Answer:
r = r
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80 = 4r + 80
- 80 - 80
4r = 4r
4 4
r = r
Answer:
no solution
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80= 4r+ 80
-4r -4r
80= 80

Answer:
c. x = 1
Step-by-step explanation:
c. The Pythagorean theorem applies. The square of the hypotenuse is the sum of the squares of the other two sides.
2² = x² +(√3)²
4 = x² +3
1 = x² . . . . . . subtract 3

what is the Greatest common factor shared by 80 and 100
Answer:
20
Step-by-step explanation:
[tex]GCD(80,100)\\\\\longrightarrow 80=2^4\cdot5\\\\\longrightarrow 100=2^2\cdot5^2\\\\[/tex]
so for two is
[tex]2^2[/tex]
and for 5 is
[tex]5[/tex]
so we multiply both

Step-by-step explanation:
Calculate RS using the distance formula
d = [tex]\sqrt{(x_{2 -x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = R(0, a) and (x₂, y₂ ) = S(b, c) , thus
RS = [tex]\sqrt{(b-0)^2+(c-a)^2}[/tex]
= [tex]\sqrt{b^2+(c-a)^2}[/tex]
Following are the calculation to the distance of rs:
Given:
Please find the question.
To find:

Solution:
Using the formula of distance:

points:
[tex]\to R=(0,a)\\\\\to S=(b,c)[/tex]
[tex]\to (X_1, y_1) = R(0, a) \\\\ \to (x_2, y_2 ) = S(b, c)[/tex]
Calculate RS distance by using the above formula:
[tex]\to RS=\sqrt{(b-0)^2+(c-a)^2}\\\\\to RS=\sqrt{(b)^2+(c-a)^2}\\\\\to RS=\sqrt{(b)^2+(c-a)^2}\\\\[/tex]

Maurice's shirt has five buttons that are vertically arranged and equally spaced. His shirt is shown in the photo below. The first and last buttons are 15.25 inches apart when measured from the top of the first button to the top of the last button. What is the distance, in inches, between the top two buttons on his shirt, from the top of one to the top of the other? Round your answer to the nearest tenth.
Answer:
The distance between the top two buttons on his shirt is 3.8 inches.
Step-by-step explanation:
Maurice's shirt has 5 buttons. Distance between first and last button is 15.25.
If we see, they would be arranged like

They are equally spaced between each button.
So, there are 4 equal spaces between the buttons.
Distance between each two consecutive buttons =[tex]\frac{15.25}{4}[/tex] =3.8125
So, distance between the top two buttons on his shirt is 3.8 inches.

Alex is x years old. Addison is y years younger. Find their combined age in 10 years’ time.
Answer:
x+10-y
Step-by-step explanation:
i'm not 100% sure about this response, but i'd assume the answer is like this for the following reasons:
alex is x years old, and 10 years have passed, meaning 10 years are added onto his age (x+10). addison is still the same amount of years apart from him in age, so you subtract y from that (x+10-y).

When x = -6, y = 7
Answer:

Answer: -103
Step-by-step explanation:
y=7 so 7x(-7)= -49 because a negative times a positive always equals a negative. Same thing for 9x. x=(-6) so 9x(-6)=-54. So (-49)+(-54)= -103

A flat screen tv at Best Buy costs $699 . The sales tax in Virginia is 5.3%. How much tax will you pay on the TV?
Answer:
736.05
Step-by-step explanation:699.00 x 5.3%=37.047
699.00 + 37.05 = 736.05
Answer:
$37.05
Step-by-step explanation:
$699 × 5.3%
We must convert 5.3% into just a decimal (not a percentage)
To do so, move the decimal to the left two places.
This would be 0.053
699 × 0.053 = 37.047
Although the exact number is 37.047, money is only paid within two decimals places, so let's round up to the nearest hundredth place
37.047 rounds up to 37.05
$37.05 is how much tax will be paid on the TV

Step-by-step explanation:
What is the equation of a line that is perpendicular to the line y = 2x + 4 and passes through the point (-2, 3)?
Answer:
[tex]y=-\frac{1}{2} x+2[/tex]
Step-by-step explanation:
The given equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptx and y are the corresponding coordinate points (x,y)The slope is 2:
When two lines are perpendicular, their slopes will be opposite reciprocals. Find the slope of the line perpendicular to the given equation:
[tex]m_{1}=2[/tex]
This can be seen as:
[tex]m_{1}=\frac{2}{1}[/tex]
Flip the fraction (reciprocal):
[tex]\frac{2}{1}[/tex] → [tex]\frac{1}{2}[/tex]
Now find the opposite:
[tex]\frac{1}{2}[/tex] → [tex]-\frac{1}{2}[/tex]
So the slope of the perpendicular line is:
[tex]m_{2}=-\frac{1}{2}[/tex]
Now make an equation written in point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
where:
m is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the corresponding coordinate points [tex](x_{1},y_{1})[/tex]Insert information:
[tex]y-3=-\frac{1}{2} (x-(-2))\\\\y-3=-\frac{1}{2} (x+2)[/tex]
Simplify to slope-intercept form. Solve for y:
Use the distributive property:
[tex]y-3=-\frac{1}{2}(x)-\frac{1}{2} (2)\\\\ y-3=-\frac{1}{2} x-1[/tex]
Add 3 to both sides to isolate the variable:
[tex]y-3+3=-\frac{1}{2} x-1+3\\\\y=-\frac{1}{2} x+2[/tex]

The number line below represents which combined inequality? (10 points)
number line with a closed circle on negative 6 and 5 with shading in between
x greater than or equal to −6 or x less than or equal to 5
x greater than or equal to −6 and x less than or equal to 5
x less than or equal to −6 and x greater than or equal to 5
x less than or equal to −6 or x greater than or equal to 5
Answer:
x is greater than or equal to −6 and x less than or equal to 5 (second option).
Step-by-step explanation:
This would be written as an "and" inequality; -6[tex]\leq[/tex]x[tex]\leq[/tex]5. Because the circle is closed on the number line, x is greater than or equal to −6 and x less than or equal to 5, and that's pretty much the answer!

Resistance is measured in units called ohms (symbol: Ω).
What is resistance?Resistance is a property of an electrical component that resists the flow of electric current through it.
We have,
Resistance is measured in ohms, which is the unit of electrical resistance. One ohm is the resistance value through which a current of one ampere will flow when a potential difference of one volt is applied across it.
Resistance is an important concept in electrical engineering and physics, as it is a fundamental property of electrical circuits and components.
