Answer:

Question 1: each corresponding term in #2 is the term in #1 * 3.Question 2: answer D

Step-by-step explanation:

Question 1: the defined rules dictates that series 1 is multiples of 3 and series 2 is multiples of 9, making the ratio always 3.

Question 2: You must pay attention to the values of the coins based on how many going from 0 to 3 so the nickels are 0, 5, 10, 15 and the values of dimes is 0, 10, 20, 10. Looking only at the values one could easily jump to answer A because the values initially double for each, but breaks down at 3 coins.

Find the area of the figure.

Answers

9514 1404 393

Answer:

  7 square inches

Step-by-step explanation:

We take the "3 in" dimension at the left to be the length of the line segment below the 1" square, so the height of the right triangle is 3+1 = 4 in.

The triangle area is ...

  A = 1/2bh

  A = 1/2(3 in)(4 in) = 6 in²

The square area is ...

  A = s²

  A = (1 in)² = 1 in²

Then the total area of the figure is ...

  1 in² + 6 in² = 7 in²

Step-by-step explanation:

If you mean 15% by 0.15 then the probability that it will not rain is 85% because, 100-15=85.

If you mean 0.15% by 0.15 then the probability that it will not rain is 99.85% because, 100-0.15 is 99.85.

13. A bag contains 8 red marbles, 4 purple marbles, 5 green marbles, 2 orange, and 1 blue
marbles. One marble is selected and replaced. A second marble is selected. Find the
probability of each compound event. Show work and simplify your solutions.
a)
Not selecting an orange marble and then a blue marble
b)
Selecting a green or red marble and then a purple marble

Answers

Answer:

a) 9 / 200

b) 13 / 100

Step-by-step explanation:

a) The two events are independent because they do not depend each other since the marbles are replaced. To find the total probability of two independent events, you multiply the probability of each event together.

Probability is represented by the amount of desirable outcomes over the total number of outcomes. The total would be the number of marbles, which is: 8 + 4 + 5 + 2 + 1 = 20 outcomes. The number of orange marbles is 2, so the outcomes where you do not pick orange are 20 - 2 or 18 outcomes. The probability of not picking an orange marble would be 18 / 20 or 9 / 10 (using the formula for probability).

There is one outcome where we can pick a blue marble, so the probability of picking a blue marble is 1 / 20. Now, we need to multiply the probabilities for each event: 1 / 20 * 9 / 10  = 9 / 200

b)There are 5 green marbles and 8 red marbles, so the the total outcomes where you pick green or red is 13. We put that over our total to get 13 / 20.

There are 4 purple marbles, so the probability of picking purple is 4 / 20 or 1 / 5. Now we multiply the two probabilities to get the total probability: 1 / 5 * 13 / 20 = 13 / 100

Answers

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be xProfit and Lost be y .

According to the Question :-

[tex]:\implies[/tex] 460 = x + y ( Profit)

[tex]:\implies[/tex] 400 = x - y ( Loss)

Adding both :-

[tex]:\implies[/tex] 460 + 400 = x + y + x - y

[tex]:\implies[/tex] 860 = 2x

[tex]:\implies[/tex] x = 860/2

[tex]:\implies[/tex] x = 430

Hence the Cost price of the watch is 430 .

fred has 15000 in his savings account with an interest rate of 1.8%. assuming he doesn't add or subtract from this amount, find the estimated account balance after 22 years

Answers

Answer:

A = $20,940

Step-by-step explanation:

Interest = Principal x Rate x Time

I = prt

I = 15000(.018)(22)

I = 5940

Interest = $5,940

Total Amount = Principal + Interest

A = P + I

A = 15000 + 5940

A = 20940

2. Landon, Wes, and Tim attempted 25 basketball shots each.
Landon made 36/100 of his shots.
Wes made 2/5 of his shots.
Tim made 32% of his shots.

Who shot the best % and why?
:,)

Answers

Answer: Wes shot the best because his percentage was 40% while Landon (36%) and Tim's (32%) percentage were lower than Wes's.

Step-by-step explanation: The best way to find out who shot the best is by first changing the denominator of the fraction to 25. This way, we can compare easily.

Landon:

36/100=9/25=36%

Wes:

2/5=10/25=40%

Tim:

32%

Alex has a box of pens and pencils. Of all his pens and pencils,

of them are pens. He has
57
pencils.

Part A
Create an equation to represent the total number of pens and pencils,
p
, Alex has.

Answers

Answer:

a. p = n + m

where: n is the number of pens, and m is the number of pencils

b. p = 71

Step-by-step explanation:

Let the number of pens  and pencils that Alex has be represented by n and m respectively.

But,

number of pens, n = 14

number of pencils, m = 57

Then,

total number of pens and pencils, p = number of pens + number of pencils

i.e p = n + m

p = 14 + 57

p = 71

The total number of pens and pencils that Alex has is 71.
