Answer:
3125 x 5th root (x)
Step-by-step explanation:
(3125 ) * x^(6/5)
When we have a some thing to a power greater than 1, we can separate it
We can rewrite 6/5 as 5/5 + 1/5
3125 x^(5/5+1/5)
We know a^ b *a^c = a^(b+c)
3125* x^5/5 * x^ 1/5
x^5/5 is x^1 or just x
3125* x * x^ 1/5
3125 x 5th root (x)
Answer:
-277.02
Step-by-step explanation:
Given series:
- -3.42, 10.26, -30.78, 92.34,...
We can see the series is a GP with common ratio of -3, as:
- 10.26/-3.42= -30.78/10.26= 92.34/-30.78= -3
So the next term will be:
The number you are looking for is 7.
(a)
The ratios of corresponding sides are equal
= 2 ← scale factor
hence w = 2 × 2.3 = 4.6 cm
(b)
The perimeters are linear and will also be proportional with a scale factor of 2
the areas are proportional with scale factor 2² = 4
That is the area of rectangle B is 4 times the area of rectangle A
In general
If 2 figures are similar then linear ratio of sides = k
Then the ratio of their areas is k²
and the ratio of their volumes is k³
Estimate -6.1(0.22)
Answer:
Use rounding to get -6(0.2), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
Round the factors to the nearest whole number, and then multiply.
Step-by-step explanation:
Actual answer:
-6.1(0.22) = -1.342
Estimate answer:
-6 (.2) = 1.2
