Answer:

Angle 1= 180 - 110 = 70 (straight angle)

Angle 2 = 180 - 115 =65 (straight angle)

Angle 3= angle 2 =65 (corresponding alternating angles)

Angle 4 =180 - angle3 = 180 - 65 = 115 (straight angle)

Angle 5 = 180 - angle 1 - angle 3= 180 - 70 - 65 = 45 (sum of triangle angles is equal to 180)

Angle 6 = angle 5= 45 ( interior alternating angles)

Angle 7 = angle 6= 45 (vertical opposite angles)

How to find volume of 7 and 8? (20 pts)

Airida [17]

Answer:

Step-by-step explanation:

7.base of triangle=√(32.5²-28²)

=√4.5(32.5+28)

=√4.5(60.5)

=√272.25

=16.5

area of triangle=1/2 ×16.5×28

=231

volume=231×31=7161 km³

39.4-25=14.4

width=√(30.6²-14.4²)

=√16.2(30.6+14.4)

=√16.2(45)

=√729

=27

volume=(25+39.4)/2 ×27×35

=(64.4)/2×27×35

=32.2×27×35

=30429 cm³

...2 can go into both of them...

36 / 10

(÷2) (÷2)

18 / 5

Now we have to see if any other number goes in to these new numbers...

There are no numbers that goes into both...

exis [7]

Her estimate is not accurate because if you multiply 30 by 11 you would get 330. Then you multiply that by 52and you would get $10560 a year.

John had to pay a combined electric and gas bill $150. The electric portion of the bill was $90. What is the ratio of money spen

tatuchka [14]

Given:

John had to pay a combined electric and gas bill $150.

The electric portion of the bill was $90.

To find:

The ratio of money spent on electric to that on gas.

Solution:

Let x be the amount of gas bill.

The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150. So,

$90+x=150$

$x=150-90$

$x=60$

The gas portion of the bill was $60.

The ratio of money spent on electric to that on gas is:

$\text{Required Ratio}=\dfrac{\text{Electric bill}}{\text{Gas bill}}$

$\text{Required Ratio}=\dfrac{90}{60}$

$\text{Required Ratio}=\dfrac{3}{2}$

$\text{Required Ratio}=3:2$

Therefore, the ratio of money spent on electric to that on gas is 3:2.
