Answer:
[tex]g(t)=8.25t+1250[/tex]
Step-by-step explanation:
You can input any value for t, and that would give you the amount of water pumped in. Then, the +1250 represents the initial 1250 gallons that are in the pool.
Customers of a utility company received notices in their monthly bills that heating costs for the average customer had increased 125% over last year because of an unusually severe winter. In January of last year, the Garcia's paid $120 for heating. What should they expect to pay this January if their bill increased by 125%?
Answer: $270
Step-by-step explanation:
Cost of heating last year = $120
The amount that they will expect to pay this January if their bill increased by 125% will be the addition of $120 and 125% of $120. This can be mathematically expressed as:
= $120 + (125% × $120)
= $120 + (1.25 × $120)
= $120 + $150
= $270

A contractor purchases ceramic tile to remodel a kitchen floor. Each tile costs $4.00, and the adhesive and grouting material needed for the whole job costs $15.82. The contractor is charged a total of $655.82, how many ceramic tiles did the contractor purchase?
Answer:
160 tiles.
Step-by-step explanation:
First let's make an equation.
Each tile costs $4, let's make t=number of tiles.
+$15.82, and the total cost being $655.82
So ideally our equation would look like
4t+15.82=655.82
Now solve.
First, subtract 15.82 on both sides.
4t=640
Second, divide 4 on both sides to make the variable t by itself.
t=160
So, the contractor purchased 160 tiles.
In 1819, the United States purchased Florida from Spain for
$5 X 106. The area of Florida is about 6.6 x 104 square miles.
Which key strokes on a calculator will give the cost the
United States paid for each square mile of Florida?
A) 6.6EE4×5EE(-)6
B) 6.6EE4÷5EE6
C)5EE6×6.6EE4
D)5EE6÷6.6EE4
Answer:
D. 5 x 10⁶ ÷ 6.6 x 10⁴Step-by-step explanation:
If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;
6.6 x 10^4 mi² = $5 X 10^6
1mi² = $x
Cross multiply;
$5 X 10^6 * 1 = 6.6 x 10^4 * x
6.6 x 10⁴ x = 5 X 10⁶
Divide both sides by 6.6 x 10⁴ to get x;
6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴
x = 5 x 10⁶ ÷ 6.6 x 10⁴
x = 0.76*10⁶⁻⁴
x = $0.76*10²
Hence the key strokes on a calculator will give the cost the United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

The given trig function consist of trig values of common angles;
The values that represent the solution to [tex]\mathbf{cos \left(\dfrac{\pi}{4} - x\right)} = \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex], x ∈ [0, 2·π) are;
[tex]x = \left\{\dfrac{\pi}{2} , \, or \ \dfrac{3 \cdot \pi}{2} \right \}[/tex]
Reason:
The given function is presented as follows;
[tex]cos \left(\dfrac{\pi}{4} - x\right) = \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex]
Where;
x ∈ [0, 2·π)
We have;
cos(A - B) = cos(A)·cos(B) - sin(A)·sin(B)
[tex]cos \left(\dfrac{\pi}{4} \right) = \dfrac{\sqrt{2} }{2}, \ sin\left(\dfrac{\pi}{4} \right) = \dfrac{\sqrt{2} }{2}[/tex]
Which gives
[tex]cos \left(\dfrac{\pi}{4} - x\right) =\dfrac{\sqrt{2} }{2} \cdot cos \, x + \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex]
Therefore, we get;
[tex]\dfrac{\sqrt{2} }{2} \cdot cos \, x = \dfrac{\sqrt{2} }{2} \cdot sin \, x - \dfrac{\sqrt{2} }{2} \cdot sin \, x = 0[/tex]
cos x = 0
[tex]cos \left(\dfrac{\pi}{2} \right) = 0[/tex]Therefore;
The possible solutions (x-values) to cos x = 0 are; [tex]0 \leq \dfrac{n \cdot \pi}{2} \leq 2 \cdot \pi[/tex]Where;
n = 1, 3, 5, ...
x ∈ [0, 2·π)
We get;
[tex]x = \left\{\dfrac{\pi}{2} , \, or \ \dfrac{3 \cdot \pi}{2} \right \}[/tex]Learn more here:

What is the simplest form of 4a + 8b/12
Step by step pls
Answer:
4a + 2b/3
Step-by-step explanation:
focus on 8b/12 first:
factor 8b/12 by 4 ---> 8b/12 = 4(2)b/4(3) ----> cancel 4 in the denominator and the nominator ---> 8b/12 = 4(2)b/4(3) = 2b/3
then, go back to 4a:
4a is in its simplest form, it can't be factor
therefore, plus 4a and 2b/3 = 4a + 2b/3

Gianna paid $4.75 for a strawberry smoothie. She now has $12.35. How much money did Gianna have before she bought the smoothie? Select all that apply. m - 4.75 = 12.35 A. Add 4.75 to both sides of the equation. B. Subtract 4.75 from both sides of the equation. C. 12.35 + 4.75 = 17.10. D. 12.35 - 4.75 = 7.60. E. Gianna had $7.60 before she bought the smoothie. There is more than one answer.
Answer:
Add 4.75 to both sides of the equation.
Step-by-step explanation:
using the notation from the options in the answer, say the money that Gianna had was m
And she paid $4.75 for a strawberry smoothie.
then we can calculate the money she had by subtracting the $4.75 paid for a strawberry smoothie from m and equating it to her the balance she has currently
so mathematically
m-4.75=12.34
Add 4.75 to both sides of the equation we have
m-4.75+4.75=12.34+4.75
m=$17.09
The correct answer is
Gianna had $17.09 before she bought the smoothie
Answer:
A. add 4.75 to both sides of the equation.
C. 12.35 + 4.75 = 17.10

If the weather forecast calls for a 20% chance of light rain tomorrow, would you say that it is likely to rain tomorrow?
Answer:
Unlikely
Step-by-step explanation:
There are more chances that tomorrow there will be no rain than the raining we can say that it is unlikely to rain tomorrow.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
The weather forecast calls for a 20% chance of light rain tomorrow.
Probability of rain:
P(rain) = 20% = 0.2
Complement event: Not rain tomorrow
Probability of complement event P(not rain) = 1 – 0.2 = 0.8 or 80%
P(not rain) > P(rain)
Thus, there are more chances that tomorrow there will be no rain than the raining we can say that it is unlikely to rain tomorrow.
