Answer:
2.5 is the scale factor
Step-by-step explanation:
Skills needed: Identifying the Scale Factor, Division
1) First, we need to understand what the scale factor is.
A scale factor is the value being multiplied by one side of a figure to form another figure that is bigger or smaller. For example:
Let's say you are given a triangle with side lengths 3 cm, 4 cm, and 5 cm and you are supposed to find the side lengths of a new triangle when the scale factor being used is 2. Here, you would multiply all the sides by the value 2. So, the 3 sides are:3 x 2, 4 x 2, and 5 x 2 ---> 6 cm, 8 cm, 10 cm.
2) So to find the scale factor in a problem, you would do the side of one triangle divided the corresponding side of the other triangle.
So to find the scale factor in the above problem (if we were only given side lengths 3 cm, 4 cm, and 5cm & also 6 cm, 8 cm, and 10 cm), you would do:
[tex]\frac{6}{3}[/tex] or [tex]\frac{8}{4}[/tex] or [tex]\frac{10}{5}[/tex], all of which equal 2.
3) So in this problem, you would simply do [tex]\frac{10}{4}[/tex], since 10 and 4 are corresponding sides of dilated triangles.
This is [tex]\frac{5}{2}[/tex] when simplified, or 2.5 as a decimal, since scale factors are usually expressed as decimals.
Hope this helps and have a nice day!! :) :] :D

factorise -21t²+12t+33
Answer:
3(−7t+11)+(t+1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Explanation:
~ Combine like terms
~ Like terms have the same variables
−21t^2 + 12t + 33
= 3(−7t + 11) + (t+1)
Which gives you your answer.

Three line segments have measures of 17 units, 11 units and 12 units. Will the 1 point
segments make a triangle? *
O No
O Yes
Answer:
No
Step-by-step explanation:
The smaller amounts (11 and 12) have to add to be equal to or greater than the larger amount (17).
Hope it helps!
Answer:
No
Step-by-step explanation:
Because the formula for finding the hypotenuse of a triangle is a^2+b^2=c2.
so it will be 11^2 + 12^2 = c^2

In triangle nop the measure p=90degrees n=27 degrees and pn= 50 feet find the length of no to the nearest tenth
Answer:
56.1feet
Step-by-step explanation:
Triangle NOP is a right angled triangle;
NP is the adjacent side = 50feet
NO is the hypotenuse
m<N = 27degrees
Using the SOH CAH TOA identity;
Cos theta = Adjacent/Hypotenuse
Cos m<N = NP/NO
Cos 27 = 50/NO
NO = 50/cos27
NO = 50/0.8910
NO = 56.1 feet
Hence the length of NO to the nearest tenth is 56.1feet

Find the first 5 terms in the following sequence:
Answer:
23,30,37,44,51
Step-by-step explanation:
an = an-1 +7
We know a1 =23
a2 = a1 +7 = 23 +7 =30
a3 = a2 +7 = 30+7 = 37
a4 = a3+7 = 37+7 = 44
a5 = a4+7 = 44+7 = 51
The first 5 terms
23,30,37,44,51

When It asked to find sin, cos, tangent of a angleIf you finding the sin of a angle you must find the side that is Opposite then put it over the hypotenuse I'll do 3,6,7,8 for you.
For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.
For 6, 32 is opposite of A and 40 is the hypotenuse so
32/40 or 4/5 is our answer.
For 7, 24 is opposite of Z and 40 is the hypotenuse so
24/40 or 3/5 is the answer.
For 8, 14 is opposite of Angle C and 50 is our hypotenuse so
14/50=7/25 is our answer
COS
To find cos it is adjacent/hypotenuse
For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.
For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17
For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.
TAN
TO FIND TAN, it is Opposite/Adjacent
4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.
10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4

plzzz help! what expersion is equivalent to it?
Answer:
[tex]64x^{12}[/tex]
Step-by-step explanation:
We have to use the law of indices for finding the equivalent expression.
[tex](8x^{5})^{2} = 64x^{10}[/tex] We square 8, which is 64 and multiply the two powers.
[tex](x^{4})^{\frac{1}{2}} = x^{2}[/tex] We multiply the 2 powers giving us, [tex]\frac{4}{2}[/tex], which simplifies to 2.
[tex]64x^{10}[/tex] × [tex]x^{2}[/tex] = [tex]64x^{12}[/tex] This is the answer as we multiply the two indices together.
I hope this helps!! ^-^
Answer:
64x¹²
Step-by-step explanation:
(8x^5)^2 × (x^4)^1/2
64x^10 × (x^4)^1\2
