Answer:

B

Step-by-step explanation:

Hey there! first, we divide 1 1/4 by 2 to get how much flour is used to make one muffin then we multiply 0.625by 12  because 1 1/4  ÷ 2 = 0.625

12 × 0.625 = 7.5            

  (7.5 is equivalent to 7 1/2)

Carol need  7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Carol used 1[tex]\frac{1}{4}[/tex] cups of flour in 2 muffins.

That means, Carol used 5/4 cups of flour in 2 muffins.

Unit rate = 2x4/5

              = 8/5

When we have 12 muffins,

then flour = 12x 5/8

                = 60/8

                = 7[tex]\frac{1}{2}[/tex] cups of flour.

Therefore, 7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.

The perimeter of the semi circle is gonna be π or 3.14

Step-by-step explanation:

So we know semi circle

The diameter is 2 so that basically also means the main circle diameter is also 2

we trying to find it’s circumference (perimeter)

C=πd

In this case d is 2

So 2π

And since that is full circle, half circle would be π

Step-by-step explanation:

-3x+10y=2

-3x+3y=9

-3x=2-10y

-3x=9-3y

2-10y=9-3y

2-9=10y-3y

7y=-7

y=-1

-3x+3(-1)=9

-3x-3=9

-3x=12

x=-4

Answer:

X=4, y=-1

Step-by-step explanation:

-3x+10y=2 multiple by 3

-3x+3y=9 multiply by 10

9x+30y=6

30x+30y=90

Subtract equation 1 from 2

30x-9x+30y-30y=90-6

21x+0=84

21x=84

Divide both side by 21

X=4

Substitute 4 for x in equation 1

3x+10y=2

3(4)+10y=2

12+10y=2

10y=2-12

10y=-10

Divide both side by 10

Y=-1

Answer:

A 40%

Step-by-step explanation:

The percentage of the people surveyed that are adults is; A: 40%

We are given;

Sample size of adults and children = 250

From the table, we see that;

Proportion of adults that can swim = 0.34

Proportion of adults that can't swim = 0.06

Thus;

Total proportion of Adults in the survey = 0.34 + 0.06

Total proportion of Adults in the survey = 0.40

Thus, percentage of people surveyed that are adults = 0.40 * 100% = 40%
