A circle has a diameter of 26 units. What is the area of the circle to the nearest hundredth of a square unit? Use 3.14 for pi. *

Answers

A=pi(r)^2

We have the diameter. To get the radius divide it by 2.

The radius now is equal = 13.
Pi=3.14

Distribute it to the equation... A=3.14(13)^2

The area is equal = 530.66

1 Marlena has a bag of coins. The bag
contains 8 quarters, 10 dimes, 4 nickels,
and 2 pennies. She will randomly select a
coin from the bag. What is the probability
that Marlena will select a nickel? (7.1A,
7.1B, 7.1F)

Answers

Answer:

The probability is 1/6

Step-by-step explanation:

Firstly, we need to get the total number of coins

that would be the sum of all the coins present

We have this as;

8 + 10 + 4 + 2 = 24 coins

The number of nickels is 4

So the probability of selecting a nickel is the number of nickels divided by the total number of coins

We have this as;

4/24 = 1/6

The diameter of a circle is 17 cm. Find the circumference \textit{to the nearest tenth}to the nearest tenth.

Answers

Answer:

52.4 cm

Step-by-step explanation:

Circumference of a circle = 2πr

Radius, r = diameter / 2

= 17 cm / 2

= 8.5 cm

π = 3.14

Circumference of a circle = 2πr

= 2 × 3.14 × 8.5

= 53.38 cm

Approximately 52.4 cm

Answers

Answer:

y = 2x + 6

Step-by-step explanation:

slope-intercept form => y = mx + b

substitute two of the (x, y) into the equations: y = mx + b  to solve for m and b

=> 0 = -3m + b, 6 = 0m + b

6 = 0m + b => b = 6

substitute b = 6 into 0 = -3m + b to solve for m:

=> 0 = -3m + 6 => -3m = -6 => m = 2

plug in b = 6 and m = 2 into the equation y = mx + b:

=> y = 2x + 6

Answer is y= 2x+6 hope it helps:)

Hayden went apple picking with his family. In his bag he had four Granny Smith apples,

that he will pick a Granny Smith apple out of his bag, replace it, and then choose a
Honeycrisp apple? Write your answer as a simplified fraction.

Answers

Answer: [tex]\dfrac{2}{25}[/tex]

Step-by-step explanation:

Given

There 4 Granny smith, 2 Honey crisp, 3 Gala, 1 Fuji apples in the bag

The chance of picking a granny smith apple out of the bag is 4 out of 10 apples

So, the probability of picking it is [tex]\frac{4}{10}[/tex]

now, it is replaced and honey crisp apple is chosen

The probability of happening this event along with the first one is

[tex]\Rightarrow P=\dfrac{4}{10}\times \dfrac{2}{10}\\\\\Rightarrow P=\dfrac{8}{100}=\dfrac{2}{25}[/tex]

Analyze Information The fastest first-round time for the women's 100-meter hurdles in the Olympics was set in 2012 at 12.54 seconds. What digit is in the tenths place? In the hundredths place?

Answers

Answer: 5 is in the tenths place

4 is in the hundredths place.

Step-by-step explanation:

When dealing with the place value of numbers, we should note that the digit is in the tenths place is the first didgut after the decimal point. In the number 12.54, the first digit after the decimal place is 5.

The digit in the hundredths place is the digit that comes immediately after the tenths place. In this case given the number 12.54, the digit in the hundredths place is 4.
