Sierra’s ice cream shop made $45 before she had to close early when the power went out. She realized she lost Two-thirds of a dollar each hour when the shop was closed. The expression that models this situation is 45 minus two-thirds h. What was Sierra’s profit if the shop was closed for 6 hours?
Answer:
Sierra's profit was $41.
Step-by-step explanation:
Sierra realized she lost two-third of a dollar each hour when the shop was closed.
The expression that models this situation is, ............. (1)
Now, we have to calculate Sierra's profit if the shop was closed for 6 hours.
So, putting h = 6 hours in the equation (1) we get,
dollars.
So, Sierra's profit was $41. (Answer)

Look at the following numbers:
-7, 0, 7, 14
Which pair of numbers has a sum of 0?
Group of answer choices
0, 7
-7, 7
7, 14
-7, 14
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
Your answer is B.) -7, 7

Please help me with my homework please.
Answer:
a) Speed of the cyclist is (2.75/0.4) = 6.875 miles per hour.
b) It will take (5.5/6.875) = 0.8 hours to travel 5.5 miles at this rate.
Remember: Speed=Distance/TimeA bus travels 300 kilometers at a given speed. If the speed is increased by 5 kilometers per hour, the trip will be reduced by two hours. Find the speed.
Answer:
25km/hr (take the word train as bus )
Step-by-step explanation:
Answer
Let x km/hr be the constant speed of the train,
Then Time taken to cover 300km=
x
300
hrs
Time taken to cover 300km when the speed is increased by 5km/hr=
x+5
300
hours
It is given that the time to cover 300km is reduced by 2 hours
∴
x
300
−
x+5
300
=2
⇒
x(x+5)
300(x+5)−300x
=2⇒2x

+5x−750=0⇒x
2
+30x−25x−750=0
⇒(x+30)(x−25)=0⇒x=25orx=−30
But x cannot be negative. Therefore x=25
Hence, the original speed of the train is 25km/hr

Answer:
x > - 4
Step-by-step explanation:
Given
x > [tex]\frac{5x-12}{8}[/tex]
Multiply both sides by 8 to clear the fraction
8x > 5x - 12 ( subtract 5x from both sides )
3x > - 12 ( divide both sides by 3 )
x > - 4

At 8:00 A.M., the temperature is 53 °F. At 11:00 A.M., it is 69 °F.
What is the average change in temperature per hour?
5.33 F is the average change in temperature per hour.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given, At 8:00 A.M., the temperature is 53 °F. At 11:00 A.M., it is 69 °F.
Since there is a Sum change in temperature in 3 hours
From the formula of average:
Average change = total change/ time taken
in our case
Total change = 69 - 53
Total change = 16 F
Total time taken = 11 - 8
Total time taken = 3
Thus Average = 16/3
Average = 5.3333
Therefore, the average change in temperature per hour is 5.33 F.

find the volume of a cone with diameter of 12m and a height of 7m
Answer:
A) [tex]84\pi[/tex] or approximately [tex]263.76[/tex] cubic meters
Step-by-step explanation:
The formula for finding the volume of a cone is [tex]V=\frac{1}{3}\pi r^{2} h[/tex] where [tex]V[/tex], [tex]r[/tex], and [tex]h[/tex] are the cone's volume, radius, and height, respectively. We are given that we need to solve for the cone's volume, and we are also given the cone's height, but we don't know its radius. Not to worry though because we are given its diameter, and since radius is simply half of the diameter, we know that the cone's radius is [tex]\frac{12}{2}=6[/tex] m. Now, we know that [tex]r=6[/tex] and [tex]h=7[/tex], so plugging these values into the equation, we get:
[tex]V=\frac{1}{3}\pi r^{2} h[/tex]
[tex]= \frac{1}{3} \pi *6^{2} *7[/tex] (Substitute given values into equation)
[tex]=\frac{1}{3}\pi *36*7\\=84\pi[/tex] (Simplify)
Since [tex]\pi[/tex] is approximately [tex]3.14[/tex], we know that [tex]84\pi =84*3.14=263.76[/tex]. Therefore, the volume of the cone is [tex]84\pi[/tex] or approximately [tex]263.76[/tex] cubic meters. Hope this helps!

w^2+13w+36=(w+4)(w+?)
Answer:
w1= -8, w2 = -4
Step-by-step explanation:
Answer: [tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]
Step-by-step explanation:
[tex]w^{2} + 13w + 36 = (w + 4)(w + ?)[/tex]
w (w + ?) +4 (w + ?)
w² + ?w + 4w + ?
4w + ?w = 13w
Subtract both sides by 4w
?w = 9w
? = 9
4 (?) = 36
Divide both sides by 4
? = 9
[tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]

Solve the equation,
9b + 15 = 4b = 10
Answer:
b=-1
Step-by-step explanation:
First step to any algebraic equation is to combine like-terms. This would mean that we would have to subtract 4b from both sides, I'm assuming its supposed to be plus ten and you just typed it wrong but, we get 5b+15=10 here we subtract 15 from both sides and get 5b=-5. Now we isolate the variable b, getting b=-1.

AB =
Answer:
[tex]AB= \frac{97}{3}[/tex]
Step-by-step explanation:
Properties of Rhombus
All sides of the rhombus are equal. The opposite sides of a rhombus are parallel. Opposite angles of a rhombus are equal. In a rhombus, diagonals bisect each other at right angles. Diagonals bisect the angles of a rhombus.We are given two sides of the rhombus BC and CD. According to the first property:
4x + 15 = 7x + 2
Subtracting 4x:
15 = 3x + 2
Subtracting 2:
13 = 3x
Dividing by 3:
[tex]x=\frac{13}{3}[/tex]
It's required to find the side AB. Applying the first property again:
AB= BC = CD = 4x + 15
[tex]AB =4*\frac{13}{3}+15[/tex]
[tex]AB= \frac{52}{3}+15[/tex]
[tex]AB= \frac{97}{3}[/tex]

Answer:
[tex]x=54.6[/tex]
Step-by-step explanation:
Because ΔABC is similar to ΔSTU, we know that their corresponding sides are proportional. Therefore, we know that [tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]. We are given that [tex]AB=x[/tex], [tex]AC=21[/tex], [tex]SU=13[/tex], and [tex]ST=5[/tex]. After substituting the given values into the proportion and solving for [tex]x[/tex], we get:
[tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]
[tex]\frac{x}{21} =\frac{13}{5}[/tex] (Substitute given values into the proportion)
[tex]5*x=13*21[/tex] (Cross-Products Property)
[tex]5x=273[/tex] (Simplify)
[tex]\frac{5x}{5}=\frac{273}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=54.6[/tex] (Simplify)

Complete the equation to show how many thirds are equivalent to
8/12 = ?/3
Answer:
[tex]\frac{2}{3}[/tex]
Explanation:
What we need to do is to convert [tex]\frac{8}{12}[/tex] into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.
We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of [tex]\frac{8}{12}[/tex] - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.
So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is [tex]\frac{2}{3}[/tex].
