Matt is painting a mural on a 1-square meter section of a wall. He has completed a rectangular part of the mural that is four sixths of a meter wide and two fifths of a meter tall. What part of the mural has been completed?
Answer:
26.66%
Step-by-step explanation:
In order to calculate how much of the mural has been completed, we need to find the area of the rectangle. Since both the length and the width have been provided we simply multiply these values together and to find the amount of the mural that has been completed...
[tex]\frac{4}{6} * \frac{2}{5} = \frac{8}{30}[/tex] or 0.2666[tex]m^{2}[/tex]
We can see that 0.2666[tex]m^{2}[/tex] have been completed. Now we can divide this by the total size of the mural to calculate the percent that is completed.
0.26666[tex]m^{2}[/tex] / 1[tex]m^{2}[/tex] = 0.2666 ... multiply by 100 to get percent value
0.2666 * 100 = 26.66%
Finally, we can see that a total of 26.66% of the mural has been completed.
Answer: 8/30 (or eight thirteenths) in fraction form, and 26/66% in percentage form :)
Solve for r.
-13 = r/9 +8
Answer:
r = - 189
first:
-13 -8 = -21
add the two negative number together and get -21
second:
r/9 >> 9 * -21
multiply 9 and -21 together and get -189
r = -189

Answer:
64
Step-by-step explanation:
Let the tens digit be x and units digit be y. We can write the number we are finding as 10x + y. We also know that x + y = 10 and 10x + y - (reversed number) = 10x + y - (10y + x) = 9x - 9y = 18.
Dividing by 9 on both sides, we get:
x - y = 2
Using the equations x + y = 10 and x - y = 2, we find that x = 6 and y = 4. So the number is 64.
I hope this helps! :)

Select all the expressions that have a value of 40 when x = 10.8.
4,320 ÷ x
Answer: Option C.
Step-by-step explanation:
x = 10.8
A. = 4,320 ÷ x
= 4,320/10.8
= 400
Option A is incorrect.
B. = 288/x + 16
= 288/10.8 + 16
= 42.7
Option B is incorrect
C. = (x² ÷ 18) + 33.52
= (10.8² ÷ 18) + 33.52
= 40
Option C is correct
D. = (1,752 ÷ x) – 162/29
= (1,752 ÷ 10.8) – 162/29
= 156.6
Option D is incorrect
E. = x/12 + 36
= 10.8/12 + 36
= 36.9
Option E is incorrect
Answer:
x = 10.8
432 ÷ x = 40
(216 ÷ x) + 20 = 40
(108 ÷ x) + 30 = 40
(54 ÷ x) + 35 = 40
Step-by-step explanation:
A small town has two local high schools. High School A currently has 600 students
and is projected to grow by 65 students each year. High School B currently has 950
students and is projected to grow by 30 students each year. Let A represent the
number of students in High School A in t years, and let B represent the number of
students in High School B after t years. Write an equation for each situation, in terms
of t, and determine after how many years, t, the number of students in both high
schools would be the same.
Answer:
The senior class will have 100 members in the 13th year.
Step-by-step explanation:
Use the compound interest equation with a negative interest rate:
A = P(1 + r/n)^(n)(t)
Let n be 1 since we're looking for a specific year.
100 = 250(1 - 0.07)^t
100/250 = (0.93)^t
0.4 = (0.93)^t
t = 13 years

What is the solution for the equation? 3x + 15 -7x = 27
A. x = -3
B. x = 1.2
C. x = 3
D. x= -10.5
Answer:
A. x = -3
Step-by-step explanation:
add the "x"s together
-4x + 15 = 27
subtract 15 from both sides
-4x = 12
divide both sides by -4
x = -3
A. x = -3 is the answer :)
