Answer:
a) 300
b) 900
Step-by-step explanation:
The length of the rectangle is 5 and the width is 3...
But since the rectangles are connected together, we could just work the problem like this:
5 x 2 = 10
_____________
3 x 5 = 15
15 x 2 = 30
The surface area of the shape is 10 x 30 = 300
______________________________________________
If the dimensions of the box were tripple, we would need to multiply the surface area by 3:
300 x 3 = 900
For the second question, the answer would be 900
Hope this helped you :-)
Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.
Answer:
C is correct, D might be correct if you forgot 000 at the end of the question.
Step-by-step explanation:
005 = 5x1 so A is incorrect
945 = 9x100 + 4x10 + 5x1 so B is incorrect
15.859 = 1x10 + 5x1 + 8/10 + 5/100 + 9/1000 + so C is correct
973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect
C D and F because it’s a set rate. 50miles PER hour $10 EACH pizza 5 points for EVERY CORRECT test question. It shows a direct correlation.
Answer:
Instead of moving right 4 times and up 7 times, John moved left 4 times and down 7 times.
Step-by-step explanation:
(x + 4, y + 7) = Right 4, Up 7
NOT
(x - 4, y - 7) = Left 4, Down 7
