Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.
Quadrilateral A B C D is translated down and to the left to form quadrilateral O L M N.
If AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units, what is LO?
5 units
6 units
8 units
10 units
Answer:
LO = 6 units ⇒ B
Step-by-step explanation:
Translation does not change the size or the shape of the figure
∵ Quadrilateral ABCD is translated down and left to form
quadrilateral OLMN
∴ The image of side AB is side OL
∴ The image of side BC is side LM
∴ The image of side CD is side MN
∴ The image of side AD is side ON
∵ AB = 6 units
∵ Translation does not change the size of the figure
∴ The image of AB = 6 units
∵ The image of AB is OL
∴ The length of OL = 6 units
∵ OL = LO
∴ LO = 6 units
The length of LO of the newly translated quadrilateral is; Option B: LO = 6 units.
Translation of objects in mathematics simply means to move an object from one point to another without a change of length or figure.
Now we are told that Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.
Thus means Quadrilateral OLMN is still same size and length as ABCD and as such the sides will correspond in order.
Thus, it means that;
AB = OL
BC = LM
CD = MN
AD = ON
We are given;AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units
Thus, since AB = OL, we can say that;
LO = 6 units.

b) 12%
Step-by-step explanation:
you need to use the equation given
y = -6.83x + 108
x is the rank
y is the probability of winning 1st game
a) for rank 8th or x=8
y = -6.83(8) + 108 = 53.36 or 53%
b) for rank 14th or x=14
y = -6.83(14) + 108 = 12.38 or 12%

1. Suppose Leif can rake his entire yard in 2.5 hours, while his younger sister, Autumn, can do it in 4 hours by herself. How many minutes will it take the two of the to rake the entire yard if they are working together, to the nearest whole number? Please answer in a number of minutes.
2. Once Leif and Autumn have all of the leaves in their yard in a huge pile, they decide to do a little math with their pile of leaves. They notice that all of the leaves are yellow and/or red. So, they decide that Leif will count the leaves with any red (5550 leaves) and Autumn will count the leaves with any yellow (6820 leaves). Then, they get their other little brother, Oakie, to come out and count the leaves that have both yellow and red on them (4370 leaves). Using their reported numbers, how many leaves are in the pile? Please just provide the number of leaves.
3. Leif bets Autumn that she can't reach into the middle of the pile and pull out three leaves with yellow on them in her first three picks, without replacement. Assuming the different kinds of leaves were all mixed up together again and randomly distributed throughout the pile, what is the probability that she will be successful? Express your answer as a decimal to the nearest hundredth.

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!

Jordan signed up for the Annual Cross Florida bike ride which is a 170 mile bike ride. After weeks of training he rides at an average of 15 miles per hour. What is x in real world context?
Answer: 11.3 hours
Step-by-step explanation:
Before this question is another asking for an equation depicting this with Jordan's progress in miles (y) after a number of hours (x).
That would be y = 15x
x in the real world context would be the number of hours it would take for Jordan to finish the 170 mile bike race.
To solve this make y to be 170 and solve for x.
170 = 15x
x = 170/15
x = 11.3 hours

Write the component form of the vector that translates P(4,5) to P'(-3,7)
Answer:
The component form of the vector is v = -7·i + 2·j
Step-by-step explanation:
The given parameters are;
The coordinates of the initial point = P(4, 5)
The coordinates of the point after the translation by the vector, v = P'(-3, 7)
Therefore, we have;
The horizontal component of the vector, vₓ = (-3) - 4 = -7
The vertical component of the vector, [tex]v_y[/tex] = 7 - 5 = 2
The magnitude of the translation, v = √([tex]v_y[/tex]² + vₓ²) = √((-7)² + 2²) = √53 ≈ 7.28
Therefore, the component form of the vector, v, is given as follows;
v = vₓ·i + [tex]v_y[/tex]·j
Substituting the known values of vₓ and [tex]v_y[/tex] gives;
v = -7·i + 2·j
The component form of the vector is v = -7·i + 2·j.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given table is
x 0 2 3 4
y -2 0 1 2
The slope is m=2-4/1-3=-2/-2=1
m=1
y intercept is 2=4+b
b=-2
Hence, y=x-2 is the function represents the relationship between x and y.

The graph shows a proportional relationship between the number of miles and the number of hours Marco bikes.
What equation relates the distance, y, and the time, x? Enter your answer in the box

Answer:

Step-by-step explanation:
Its pretty simple
The equation that relates the distance (y) and the time (x) is → y = 15x.
What is the general equation of a Straight line?The general equation of a straight line is -
y = mx + c
where -
m is slope of line
c is the y - intercept
Given is a graph that shows a proportional relationship between the number of miles and the number of hours Marco bikes.
First we will find the slope of the straight line. Take two set of coordinates from the graph. We will take → (1, 15) and (2, 30).
The slope of the line can be calculated using the formula -
m = (y₂ - y₁)/(x₂ - x₁)
m =(30 - 15)(2 - 1)
m = 15
The line passes through the origin so its y - intercept (c) will be zero. So, we can write the equation as → y = 15x.
Therefore, the equation that relates the distance (y) and the time (x) is → y = 15x.

Use a proportion to find the missing side length in the following similar figures. Please help me understand and figure out how to solve this question. Thank You! :)
Answer:
x = 4.5 m ⇒ A
Step-by-step explanation:
The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal
In the given figure
∵ The two triangles are similar
∵ 2 m and x are corresponding sides
∵ 4 m and 9 m are corresponding sides
∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]
→ By using cross multiplication
∴ x × 4 = 2 × 9
∴ 4x = 18
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]
∴ x = 4.5 m

Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8 a car, to raise more money. Tony solved the inequality 8x + 200 Greater-than-or-equal-to 500, and determined that if they wash 37 cars, they will have enough money. Is he correct? Explain.
Answer:
No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5. Since the class must wash a whole number of cars, they need to wash at least 38 cars.
