Answer:
b. 4.4 hours
Step-by-step explanation:
We can use the conversion factor 1 mi/h = 22/15 ft/s. The required relation is ...
time = distance/speed
[tex]\dfrac{30\text{ mi}}{\left(\dfrac{150\text{ ft}}{15\text{ s}}\right)}\times\dfrac{\left(\dfrac{22\text{ ft}}{15\text{ s}}\right)}{\left(\dfrac{1\text{ mi}}{1\text{ h}}\right)}=\dfrac{(30)(22)\text{\h}}{150}\text{ h}=4.4\text{ h}[/tex]
Assuming Kyle can keep up the pace for that distance, it would take him 4.4 hours to run 30 miles.

If there are 2.2 pounds in 1 Kilogram, how many pounds are there in x kilograms?
A)2.2x
B)2.2/x
C)x/2.2
D)2.2+c
Answer:
The answer is A
Step-by-step explanation:
If there are 2.2 in 1 kilogram and you are trying to find out how many are in many kilograms then you multiply.
Hopefully this helps you :)
pls mark brainlest ;)
The expression that represents the pound of weight in x kilogram can be written as 2.2x, where x represents the weight in kilograms.
What is Units conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
As it is given that there are 2.2 pounds in 1 Kilogram. Therefore, the expression that represents the pound of weight in x kilogram can be written as 2.2x, where x represents the weight in kilograms.

Hillary’s summer job at the frozen yogurt shop paid her the amounts shown in the table below in her first three days on the job (she got paid the same hourly rate every day).
Answer:
P=9.0h
Step-by-step explanation:
Divide the Paid amount by the hours worked and you'll get how much money she gained every hour which is 8.50$ And the question is telling you which of the following equations is GREATER than the amount she got paid per hour. So the answer would be P=9.0h
The required equation represents an hourly pay rate that is greater than Hillary's hourly pay rate p = 9.0h. Option D is correct.
Given,
Hillary’s summer job at the frozen yogurt shop paid her the amounts shown in the table below in her first three days on the job (she got paid the same hourly rate every day).
day = 1 2 3
Hours worked(h) = 5 4 6
Amount paid (p) = $42.50 $34 $51
The slope of the line is the tangent angle made by line with horizontal. i.e. m = tanx where x in degrees.
The slope of the data given,
m = 42.5/5
m = 8.5
the slope shows the hourly rate to get paid.
Required expression is
p = 8.5h
From the option, the slope of equations needs to compare greater the slope greater will the hourly rate.
Slope of equation A = 1/8, B =8, C = 8.5 and D = 9.0
hence, only slope D has a greater value by the existing slope of 8.5
Thus, the required equation that represents an hourly pay rate that is greater than Hillary's hourly pay rate p = 9.0h.

Answer:
x=7 Hope this helps :)
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+8+3x+6=7x
Step 1: Simplify both sides of the equation.
2x+8+3x+6=7x
(2x+3x)+(8+6)=7x(Combine Like Terms)
5x+14=7x
5x+14=7x
Step 2: Subtract 7x from both sides.
5x+14−7x=7x−7x
−2x+14=0
Step 3: Subtract 14 from both sides.
−2x+14−14=0−14
−2x=−14
Step 4: Divide both sides by -2.

Find a general term an for the sequence whose first four terms are given.
2, 4, 8, 16, ...
Answer:
an = 2·2^(n-1)
Step-by-step explanation:
There are simple tests to determine whether a sequence is arithmetic or geometric. The test for an arithmetic sequence is to check to see if the differences between terms are the same. Here the differences are 2, 4, 8, so are not the same.
The test for a geometric sequence is to check to see if the ratios of terms are the same. Here, the ratios are ...
4/2 = 2
8/4 = 2
16/8 = 2
These ratios are all the same (they are "common"), so the sequence is geometric.
The general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
Filling in the values for this sequence, we find the general term to be ...
an = 2·2^(n-1)

The midpoint of AB is M(-3,-3). If the coordinates of A are (-8,-2), what are the coordinates of B? Please explain
Step-by-step explanation:
Hey there!!!
Here,
The midpoint of AB is M(-3,-3) and coordinates of A is (-8,-2).
Now,
Using midpoint formulae,
[tex](x,y) =( \frac{x1 + x2}{2} ,\frac{y1 + y2}{2} )[/tex]
Put all values.
[tex]( - 3,- 3) = ( \frac{ - 8 + x}{2} , \frac{ - 2 + y}{2} )[/tex]
As they are equal, equating with their corresponding elements we get,
[tex] - 3 = \frac{ - 8 + x}{2} [/tex]
Simplify them.
[tex] - 6 = - 8 + x[/tex]
[tex]x = - 6 + 8[/tex]
Therefore, x= 2
Now,
[tex] - 3 = \frac{ - 2 + y}{2} [/tex]
Simplify them.
[tex] - 6 = - 2 + y[/tex]
[tex]y = - 6 + 2[/tex]
Therefore, y = -4.
Therefore, the coordinates of B are (2,-4).

Please help me. 50 point question
Step-by-step explanation:
Hey there!!!!
Given,
Angle r and angle s are supplementary angle.
And angle r = 120°.
Now, we have,
supplementary angle's sum is always 180°.
So, angle r + angle s = 180°.
or, 120°+ angle s = 180°
Therefore the measure of angle s is 60°.

Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, what is Stephanie's age?
Answer: Stephanie is 15
Step-by-step explanation:
because you can do 24 divided by 2 which equals 12 then add three to 12 and you get 15.
you're welcome! plz lmk if i'm wrong XD
Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, then Stephanie's age is 15 years.
To find Stephanie's age, we need to follow the given information that her age is 3 years greater than half of her sister's current age.
First, we find half of her sister's age: Half of 24 = 24 / 2 = 12
Next, we add 3 years to half of her sister's age: 12 + 3 = 15
Therefore, Stephanie's age is 15 years.
Age can be used in mathematical equations and word problems to solve for unknowns or to establish relationships between different quantities.
