By using the fact that the angles form a linear pair, we will see that the measure of angle C is 144 degrees.
How to determine the measures of angles C and D?
Well, we know that these are a linear pair, which means that the angles are supplementary, thus, their measures add up to 180°.
So we can write:
C + D = 180°
Now, we also know that C is four times larger than D, so we can write:
C = 4*D
Replacing that in the equation above we get:
4*D + D = 180°
5*D = 180°
D = 180°/5 = 36°
Then we know that the value of D is 36°, and C is 4 times that, so:
C = 4*36° = 144°
The measure of angle C is 144 degrees.

11.4 is the slowest time 100 meters can be run to make the team .
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Total time we spent 100 meters track = 12 sec
he ratio must be less that or equal to = 0.95
slowest time 100 meters can be run to make the team = 12 × 0.95

A whale is swimming at a constant rate toward the ocean floor. The equation y = -9x − 5 can be used to represent this situation, where y is the depth of the whale in meters below sea level and x is the number of seconds the whale has been swimming. Which statement best describes the depth of the whale, given this equation?
Answer:
C. From a starting point of 5 meters below sea level, the whale is descending 9 meters per second.
Step-by-step explanation:
Which statement best describes the depth of the whale, given this equation?
A. From a starting point of 9 meters below sea level, the whale is descending 5 meters per second.
B. From a starting point of 9 meters below sea level, the whale is ascending 5 meters per second.
C. From a starting point of 5 meters below sea level, the whale is descending 9 meters per second.
D. From a starting point of 5 meters below sea level, the whale is ascending 9 meters per second.
Solution:
A linear equation is an equation in the form y = mx + b, where m is the rate of change (slope) and b is the initial value of y when x = 0, y is a dependent variable and x is an independent variable.
Given that: y = -9x - 5
Comparing with the equation of a straight line, m = -9 and b = -5
Since m = -9, The negative sign means descending, therefore the whale is descending at 9 meters per second.
b = -5, the negative sign means below sea level, hence the starting point of the whale is 5 meters below sea level,

Which function represents the relationship shown in the table?
Answer:
B
Step-by-step explanation:
The normal absolute value notation " | x | " does not round the value on the inside up or down. If 5.6 was the input, 5.6 would be the output.
I have not seen the notation in B before, but it is the only option available that seems logical enough to represent the pattern in the chart. The hooks on the bottom of the "|"'s appear to represent that it rounds down. If I were to answer this question, that would be my choice.

While practicing her foul kicks for soccer, Louisa made 85% of her shots. If she made 51 shots, how many shots did she kick in total?
Answer:
the exact answer is 58.65
Step-by-step explanation:
since she made 85% of her shots, that means in total from her 51 shots, she made 115% more than 51 (you add 15% to 100%). The 15% is from the difference of 100% and 85%. You then change 115% to fraction form (1.15) and multiply it by the amount of shots made, getting you 58.65. Since you can't make a fraction in terms of a real life scenario like this, you prob need to round or something. Diff teachers want diff things
how many natural numbers?
from 78 to 234
how many whole numbers
from 24 to 721
Answer:
158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721.
Step-by-step explanation:
Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself. That is 158 natural numbers. Whole numbers are numbers without a fraction or decimal, they are integers. So all numbers from 24 to 721 would be included, as well as 24 and 721 itself. That is 699 whole numbers from 24 to 721.

Jon types 54 words per minute.
Step-by-step explanation:
If Jon typed 36 words in 2/3 of a minute, we need to divide 36 by 2.
36 ÷ 2 = 18
Therefore, Jon types 18 words in 1/3 of a minute. In order to find how many words are typed per minute, we must multiply 18 by 3.
18 x 3 = 54
Therefore, Jon types 54 words per minute.

