Answer:
Find the reciprocal of the divisor
Reciprocal of
15/7 : 7/15
Now, multiply it with the dividend
So, 10/ 21 ÷ 15/7 = 10/21 × 7/15
= 10 × 7/ 21 × 15 = 70/ 315
After reducing the fraction, the answer is
2/9
Answer:
<h3>A. 1.15 x 10^2
</h3>
Step-by-step explanation:
Given the following;
Diameter of the sun ds = 1,391,000 kilometers
Diameter of the Venus dv = 12,100kilometers
Taking the ratio of both diameters;
Ratio = Diameter of sun/Diameter of Venus
Ratio = 1,391,000/12,100
Ratio = 13910/121
Ratio = 114.958
Hence ds/dv = 114.958
ds/dv = 1.149 *10^2
ds/dv = 1.15*10^2
ds = 1.15*10^2 dv
Hence the diameter of the sun is 1.15*10^2 larger than that of the venus.
Answer:
- 2(x - 6)(x - 4)
Step-by-step explanation:
Given
- 2x² + 20x - 48 ← factor out - 2 from each term
= - 2 (x² - 10x + 24) ← factor the quadratic
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 6 and - 4, since
- 6 × - 4 = + 24 and - 6 - 4 = - 10, thus
x² - 10x + 24 = (x - 6)x - 4) and
- 2x² + 20x - 48 = - 2 (x - 6)(x - 4) ← in factored form
Answer:
y = (1/4)x
Step-by-step explanation:
"Direct variation" here signifies y = kx, where k is the constant of proportionality.
Then y = kx. Here we are to find k using the info that x = 12 and y = 3:
3 = k(12), or
k = 3/12, or k = 1/4
Then y = (1/4)x
Answer:
k>1
Step-by-step explanation:
k-4>-3
k>-3+4
k>1
