Answer:
A: ∠WXZ = 87°; ∠ZXY = 73°
Step-by-step explanation:
Ray XZ divides the angle WXY into parts that have a sum equal to the whole.
(7x-4)° +(5x+8)° = 160° . . . . . whole is sum of parts
12x = 156 . . . . . . . . . . . . . divide by °, subtract 4
x = 13 . . . . . . . . . . . . . . divide by 12
∠WXZ = (7x -4)° = (7·13 -4)° = (91 -4)° = 87° . . . . . matches choice A
Find the inverse of the function: f(x)=3x−6
A f−1(x)=−2/3x
B f−1(x)=1/3x+2
C f−1(x)=−1/3x+12
Answer:
B. [tex] {f}^{ - 1} (x) = \frac{1}{3} x + 2[/tex]
Step-by-step explanation:
[tex]f(x) = 3x - 6[/tex]
[tex]y = 3x - 6[/tex]
[tex]x = 3y - 6[/tex]
[tex]3y - 6 = x[/tex]
[tex]3y = x + 6[/tex]
[tex]y = \frac{1}{3} x + 2[/tex]
[tex]\boxed{\green{ {f}^{ - 1} (x) = \frac{1}{3} x + 2}}[/tex]
The rectangles are similar. Find x.

What is 3.5 divided by 7
Answer:
1/2 or 0.5
Step-by-step explanation:
....
The solution for 3.5 divided by 7 is,
⇒ 70
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 3.5 divided by 7
Now, We can write as;
⇒ 3.5 divided by 7
⇒ 3.5 ÷ 7
⇒ 35 / 70

Is 0.875 irrational or rational and why?
7. Given directed line segment RT below, find the coordinates of S such that the ratio of RS to ST is 5:1. Plot point S
A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
The coordinate of S is: [tex](6,\frac{8}{3})[/tex]Given that:
[tex]RS : ST = 5 : 1[/tex]
The coordinates of RT are not given. So, I will solve using a general explanation.
When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:
[tex]S = [\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
Assume the coordinate of R and T is:
[tex]R = (1,6)\\T = (7,2)[/tex]
[tex]RS : ST = 5 : 1[/tex] means:
[tex]m:n = 5:1[/tex]
So, point S is:
[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]
[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]
[tex]S = [6,\frac{8}{3}][/tex]
Hence, if the coordinates of R and T are:
[tex]R = (1,6)\\T = (7,2)[/tex]
And the line ratio is:
[tex]m:n = 5:1[/tex]
The coordinate of S is:
[tex]S = [6,\frac{8}{3}][/tex]

How do you do a negative power?
Answer:
A negative exponent is defined as the multiplicative inverse of the base, raised to the power which is opposite to the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents. For example, (2/3)-2 can be written as (3/2)2.

What is -1 7/8 + -2 1/4? Please explain why and a step by step :).
9514 1404 393
Answer:
-4 1/8
Step-by-step explanation:
Many people find it easier to factor out -1, then do the addition. The fractions need a common denominator before they can be added. A suitable denominator that is a multiple of both 4 and 8 is 8.
The fraction 1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8.
__
So, the problem can be rewritten as ...
-(1 7/8 +2 2/8)
= -((1+2) +(7/8 +2/8))
= -(3 +9/8)
The fraction 9/8 is an improper fraction equal to 8/8 +1/8 = 1 1/8. Then the sum is ...
-(3 +1 1/8) = -4 1/8

If you have 3/12 of an orange, how many fourths do you have?
Answer:
Answer: one fourth
Fourth is a word that used to describe a number value of 1/4. To answer this question, you need to change the number you got (3/12) into x/4 form. To convert 12 into 4, then you need to divide the numerator and denominator with 3. The equation would be (3/3)/(12/3)= 1/4.
To determine how much fourth the number has, you need to divide the result with 1/4. The calculation would be: (1/4)/ (1/4)= one fourth

Write 9 1/100 as a decimal number
Answer:
9.01
Step-by-step explanation:
9 1/100 = 9 + 1/100
1/100= 1 divded by 100
=9+0.01=9.01
the value of 9 1/00 in decimal, is 9.01
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given a number 9 1/100
in decimal, we can also write it as
9 1/100 = 9 +1/100
=> 9 1/100 = 9.01
therefore, in decimal the value of 9 1/100 is 9.01.
