  2. C=50.24mi.               A=200.96mi.²
  3. C=25.12in.                  A=50.24in.²
  4. C=37.68Km               A=113.04Km²

Step-by-step explanation:

C=2 \pi x r

so for c you times 2 \pi by your radius

Area is \pi times diameter (diameter is two times your radius)

In a certain year, there were 88 female officials in Congress, which is comprised of the House of Representatives and the Senate
Ainat [17]

Answer:

  • 71 in House of Representatives
  • 17 in Senate

Step-by-step explanation:

Let h and s represent the numbers in the House and Senate, respectively. Then we have ...

  h + s = 88

  h - s = 54

Subtracting the second equation from the first gives ...

  (h +s) -(h -s) = (88) -(54)

  2s = 34 . . . . . simplify

  s = 17 . . . . . . . divide by 2

  h = 88 -17 = 71 . . . . find the other value using the sum equation

There were 71 females in the House of Representatives, and 17 females in the Senate.

Figure ABCD is a parallelogram
Nadya [2.5K]

The first thing we must do for this case is to find the relationship between the variables.

We have then:

AB = DC\\4y - 2 = 2y + 6

From here, we clear the value of "Y":

4y - 2y = 6 + 2\\2y = 8

y = \frac{8}{2}\\y = 4

On the other hand we have:

AD = BC\\3x - 1 = 2x + 2

From here, we clear the value of "x":

3x - 2x = 2 + 1\\x = 3

Then, replacing values we have:

AB = DC = 4y - 2 = 4 (4) - 2 = 16 - 2 = 14\\AB = DC = 14

On the other hand:

AD = BC = 2x + 2 = 2 (3) + 2 = 6 + 2 = 8\\AD = BC = 8

Finally, the perimeter is given by:

P = AB + DC + AD + BC

Substituting values we have:

P = 14 + 14 + 8 + 8\\P = 44

Answer:

the perimeter of ABCD is:

44 units

35 people paid a total of $245 for admission to a local soccer game. What is the price of admission?
DIA [1.3K]

35 people paid a total of $245 for admission to a local soccer game. What is the price of admission?

Answer: We are given that 35 people paid total of $245 for admission.

Now we need to find the price of one admission. To find the price of one admission we need to divide the total amount paid by the number of people.

Therefore, the price of admission is:

\frac{245}{35}=\ 7

What is the solution for the following system of equations? Use ANY method to solve. 2x + 8y = 4 x = -3y + 5 Question 4 options:
Elan Coil [88]

Answer:

x = 14, y= -3

Step-by-step explanation:

Solve the following system:

{2 x + 8 y = 4 | (equation 1)

{x = 5 - 3 y | (equation 2)

Express the system in standard form:

{2 x + 8 y = 4 | (equation 1)

{x + 3 y = 5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + 8 y = 4 | (equation 1)

{0 x - y = 3 | (equation 2)

Divide equation 1 by 2:

{x + 4 y = 2 | (equation 1)

{0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:

{x + 4 y = 2 | (equation 1)

{0 x+y = -3 | (equation 2)

Subtract 4 × (equation 2) from equation 1:

{x+0 y = 14 | (equation 1)

{0 x+y = -3 | (equation 2)

Collect results:

Answer:  x = 14, y = -3
