n_s = pounds~of~strawberries \\\b = number~of~batches[/tex]

[tex]n_c = 1 \frac{2}{5}b \\\n_s = \frac{3}{4}b[/tex]

For ease of math, lets convert these to decimals

[tex]n_c = 1.4b \\\n_s = 0.75b[/tex]

2 - Plug in your variables to solve for cake and strawberries

Cake

[tex]n_c = 1.4b \\\ n_c = 1.4(5)\\n_c = 7[/tex]

To make 5 batches of strawberry shortcake you will need 7 pounds of cake

Strawberry

[tex]n_s = 0.75b \\\n_s = 0.75(5) \\\n_s = 3.75[/tex]

to make 5 batches of strawberry shortcake you will need 3.75 or 3 3/4 pounds of strawberries --- Totalling in at 10.75 pounds or 10 3/4

Hope this helps :)

The population of Luis’s city in 2005 was 7400 and the population in 2010 was 9000. Let x represent the number of years since 2005. Which linear equation, in slope-intercept form, represents the population, y, at a year since 2005, x, where y is in thousands.

Answers

Answer:

The linear equation is;

y = 320x + 7400

Step-by-step explanation:

Here, we want to write a linear equation that represents the population y at a year since 2005

To write this, we need points

Initially, we have (0,7400)

Since the difference between 2005 and 2010 is 5, the second point will be (5,9000)

Mathematically, we can get the slope as follows;

m = (y2-y1)/(x2-x1) = (9000-7400)/(5-0) = 1,600/5 = 320

The equation of the line can be represented using the general form as;

y = mx + b

where m is 320 and b is unknown

So we have the equation as;

y = 320x + b

we need to get b

To get b, we can use any point

let us use the point (0,7400)

substituting this;

7400 = 320(0) + c

c = 7400

so the equation is;

y = 320x + 7400

1. [tex]\frac{x}{15}[/tex] = 0.85

2. x = 12.75

Step-by-step explanation:

First, we do 12 divided by 15, which is 0.80 (80%). The question is asking how much consecutive free throws is needed to raise it to 85%.

So, and equation we make is:

[tex]\frac{x}{15}[/tex] = 0.85, where x represents the number of free throws.

Now, we solve.

Multiply each side by 15 to solve for x.

x = 12.75

12.75 consecutive free throws is needed to raise the percent to 85%.

Answers

The first term, n = 1 = 2*1*1 = 2

Second term, n =2, = 2*2*2 = 8

Third, n =3, = 2*3*3 = 18

Third term, n = 4, = 2*4*4 = 32

Fourth term, n =5, 2 * 5* 5 = 50

For nth term, 2 *n *n = 2n²

Therefore nth term = 2n²
