Fred bought 4 new baseball cards to add to his collection. The next day his dog ate half of his collection. There are now only 33 cards left. How many cards did Fred start with ?

Answers

Fred started with 62 cards.

We have to work backwards; he has 33 cards left because his dog ate half of his collection. If we multiply 33 and 2 (which will be how much he had BEFORE half was eaten), we get 66. That is after 4 new baseball cards were bought. We need to subtract 4 from 66 in order to see what he originally had, making that 62 cards!

A student earned the scores in the data set in one course. {78, 64, 74, 92, 67} What is the mean of the scores?

Answers

Answer: The mean is 75

Step-by-step explanation:

- You add the scores in the data:

78+64+74+92+67 = 375

- Then divide by the number of scores in the data:

there are 5 scores in the data,

1) 78

2) 64

3) 74

4) 92

5) 67

- So:

375/5 = 75 <--- mean

Answer: 75

To calculate mean or average from a data set, add all the data points together and then divide by the number of points you added together.
In this case,
78+64+74+92+67= 375/5= 75

Write an exponential function to model the data in each table. Identify the growth or decay factor. (23) Picture

Answers

The model of the exponential functions show that

23: table 1 is a decay with a rate of 50%24. tables 2 is a growth with a rate of 10%

How to write exponential function to model the data in each table

Considering the given problem, f(x) = a(b)^x

the starting = a

the base = b

the exponents = x

23. Table 1

At x = 0

f(x) = a(b)^x

(b)^0 = 1

solving for a

4 = a * (b)^0

4 = a

At x = 1

f(x) = a(b)^x

(b)^1 = b

substituting known variables

2 = 4(b)^1

b = 2/4

b = 0.5

for decreasing rate, b = 1 - 0.5 = 0.5

rate, r = 50%

24. Table 2

At x = 0

f(x) = a(b)^x

(b)^0 = 1

solving for a

100 = a * (b)^0

100 = a

At x = 1

f(x) = a(b)^x

(b)^1 = b

substituting known variables

110 = 100(b)^1

b = 110/100

b = 1.10

for increasing rate, b = 1 + r = 1.10, r = 0.10

rate, r = 10%

The base is what determines exponential growth or decay

consider the decimal -0.022 . what is the decimal as a simplified fraction?

could you also explain how you got your answer you dont have to but it would be helpful :))))

Answers

Answer:

-11/500

Step-by-step explanation:

-0.022

To change the decimal number into a fraction, start by reading the number.

The second 2 is in the thousandths place. This number is read as:

"negative twenty-two thousandths"

Now write a fraction with 22 over 1000, and with a negative sign.

-0.022 = -22/1000

Now we reduce. 22 and 1000 are divisible by 2.

-0.022 = -22/1000 = -11/500

-11/500

Charles is in charge of cooking broccoli and zucchini for a large group. He has to spend all $20.10 he has and can carry 11 pounds of veggies. Zucchini costs $1.60 per pound and broccoli costs $2.10 per pound. How many pounds each of zucchini and broccoli can Charles get so that he spends all $20.10 and gets 11 pounds of veggies? Let x represent the number of pounds of zucchini and y represent the number of pounds of broccoli. Show ALL work!

Answers

Answer:

Total equation: X + Y = 11 pounds

Cost equation: 1.60X + 2.10Y = 20.10

Number of Pounds of Zucchini = 6

Number of Pounds of Broccoli = 5

Step-by-step explanation:

You get the equations by just pulling the information from the text.

We then take the total equation and rearrange it to solve for one of our values. I will be using X

X + Y = 11 so first subtract X from both sides to get

Y = 11 - X so now we know what Y equals

next take the cost equation and input X in wherever it shows up so

1.60 (X) + 2.10 (11 - X) = 20.10

now distribute 2.10 to the values in the parathesis to get

1.60X + 23.1 - 2.10X = 20.10

now combine like terms

-0.5X + 23.1 = 20.10

now subtract 23.1 from both sides

-0.5X = -3

now divide both sides by -0.5

X = 6

so now we know that he both 6 pounds of zucchini now plug that into the total equation

6 + Y = 11

subtract 6 from both sides

Y = 5

Answer:

16.449 = 16.4

9.84 = 9.8

by estimating = 26.2

Answer:

16.5+9.8=26.3

Step-by-step explanation:

The equation is 16.449+9.84. We need to add these together after we round them to the nearest tenth. Well with decimals it goes ones, tenths, hundreths. So The second number past the decimal on the right side, is the one that we are rounding. If the number is greater than 5 then we move the number to the next tenth value.If its less than f5 we do the complete opposite.

