Answer:Michelle paid $56.15 for her shoes

Step-by-step explanation:

Since Michelle paid $3.89 more for her shoes compared to Conrad, who paid $52.26. This means you have to add $3.89 to $52.26.

$3.89+$52.25= $56.15

Final answer:

Michelle paid $56.15 for her shoes, which is $3.89 more than the $52.26 that Conrad paid for his.

Explanation:

The question involves a simple arithmetic calculation to determine how much Michelle paid for her shoes. To find the answer, we will add $3.89, which is the additional amount Michelle paid, to $52.26, which is the amount Conrad paid for his shoes.

Step-by-step calculation:

Therefore, Michelle paid $56.15 for her shoes.

Answer:

[tex]\large\boxed{S.A.=1,119\ in^2}[/tex]

Step-by-step explanation:

We have:

two triangles with base b = 17in and height h = 7in

two rectangles with length l = 17in and width w = 10in

two rectangles with length l =11in and width w = 10in

one rectangle with length l = 8in and width w = 11in

one rectangle with length l = 15in and width w = 11in

one rectangle with length l = 17in and width w = 11in

The formula of an area of a triangle:

[tex]A_\triangle=\dfrac{bh}{2}[/tex]

b - base

h - height

The formula of an area of a rectangle:

[tex]A_{\boxed{\ }}=lw[/tex]

l - length

w - width

Calculate:

[tex]A_\triangle=\dfrac{(17)(7)}{2}=59.5\ in^2\\\\A_1=(17)(10)=170\ in^2\\\\A_2=(11)(10)=110\ in^2\\\\A_3=(8)(11)=88\ in^2\\\\A_4=(15)(11)=165\ in^2\\\\A_5=(17)(11)=187\ in^2[/tex]

The Surface Area:

[tex]S.A.=2A_triangle+2A_1+2A_2+A_3+A_4+A_5[/tex]

Substitute:

[tex]S.A.=2(59.5)+2(170)+2(110)+88+165+187=1,119\ in^2[/tex]

➷ As you can tell, the ratio of the lengths is 2 : 1 (the length of a is twice the length of b)

The ratio for area would be the squared version of the length ratio

2^2 = 4

1^1 = 1

The ratio for area is 4 : 1

Answer:

c)

Step-by-step explanation:

if you look at option c it would be correct because 0.75 (3/4) is bigger than 0.7. Then 11/12 is a bigger proportion then 0.75. there for your answer is correct.

The correct order of the numbers given when converted to decimals for easy comparison is 0.7, 3/4 and 11/12, which corresponds to option b: 0.7 < 3/4 < 11/12.

This is a question about comparing and ordering fractions and decimals. To answer this, we first need to convert all the numbers into the same format. We can convert the fractions 11/12 and 3/4 into decimals for easier comparison.

First, to convert 11/12 to a decimal, you'll do the division to find approximately 0.9167. Secondly, 3/4 can be converted to a decimal by performing 3 divided by 4, which equals 0.75. Now, we can easily compare these decimals to 0.7.

From this, we can see that 0.7 is less than 0.75 (3/4) and both 0.7 and 0.75 are less than 0.9167 (11/12). So the correct order of the numbers from least to greatest would be 0.7 < 3/4 < 11/12.

So the correct option is b. 0.7 < 3/4 < 11/12.

By dividing the 7 sandwiches into quarters, 28 quarters are available, allowing for 28 people to have 1/4 sandwich each.

The student has asked: "We have 7 sandwiches.

Everyone ate 1/4 sandwich for a snack.

To find out how many people can have sandwiches, we first need to understand how much of a sandwich each person gets.

Since each person ate 1/4 of a sandwich, we can take the total number of sandwiches (7) and divide them into quarters, giving us [tex]7 * 4 = 28[/tex] quarters of sandwiches.

Since each person eats one quarter, 28 people can have sandwiches.

Answer:

the answer is 16Ft^2

Step-by-step explanation:

Square A's area is 9 so take its square root =3

then do the same for Square c =5

then use pythagram theory which is

3^2 + 5^2 = 4^2 = 16

Answer:

area = 16 ft²

Step-by-step explanation:

The area of the green square = 9 ft²

area of the yellow square = 25 ft²

Area of the red square can be computed as follows:

area of a square = L²

Since one side of each triangle forms a part of the triangle knowing the length of sides of the green and yellow triangle can be use to get the sides of the red square and invariably the area.

