Answer:
Measure of each one of the vertical angles = 30 degrees.
Step-by-step explanation:
Vertical angles are equal and opposite. If we have two vertical angles it means that both angles are equal .
As both angles are equal let both the angles be represented by x
Their sum is given by
x+x= 60 degrees
2x= 60 degrees
x= 60/2 degrees
x= 30 degrees
Measure of each one of the vertical angles = 30 degrees.
What is the equation in slope-intercept form of the line that crosses the x-axis at 21 and is perpendicular to the line represented by y = 7/2x-13
Given:
A line is perpendicular to the line [tex]y=\dfrac{7}{2}x-13[/tex].
The line passes through the x-axis at 21.
To find:
The equation of the line in slope intercept form.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
The given line is:
[tex]y=\dfrac{7}{2}x-13[/tex]
So, the slope of this line is [tex]\dfrac{7}{2}[/tex].
The product of slopes of two perpendicular lines is -1.
Let m be the slope of required line. Then the slope of the required line is:
[tex]m\times \dfrac{7}{2}=-1[/tex]
[tex]m=-\dfrac{2}{7}[/tex]
The line passes through the x-axis at 21. It means the line passes through the point (21,0). So, the equation of the line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-0=-\dfrac{2}{7}(x-21)[/tex]
[tex]y=-\dfrac{2}{7}(x)-\dfrac{2}{7}(-21)[/tex]
[tex]y=-\dfrac{2}{7}x+6[/tex]
Therefore, the equation of the required line is [tex]y=-\dfrac{2}{7}x+6[/tex].
Function f (x) = 25x/x + 3 has a discontinuity at x = –3. What are Limit of f (x) as x approaches negative 3 minus and Limit of f (x) as x approaches negative 3 plus?
Answer:
x approaches negative 3 to the right: [tex]lim_{x\to -3^{+}}=-\infty[/tex]
x approaches negative 3 to the left: [tex]lim_{x\to -3^{-}}=\infty[/tex]
Step-by-step explanation:
The function we have is:
[tex]f(x)=\frac{25x}{x+3}[/tex]
We have an asymptote at x = -3.
The limit of the function when x approaches negative 3 to the right will be:
[tex]lim_{x\to -3^{+}}=\frac{25x}{(-3)+3}=-\infty[/tex]
It is because the function is decreasing from right to left.
And the limit of the function when x approaches negative 3 to the left will be:
[tex]lim_{x\to -3^{-}}=\frac{25x}{(-3)+3}=\infty[/tex]
It is because the function is decreasing from left to right.
I hope it helps you!

Vendí por 30€ a la cual le había incrementado el 12% una prenda de ropa. Calcula el precio de la prenda antes del incremento.
Answer:
18€
Step-by-step explanation:
Given data
Selling price= €30
increase= 12%
Cost price= ???
We know that
% increase= selling price- cost price/cost price*100
let the cost price be x
12= 30- x/x*100
cross multiply
12*100= (30- x)100
1200= 3000-100x
1200-3000=-100x
-1800=-100x
x= 1800/100
x= 18
Hence the price before the increase is 18€

The national interest rate for savings accounts is 0.04%. I put $2,000 in my savings account for 40 years. How much interest will I earn?
Answer: $32.25
Step-by-step explanation:
Assuming this is compound interest, the value of the investment after a period of time can be calculated with the future value formula:
Value = Investment * ( 1 + rate) ^ no. of periods
Value ₄₀ = 2,000 * ( 1 + 0.04%)⁴⁰
Value ₄₀ = $2,032.25
Interest earned = Value at 40 years - Initial investment
= 2,032.25 - 2,000
= $32.25

For each expression, write an equivalent expression that uses only addition: a. 20 - 9 + 8 - 7 b. 4x - 7y - 5z + 6 c. -3x - 8y - 4 - 8/7z
Answer:
a. =11+ 1
b. =4x+ (-7y) + (-5z) +6
c. (-3x) + (-8y) +(-4)+(-8/7z)
Step-by-step explanation:
a. 20 - 9 + 8 -7
=11+ 1 ( this is obtained by solving)
b. 4x - 7y - 5z + 6
=4x+ (-7y) + (-5z) +6
We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.
c. -3x - 8y - 4 - 8/7z
-[ 3x+8y+4+8/7z]
or
(-3x) + (-8y) +(-4) +(-8/7z)
The minus sign is taken as common leaving the expression with the plus only.
It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.
The expressions are a sum after the negative sign is marked with the terms. It shows that the negative terms are being added.

Answer:
if u don't want them to have your insta/snap, tell them that you don't like sharing them. I just wouldn't respond after that
If they are bothering you say "Thank you for being nice to me, I am going to say this in the most the nicest way possible, but you're kind of bothering me right now. If you keep messaging me/ bothering me I'm going to have to block you" or you could say "Please stop asking me for my insta/snap if you keep asking me I am going to have to block you. Thank you have a nice day :)"
you could say something like that

Is the proportion of the female population age 60 or older in country A greater than the proportion of the female proportion age 6 or older in country B
Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.

Answer: 12
Step-by-step explanation:
Answer:
35.8
Step-by-step explanation:
Triangle adds up to 360 degrees
5y+4y+3+y-1=360
10y+2=360
-2 -2
10y=358
divided both sides by 1o
y=35.8
Write in standard form:
y =
O A. 3y = 2x – 18
B. 2r - 3y = 18
OC. 3y = 2x - 6
OD. 2x – 3y = 6

what is the length of the hypotenuse,c ? 3m 5m
Answer:
square root of 34
Step-by-step explanation:
ok so S is for Squared
Cs= As+Bs
5s+3s= Cs
25+9=34
Cs=34
C= square root of 34
to get C we need to square root Cs
square root of 34
so C is 5.83

find the value of x. (picture)
Answer:
x = 23
Step-by-step explanation:
Remember, angles in a triangle add up to equal 180
That being said we can create an equation to solve for x
180 = 110 + 35 + x + 12
now we solve for x
step 1: combine like terms
110 + 35 + 12 = 157
now we have 180 = 157 + x
step 2 subtract 157 from each side
180 - 157 = 23
157 - 157 cancels out
we're left with x = 23
