This is not something we can really help you with, you'll have to do on your own paper. Just get a ruler and draw 8 different lines that measure 1-3 inches.

Question
I NEED HELP STAT PLZ PLZ PLZ Betty has between $40$ and $50$ pennies that she wants to arrange in a rectangular array. She notices she can arrange the pennies in three different ways without any gaps or spaces. However, if Betty adds two more pennies to her collection, she can only arrange the pennies in one way without any gaps or spaces: a straight line. How many pennies does Betty have?
Solution 1
If she adds two pennies, she can only arrange the pennies in a straight line.
A straight line is one penny wide. If she adds two pennies she ends up with a prime number of pennies.

Since she has between 40 and 50 pennies, she can have 41, 42, 43, 44, 45, 46, 47 ,48, or 49Â  pennies.

41 + 2 = 43 prime
42 + 2 = 44 not prime
43 + 2 = 45 not prime
44 + 2 = 46 not prime
45 + 2 = 47 prime
46 + 2 = 48 not prime
47 + 2 = 49 not prime
48 + 2 = 50 not prime
49 + 2 = 51 not prime

Only 43 and 47 are prime.
That means she has 41 or 45 pennies.
41 is prime, so it cannot be arranged in any other way than a straight line 1 by 41.
Let's look at 45.

45 = 3 * 3 * 5

45 = 9 * 5 = 3 * 15 = 45 * 1

She has 45 pennies.

Question
A cone with radius 2 feet and height 8 feet is shown.
Solution 1
The correct question is
What is the volume of a cone (in cubic feet) with a radius of 2 feet and a height of 8 feet?

we know that
volume of a cone=(1/3)*pi*r
Â˛*h
r=2 ft
h=8 ft
volume of a cone=(1/3)*pi*2Â˛*8-----> 33.49 ftÂł

33.49 ftÂł

Question
ANNA AND ALICE SHARE A RECTANGLE BEDROOM THAT IS 18 FEET LONG AND 14 FEET WIDE. THEY SPLIT THE ROOM INTO TWO HALVES BY PLACING A PIECE OF TAPE FROM THE NORTHWEST CORNWR OF THE ROOM TO THE SOUTHEAST CORNWR OF THE ROOM. WHT IS THE AREA OF EACH GIRLS HALF OF THE ROOM
Solution 1
First, you have to find the area of the WHOLE bedroom.
Equation: 18Â Ă 14 = 252.

The total area of the bedroom is 252^2 feet.

Finally, divide.

252Â Ăˇ 2 =Â  126.

The area of each of the sections is 126.

Please mark me as brainliest. I really need it.

Question
the original value of an investment is $1,800. if the value has increased by 7% each year, write an exponential to model the situation. then, find the value of the investment after 15 years Solution 1 For this case we have an equation of the form: Â y = A (b) ^ t Â Where, Â A: initial amount Â b: growth rate Â t: time Â Substituting values we have: Â y = 1800 * (1.07) ^ t Â For 15 years we have: Â y = 1800 * (1.07) ^ 15 Â y = 4966.256773$
Â
An exponential to model of the situation is:
Â
y = 1800 * (1.07) ^ t
Â
the value of the investment after 15 years is:
Â
y = 4966.256773 \$
Question
Solve the equation <(a-5)-5=3
Solution 1
The first step for solving the equation (a - 5) - 5 = 3 is to remove the parenthesis.
a - 5 - 5 = 3
Calculate the difference between -5 and 5.
a - 10 = 3
Now move the constant to the right side of the equation and change its sign.
a = 3 + 10
a = 13

Question
Centennial park is evaluating the capacity of the park and have determined that 15 people can comfortably stand in a section that is 5ft by 8ft , the park has dimensions that are 400yds by 200 yds estimate the number of people who can fit in the park
Solution 1

We have been given that 15 people can comfortably stand in a section that is 5ft by 8ft .

Hence, the area of this section is given by

Hence, we can say that 15 people can comfortably stand in an area 40 square feet.

Now, we know that 1 yard is equal to 3 feet.

Hence, the area of the section 400yds by 200 yds is equal to

Now, in 40ft^2, 15 people can stand comfortably.

Hence, in 720000 ft^2, number of people can stand comfortably is

Therefore, 270000 people can stand in the park of dimension 400 yds by 200 yds

Solution 2
If you multiply all those numbers you will get 5.76e9 yds
Question
Which expression is not equivalent to the following expression? 15 - 3 + 15 - 3 - 3 + 15 A. 3(15 - 3) B. 3(15) C. 3(15 + 3) D. 3(12)
Solution 1
In the above problem:Â  it appears that the original expression is equal to 36.

A. 3(15-3) = 3(12)=36
B. 3(15) = 45
C. 3(15+3) = 3(18)=54
D. 3(12) = 36

So it looks like choices A and D are equivalent to the original expression.

Question
Anna and Alice share a rectangle bedroom that is 18 feet long and 14 feet wide. they split the room into two halves by placing a piece of tape from the northwest corner of the room to the southeast corner of the room. what is the area of each girls half of the room?
Solution 1
The area of the whole room = 14Â Ă 18 = 252

Since they divide it by half, divide the are by 2.

252Â Ăˇ 2 = 126

Hope this helpedâşâş
Solution 2
126 is the area of one hafe of the room
