400

Explanation:

1/3 of 600 is 200. That represents the boys.

Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).

1. EFG

2. F

3. FA and FB Take a moment to look at this one. The two rays are pointing in opposite directions. They are 180o apart. They share a common point at F.

FE and FG does the same thing.

4. No G is on a line that has only one point on the plane and that point is F.

5, AC has an infinite number of points on the plane.

The side is (2x+3)? then the area is: (2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then Area = 4(36)+12(6)+9 = 144 + 72 + 9 = 225, too big :(

The amount of fabric in inches Felicia need to make the actual shape for the comforter is 660 in²

<h3>What is a trapezoid?</h3>

It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.

We have a trapezoid in the picture shown with dimensions.

We know the area of the trapezoid is given by:

$\rm A = \dfrac{a+b}{2} \times h$

Here a = 15 cm, b = 22 cm and h = 11 cm

$\rm A = \dfrac{15+22}{2} \times 11$

A = 203.5 square cm

To make the square from the trapezoid, Felicia needs to cut two triangles from the both end, as shown in the figure.

The height of the triangle = 11 cm

And base length = (22-15)/2 = 3.5 cm

The area of the triangle = (11×3.5)/2 = 19.25 square cm

Area of the two triangles = 2×19.25 = 38.5 square cm

Now the amount of fabric = 203.5 - 38.5 = 165 square cm

As the scale is given 1 cm = 2 in

1 cm ² = 4 in²

So, the amount of fabric in inches = 165×4 = 660 in²

Thus, the amount of fabric in inches Felicia need to make the actual shape for the comforter is 660 in²

Question 2 Answer Solve

Lelu [443]

Answer:

Option B is correct.

Step-by-step explanation:

To subtract fractions, we must check if the denominators of both fractions are the same.

2/5 - 1/7
=> 2 x 7/5 x 7 - 1 x 5/7 x 5
=> 14/35 - 5/35

Now, let's subtract for the result.

=> 9/35

Hence, Option B is correct.

Hoped this helped.
