Jared drew this rectangle. Then, he drew another rectangle that was twice as long but had the same width. In what way do the area and perimeter of Jared’s new rectangle change from the area and perimeter of the original rectangle?
Answer:
Step-by-step explanation:
one rectangle has the area, A₁=LxW and,
perimeter P₁=2L+2W
the second rectangle has the area A₂=2L x W,
and perimeter P₂=2(2L)x2W= 4Lx2W
the second area doubles compared to the first area
the perimeter gets increased with double the length

Three regular hexagons are put together to make a larger shape. The perimeter of one of the regular hexagons is 18cm. Find the perimeter of the larger shape.
Answer:
steps below
Step-by-step explanation:
2 kinds of larger shapes can be make
kind 1: 18 x 4 x 3 = 216 cm
kind 2: 18 x (5+5+4) = 252 cm
The perimeter of the larger shape formed by putting three regular hexagons together is 216 cm.
When three regular hexagons are put together to form a larger shape, they form a regular hexagon with an equilateral triangle at each end.
The perimeter of the larger shape can be calculated as follows:
Perimeter of larger shape = Perimeter of hexagon + Perimeter of equilateral triangle
Since the hexagon has six sides of equal length, its perimeter is [tex]\(6 \times 18 \, \text{cm} = 108 \, \text{cm}\)[/tex].
Each equilateral triangle has three sides of equal length, and each side of the equilateral triangle is equal to one side of the hexagon.
So, the perimeter of each equilateral triangle is [tex]\(3 \times 18 \, \text{cm} = 54 \, \text{cm}\)[/tex].
Since there are two equilateral triangles, the total perimeter contributed by the equilateral triangles is [tex]\(2 \times 54 \, \text{cm} = 108 \, \text{cm}\)[/tex].
Finally, to find the perimeter of the larger shape, add the perimeters of the hexagon and the two equilateral triangles:
Perimeter of larger shape = 108 cm + 108 cm = 216 cm
Thus, the perimeter of the larger shape is [tex]\(216 \, \text{cm}\)[/tex].

Solve the following problem for the roots by using the quadratic formula.
2(6 - x) = x(x + 5)
Answer:
The roots are [tex]x=\dfrac{-7+ \sqrt{97}}{2}\text{ and }x=\dfrac{-7- \sqrt{97}}{2}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]2(6 - x) = x(x + 5)[/tex]
Remove the parenthesis and simplify.
[tex]12-2 x= x^2 + 5x[/tex]
[tex]x^2+7x-12=0[/tex]
Now use the quadratic formula [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex].
Susbtitute a=1, b=7 and c=-12 in above formula.
[tex]x=\dfrac{-7\pm \sqrt{7^2-4(1)(-12)}}{2(1)}[/tex]

Police chases a driver. The police is 1 mile behind the driver. The speed of the police is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?
Answer:
0.20 hour
Step-by-step explanation:
According to the problem, computation of the given data are as follows,
Speed of police = 90 mph
Speed of chased car = 85 mph
Distance to be chased = 1 mile
So, we can calculate the time to catch by using following formula:
Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)
= 1 ÷ ( 90 - 85)
= 1 ÷ 5
= 0.20 hour
Cindy decided to shop online. She was buying books ($6 each) and candles ($4 each). She bought 15 items and spent $78. How many books did she buy?
Answer:
9 books
Step-by-step explanation:
78=b(6)+c(4)
78=9(6)+6(4)
78=54+24
78=78-True
As per linear equation, Cindy bought 9 books online.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Given, Cindy was buying books ($6 each) and candles ($4 each).
She bought 15 items and spent $78.
Let, she bought 'x' books.
Therefore, she bought (15 - x) candles.
Now, the cost of the total 15 items is
= $[6x + 4(15 - x)]
= $[6x + 60 - 4x]
= $[2x + 60]
Therefore, 2x + 60 = 78
⇒ 2x = 78 - 60
⇒ 2x = 18
⇒ x = 9
Therefore, Cindy bought 9 books.

A model car has a scale factor of 1/64. The diameter of a tire on the model is 0.43 inches. So, the diameter of the tire on an actual car must be inches. Your answer must be correct to one decimal place.
Answer:27.52 inches
Step-by-step explanation:
Given
Scale factor [tex]\frac{1}{64}[/tex] i.e.
[tex]\dfrac{\text{Model}}{\text{Prototype}}[/tex]
The diameter of the model tire is 0.43 inches
Scale factor = [tex]\dfrac{\text{dia. of model}}{\text{dia. of actual car}}[/tex]
[tex]\frac{1}{64}=\frac{0.43}{D}\\D=64\times 0.43=27.52\ \text{inches}[/tex]

2. 25- t = 15; 9, 10, 11
I need answers for both please I’ll give 50 points!!
Answer:
1.) The answer is b = 6
2.) The answer is t = 10
Step-by-step explanation:
For the first equation in order to fin out the answer we do.....
b + 8 = 14
b + 8 - 8 = 14 - 8
b = 6
For the second question we do....
25 - t = 15
25 - t + t = 15 + t
25 = 15 + t
25 - 15 = 15 + t -15
10 = t
Here is a linear equation: y = 10+ 1. Are (1,1.5) and (12, 4) solutions to the equation? Select the correct choice.
Answer:
[see below]
Step-by-step explanation:
Assuming that the equation is y = 10x + 1
(12, 4)
4 = 10(12) + 1
4 = 120 + 1
4 ≠ 121
(12, 4) is not a solution.
(1, 1.5)
1.5 = 10(1) + 1
1.5 = 10 + 1
1.5 ≠ 1
They are not solutions to the equation.

Rose would be saving 50 dollars after 10 months. So you know that Rose got $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.

Isaiah has $7.15 in Dimes and Nickels. He has a total of 91 coins. How many of each coin does he have? Group of answer choices dimes: 31 nickels 60 dimes: 60 nickels: 31 dimes: 52 nickels: 39 dimes: 39 nickels: 52
Answer:
Dimes = x = 52
Nickels = y = 39
Step-by-step explanation:
Let
Dimes = x
Nickels = y
x + y = 91 (1)
0.10x + 0.05y = 7.15 (2)
From (1)
x = 91 - y
Substitute x = 91 - y into (2)
0.10x + 0.05y = 7.15
0.10(91 - y) + 0.05y = 7.15
9.10 - 0.10y + 0.05y = 7.15
- 0.10y + 0.05y = 7.15 - 9.10
-0.05y = -1.95
y = -1.95 / 0.05
= 39
Substitute y = 39 into (1)
x + y = 91
x + 39 = 91
x = 91 - 39
x = 52
Dimes = x = 52
Nickels = y = 39

Three ballet dancers are positioned on stage. Jada is 2 meters straight behind Trisha and 4 meters directly left of Ken. When the music begins, Jada twirls to Ken's position, then leaps to Trisha's position, and finally walks back to her original position. How far did Jada travel? If necessary, round to the nearest tenth.
Answer:
10.5 meters
Step-by-step explanation:
in their starting position all three dancers form a right triangle with legs equal to 2m and 4m.
Jada to Ken = 4m
From Ken's position to Trisha's, Jada goes another 2[tex]\sqrt{5}[/tex]m*
From Trisha's position to her original position, Jada goes another 2m
