There are 64 boys in the class because 24/3=8 and you have to do the same thing so 8 times 8= 64
Answer:
2 1/3 planes
Step-by-step explanation:
3.5 lego planes / 60 minutes
So fraction =
3.5/60
In 40 minutes he will build x planes
So the fraction equation is:
3.5/60 = x/40
Solve:
Cross multiply =
140 = 60x
x = 2 1/3
2 1/3 planes

$3.99/24oz= $0.16/oz (smaller size)
$6.99/64oz= $0.10/oz (larger size)
The larger size has the lower unit costs.
Answer:
Area of this parallelogram: 35.
Step-by-step explanation:
What's the equation for the area A of a parallelogram?
A = b · h,
where
- b is the length of the base, and
- h is the length of the height <em>on that base</em>.
Plot the four vertices on a cartesian plane. Two opposite sides of this parallelogram are parallel to the x-axis. As a result, the length of the base is the same as the difference in x-coordinates between two vertices on that side. As seen on the diagram, the length of this base is b = 2 - (-5) = 7.
The height on either of those two sides will be normal to the x-axis and parallel to the y-axis. The length of those heights will be the same as the difference in y-coordinates between two vertices, one on each line. As seen on the diagram, the length of the height on base <em>b</em> is h = 4 - (-1) = 5.
Area of this parallelogram:
A = b · h = 5 × 7 = 35.
Answer:
4.8 (you can check but that's what I got)
Step-by-step explanation:
First find the missing angle by subtracting the sum of the two given from 180°
43°
Then use the Law of Sines to find the missing side
x/sinC = a/sinA
x/sin(90°)/3.5/sin(47°)
x=sin(90°)×(3.5/sin(47°))
x=4.7856...
x ≈ 4.8
