Answer:
8:125
Step-by-step explanation:
The ratio of the lengths would be the scale factor
The ratio of the volumes is the scale factor cubed
2^3 : 5^3
8:125
Answer:
by u meant 32n^4, then the answer is 2n^4
Step-by-step explanation:
first find the gcf of the coefficient
32 and 34
their gcf is 2, because they're both even but have no other common factor, so it is 2
then for the variables
n^4 and n^5
their gcf is n^4. you can tell by dividing each term by n^4
n^4 / n^ 4 = 1
n^5 / n^4 = n
so then 2 * n^4 is 2n^4
Consider one pyramid
Side length of base = 1.5cm and its height is 1 cm
Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm
Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375
= 7.5 cm^2 Answer
Answer:
x = 7.3
Step-by-step explanation:
When solving for missing sides using angles, use trig functions.
We have the angle 63° to use.
We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.
Cos T = (adjacent side)/(hypotenuse)
Here we know 'T' and the hypotenuse, so plug them in and solve
Cos 63° = x/16
(16)Cos 63° = x (multiply both sides by 16 to isolate 'x')
7.263847996 = x (use your calculator to solve the left side)
7.3 = x (rounded to the nearest 10th)
