Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.
A/78 = 25/100 . . . . the equation
a = 78*25/100 = 19.5
19.5 is 25% of 78
The answer to this question is 50 because you have to multiply 100x50 and you get 5000
Answer:
S = R θ where θ is in radians
If θ = 2 pi then S = 2 pi R the circumference of the circle
θ = S / R = 9.7 / 9 = 1.08 rad
Since 1 rad = 360 / (2 pi) = 57.3 deg
the angle included = 1.08 rad * 57.3 deg/rad = 61.9 deg
<span>6840 customers ... 45 days<span>
x customers = ? ... 1 day
If you
would like to know how many customers were in Jasigreen's class in 1 day,
you can calculate this using the following steps:
6840 * 1 = 45 * x
6840 = 45
* x /45
x = 6840 / 45
x = 152 customers
<span>The
correct result would be </span>152 customers<span>.</span></span></span>
