Circumference is found by multiplying the diameter by PI.

Since the circumference is given in terms of PI, the diameter is the number given.

The diameter is 144 feet.

Answer:

144

Step-by-step explanation:

when u find curcumference, u multiply the diameter by pi. so to simplify 144(pi), you divide by pi leaving u with 144

The formula for area of a triangle is: 1/2 x base x height.

You are given the height of 4 and the area of 4.

Replace those in the formula and solve for x ( base)

4 = 1/2 x base x 4

Divide both sides by 4:

t=-148+1/1.5740740740741

Step-by-step explanation:

(t)=-0.32+2.7t+253

We move all terms to the left:

(t)-(-0.32+2.7t+253)=0

We add all the numbers together, and all the variables

t-(2.7t+252.68)=0

We get rid of parentheses

t-2.7t-252.68=0

We add all the numbers together, and all the variables

-1.7t-252.68=0

We move all terms containing t to the left, all other terms to the right

-1.7t=252.68

t=252.68/-1.7

t=-148+1/1.5740740740741

Answer: t=-148+1/1.5740740740741

Answer:

1. 1/4

2. 1/2

Step-by-step explanation:

If there are equal numbers of males and females, we can simplify that by saying there's one male and one female for each coat color.

1. What's the probability that both are males?

Well, there's a 1/2 chances the light-colored coat bear is a male and there's also a 1/2 chances the dark-colored coat bear is a male.  So, we can make this reference table:

Light             Dark

Male             Male

Male             Female

Female         Male

Female         Female

As you can see, the probability that both of the spotted bears are males is 1/4 (1/2 * 1/2).

2. If the light-colored bear, what are the odds both are males?

If we know for sure the light-one is male, then there's 1/2 chances the other is too, refer to the table above to verify.

She must sell as least 20 candles

Step-by-step explanation:

Sharon has 50 dollars

She makes 2 dollars per candle

Money in 50+2c

She needs at least 90

90≤ 50+2c

We need to solve this inequality

Subtract 50 from each side

90-50≤ 50-50+2c

40 ≤ 2c

Divide by 2

40/2 ≤ 2c/2

20 ≤ c

She must sell as least 20 candles

90-50=40 40 divided by 2 = 20. sharon needs to sell 20 candles

Answer

D.  -3 and 4

ANSWER

D. -3 and 4

EXPLANATION

The given quadratic trinomial is

[tex] {x}^{2} + x - 12[/tex]

To factor this we need to find two factors of -12 that sum up to 1, the coefficient of x.

We can see from the table that, when p=-3 and q=4, then p+q =1.

The trinomial can now be factored as:

[tex] {x}^{2} + x - 12 = (x - 3)(x + 4)[/tex]

Answer:

For any question like this you take the number of ways an event can happen (odd number) and divide by the total number of possibilities (sides of a die). If you assume a six sided die there are 3 odd numbers, 1,3, 5. And 6 total sides, so 3/6 = 1/2 or 50%.

Step-by-step explanation:

Final answer:

The probability of rolling an odd number and then a number greater than 5 on a six-sided die in sequence is calculated by multiplying the two independent probabilities, resulting in a combined probability of 1/12.

Explanation:

The student wants to know the probability of landing on an odd number and then landing on a number greater than 5 when rolling a six-sided die. To solve this problem, we need to consider the two separate events independently and then calculate the combined probability.

First, let's consider the probability of landing on an odd number. There are three odd numbers on a die: 1, 3, and 5. Since each outcome is equally likely, the probability is the number of favorable outcomes over the number of possible outcomes, which is P(odd number) = 3/6 = 1/2.

Next, we calculate the probability of landing on a number greater than 5, which is only one number, 6. So, P(number > 5) = 1/6.

To find the probability of both events happening in sequence, we multiply the two probabilities: P(odd number) * P(number > 5) = (1/2) * (1/6) = 1/12. Therefore, the probability of rolling an odd number and then a number greater than 5 is 1/12.

Answer:

333,333$

Step-by-step explanation:

15% goes into 100% 6-2/3 times

50,000 x 6-2/3 = 333,333

To find the cost of the house, we can start by setting up an equation. Let \( D \) be the deposit and \( C \) be the cost of the house. We know that the deposit represents 15% of the total cost of the house. Therefore, we can write this relationship as:
\[ D = \frac{15}{100} \times C \]
Given that the deposit \( D \) is $50,000, the equation becomes:
\[ 50,000 = \frac{15}{100} \times C \]
To solve for \( C \), the cost of the house, we will isolate \( C \) on one side of the equation. We can do this by dividing both sides of the equation by 0.15 (which is the decimal representation of 15%):
\[ C = \frac{50,000}{0.15} \]
Now let's calculate this:
\[ C = \frac{50,000}{0.15} = 333,333.\overline{3} \]
The result is approximately $333,333.33. Since we are asked to round to the nearest dollar, we look at the hundredth's place, which is a 3, and since it is less than 5, we round down the dollar amount.
So, the cost of the house rounded to the nearest dollar is $333,333.

Answer:

A) Ni Hua visited 12 islands and 7 peninsulas.

Step-by-step explanation:

If all visits had been to islands, Hua would have skydived 19·2 = 38 times. He actually skydived 45-38 = 7 times more than that. Each peninsula that replaces an island adds 1 skydive to his total, so he must have visited 7 peninsulas.

Hua visited 7 peninsulas and 12 islands.

Answer:

Therefore, the plant that grew at a faster rate would be Megan’s at 2.5 inches per week.

Step-by-step explanation:

Megan's rate = 12 - 4.5 / 4 -1 = 2.5 inches per week

Suzanne's rate = 11 - 5 / 4-1 = 0.5 inches per week

Without the actual growth measurements, we cannot make a comparison or identify which plant grew faster.

Using the examples:

Suzanne's plant grew at a faster rate (1.5 inches/week) compared to Megan's plant (1 inch/week).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To determine whose plant grew at a faster rate and what was the rate, we need information about the growth of their plants over the four-week period.

Without this information, we cannot determine the rate of growth or compare the rates of growth of their plants.

Assuming that we have the required information about their plant growth, we can compare the rates of growth of their plants by calculating the average weekly growth rate of each plant.

The plant with a higher average weekly growth rate grew at a faster rate.

For example:

If Megan's plant grew by 4 inches over four weeks, its average weekly growth rate would be:

The average weekly growth rate of Megan's plant = (Total growth in 4 weeks) / (Number of weeks)

= 4 inches / 4 weeks

= 1 inch/week

Similarly,

If Suzanne's plant grew by 6 inches over four weeks, its average weekly growth rate would be:

The average weekly growth rate of Suzanne's plant = (Total growth in 4 weeks) / (Number of weeks)

= 6 inches / 4 weeks

= 1.5 inches/week

In this example:

Suzanne's plant grew at a faster rate (1.5 inches/week) compared to Megan's plant (1 inch/week).

Thus,

Without the actual growth measurements, we cannot make a comparison or identify which plant grew faster.
