The correct answer would be (-24). When multiplying with negative integers, negative times negative is positive, however, the final answer, in this case, is negative because you are then multiplying a positive and a negative:
(-2)(-3)=6
6(-4)=(-24)
I'm guessing Jamar's mistake was he multiplied all of them thinking his answer would be a positive integer: 24.
Answer:
452.45mmm^2
Step-by-step explanation:
Step one:
Given data
outer radius R= 20mm
inner radius r= 16mm
let us find the area of the outer circle
Area= πR^2
Area= 3.142*20^2
Area= 3.142*400
Area= 1256.8 mm^2
let us find the area of the inner circle
Area= πr^2
Area= 3.142*16^2
Area= 3.142*256
Area= 804.35 mm^2
Hence the area of the section is
Area of outer- Area of inner
=1256.8-804.35
=452.45mmm^2
1. Zoe stacked the most brownies. She stacked 27 brownies out of the 50 brownies.
2. 15
3. 43 + 3n ≥ 70, so n ≥ 9
4. D. 58x + 13 + 58y
5. The answer would be ≤4
6. 9.94 + 10.01p ≤ 70, so p ≤ 6
7. C 40 89
8. D. x+(x+5)=77

Answer:
a)D= 0.625 Decimal that describes the portion of the workday he has finished
b)P= D*100= 0.625*100=62.5%
P: percentaje
D: Decimal
Step-by-step explanation:
Nomenclature
F: fraction of daily workday
D: decimal of daily workday
P: percentage of daily workday
Formulas
F= a/b
D= a÷b
P= D*100
Problem development
We have:
F = 5/8, then:
D= 5÷8= 0.625
To obtain the percentage of the workday that Matew has completed, we multiply the decimal x 100
P= 0.625*100=62.5%
Answer:
B
Step-by-step explanation:
Slope:
This eliminates answer options C and D
If you plug either set of coordinates into equation B then you will know that it works because both sides will end up equal to each other
