If one is 5"x3", and the other having the same orientation is 3"x?, then
by similar figures,
5/3=3/x
cross multiply,
5x=3*3
x=9/5=1.8"
With the original figure, it is possible to validate the above answer.
7: $200<3x-y(28) where x represents each kids money out of it and y represents the parents pay.
8: 7.00>(is greater then or equal to) 0.75X + 1.29Y where X is the amount of bagels and Y is the amount of cream cheese containers.
9: $25 + $75>4X where X is the shirts
10: 720-120>(greater then or equal to) 32X where X is the number of people in each row
11: 2400= 2100+ X(1/20) where X is the value of all things sold.
12: 2000<(X7)-668 where X is the amount of cans in one day.
13: 100> 7X - 10Y where X equals the amount of months and Y equals the amount of CD's
14: $80 - $22> (greater than or equal to) 17X where x equals the amount of shirts.
first off sorry it took so long to answer, these long word questions are time consuming and i havent done them in a while so i had to refresh my memory, secondly the equations all end where i say the word "where", thirdly i am absolutely sure of all these answers except for the first one, the first one i am pretty sure i still got it but not 100%.
hope this helps.
Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.
Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:
r= 10 ft
Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
Answer:
10) 2/3 > 0.6
11) 7% < 7/10
12) 6.5 = 650%
13) 38%, 0.4, 5/8
14) 1/2, 0.55, 57%
Step-by-step explanation:
I changed everything to decimal form to make it easy
10) 2/3 = 0.66
11) 7/10 = 0.7 7% = 0.07
12) 650% = 6.5
13) 5/8 = 0.625 38% = 0.38
14) 1/2 = 0.5 57% = 0.57
Step-by-step explanation:
the formula can be;
X+9x=10
10x=10X=10/10=1
X=1+9(1)=1+9=10 Answer
