...your sister spent her WHOLE allowance? im not sure if u wrote this problem correctly.
lets just pretend your sister IS spending 7 dollars each week. you're saving while she is spending (smart).
80 + 6w = 145 - 7w
...subtract 80
6w = 65 - 7w
...ad 7w
13w = 65
...divide 13
w = 5
it will take only 5 weeks for you two to have the same amount of money.
Answer:
102cm²
Step-by-step explanation:
Surface Area = BH +Lp
B is the base area
H is the height of the Prism
L is the slant height
p is t perimeter of its base
B =1/2 ×3×4
B= 6cm²
H = 7cm
L = 5cm
P = 3cm+4cm+5cm
P = 12cm
Substitute
TSA = 6(7)+5(12)
TSA = 42+60
TSA = 102cm²
Hence the total surface area of the shape is 102cm²
I don’t know sorry I hope you figure it out
