Answer:
88 \(cm^{2}\)
Step-by-step explanation:
We need to find the area of the rectangle and the triangle.
Area of the rectangle:
a = length x width
a = 11 x 6 = 66
Area of the triangle:
a = \(\frac{ b x h}{2}\) We need to find the base and height of the triangle. The base is the same length as the length of the rectangle: 11 and the height is 10 - 6 or 4
a = \(\frac{11 x 4}{2}\)
a = \(\frac{44}{2}\)
a = 22
Add the area of the rectangle and the triangle together. 66 + 22 = 88

Given N(-3,-7), O(-4,-2), P(1, -7), and Q(-2, y). Find y
such that NO|| PQ.
Answer:
y = 8
Step-by-step explanation:
Given N(-3,-7), O(-4,-2), P(1, -7), and Q(-2, y), you want to find y such that NO ║ PQ.
GraphWhen we plot the points, we see that point O is 1 unit left and 5 units up from point N. Point Q is on a line 3 units left of P, so it will need to be 3×5 = 15 units up from P in order for PQ to have the same slope as NO:
y = -7 +15 = 8
The value of y is 8; the point Q is (-2, 8).

mean marks of 100 students was 40.. It was discovered that 53 was misread as 83. Find the actual mean.
mean marks of 100 students was 40.. It was discovered that 53 was misread as 83. Find the actual mean.
Solution:-Total mean score = 40
\(mean \: = \frac{sum \: of \: observation}{number \: of \: observations} \)
sum of observations
= mean × no of observations
= 40×100
= 4000
After the replacement, sum of new observation will be
=4000-83+53
= 3970
mean of new the observation will be
\( = \frac{3970}{100} \)
\( = 39.7\)
[Hence, the actual mean is 39.7]
prove for all nonzero real numbers x and y, multinv(x*y) = (multinv x) * (multinv y)
multinv(x*y) = (multinv x) * (multinv y) {proved}
To prove that for all nonzero real numbers x and y, multinv(x*y) = (multinv x) * (multinv y), we will follow these steps:
Step 1: Understand the terms
Multinv(x) refers to the multiplicative inverse of x, which is the reciprocal of x (1/x).
Step 2: Write down the given equation
We are given that multinv(x*y) = (multinv x) * (multinv y).
Step 3: Replace the terms with their definitions
The multiplicative inverse of x*y is 1/(x*y). Similarly, the multiplicative inverse of x is 1/x, and the multiplicative inverse of y is 1/y.
Step 4: Plug in the definitions
1/(x*y) = (1/x) * (1/y)
Step 5: Verify if both sides of the equation are equal
Using the properties of fractions, we know that (1/x) * (1/y) is equal to 1/(x*y).
Thus, the given equation holds true:
multinv(x*y) = (multinv x) * (multinv y)

In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound. Donna bought two gallons of milk and some bananas for a total of $2.25 in 1947. How many pounds of bananas did she buy?
Answer:
Answer is 5 pounds of bananas
Step-by-step explanation:
Required milk:
Milk= 2 gallons
Milk cost per gallon=$0.75
so,
2*0.75
$ 1.5
total amount =$2.25
to calculate bananas
$2.25-$1.5=$0.75
per pound cost of bananas =$0.15
$0.75/$0.15
5 pounds of bananas
Dona bought 5 pounds of banana and 2 gallons of milk for a total of $2.25.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound.
Let,The cost of one gallon of milk is 'x' dollars and the cost of one pound of banana is 'y' dollars.
Also given Donna bought two gallons of milk and some bananas for a total of $2.25.
Therefore, 2(0.75) + 0.15y = 2.25.
0.15y = 2.25 - 1.5.
0.15y = 0.75.
y = 0.75/0.15.
y = 5.
So, Dona bought 5 pounds of bananas.

Choose the associated property
The Associative property is not displayed by any of the given equations.
The associative property of several binary operations in mathematics states that the outcome will not change if the parenthesis in an expression are rearranged.
The order in which the operations are carried out within an expression that has two or more instances of the same associative operator in a row doesn't matter as long as the order of the operands is left untouched.
Examples of associative property :
\({\displaystyle {\begin{aligned}(7+8)+1&=7+(8+1)=9\,\\5\times (3\times 7)&=(5\times 3)\times 7=24.\end{aligned}}}\)
The parentheses were rearranged on each line, but the expression values were left alone. It can be argued that "addition and multiplication of real numbers are associative operations" because this is true for addition and multiplication of all real numbers.
Here 8=8+0 displays additive identity property.
10×1=10 displays multiplicative identity
5+0=5 displays displays additive identity property.
\(5\times \frac{1}{5}=1\) displays multiplicative inverse property.
\(3+\frac{3}{4} =3+\frac{3}{4}\) displays reflexive property.
Hence no equation displays associative property.

