Rashad took a test with 75 multiple - choice questions. If he got 9 questions incorrect,what is the ratio of the questions he got correct to the questions he got incorrect.
Step-by-step explanation:
If he got 9 questions wrong on a 75 multiple choices test, that means he got 66 right. That means the ratio to the questions he got correct to the questions he got incorrect is 66:9, or 22:3 simplified.
Kenny bought a 50-pound bag of chicken feed for $29.98 and a 25-pound bag for $15.49. Can you use proportional reasoning to find the price of a 40-pound bag? Explain.
Yes; The ratio of pounds to cost is equivalent.
Yes; The unit rates are the same.
Yes; The line containing these two points passes through the origin.
No; There is no constant of proportionality.
Answer:
No; There is no constant of proportionality.
Step-by-step explanation:
29.98 divided by 50 is 0.5996 and 15.49 divided by 25 is 0.6196. They are not proportional nor are they equal. There is a difference of 0.02.

Which event will have a sample space of S = {h, t}?
Flipping a fair, two-sided coin
Rolling a six-sided die
Spinning a spinner with three sections
Choosing a tile from a pair of tiles, one with the letter A and one with the letter B
Answer: The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive (i.e., they cannot occur simultaneously).
Step-by-step explanation: All we have to do is multiply the events together to get the total number of outcomes. Using our example above, notice that flipping a coin has two possible results, and rolling a die has six possible outcomes. If we multiply them together, we get the total number of outcomes for the sample space: 2 x 6 = 12!
Answer: A: Flipping a Flair, two-sided coin

What is the product?
−0.05⋅2412
Answer:
-1.225
Step-by-step explanation:
You basically multiply both numbers together.
The product of the given expression is -1.225
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that expression
−0.05 x 24 1 /2
We have;
−0.05 x 45/2
= -1.225
Hence, The product of the given expression is -1.225

Find the constant of proportionality.
Use the constant of proportionality to write a unit rate for the data in the table.
Write an equation to represent the relationship between time, t, and distance, d.
Answer: Constant of proportionality is 45 miles per hour.
Step-by-step explanation: To find the constant of proportionality you need to do miles/hours. It is always easier to do the first one as it is the smallest and thus eliminates the need to do harder problems.
miles/hours
90/2 = 45
135/3=45
225/5=45 and so on...

What one is this one??
Answer:-56
Step-by-step explanation:
bc the 7 is negativ and the 8 is positive
Answer:
-56
Step-by-step explanation:
we multiply just like we are multiplying 2 positive numbers
7 times 8 is equal to 56
Now to figure out if it is negative or positive
The rule is if they both have the same signs it is positive but if they are different it is negative
Like a negative times a negative is positive
A positive times a positive if positive
A negative times a positive is negative which we see in this case so it’s -56

Answer:
Step-by-step explanation:
1: 14.03 x 0.8 = 11.224
14.03 ÷ 0.8 = 17.5375
So, 14.03 x 0.8 < 14.03 ÷ 0.8
2: 6.032 + 1.75 = 7.782
10.142 - 2.36 = 7.782
So, 6.032 + 1.75 = 10.142 - 2.36
3: 578 ÷ 34 = 17
414 ÷ 18 = 23
So, 578 ÷ 34 < 414 ÷ 18
4: 271 ÷ 8 = 33.875
15.05 + 18.825 = 33.875
So, 271 ÷ 8 = 15.05 + 18.825
5: 5.07 x 2.8 = 14.196
19.06 - 4.865 = 14.195
So, 5.07 x 2.8 > 19.06 - 4.865
