Answer: I think the answer would be (2, -1)

Answer:

C. 574.53

Step-by-step explanation:

Option C) is correct work done = 574.53.

Force = 15 pounds
distance = 50 feet
Ф = 40°

work done is product of force and cosine of displacement.

work done = force x displacement x cosФ
= 15 x 50 x cos40
= 15 x 50 x 0.76
= 574.53

Thus the required work done is 574.53 to pull the wagon.

2,2,4,5,11,12

the median is 5

Answer:

2, 2, 4, 5, 11, 12 (put the numbers from least to greatest)

since it's an even set of numbers, the median is between two of the numbers. so find where the middle is by counting how many numbers you have, and then dividing by 2. in this case it's 3, so there should be 3 values on either side of the median. so the median is between 4 and 5. So you add those two values together and divide by 2 (because that's how many numbers you added) and you get 4.5 as your median.

Step-by-step explanation:

He increased by 10% because of 80% to 90% is 10%

So, the Answer  is A

Answer:

12.5%

Step-by-step explanation:

The question is asking for the percent increase of 80%. So how much of 80% was the new percentage (90%) increased by.

First, find the difference 90-80=10

Then find the percent of 80 that the difference is.

10/80=0.125

0.125 in a percent form is 12.5%

So, there was a 12.5% increase.

A. 32.8%

Step-by-step explanation:

Blake's incomes are $3,200 each month.

His debts are:

$600 per month for housing

$300 per  month for a car loan

$150 per month in  other debt payments

Total payments: $600+$300+$150=$1,050

The debt-to-income ratio is calculated by:

[tex]\displaystyle r=\frac{1,050}{3,200}\cdot 100\%[/tex]

r = 32.8%

Dividing both sides by MK yields

[tex]\boxed{Y=\frac{V}{MK}}[/tex]

The 340 liters of leaves did Adam rake.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

Let X = the liters of leaves that Adam raked.

We have to find How many liters of leaves did Adam rake.

According to given question we have

Convert 5.0% into a decimal by moving the decimal point two spaces to the left we get

Then Tapiwa raked X + .05X liters of leaves is equal to 1.05X liters of leaves  is equal to 357.

Divide both sides by 1.05

X = 340 liters

Therefore, the 340 liters of leaves did Adam rake.

The line which shows another way to name the ray LR is line: LD.

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

Collinear points can be defined as three or more points that all lie on the same straight line (single line). Based on the geometric figures shown in the image below, the three collinear points include the following:

The distance between (-8,0) and (-5,3) in the coordinate plane is 9 units.

Given that the coordinates of points in the coordinate plane are (-8,0) and (-5,3).

We are required to find the distance between the given points.

Distance is basically a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to physical length or an estimation based on other criteria.

Distance between (-8,0) and (-5,3)=[tex]\sqrt{(-5+8)^{2} +(3-0)^{2} }[/tex]

Answer:

Linear

Step-by-step explanation:

You can simplify the equation by distributing the 9 in:

y = 18x  ⇒  And this equation is indeed linear

So, that means that y = 9(2x) is linear

Hope this helps! :)

y = 9(2x) is a linear function as the function given exactly one output for one input.

Given that,
To determine whether the given expression is a linear function or nonlinear function,

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The given function y = 9(2x)
Simplifying the given function,
y = 18x
Above relation shows that y has linear relationship with x,

Thus, y = 9(2x) is a linear function as the function gives exactly one output for one input.
