A right triangle has legs that are 15 feet and 25 feet long.
What is the length of the hypotenuse?
Answers
15^2 + 25^2 = X62
225 + 625 = x^2
850 = x^2
x = 5sqrt(34)
if you need it as a decimal = 29.1547
Answer: The length of the hypotenuse is 5√34 units.
Step-by-step explanation: Given that a right-angled triangle has legs of length 15 ft and 25 ft.
We are to find the length of the hypotenuse.
As shown in the attached figure, AB and BC are the legs of the right-angled triangle ABC. AC is the hypotenuse of the triangle.
Also, AB = 15 ft and BC = 25 ft.
From Pythagoras theorem, we have
[tex]AC^2=AB^2+BC^2\\\\\Rightarrow AC^2=(15)^2+(25)^2\\\\\Rightarrow AC^2=225+625\\\\\Rightarrow AC^2=850\\\\\Rightarrow AC=\sqrt{850}\\\\\Rightarrow AC=5\sqrt{34}.[/tex]
Thus, the length of the hypotenuse is 5√34 units.

what is the domain of the function y=3sqrt(x)
Answers
x≥0
Because every number in the domain must yield real number outputs, set what is in the radical greater than or equal to 0.
The domain of the function
[tex]y = 3 \sqrt{x} [/tex]
is
[tex]x \geqslant 0[/tex]
EXPLANATION
The domain of a function refers to all values of x for which y is defined.
Since this is a square root function, we need to keep the expression under the square root sign to be greater than or equal to zero.
As soon as the expression under the root sign is less than zero, the function will not be defined.
This means that the square root of a negative number will not be a real number.
Thus the domain is
[tex]x \geqslant 0[/tex]

Choose the right answer. If the distance on a map from point R to point T measures 3.0 inches and the scale is 1 inch = 0.5 miles, what is the distance in miles from point R to point T? ______ miles
A. 6.0
B. 3.0
C. 1.5
Answers
Answer: The distance from point R to point T is 1.5 miles.
Step-by-step explanation:
In the map, the scale is,
1 inches = 0.5 miles,
3 inches = 3 × 0.5 = 1.5 miles,
Thus, in the map 3 inches shows 1.5 miles,
Since, in the map, the distance from point R to point P = 3 inches,
Thus, the actual distance from point R to point P = 1.5 miles.

m∠3 = 180 - 126.5 - 19 = 34.5°
6
m∠3 = 180 - 65.5 - 85 = 29.5°
7
m∠3 = 180 - 98.3 - 37.5 = 44.2°
8
m∠3 = 180 - 31 - 113 = 36°
So all we have to do is subtract the 2 angles we know from 180:
For question 5, we subtract 126.5° and 19° from 180°:
180 - 126.5 - 19 = 34.5°
The same principle applies for the rest.
Question 6:
180 - 65.5 -85 = 29.5°
Question 7:

What is 0.673 rounded to the nearest hundredths
Answers
Hope this helps
0.673 rounded to the nearest hundredth as 0.67
The digit in the smallest location is unaffected if it is less than 5 in number. Rounding down is the process of reducing a number to zero after a certain number of digits. The digit in the smallest location is added with +1 if it is bigger than or equal to 5.
To round off 0.673 to the nearest hundredth means hundredth digit after decimal, To do so take a look on the thousandth digit after decimal, If it is greater than 5 or equal to 5 increase the hundredth digit after decimal by 1 otherwise no change,
Here, the thousandth digit is 3, 3<5. So, no increment is required.
It will remain as 0.67.
Thus, 0.673 is 0.67 after rounding off to the nearest hundredth.

Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is Upper T equals 50 plus StartFraction Upper N minus 40 Over 4 EndFractionT=50+ N−40 4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If Nequals=9898, find the temperature in degrees Fahrenheit, T.
Answers
We have then:
T = 50 + (N-40) / 4
We substitute the value of N = 98, we have then:
T = 50 + (98-40) / 4
T = 64.5 degrees Fahrenheit.
Answer:
the temperature in degrees Fahrenheit, T is:
T = 64.5 degrees Fahrenheit.
The temperature in degrees Fahrenheit, T is 68°F.
Dolbear's law states that the number of chirps per minute that a snowy tree cricket makes is related to the air temperature in degrees Fahrenheit by the following formula:
T = 50 + (N - 40)/4
where:
T is the temperature in degrees Fahrenheit
N is the number of chirps per minute
If N = 98, then the temperature is:
T = 50 + (98 - 40)/4 = 68 degrees Fahrenheit
So the answer is 68 degrees Fahrenheit.
Here is an explanation of the calculation:
We are given that N = 98 chirps per minute.
We substitute this value into the formula for Dolbear's law to get:
T = 50 + (98 - 40)/4 = 68 degrees Fahrenheit
Therefore, the temperature is 68 degrees Fahrenheit.
Here are some additional things to consider:
The number of chirps per minute that a snowy tree cricket makes is not always an accurate measure of the air temperature. The number of chirps can also be affected by other factors, such as the humidity and the time of day.
Dolbear's law is a simplified model of the relationship between the chirping rate of snowy tree crickets and the air temperature. The actual relationship is more complex and can be affected by a number of factors.

