Morgan is throwing a pizza party. She has 1 7/8 pounds of cheese available and she needs 1/5 pound of cheese to make each pizz

Karolina [17]

We have been given that Morgan is throwing a pizza party. She has 1 7/8 pounds of cheese available and she needs 1/5 pound of cheese to make each pizza. We are asked to find the number of full pizzas that Morgan can make with the amount of cheese she has.

To solve our given problem, we will divide total amount of cheese by amount of cheese used to make each pizza.

$\text{Number of pizzas}=1\frac{7}{8}\div \frac{1}{5}$

$\text{Number of pizzas}=\frac{15}{8}\div \frac{1}{5}$

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction.

$\text{Number of pizzas}=\frac{15}{8}\times \frac{5}{1}$

$\text{Number of pizzas}=\frac{75}{8}$

$\text{Number of pizzas}=9\frac{3}{8}$

We are asked to find the number of full pizzas and we can see that Morgan can make 9 full and $\frac{3}{8}$ pizzas.

Since there are 9 full pizzas, therefore, Morgan can make 9 full pizzas with the amount of cheese she has.

PLEASEEEEEEE HELP with this question

nikklg [1K]

Answer:

second table

Step-by-step explanation:

Out of the 8 options on the spinner, 2 of them are 0's, 1 of them is a 1, 2 of them are 2's and 3 of them are 3's so the probability of spinning a 0, 1, 2 or 3 is 2/8, 1/8, 2/8 or 3/8 which becomes 0.25, 0.125, 0.25 or 0.375 respectively. Therefore, the answer is the second table.

On a test that has a normal distribution, a score of 32 falls three standard

lions [1.4K]

Answer:

Mean = 62

Step-by-step explanation:

X = mean ± sd

82 = mean + 2(s.d) - - (1)

32 = mean - 3sd ___(2)

82 = mean + 2sd

82 - 32= 2sd + 3sd

50 = 5sd

sd = 50/5

sd = 10

From (2):

32 = mean - 3sd

32 = mean - 3(10)

32 = mean - 30

32 + 30 = mean

62 = mean

A supporting goods store sells 2 fishing reels and 5 fishing rods for $243. Later, they still 8 fishing reels and 6 fishing rods

Gwar [14]

To answer this, you can set up a system of equations. Solve for one of the variables and substitute this new equation into the 2nd equation.

2x + 5y = 243 - I'll solve this one for x.
8x + 6y = 538

2x + 5y = 243
2x = 243 - 5y
2 2
x = 121.5 - 2.5y ; substitute this in for x in the second equation

8x + 6y = 538
8 (121.5 - 2.5y) + 6y = 538
972 - 20y + 6y = 538
972 - 14y = 538
-972 -972
-14y = -434
-14 -14
y = 31

<u><em>The cost of a rod (y) is $31. </em></u>

x = 121.5 - 2.5y
x = 121.5 - 2.5 x 31
x = 44

<em><u>The cost of a reel(x) is $44.</u></em>

Question 7: Solve this system<br><br> A.(15, 10)<br> B.(-15, 10)<br> C.(-10, 25)<br> D.(10, 15)

Alexandra [31]

Answer:

D. (10, 15)

Step-by-step explanation:

Hi there!

We are given the following system:

$\frac{1}{2}x$ +y=20

x+4y=70

And we want to solve it (find the values of x and y).

Let's use substitution for this problem, where we will isolate one variable on one side, while the other side contains an expression with the other variable. Then, we use the expression to solve for the variable that the expression contains, then use the value of that variable to solve for the aforementioned isolated variable.

Subtract $\frac{1}{2}x$ from both sides in the first equation

y=20- $\frac{1}{2}x$

Now substitute 20- $\frac{1}{2}x$ as y in x+4y=70

x+4(20- $\frac{1}{2}x$ )=70

Do the distributive property

x+80-2x=70

Combine like terms on the left

-x+80=70

Subtract 80 from both sides

-x=-10

Multiply both sides by -1

x=10

We found the value of x. Now let's use that value to find what y is

Since we know that y=20- $\frac{1}{2}x$ and x=10, we can substitute 10 as the value of x to solve for y

In that case,

y=20- $\frac{1}{2}$ (10)

Multiply

y=20-5

Subtract

y=15

The answer is x=10, y=15, or as a point, <u>(10, 15), aka D</u>

Hope this helps!
