John sells candy bars for 2$ each. How much will he make if he sells 10 bars
Each Candy Bar is $2, so if he sells 10, you just need to multiply,
10 * $2 = 20
So He'll make $20, selling 10 bars.
If he sells 50 bars then just multiply,
50 * $2 = 100
So He'll make $100 selling 50 bars.
Answer:
he will make $20 dallors
10×$2=20
Rachel runs 4 miles in 23 minutes. How many miles does she run per minute?
Answer:
To calculate how many total miles Rachel runs per minute, setting up a unit rate, that is a rate with a denominator of 1, would be helpful.
Step-by-step explanation:
Use the current problem to determine a rate.
23 minutes/4 miles
Now, set up a unit rate.
1 minute/x miles = 23 minutes/4 miles
To solve for x, we can use simple division strategies. We divide 23 by 23 to receive 1 minute. Likewise, dividing the current milage by 23 would wield the correct unit rate. To do this, divide 4 by 23.
4/23 = 0.1739130434782609
Finally, simplify your answer to receive 0.17.
Therefore, Rachel runs ~0.17 miles per minute. (Note that this answer is only a rounded answer of her actual milage per minute)

i need help quick plssss
Answer:
140°
Step-by-step explanation:
∠ABC is an inscribed angle and its measure is half the measure of the intercepted arc, which is arc AC
Therefore the measure of arc AC is 2(70) = 140°
∠AOC is a central angle and its measure is equal to its intercepted arc, which is arc AC.
So, m∠AOC = 140°
The angle AOC from the given circle is 140°. Therefore, option C is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference. More simply, the angle at the center is double the angle at the circumference.
From the given circle, angle ABC is 70°.
Here, 2∠ABC=∠AOC
∠AOC=2×70°
∠AOC=140°
Therefore, option C is the correct answer.

A bookstore sells art books for $25 each. There are 16 books at the store. Identify the graph that represents this situation.
Step-by-step explanation:
I believe its the one on the top of the second picture because if there is only 16 books they can sell then thats the only one that makes sence hope this helped
Graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A bookstore sells art books for $25 each. There are 16 books at the store.
Let x be the total number of books sold and y be the total amount earned:
The linear equation can be framed as follows:
y = 25x
After plotting the graph of the above linear equation we will get a graph exactly the same as mentioned in the graph third.
Thus, the graph third represents the situation if a bookstore sells art books for $25 each. There are 16 books at the store option (C) is correct.
