Answer:
No, these ratios aren't proportional
Step-by-step explanation:
4:16 base ratio is 1:4
12:16 base ratio is 1:1.333333333

building, with the bottom of the ladder standing on
level ground 9 feet from the base of the building. How
high up the wall does the ladder reach?
Answer:
26.5ft
Step-by-step explanation:
Consider:
AB=25 ft
BC =9 ft
AC=?ft
[tex](AB)^2 + (BC)^2 = (AC)^2\\25^2+ 9^2=(AC)^2\\(AC)^2= 625+81\\[/tex]

Please help with all of them!
Answer:
See the first 3 problems solved below.
I added the next 3 problems.
Step-by-step explanation:
1.
2x + 4x = 180
6x = 180
x = 30
2x = 2(30) = 60
4x = 4(30) = 120
2.
3x + 6x = 180
9x = 180
x = 20
3x = 3(20) = 60
6x = 6(20) = 120
3.
8x + 10x = 180
18x = 180
x = 10
8x = 8(10) = 80
10x = 10(10) = 100
4.
7x + 8x = 180
15x = 180
x = 12
7x = 7(12) = 84
8x = 8(12) = 96
5.
2x + x = 180
3x = 180
x = 60
2x = 120
6.
2x + 2x = 180
4x = 180
x = 45
2x = 2(45) = 90
The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The angles ∠GFH = x and ∠CBD = 2x.
From the figure, the angles ∠GFH and ∠CBD are supplementary angles.
∠GFH + ∠CBD = 180°
x + 2x = 180°
3x = 180°
x = 60°
Then the measure of the angles ∠GFH and ∠CBD will be
∠GFH = 60°
∠CBD = 2 × 60°
∠CBD = 120°
The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.

on Saturday five girls held a car wash to earn money for each car they charged $6 the girls washed a total of 22 cars and collected an extra $10 in tips if they divide the money equally how much will each girl receive
This is due at 4:20 Can you please help
Answer:
$28.40
Step-by-step explanation:
First let's find how much they earned from washing the cars. They charged $6 for each car and washed 22 so 6x22=$132 from washing cars. After that they earned 10 more dollars so we have to add that. 132+10=$142 earned in total. Then we have to divide this total income between all of the girls. 142/5=$28.40 for each girl.

Need help finding the coordinate rule
Answer:
(x, y ) → (x - 4, y - 3 )
Step-by-step explanation:
consider the coordinates of A and A'
A (0, 4 ) , A' (- 4, 1 )
0 to - 4 in the x- direction means subtracting 4
4 to 1 in the y- direction means subtracting 3
then translation rule is
(x, y ) → (x - 4, y - 3 )

Help! How do I do this?
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
and the sum of all angles around one point at one side of a line is also airways 180° (because you can imagine that point to be the center of a circle, and the line would cut that circle in half = 180° for every half).
in the triangle LKM we know 2 angles already :
angle 1 = 44°
angle K = 90° (right angle).
so, angle 2 = 180 - 90 - 44 = 46°
and so, angle 5 = 180 - 46 = 134°.
as the angles around point L on line KL are the angles 2 and 5.
angle 5 = 134°

Hi! Hope you are having a nice day!
In order to make x the subject, we need to solve for x.
It's easy, right?
We have
y=x+6
Move x to the left. Be sure to use the opposite operation.
y-x=6
Now, move y to the right:
-x=6-y
x=-6+y
or
x=y-6
There's an easier way:
y=x+6
y-6=x
x=y-6 (See? We ended up with the same answer :) )
Hope you could understand everything.

What is the number of degrees of freedom of a t-test?For a sample of size n, the number of degrees of freedom is given by:
df = n - 1
When there are m samples, the amount of degrees of freedom is m multiplied by the sum of degrees of freedom of each sample.
In this problem, there are 2 samples with 6 - 1 = 5 df, hence:
