Answer:

about 13.73 square feet

Step-by-step explanation:

We presume you want the area of the figure.

It can be decomposed into a triangle with base 3.6 ft and height 4.8 ft, together with a semicircle of diameter 3.6 ft.

The area of the triangle is given by ...

A = 1/2bh

For the given base and height, this is ...

A = (1/2)(3.6 ft)(4.8 ft) = 8.64 ft²

The radius is half the diameter, so the radius of the semicircle is 1.8 ft. The area of a whole circle of radius 1.8 ft is given by ...

A = πr² = π(1.8 ft)² = 3.24π ft²

We want the area of half the circle, so its area will be ...

semicircle area = (1/2)(3.24π ft²) = 1.62π ft² ≈ 5.089 ft²

Then the total area of the figure is ...

total area = triangle area + semicircle area

= 8.64 ft² + 5.09 ft²

total area = 13.73 ft²

15 Points!! Is this my teacher's fault? The math and the picture aren't making sense. The blue is my answer.

Answer:

Your teacher is correct.

Step-by-step explanation:

So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.

With this information in mind, we can create the expression:

2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)

Now simply the equation:

6x + 48 = 180

6x = 132

6x/6 = 132/6

x = 22

Angle C = 44

Angle B = 88

A retailer ordered a combination of 50 black and white sweatshirts. Each white sweatshirt cost him $10 and

Brut [27]

The number of white sweatshirts is 28

Step-by-step explanation:

Let ordered black shirts be represented by b

Let ordered white shirts be represented by w

So total sweatshirts will be represented by the equation

b+w=50

The total cost of the ordered sweatshirts will be represented by

10b + 12 w= $556

For simultaneous equations as;

b+w=50

10b+12w=556

solving the equations using substitution method where b=50-w

10(50-w)+12w=556

500-10w+12w=556

-10w+12w=556-500

2w=56

w=56/2= 28

b=50-w=50-28=24

Number of white sweatshirts is 28

Dale and 2 friends share one fourth of a cake.Each peice is the same size.Dale belives each peice of cake has an angle measure i

Umnica [9.8K]

Answer:

The correct answer is Dale is absolutely wrong.

Step-by-step explanation:

When the cake was complete, it had 360°. When the cake is divided into four halves each half now has 90° each.

Three person including Dale is about to eat the one fourth of the cake, divided among them equally.

Thus each friend gets $\frac{90}{3}$ ° = 30° of cake each.

But Dale claims that each piece of cake has an angle measure if 45°, which is a contradiction as each piece is supposed to to be equal.

Thus Dale is WRONG.
