Answer:
A. $402,500
Step-by-step explanation:
This can be found two ways:
Option 1:
Multiply 69,100 by 35 and you get 2,418,500.
Next, multiply 57,600 by 35 and get 2,016,000.
Subtract to find difference: 2,418,500 - 2,016,000 = 402,500.
Option 2:
Subtract to find the difference: 69,100 - 57,600 = 11,500.
Multiply 11,500 by 35 and get 402,500

The required equivalent expression to 1/8 is given as 0.125 and 1/4×1/2.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
The given expression is 1/8,
1/8 is a fraction value where in the numerator we have 1 and in the denominator, we have 8.
The expression equivalent can be given in various ways such as,
1/8 = 0.125
or
1/8 = 1 / 4 × 1 / 2
Thus, the required equivalent expression to 1/8 is given as 0.125 and 1/4×1/2.

A runner can complete a 26-mile race in 2.5 hours. What is the runner’s average speed in miles per hour?
Answer:
A noncompetitive, relatively in-shape runner usually completes one mile in about 9 to 10 minutes, on average. If you're new to running, you might run one mile in closer to 12 to 15 minutes as you build up endurance. Elite marathon runners average a mile in around 4 to 5 minutes.

Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.
Assume that Lexus skateboards at a constant rate.
Part A
Write an equation to represent the number of miles, m, that Lexus can skateboard in t minutes.
Answer:
[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]
Step-by-step explanation:
Proportional Model
The number of miles m that Lexus can skateboard in t minutes can be modeled by:
m = kt
It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.
Substituting:
4 = k.20
Dividing by 20
[tex]k=\frac{4}{20}[/tex]
Simplifying:
[tex]k=\frac{1}{5}[/tex]
This produces the model
[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]
I used the equation y=4x+20.

10. In the illustration, triangle D'E'F is formed by
adding 6 units to the y-coordinate of each
vertex of triangle DEF. The best term for
describing triangle D'E'F' is
D שן
A a rotation of ADEF.
B a reflection of ADEF.
C similar to ADEF
D congruent to ADEF.
Please helpppppppp
Answer:
Option (D)
Step-by-step explanation:
Vertices of triangle D'E'F" are formed by shifting ΔDEF 6 units up vertically, transformation will be defined as translation.
Translation, rotation and reflection are the rigid transformations.
And in rigid transformations image and preimage are congruent to each other.
Therefore, ΔD'E'F' is congruent to ΔDEF.
Option (D) will be the answer.
4(y – 10) =- 12 what does y equal help pls
Answer:
y=7
Step-by-step explanation:
4(y-10) = -12
4y - 40 = -12
+40 +40
4y = 28
y = 7
(multiply 4 times y and by -10)
(add 40 to both sides)
(divide both sides by 4)
Answer:
y = 7
Step-by-step explanation:
Hope I helped.
Divide both sides by 4, then solve.
An equation can be defined as a mathematical statement consisting of an equal symbol between three algebraic expressions that have the same value.

If two fractions are between 0 and 1, can their product be more than 1? please explain. Thank You.
Answer:
B) always less than either of the original fractions
Step-by-step explanation:
We can easily Answer this by taking some values.
The question states that the two fractions, each have values between 0 and 1.
Let us say one of the fraction is 1/2 and the other fraction is 1/3 .
The product of the two fractions is 1/2 x 1/3 = 1/6 .
is lesser than both 1/2 and 1/3 .
So, the correct answer is that the product is always less than either of the original fractions.
The two fractions are between 0 and 1 their product will always less than either of the original fractions.
What is fraction?A fraction is number expressed "as quotient, in which the numerator is divided by denominator".
According to the question,
If two fractions are between 0 and 1. In order to check their product be more than 1.
Let us assume one fraction is 1/2 and the other fraction is 1/3. The product of the two fractions:
1/2 x 1/3 = 1/6.
Since the value of fraction 1/2 is 0.5, the value of fraction 1/3 is 0.3333 and the value of fraction 1/6 is 0.166667.
It clearly shows 0.5 > 0.16667 and 0.3333 > 0.16667.
Hence, the two fractions are between 0 and 1 their product will always less than either of the original fractions.
