Answer: 43.75 ft^2

Step-by-step explanation:

Divide this figure into the rectangle and the triangle.

The area of a rectangle is A=l*w

A=5*6.25=31.25 ft^2

The area of a triangle is A= (l*w)/2

l=5ft

w=(11.25-6.25)=5ft

A=(5*5)/2=12.5 ft^2

31.25+12.5=43.75 ft^2

Find the circumference and area of the following circle. A circle with a diameter of 29 feet

choli [55]

Answer:

Step-by-step explanation:

The circumference of a circle in terms of the diameter is

$C=\pi d$

If our diameter is 29 feet, then the circumference, in terms of pi is

$C=29\pi ft$ .

If we are multiplying in pi as 3.14, then it is

C = 91.06 ft

The area formula for a circle is

$A=\pi r^2$

If the diameter is 29, then the radius is half of that at 14.5 feet. Filling in:

$A=\pi(14.5)^2$

so, in terms of pi, the area is

$A=210.25\pi ft^2$ or if you multiply pi in as 3.14, then you get:

$A=660.185 ft^2$

If Mary deposits $275 in principal at an interest rate of 3.2 percent, how much interest will she earn in one year

nekit [7.7K]

Answer:

Mary earns interest in one year is $88 .

Step-by-step explanation:

Formula

$Simple\ interest = \frac{Principle\times rate\times time}{100}$

As given

If Mary deposits $275 in principal at an interest rate of 3.2 percent .

Principle = $275

Rate = 3.2%

Time = 1 year

Putting all the values in the formula

$Simple\ interest = \frac{275\times 3.2\times 1}{100}$

$Simple\ interest =\frac{880}{100}$

Simple interest = $88

Therefore the Mary earns interest in one year is $88 .

!50 point question! Find x and explain how you found it!

STatiana [176]

Answer:

$\sf x = 60^{\circ \:}$

given:

adjacent side: 10
hypotenuse side: 20

using cosine rule:

$\hookrightarrow \sf cos(x) = \dfrac{adjacent}{hypotense}$

$\hookrightarrow \sf \sf cos(x) = \dfrac{10}{20}$

$\hookrightarrow \sf \sf x = cos^{-1}(\dfrac{10}{20} )$

$\hookrightarrow \sf \sf x = 60^{\circ \:}$
