A cheetah can run at a speed of 74.56 miles per hour. A racehourse can run at a speed of 38.9 miles per hour. How much faster can a cheetah run than a racehorse in miles per hour?
Answer:
35.66 Mph
Step-by-step explanation:
If I'm correct, how much faster means subtracting which means you should do 74.56 mph minus 38.9 mph which gets you 35.66 mph.

Step-by-step explanation:
The scatter plot shows the height x (in inches) and the weight y (in pounds) of 10 people. Find the weight of the person who is 63 inches tall. Then find the height of the person who weighs 135 pounds.
PLEASE HELP QUICK!!!!
Given:
Scatter plot shows the height x (in inches) and the weight y (in pounds) of 10 people.
To find:
The weight of the person who is 63 inches tall. Then find the height of the person who weighs 135 pounds.
Solution:
In the given scatter plot,
x = height (in inches)
y = weight (in pounds)
First we need to find the weight of the person who is 63 inches tall.
If height of a person is 63 inches, then x = 63.
From the given graph, it is clear that y = 110 at x = 63.
Therefore, the weight of the person who is 63 inches tall is 110 pounds.
Now, we need to find the height of the person who weighs 135 pounds.
If weight of a person is 135 pounds, then y = 135.
From the given graph, it is clear that x = 66 at y = 135.
Therefore, the height of the person who weighs 135 pounds is 66 inches.

1. Compare the strengths and weaknesses of the horizontal and vertical methods for adding and subtracting polynomials. Include common errors to watch out for when using each of these methods.
2. Explain why you cannot use algebra tiles to model the multiplication of a linear polynomial by a quadratic polynomial. As an added challenge, develop a model similar to algebra tiles that will allow you to show this multiplication. Describe an example of your model for the product (x + 1)(x2 + 2x + 2). 3. Imagine that you are teaching a new student how to multiply polynomials. Explain how multiplying polynomials is similar to multiplying integers. Then describe the key differences between the two. 4. If you multiply a binomial by a binomial, how many terms are in the product (before combining like terms)? What about multiplying a monomial by a trinomial? Two trinomials? Write a statement about how many terms you will get when you multiply a polynomial with m terms by a polynomial with n terms. Give an explanation to support your statement.
1.Each method works differently the angles inside them is what matters.
2. Manipulating algebra tiles can help people solve linear equations
3.Distribute each term of the first polynomial to every term of the second polynomial. Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents. But with Integers you multiply two integers with different signs
4.So you know how
A monomial is a number, a variable or a product of a number and a variable.
multiply each term in one polynomial by each term in the other polynomial
Elene rode her bike 2 miles in 10 minutes. She also rode her bike 1 mile in 5 minutes. How many miles did Elena ride in 1 minute? Someone help me please because I have an F in math right now and this question can solve my problems.

The cost to print fliers for the opening of an art show varies directly with the number of copies.
If it cost $45 to print 750 copies, what will be the total cost for 120 more copies?
Answer:
7.2 $
Step-by-step explanation:
45$ : 750 copies = x$ = 120
750x = 120 x 45
750x = 5400
5400 divided by 750 = 7.2

Answer:
1. m - 1 1/2 = -5/4
+1 1/2 +1 1/2 or 6/4
m = 1/4
2. x - 3 = -5 1/2
+3 +3
x = -2 1/2
3. 5 1/2 + p = 6
-5 1/2 -5 1/2
p = 1/2
4. x - 1/2 = 1 1/4
+ 1/2 +1/2 or 2/4
x = 1 3/4

Answer:
13 is two and two thirds of four and seven eighths.
Step-by-step explanation:
To solve this, all you need to do is divide 13 by 2 and two thirds. Let's do it:
[tex]13 \div 2\frac{2}{3}\\= 13 \div \frac{8}{3}\\= 13 \times \frac{3}{8}\\= \frac{13 \times 3}{8}\\= \frac{39}{8}\\= 4\frac{7}{8}[/tex]

If the simple interest on $6,000 for 3 years is $1,620, then what is the interest rate?
Answer:
Interest rate: 9%
Step-by-step explanation:
Using the simple interest formula: A=P(1+rt)
A=Final amount
P=Principal amount
r=rate
t=time (years)
We just need to put in the information we have from the question and solve for r.
7,620=6000(1+r3)
7,620/6000=1+r3
1.27=1+r3
0.27=r3
r=0.09
r=9%
Can somebody help me please? Thank u! :)
Answer:
1. last choice
2. first choice
Step-by-step explanation:
First ImageThe reason why it is the last choice because when times keep going as distance also keeps increasing as well. But the last choice says that run at the end of track then turn around and run back. That means there must be a decreasing distance and a maximum value as well.
Therefore the only with max point/vertex is the absolute value which matches the last choice.
Second ImageFirst choice because the car straight forwards without any change. The car runs with a steady speed but the distance will keep changing without any change of distance.
So the answer is first choice.
