Answer:
the number is 2.66
Step-by-step explanation:
[tex]6.7+5x=20[/tex]
Step 1. Subtract 6.7 from both sides
[tex]5x=20-6.7[/tex]
[tex]5x=13.3[/tex]
Step 2. Isolate the variable
[tex]\frac{5x}{5} =\frac{13.3}{5}[/tex]
[tex]x=2.66[/tex]
The number is 2.66
The product of 9 upon 7 and a number is 63. Find the number
Answer:
heyy Vrooo....
alr ans is 49
Step-by-step explanation:
see let number be x
so as per ques.. product of x and 9/7 = 9x/7
which is 63
so [tex]\frac{9x}{7}[/tex] = 63
9x = 63*7
x = [tex]\frac{63*7}{9}[/tex]
x = 7*7 = 49

Suppose that the function h is defined, for all real numbers, as follows.
Answer:
gsgdjdjchdvvdbdjzjsjsushsvvsvsvs I don't know
Answer:
see explanation
Step-by-step explanation:
h(- 3) with x = - 3, that is x ≠ 1 , then
h(- 3) = - [tex]\frac{1}{2}[/tex] (- 3) + 2 = [tex]\frac{3}{2}[/tex] + 2 = [tex]\frac{7}{2}[/tex]
h(1) with x = 1 , then
h(1) = 1
h(3) with x = 3, that is x ≠ 1 , then
h(3) = - [tex]\frac{1}{2}[/tex] (3) + 2 = - [tex]\frac{3}{2}[/tex] + 2 = [tex]\frac{1}{2}[/tex]

A car manufacturing company asked 1000 people to view their latest two-door coupe available in four colors (White, Black, Cherry, and Blue).The viewers were asked to list their color preferences in order form favorite. How many ways could the colors be ordered? Of the 1000 viewers, how many would you expect to choose the following preference order: White, Black, Cherry, and Blue?
The first choice can be aby one of the 4 colors.
For each of these . . .
The 2nd choice can be any one of the 3 remaining colors.
For each of these . . .
The 3rd choice can be either one of the 2 remaining colors.
So there are (4 · 3 · 2) = 24 different ways to order the colors.
If everybody you ask thinks the same way, you'd expect all of the possible combinations to be chosen equal numbers of times . . . that is, every choice would be chosen once in every group of 24 people.
In 1,000 people, there are (1000/24) = (41 and 2/3) groups of 24 people.
So you'd expect any one possible preference order to be chosen by 41 or 42 viewers, if all of the viewers think the same way, and their preferences are perfectly random.
Please solve if you can!

Which two ratios represent quantities that are proportional?
A. 25/28 and 5/7
B. 22/33 and 14/21
C. 16/13 and 13/16
D. 48/60 and 35/42
Answer:
B
Step-by-step explanation:
22/33 = 0.667
14/21 = 0.667
Since both quantities both have the ratio of 2:3, they are proportional
The other choices are not proportional
25/28 = 0.893
5/7 = 0.714
16/13 = 1.231
13/16 = 0.813
48/60 = .8
35/42 = .833

help please i need the answer to this
Answer:
140 degrees
Step-by-step explanation:
first start by making the given angles equal each other because they are congruent.
2x+28=6x+4
Subtract 4 on both sides
2x+24=6x
subtract 2x on both sides
24=4x
divide both sides by 4 to get x
24/4=4x/4
6=x
next to find the actual number of the angle, plug 6 back into either one of the equations. Im gonna use the first one.
2x + 28
2(6) + 28
12+28= 40
Now that we have the number, we already know that a full circle is 360 degrees so half a circle is 180.
Take 40 and subtract from 180
180-40= 140
Well, m∠1 and m∠3 are congruent by the Vertical Angle Congruent Theorem (VACT). This means that because the angles are opposite of each other, their angles are the same because they are formed by the same two intersecting lines.
Because of this, we can set m∠1 and m∠3 equal to each other:
m∠1 = m∠3
(2x + 28) = (6x + 4)
2x + 28 = 6x + 4
-4x + 28 = 4
-4x = -24
-x = -6
x = 6
Knowing that x equals 6, we can use this to find m∠2. By the Supplementary Angles Theorem (SAT), angles that are on the same line add up to equal 180°. To use the SAT, we need to plug x in to find m∠1 or m∠3, because they are both the same:
x = 6
m∠1 = (2x + 28)
m∠1 = 2(6) + 28
m∠1 = 12 + 28
m∠1 = 40°
m∠3 also equals 40°.
Now that we have the value for ∠1 (or ∠3), we can use the SAT:
m∠2 + m∠3 = 180 ← You could also use m∠1, because they both equal the same!
m∠2 + 40 = 180
m∠2 = 140°
So, the measure of ∠2 is 140°.

The value of x at -4 goes to more than one value of y- this is not a function
c.{(0,3),(−6,8),(−3,5),(0,−3),(7,11)}
The value of x at 0 goes to more than one value of y- this is not a function

Answer:
a) 72
Step-by-step explanation:
The rightmost digit, 5, is in the ones place, so its value is 5.
The next digit to the left, the 4 is in the sixes place, so its value is 4 * 6 = 24.
The next digit to the left, the 2, is in the 36 place, so its value is 2 * 36 = 72.

Which equation is a direct variation function?
y = x
y = 4
y = x2
y = 1/4 x + 2
Answer:
Two choices are correct answer.
y = x and y = 1/4 x
Step-by-step explanation:
We have given four equations.
We have to choose the equations that are direct variation function.
Direct variation function is defined as the relation where one variable vary constant times to the other variable.
let two variables are x and y.
y = kx where k is constant.
Comparing given equation , we notice that
y = x is direct variation function where k = 1.
y = 1/4 x is direct variation function where k = 1/4.

Consider the graph of the function below.
Which statement about the graph below is incorrect?
A. The degree of the polynomial is even.
B. There is a positive leading coefficient.
C. There is one relative minimum.
D. There is one relative maximum.
a
A
b
B
С
d
D
Answer: A) The degree of the polynomial is even
We can determine this by noticing that the end behavior is different on both sides. The left end goes downward while the right end goes upward. This opposing nature indicates we have an odd degree function like a cubic. If this was an even degree function, then the left end must also point upward to mirror the right end. That's why choice A is the final answer.
Choice B can be ruled out since it's a true statement. This is because the right end behavior goes to positive infinity. Such end behavior is tied to positive leading coefficients (whether even or odd functions, it doesn't matter).
Choice C is also true and can be ruled out because this function curve does have one relative minimum. It's the location where the curve bottoms out in the valley at around x = 3.5 or so. It's the lowest point in the neighborhood/interval of points.
Choice D can be ruled out for similar reasons as choice C, except this time we're looking at the highest point in a certain neighborhood. That highest point occurs somewhere between x = 1.5 and x = 2 where the peak of the hill is located.
To rephrase those last three paragraphs: choices B through D are true statements, so they can be ruled out.
