You flip a coin twice.
What is the probability of getting tails and then getting heads?
Write your answer as a percentage.
___%
Answers
Your answer would be 25%.
Assuming the coin is not biased, the probability of flipping a heads or tails is 1/2 equally. This remains the same no matter how many times you flip the coin, because the outcome of one flip does not affect the outcome of another.
This means that the probability of getting a tails the first flip is 1/2, and the probability of then getting a heads is also 1/2, so to find the probability of both happening you need to multiply these probabilities together, and 1/2 × 1/2 = 1/4, and 1/4 as a percentage is 25%.

The surface area of the prism is 298 square feet. Find the value of x
Answers
Answer:
We can make an equation
2 * 7x + 2 * 4x + 2 * 4 * 7 = 298
14x + 8x + 56 = 298
22x = 298 - 56
22x = 242
x = 242/22
x = 11
If the surface area of the prism is 298 square feet, the value of x is 11 feet.
To find the value of x, we need to use the formula for the surface area of a rectangular prism:
Surface Area (SA) = 2lw + 2lh + 2wh,
where l is the length, w is the width, and h is the height of the prism.
Given that the length (l) is 7 ft and the width (w) is 4 ft, and the surface area (SA) is 298 square feet, we can set up the equation:
298 = 2(7)(x) + 2(7)(4) + 2(4)(x).
Now, simplify the equation:
298 = 14x + 56 + 8x.
Combine like terms:
298 = 22x + 56.
Now, isolate x by moving the constant term to the other side of the equation:
22x = 298 - 56,
22x = 242.
Finally, solve for x:
x = 242 / 22,
x = 11.
In summary, the height of the rectangular prism is 11 feet, and this value is obtained by using the surface area formula and solving the resulting equation.

In 1970, Town A had a population of 800 people and the population increased by 5% each year. In 1970, Town B had a population of 1100 people and the population increased by 50 people each year.
Which town will eventually have the greater population?
Which town had a greater population in 2000?
Answers
Answer:
Town "A" was going to have a larger population eventually
Town "A" = 3458 inhabitants
Town "B" = 2600 inhabitants
Step-by-step explanation:
Eventually Town "A" will have a greater population population because it increases in percentage with respect to each year, therefore, there will come a time that its increase will be greater than 50 per year, which is what Town "B" increases.
To calculate the population the first thing is to know that 30 years have passed, then we must calculate that 30-year increase.
For Town "A" the increase would be as follows:
800 * (1.05 ^ 30) = 3457.55 = 3458 inhabitants
For Town "B" the increase would be as follows:
1100 + 50 * 30 = 2600 inhabitants
Thus checking that Town "A" was going to have a larger population eventually
Answer:
Town A will get eventually have the greater population

Which best describes the error in finding the percent increase from 18 to 26? The denominator should be 18, which is the original amount. The numerator should be 18, which is the original amount. The numerator should be 26, which is the new amount. The denominator should be 18, which is the new amount. The expression was simplified incorrectly. Question 2 Correct the error. Round your answer to the nearest whole number. The percent increase from 18 to 26 is about %.
Answers
Answer:
The percentage increase is 44.44%
What best describes the error is that the denominator should be 18 which is the original amount
Step-by-step explanation:
Here, we are to calculate the percentage increase from 18 to 26
Mathematically, we can calculate this with the following formula;
(New value - old value)/old value * 100%
Where the new value is 26 and the old value is 18. Plugging these values, we have;
(26-18)/18 * 100%
8/18 * 100% = 44.44% increase
The error in finding the percent increase from 18 to 26 is, The numerator should be 18, which is the original amount.
The percentage increase from 18 to 26 is about 44.4%.
We have to give that,
To find the percent increase from 18 to 26.
Now, The process to find a percent increase from 18 to 26 is,
(26 - 18) / 18 x 100%
= 8/18 x 100%
= 800/18%
= 44.4%

