Answer:
P = (18a+10b+13) cm
Step-by-step explanation:
Given that,
A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.
We need to find an expression that represents the perimeter of the triangle.
Perimeter = sum of all sides
P = (10a+9) + (8a-3) + (10b+7)
Taking like terms together,
P = (10a+8a)+10b+(9-3+7)
= 18a+10b+13
Hence, the epresssion for the perimeter is (18a+10b+13) cm.
Answer:
61%
Step-by-step explanation:
Area of square:
=a²
=12²
=144
Area of two quarter circles:
=2(¼×π×r²)
=2(¼×π×6²)
=2×28.72
=56.55
Finding the percentage:
=(56. 55÷144)×100
=0.3937×100
=39.27
<u>subtract</u><u> </u><u>100</u><u>%</u><u> </u><u>by</u><u> </u><u>39.27</u><u>%</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>the</u><u> </u><u>percentage</u><u> </u><u>of</u><u> </u><u>how</u><u> </u><u>much</u><u> </u><u>is</u><u> </u><u>shaded</u>
<u>=</u><u>100-39.27</u>
=60.73
=61 (rounded off to the nearest whole percent)
You spent 40% of your budget.
10/25=2/5=40/100
i dont know, my personal thoughts is that I will not do it:)
