1. How many 2-digit numbers are multiples of both 5 and 7?
2. How many 2-digit numbers are multiples of either 5 or 7?
thanks!!!!!
Answer and Step-by-step explanation:
1.
First, we need to find what numbers 5 and 7 both go into, and are 2-digits.
5 and 7 go into the numbers 35 and 70.
So, that means the amount of numbers 5 and 7 go into and are 2-digits is Two Numbers.
2.
Now, we have to find the amount of numbers 5 goes into and the amount of numbers 7 goes into, and they need to be 2-digits.
5 goes into the numbers 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, and 95. -- 18 numbers
7 goes into the numbers 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, and 98. -- 13 numbers.
n(A) = 18 n(B) = 13
Now, the set of 2-digit numbers that are multiples of both 5 and 7 is given by
A∩B = {35, 70} ⇒ n(A∩B) = 2
Therefore, the number of 2-digit numbers that are multiples of either 5 or 7 is given by
n(A∪B) = n(A) + n(B) - n(A∪B) = 18 + 13 - 2 = 29
Now, there are 90 2 -digit numbers.
Thus, the number 2-digit numbers are multiples of neither 5 nor 7 is
90 - 29 = 61.
Hence, the total number of numbers is 61.

would you earn a greater total commission with Sara or Ravi?
The current ratio of Sara's sales to Ravi's sales is 100:2
Sara's pieces of art sell for $25 each your commission is 60%
Ravi's pieces of art sell for $2000 each your commission is 25%
as a professional artist assume you will make pieces of art that sell at the same sales ratio as the artist with whom you apprenticed. would you earn more as a professional after apprenticed for Sara or Ravi?
As a professional artist and judging from the current sales ratio and commission rates, one would earn more if one apprenticed for Sara.
Which of Sara and Ravi guarantees more earnings after apprenticeship?As evident in the task content; the current ratio of Sara's sales to Ravi's sale is 100 : 2.
Since Sara's pieces of art sell for $25, the total earnings is; 25 × 100 = $2500.
Hence, since the commission rate is 60%, it follows that the commission earned on sales of Sara's pieces is; 60% of 2500 = 0.6 × 2500 = $1500.
Also, since Ravi's pieces each cost $2000, it follows that for 2 pieces, the total earnings is; 2 × $2000 = $4,000.
Hence, since the commission rate for Ravi's pieces is 25%, the commission earned is therefore; 25% of 4000 = 0.25 × 4000 = $1000.
On this note, one would earn more if one apprenticed for Sara.

Find the area of the right triangle below.

Area = 1/2*base*height = 1/2*9*4 = 18 sq.m
The length and breadth of the three rectangles are as given below:(a) 9 m and 6 m(b) 17 m and 3 m(c) 4 m and 14 mWhich one has the largest area and which one has the smallest?Solution:
We will be using the area of rectangle formula to calculate the areas of the three rectangles given.
(a) Length(l) = 9 m and Breadth(b) = 6 m
Area of rectangle = l × b
= 9 × 6
= 54 m2
(b) Length(l) = 17 m and Breadth(b) = 3 m
Area of rectangle = l × b
= 17 × 3
= 51 m2
(c) Length(l) = 4 m and Breadth(b) = 14 m
Area of rectangle = l × b
= 4 × 14
= 56 m2
Therefore, the area of the rectangle with the dimensions 4m and 14m having an area of 56 m2 that is (c) has the largest area whereas, the area of the rectangle with dimensions 17m and 3m having an area of 51 m2 that is (b) has the smallest area.

