Answer:
9/10
Step-by-step explanation:
you can only add fractions when the denominator is the same, so u either have to multiply or divide a fraction. In this case, we'll multiply 4/5 with 10/10 so that the denominator will be the same as 5/50, and so that the value, 4/5(10/10), would still equal 4/5
4/5(10/10) + 5/50
40/50 + 5/50
45/50
simplify it
9/10

In the accompanying diagram, transversal EF intersects parallel lines AB and CD at G and H, respectively. If m∠EGB = 2x + 40 and m∠FHC = 3x - 10, what is the value of x
No diagram is provided but we can still work it out (it may vary).
So the from the description, we can tell that m∠EGB = m∠FHC through alternate exterior angles.
So,
m∠EGB = 2x + 40
m∠FHC = 3x - 10
m∠EGB = m∠FHC
2x + 40 = 3x - 10
40 = 3x - 2x - 10
40 = x - 10
40 + 10 = x
50 = x
x = 50
The value of x is 50

What is area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Area of square = a²
Area of rectangle = a × b
Area of circle = πr²
Given that,
The dimensions of the room are 200 feet by 180 feet
Each bottle of carpet shampoo can be used to shampoo 320 square feet of carpet
bottles of shampoo = ?
Total area we need to clean = 200 × 180
= 36000
one bottle can clean area = 320 square feet
number of bottles = Total area /one bottle can clean
number of bottles = 36000/320
= 112.5
≈ 113 bottles
So, The number of bottles required is 113

Abigail wants to ride her bicycle 30.4 miles this week. She has already ridden 7 miles.
If she rides for 3 more days, write and solve an equation which can be used to
determine m, the average number of miles she would have to ride each day to meet
her goal.
Answer:
3m + 7 = 30.4
m = 7.8
Step-by-step explanation:
3m, where m is the average number of miles per day, will represent how many miles she rides in the next 3 days.
She has already ridden 7 miles, so 7 has to be added to 3m in the equation.
Then, the equation has to be set equal to 30.4, because that is her goal for the week
Put this all together:
3m + 7 = 30.4
Solve for m:
3m + 7 = 30.4
3m = 23.4
m = 7.8
So, Abigail has to ride an average of 7.8 miles per day to meet her goal.

Answer:
32
Step-by-step explanation:
You use angle chasing. Since a triangle's angle has to add up to 180, the other angle is 180-79-69. This gives 32. So angle E is 32 degrees. Since they are parallel, that means that E equals to D. That means that D is 32, so 32 is now the answer.

Part A: A graph passes through the points (0, 2), (1, 3), and (2, 4). Does this graph represent a linear function or a non-linear function? Explain your answer in words
Part B: Write one example of a linear function and one example of a non-linear function.. (Use x and y as the variables) (10 points)
Answer:
Part A:
The graph passes through (0,2) (1,3) (2,4).
If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points. Using (0,2) and (1,3). Write in slope-intercept form, y=mx+b. y=x+2
Using (0,2) and (2,4). Write in slope-intercept form, y=mx+b. y=x+2. They are the same and in graph form, it gives us a straight line.
Since the slope is constant (the same) everywhere, the function is linear.
Part B:
A linear function is of the form y=mx+b where m is the slope and b is the y-intercept.
An example is y=2x-3
A linear function can also be of the form ax+by=c where a, b and c are constants. An example is 2x + 4y= 3
A non-linear function contains at least one of the following,
*Product of x and y
*Trigonometric function
*Exponential functions
*Logarithmic functions
*A degree which is not equal to 1 or 0.
An example is...xy= 1 or y= sqrt. x
An example of a linear function is 1/3x = y - 3
An example of a non-linear function is y= 2/3x

Answer:
1. 13.65, 136.5, 1365
2. 57.14, 5.714, .5714
Step-by-step explanation:
Answer:
Step-by-step explanation:
1.
1.365 x 10^1 = 13.65
1.365 x 10^2 = 136.5
1.365 x 10^3 = 1365
2.
571.4 / 10^1 = 57.14
571.4 / 10^2 = 5.714
571.4 / 10^3 = 0.5714
3.
479 x 10^(-1) = 4.79 * 10^1 = 47.9
479 x 10^(-2) = 4.79 * 10^0 = 4.79
479 x 10^(-3) = 4.79 * 10^(-1) = 0.479
4.
89.15 x 10^3 = 8.95 * 10^4 = 89500
5.
217.5 / 10^2 = 2.175
6.
I can't see if that is a comma or period, so I will do both
4,000 x 10^(-3) = 4 * 10^(0) = 4
4.000 x 10^(-3) = 4 * 10^(-3) = 0.004
7.
89.25 / 10^1 = 8.925
8.
3.107 x 10^1 = 31.07
9.
45.2 / 10^3 = 0.0452
10.
2,100 x 10^(-2) = 2.1 * 10^1 = 21
11.
5.7 / 10^3 = 0.0057
12.
I can't see if that is a 2 or 3, so I will do both. Standard form refers to the usual way that numbers are written. Power to the 3 means move the decimal right 3 places, while power to the 2 means move the decimal right 2 places.

Step-by-step explanation:
Compute the coefficient of determination. Round your answer to four decimal places. A regression equation is obtained for a set of data points. It is found that the total sum of square is 103.5, the regression sum of squares is 89.8, and the error sum of squares is 13.7.
a. 0.1324
b. 0.1526
c. 0.8676
d. 1.1526
Answer:
0.8676
Step-by-step explanation:
Given that :
Total Sum of Square (SST) = 103.5
Regression Sum of Square (SSR) = 89.8
Erroe Sum of Square (SSE) = 13.7
The Coefficient of determination (R²) :
R² = SSR / SST
R² = 89.8 / 103.5
R² = 0.8676328
R² = 0.8676
Select the two equations that will help you to solve this problem:
The combined average weight of an okapi and a llama is 450 kilograms.
3 llamas, on average, weigh 190 kilograms more than an average okapi.
You want to find the average weight of each type of animal.
Answer:
An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.
Step-by-step explanation:
Let,
x be the average weight of a Ilamas
y be the average weight of an okapi
According to given statement;
x + y = 450 Eqn 1
3x = y + 190 Eqn 2
From Eqn 2
y = 3x - 190 Eqn 3
Putting this value of y in Eqn 1
x + (3x-190) = 450
x + 3x - 190 = 450
4x = 450 + 190
4x = 640
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{640}{4}\\x=160\\[/tex]
Putting x = 160 in Eqn 3
y = 3(160) - 190
y = 480 - 190
y = 290
Hence,
An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.
In an interval whose length is z seconds, a body moves (32z + 2z^ 2 ) ft. What is the average speed v of the body in this interval?
This question is incomplete, the complete question is;
In an interval whose length is z seconds, a body moves (32z + 2z²) ft.
What is the average speed v of the body in this interval?
Answer: the average speed v of the body in this interval is 32 + 2z ft/s
Step-by-step explanation:
Given that;
Length of travel = z seconds
also the body moves (32z + 2z²) ft
i.e
distance travelled = (32z + 2z²) ft
average speed v of the body in this interval = ?
Now to get the Average Speed
we simply say;
Average Speed V = (32z + 2z²) / z
Average Speed V = 32 + 2z ft/s
Therefore the average speed v of the body in this interval is 32 + 2z ft/s
