The Hendrix family was draining their pool at the end of
summer. They found that the water level goes down by 0.4
feet every hour. If the water level in the pool has changed by
-1.4 feet, how long have they been draining the pool?

Answers

Answer 1

Answer:

3.5 hours

Step-by-step explanation:

If the water goes down by 0.4 feet every hour

we can add 0.4 + 0.4 + 0.4 (0.4 x 3) and get 1.2 and 1.4 - 1.2 - 0.2

And we also know that half of 0.4 is 02 so we can add 0.2 to 1.2 in order to get our desired answer. Which is 1.4 So now let's add what we multipleied by

3 + 1/2 = 3.5

If the line is tangent that means it forms a 90 degree angle. The angle measure of the inside of a triangle is equal to 180 degrees. If you add 52 and 90 you get 142. Subtract this amount from 180 and you will get the measure of m TMS

Teammates Pedro and Ricky got 2679 base hits last season. Pedro had 281 more hits than Ricky.
How many hits did each player have?

Answers

9514 1404 393

Answer:

Pedro: 1480Ricky: 1199

Step-by-step explanation:

Let r represent the number of hits Ricky got. Then Pedro's hits were r+281 and their total was ...

  r + (r +281) = 2679

  2r = 2398

  r = 1199

  r+281 = 1480

Pedro got 1480 hits; Ricky got 1199.

_____

Additional comment

The two answers to a "sum and difference" problem are half the sum plus or minus half the difference. Here, those values are (2679/2) ± (281/2). Pedro got more hits, so his number is (2679+281)/2 and Ricky's number is (2679-281)/2, as above.

The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?

Answers

Answer:

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

(9×11)=99

the length of the longest side= 99inches

9e + 4=5e + 14 + 13e

Answers

Answer:

e = -1

Step-by-step explanation:

1. 9e + 4 = 5e + 14 + 14e

2. 9e = 5e + 10 + 14e

3. 9e = 19e +10

4. -10e = 10

5. e = -1

Hope that helps

Answer:

e - 10

Step-by-step explanation:

1.) We need to manipulate the equation to get e by itself.

2.) To solve the equation, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e (Combine like terms)

9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)

e + 4 = 14 (Combine like terms)

e + 4 - 4 = 14 - 4 (Subtract 4 from each side)

e = 10 (Combine like terms.

3.) Answer: e = 10.

Now lets check our work. To check your work, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e

9(10) + 4 = 14 + 8(10)

90 + 4 = 14 + 80

94 = 94

By doing those steps we can confirm the answer, e = 10, is true.

8 - 4a = -2a


7th Grade Linear Questions

Answers

Add 4a to both sides:
8 = 2a
Divide both sides by 2:
a = 8/2
a = 4

Answer:

a = 4

Step-by-step explanation:

So your goal here is to get the variable on just one side, so add 4a to both sides.  This cancels out the 4a on of of the sides and puts a on the other side.  The new equation is 8 = -2a + 4a.  Combine like terms to get 8 = 2a.  Divide both sides by 2 to get a = 4.    You can check your work by replacing a with 4:  

8 - 4(4) = -2(4)

8 - 16 = -8

-8 = -8

Since the final result is true, (-8 does equal -8,) a = 4.  

what is the distance from L to M?

C. 2 units
D. 10 units

Answers

The anwser is 14 units

Answer:

D. 10 units

Step-by-step explanation:

Using the distance formula:

d = √(x2 – x1)² + (y2 – y1)²

Plug in the values of the points:

d = √(3 – (-5))² + (-2 – 4)²

d = √(8)² + (-6)²

d = √64 + 36

d = √100

In a multi-paragraph essay, explain his or her achievements and historical importance.Here is what I've written, I'm just having trouble with the conclusion :| Harriet Tubman was an African-American slave and a hero. Harriet was born a slave in a plantation in Dorchester County, Maryland, where she was mistreated and abused with violence that caused permanent injuries. At age twenty, Harriet Tubman escaped at night guided by the North star and traveled many miles all the way to Pennsylvania, where slavery was illegal. Harriet Tubman then served as the "conductor" for the underground railroad. The Underground Railroad was a network of secret routes and safe houses established in the US which was used by African-American slaves. This network was used to help many African-American slaves escape safely. Harriet helped many slaves escape for eleven years, going back to Maryland risking her own freedom. In 1850, the Fugitive Slave Law was passed in the US which stated that escaped slaves could be captured in the North and returned to slavery, thus Harriet changed the routes to go to Canada.