Green square

L² = 9

square both sides

√L² = √9

L = 3 ft

Yellow square

L² = 25

square both sides

√L² = √25

L = 5 ft

use Pythagoras theorem to get the third side of the triangle which is the b

c² = a² + b²

b² = c²  - a²

a = 3 ft

c = 5 ft

b² =  5² - 3²

b² = 25 - 9

b² = 16

square both sides

√b² = √16

b = 4

Red square

area = L²

area = 4²

area = 16 ft²

Answer:

5.48

Step-by-step explanation:

32.45 - 26.97 = 5.48

Answer:

Jenna lost 5,48

Step-by-step explanation:

Before the diet Jenna's waist measured 32.45 inches.

After the  diet Jenna's waist measured 26.97 inches.

To get the difference between the two measures,  we have to discount the new measure from the previous one.

So,  difference is  26.97 inches-32.45 inches= -5,48. It is negative because she lost inches.

Answer:

Tonya cut the cylinder vertically and David cut it diagonally.

David’s cut along the length of his cylinder resulted in a rectangular cross-section, while Tonya’s perpendicular cut resulted in a circular cross-section. This illustrates principles of geometric cross-sections and plane intersections with solids.

In the problem described, David and Tonya are each cutting a cylinder, a geometric shape. The cuts they make, and the cross-sections they create, depend on the orientation of their cuts in relation to the shape of the cylinder.

When David cuts the cylinder, his cross-section result is a rectangle. This implies that he made a longitudinal cut along the length of the cylinder, essentially splitting it from top to bottom.

When Tonya cuts her cylinder, the cross-section is a circle. This means she made a cross-sectional cut perpendicular to the length of the cylinder, slicing it into two equal half cylinders.

This problem illustrates the principles of geometric cross-sections and plane intersections with solids, which are part of the broader field of study in geometry.

Answer:

y = 16

Step-by-step explanation:

The opposite angles of a parallelogram are congruent, hence

10y - 29 = 7y + 19 ( subtract 7y from both sides )

3y - 29 = 19 ( add 29 to both sides )

3y = 48 ( divide both sides by 3 )

Step-by-step explanation:

In your sample you have 26 out of 30. I like to get that number into a percentage, so you do 26 divided by 30

26/30 = .8666

Then you take your total amount of fans, 45,000 and multiply it by your percentage wearing team colors.

45,000 x .8666 = 38,999.97

Since you can't have .97 of a person, your round it down to 38,999.

P (S∩LC) = 0.03

Step-by-step explanation:

We are given that the probability that someone is a smoker is P(S)=0.19 and the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158.

Given the above information, we are to find the probability hat a random person is a smoker and has lung cancer P(S∩LC).

P (LC|S) = P (S∩LC) / P (S)

Substituting the given values to get:

0.158 = P(S∩LC) / 0.19

P (S∩LC) = 0.158 × 0.19 = 0.03

The correct answer is A.

To get back the original number after dividing by 9, one should multiply the result by 9, because multiplication and division are inverse operations.

The student's question asks: James thought of a number and divided it by 9. What can he do to get back his original number? The correct answer is (A) multiply by 9. When a number is divided by 9 to undo this operation one must multiply it by 9. This is because multiplication is the inverse operation of division. Therefore, if James wants to obtain his original number back, he should take the result he got after dividing by 9 and multiply it by 9.

Answer: 56*pi

Step-by-step explanation:

The easiest way is to find the area of the circle and subtract the area of the sector.

Area of the circle

d = 16 cm              given

d = 2*r                   definition

16 = 2*r                  divide by 2

16/2 = 2r/2

r = 8

Area of the circle = pi * r^2

Area of the circle = pi * 8^2

Area of the circle = 64 pi

Area of the sector

Area of sector = (theta/360) * pi * r^2

Area of sector = 45/360 * pi * 64

Area of sector = 1/8 * pi * 64

Area of sector = 8 * pi

Area of the shaded area

Area of the shaded area = 64 * pi - 8*pi = 56*pi

Note: There is a shorter way, but one can never be confident of getting an angle greater than 180 correct.

360 - 45 = 315

Area of the sector = 315/360 * pi * r2

Area of the sector = 7/8 * pi * 64

Area of the sector = 7 * pi * 8

Area of the sector = 56*pi
