= 7 yd • 4 yd

= 28 yd^2

3 feet = 1 yard, so 9 ft^2 = 1 yd^2

28 yd^2 (9 ft^2/1 yd^2) = 252 ft^2

Kelly owns a comic book that is currently worth $840, and she believes that its value will increase by $30 every year. Kelly plans to sell the comic book for $1,500 and wants to know how long she must wait until the comic book's value reaches at least 90% of that amount.
This problem can be solved with an inequality that uses the variable x.
How should x be defined?
x = the number of years until the comic book is worth 90% of $1,500
x = the price Kelly plans to sell the comic book for
x = the current value of the comic book
x = the number of years Kelly has already owned the comic book

Maggie has a rectangular box with a length of 6 1/2 inches, a width of 9 inches and a height of 9 1/2 inches.

What is the volume of Maggies box ?\

Answers

6 1/2 x 9 x 9 1/2 = 555.75

Answer:

555 3/4 inches³

Step-by-step explanation:

*To find volume, you just multiply the three lengths together*

1. 6 1/2 x 9 = 58 1/2

2. 58 1/2 x 9 1/2 = 555 3/4

When you do volume, your answer must end in inches "cubed" which is the three that hangs in the air since cubed means to the third power.

In triangle JKL, < K Measures 50 and < J is congruent to

Answers

The angle measures of J and L are given as follows:

m < J = m < L = 65º.

How to obtain the angle measures?

To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles for this problem are given as follows:

<J.<K.<L.

Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:

50 + x + x = 180

2x = 130

x = 65º.

rohan cycled 30 km in 2 h.how long will he take to cycle 45 km if he continues at the same rate

Answers

Answer:

3 hours

Step-by-step explanation:

We can use ratios to solve

30 km         45 km

---------   = ---------------

2 hours        x hours

Using cross products

30 * x = 2 * 45

30x = 90

Divide each side by 30

30x/30 = 90/30

x = 3

Rohan cycled 30 km in 2 hours, so his speed is 30/2 = 15 km/h. If he continues at the same rate, he will take 45/15 = 3 hours to cycle 45 km.

Which of the following represents the constant of proportionality in the table below?

Answers

The constant of proportionality is the one in option B; k = 95

Which is the constant of proportionality?

Remember that a proportional relation can be written as:

y = k*x

Where k is the constant of proportionality.

Here we can define the variables:

x= months.

y= total revenue.

Now we can use any pair of values in the table to get the constant of proportionality. For example if we use the first pair we get:

x = 2

y = 190

Replacing these values we will get:

190 = k*2

190/2 = k

95 = k

That is the constant of proportionality, the correct option is B.

Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.

Answers

Answer:

Beth's class left for the field trip at 7:13 A.M..

Step-by-step explanation:

To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.

The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.

To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.

9:41 A.M. minus 55 minutes is 8:46 A.M..

8:46 A.M. minus 93 minutes is 7:13 A.M..

Therefore, Beth's class left for the field trip at 7:13 A.M..

(0.35 + 5.2) x. =27.75

Answers

To solve for x, we need to isolate it on one side of the equation.

First, we need to perform the addition inside the parentheses:

5.55 x = 27.75

Next, we can solve for x by dividing both sides of the equation by 5.55:

x = 5

Therefore, the value of x that makes the equation (0.35 + 5.2) x = 27.75 true is 5.

To solve this linear equation, we can re arrange the numbers.

Q) (0.35 + 5.2) x = 27.75

Ans. x (0.35 + 5.2) = 27.75

        0.35x + 5.2x = 27.75

        5.55x = 27.75

        x = 27.75/5.55 = 5

        x = 5

       

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times. Using the results of the simulation, what is the experimental probability that the player does not hit the dartboard? Express your answer as a decimal.

Can someone please help me i am so confused.

Answers

Answer:

0.25

Step-by-step explanation:

If the person made it 105 out of 140 times, that can be written as a fraction: 105/140

Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.

105 divided by 140 = 0.75

0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25

Hope this helps

The experimental probability that the player does not hit the dartboard is,

⇒ 1 / 14

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.

Hence, Number of not hit dartboard is,

⇒ 140 - 105

⇒ 35

Thus, The experimental probability that the player does not hit the dartboard is,

⇒ 35 / 140

⇒ 7 / 28

⇒ 1 / 14

Because it only takes two boxes going up until the arrow reach this the corner of of the boxes. And X is 1 because it only takes one box to the left to get to the corner.
