Answer:
294.14cm^2
Explanation:
First find the area of the whole piece of paper:
32*14=448
Then find the area of the two semicircles, semicircle + semicircle = 1 circle:
Area of a circle= (radius squared)(pi):
(7^2)(3.14) = 153.86
Subtract the area of the two semicircles from the whole paper area:
448-153.86 = 294.14
I hope this isn’t too confusing :)
Answer:
58
Step-by-step explanation:
1. let x be the unknown number
2. make an expression
x + 26/12 = 7/1
3. cross multiply
x +26 × 1 = x + 26
12 × 7 = 84
x + 26 = 84
4. move variables on one side and numbers on other side of the equal sign
x + 26 = 84
- 26 -26
x = 58
Answer:
Step-by-step explanation:
10m-2/5=9 and 3/5
10m-2/5=9.6 (where 9 and 3/5 is equal to 9.6)
50m-2=48 (i multiplied 10m by 5 and 9.6 by 5)
50m=50 ( i added 2 to both sides)
m=1 ( i divided by 50 to both sides to find m)
Answer:
d)15 apples
Step-by-step explanation:
We know that she gives 2 red apples and 1 green apple to 5 friends and has no more left over. you add 2+1=3 Then you multiply 3x5=15.
Hope this helps! Have a great day ahead. Tell me if I'm wrong :) Stay Safe <3
Answer:
(a) 
(b) We cross multiply the probability by the total voters
(c) 9347
Step-by-step explanation:
(a)
Probability of getting a republican voter is
These are found by dividing the first numerator and denominator by 2, then by 3
To make it complete, the situation is therefore defined as where y is unknown value
(b)
Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.
(c)
Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields
