Bananas cost: $0.25
Apples cost: $0.30
4b+5a=2.50
10b+3a=3.40
You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have
12b+15a=7.50
50b+15a=17
Subtract them and end up with
-38b=-9.5
solve: b=0.25, substitute b in any equation and get a=0.30
Hope this helped
Answer: Area = 26π + 20 cm²
<u>Step-by-step explanation:</u>
There are 2 large semicircles = 1 large circle
There are 2 small semicircles = 1 small circle
There is 1 rectangle.
Find the Area of each shape above and then find their sum.
1) Large Circle: A = πr², d = 10 --> r = 10/2 = 5
A = π(5)²
= 25π
2) Small Circle: A = πr² , d = 2 --> r = 2/2 = 1
A = π(1)²
= π
3) Rectangle: A = length × width, L = 10 w = 2
A = 10 × 2
= 20
Total = Large + Small + Rectangle
= 25π + π + 20
= 26π + 20
Answer:
$87025
Step-by-step explanation:
Net worth is assests minus liabilities
Πr²h(2)-πr²h(1)=πr²(h(2)-h(1))=V2-V1
V2-V1=πr²(h(2)-h(1))
314-188.4=π*2²(h(2)-h(1))
(h(2)-h(1))=(314-188.4)/4π=10
difference is 10 cm
