It was 96 kilometers from perry to medford. David raced to medford and idled back. If the round trip took 8 hours, what was his average speed in kilometers per hours?

Answers

Average speed = (total distance) / (total time)

Average speed = (192 km) / (8 hours) = 24 km per hour .

Time for round trip = 8 hours

thus, time for trip = 8/2 = 4 hours.

Speed = distance / time

= 96/4 = 24 km/h

Thus, his average speed was 24 km/h

Monique collects data from a random sample of seventh graders in her school and finds that 8 out of 16 seventh graders participate in after-school activities.

A rectangular prism is 4 meters long, 5 meters wide, and has a height of 7 meters. What is its surface area?140 m 2
166 m 2
84 m 2
70 m 2

Answers

Answer:

The surface area of rectangular prism is 166 m².

Step-by-step explanation:

Given that,

length l= 4 m

Width b= 5 m

Height h=7 m

Using the formula of surface area of rectangular prism

$A= 2(bh+lb+lh)$

We substitute the value into formula

$A= 2(5*7+4*5+4*7)$

$A= 2(35+20+28)$

$A=2*83$

$A= 166 m^2$

Hence, The surface area of rectangular prism is 166 m².

Answer:

166 m^2

The scores of the top ten finishers in a recent golf tournament are listed below. find the median score. 67 67 68 71 72 72 72 72 73 76a. 72
b. 71
c. 73
d. 67

Answers

Answer:

(A) 72

Step-by-step explanation:

Find the middle(or middle two) values:

67 67 68 71 72 72 72 72 73 76

1 2 3 4 5 6 7 8 9 10

^ ^

Now find the mean of the two middle values: (72+72)/2 = 72.

Therefore, the median value is 72 or (A).

Final answer:

The median score of the top ten finishers in the golf tournament is 72.

Explanation:

To find the medianscore, we need to arrange the scores in ascending order. The scores are: 67, 67, 68, 71, 72, 72, 72, 72, 73, 76. The middle score is the median. Since there are 10 scores, the middle score is the 5th score in the ordered list, which is 72. Therefore, the median score is 72.

Elimination method

-2x+y=-8
2x+4y=18

Answers

We have to add first eq to second eq.
-2x+y+2x+4y=-8+18
5y=10 /:5
y=2
Now we can backsubstitute
2x+4*2=18
2x+8=18 /-8
2x=18-8
2x=10 /:2
x=5
Finally we obtain result
x=5
y=2

elimitation method
basically eliminate one of the terms completely
we see that there is a -2x and a 2x in the 2 equations
so just add them together
2x-2x+4y+y=18-8
5y=10
divide both sides by 5
y=2

subsitute
-2x+2=-8
subtract 2 form boht sides
-2x=-10
divide both sides by 2
-x=5
multiply -1
x=5

y=2
x=5
