Answer:
3.245
Step-by-step explanation:
2.22+1.51+1.86+2.06+3.48+4.57+3.27+5.40+5.45+4.34+2.64+2.14 then divide by twelve because that is the number of months :))))
Answer:
3.8×10^7= 38000000
1.9×10^6= 1900000
38000000÷1900000= 20
the population of California is 20 greater than the population of Nebraska
Answer:
Step-by-step explanation:
The average length of the weird trapezoidal shape on the left is
(2 m + 10 m)/2, or 6 m. The width is 4 m, so the area is 24 m^2.
The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.
Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.
Answer:
Option C = 335.5 in²
Step-by-step explanation:
Area of triangle = (1/2)×b×h
= (1/2)×a×a
= (1/2)×11×11
=60.5 in²
Area of rectangle = l×b
= b×a
= 25×11
= 275 in²
Area of pencil = Area of triangle + Area of rectangle
=60.5 + 275
335.5 in²
Answer:
6.4 m
Step-by-step explanation:
We have 2 expressions here. The first one is the fact that r = y. That's one of 2 equations. The second one involves whats' left after cutting off certain lengths of each color string. We cut 2.5 m from red, we cut 3.8 m from yellow. We know that what's left of red is 1.5 times the length of what's left of yellow. What's left of red is r - 2.5; what's left of yellow is y - 3.8. We know that r = 1.5y, so filling that in with our corresponding expressions gives us
r - 2.5 = 1.5(y - 3.8)
Distribute to get
r - 25 = 1.5y - 3.2
Now from the first expression, r = y, so fill in y for r to get an equation in one variable:
y - 2.5 = 1.5y - 3.2
Combine like terms:
-.5y = -3.2 and divide to get
y = 6.4
Check it to make sure it works. What's left of red should be 1.5 times the length of what's left of yellow and y = 6.4:
What's left of red: 6.4 - 2.5 = 3.9
What's left of yellow: 6.4 - 3.8 = 2.6
1.5 x 2.6 = 3.9, just like it should!