16.449 is going to be rounded to be 16.5.

9.84 is going to be rounded to be 9.8

Now that our numbers are rounded we can add them.

16.5+9.8=26.3

I hope this helps!!!

The model of the exponential functions

f(x) = 100(0.95)ˣg(x) = 20(1.05)ˣf(x) = g(x) at x = -46.53

f(x) = 40(1.25)ˣg(x) = 10,000(0.84)ˣf(x) = g(x) at x = 113.11

How to model each pair of the functions with exponential function

Considering the given problem, f(x) = a(b)^x

the starting = a

the base = b

the exponents = x

25.

F: initial value of 100 decreasing at a rate of 5%

a = 100, rate, r = 5%, b = 1 - 0.05 = 0.95

f(x) = 100(0.95)ˣ

G: initial value of 20 increasing at a rate of 5%

a = 20, rate, r = 5%, b = 1 + 0.05 = 1.05

g(x) = 20(1.05)ˣ

solving for f(x) = g(x)

20(1.05)ˣ = 100(0.92)ˣ

divide through by 20

(1.05)ˣ = 5(0.92)ˣ

x㏒(1.05) = ㏒(5 + (0.92)ˣ)

x㏒(1.05) = ㏒5 - x㏒0.92

x㏒(1.05) + x㏒0.92 = ㏒5

-0.015x = ㏒5

x = -46.53

26.

f: initial value of 40 increasing at a rate of 25%

a = 40, r = 25%, b = 1 + 0.25 = 1.25

f(x) = 40(1.25)ˣ

g: initial value of 10,000 decreasing at a rate of 16%

a = 10,000, r = 16%, b = 1 - 0.16 = 0.84

g(x) = 10,000(0.84)ˣ

solving for f(x) = g(x)

40(1.25)ˣ = 10,000(0.84)ˣ

divide through by 40

(1.25)ˣ = 250(0.84)ˣ

x㏒(1.25) = ㏒(250 + (0.84)ˣ)

x㏒(1.25) = ㏒250 - x㏒0.84

x㏒(1.25) + x㏒0.84 = ㏒250

0.0212x = ㏒250

What is a mixed fraction?

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder.

So, a mixed fraction is a combination of a whole number and a proper fraction.

According to the given question:

Gina's relative time list is [tex]-1\frac{2}{3}[/tex] , -1.45, -1.8, [tex]-1\frac{3}{8}[/tex]

Converting mixed fractions to decimal forms to make comparison easy.

-1 2/3 = -1 + 2/3 = - 1.6 min

-1 3/8 = -1 + 3/8 = -1.375 min

Hence the new list is - 1.6, - 1.45, - 1.8, - 1.375

Arranging from least to greatest as follows

-1.8 < - 1.6 < - 1.45 < - 1.375

- 1.8 < -1 2/3 < -1.45 < -1 3/8

Which of the following inequalities matches the graph? (1 point)

graph of an inequality with a solid vertical line through the point 5, 0 and shading to the left of the line

x ≤ 5

x ≥ 5

y ≤ 5

y ≥ 5

Answers

Answer: The inequality that matches the graph is x ≤ 5. This is because the graph has a solid vertical line at x = 5 and the shading is to the left of the line. This indicates that all values of x that are less than or equal to 5 satisfy the inequality.

The inequality x ≥ 5 would not match the graph because the shading would be to the right of the line. The inequalities y ≤ 5 and y ≥ 5 do not match the graph because they are not in the correct form. Inequalities involving y have a graph with a horizontal line, not a vertical line.
