Frank has a jar filled with 200 old dimes. Suppose he selects a dime from the jar without looking. There is a 20% chance that he will draw a dime from the 1960s. How many 1960s dimes are in Frank's jar? Explain your thinking. *

Answers

Answer: 40

Step-by-step explanation:

Given

Jar contains 200 old dimes

Chances to pick the 1960s is 20% i.e. 1960s is 20% of 200 old dimes

So, we can write

[tex]\Rightarrow \text{No of 1960s is }=20\%\ \text{of}\ 200=0.2\times 200\\\Rightarrow \text{No of 1960s is }=40[/tex]

when a number is reduced by 5 it becomes 70% of the number itself find the number​

Answers

Answer: 75%

Step-by-step explanation: When you said a number is reduced by 5, it is 70%. So 70 + 5 = 75%

Answer:

16 2/3

Step-by-step explanation:

x - 5 = 0.7x

x - 0.7x = 5

0.3x = 5

x = 5/0.3 = 16 2/3

check: 50/3 - 5 = 35/3

0.7 x 50/3 = 35/3

The data shown in the table below represents either a linear or an exponential function. Which of the equations below best models this data set?

1) y=5(2)^x
2) y=10(2)^x

x=4

Step-by-step explanation:

1. 2x+4=12

2. 2x+4-4=12-4

3. 2x=8

4. 2x/2=8/2

5. x=4

Answer:

x=4

Step-by-step explanation:

2x+4=12

Step 1: subtract both sides by 4

4-4=0 and 12-4=8

Now you are left with 2x=8

Step 2: divide 2 on both sides

2/2=1x and 8/2=4

Therefore, x=4

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (6, 1280)(6,1280).

Answers

Answer:

[tex]y=20(2)^x[/tex]

Step-by-step explanation:

We want to write an exponential function that goes through the points (0, 20) and (6, 1280).

The standard exponential function is given by:

[tex]y=ab^x[/tex]

The point (0, 20) tells us that y = 20 when x = 0. Hence:

[tex]20=a(b)^0[/tex]

Simplify:

[tex]20=a(1)\Rightarrow a=20[/tex]

So, our exponential function is now:

[tex]y=20(b)^x[/tex]

Next, the point (6, 1280) tells us that y = 1280 when x = 6. Thus:

[tex]1280=20(b)^6[/tex]

Solve for b. Divide both sides by 20:

[tex]64=b^6[/tex]

Therefore:

[tex]b=\sqrt[6]{64}=2[/tex]

Hence, our function is:

[tex]y=20(2)^x[/tex]

The area of the rectangle shown is 13 ft2.
Find the length and the width of the rectangle.

Answers

Answer:

26

Step-by-step explanation:

13x2=26 you can also do 13+13=26 if easier

The length and width would be the same 3.25ft because you divide 13/2=6.5 now divide 6.5/2=3.25 and double check by multiplying 3.25x4(all sides)=13ft^2

1. What is the measure of angle B04?
2. What is the measure of angie BDA?
3. What is the measure of angle BCA?

Answers

Using the inscribed angle theorems, the measure of the indicated angles are:

1. m∠BOA = 30°

2. m∠BDA = 15°

3. m∠BCA = 15°

What is the Inscribed Angle Theorems?

Based on the inscribed angle theorems, the following relationships are established:

Inscribed angle = 2(measure of intersected arc)Central angle = measure of intersected arc

Given:

Intercepted arc BA = 30°

1. ∠BOA is central angle

Thus:

m∠BOA = 30° (inscribed angle theorems)

2. ∠BDA is inscribed angle.

m∠BDA = 1/2(30) = 15° (inscribed angle theorems)

3. m∠BCA = m∠BDA  = 15° (inscribed angle theorems)

what is common for all machines help how do I explain the story is basically about a old couple and a storyteller gives them a mill, the mill will give u whatever u want it to give u. For example, If u say the command, and say what u want, it will give it to u. But, if u want it to stop, u have to command it to stop. So one day the old couple went out and never locks their door, and their neighbors next door are ungrateful because the old couple have nice clothes and they eat good food while the neighbors next door, dont. The neighbors heard the old man say the command to the mill and the neighbors saw the mill give the old man what he wanted, so the neighbors decided to steal the mill. The neighbors then leave to somewhere nobody knows them and the neighbors wanted salt so they said the command, but they dont know the command to stop it.
