"A water tank holds 24,000 gallons. How many days will it take for all of the water to
be used if the water is used at an average rate of 650 gallons per day? (round to the
nearest whole number)"
a) y =
X +
b)
days
Answer:
a) y=650x+0
b) 24,000=650x
24,000/650=x
x=37
I hope this is good enough:
if you can you don't have to put the +0 its just to fill it all out

20% of the total candy in a basket is Reese's chocolate. There are 8 Reese's in the basket. What is the total number of pieces of candy in the basket?
Answer:
I believe it is 40. I'm not 100% sure though
Step-by-step explanation:
If 20% of the candy is reese's and there are 8 reese's in the basket, to find the answer you must multiply 8 by 5. You multiply 8 by 5 because to get 100% you have to multiply 20% by 5 to get 100%.
Solve as y=mx+b
Write an equation of the line below.
Answer:
y = 2x
Step-by-step explanation:
Since the line passes through the origin or (0,0), adding + 0 is irrelevant so we are just looking for slope.
Since there is a rise of 2 units every one unit, the slope or m = 2.
Since we know two points by observing the graph (0,0) and (3,6). m = y2-y1/x2-x1 = 6-0/3-0 = 6/3 = 2/1 = 2

11. A large pine tree was struck by lightning and fell as
shown by the diagram below. Which equation
could be used to find the length of the fallen part of
the tree?
8 ft
13 ft —
A. 82 +132 - X
B. N82+132 -
C. 132 - 82 = X
D. V132 - 82 - *
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
The equation to find the length of the fallen part of the tree is
[tex]x=\sqrt{8^2+13^2}[/tex]
Right Triangle.
Right triangles is a triangle with one angle is 90 degree.
The side opposite to 90 degree is the hypotenuse.
Pythagorean Theoremthe sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .
The length of the fallen part of the tree is the hypotenuse
Hypotenuse is 'x'
Base of the triangle is 13 feet and height is 8 ft
Apply Pythagorean theorem to find out the hypotenuse 'x'
[tex]hypotenuse^2= base^2 + height ^2\\x^2=\sqrt{13^2+8^2} \\x=\sqrt{13^2+8^2}[/tex]
the equation to find the length of the fallen part is
[tex]x=\sqrt{8^2+13^2}[/tex]

Gerald and his dog Spike get on the scale together. Their combined weight is 128 pounds. If the ratio of Gerald's weight to Spike's weight is 3:1, how much does Gerald weigh?
Answer:
96lbs
Step-by-step explanation:
g + s = 128
g = 3s
3s + s = 4s = 128
s = 128/4 = 32
g = 3s = 96

Factor completely x3 – 3x2 - 9x + 27
Answer:

= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)

Factor this expression into primes.
22x
The factors of expression into prime numbers is 2 and 11.
We are given that;
The expression= 22x
Now,
Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
To factor an expression into primes, we need to find the prime factors of each term and then write the expression as a product of those factors.
For example, 22x can be written as:
[tex]$22x = 2 \times 11 \times x$[/tex]
The prime factors of 22 are 2 and 11, and x is already a prime factor.
Therefore, by factorization answer will be 2 and 11.

Step-by-step explanation:
Brianna invested $990 in an account paying an interest rate of 9 3 4 9 4 3 % compounded continuously. Penelope invested $990 in an account paying an interest rate of 9 1 2 9 2 1 % compounded monthly. After 16 years, how much more money would Brianna have in her account than Penelope, to the nearest dollar?
Answer:
Brianna would have $177 more in her account than Penelope after 16 years.
Step-by-step explanation:
Note: There are errors in the question especially in how the interest rates are stated. These are therefore fixed before answering the question. The complete question with the fixed errors is given as follows:
Brianna invested $990 in an account paying an interest rate of 9.34943% compounded continuously. Penelope invested $990 in an account paying an interest rate of 9.12921% compounded monthly. After 16 years, how much more money would Brianna have in her account than Penelope, to the nearest dollar?
The explanation to the answers is now provided as follows:
Step 1: Calculation of the amount of money Brianna would have in her account after 16 years
Since the interest rate is compounded continuously, the amount can be calculated using the formula for calculating the future of value (FV) with a continuous compounding interest rate as follows:
FVB = Pe^(rt) …………………………. (1)
Where;
FVB = Future value or the amount of money Brianna would have in her account after 16 years = ?
P = Amount invested = $990
e = exponential function
r = interest rate = 9.34943%, or 0.0934943
t = number of years = 16
Substituting the values into equation (1), we have:
FVB = $990 * e^(0.0934943 * 16)
FVB = $990 * e^(1.4959088)
FVB = $990 * 4.46339103998695
FVB = $4,418.75712958708
Rounding to the nearest dollar, we have:
FVB = $4,419
Therefore, Brianna would have $4,419 in her account after 16 years.
Step 2: Calculation of the amount of money Penelope would have in her account after 16 years
Since the interest rate is compounded monthly, the amount is calculated using the normal formula for calculating the future value as follows:
FVP = P * (1 + R)^n …………………………. (2)
Where;
FVP = Future value or the amount of money Penelope would have in her account after 16 years = ?
P = Amount invested = $990
R = monthly interest rate = Interest rate / 12 months = 9.12921% / 12 = 0.0912921 / 12 = 0.007607675
t = number of months = number of years * 12 months = 16 * 12 = 192
Substituting the values into equation (2), we have:
FVP = $990 * (1 + 0.007607675)^192
FVP = $990 * 1.007607675^192
FVP = $990 * 4.28510670976906
FVP = $4,242.25564267137
Rounding to the nearest dollar, we have:
FVP = $4,242
Therefore, Penelope would have $4,242 in her account after 16 years.
Step 3: Calculation of the amount of money Brianna would have more in her account than Penelope after 16 years
From Step 1 above, we have:
FVB = Future value or the amount of money Brianna would have in her account after 16 years = $4,419
From Step 2 above, we have:
FVP = Future value or the amount of money Penelope would have in her account after 16 years = $2,242
The amount of money Brianna would have more in her account than Penelope after 16 years can be calculated by deducting FVP from FVB to obtain the difference as follows:
Difference = FVB - FVP = $4,419 - $4,242 = $177
Therefore, Brianna would have $177 more in her account than Penelope after 16 years.

Write 0.25x+1y=12 in slope-intercept form.
Answer:
y = -.25x + 12
Step-by-step explanation:
Subtract x on both sides.
y = -.25x + 12
There is your answer. The "1" before the y doesn't need to be written, as a rule in algebra, ones do need to be written and are assumed to be there if there is no number at all.
-.25 is the slope and 12 is the y-intercept.

Is PRB congruent to QSB? Justify your answer.
This problem requires you to show your work and explain your reasoning.
Be sure to -
• Mark given information on the diagram
• Answer the question
• Provide justification statements that are mathematically correct
Answer:
When looking at this model, and asking yourself the question, is PRB congruent to QSB? PRB is in fact congruent to QSB. Congruent means that two figures have the same shape/size, no matter if it's mirrioring or not it is congruent. In this image, PRB is one shape, and QSB is another. They have the exact same points and they're also the same shape, but one is flipped the right side up. It was also stated PQ and RS bisect eachother at point B, <p is congruent to <Q, and <R is congruent to <S proving all these connections make this figure conguent.

Angle R is 130
Angle S is 60
Quadrilatural's angles add up to 360

In my opinion angle U looks like a right angle so 90 degrees.
170 - 90 = 80
