The percent of decrease in student absences this year is 33.33%
What is percentage?The percentage is a fraction or a ratio in which the value of the whole denominator is always 100.
Given that the average number of absences in schools was 9 students per day.
This year the average number is 6 students per day.
We need to find the percent of decrease in student absences this year,
So, the percentage of decrease = 9 - 6 / 9 × 100%
= 1/3 × 100
= 33.33%
Hence the percent of decrease in student absences this year is 33.33%

Help I need step by step answer To the ones circled ASAP!!!!
Answer:
4. Multiply both sides by -2 => x - 7 = -36, Add 7 to both sides -> x = -29
5. Add 12 to both sides => 28 = 1/4x, then multiply both sides by 4 => 112
x = 112
7. Multiply both sides by 3 => 5x - 2 = 63, add 2 to both sides => 5x = 65,
Divide both sides by 5 -> x = 13
10. Multiply both sides by 6 => 132 = 3x - 6, Add 6 to both sides => 138 = 3x,
Divide both sides by 3 => x = 46

Answer:
the MAD to this set is 6.75
Step-by-step explanation:
The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.

Answer:
199.51$
Step-by-step explanation:
10 x 12 = 120$
25 x 5 = 125$
5 x 8 = 40¢
1 x 11 = 11¢
30 + 50 = 80$
120$ + 125$ + 40¢ + 11¢ + 80$ = 325.51$
325.51$ - 44$ = 281.51$ - 25$ = 256.51$ - 12$ = 244.51$ - 15$ = 229.51$ - 30$ = 199.51$

What is the volume of the cone to the nearest cubic meter? (Use π = 3.14.) Refer to your STAAR 8th Grade Math Reference Sheet for the appropriate formula.
Height: 5 m
Radius: 4 m
Answer:
V≈83.78
Step-by-step explanation:
The formula to find the volume of a cone is V=πr(squared) h/3
Steps
V= π (4)^2 5/3
V= π (16) 1.66666666667
V = 50.2654824574 * 1.66666666667
v= 83.7758040958
Round
V = 83.78
Answer:
The volume of cone is 83.73m³.
Step-by-step explanation:
Given Parameters:Height of the cone = 5m Radius of the cone = 4mTo find:Volume of the coneSolution:To find the volume of the cone we use Formula:
[tex] \sf V = \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: \frac{1}{3} \times 3.14 \times {4}^{2} \times 5 \\ \\ \implies \frac{1}{3} \times 15.70\times 16 \\ \\ \implies \: \frac{1}{ \cancel3} \times \cancel{251.20} \\ \\ \implies \sf \pink{83.73 {m}^{3} }[/tex]
Hence, the volume of cone is 83.73m³.
