Katherine and Ivan had 96 marbles in all. Katherine lost 24 marbles to Ivan
during a game. At the end of the game, Ivan had twice as many marbles as
Katherine. How many marbles did Ivan have at first?

Answers

Answer 1

K. 48-24=24

I. 48+24=72×2= (144) so 144

Answer 2

An equation is formed of two equal expressions. The total number of marbles that Ivan had at the first is 40.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of marbles with Katherine be represented by k, while the number of marbles with Ivan is represented by x.

Given that the total number of marbles available with Katherine and Ivan is 96. Therefore, we can write,

k + x = 96

Solving the equation for k,

k = 96 - x

Further, Katherine lost 24 marbles to Ivan during a game and at the end of the game, Ivan had twice as many marbles as Katherine. Therefore, we can write the equation as,

2(k - 24) = (x + 24)

2k - 48 = x + 24

Substituting the value of k,

2(96 - x) - 48 = x + 24

192 - 2x - 48 = x + 24

192 - 48 - 24 = x + 2x

3x = 120

x = 120/3

x = 40

Hence, the total number of marbles that Ivan had at the first is 40.

Answers

Using the probability concept, it is found that there is a 0.6087 = 60.87% probability of a puppy having no spots.

A probability is the number of desired outcomes divided by the number of total outcomes, that is:

[tex]p = \frac{D}{T}[/tex]

In this problem:

There are 6 + 8 + 4 + 5 = 23 puppies, thus [tex]T = 23[/tex].6 +8 = 14 have no spots, thus [tex]D = 14[/tex]

Then, the probability is:

[tex]p = \frac{D}{T} = \frac{14}{23} = 0.6087[/tex]

0.6087 = 60.87% probability of a puppy having no spots.

Garrett's coin bank contains 500 nickels,
dimes, and quarters. He has the same
number of nickels as dimes, and the total
value of the coins is $72.50. How many
quarters does he have?

Answers

Step-by-step explanation:

d = number of dimes

n = number of nickels

q = number of quarters

d + n + q = 500

d×$0.10 + n×$0.05 + q×$0.25 = $72.50

n = d

we are focusing now on one variable (let's try d), and we are transforming the other equations to express the other variable by this one variable.

since n = d we have already

d + d + q = 500

2d + q = 500

q = 500 - 2d

with that we go into the main equation

d×0.10 + d×0.05 + (500 - 2d)×0.25 = 72.50

d×0.15 + (500 - 2d)×0.25 = 72.50

d×0.15 + 500×0.25 - 2d×0.25 = 72.50

d×0.15 + 125 - d×0.50 = 72.50

-d×0.35 = -52.50

d = 52.50/0.35 = 150

n = d = 150

q = 500 - 2d = 500 - 2×150 = 500 - 300 = 200

so, he has 200 quarters.

Which pair of numbers are not opposites?

17 and – 17

71 and - 71

Answers

Answer:

The answer is C, 17 and | -17|

Step-by-step explanation:

We can solve this using the process of elimination.

Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.

17 and -17 are opposites, since the opposite of a positive is a negative.

The last one is the same. 71 and -71 are opposites. That leaves us with C.

Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.

The answer is 17 and |-17| because they both equal positive 17.

Tommy has $350 of his graduation gift money saved at home, and the amount is modeled by the function h(x) = 350. He reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)x−1. Explain how Tommy can combine the two functions to model the total amount of money he will have in his bank account as interest accrues after he deposits his $350. Justify your reasoning.

Answer:

So the functions that are given are the following:
