The two way table is attached.

According to the Venn diagram, 4 people own a car and a truck.  15+4=19 people own a car, and 4+9=13 people own a truck.  This leaves us 36-(15+4+9)=36-28=8 people that do not own a car or a truck.

We put 8 in the Don't Own a Truck row under the Don't Own a Car column.
We put 4 in the Own a Truck row under the Own a Car column.
We put 19 in the Total row under the Own a Car column.
We put 15 in the Don't Own a Truck row under the Own a Car column.

We put 13 in the Own a Truck row under the Total column.
We put 9 in the Own a Truck row under the Don't Own a Car column.
We put 23 in the Don't Own a Truck row under the Total column.
We put 8 in the Down Own a Truck row under the Don't Own a Car column.

We put 36 in the Total row under the Total column.
We put 17 in the Total row under the Don't Own a Car column.

Find m∠QPR..........
dexar [7]

Hey there! :)

Answer:

m∠QPR = 25°.

Step-by-step explanation:

Given:

m∠QPS = 40°

m∠RPS = 8x + 7°

m∠QPR = 9x + 16°

m∠QPS = m∠RPS + m∠QPR, therefore:

40° = 8x + 7° + 9x + 16°

Combine like terms:

40° = 17x + 23°

Subtract 23° from both sides:

17° = 17x°

Divide both sides by 17:

x = 1°

If m∠QPR = 9x + 16°, substitute in 1 for 'x':

9(1) + 16 = 9 + 16 = 25°.

Solve for A.................<br><br> H= A/2
grigory [225]

Step-by-step explanation:

First, multiply each side of the equation by

2

to eliminate the fraction while keeping the equation balanced:

2×A=2×h2(a+b)

2A=2×h2(a+b)

2A=h(a+b)

Now, divide each side of the equation by

a

+

b

to solve for

h

while keeping the equation balanced:

2Aa+b=h(a+b)a+b

2Aa+b=h(a+b)a+b

2Aa+b=h

h=2Aa+b
