Answer:
Two consecutive even integers are 32 and 34.
Step-by-step explanation:
Let the two consecutive even integers are x and x+2.
ATQ,
Twice the smaller is 26 less than. 3 times the smaller
2x = 3(x-2) -26
2x = 3x-6-26
2x = 3x -32
32 = 3x-2x
x = 32
Hence, the smaller number be 32 and larger number be x+2 = 32+2 = 34.
Basically, powering something is multiplying something by itself.
so, 2 to the power of 10 is 1024
why? because
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 1024
(see? I multiplied 2 10 times!)
Answer:
2670 square feet. Option e.
Step-by-step explanation:
Dan and Betty can paint 2,400 square feet in 4 hours.
They can paint in one hour
= 600 square feet.
Since given that Betty paints twice as fast as Dan. Let us take an equation:
Let Betty = B, Dan = D and Sue = S
B = 2D
4(B+D) = 2400
4B + 4D = 2400
12D = 2400
D = 200 sq. ft.
B = 2D = 400 sq. ft.
Therefore, Dan can paint 200 square feet in 1 hour and Betty paints twice 400 square feet in 1 hour.
Now given three of them can paint 3,600 square feet in 3 hours.
3( B+D+S) = 3600
3B + 3D + 3S = 3600
3(400) + 3(200) + 3(S) = 3600
1200 + 600 + 3S = 3600
S = 600 Sq. ft.
Sue can paint 600 square feet in one hour.
So sue can paint in 4 hours and 27 minutes.
× 600
= 2670 square feet. Option e.
