Answer:
3 + x for both. They did the same amount.
Step-by-step explanation:
Will volunteered 3 hours in march. In April, he volunteered the same amount plus the same amount at Lydia did in March. Since we don't know Lydia's then this is x. So in April, Will volunteered 3 + x.
Hector volunteered 5 hours in March. But in April, he volunteered 2 less than March which 5-2 = 3. Plus he did the same amount as Lydia in March. So his expression is 3+x.
Will and Hector did the same amount of hours.
Answer:
PEMDAS.
parenthesis first, then exponents, next would be mutiplication/division, then lastple add/subtract.
Step-by-step explanation:
first would be 15-7, then the 3^2, etc
9. It is a very good idea to divide by the smallest numbers.
First divide by 2 as many times as you can, then by 3, and so on:
110=2*55 (2 is an obvious factor, since the number ends with 0)
2*55=2*5*11 (5 is an obvious factor since the number ends with 5)
10.a
to find a number with factors 2, 3, 5, just multiply these numbers with any other number you want.
number 1: 2*3*5*4=120
number 2: 2*3*5*9=270
The greatest common factor of these 2 numbers is 2*3*5
any combination of these numbers is a common factor to number 1 and number 2,
so these numbers have in common the factors:
2*3=6, 3*5=15, 2*5=10, 2*3*5=30
that is {6, 10, 15, 30}
b.
a number with 8 as a factor, has also 2 and 4 as factors.
so a number with factors 2, 4 and 8 can be found by simply multiplying 8 by any number.
number 1: 8*5=40
number 2: 8*11=88
number 3: 8*500=4,000
these numbers have in common that they all are multiples of 8 (their greatest common divisor is 8)
Hey there!
Given that this flower bed is circular, it can be assumed that it's a cylinder. In this problem, we need to use the equation for the volume of a cylinder:
V = π r² h
Since we just need to find the area that the mulch will take up, we'll use that given measurement of 4 inches in place of the actual height of the flower garden. Since we need the radius, all we have to do is divide the 12 inch diameter measurement in half to get a radius of 6 inches. Usually for these problems, they'll tell you to use 3.14 for pi instead of the full pi number, so we'll just use that to make things easier.
V = π (6)² (4)
V = π (36)(4)
V = π (144)
V = 452.16
The volume of the mulch needed will be 452.16 in³.
Hope this helped you out! :-)
