The percentage of pizza Marissa ate was 37.5 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the percentage of pizza Marissa ate be = A

Let the total number of slices in the pizza be = 16 slices

Let the number of slices of pizza Marissa ate be = 6 slices

So , the equation will be

The percentage of pizza Marissa ate A = ( number of slices of pizza Marissa ate / total number of slices in the pizza ) x 100

On substituting the values in the equation , we get

The percentage of pizza Marissa ate A = ( 6 / 16 ) x 100

The percentage of pizza Marissa ate A = ( 3 / 8 ) x 100

The percentage of pizza Marissa ate A = 0.375 x 100

The percentage of pizza Marissa ate A = 37.5 %

Therefore , the value of A is 37.5 %

Hence , The percentage of pizza Marissa ate was 37.5 %

Options:

(12,0)     (0,12)    (3,-1)    (0,-4/3)

Answer:

(12,0) ,  (3,-1)  and (0,-4/3)

Step-by-step explanation:

Given

[tex]x - 9y = 12[/tex]

Required

Which option is true?

A coordinate point is of the form; [tex](x,y)[/tex]

So, we have to substitute the x and y values in the given equation.

A. For (12,0)

[tex]x = 12[/tex] and [tex]y = 0[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]12 - 9*0 = 12[/tex]

[tex]12 - 0 = 12[/tex]

[tex]12 = 12[/tex]

This is true

B. For (0,12)

[tex]x = 0[/tex] and [tex]y = 12[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]0 - 9*12 = 12[/tex]

[tex]- 9*12 = 12[/tex]

[tex]- 108 = 12[/tex]

This is false

C. For (3,-1)

[tex]x =3[/tex] and [tex]y = -1[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]3 - 9*-1 =12[/tex]

[tex]3 + 9 =12[/tex]

[tex]12 = 12[/tex]

This is true

D. For (0,-4/3)

[tex]x = 0[/tex] and [tex]y = -\frac{4}{3}[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]0- 9*-\frac{4}{3} = 12[/tex]

[tex]0+ 9*\frac{4}{3} = 12[/tex]

[tex]0+ 3*4 = 12[/tex]

[tex]0+12 = 12[/tex]

[tex]12 = 12[/tex]

This is true

Hence, (12,0) ,  (3,-1)  and (0,-4/3) are true values of the equation

Answer:

75% increase

Step-by-step explanation:

First we need to figure out how many new records she got this year...

7-4 = 3 new records.

Now, we need to know how many times 4 goes into 100%....

100 ÷ 4 = 25%

This tells us that a single record this year is a 25% increase.

Now, we multiply 25% by 3 to get 75% as our final answer

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Step-by-step explanation:

Adrian answered 7/8 of 32 questions, so the number he finished is ...

  (7/8) × 32 = (7×32)/8 = 7×(32/8) = 7×4 = 28

Adrian answered 28 questions.

Answer:

12 units

Step-by-step explanation:

Given that :

R(-3,2)

S(2,2)

T(2,-5).

The total length ;

Distance between two points : √[(x2 - x1)² + (y2 - y1)²]

Distance between R and S :

R = (-3,2)

S(2,2)

√[((2 - (-3))^2 + (2 - 2)^2]

Sqrt(5^2 + 0^2)

D1 = 5 units

Distance between S and T:

S(2,2)

T(2,-5).

D2 = √[(2 - 2)^2 + (-5 - 2)^2]

D2 = sqrt(0^2 + (-7)^2)

D2 = 7 units

Hence, total length = D1 + D2 = (5 + 7) = 12 units

Answer:

Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.

This gives you: 1 - 4 - 7 + 10 = 0.

Because 0 = 0 is a true statement, you know that x = 1 is a solution.

The answer of the given question based on the word problem of multiplication is , option (c) Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.

Total cost refers to the complete amount of money required to purchase or produce a given quantity of goods or services. It includes all the expenses involved in the production or purchase of the product or service, like materials, labor, and overhead costs, as well as any other additional expenses like  taxes or shipping fees. Total cost is an important concept in economics and accounting as it helps businesses and individuals to determine the profitability of a product or service and make informed decisions about pricing and production.

The answer is: "Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00."

Rounding can be used to estimate the total cost of the stamps by approximating the cost of each stamp to the nearest 50 cents, which is $0.50. Therefore, the cost of four stamps can be estimated as 4 multiplied by 0.50, which is $2.00.
