Answer:
13
Step-by-step explanation:
We now that the two angles are equal due to them being vertical angles. This way, we can safely set them equal to each other.
4x - 14 = 58
To find what x equals, we first need to get x by itself. That means now we have to add 14 on both sides, leaving us with:
4x = 72
Now we divide 4 on both sides:
x = 13

The mass of 25 packets of biscuits is 0.7kg. There are 4 biscuits in 1 packet. What mass of 1 biscuit?
Answers
Answer:
0.007 kg
Step-by-step explanation:
There are 25 packets
Each packet contains 4 biscuits.
The total number of biscuits = 4 * 25
The total number of biscuits = 100
100 biscuits = 0.7 kg
1 biscuit is 0.7 kg / 100
1 biscuit is 0.007 kg
If you are not sure of this, put it in a calculator.
Just out of curiosity note that 1 kg = 1000 grams
0.007 kg = 0.007 * 1000 = 7 grams each.
use 0.007 as your answer.

Option 4
Step-by-step explanation:

Since, cos2θ = 1 - 2sin²θ
cos2θ = [tex]1-2(\frac{15}{17})^2[/tex]
cos2θ = 1 - [tex]\frac{450}{289}[/tex]
cos2θ = [tex]\frac{289-450}{289}[/tex]

First, you divide 12 by 3, giving you 4.
Then you divide a^3 by a^2, which is basically just subtracting the exponents, giving you a. Do the same with the rest of the variables. That’s how you get 4ab^2.

A rectangle lengths 12m and 17m and is dilated using the dilation (x, y) -> ( 0.4 x, 0.4y). What is the perimeter of the dilated rectangle?
Answers
Answer:
Perimeter of the dilated rectangle = 23.2 m
Step-by-step explanation:
If a point is dilated by a scale factor = k
Coordinates of the image point after dilation will follow the rule,
(x, y) → (kx, ky)
From the given rule,
(x, y) → (0.4x, 0.4y)
Which reveals that the figure has been dilated by a scale factor = 0.4
Length of the rectangle = 12 m
Width of the rectangle = 17 m
If the given rectangle is dilated by a scale factor of 0.4,
Length of the image rectangle = 12 × 0.4 = 4.8 m
Width of the image rectangle = 17 × 0.4 = 6.8 m
Perimeter of a rectangle = 2(length + width)
Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)
= 23.2 m
