Answer:

C  459cm2

Step-by-step explanation:

You multiply the area of the square first and add that to the area of the two right triangles.

<u>Area of the square</u> - Bh = 22(18) = 396

<u>Area of ONE right triangle</u> - 1/2bh    h = 7    b = the base of the triangle

Look at the bottom of the square (18 cm) and divide that by two to get the base of the triangle

1/2(9)(7) = 31.5

<u>Area of BOTH right triangles </u>- 31.5(2) = 63

<u>Total Area</u> - Then you add 396 to 63 and you get 459 cm2, or C, which is the answer

In a survey of 400 seniors, x percent said that they plan on majoring in physics. One university has used this data to estimate
azamat

Answer:

2 percent

Step-by-step explanation:

We can use two separate fractions, one representing the amount of physics majors expected and the amount of seniors expected in physics majors by the university.

\frac{400x}{66} = \frac{400}{3600}

Now cross multiply.

\frac{66*400}{400x * 3600}

x will be removed.

\frac{26400}{1320000}

Simplifying this fraction will get you \frac{1}{50}, which in percentage form, will be 2 percent.

Write a formula to describe the sequence
Dominik [7]

Answer:

d

Step-by-step explanation:

A(n) = 1 - 0.1(n-1)

A(1) = 1- 0.1*(1-1) = 1 - 0.1*0 = 1

A(2) = 1- 0.1*(2-1) = 1 - 0.1*1 = 1- 0.1 = 0.9

A(3) = 1 - 0.1(3-1) = 1 - 0.1*2 = 1-0.2=0.8

Method:

A(1)=1

D = A(2)-A(1) = 0.9 - 1 = -0.1

A(n) = A(1)+(n-1)*d = 1 + (n-1)*(-0.1)

     = 1 - 0.1(n -1)

With a tailwind, a aircraft can fly 360 miles in 3 hrs. Against this same wind, the aircraft can fly the same distance in 4hrs.
Leona [35]

Answer:

15mph

Step-by-step explanation:

360 divide by 3 =  120

360 divide by 4 = 90

120 - 90 = 30

30 divide by 2 (cause boosting speed and drag) = 15

so let's check

120-15=105

105+15=120

105-15= 90

so the answer's 15.
