Answer:

He now work 24 hours each week

Step-by-step explanation:

Dylan works 30 hours a week. His hours are decreased by 20%.

The number of work hours 30 is decreased by 20%

we need to find 20% of 30

30 \cdot \frac{20}{100} =6

So number of hours should be decreased by 6

30-6= 24

he now work 24 hours each week

Jessie recently drove to visit her parents who live 240240 miles away. On her way there her average speed was 2525 miles per hou
dusya [7]

Answer:

The speed/rate to her parent's house is x = 75 mph

The speed/rate from her parent's house is y = 50 mph

Step-by-step explanation:

Given;

Distance to her parent's house = 240 miles

Total distance travelled (to and fro) = 240×2 = 480 miles

Total time taken t = 8 hours

On her way there her average speed was 25 miles per hour faster than on her way home (she ran into some bad weather)

Let x and y represent her speed to and from her parent's house respectively.

x = y+25 ......1

The time taken to her parent's house is;

time = distance/velocity

t1 = 240/x = 240/(y+25)

The time taken from her parent's house is;

time = distance/velocity

t2 = 240/y

Total time taken t = t1 +t2

t = 240/(y+25) + 240/y = 8

Solving for y ;

(240y + 240(y+25))/(y^2 +25y) = 8

Cross multiply;

240y + 240y+6000 = 8y^2 + 200y

480y +6000 = 8y^2 + 200y

8y^2 + 200y -480y -6000 = 0

8y^2 - 280y - 6000 = 0

Divide through by 8;

y^2 - 35y - 750 = 0

Solving the quadratic equation;

y = 50

or

y = -15

Velocity cannot be negative, so y = 50mph

From equation 1;

x = y+25

Substituting y =50

x = 50 + 25

x = 75 mph

The speed/rate to her parent's house is x = 75 mph

The speed/rate from her parent's house is y = 50 mph

Raymond was riding a zip-cable from the top of a viewing post. The cable is 70 yards long. The viewing post is 56 yards high and
Marysya12 [62]

Answer:

C. 42 yards

Step-by-step explanation:

You may recognize this as a 3-4-5 right triangle with a scale factor of 14. The two given sides are 5·14 = 70 and 4·14 = 56. Then the missing side is 3·14 = 42.

If not, you can use the Pythagorean theorem in the usual way:

... hypotenuse² = leg1² +leg2²

... 70² = 56² +leg2²

... leg2 = √(70² -56²) = √1764 = 42 . . . . yards

The cable is anchored 42 yards from the  base of the tower.
