Set up a proportion.

The total side of the “top” line is 8 + 10 = 18. The total side of the “bottom” line is 45. This makes the ratio 18/45.

Now we are trying to find the “larger” bottom segment, let it be x. Because the lines are parallel, the ratio of the “larger” top and bottom segments is equal to the ratio of the whole top and bottom lines.

So 18/45 = 10/x

Reduce 2/5 = 10/x

Cross multiply 2x = 50

Solve x = 25

Consider circle H below.
hram777 [196]

We have been given a circle H, in which length of arc XY is 78 miles and measure of arc XY is 70 degrees. We are asked to find the radius of circle.

We will use arc length formula to solve our given problem.

\text{Arc length}=2\pi r\cdot \frac{\theta}{360^{\circ}}, where,

r = Radius of circle,

\theta = Central angle corresponding to arc.

We know that the measure of central angle that corresponds to arc XY will be equal to measure of arc XY.

78=2\cdot 3.14\cdot r\cdot \frac{70^{\circ}}{360^{\circ}}

78=2\cdot 3.14\cdot  r\cdot \frac{7}{36}

78= 3.14\cdot r\cdot \frac{7}{18}

78= r\cdot \frac{21.98}{18}

r\cdot \frac{21.98}{18}=78

r\cdot \frac{21.98}{18}\cdot \frac{18}{21.98}=78\cdot \frac{18}{21.98}

r=63.8762511373

Upon rounding to nearest hundredth, we will get:

r\approx 63.88

Therefore, the radius of circle H is approximately 63.88 miles.

Vaselesa [24]

Answer:

Naomi charges $8 an hour to mow lawns

Step-by-step explanation:

first day // 2 1/2= 2.5 hrs

2nd day // 4 1/4= 4.25 hrs

2.5hrs + 4.25hrs = 54hrs // 6.75hrs = 54hrs

/6.75    /6.75

= 8hrs

Really hope this helps!

Write the equation of a line with a slope of -7/2 passing through the point 2,-4
fiasKO [112]

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3
