Answer:
yes
Step-by-step explanation:
6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.
Answer: yes
Also, you can reduce both fractions.
Divide the numerator and denominator of 6/12 by 6 to get 1/2.
Divide the numerator and denominator of 15/30 by 15 to get 1/2.
Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.
The expression that is equal to a x a x a x b x b is a³ x b²
Answer:
A = 89 m^2
Step-by-step explanation:
First, find the area of the rectangle
A = L x W
A = 13 x 8
A = 104 m^2
Next, find the area of the triangle
A = 1/2BH
A = 1/2 (5)(6)
A = 1/2(30)
A = 15 m^2
Now subtract the area of the triangle from the area of the rectangle.
104 - 15 = 89 m^2

Answer:
The Riemann sum equals -10.
Step-by-step explanation:
The right Riemann Sum uses the right endpoints of a sub-interval:
where
To find the Riemann sum for with n = 5 rectangles, using right endpoints you must:
We know that a = -6, b = 4 and n = 5, so
We need to divide the interval −6 ≤ x ≤ 4 into n = 5 sub-intervals of length
Now, we just evaluate the function at the right endpoints:
Finally, just sum up the above values and multiply by 2
The Riemann sum equals -10
We can make and use the equation: <em>A = 160( 1.03 )^y</em>: A = amount, 160 = amount put in, 1 + .03 = 1.03 = interest, and y as the number of years, as the money is compounded every year. (This is the compound interest equation, but I put in the numbers)
A) 160 * 1.03 = $164.80, 160 * 1.03² = $169.744 ≈ $169.74
B) 160 * 1.03⁵ = 185.48385 ≈ $185.48
The expression is the same as saying (((((160 * 1.03)1.03)1.03)1.03)1.03). This is like multiplying 160 * 1.03, which gives the amount for the first year. Then, that amount is multiplied by 1.03, which is the amount for the second year. This isi repeated until 5 years.
C) 160(1.03)³⁰