Q = (x, y) = (- 8, 3)
A reflection of the figure on the x axis is given by the following rule:
(x, y) ----> (x, -y)
Applying the transformation:
(-8, 3) ---> (- 8, -3)
Answer:
the coordinates of point Q after this reflection are
-8, -3
The new coordinates of Q are (-8, -3).
When reflecting a point across the X-axis, the X-coordinate remains unchanged, while the Y-coordinate changes its sign. From the figure attached, we find coordinates of Q are (-8,3). Therefore:
The X-coordinate of Q remains as -8.The Y-coordinate of Q changes from 3 to -3.As a result, the coordinates of point Q after reflection along the X-axis will be (-8, -3).
Therefore, the new coordinates of point Q are (-8, -3).

△ XYZ∼ △ DEF, YZ is 10 meters, XZ is 15 meters, and EF is 8 meters. What is DF?
Solution:
As, △ XYZ∼ △ DEF , so the ratio of sides of triangle is equal.
So, we have, [tex] \frac{XY}{DE} =\frac{YZ}{EF} =\frac{XZ}{DF} [/tex]
Using, [tex] \frac{YZ}{EF} =\frac{XZ}{DF} [/tex]
So, we get,[tex] \frac{10}{8} =\frac{15}{DF} [/tex]
Now, to solve for DF, we must simplify
Simplifying,[tex] \frac{10}{8} =\frac{5*2}{4*2}=\frac{15}{DF) [/tex]
[tex] \frac{5}{4} =\frac{15}{DF} [/tex]
To simplify, Let us multiply by 4*DF on both sides
[tex] \frac{5*4DF}{4} =\frac{15*4DF}{DF} [/tex]
[tex] \frac{5DF}{1} =\frac{15*4}{1} [/tex]
So, 5 DF=15*4=60
To solve for DF, let us divide by 5 on both sides
[tex] \frac{5}{5} DF=\frac{60}{5} [/tex]
[tex] \frac{1}{1} DF=\frac{12}{1} [/tex]
So, DF=12meters

D. 2/15
E. 3/10
Answers
Final answer:
The ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes is D. 2/5.
Explanation:
To find the ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes, we need to calculate the total cost of each option.
For 6 pairs of canvas shoes, the cost is $7 per pair, so the total cost is 6 x $7 = $42.
For 3 pairs of leather shoes, the cost is $35 per pair, so the total cost is 3 x $35 = $105.
Therefore, the ratio is $42 : $105, which simplifies to 2/5.

Two tons of water is pumped into a tank 15 ft. high in 5 minutes. Determine the power output of the pump.
Answers
Answer:
0.364 horsepower
Step-by-step explanation:
You want to know a pump's power output if it raises 2 tons of water 15 ft in 5 minutes.
PowerThe power is conveniently measured in horsepower. One horsepower is 33,000 ft·lb/minute.
Here, we have (2t · 2000 lb/t · 15 ft)/(5 min) = 12000 ft·lb/min
In terms of horsepower, that is ...
(12000 ft·lb/min) / (33000 ft·lb/min/hp) = 4/11 hp ≈ 0.364 hp
The power output of the pump is about 0.364 horsepower.

Additional comment
That's about 271 watts.
The distance dimensions are in feet, so we assume the tons are US short tons of 2000 lb each.

Answers
The dilation's scale factor will be 1/4.
The division method is used to divide a bunch of items into equal portions.
Division is the inverse of multiplication. For instance, dividing 20 by 2 means dividing 20 into two equal groups of ten.
Given this,
The blue figure is a magnified version of the black one.
Furthermore, the origin is the center of dilatation.
Now,
Because the blue figure is a dilatation of the black one.
Furthermore, the origin is the center of dilatation.
In this case, the length of the black figure equals 16 units.
Furthermore, the length of the blue figure equals 4 units.
