A jar contains only nickels, dimes and quarters. There is at least one of each type of coin in the jar. If the total value of the coins in the jar equals 60 cents, how many quarters are in the jar?

Answers

Answer 1

Answer: There is 1 quarter in the jar

Step-by-step explanation:

First, we see that there needs to be at least one coin of each; a nickel, a dime, and a quarter.

5+10+25=40 (cents)

A quarter is worth 25 cents, and the total value is only 60, so it is impossible for the quarter value to be more than one, otherwise breaking the total value of 60 cents.

TIME REMAINING 01:37:16 Absalom states that 0 is a rational number. Which is a correct explanation for this statement? The number 0 is a whole number, which is part of the rational numbers. The number 0 is the center of the number line. The number 0 is a natural number, which is part of the rational numbers. The number 0 cannot be written as a fraction.

Answers

Answer:

The number 0 is a whole number, which is part of the rational numbers, is correct.

Step-by-step explanation:

Absalom states that 0 is a rational number.

As the whole numbers are 0,1,2,3,... which is starting from 0, so the stated number 0 is a part of the whole number.

As all the whole number are rational numbers, so 0 is a rational number

Hence, the explanation (i) which is,

The number 0 is a whole number, which is part of the rational numbers, is correct.

The naturals numbers are 1,2,3,... which starts from 1, so 0 is not a part of the natural number, and the number 0 can be written as a fraction like [tex]0=\frac {0}{1}[/tex].

Hence, statement (ii) The number 0 is a natural number, which is part of the rational numbers as well as the statement (iii) The number 0 cannot be written as a fraction, are wrong.

Answer:

The number 0 is a whole number, which is part of the rational numbers.

What is the midpoint between (2,4) and (10,16)?

Answers

Answer:

the midpoint would be (5,9)

Answer:

(6, 10 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1+y_{2} } }{2}[/tex] )

Here (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (10, 16) , thus

midpoint = [tex]\frac{2+10}{2}[/tex], [tex]\frac{4+16}{2}[/tex] ) = ( [tex]\frac{12}{2}[/tex], [tex]\frac{20}{2}[/tex] ) = (6, 10 )

B.9, 4, −1, −6
C.−5, −45, −405, −3645
D. 9, −45, 225, −1125

Answers

Answer:

A

Step-by-step explanation:

For the sequence, the defining formula is given as;

an = Previous term + 9

So a2 will be -5 + 9 = 4

a3 will be 4 + 9 = 13

a4 will be 13 + 9 = 22

a5 will be 22 + 9 = 31

So the sequence of numbers will be;

-5, 4 , 13 , 22 , 31

Bella invested $1000 this past year and earned $110 in interest. Bella's investment portfolio was made up of two items: stocks, which earned 15% interest, and bonds, which earned 7% interest. How much money, in dollars, did Bella invest in stocks this year? Enter your answer as a number with two decimal places.

Answers

Answer: Bella invested $500 in first and $500 in second stock this year.

Step-by-step explanation:

Given: Total principal amount = $1000

Interest = $110

For first year , interest = P x r  , where P= principal , r= rate of interest ( in decimal)

For first bond , interest rate=  15% = 0.15

Let P = x

Interest = 0.15x

For second bond ,  interest rate=  7% = 0.07

Let P = 1000-x

Interest = 0.07(1000-x)=70-0.07x

Now, [tex]0.15x+70-0.07x=110[/tex]

[tex]\Rightarrow\ 0.8x=40\\\\\Rightarrow x=\dfrac{40}{0.08}\\\\\Rightarrow x=500[/tex]

Also, 1000-x = 1000-500=500

Hence, Bella invested $500 in first and $500 in second stock this year.

There will never be a number of tickets where the price for a given number of club members is the same for the same number of non-members.

However, if two club members purchase tickets, their cost is 2($3) = $6.

Sarah has $12.45 in quarters and nickels. She has 39 more nickels than quarters.

How many of each coin does she have?

Answers

Answer:

There are 14 nickes, 24 dimes and 48 quarters

Step-by-step explanation:

let x represent the number of nickels.

As she has 10 more dimes than nickels, the number of dimes is x + 10.

As she has twice as many quarters as dimes, the number of quarters is 2(x + 10)

the total value is $15.10, so I get an equation:

0.05x + 0.1*(x + 10) + 0.25*2(x + 10) = 15.10

0.05x + 0.1x + 1 + 0.5x + 5 = 15.10

0.65x = 9.1

x = 14

x + 10 = 24

2(x + 10) = 48

Jason went to his local zoo that featured 38 reptile exhibits. If these reptile exhibits make up 95% of the zoo's exhibits, then how .any exhibits does the zoo have in total

Answers

Answer:

40 exhibits

Step-by-step explanation:

First, we will what we have gotten into fractions.

There are 38 reptile exhibits, but we dont know how much exhibits there is total, so we will make the total x: 38/x

We know that a percent is out of 100, so our fraction for the percent is 95/100

Now we are going to cross multiply 38/x and 95/100

38 * 100 = 3800

x * 95 = 95x, so 3800 = 95x

Divide both sides by 95 and you get 40.
