S = 2lw + 2lh + 2wh
S = 2(12)(5) + 2(12)(7) + 2(5)(7)
S = 2(60) + 2(84) + 2(35)
S = 120 + 168 + 70
S = 288 + 70
S = 358 in²
I’m pretty sure it’s the 2nd one
The rectangle is 28×34 and the two triangles are (1/2) 11 (28) and (1/2) (9)(34)
A = 28(34) + (1/2) 11 (28) + (1/2) (9)(34)
A = 1259
Answer: 1259 sq units
Answer:
Sam made an error subtracting 258 from 270.
Step-by-step explanation:
0.043 / - 0.2709 /- 258 = 129. 129 - 129 = a remainder of 0 and quotient of negative 63.
Should actually answer and be 0.00061523317
So if sam rewrote this as;
0.043 / - 270.9 /- 258 = 6.15233173
There is no 63 or 6.3 or 630 answer possible and 5 decimals to the right would be absurd.
Answer:
D. A travels 90 miles more
Step-by-step explanation:
The graph tells you Car A travels 140 miles on 5 gallons of gas. (There is a point marked there on the graph.)
The table tells you Car B travels 99 miles on 4.5 gallons of gas. When that is multiplied by 5/4.5 = 10/9 to get the equivalent for 5 gallons, we see that Car B could travel 10/9 × 99 = 110 miles on 5 gallons of gas.
__
Already <em>on 5 gallons of gas</em>, Car A has traveled <em>30 miles farther</em>. The only sensible answer choice is ...
D. Car A travelled 90 miles more than Car B [when 15 gallons are used].
