Step-by-step explanation
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$

Today is Maria's birthday. She is 7 years old. How old is Maria in months?
Answers
Answer:
84 months
Step-by-step explanation:
Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.
12 * 7 = 84
Maria is 84 months old
Answer:
Maria is 84 months old.
Multiply the years(y) by every 12 months that pass(m).
[tex]y * m = 84[/tex]
note that y is 7, and m is 12, because we count every 12 months that pass for 7 years.
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
Answers
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.

Answer:
(b) y = 4x +15; y = 10x -2
Step-by-step explanation:
It is often sufficient to check for reasonableness in the offered answers. That is the case here.
__
The offered answer choices differ in the combinations of slope. The offered slopes (x-coefficients) are 4 or 1/4, 10 or 1/10, so it is sufficient to determine if the slope is greater than 1 in each case.
The slope is the ratio of the change in y to the change in x. It will be greater than 1 if y changes by a larger number than x does.
1st Tablex-values in this table change by 4-2 = 2. y-values change by 31 -23 = 8, which is more than 2. The slope is greater than 1 for the first equation. (It is 8/2 = 4.)
2nd TableThe first two x-values in this table differ by 0-(-1) = 1. The first two y-values differ by -2-(-12) = 10, which is more than 1. The slope is also greater than 1 for the second equation. (It is 10/1 = 10.)
Answer choicesThe x-coefficients in the answer choices are ...
a) 1/14, 1/10 . . . incorrect
b) 4, 10 . . . . correct
c) 1/4, 10 . . . . partly correct
d) 4, 1/10 . . . . partly correct
