Answer:
Lucy got 18 questions correct.
Step-by-step explanation:
To find the percentage of a number, you must multiply the number by 0. + the percent.
So, to solve this problem, we must do the following:
24 x 0.75 = 18
Therefore, Lucy got 18 questions correct.
Answer:

A river current carried a fallen tree branch 1 over 3 of a mile in 1 over 4 of an hour. At what speed is the water in the river flowing, in miles per hour?
In miles per hour, 4/3 speed represents the flow of water in the river, and its calculation can be defined as follows:
Speed calculation:Distance = [tex]\frac{1}{3}[/tex] miles
Time= [tex]\frac{1}{4}[/tex] hours
speed=?
Speed Definition:
An object's speed is indeed the pace at which it moves along a path in time, whereas its velocity is the rate and direction of travel.
The formula for calculating the speed:
[tex]\to[/tex] speed =[tex]\bold{\frac{Distance}{time}}[/tex]
[tex]=\frac{\frac{1}{3}}{\frac{1}{4}}\\\\={\frac{1}{3} \times \frac{4}{1}}\\\\={\frac{4}{3}}\\\\[/tex]
Therefore, the calculated speed of water flow is [tex]\frac{4}{3}[/tex] miles per hour.

Answer: For the first question, m = 1.5 and y-intercept = 5, so your equation for the first one should be, y = 1.5x + 5.
And for the second question, m = -1.75 and y-intercept = 4, so your equation for the second one should be, y = -1.75x + 4.
Step-by-step explanation: For the 1st one, subtract 3x to get -2y = -3x - 10, then divide by -2 to get y = 1.5x + 5.
For the 2nd one, subtract 7x to get 4y = -7x + 16, then divide by 4 to get y = -1.75x + 4.
Hope this helps you! :)
DUE SOON PLS HELP: All of the points on the picture are on the same line. 1. Find the slope of the line. Explain your reasoning.
(if possible can you link a video to help I don't understand this at all)
Answer:
Look below :)
Step-by-step explanation:
1. To find the slope of a line, we can use this expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
In order to use that expression, we need to use two points. The graph given only provides you with two complete points, so we'll use those.
(4, 4) = (x1, y1) (12, 20) = (x2, y2)
Now we can input the values into the expression:
[tex]\frac{y2 - y1}{x2 - x1}[/tex] = [tex]\frac{20 - 4}{12 - 4}[/tex]
Let's solve for the slope:
20 - 4 = 16
12 - 4 = 8
[tex]\frac{16}{8}[/tex]
To simplify 16/8 divide both the numerator and the denominator by 8:
16/8 = 2
8 = 1
You get 2/1 or just 2.
The slope of the line is 2.
2. To make an equation for the line, we'll use slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. We already know the value of the slope is 2, so now we need to find the y-intercept. We can find the y-intercept using a given point and the slope. In this example, I'll use the point (4, 4). Let's input the values into the equation:
y = mx + b
4 = 2(4) + b
Now let's solve for b:
4 = 8 + b
Subtract 8 from both sides to isolate the b:
4 - 8 = 8 - 8 + b
-4 = b
The y-intercept of the equation is -4.
Now that we know the values for the slope and y-intercept, we can write the equation:
y = 2x - 4
3. To find the values of a and b, we can use the equation we made in the previous question.
First we'll find a:
The point we are given is (a, 16). We know the y-value is 16, so we can put that into our equation. We can also replace x with a:
y = 2x - 4
16 = 2a - 4
Now we can solve for a:
First, add 4 to both sides to isolate the 2a:
16 + 4 = 2a - 4 + 4
20 = 2a
Then divide both sides by 2 to isolate a:
20/2 = 2a/2
10 = a
The value of a is 10.
Now let's find b:
This is similar to finding a. The point we are given is (8, b). We know the value of x is 8, and we can replace y with b in the equation:
y = 2x - 4
b = 2(8) - 4
Let's solve:
b = 2(8) - 4
b = 16 - 4
b = 12
The value of b is 12.
4. Finally, to find the y- coordinate when x=0, all we have to do is input 0 in for x in the equation and then solve for y:
y = 2x - 4
y = 2(0) - 4
y = 0 - 4
y = -4
When x = 0, y = -4.
The answer for what the y-coordinate is when x = 0 will always be the value of the y-intercept.
I hope this helps!

12/30
2/50
The ratio of males to total students in a mathematics class is 3 to 30. What percent of the class is male?
40%
10%
45%
12%
Answer: 12/30
and 40 percent
Step-by-step explanation:
Well it’s 12 to 30 so just put a fraction bar
and 12 divided by 30 is .4
Answer:
The answers are 12/30 and 10%
Step-by-step explanation:
It's 40% because the ratio of males to total students is 12 to 30, or 12:30, which is equal to 12/30.
The other answer is 10% because the ratio of males to total students is 3 to 30, or 3:30, which is equal to 1/10. Then you would do 100 divided by 10 which would give you 10 so it's 10%.
Hope this helps!

A watch cost $76.00. If the sales tax rate is 7% what is the amount of sales tax? What is the total cost?
Answer:
Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.

Aiden asked a group of students to choose their favorite type of music from the choices of rock, hip-hop, and country. The results of the survey are shown in the graph.
Based on the graph, how many students in a class of 360 students would be expected to choose hip-hop or rock as their favorite type of music?
Hiphop has 40
Rock has 20
Answer:
240
Step-by-step explanation:
20% of the students like rock and 40% like hip-hop. That means that 60% of the 360 students would be expected to choose one of the two. Because you don't know the other 10%, you would assume that they would have the same ratio of students who like the country to those who like rock and hip-hop. 60 is 2/3 of 90, so you would expect 2/3 of the students to like hip-hop or rock. 2/3 of 360 is 240.

Write an equation for the following graph. Keep your slope as a fraction.
Answer:
y= 10/3x + 20
Step-by-step explanation:
the slope is 10/3 because from one point to another (on the line) it moves up 10 (from 20 to 30) and to the right 3 (from 0 to 3)
the y intercept is 20 because when x = 0, y = 20 which we can see on the graph
