Answer:
there are four significant figures
Step-by-step explanation:
zeros to the right of a non zero digit are ambiguous
Answer:
No
Step-by-step explanation:
I don't think those are equivalent because 7/8 is positive while -7/-8 is negative.
(If you are)- Solving The Equation
1. Multiply both sides by eight over three
8/3•1/2 = 8/3•3/8 which gives you 4/3.
2. Swap the sides of the equation
4/3=y turns into y= 4/3 and that’s your answer. (y=4/3).
(Or if you’re working on)- Rewrite In Standard Form
Swap 1/2 and 3/8y , so it should be 3/8y=1/2.
Then multiply both sides by 8/3, and that should give you y=4/3.
Then multiply both sides of the equation by 3, and that should give you 3y = 4. And 3y=4 would be your answer.

Answer:
28+104 = 132cm^2
Step-by-step explanation:
We can find the area of this figure by breaking it into two separate pieces. The top is a rectangle and the bottom is a trapezoid.
A rectangle = l*w = 7*4 = 28 cm^2
A trapezoid = 1/2 (b1+b2) *h = 1/2 (19+7) *8 = 1/2 (26)*8 =104 cm^2
Add these areas together
28+104 = 132cm^2
