Answer:
x=30
Step-by-step explanation:
So we know its a supplementary angle which is angles athat add up to 180 degrees since its a straight line.
Make an equation: 60+60+2x=180COmbine like terms
120+2x=180
subtract 120 on both sides
2x=60
x=30

Using the pythagorean Theorem formula (a^2 + b^2 + c^2) Plug in A and B (13, and 13).
(13)^2 + (13)^2 = c^2
13 • 13 + 13 • 13 = c^2
169 + 169 = c^2
v/338 = v/c^2 (square root them both)

What is the equation of a line that is perpendicular to -x + 2y =4 and passes through the point (-2, 1)
Answers
Answer:
y = -2x - 3
Step-by-step explanation:
-solve for y: y = 1/2x + 2
-perpendicular equals opposite slope: -2
-plug in the point: (1) = -2(-2) + b
1 = 4 + b
b = -3
put it all together: y = -2x - 3
Write in y=mx+b form
Answers
Answer:
y = -2/3x
Step-by-step explanation:
To write in y=mx+b form, you need the y-intercept (b) and the slope (m).
The y-intercept is the point the line crosses the y-axis. This line crosses the y-axis of (0, 0). This makes the y-intercept equal to 0.
The slope is the rise of the line over the run of the line. Pick two points from the line. It doesn't matter which ones, you will get the right answer regardless.
I picked (0, 0) and (-3, 2). Subtract the x-values from each other, and subtract the y-values from each other.
-3 - 0 = -3 (x)
2 - 0 = 2 (y)
Divide the y by the x to find the slope.
2/-3 = -2/3
Plug in the slope and y-intercept into the equation.
y = mx + b
y = -2/3x + 0
y = -2/3x

Answer:
1. Unbiased sample.
2. Self-selected sample.
3. Stratified sample.
4. Systematic sample.
5. Convenience sample.
6. Biased sample.
Step-by-step explanation:
1. Unbiased sample: sample where every member of the population has an equal chance of being selected.
For example, a researcher randomly selecting a shopping mall and questioning the customers coming there.2. Self-selected sample: sample where members volunteer to take part.
For example, a researcher uploading a questionnaire online and then requesting for brainly members to take part.3. Stratified sample: members are selected from the different subgroups within a population.
For example, when a geographical region is stratified into subgroups by climate, habitat, soil type or elevation. A population grouped by males or females.4. Systematic sample: sample members are selected through the use of a rule.
For example, a researcher selecting the 10th house on a particular street.5. Convenience sample: sample where representatives are easily accessible.
For example, a researcher using a social media poll such as Twitter polls.6. Biased sample: sample not representative of the entire population.
For example, a researcher selecting only females when trying to determine the best cook in a class.Answer:

Mr Avalon's cousin's Kurt and rod started their own business curtain rods curtain rods they sell curtain rods for $5 each they rent a store in the mall for their business for $2,500 per month how many curtain rods must they sell to earn a profit of$ 3750?
Answers
Answer:34.3 N and 15.7 N
Explanation:
= force on the left end of the rod
= force on the right end of the rod
M = mass of Halloween decoration = 3 kg
= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N
m = mass of rod = 2.1 kg
= weight of the rod = mg = 2.1 x 9.8 = 20.6 N
From the force diagram, using equilibrium of torque about A
(AB) + (AC) = (AD)
(29.4) (21) + (20.6) (57) = (114)
= 15.7 N
Using equilibrium of force along the vertical direction
+ = +
15.7 + = 29.4 + 20.6
= 34.3 N

Mia wants to borrow £6000 and repay it, with interest, after two years. she sees two offers for loans: offer 1 compound interest 3% per year offfer 2 compound interest first year 1% second year 3% mia says, iwill payback the same amount because the average of 1% and 5% is 3% is she correct?
Answers
Answer:
she is wrong, offer 2 results in lower interests
Step-by-step explanation:
total amount paid if offer 1 is accepted:
$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40
she will pay $365.40 in interests
total amount paid if offer 2 is accepted:
($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363
she will pay $363 in interests
Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40
A student concluded that 0.5(6x+4) = 3x+4 has no solution. Which statement BEST describes the student's conclusion? A.) The conclusion is correct because the coefficient before the variable is equivalent. B.) The conclusion is incorrect because there is exactly one solution to the equation. C.)The conclusion is correct because, when simplified, both sides of the equation are equivalent. D.)The conclusion is incorrect because there are two solutions to the equation.
Answers
Answer:
The conclusion is correct because the coefficient before the variable is equivalent.
Step-by-step explanation:
The given equation is :
0.5(6x+4) = 3x+4
First, we will solve the equation.
3x+2=3x+4
A student concluded that the above equation has no solution. The conclusion is correct because the coefficient before the variable is equivalent. Hence, the correct option is (a).

Answer:
y=-1/8x +4
Step-by-step explanation:
1. First, write the equation in point-slope form: y-y1=m(x-x1)
y-1=-1/8(x-24)
2. Distribute -1/8 to x and -24
-1/8 times x = -1/8x
-1/8 times -24 = 3
y-1=-1/8x+3
3. Add 1 to both sides
y=-1/8x +4

Step-by-step explanation:
The graph of the inverse of a function is its reflection in the line y=x. In the attached, that line is shown as a dashed yellow line. The inverse function is shown as a blue line.
__
One way to plot the inverse function of a line is to swap the x- and y-coordinates of the line's intercepts.
In A, the x-intercept is about 10, and the y-intercept is about -4. For the inverse function, the y-intercept will be 10 and the x-intercept will be -4.
In B, the x- and y-intercepts of the function are -6 and 6, respectively. For the inverse function, they will be 6 and -6, respectively.
Answer:
In A, the x-intercept is about 10, and the y-intercept is about -4. For the inverse function, the y-intercept will be 10 and the x-intercept will be -4.

Kelsey's favorite crackers are available in two different sizes. The two different size boxes and their prices are shown. Crunchy Crisp Crackers Crunchy Crisp Crackers Regular Size 10 ounces Large Size 22 ounces $1.75 $3.75
Answers
Answer:
[tex]Rate = \$0.175/0z[/tex] --- Regular
[tex]Rate = \$0.1705/0z[/tex] --- Large
Step-by-step explanation:
Required (Missing from the question)
Determine the price per ounce
From the question, we have the following given parameters:
For the regular size:
Size = 10oz
Price = $1.75
For the large size:
Size = 22oz
Price = $3.75
The price per ounce is calculated using
[tex]Rate = \frac{Price}{Size}[/tex]
For the regular size:
[tex]Rate = \frac{\$1.75}{10oz}[/tex]
[tex]Rate = \$0.175/0z[/tex]
For the large size:
[tex]Rate = \frac{\$3.75}{22oz}[/tex]
[tex]Rate = \$0.1705/0z[/tex]
