The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Jerome hiked 3/4 of a mile in 2/3 of an hour.
Now,
Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.
Hence, We can formulate;
⇒ Speed = Distance / Time
⇒ Speed = 3/4 / 2/3
⇒ Speed = 3×3 / 4×4
⇒ Speed = 9/16 miles per hour
Thus, The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour

Camila is competing in a 26-mile race. She runs at a constant speed of 12.5 mi/h. Write an equation in slope intercept form to represent
the distance Camila has left to run after x hours. How many hours will it take her to finish the race?
Answer:
2.08 or 2
Step-by-step explanation:
26 = 12.5x
y=mx+b
it will approximately take 2 hours, but to be exact, 2.08

You are ordering shirts for the math club at your school. Short-sleeved shirts cost $10 each. Long-sleeved shirts cost $12 each. You have a budget of $300 for the shirts. The equation 10x+12y=300 models the total cost, where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.
Question:
a. Graph the equation.
b. Twelve students decide they want short-sleeved shirts. How many long-sleeved shirts can you order.
Answer:
See attachment for graph
12 long-sleeved shirts
Step-by-step explanation:
Given
[tex]10x + 12y = 300[/tex]
Plotting the graph:
Set x = 0
[tex]10(0) + 12y = 300[/tex]
[tex]12y = 300[/tex]
[tex]y = 300/12[/tex] --- divide through by 12
[tex]y = 25[/tex]
Set x = 0
[tex]10x + 12(0) = 300[/tex]
[tex]10x = 300[/tex]
[tex]x = 300/10[/tex] --- divide through by 10
[tex]x = 30[/tex]
So, the graph will be plotted using: (0, 25) and (30, 0)
See attachment for graph
Determine y when x = 12
[tex]10x + 12y = 300[/tex]
[tex]10(12) + 12y = 300[/tex]
[tex]120 +12y = 300[/tex]
[tex]12y = 300 - 120[/tex] --- collect like terms
[tex]12y = 180[/tex]
[tex]y = 180/12[/tex] -- solve for y
[tex]y = 15[/tex]

Why is 3+(-5) equal to -2
Answer:
c
Step-by-step explanation:
Here's an example: 3/5 divided by 7/8.
3/5
_____
7/8
Let's do it WRONG, to see why that's bad. Here's our example, multiplied by something that ISN'T equal to one:
3/5 1 3/5 3/5
_____ * _____ = _______ = ______ = 3/5
7/8 8/7 56/56 1
Multiplying 7/8 by 8/7 turns our denominator into 1, which seems helpful. But it leaves us with the same numerator we started with. Can this be right? Is 3/5 divided by 7/8 equal to 3/5 divided by one, so that 7/8 = 1? Oops, that has to be wrong.
For comparison, here's the RIGHT way:
3/5 8/7 24/35 24/35
_____ * _____ = _______ = _______ = 24/35
7/8 8/7 56/56 1
In this case, what we multiplied by, 8/7 divided by 8/7, is equal to one, because anything divided by itself is equal to one. But 1 over 8/7, which we used up above in the first example, is NOT equal to one, which means that if we use 1 over 8/7, we change our question. We may get an answer, but it won't be the right one.

Work out the mean of these numbers:
root 27, root 48, root 75
give your answer in the form a root 3 where a is an integer
Answer:
4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplify the radicals
[tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]
[tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]
[tex]\sqrt{75}[/tex] = [tex]\sqrt{25(3)}[/tex] = [tex]\sqrt{25}[/tex] × [tex]\sqrt{3}[/tex] = 5[tex]\sqrt{3}[/tex]
Now mean is calculated as
mean = [tex]\frac{sum}{count}[/tex] , then
mean = [tex]\frac{3\sqrt{3}+4\sqrt{3}+5\sqrt{3} }{3}[/tex] = [tex]\frac{12\sqrt{3} }{3}[/tex] = 4[tex]\sqrt{3}[/tex]
which of the following shows the correct meter reading consumed? a.2419KW b.2491KW c.2548KW d.2584KW pls answer thank you
Answer:
c.2548KW
Step-by-step explanation:
The correct reading of the meter is;
First meter,---2000
Second meter----500
Third meter ------40
Fourth meter -------8
Total 2000+500+40+8 = 2548 kilo watts.
The answer option A,B, and D are not correct because the answers have incorrect meter reading values.
4 times a number equal 5 less than a number times 8.
Answer:
4n=8n-5
Step-by-step explanation:
Answer:
Let the number be x
As per statement, 7 less than 4 times a number equals 13
4x - 7 = 13
4x = 13 + 7
4x = 20
x = 20 / 4
x = 5
The number is 5
Answer the number is 5
Let us check the correctness of answer by following the statement viz 7 less than 4 times a number equals 13
4 × 5 - 7 = 13
20 - 7 = 13
13 = 13
Means answer is correct

Are the triangles similar? If they are, identify the similarity ratio.
Divide the corresponding sides
3/6 = 0.5
5/4 = 1.25
6/8 = 0.75
We get different results, so the sides are not in the same ratio or proportion.
The triangles are not similar.Sara reduced the time it takes her to run a mile from 8

Select all the zeros of the function f(x)=(x+10)(x−5)(x+1).
– 10
– 5
– 1
0
1
5
10
Answer:
-10, -1, 5
To find the zeros of a function, you have to set each factor to zero in separate equations, and then solve for x.
x+10=0
Subtract 10 from each side
x=-10
x-5=0
Add 5 to both sides
x=5
x+1=0
Subtract 1 from both sides
x=-1

12^2 = 144
16 ^ 2 = 256
256+144 = 400
sqrt(400) = 20
hope this helps!
Answer:
The hypotenuse is 20 cm :)
Step-by-step explanation:
Using a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
c = sqrt(400)
c = 20 cm
