A turtle travels mile in hour. At this rate, how far can the turtle travel in an hour
1/18 mile
2/9 mile
4 1/5 miles
4 1/2 miles
Answer:
4 1/2
Step-by-step explanation:
The origional question is ¨A turtle travels 1/2 mile in 1/9 hour. At this rate, how far can the turtle travel in an hour¨ To be honest i have no clue how to explain it but that is the awanser.
The turtle will travel [tex]4\frac{1}{2}[/tex] in an hour.
What is proportion?A proportion is an equation in which two ratios are set equal to each other.
Given that, a turtle travels 1/2 mile in 1/9 hour. we need to find, at this rate, how far can the turtle travel in an hour.
We will solve this by using proportionality, since, rate is constant,
Let the turtle travels x miles in an hour,
Therefore,
x / 1 = (1/2) / (1/9)
x = 1/2 × 9
x = 9/2
x = [tex]4\frac{1}{2}[/tex]
Hence, the turtle will travel [tex]4\frac{1}{2}[/tex] in an hour.

A store sells boxes of crayons. The boxes come in two sizes. A small box holds 12 crayons. A large box holds 38 crayons. In one day, the store sold 18 small boxes and 32 large boxes of crayons.
Which answer is the most reasonable estimate of the total number of crayons the store sold that day?
500 crayons because 10 × 30 + 20 × 10 = 500
1,000 crayons because 10 × 10 + 30 × 30 = 1,000
1,100 crayons because 40 × 20 + 10 × 30 = 1,100
1,400 crayons because 10 × 20 + 40 × 30 = 1,400
Answer:

Suzanne can put up 20 feet of fencing in 64 minutes. How many minutes will it take her to put up 35 feet of fencing?
Answer:
112 minutes
Step-by-step explanation:
Suzanne can put up 20 feet of fencing in 64 minutes.
We need to find minutes it will take to put up 35 feet of fencing.
20 feet = 64 minutes
1 feet = (64/20) minutes
For 35 feet,
[tex]35\ feet=\dfrac{64}{20}\times 35\\\\=112\ minutes[/tex]
So, it will take 112 minutes to put up 35 feet of fencing.

Zach wants to buy a skateboard that costs $85. He currently has $15 saved. Zach plans to save d, dollars to have enough to buy the skateboard. Which equation represents the amount of money Zach still needs to buy the skateboard? *
Answer:
85 = 15 + d
d = 70
Step-by-step explanation:
Cost of a skateboard = $85
Zach savings = $15
Amount needed more to save = $d
Which equation represents the amount of money Zach still needs to buy the skateboard?
Total cost = available savings + more savings
85 = 15 + d
85 - 15 = d
70 = d
d = 70

Baba Yaga lost her broom somewhere between her hut and Bald Mountain, and wants to get it back. She calculates that with a tailwind of 2 km/h, she can fly from her hut to Bald Mountain in 6 hours. Baba Yaga starts her trip, finds her broom 40 km before Bald Mountain, and turns around and flies home. The entire journey takes 9 hours. Find the speed Baba Yaga flies in quiet weather (with no tailwind or headwind).
Answer:
The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind) is approximately 2.9 km/h
Step-by-step explanation:
In the question, we have;
The speed of the tailwind = 2 km/h
The time it takes Baba Yaga to the Bald Mountain = 6 hours
The location where Baba Yaga finds her broom = 40 km before Bald Mountain
The duration of the entire journey = 9 hours
Let 'v' represent the speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), we get;
(v + 2) × t = (v - 2) × (t - 9)
v·t + 2·t = v·t - 9·v - 2·t + 18
2·t = 18 - 9·v - 2·t
4·t = 18 - 9·v
t = 4.5 - 2.25·v
(v + 2) × 6 = (v - 2) × (t - 9) + 40
6·v + 12 = (v - 2) × (4.5 - 2.25·v - 9) + 40
6·v + 12 = (v - 2) × (-2.25·v - 4.5) + 40
With a graphing calculator, we have;
6·v + 12 + 2.5·v² - 0.5·v - 9 - 40 = 0
5·v² + 11·v - 74 = 0
Using the quadratic formula
v = (-11 ± √(11² - 4·5×(-74)))/(2·5)
v ≈ 2.9, or v ≈ -5.1
Therefore;
The speed with which Baba Yaga flies in quiet weather (with no tailwind or headwind), v ≈ 2.9 km/h

0 1.5
for the ball to get to the ground the h=0 no hight it is now in the base point.
substitute the value t=0 into the equation we get 64.
since we want to know the time in seconds then we should subtract 60 from 64 (64-60=4)
then my answer is 0-4.

Write an equation for each line. A graph. Line k. Line m. Line p. Line r.
Answer:
line k: y = x + 4
line m: y = -2x + 4
line p: y = -6
line r: x = 1
Step-by-step explanation:
The equation for each line considering the graph is line k: y = x + 4, line m: y = -2x + 4, line p: y = -6, line r: x = 1
What is a line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Calculate the slopes of the lines as shown below,
[tex]m = y_2 - y_1 / x_2 - x_1[/tex]
For line k, m = 0 - (-4) / -4 -0
m = -1
Thus, the equation of a line having slope -1 and coordinates (0, 4) can be written as,
[tex]y-y_1 = m(x- x_1 )[/tex]
y - 4 = -1(x-0)
y -4 = -x
y = -x + 4
Similarly, write the equation for lines m, p, and r,
line m: y = -2x + 4
line p: y = -6
line r: x = 1