Betty saves $161 a month. She saves $141 less each month than Jack. How much will jack save in 2 years?
Answers
Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.
First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.
141 + 161 = 302
Now, that we know how much Jack saves per month.
Then, we have to find out how many months are in 2 years.
We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.
12 x 2 = 24
Therefore, there are 24 months in two years.
Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.
24 x 302 = 7,248
Thus, Jack will save approximately $7,248 in 2 years.
Answer:
Jack will save $7248 in 2 years.
Step-by-step explanation:
Because we know that Betty saves $161 a month, but it's $141 less than Jack saves each month.
Adding $141 to $161 let's us know how much Jack saves.
$141 + $161 = $302
Jack saves $302 each month.
There are 24 months in 2 years.
$302 × 24 = $7248.

Mr. Schultz needs $200 to buy some new Jordan shoes. He was given $75 for his birthday. Which equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes? *
x + 75 = 200
75x = 200
200x = 75
x - 75 = 200
Answers
Answer:
The equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes is 75+x=200
Step-by-step explanation:
Mr. Schultz was given amount on his birthday = $75
We are given that Mr. Schultz needs $200 to buy some new Jordan shoes.
Let x be the amount of money Mr. Schultz needs to save to buy the shoes
So, Total Amount saved = 75+x
Total cost of shoes = $200
So, 75+x=200
So, The required equation is 75+x=200
So, Option A is true
Hence The equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes is 75+x=200

What is the volume of a circle
Answers
Answer:
volume = 4/3 × pi × r^3
Step-by-step explanation:
Answer:
Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
Circumference = 2 • π • radius = π • diameter
Circle Area = π • r² = ¼ • π • d²
The circumference of a circle is directly proportional to its radius. The ratio between a circle's circumference and its diameter is pi, a constant that equals approximately 3.142. The circle's diameter, in turn equals twice the radius. A regular solid that has a circle as a face is called a cylinder. Like all geometric prisms, a cylinder's volume is the product of its cross-sectional area and its length. The cross-sectional area is the area of its circle, and you can calculate it from the circle's radius. Multiply the circle's radius by 2 to calculate its diameter. For instance, if the radius equals 6 inches, compute as follows to determine the diameter: 6 x 2 = 12 inches. Multiply the diameter by pi to get the circle's circumference: 12 x 3.142 = approximately 37.7 inches. Find the square of the radius: 6 x 6 = 36 square inches. Multiply the answer determined in Step 3 by pi to get the circle's area: 36 x pi = 113 square inches. Multiply the circle's area by the cylinder's length to obtain the volume. If the length is, for instance, 10 inches, then compute as follows: 113 x 10 = 1,130 cubic inches.

Boat A is 20 km from port on a bearing of 025° and boat B is 25 km from port on a bearing of 070°. Boat B is in distress. What bearing should boat A travel on to reach boat B?
Answers
Answer: Boat A should travel 152.8° to reach B
Step-by-step explanation:
The diagram illustrating the scenario is shown in the attached photo. Triangle ABP is formed. A represents the position of boat A. B represents the position of boat B. P represents the position of the port.
We would determine AB by applying the law of cosines
AB² = AP² + BP² - 2AP×BPCosP
AB² = 20² + 25² - 2 × 20 × 25 × Cos45
AB² = 1025 - 707.10678 = 317.89322
AB = √317.89322 = 17.83
We would determine the bearing of B from A by finding angle A. We would apply the sine rule.
AB/SinP = AP/Sin A
17.83/Sin45 = 20/SinA
Cross multiplying, it becomes
17.83 × SinA = 20Sin45 = 14.14
SinA = 14.14/17.83 = 0.79
A = Sin^-1(0.79) = 52.2°
The total angle at A is 65 + 52.2 = 117.2°
The angle formed outside the third quadrant is 117.2 - 90 = 27.2°
Therefore, bearing B from A is
180 - 27/2 = 152.8°
