The ratio of math teachers to choir teachers is 3:2 respectively. There are 12 math teachers. How many math and choir teachers are there all together?
Answer:
Hi liddywiddy, sorry you had to wait so long
There are 20 teachers in all
Step-by-step explanation:
the ratio 3:2 is now 12:x
12 / 3 = 4
so the multiplier is 4
now:
4x2 = 8
Next we add them: 12+ 8 = 20
Answer:
20 teachers in all
Step-by-step explanation:
12 / 3 = 4,
4 * 2 = 8,
so 12 + 8 = 20

If an investment account starts with $3,900, and grows with 2.1% interest, compounded annually, how much is the account worth after 15 years?
Round your answer to the nearest dollar.
Do NOT round until you have calculated the final answer.
Answer 5327
Answer:
$5327
Step-by-step explanation:
Use the formula for calculating compound interest
A(t)=P(1+r/n)^n⋅t,
where A(t) is the balance of the account, P is the principal, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded each year, and t is the time (in years). We are given that P=$3,900, r=0.021, n=1, and t=15. Substituting the values into the formula and using a calculator to evaluate, we find
A(t)=P(1+r/n)^n⋅t = $3,900(1+0.0211)^(15)(1) ≈ $5,326.61
So the final answer is $5,327.
Answer: 5327
Step-by-step explanation:
Use the formula for calculating compound interest
A(t)=P(1+rn)n⋅t,
where A(t) is the balance of the account, P is the principal, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded each year, and t is the time (in years). We are given that P=$3,900, r=0.021, n=1, and t=15. Substituting the values into the formula and using a calculator to evaluate, we find
A(t)=P(1+rn)n⋅t=$3,900(1+0.0211)(15)(1)≈$5,326.61
So the final answer is $5,327.

Step-by-step explanation:
Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
20, 10, 5, ...
Answer:
geometric, with a common ratio of 1/2
Step-by-step explanation:
The sequence is geometric because you get successive trems by multiplying the previous term by a certain constant, the 'common ratio'. (If you got each successive term by adding or subtracting the same constant number each time, that would be an arithmetic sequence.)
In this case, it looks like you get each successive term when you multiply the previous term by 1/2.
Thus, the common ratio is 1/2.

solve the systems of equations y=2x and y=-x - 6
Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4

You roll a fair six-sided die. The die shows a three or a five.
Answer:
b) 0.333
Step-by-step explanation:
there are 6 options that you can get when you roll a dice. 1, 2, 3, 4, 5, 6. if you want to get a 3 or a 5, that means you want 2/6 possible outcomes. 2/6 is 0.333

Imagine you are hanging two identical picture frames. Each frame is 28 inches wide and the wall you are hanging them on is 10 feet wide. There needs to be 8 inches of space in between the two frames. How far do the frames need to be from the left and right side of the walls in order to be centered?
Answer:
28 inchesStep-by-step explanation:
Sum of the width of the two frames and a gap between them:
28*2 + 8 = 64 inThe gaps from the left and right are equal to x:
x = (10 feet - 64 in)/2 = (120 in - 64 in)/2 = 28 inThe graph below shows the amount of money that a student has in the bank at the end of each week.
If the pattern continues, how much money, in dollars, will the student have in the bank at the end of week 11? Round your answer to the nearest whole
dollar.
Answer:
The student will have 130 dollars in the bank at the end of week 11.
Step-by-step explanation:
Pattern:
The pattern given by this graphic is that:
For each passing week, the student will have $10 more in the bank than at the end of the previous week. So, following this pattern:
At the end of 6 weeks, he will have $80.
At the end of 7 weeks, he will have $90.
At the end of 8 weeks, he will have $100.
At the end of 9 weeks, he will have $110.
At the end of 10 weeks, he will have $120.
At the end of 11 weeks, he will have $130.
The student will have 130 dollars in the bank at the end of week 11.
Six Pepperidge Farm bagels were weighed, yielding the following data (grams):
117.6
109.5
111.6
109.2
119.1
110.8
(Note: 4 ounces = 113.4 grams)
a. Assuming that the six bagels are a random sample and the weight is normally distributed, estimate the true average weight and standard deviation of the weight using maximum likelihood.
b. Again assuming a normal distribution, estimate the weight below which 95% of all bagels will have their weights. (Hint: What is the 95th percentile in terms of μ and σ? Now use the invariance principle.)
Answer:
A) Average weight = 112.97
standard deviation = 3.913
B) 119.4069
Step-by-step explanation:
A) Estimate the true average weight and standard deviation of the weight
attached below is a detailed solution
Average weight = 112.97
standard deviation = 3.913
B) Assuming a normal distribution Estimate the weight below

The arena wants to estimate the previous two month’s ticket-sale income. In total, 71,115 people attended different events at the arena. The average ticket price is around $21.15.
Estimate the arena’s ticket sale income for the previous two months by rounding the two figures before carrying out the calculation.
The estimated income for the previous two months is
Answer: $1504083
Step-by-step explanation:
Number of people that attended events at the arena = 71115
Average ticket price = $21.15
The arena’s ticket sale income for the previous two months will be:
= 71115 × $21.15
= $1504083
$1504083
Which statement correctly identifies a point on the graph of f–1(x)?
Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
Answer:
The point (4, –7) is on the graph of f(x), so the point (7, –4) will be on the graph of f–1(x). (quick answer A)

Two trains, Train A and Train B, weigh a total of 389 tons. Train A is heavier than Train B. The difference of their weights is 263 tons. What is the weight of each train? Equation 1: ____________ Equation 2: ___________ Train A weight: ________ Train B weight: ________
9514 1404 393
Answer:
A + B = 389A - B = 263A = 326 tonsB = 63 tonsStep-by-step explanation:
The first equation is an expression of the first given relationship:
A + B = 389 . . . . . . where A and B represents trains weights, respectively
The second equation is an expression of the relationship described in the next two sentences:
A - B = 263
__
These equations can be solved by adding them together:
(A +B) +(A -B) = 389 +263
2A = 652 . . . . . . simplify
A = 326 . . . . . . . .divide by 2*
B = 326 -263 = 63
Train A weighs 326 tons.
Train B weighs 63 tons.

Answer:
[tex]F = 1.8C + 32[/tex]
Step-by-step explanation:
Given
The attached table
Required
The relationship between both temperatures
This implies that we calculate the table equation
First, we calculate the slope (m)
[tex]m = \frac{F_2 - F_1}{C_2 - C_1}[/tex]
Where:
[tex](C_1,F_1) = (0,32)[/tex]
[tex](C_2,F_2) = (20,68)[/tex]
So, we have:
[tex]m = \frac{68 - 32}{20 - 0}[/tex]
[tex]m = \frac{36}{20}[/tex]
[tex]m = 1.8[/tex]
The equation is then calculated using:
[tex]F = m(C - C_1) + F_1[/tex]
This gives:
[tex]F = 1.8(C - 0) + 32[/tex]
[tex]F = 1.8(C ) + 32[/tex]
[tex]F = 1.8C + 32[/tex]
