In a class of 42 students, 18 students are in the Math Club, 5 students
are in both the Math Club and the Science Club, and 14 are in neither. How many
students are in the Science Club?
Answers
Answer:
15 maybe?
Step-by-step explanation:
42 - 14 = 28
18 - 5 = 13
28 - 13 = 15
subtract the 14 because it says it is in neither.
Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.
Subtract 13 from the 28 because those 13 are in math and wont be in science also.
Can yall give me 4 examples of rules of exponents with answers pls?
Answers
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]

Could someone please find the rate and y-intercept for these two points? (2,2) and (3,4) the help would be greatly appreciated!!
Answers
so a formula most commonly used is (y^1-y^2)/(x^1-x^2)
m= (y^1-y^2)/(x^1-x^2)
=m=(4-2)/(3-2)
=m=2/1
2/1 can also be expressed as just 2 since anything divided by 1 is just itself
Now use the formula y=mx+b to find the y intercept
use either of your two given point to susitute y and x
y=mx+b
Substitute your values
=(4)=(2)(3)+b
Calculate
=4=6+b
Subtract both sides by 6
=-2=b
Therefore the rate of change is 2/1 and the y-intercept is -2

Answers
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

A fruit basket contains only apples and bananas. If there are 8 apples and 13 bananas, what is the ratio of bananas to fruit? Select all that apply. 13:8
Answers
Answer:
The ratio of bananas to total fruit is 13:21
Step-by-step explanation:
Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.
Answer: 13:21
Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.
Answers
Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes

Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.
How many loaves of banana bread can she make?
Answers
Answer:
69 loaves
Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)
First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.
So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread
70.57 loaves of banana bread
Explaintion:
1,623 ➗ 23 = 70.5652173913043
Rounded: 70.57
