Consider the triangle. Right triangle A B C. Side A C is 24 centimeters, C B is 10 centimeters, and hypotenuse A B is c. Find the length of the hypotenuse, c. The length of the hypotenuse is cm.
Answer: The length of the hypotenuse is 26 cm
Step-by-step explanation: Please refer to the attached diagram
The triangle ABC is drawn as described such that the right angle is at point C and line AB is the hypotenuse which is yet unknown.
Since we have a right angled triangle with two sides known and one unknown, we can apply the Pythagoras theorem which states that
AC² = AB² + BC² where AC is the hypotenuse and AB and BC are the other two sides
In this question the hypotenuse is AB, so we now have;
AB² = AC² + CB²
AB² 24² + 10²
AB² = 576 + 100
AB² = 676
Add the square root sign to both sides of the equation
√AB² = √676
AB = 26
Therefore the length of the hypotenuse is 26 cm
Answer:
26 cm is the answer

The New York Times newspaper publishes one issue each day during the
year. What is the Order of Magnitude for the number of issues of the New
York Times published each year?
Answer:
The Order of Magnitude for the number of issues of the New York Times published each year is 2.
Step-by-step explanation:
Given that the newspaper publishes one issue each day and the year has 365 days, then it publishes 365 issues each year.
365 can be rewritten, with scientific notation, as: 3.65*10^2, which means it has 2 orders of magnitude (it is indicated in the exponent).

A catapult is designed to launch circus performers from a raised platform. After launch, the height of the performer in feet is given by h left parenthesis t right parenthesis equals minus 16 t squared plus 80 t plus 32 where t is seconds after launch. After how many seconds is the performer exactly 100 feet above the ground? Round to the nearest tenth of a second.
Answer:
t = 1.1 sec for first time and then in
t = 3.9 sec
Step-by-step explanation:
The function for the height of the circus performers is:
[tex]h(t) = -16t^{2} +80t +32[/tex]
where t is seconds after launch
h is height in feet
For calculating after how many seconds is the performer at 100 feet above the ground, we must equal the equation to 100 and to find t:
Then,
[tex]100 = -16t^{2} +80t+32[/tex]
[tex]0 = -16t^{2}+80t -68[/tex]
[tex]t = \frac{-80\ \pm \\\sqrt{80^{2}-4(-16)(-68) } }{2(-16)}[/tex]
t = 3.9 sec
t = 1.1 sec

The ratio of bananas to apples was 2 to 3. If there where 18 bananas how many apples where there
Answer:
There were 27 apples.
Step-by-step explanation:
Set a ratio of bananas to apples like this:
bananas/apples = 2/3
Now you have 18 bananas. The number of apples is unknown, so use "a" for the number of apples.
bananas/apples = 18/a
The two ratios above are equal, so set them equal. That creates a proportion.
2/3 = 18/a
Now we solve for a by cross multiplying.
2a = 3 * 18
2a = 54
a = 27
Answer: There were 27 apples.

What is the answer for -2/5(n + 3) = 10?
Answer: n=-28
Step-by-step explanation:
Answer:
-28
Step-by-step explanation:
1) distribute "-2/5" to each term inside the parentheses:
-2/5(n+3)=10
-2/5n+-6/5=10
add "6/5" on both sides
-2/5n-6/5+6/5=10+6/5
-2/5n=50/5+6/5
-2/5n=56/5
divide both sides by "-2/5"
n=-28

(C) $532.00
(D) $1,343.75
(E) $1,400.00
Answer:
$432
Step-by-step explanation:
75(5.76)=432
The standard deviation of Y is $432 and this can be determined by using the formula of standard deviation and the given data.
Given :
A company sells concrete in batches of 5 cubic yards. The probability distribution of X, the number of cubic yards sold in a single order for concrete from this company, is shown in the table below.The expected value of the probability distribution of X is 19.25 and the standard deviation is 5.76. There is a fixed cost to deliver the concrete. The profit Y, in dollars, for a particular order can be described by (Y = 75X - 100).The formula to obtain the standard deviation is given below:
SD(Y) = SD(75X - 100)
Simplify the above expression by substituting the value of SD(X) and SD(100) in the above expression.
SD(Y) = 75SD(X) - SD(100)
SD(Y) = 75 SD(X) - 0
SD(Y) = 75 [tex]\times[/tex] 5.76
SD(Y) = $432

Answer:
The number of hours was it before Penny was 5 miles ahead of Darla is 1 hour.
Step-by-step explanation:
Given : Darla and her friend penny left their office at the same time and began traveling down the same road in the same direction. Darla traveled at a speed of 65 mph while Penny drive at 70 mph.
To find : How many hours was it before Penny was 5 miles ahead of Darla?
Solution :
The formula used - [tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]
Darla traveled at a speed of 65 mph.
Penny drive at 70 mph.

While mining, Joan found a large metal bar that weighted 40 grams. Joan was able to determine that the bar contained 35% zinc. How many grams of zinc are in the metal bar? Round you answer to the nearest whole number if necessary.
Answer:
14g zinc
Step-by-step explanation:
To get the mass of zinc in the metal bar, you can multiply the percentage of zinc by the total mass.
40g x .35 = 14g zinc
The metal bar contains 14 g zinc in the 40 grams metal bar.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: A metal bar weighs 40 grams and it contains zinc equivalent to 35%
Let the weight of the zinc contained in the metal be x
Then we have x=35/100×40
=14 grams
Hence, The metal bar contains 14 g zinc in the 40 grams metal bar.

If the distance from a plane to a radar station is 160 miles and the angle of depression is 34 degrees, find the number of ground miles from a point directly below the plane to the radar station.
Answer:
194
Step-by-step explanation:
Final answer:
To find the ground miles from a point below the plane to the radar station given the distance and angle of depression, use trigonometry to calculate the ground distance, which is approximately 107.2 miles.
Explanation:
The number of ground miles from a point directly below the plane to the radar station can be found using trigonometry. Given the distance from the plane to the radar station (160 miles) and the angle of depression (34 degrees), we can use the tangent function.
Calculate the distance on the ground using the formula: Ground distance = 160 x tan(34°).
Ground distance = 160 x tan(34°) ≈ 160 x 0.67 = 107.2 miles.
