A cup of milk has 10 grams of protein. How much protein is in 2.5 cups of milk?

Answers

Answer:

25 grams of protein

Step-by-step explanation:

10 grams of protein is in 1 cup of milk.

To understand how many grams of protein are in 0.5 cups of milk, I would need to divide 10 by 2, to get 5.

There are 5 grams of protein in 0.5 cups of milk.

Now if I want to see how many grams of protein are in 2 cups of milk, I would multiply 10 by 2, to get 20.

There are 20 grams of protein in 2 cups of milk.

But, the question is asking for how much protein is in 2.5 cups of milk.

Since we know how much is in 2 cups, and 0.5, we can just add them together, because 2+0.5 is 2.5.

20+5 is 25 grams.

There are 25 grams of protein in 2.5 cups of milk.

What is the slope of the line through (-7,-2) and (−6,7)?

Answers

Answer:

slope = 9  

Step-by-step explanation:

To find the slope of a line that passes through a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (-7,-2) and (-6,7) into the formula and simplify:

[tex]m = \frac{(7)-(-2)}{(-6)-(-7)} \\m = \frac{7+2}{-6+7} \\m = \frac{9}{1} \\m = 9[/tex]

So, the slope is 9.

Shanna deposit 11,500 and leaves the funds in her account for 14 years how much will she have if the interest rate of the bank offered 4.9%

Answers

Hello!

This is a problem about interest rates.

Since we are not given the "[tex]n[/tex]" value, how many times this interest applies per time period, we can assume that we are most likely dealing with simple interest with an annual interest rate.

The simple interest formula is as follows,

[tex]A=P(1+rt)[/tex]

Where [tex]A[/tex] is the total amount, [tex]P[/tex] is the initial principal balance, [tex]r[/tex] is the annual interest rate, and [tex]t[/tex] is time in years.

Since we are given all this information, we can just solve after converting the interest rate of 4.9% to a decimal, which is 0.049.

[tex]A=11500(1+0.049*14)[/tex]

[tex]A=11500(1.686)[/tex]

[tex]A=19389[/tex]

So at the end of the 14th year, Shanna will have $19,389 in her account.

A rectangular window is 3.5 feet wide and has an area of 19.25 square ft you have six yards of string light do you have enough string lights to outline the window with light

Answers

Answer:

yes

Step-by-step explanation:

We are to determine if 6 yards is enough t to go round the perimeter of the window

The length is not given, so we have to determine the length from the area

Area of a rectangle = length x breadth

19.25 = 3.5 x length

length = 5.5 feet

Perimeter = 2 x ( length + breadth )

2 x (5.5 + 3.5) = 18 feet

We need to convert the string to foot

1 yard = 3 foot

6 x 3 = 18 foot

the string and the perimeter are equal, so it is enough

The owner of a tree farm plants pine trees and oak trees in a ratio of 8:3. How many oak trees are planted if 264 pine trees are planted

Answers

Answer:

99 oak trees

Step-by-step explanation:

Given data

Ratio= 8:3

Number of pine tree= 264

Let the number of oak trees be x

Let us apply the part to part method

8/264= 3/x

cross multiply

264*3= 8x

792=8x

x= 792/8

x=99 oak trees

The owner of the tree farm planted 99 oak trees.

An equation is an expression used to show the relationship between two or more numbers or variables.

Given that a farmer plants pine trees and oak trees in a ratio of 8:3. If 264 pine trees are planted, let y represent the total number of trees hence:

264 = (8/11) * y

y = 363 trees

Number of oak trees = (3/11) * 363 = 99 trees

Therefore the owner of the tree farm planted 99 oak trees.
