Step-by-step explanation:
Jada walks up to a tank of water than can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
a. At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
b. How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
c. How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answer:
a. rate to empty the tank = - 2/3 gal/min
b, 7.5 min to empty the tank
c. 4.5 min.
Step-by-step explanation:
I use the formula that the work done = rate of work times the time working = W = rt
The work in this problem is emptying the tank.
a. The rate to empty the tank is -2 gal/3 min or - 2/3 gal/min
b. 5/(2/3) = 15/2 = 7.5 min to empty the tank
c. Since 3 gal. had already drained, 3/(2/3) = 9/2 = 4.5 min.
f(x) = x ^ 2 What is g(x)?
Answer:
A ; g(x) = (1/2 x)^2
Step-by-step explanation:
Here, we want to get g(x)
we have a point on the curve g(x)
The point is represented by (2,1)
What this mean here is that, when x = 2, y = 1
Looking at the first option;
Substitute 1 for y and 2 for x
1 = (1/2 * 2)^2
1 = 1
This means this is our answer
The equation for g(x) is;
g(x) = (1/2 x)^2

Answer:
y = 7, x ≈ 9.9
Step-by-step explanation:
The remaining angle has to also be 45° which tells us we're working with an isosceles right triangle, or that y also has to be 7 (the same length).
Use the Pythagorean theorem for x.
a^2 + b^2 = x^2
7^2 + 7^2 = x^2
49 + 49 = x^2
x^2 = 98
x ≈ 9.9
Find the function h(x) = f(x) + g(x) if f(x) = 4^x + 2 and g(x) = x - 4.
h( x) = 4 x + 1 -2
h( x) = 4 x + x + 6
h( x) = 4 x - 4
h( x) = 4 x + x - 2
Answer:
h( x) = 4^x + x - 2
Step-by-step explanation:
h(x)=f(x)+g(x)=4^x+2+x-4=4^x+x-2

The range of the project will be equal to 0.82.
What is the range in statistics?When the sample maximum and minimum are subtracted, the range of a set of data is the difference between the largest and smallest values. It uses the same units as the data to express itself.
The given data of the project is,
u 0.87
v 0.31
w 0.08
x 0.05
y 0.19
z 0.5
The range will be calculated as the difference between the maximum value to the minimum value.
Range = 0.84 - 0.05
Range = 0.82
Therefore, the range of the project will be equal to 0.82.

Sally bought 4 chocolate bars and 8 lollipops and paid $8.00. Josh bought 3 chocolate bars and 10 lollipops and paid $7.00.
What is the cost of a lollipop? Enter your answer as a decimal
Answer:
Lollipops cost $0.25
Step-by-step explanation:
4C + 8L = $8.00
3C + 10L = $7.00. We need to cancel out chocolate bars
-12C - 24L = $-24.00 Mulitply by -3
12 C + 40L = $28.00 Muliply by 4 Next simplify
16L = $4.00 Divide both sides by 16
L = $0.25
WE CAN EVEN CHECK OUR WORK
4C + 8(0.25) = $8.00
4C = $6.00
C = 1.5
3(1.5) + 10(.25) = $7.00
4.5 + 2.5 = 7

Which of the following are not perfect squares? Select all that apply.
16
44
81
6
49
24
Answer and Step-by-step explanation:
44, 6, and 24 do not have perfect squares.
To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.
44, 6, and 24 can't do this when being square rooted.
16 turns into 4.
81 turns into 9.
49 turns into 7.
#teamtrees #PAW (Plant And Water)
Answer:
44, 6, and 24
Step-by-step explanation:
4²=16 so it's a perfect square
9²=81 so it's a prefect square
7²=49 so it's a perfect square
44, 6, and 24 all result in decimals so it's not a perfect square.
Triangle Congruency please help!!
Answer:
A
Step-by-step explanation:
the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.
50+ 63= 113
180-113 =67
so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure

The sales tax in one town is 8%. So, the total cost of an item can be written as c+0.08c. What is the total cost of an item that sells for 12?
Answer:
12.96c
Step-by-step explanation:
Given the total cost of an item written as c+0.08c. To get the total cost of an item that sells for 12, we will write;
1 item = c+0.08c
1 item = 1.08c
For 12items;
12 = x
Divide both expressions
1/12 = 1.08c/x
1 * x = 12 * 1.08c
x= 12.96c
Hence the total cost of 212 items is 12.96c
A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $693 on props, and 37% of the total budget on equipment. What was the total budget for their student film?
Answer:
$1100
Step-by-step explanation:
Let the total budget = b
amount spent on props + amount spent on equipment = total budget
If 37% of the budget was spent on equipment
The percentage spent on props = 100% - 37% = 63%
63% of the total budget is $693
the above sentence presented as an equation gives :
63/100 x b = 693
to find b, divide both sides of the equation by 100/63
b = $1100
Answer:
1100

the question is: find the value of x for each equation below and the numbers is
-x+3=3x-2
1.5x-3=2.25x
-1/3x+2=3x-1
Answer:
1. x=5/4
2. x=-4
3. x= 9/10
Step-by-step explanation:
Let's solve your equation step-by-step.
−x+3=3x−2
Step 1: Subtract 3x from both sides.
−x+3−3x=3x−2−3x
−4x+3=−2
Step 2: Subtract 3 from both sides.
−4x+3−3=−2−3
−4x=−5
Step 3: Divide both sides by -4.
−4x/−4 = −5/ −4
x= 5/4
Answer:
x= 5/4 (5 over 4)
Let's solve your equation step-by-step.
1.5x−3=2.25x
Step 1: Subtract 2.25x from both sides.
1.5x−3−2.25x=2.25x−2.25x
−0.75x−3=0
Step 2: Add 3 to both sides.
−0.75x−3+3=0+3
−0.75x=3
Step 3: Divide both sides by -0.75.
−0.75x/−0.75=3/−0.75
x=−4
Answer:
x=−4
Let's solve your equation step-by-step.
−1/3x+2=3x−1
Step 1: Subtract 3x from both sides.
−1/3x+2−3x=3x−1−3x
−10/3x+2=−1
Step 2: Subtract 2 from both sides.
−10/3x+2−2=−1−2
−10/3x=−3
Step 3: Multiply both sides by 3/(-10).
(3/−10)*(−10/3x)=(3/−10)*(−3)
x=9/10
Answer:
x=9/10 (9 over 10)
