Answer:
[tex]-4\ \text{feet/hour}[/tex]
Step-by-step explanation:
Level of water at 4 PM is 10 feet.
Level of water at 8 PM is 2 feet.
Time duration in which water level is measured is [tex]8-4=4\ \text{hours}[/tex]
The change of the level of water in the given time duration is [tex]2-10=-8\ \text{feet}[/tex]
The rate of change would be
[tex]R=\dfrac{-8}{4}=-4\ \text{feet/hour}[/tex]
The constant rate of change of the water is [tex]-4\ \text{feet/hour}[/tex].
The minus sign indicates that the water level is reducing.

A bowl contains blueberries and strawberries. There are a total of 48 berries in the bowl. The ratio of blueberries to strawberries is 9 to 3. How many of each berry are in the bowl?
A bowl contains blueberries and strawberries. There are a total of 20 berries in the bowl. The ratio of blueberries to strawberries is 4 : 1. How many of each berry are in the bowl?
Answer:
a. 36 blueberries and 12 strawberries
b. 16 blueberries and 4 strawberries
Step-by-step explanation:
The computation of each berry in the bowl is shown below;
a. Total 48 berries
The Ratio of blueberries to strawberries is 9:3
So, the blueberries is = 48 × 9 ÷ (9 + 3) = 36
And, the strawberries is = 48 × 3 ÷ (9 + 3) = 12
b. Total 20 berries
The Ratio of blueberries to strawberries is 4:1
So, the blueberries is = 20 × 4 ÷ (4 + 1) = 16
And, the strawberries is = 20 × 1 ÷ (4 + 1) = 4

what is the surface area of this rectangle prison of 6 9 4
Answer:
You need to be specific on which is the length, height and width. Making the most basic assumption I would have to assume the answer is 228
Step-by-step explanation:
Formula for the surface area of a rectangular prism is A=2(wl+hl+hw)
A = 2 x (9 x 6 + 4 x 6 + 4 x 9)
A = 2 x (54 + 24 + 36)
A = 2 (114)
A = 228

3x^2-4x-7
3x^2+3x-7x -7
Common factor from two pairs
3x^2 +3x-7x-7
3x(x+1) - 7(x+1
Rewrite in factored form
3x(x+1) - 7(x+1)
(3x-7) (x+1)

formula πr^2
Rewrite the expression in the form 6^n 6^-6/6^-5
Answer:
6^-1
Step-by-step explanation:
6^-6 - (-5) = 6^(-6 + 5) = 6^(-1)
A lot of things are going on in this question. Notice how the 5 is handled. It starts off in the denominator as - 5 and when brought to the numerator it becomes -(-5) which makes it + 5.
The answer is then easy. It is 6^(-6 + 5) = 6^-1
You could give the answer as 1/6 but that is not what the question says.

A marine biologist earns $21.75 per hour. If she works 40 hours a week for 52 weeks a year, how much could she earn after 15 years?
Answer:
Step-by-step explanation:
EARNINGS FOR YEARS = PAY RATE/HOUR * HOURS/WEEKS * WEEKS/YEAR * YEARS
EARNINGS FOR 15 YEARS = 21.75/hour * 40 hours/week * 52 weeks/year * 15 years
Earnings = $678,600

The point (17,−9) is translated to the point (6,2). Select the description of the translation.
A
9 down, 7 right.
B
11 left, 11 up
C
9 right, 11 up
D
11 left, 9 down plzzz answer..
Answer:
11 up , 11 left
Step-by-step explanation:
Given
[tex](17, -9)[/tex] to [tex](6,2)[/tex]
Required
Determine the translation rule
Considering the x coordinates.
From 17 to 6
6 is to the left of 17.
Using the translation rule:
[tex]x = x' + b[/tex]
[tex]17 = 6 + b[/tex]
[tex]17 - 6 = b[/tex]
[tex]11 = b[/tex]
[tex]b = 11[/tex]
Hence: From 17 to 6 is 11 units left translation
Considering the y coordinates.
From -9 to 2
2 is at the top -9.
Using the translation rule:
[tex]y = y' + b[/tex]
[tex]-9 = 2 + b[/tex]
[tex]-9 - 2 = b[/tex]
[tex]-11= b[/tex]
[tex]b = -11[/tex]
The negative value impies a upward translation.
Hence: From -9 to 2 is 11 units up translation

Kareem received $50 during his birthday. In addition, he saves $10 each week. Which equation can help find w, the number of weeks it will take Kareem to save a total of $200?
Answer: 50+10w=200 w=15
Step-by-step explanation:
So we know that Kareem starts off with $50 and every week he gains an additional $10 so as many weeks it takes to get $150 in addition to the $50 he already has to get $200. so $50+$10w=$200 where w represents the number of weeks it takes until the sum is 200

The amount of money that Maria had in a savings amount at the beginning of 2018 was $2,750. At the beginning of 2019, the same saving account
Complete question :
The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750. At the beginning of 2019, the same savings account now had $3,201 in it.
By what percent did Maria’s savings increase from 2018 to 2019? Show the work that leads to your answer and do not round.
Answer:
16.4%
Step-by-step explanation:
Given that:
Amount in 2018 = 2750
Amount in 2019 = 3201
Percentage increase in savings :
[(amount saved in 2019 - Amount saved in 2018) / Amount saved in 2018] * 100%
[(3201 - 2750) / 2750] * 100%
= 451 / 2750 * 100%
= 0.164 * 100%
= 16.4%

Answer:
the change in x is 1, the change in y is 4, the slope is 1/4
Step-by-step explanation:
the time increases by one minutes as the temperature increases by 4 degrees. therefore, every one minutes the temperature increases by four degrees. 1/4
Answer:
1, 4 and 4
Step-by-step explanation:
x = 10-9 = 1
y = 64-60 = 4
Rate of change = temperture / time
= 4/1
= 4.
