You need to use the equation Distance (miles)=Rate (miles/hour) x Time (hours)

Brandi: 2.5 miles=rate (1/2 hour) r=5 miles per hour

Sharna=3.5 miles= rate (3/4 hour) r = 7 miles per hour.

Therefore brandi jogged at a slower rate.

Sharna jogged at a slower rate because she took approximately 1 minute more per mile than Brandi did.

A bug lands on a windshield wiper blade before it is flung off. The wiper blade and arm assembly have a length of 30 inches. If

sveticcg [70]

Answer:

35.6047 inches

Step-by-step explanation:

The wiper blade moves in a circular way, where the radius is 30 inches.

To find how far the bug travelled, we just need to use a rule of three, where the length of the circunference relates to a angle of 360 degrees:

360 degrees -> 2 * pi * radius

68 degrees -> distance

distance * 360 = 2 * pi * radius * 68

distance = 2 * pi * 30 * 68 / 360 = 35.6047 inches

Slove this inequality 3b-7 less the 20

Mars2501 [29]

Hi friend

#24

y/9+5=0

Simplify to both sides

1/9 y+5=0

Now subtract 5 from both sides

1/9 y+5-5=0-5

1/9 y=-5

Multiply both sides by 9 so we can find the y value

9(1/9 y)= (9)(-5)

y=-45

The answer is A ( Your answer was not good)

#25

3b-7<32

First you need to add 7 to both sides

3b-7+7=32+7

3b<39

Now divide both sides by 3 so we can find the value for b

3b/3<39/3

b<13

The answer is A

#26

3p-16<20

Now we gonna do the same thing

Add 16 to both sides

3p-16+16<20+16

3p<36

Now divide both sides by 3

3p/3<36/3

p<12

The answer is C

#27

3p-6>21

Just do the same thing

Add 6 to both sides

3p-6+6>21+6

3p>27

Divide both sides by 3

3p/3>27/3

p>9

The answer is B

I really hope that's help and good luck :0

= The average score of Karl's first four math tests is 72 points. After the fifth and the sixth tests, his average score increas

mylen [45]

Answer:

83 points

Step-by-step explanation:

-The formula for average is given as:

$\bar X=\frac{1}{n}\sum{x_i}\\\\x_i=Individual \ Test \ scores\\n=number \ of \ scores$

Let a be his 5th score and (a+4) of the 6th

#We subtract the sum of the first 4 tests from the 6, to get the sum of the 5th and 6th tests:

$(6^{th}+5^{th})=\bar X n_6-\bar X n_4\\\\=75\times 6-72\times 4\\\\=162$

#We substitute for the 5th and 6th to solve a:

$5^{th}=a\\6^{th}=a+4\\\\a+(a+4)=162\\\\2a=158\\\\a=79\\\\6^{th}=a+4=79+4=83$

Hence, Karl score 83 points in his 6th test.