An ant went 2 meters away from its nest searching for food. The next time, the ant went 3 meters away. Each successive time the ant leaves the nest to search for food, the ant travels the sum of the two previous times. How far will the ant travel on his fifth trip?
Answer:
The first time, the ant went 2m away, then we have a₁ = 2m
The second time, the ant went 3m away, then we have a₂ = 3m
The next time, the ant went a distance equal to the sum of the two previous ones, so we can write it in a general case as:
aₙ = aₙ₋₁ + aₙ₋₂
Only if n > 2.
then the third time, we have n = 3.
a₃ = a₂ + a₁ = 2m + 3m = 5m
a₄ = a₃ + a₂ = 3m + 5m = 8m
a₅ = a₄ + a₃ = 5m + 8m = 13m
This means that in the fifth trip, the ant went 13 meters away from its nest.
And if we consider the fact that the ant must go and return, then it will move a total distance of 13 meters two times, or 2*13m = 26 meters.

While Matt was building a new home, he built an area of 180 square feet. He cut two 8 foot by 4-
foot windows on the wall. How much wall was left over after he cut out the windows?
Answer:
16 square feet was left over after he cut out the windows
Step-by-step explanation:
The formula of the area of a rectangle is A = l × w, where
l is the length of the rectanglew is the width of the rectangle∵ The dimensions of each window are 8-foot by 4-foot
∴ l = 8 feet and w = 4 feet
→ By using the rule above find the area of each window
∵ A = 8 × 4
∴ A = 32 feet²
∴ The area of each window = 32 feet²
∵ He cut 2 windows
∴ The area of the 2 windows = 2 × 32
∴ The area of the 2 windows = 64 feet²
∵ The area of the wall is 80 feet²
→ To find the area of the wall left, subtract the area of the windows from
the area of the wall
∵ The area left = 80 - 64
∴ The area left = 16 feet²
∴ 16 square feet was left over after he cut out the windows

Triangle JKL has an area of in2 and a perimeter of in.
Answer:
Area = 24 in²
Perimeter = 24in
Step-by-step explanation:
To find the area given the length of the 3 sides:
a= 8in
b= 6.4in + 3.6in= 10in
c= 6in
Add them together:
8in + 10in + 6in
= 24in²
To find the perimeter you do the same thing:
a= 8in
b= 10in
c= 6in
Add them together
=24in

Select the correct answer. Given the following formula, with A = 27 and t = 3, solve for r.
Making r the subject of the formula, r is solved as: B. r = (27 - P)/3P.
How to Solve the Subject of a Formula?Given the formula, A = P(1 + rt), where:
A = 27 and t = 3
To solve for r, make r the subject of the formula as shown below:
A = P(1 + rt)
Divide both sides by P
A/P = 1 + rt
Subtract 1 from both sides
A/P - 1 = rt
(A - P)/P = rt
Multiply both sides by 1/t
(A - P)/P × 1/t= rt × 1/t
(A - P)/Pt = r
r = (A - P)/Pt
Substitute A = 27 and t = 3 into the formula
r = (27 - P)/P3
r = (27 - P)/3P
Therefore, making r the subject of the formula, r is solved as: B. r = (27 - P)/3P

What value of n makes the equation true?

n=
Answer:
n=-18
Step-by-step explanation:
Steps:
multiply 3 by both sides of the equation
2. cross out the 3 from [tex]3(\frac{2}{3} )[/tex] and you will get 2 and then do -12 x 3 and you will get -36.
3. you now have 2n=-36
4. divide both sides by 2 to isolate n by itself.
[tex]\frac{2n}{2} =\frac{-36}{2}[/tex]
5. divide by crossing out 2 and 2 on the right and then do -36 ÷ 2 which will give you n= -18
Hope this helps :) if you have any questions let me know.
Hi!
To find the value of n in the given equation, multiply both sides by 3.
That way, you'll clear the fractions and solving for n will be easier.
[tex]\implies\boldsymbol{\displaystyle\frac{2}{3} n\times3=-12\times3}[/tex]
Watch what happens:
[tex]\implies\boldsymbol{\displaystyle\frac{2}{\not3} n\times\not3=-36}[/tex]
On the LHS, the 3's cancel out, and we're left with 2n:
[tex]\implies\boldsymbol{2n=-36}[/tex]
Now, divide both sides by 2:
[tex]\implies\boldsymbol{n=-18.}[/tex]
Voila! There's our solution.
Have a nice day!
