Answer:A=15 B=7 c=7 Clare's cousin is7
Step-by-step explanation:
Angle A and angle B are supplementary angles. If
angle B is 30° more than four times angle A, find
angle A and angle B.
Answer:
Angle A is 30
Angle B is 150
Step-by-step explanation:
So we have the supplementary angles A and B. In other words:
[tex]A+B=180[/tex]
We are also told that Angle B is 30 more than four times Angle A. In an equation, this is:
[tex]B=30+4A[/tex]
We now have a system of equations. Solve by substitution of B into the first equation:
[tex]A+B=180[/tex]
[tex]A+(30+4A)=180[/tex]
Combine like terms:
[tex]5A+30=180[/tex]
Subtract 30:
[tex]5A=150[/tex]
Divide by 5:
[tex]A=30[/tex]
So, Angle A is 30 degrees.
And since the angles are supplementary, this means that Angle B is 180 minus 30 or 150 degrees.

why isnt 16:14 equivlant to 64:60
Answer:
The scalar used does not exist in the real number system.
Step-by-step explanation:
The ratio 16:14 is not equivalent to the ratio 64:60 because the scalar used does not exist in the real number system.
Note, that the ratio 64:60 can be scaled down by 4 to be the ratio 16:15, which is not the ratio 16:14.
In order to scale 64:60 to 16:14 or vise versa, you'd have to use a number that simply does not exist in the real number system.
Cheers.
Hi May I know how to solve this?
Answer:
k = 3/4
Step-by-step explanation:
Parallel lines have the same slope so first, we need to find the slope of 8x + 6 = 2y. To do so, we can do the following:
8x + 6 = 2y
2y = 8x + 6
y = 4x + 3 (This is now in slope intercept form - y = mx + b where m = slope and b = y-int.)
Therefore, the slope is 4. Now, we can do:
3x = ky - 10
3x - 10 = ky
(3x / k) - (10 / k) = y
y = (3x / k) - (10 / k) (where k ≠ 0)
Now that the second line is in slope-intercept form, we can set the two x terms equal to each other, therefore:
3x / k = 4x
3x = 4x * k
3x / 4x = k
k = 3/4

The function h(x)=4/3x-1 represents the composite h(x)=f(g(x)).if f(x)=2x-1,what is g(x)
Answer:
[tex]g( x) = \frac{2}{3}x[/tex]
Step-by-step explanation:
Given:
Composite Function:
[tex]h( x)=f( g( x))[/tex]
Also,
[tex]h( x)=\frac{4}{3}x-1[/tex]
To find:
[tex]g( x ) = ?[/tex]
Solution:
First of all, let us learn about a composite function.
Composite function [tex]f( g( x))[/tex] means to write [tex]g( x)[/tex] in place of [tex]x[/tex] in the function [tex]f( x)[/tex].
Let [tex]g( x) = y[/tex]
So, [tex]f( g( x))[/tex] = [tex]f( y )[/tex].
Therefore,
[tex]h( x) =f( g( x)) = f( y)[/tex]
So, [tex]f( y) = 2y-1[/tex]
We have to solve for [tex]y[/tex] in terms of [tex]x[/tex] to find the value of [tex]g(x)[/tex]:
[tex]\Rightarrow \frac{4}{3}x-1 = 2y-1\\\Rightarrow 2y=\frac{4}{3}x\\\Rightarrow y = \frac{2}{3}x[/tex]
Hence, the answer is [tex]g( x ) = \frac{2}{3}x[/tex].
Checking whether the answer is correct or not:
[tex]f( g( x)) = f( \frac{2}{3}x) = 2\times \frac{2}{3}x -1 = \frac{4}{3}x-1[/tex]
which is [tex]h( x)[/tex].
Hence, our answer [tex]g( x ) = \frac{2}{3}x[/tex] is correct.
The g(x) of the function is:
g(x) = (2/3)x
How to find what g(x) is?A function is a relationship between inputs where each input is related to exactly one output.
Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
We have:
h(x) = (4/3)x - 1
h(x) = f(g(x))
f(x) = 2x - 1.
Thus, we can say:
h(x) = f(g(x)) = 2*g(x) - 1
(4/3)x - 1 = 2g(x) - 1
(4/3)x - 1 + 1= 2g(x)
(4/3)x = 2g(x)
(4/3)x * 1/2 = g(x)
(2/3)x = g(x)
g(x) = (2/3)x
Therefore, g(x) = (2/3)x.

Solve -4(x + 1) – 3 = -3(x - 4).

Answer:
We have this equation:
-4(x+1) - 3 = -3(x-4)
First of all, we solve the paretheses:
-4x - 4*1 - 3 = -3x - (-3*4)
-4x - 4 - 3 = -3x + 12
-4x -7 = -3x + 12
We sum 7 on both sides and 3x on both too:
-4x - 7 + 7 + 3x = -3x + 12 + 3x + 7
-4x + 3x = 12 + 7
-x = 19
x = -19
Now we can verify:
-4(-19+1) - 3 = -3(-19-4);
-4(-18) - 3 = -3(-23);
72 - 3 = 69 (TRUE)

Answer:
[tex]\bold{\dfrac{6}{7}}[/tex]
Step-by-step explanation:
Given ratio is:
8 gal to [tex]9\frac{1}3[/tex] gal
To find:
Ratio in Lowest form with whole numbers in numerator and denominator.
Solution:
First of all, let us convert [tex]9\frac{1}3[/tex] to simple [tex]\frac{p}{q}[/tex] form:
Formula:
[tex]a\dfrac{b}{c} = \dfrac{a\times c+b}c[/tex]
Using the formula, we get:
[tex]9\dfrac{1}{3} = \dfrac{9\times 3+1}{3} = \dfrac{28}{3}[/tex]
Now, let us have a look at the ratio:
[tex]8 : \dfrac{28}{3}[/tex]
Any ratio, [tex]p:q[/tex] can be written as [tex]\frac{p}{q}[/tex].
Writing given ratio as per above:
[tex]\dfrac{8}{\dfrac{28}{3}}\\\Rightarrow \dfrac{8 \times 3}{28}\\\Rightarrow \dfrac{2\times 3}{7}\\\Rightarrow \bold{\dfrac{6}{7}}[/tex]
Therefore, the answer is
[tex]\bold{\dfrac{6}{7}}[/tex]

A large western state consists of 3129 million acres of land. Approximately 55% of this land is federally owned. Find the number of acres that are not federally owned
Answer:
1408.5 acres
Step-by-step explanation:
If 55% of the land is federally owned, then 100 - 55 = 45% of the land is not federally owned.
We need to find how many acres are not federally owned, in other words, we need to find how many acres represent 45% of the total 3129 acres. So, to do this we can apply a rule of three:
3129 acres ---- 100%
x acres ------ 45%
[tex]x=\frac{(3129)(45)}{100} =3129(0.45)= 1408.05[/tex]
Therefore, the total of acres that are not federally owned are 1408.5 acres.
