Answer:
Either 30 or 32, depending on if your teacher wants you to use exact decimals, or rounded numbers
Step-by-step explanation:
Usually people round liters to equal 4 per gallon, which would give you 32.
However, a liter is technically 3.785 liters per gallon- and this exact number would give you 30 as an awnser.
I'd say 32 is the safer awnser, unless your teacher has given you the number 3.785 decimal amount to use instead.
Which number line represents the solutions to |x + 4| = 2?
Answer:
x=-2, -6 > pick the first answer choice !!!!!
Step-by-step explanation:
Let's solve your equation step-by-step.
|x+4|=2
Solve Absolute Value.
|x+4|=2
We know either x+4=2or x+4=−2
x+4=2 (Possibility 1)
x+4−4=2−4 (Subtract 4 from both sides)
x=−2
x+4=−2 (Possibility 2)
x+4−4=−2−4 (Subtract 4 from both sides)
x=−6
Answer:
x=−2 or x=−6

Let X and Y be the following sets: X = {0, 12, 23} Y = {3, 12, 15) Which of the following is the set X/Y?
Answer:
set X/Y = {0,23}
Step-by-step explanation:
We are given the sets;
X = {0, 12, 23}
Y = {3, 12, 15}
Now, we want to find the set X/Y.
The set X/Y means the set that has numbers which are only in set X but not in set Y.
The numbers from inspection of both sets are 0 and 23.
Thus;
set X/Y = {0,23}

Liam plays guitar in a band called Cool. The
band is paid $421.74 for every performance. If
Cool averages 3.5 shows per month, how much
money will the band earn in 3 months?
Answer: $4,428.27
Step-by-step explanation:
First you have to find out how many shows are in three months. If there is 3.5 shows in one month, multiply this by three to get the amount in 3 months.
3.5 x 3 = 10.5 shows
Now multiply the amount the band makes in one show by the number of shows.
$421.74 x 10.5 shows = $4,428.27 over the course of three months.
Hope this helps!

Which is the largest interval over which the function in the table is increasing?
Answer:
Solution given:
y=-1/2 x²
for
f(x)=-1/2 x².
differentiating each term with respect to x
f'(x)=-x
when
x=-4
f'(-4)=4>0 increasing
when
x=-2
f'(-2)=2 >0 increasing
when x=0
f'(0)=0 stationary point.
other points are decreasing
so
largest interval of increasing is

An emergency fund is defined as a savings account that has a balance equal to at least two months' living
expenses. An article in a financial magazine claims that 80% of American adults do not have an emergency fund.
To investigate this claim, a financial advisor selects a random sample of 150 American adults and finds that 112 do
not have an emergency fund. The financial advisor would like to know if the data provide convincing evidence that
the true proportion of Americans who do not have an emergency fund is less than 80%. What are the appropriate
hypotheses for this test?
Answer:
a H I o p=0.80 vs. Ha less than 0.80, where P equals the true proportion of All American adults who do not have an emergency fund
The appropriate hypotheses for this test are:
H0: p ≥ 0.80
Ha: p < 0.80
We have,
The appropriate hypotheses for this test are:
Null Hypothesis (H0):
The true proportion of Americans who do not have an emergency fund is equal to or greater than 80%.
Alternative Hypothesis (Ha):
The true proportion of Americans who do not have an emergency fund is less than 80%.
Symbolically, the hypotheses can be represented as:
H0: p ≥ 0.80
Ha: p < 0.80
Where p is the true proportion of American adults who do not have an emergency fund.
To determine whether the data provide convincing evidence against the null hypothesis,
We can conduct a hypothesis test using a significance level (alpha) of 0.05.
If the p-value is less than alpha, we can reject the null hypothesis and conclude that the true proportion of Americans who do not have an emergency fund is less than 80%.
Thus,
H0: p ≥ 0.80
Ha: p < 0.80 are the appropriate hypotheses for this test.

A water tank holds 24,000 gallons. How many ours will it take for 2/3 of water to be used if the water if the water is used at an average rate of 650 gallons per day
Answer: 591 hours
Step-by-step explanation:
First find out what 2/3 of the water is:
= 2/3 * 24,000
= 16,000 gallons
650 gallons are used per day so the time it takes in days to use the above is:
= 16,000 / 650
= 24.62 days
There are 24 hours in a day. The amount of time it will take to use this amount of water in hours is:
= 24.62 * 24
= 590.88
= 591 hours

Alright, so first we should add up all of the teachers to get the gist of how many there are in each school.
I got 50 in both North MS and West MS.
F. Half of the teachers would be 25. music+cooking=25 teachers. Correct.
But now, we need to find percentages.
Convert the problem to an equation using the percentage formula: P% * X = Y.
30%x50= 15. Does 9+6 equal 15? Yes, F is Correct.
G. A quarter of 50 is 12.5. (There can't be decimals of teachers though.) At West MS 11 teachers enjoy reading and 14 enjoy outdoor recreation. 11 is less than 12.5 and 14 is more. Incorrect.
H. A majority means more than half in simple terms. Do more than half of the teachers at North MS enjoy rec and cooking? (6+19) It's tricky as there's 25 teachers. However, it is not greater than 25 so it is not a majority. Incorrect.
J. Less than half of 50 teachers at West MS enjoy rec and music. (14+15=29)
Incorrect.
Hope this helped! Khan Academy is a fantastic resource.
Answer:
F.) Half of the teachers at West MS enjoy cooking and music, while only 30% of the teachers at North MS enjoy cooking and music.
Step-by-step explanation:
NORTH MS → TOTAL: 50 TEACHERS
R:16 C:6 OR:19 M:9 → R:32% C:12% OR:38% M:18%
WEST MS → TOTAL: 50 TEACHERS
R:11 C:10 OR:14 M:15 → R:22% C:20% OR:28% M:30%
F.)
Half of the teachers at West MS enjoy cooking and music ✓
30% of North MS enjoy cooking and music ✓
This statement is TRUE.
G.)
Over a quarter of West MS teachers enjoy reading
Less than a quarter of West MS teachers enjoy outdoor recreation
This statement is FALSE.
H.)
The majority of teachers at North MS enjoy outdoor recreation and cooking
This statement is FALSE.
J.)
Less than half of West MS teachers enjoy outdoor recreation and music
This statement is FALSE.

A small school bus holds 26 students. A larger school bus holds 150% as many students as the small school bus. How many students does the larger school bus hold?
Please help :/
Answer:
39
Step-by-step explanation:
To solve this problem we can use a proportion:
150 : 100 = x : 26
x = (26*150)/100 = 39
Answer:
39
Step-by-step explanation:
150% of 26 is 39
on a calculator do 26 times 150% and it equally 39
another way to do it is do 26 divided by 2 which equals 13, then add 13 to 26 and you get 39
The diagram shows a field ABC.
AC = 240 m
Use the sine rule to calculate AB.
Answer:
AB ≈ 312.1 m
Step-by-step explanation:
Using the Sine rule in the triangle, then
[tex]\frac{AB}{sin85}[/tex] = [tex]\frac{240}{sin50}[/tex] ( cross- multiply )
AB × sin50° = 240 × sin85° ( divide both sides by sin50° )
AB = [tex]\frac{240sin85}{sin50}[/tex] ≈ 312.1 m ( to 1 dec. place )
What are the values of x and y, in the given figure?
I'll give brailiest to the first response
Answer:
y = 52
x = 5
Step-by-step explanation:
Side BC and Side BA are congruent sides ( indicated by the two dashed lines. )
This meaning that their opposite angles are also congruent
Side BC's opposite angle is ∠A and side BA's opposite angle is ∠C
Hence ∠A ≅ ∠C
And because ∠A = 52°, ∠C also equals 52°
Hence y = 52°
Now we want to find x
We can do this by creating an equation using the triangle angle rule which states that the angles in a triangle add up to equal 180
so...
180 = 14x + 6 + 52 + 52
now we solve for x
step 1 combine like terms
52 + 52 + 6 = 110
now we have 180 = 110 + 14x
step 2 subtract 110 from each side
180 - 110 = 70
110 - 110 cancels out
now we have 70 = 14x
step 3 divide each side by 14
14x/14 = x
70 / 14 = 5
we're left with x = 5

Answer:
The larger number is 37 and the smaller number is 14.
Step-by-step explanation:
Let's solve this problem in terms of x and y:
x+y=60
x-y=14
x will be the larger number while y will be the smaller number.
When we add both those equations together, we get 2x=74 since y-y=0. Now we do 74÷2 which equals 37 so x=37. Finally we know that x=37 so our y must be the remaining part since x+y=60. We simply subtract 37 from 60 and get our smaller number, 23.

Find the surface area of the cone. Round your answer to the nearest tenth!!
GIVING BRAINLIEST
Formula:
Shape = Cone
Radius (R) = 1
Height (H) = 4
Formula of surface area (cone) = A=πr(r+h2+r2)
How to find a surface area of a cone?
Using the formula of the cone (A=πrl+πr2) We add the formula so the radius and the height (l=r2+h2). Since we are solving for a our formula will end up looking like (A=πr(r+h2+r2)=π·1·(1+42+12)≈16.09471). Which will equal our answer which is 16.09471. Round to the nearest tenth will be 16.09.