What is sample size?
Choosing the number of observations or replicates to include in a statistical sample is the process of determining sample size. Any empirical study whose objective is to draw conclusions about a population from a sample must take the sample size into consideration.
Finding your sample size in five steps
Clarify the term "population size" or "people"
Specify your error margin.
Decide how confident you are.
Calculate the expected variance.
Decide on the sample size.
As long as it doesn't go over 1,000, 10% of the population serves as a good maximum sample size.
The dot plot in option E is correct.
Because we conduct 50 trials, dot plot should have 50 points, one point per each trial.

x = 70 degrees
Step-by-step explanation:
Answer:
x = 70°
Step-by-step explanation:
Because it is an isosceles triangle, the two base angles are the same (55° and 55°)
All triangles angles must add up to 180°, so 180-55-55 will give us the missing angle (x).
180-55-55 = 70

together Larry and Lenny have $\$$35. Larry has two-fifths of Lenny's amount. How many more dollars than Larry does Lenny have
The answer which we get after calculating from the data given is that Larry has 15 dollars more than Lenny.
Let the amount which Lenny is having be x
then the amount which Larry is having will be (2/5)x
and on combining them it makes $35 .
Which means, x + 2x/5 = 35
On simplifying this equation we will get ,
(7/5)x= 35 ,
multiplying both the sides by 5/7
x= (5/7)*35 = $25
Therefore , Lenny is having 4 25.
So Larry must be having , $(35 - 25) = $10
So , we can conclude that Lenny has more dollars. The difference is of 15 dollars.

Like terms for the given data are: 17x² and 3x²; -3xy and -2xy. Combining the like terms we get: 20x² and -5xy
What is like terms?In algebra, the term "equal terms" refers to words with the same variable to the same power.
Similar variables and powers are called similar words in algebra. Matching coefficients is not required. When two or more words do not share the same variable or power, they are called inequal terms.

Finn jumped 200 times in 10 hours. At what rate, how many times would he jumped in 12 minutes?
Answer: 4 times
Step-by-step explanation: I got 4 times. Here's how to solve it:
Set up a proportional relationship, but first, we need to convert 10 hrs into mins:
1 hour = 60 mins
To find how many minutes are in 10 hours, we multiply 60 by 10, which equals 600.
So, therefore there are 600 mins in 10 hours. Now, we can set up our proportional relationship:
[tex]\frac{200}{60} = \frac{?}{12}[/tex]
So, if we know 12 is a factor of 60, we should divide 60 by 12, and we should get 5. So, now we do the same with the 200. We do 200 / 50, and we get 4. I hope this helps!

The entrance fee for the carnival is $7and the cost for a ticket for a
ride is $.25.
a. Write an equation for the total cost (C) if you go to the carnival
and ride r number of rides.
b. What is the total cost if you ride 15 rides?
Answer:
Step-by-step explanation:
Consider the following:
a) y=0.25x+7
b) $10.75
Explanation:
a)
y=mx+b is the slope-intercept form.
B is our Y intercept meaning any fee or initial charge that adds to total cost. In this situation, the initial fee of $7 is our Y-Intercept. . Our mx is the slope. A slope increases based on the amount (x) of certain things you have. In this situation, you are buying maybe 1, 2 or 3 tickets and each ride costs $0.25.
Our x remains the same, that is where we plugin the amount of tickets we will buy (x). The M value is the price per ticket which as said, is $0.25 per. Our slope therefore will be 0.25x.
Combining our Y-Intercept and our Slope will leave us with y (total cost) = 0.25x + 7
b)
We have found our slope, 0.25x+7
Now, we have to plugin our number of rides (x) which is 15.
If done correctly it should be 0.25(15)+7 and that is equal to $10.75 for 15 rides.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The total number of students for the trip = 235 students
The number of buses = 5 buses
The number of students in a bus be = B
Now , each seat on the bus can occupy = 2 students
So , 22 seats can occupy = 22 x 2 students
22 seats in the bus can occupy = 44 students
So , the number of students in a bus B = 44 students
And , the total number of students in 5 buses = 5 x number of students in a bus B
Substituting the values in the equation , we get
The total number of students in 5 buses = 5 x 44
The total number of students in 5 buses = 220 students
So , the remaining number of students A = total number of students for the trip - total number of students in 5 buses
Substituting the values in the equation , we get
The remaining number of students A = 235 - 220
The remaining number of students A = 15 students
Therefore , the value of A is 15 students
Hence , the number of students is 15 students
