Answers

Answer 1

Answer:

Answer: She needed $1(1)/(2)\text{ pounds of blueberries}$ to make a cup of jam .

Step-by-step explanation:

Since we have given that

Sarah used $(3)/(4)$ pound of blueberries to make $(1)/(2)$ cup of jam.

As we need to find the number of pounds of blueberries she would need to make a cup of jam.

So, we will use "Unitary Method":

$\text{For }(1)/(2)\text{ cup of jam},\n\n\text{ she need }(3)/(4)\text{ pound of blueberries }\n\n\text{ For 1 cup of jam}.\n\n\text{She need }=(3)/(4)* 2=(3)/(2)=1(1)/(2)\text{ pounds of blueberries }$

Hence, She needed $1(1)/(2)\text{ pounds of blueberries}$ to make a cup of jam .

What is the approximate circumference of a semicircle with a radius of 30 centimeters

Answers

Approximate circumference of a semicircle with a radius of 30 centimeters is 94.2 centimeter

Solution:

Given semicircle with a radius of 30 centimeters

To find: approximate circumference of a semicircle

To find circumference of semicircle we can divide the circumference of circle by 2

circumference of semicircle = circumference of circle $/$ 2

$\text{ circumference of semicircle} = (2 \pi r)/(2) = \pi r$

Substituting the given radius = 30 cm,

$\text{ circumference of semicircle} = 3.14 * 30 = 94.2$

Thus approximate circumference of a semicircle with a radius of 30 centimeters is 94.2 centimeter

Answer:

94.2

the triangle on the left area is 18 because the area of a triangle is 1/2 b times h so 12 times 3 times 1/2 equals 18.you then cut a triangle from the quadrilateral to make into a triangle.The triangle is the same height has other triangle so its area is 18.Since you took three for base of left and right triangle you subtract 6 from 1 to make it your base of 8 and your height is 12 and 12 tikmes 8 is 96 so 18+18+96=132 so our answer is 132.
