Which fraction is less than the fraction represented by the model? A circle divided into 8 equal parts. 5 parts are shaded. Three-fourths Start Fraction 11 Over 16 End Fraction Start Fraction 13 Over 16 End Fraction Start Fraction 2 Over 4 End Fraction

Answers

Answer:

Step-by-step explanation:

The fraction represented by the model is 5/8. To compare it with the given fractions, we need to convert them to have the same denominator of 8.

- Start Fraction 11 Over 16 End Fraction = 11/16 = 0.6875

- Start Fraction 13 Over 16 End Fraction = 13/16 = 0.8125

- Start Fraction 2 Over 4 End Fraction = 2/4 = 1/2 = 0.5

To compare these fractions to 5/8, we can see that 0.5 is less than 0.625 (which is 5/8), so Start Fraction 2 Over 4 End Fraction is less than the fraction represented by the model. Therefore, the answer is Start Fraction 2 Over 4 End Fraction.

The rectangular prism is to be sliced perpendicular to the shaded face and is to pass through point A, perpendicular to the front face. What will the dimensions of the rectangular cross section be?

A rectangular prism. The rectangular base has a length of 4 inches and width of 3 inches. The height of the prism is 6 inches. Point A is at the top of the rectangle with length 6 inches and width 3 inches.
4 inches by 6 inches
4 inches by 3 inches
3 inches by 6 inches
2 inches by 6 inches

Answers

Answer:

C: 3 inches by 6 inches

Step-by-step explanation:

Notice that point A is a mid point. If we cut the prism though that point, perpendicular to the shaded face, it means the side of 4 inches will be divide in two equal parts, and the 3-6 inches face won't be cut.

Therefore, the dimensions of the cross section is 3 inches by 6 inches, which are the dimensions of the face that won't be cut, because they don't intersect with point A.

Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100. City Carpets charges $25 per square yard for the same carpeting, and an additional installation fee of $70. Write an equation and solve to find the number of square yards of carpeting for which the total cost charged by the two companies will be the same.

Answers

Answer:

22x + 100 = 25x + 70, 10 yards

Step-by-step explanation:

Set the number of square yards of carpeting as x.

So, the cost of Country Carpets is: 22 * x + 100

And the cost of City Carpets is: 25 * x + 70.

In order for the costs to be the , the equations need to be equal.

22x + 100 = 25x + 70

Subtract 22x from both sides.

100 = 3x + 70

Subtract 70 from both sides.

3x = 30

x = 10

the pigpen is not a square so it could be a rectangle or any other shape with four sides. since the pigpen has four equal angles and it's not a square it's a rectangle. one side of the pigpen is three feet long--REMEMBER THAT!!! one foot short of 7 feet is six feet and that is the distance around the pigpen or the perimeter

Time to solve

because the perimeter is 6 feet and one of the sides is three feetwe divide 6 by 3 and get two which is our widthwe then multiply 2x3 to get 6
Area=6

Answers

The equation would be y+3=(1/4)(x+3)
Gradient of the perpendicular line is the negative reciprocal of the original line.
