Which transformation will always map a parallelogram onto itself?
OA
a 90° rotation about its center
B.
a reflection across one of its diagonals
Ос.
a 180° rotation about its center
OD.
a reflection across a line jolning the midpoints of opposite sides

Answers

Answer 1
Answer:  C) a 180 degree rotation about its center

Explanation:

Draw out a rectangle and make sure it's not a square. So you could have it be longer than it is tall. Imagine rotating that rectangle 180 degrees. The before and after (preimage and image) will be identical. The same applies if we slanted the sides of this rectangle. This shows that any parallelogram has rotational symmetry.

Side note: any rectangle is a parallelogram, but not the other way around.

Handy is making floor plan for a treehouse using a scale of 1 inch to 2 foot he wants to make the floor of the treehouse have a length of 8 foot how many inches should he show

Answers

Answer: [tex]4\ in.[/tex]

Step-by-step explanation:

Given

Handy uses a scale of 1 inch to 2 foot i.e. 1 inch of drawing represents 2 foot

For 8 foot length of tree house he draw x inch(say)

[tex]\therefore \ \dfrac{1\ \text{inch}}{2\ \text{foot}}=\dfrac{x}{8}\\\\\Rightarrow x=8\times \dfrac{1}{2}\\\Rightarrow x=4\ in.[/tex]

Each day for two weeks, Howard recorded values for the following two
variables.

• s, the number of students ahead of him in the lunch line when he got in
line
• m, the number of minutes elapsed between when he got in line and when
he sat down to eat
He then plotted his data on a scatter plot, with the horizontal axis representing
s and the vertical axis representing m, and drew a line of best fit. The equation
of the line was m = S + 1.
According to the equation of the line, if there are 52 students ahead of Howard
when he gets in the lunch line, how many minutes should he expect it to take
before he sits down to eat?

Answers

Given statement solution is :-  If there are 52 students ahead of Howard when he gets in the lunch line, he should expect it to take approximately 53 minutes before he sits down to eat.

According to the equation of the line given as "m = S + 1," where m represents the number of minutes elapsed and s represents the number of students ahead of Howard in the lunch line, we can substitute the value of s as 52 to find the expected number of minutes.

m = S + 1

m = 52 + 1

m = 53

Therefore, if there are 52 students ahead of Howard when he gets in the lunch line, he should expect it to take approximately 53 minutes before he sits down to eat.

a) Calculate the total amount of vinyl required for the spa (on both the interior and exterior)"

Answers

Step-by-step explanation:

the area of :

1) inside surface = (3.14× 1.25²)+(3.14×2.5×1.5)

= 4.90625 + 11.775 = 16.68125 m²

2) upper side surface= (3.14 × (1.35²-1.25²))

= 3.14× (1.8225-1.5625)= 3.14×0.26=0.8164m²

3) lateral surface= 3.14×2.7×1.6=13.5648m²

the total amount of vinyl required for the spa =

The width of a box is x units.

The height of a box is 3 units.

The length of a box is (x + 10) units.

Which expression represents the volume of the box, in cubic units, when x > 0?

Answers

Answer:

3x² + 30x

Step-by-step explanation:

width of a box = x units.

height of a box = 3 units.

length of a box = (x + 10) units.

Volume of the box = length × width × height

= (x + 10) * x * 3

= (x + 10) * 3x

= 3x² + 30x

Volume of the box = 3x² + 30x

n(AnB) = 9

Step-by-step explanation:

Step-by-step explanation:

n(A)=12

n(B)=7

n(AUB)=10

n(AnB)=?

let,n(AnB) be x

We know that,

or, n(AUB) = n(A)+n(B)-n(AUB)

How do you find theoretical probability?

Answers

Step-by-step explanation:

Theoretical Probability Definition

Theoretical probability is the theory behind probability. To find the probability of an event using theoretical probability, it is not required to conduct an experiment. Instead of that, we should know about the situation to find the probability of an event occurring. The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.

Find the probability of rolling a 5 on a fair die

Solution:

To find the probability of getting 5 while rolling a die, an experiment is not needed. We know that there are 6 possible outcomes when rolling a die. They are 1, 2, 3, 4, 5, 6.Therefore, the probability is,Probability of Event P(E) = No. of. Favourable outcomes/ No. of. Possible outcomes.P(E) = 1/6.Hence, the probability of getting 5 while rolling a fair die is 1/6.

Ryan conducted a 6-day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of information:

the amount of plant food remaining in the container after each day’s feeding
the height of the plant over time

Ryan found that the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by the end of his study.Which statement is true about the relationship between the amount of plant food remaining and the number of days?
A:This relationship is a function because more than one amount of plant food remains each day.
B:This relationship is not a function because more than one amount of plant food remains each day.
C:This relationship is not a function because only one amount of plant food remains each day.
D:This relationship is a function because only one amount of plant food remains each day.

Answers

Answer:

B: This relationship is not a function because more than one amount of plant food remains each day

Step-by-step explanation:

It is given that Ryan did an experiment by observing the effects of plant food and the growth of the sprouting bean plant. He made a note of the height of the bean plant and the amount of food remaining in the container for the plant after feeding each day.

Thus he observed that the plant food in the container decreases by an equal amount everyday as the bean plant grew. Thus this states that it is not a  function between the two as there are more than one plant food remaining each day for the plant.

A relationship is a function when one element belongs to one thing.

Theodore needs to mix a 10% saline solution with a 60% saline solution to create 200 milliliters of a 12.5% solution. How many milliliters of each solution must Theodore use

Answers

Answer:

x = 10% saline solution = 190 mililiters

y = 60% saline solution = 10 mililiters

Step-by-step explanation:

Theodore needs to mix a 10% saline solution with a 60% saline solution to create 200 milliliters of a 12.5% solution. How many milliliters of each solution must Theodore use

Let

x = 10% saline solution

y = 60% saline solution

x + y = 200

x = 200 - y

10% × x + 60% × y = 200 × 12.5 %

Hence:.0.1x + 0.6y = 25

Substituting 200 - y for x

0.1(200 - y) + 0.6y = 25

20 - 0.1y + 0.6y = 25

- 0.1y + 0.6y = 25 - 20

0.5y = 5

y = 5/0.5

y = 10 milliliters

Solving for x

x = 200 - y

x = 200 - 10

x = 190 mililiters
