Answer:
Step-by-step explanation:
1)first lets figure what the rate at which they are traveling is. we know that the have traveled 1 and 3/4 miles in 2 and 1/3 minutes. lets now convert this to miles per 1 minute. we can find this by taking our distance traveled and dividing it by out time taken.
(1 and 3/4) / (2 and 1/3)= .75 or (3/4)
2) now we can take this number and multiply it by 33 minutes to get 24.75 miles
3) we can then multiply .75 by 60 minutes to get that the care has traveled 45 miles in 1 hour.

The first angle in a triangle the measure of the first angle is three times that of the second angle. The second angle is two times that of the third angle. Find the ratio of the angles in the triangle.
Answer
6;2;1
Step-by-step explanat
first angle is three times that of the second angle.
second angle is two times that of the third angle.
so first angle is 6 times that of the 3rd angle.
so 6;2;1

A bowl contains red and brown marbles. A scoop of marbles that is a representative sample contains 18 red marbles and 27 brown marbles.
a. Can you predict if there are more red marbles or more brown marbles in the bowl? Explain.
b. There are 850 marbles in a bowl. If you pick one marble from the bowl, are you more likely to pick a red marble or a brown marble?
a. Based on the information provided, it is not possible to predict if there are more red marbles or more brown marbles in the bowl, because the sample size is not given. It is possible that the sample is not representative of the overall population of marbles in the bowl, and thus the sample proportions may not accurately reflect the actual proportions of red and brown marbles in the bowl.
b. To determine the probability of picking a red or brown marble from the bowl, we need to know the overall proportion of red and brown marbles in the bowl. From the given sample, we know that the proportion of red marbles is 18/45 or 0.4, and the proportion of brown marbles is 27/45 or 0.6. Assuming that these proportions are representative of the overall population of marbles in the bowl, we can predict that we are more likely to pick a brown marble (with a probability of 0.6) than a red marble (with a probability of 0.4) if we pick one marble from the bowl.

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answer:
Step-by-step explanation:
To make the race close, the length of the race should be 450 meters.
Here's the reasoning behind the answer:
Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.
The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.
During this time, Henri would have walked a distance of 1 x 18 = 18 meters.
So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).
To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.
Let's call the total distance of the race "d."
So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).
We can set up an equation to solve for d:
d/1 = (d + 27)/2.5
Solving for d, we get:
d = 450
So, the race should be 450 meters long for Henri to win in a close race.

Answer:
152 grams of zinc
Step-by-step explanation:
You can always first create some ratios to clean it up
[tex] \frac{zinc}{copper} = \frac{4}{19} = \frac{x}{722} [/tex]
x being zinc, what we need to find
Next we can cross multiply
[tex]19x = (722)(4)[/tex]
[tex]19x = 2888[/tex]
Lastly, we will divide both sides by 19 to get X alone.
[tex]x = 152[/tex]
PLEASE HELP ME ASAP!! Charlie is practicing the long jump. His first jump is a distance of 16[tex]\frac{5}{6}[/tex] feet. His second jump is a distance of 18 [tex]\frac{2}{3}[/tex] feet. How much longer is Charlie's second jump? Please explain!!!
Answer:
[tex]2 \frac{1}{6} [/tex]
Step-by-step explanation:
So we have
[tex]16 \frac{5}{6} \: and \: 18 \frac{2}{3} [/tex]
If you have the same denominator for each fraction, you'd be able to subtract the numerators like regular subtraction
Seeing the 2/3, if we multiply each number by 2, you get
[tex]18 \frac{4}{6} [/tex]
Now you have 5/6 and 4/6. Since they both have 6 at the bottom, you can subtract 5 and 4.
5-4=1
Now you have 1/6.
Then you can just subtract the 18 and 16 like normal giving you 2.
After we combine our numbers, we get 2 1/6. Hope this helps

Answer:
Step-by-step explanation:
13oz bottle of dish soap sells for 2.34
Answer: hope this helps ♡
The unit price of the 13 oz bottle is $0.18 per oz
The unit price of the 30 oz bottle is $0.53 per oz
The 13 oz bottle for $2.34 is a better deal.
Step-by-step explanation:
Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol) :)
13 oz = $2.34
13 oz bottle is $? per oz
[tex]\frac{2.34}{13}[/tex] = 0.18
1 oz = $0.18
(double check: 0.18×13=2.34)
30 oz = $15.90
30 oz bottle is $? per oz
[tex]\frac{15.9}{30}[/tex] = 0.53
1 oz = $0.53
(double check: 0.53×30=15.9)
The 13 oz bottle for $2.34 is a better deal.

2. Anika is on the crew to set up rides for the state fair. The crew does most of the setup on the day that the fair arrives at the fairground and then continues to work on finishing the setup for about a week to have the rides ready to go in time for the opening of the fair. The scatter plot shows Anika's setup time on different days and the linear model for the data.
Annika’s Setup Time
Time (Days)
(a) What is the equation of the line, written in slope-intercept form? Show how you determined the equation. ( also find the slope and equation in point slope form)
(b) Anika arrived on Day 0. Based on the linear model you created in Part A, predict how long Anika worked on Day 0.
(c) Approximately how much did her setup time decrease per day?
Answer:
(a) The equation of the line, written in slope-intercept form, is y = -5x + 20. This can also be written in point slope form as y - 20 = -5 (x - 0). The slope is -5 and this was determined by looking at the trendline on the scatter plot.
(b) Based on the linear model created in Part A, Anika worked for 20 hours on Day 0.
(c) Anika's setup time decreased by approximately 5 hours per day based on the linear model.
Answer:
Step-by-step explanation:
(a) The equation of the line, written in slope-intercept form, is y = -5x + 20. This can also be written in point slope form as y - 20 = -5 (x - 0). The slope is -5 and this was determined by looking at the trendline on the scatter plot.
(b) Based on the linear model created in Part A, Anika worked for 20 hours on Day 0.

The necklace charm shown has two parts, each shaped like a trapezoid with identical dimensions.
What is the total area, in square millimeters, of the charm?
Enter your answer in the box.
Answer:
855mm
Step-by-step explanation:
A = (b₁ + b₂)h / 2
A = (25mm + 32mm)(15 mm) / 2
A = 427.5 mm²
total area = (427.5 mm²)(2)
total area = 855 mm²
Answer:855mm

You have a bag of marbles with 630 marbles in it: 110 red, 230 green, and 290 blue. You pull out 1 marble, record the color, and replace it.
After you do this 100 times, the table shows the number of times each color was drawn:
Red Green Blue Total
21 35 44 100
Give exact, reduced answers.
a) What is the theoretical probability of drawing a blue?
b) What is the experimental probability of drawing a blue?
Answer:
a) The theoretical probability of drawing a blue marble is the ratio of the number of blue marbles to the total number of marbles in the bag, which is:
P(blue) = number of blue marbles / total number of marbles
= 290 / 630
= 29 / 63
So the theoretical probability of drawing a blue marble is 29/63.
b) The experimental probability of drawing a blue marble is the ratio of the number of times a blue marble was actually drawn to the total number of trials, which is:
P(experimental blue) = number of times a blue marble was drawn / total number of trials
= 44 / 100
= 11 / 25
So the experimental probability of drawing a blue marble is 11/25.

Write the equations of each line in slope-intercept form. (y=mx+b)
Answer:
The equation would be y = -2x + 19
Step-by-step explanation:
To find this, we can use the point and the slope in point-slope form. The we solve for y.
y - y1 = m(x - x1)
y - 7 = -2(x - 6)
y - 7 = -2x + 12
y = -2x + 19