Kierston needs to paint a wall of the youth center. She knows that 1 can of paint covers an area of 2.2 square meters. Kierston measures the wall using a meter stick as shown below. How many cans of paint must kierston buy to paint the wall of the youth center?
Answer:
See Explanation
Step-by-step explanation:
Given
\(1\ can = 2.2m^2\)
Required
Determine the number of cans for the wall
The dimension of the wall is not given. So, I will use the following assumed values:
\(Length=20m\)
\(Width = 44m\)
First, calculate the area of the wall
\(Area = Length * Width\)
\(Area = 20m * 44m\)
\(Area = 880m^2\)
If \(1\ can = 2.2m^2\)
Then \(x = 880m^2\)
Cross Multiply:
\(x * 2.2m^2 = 1 * 880m^2\)
\(x * 2.2m^2 = 880m^2\)
\(x * 2.2 = 880\)
Make x the subject
\(x = \frac{880}{2.2}\)
\(x = 400\)
400 cans using the assume dimensions.

ann gave 10% of her time to point i, 15% of her time to point ii, and 75% of her time to point iii. what does this division indicate?
Answer:
Point I and Point II may not need to be main points.
Ann's main points are not balanced.
Parallel structure will not work with Ann's speech topic.
Step-by-step explanation:
This division indicates that Ann prioritized Point III above Points I and II. Point III was allocated the most of Ann's time (75%), while Point I and II were each given 10% and 15%, respectively. This is a sign that Ann placed a higher priority on Point III.
In terms of the actual percentages, this could indicate a variety of things. It could mean that Ann felt Point III was more important than the other two points, or that Point III took more time to complete than the other two points. It could also mean that Ann was trying to achieve a specific ratio of her time dedicated to each point.
Regardless of the reasoning, this division of Ann's time shows that she placed a higher priority on Point III. This could mean that Point III was more important to her overall goal than the other two points, or that Point III required a larger amount of her time.
By understanding this division of Ann's time, we can gain insight into what she felt was important, and how she chose to prioritize her time. This can be used to better understand Ann's thought process and her overall goal.

(-4x-5)

Answer:
\(\boxed{x = -31}\)
\(\boxed{y = -62}\)
\(\boxed{z = -6}}\)
Step-by-step explanation:
There are a couple of properties of parallelograms that can help solve for the unknowns
The opposite angles of a parallelogram are congruent(equal)Consecutive angles are supplementary(add up to 180°)Using property 1 that opposite angles are equal we have:
-4x - 5 = 119
⇒ -4x = 119 + 5
⇒ -4x = 124
⇒ x = 124/-4
⇒ x = -31
Using property 2 that consecutive angles are supplementary on angles
(-y - 1)° and 119°:
(- y - 1) + 119 = 180
⇒ - y - 1 + 119 = 180
⇒ - y + 118 = 180
⇒ - y = 180 - 118
⇒ - y = 62
⇒ y = -62
Using property 2 for angles (-10z - 1)° and 119°
(-10z + 1) + 119 = 180
- 10z + 1 + 119 = 180
⇒ - 10z + 120 = 180
⇒ -10z = 180 - 120
⇒ -10z = 60
⇒ z = 60/-10
⇒ z = -6
The distance a body falls varies directly as the square of the time that it falls. If it falls 972 meters in 18 seconds, how far will it fall in 2 seconds?
Let's use the formula for direct variation to solve this problem. If a quantity varies directly as the square of another quantity, we can write:
distance = k * time^2
where k is a constant of proportionality. To solve for k, we can use the information given in the problem:
972 = k * 18^2
Simplifying this expression, we get:
k = 972 / 324 = 3
Now we can use this value of k to find the distance that the body falls in 2 seconds:
distance = 3 * 2^2 = 12 meters
Therefore, the body will fall 12 meters in 2 seconds.
