Answer:
a = 72 mm is the answer.
Step-by-step explanation:
a = ?
b = 21 mm
c = 75 mm
According to the Pythagoras theorem
a² + b² = c²
a² + 21² = 75²
a² + 441 = 5625
a² = 5625 - 441
a² = 5184
a = 72 mm
∴ a = 72 mm is the length of the missing leg.

3/4 Ravi is as tall as Sam, Mike is as tall as 5/3 Ravi. Find the ratio of Mike's height to Sam's height.
Answers
Answer: The ratio of Mike and Sam Heights are S:M=5:4
Step-by-step explanation:
Ravi is 3/4 as tall as Sam.
Consider the equation is 3/4 *R=S
Mike is 5/3 as tall as Ravi.
Then, the equation is 5/3 *M=R
Solve the two equation to find ratio of mikes and sam height.
3/4*R=S Eq(1)
Rearranging eq (1) for R
R=4/3 *S Eq(3) made from eQ (1)
R=5/3*M Eq(2)
Comparing Eq 2 &3 equations
4/3*S=5/3*M
S/M=(5/3)*(3/4)
S/M=5/4

the probability of choosing the first chip, then the second chip.
White and not a Green
Answers
Answer:
probability = 0.07777
Step-by-step explanation:
there are 10 chips
white 1
red 4
green 2
blue 3
the probability of choosing the W chip is 1/10 or 0.10
now there are 9 chips left (the first chip was not replaced)
the probability of choosing a non-green chip is (9-2)/9 = 7/9 = 0.7777
so now I THINK you multiply the two probabilities to get the total probability
probability = 0.1 ·0.7777
probability = 0.07777 which makes sense it has to be less than 0.1
Answer:

The area of a triangle is 92 square inches. The base is 23 inches. What is the height in inches? Do not include units in your answer.
Answers
Answer:
34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?
Answer:
Step-by-step explanation:
We can use the formula for the area of a triangle, to help us find the height:
Area=12⋅b⋅h
Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:
92=12⋅23⋅h
Isolate h by multiplying both sides by 2 and dividing both sides by 23.
hh=2⋅9223=8
The height is 8 inches.

D.0.5333
Answers
Answer:
sin x = 0.4706
Step-by-step explanation:
Given that,
Height, h = 8
Base, b = 15
Let H be the hypotenuse of the triangle. Using Pythagoras theorem,
[tex]H=\sqrt{8^2+15^2} \\\\H=17[/tex]
We know that,
[tex]\sin\theta=\dfrac{h}{H}[/tex]
So,
[tex]\sinx=\dfrac{8}{17}\\\\\sin x=0.4706[/tex]

C (x + 6)^2 + (y - 1)^2 = 49

Answers
Answer:
D [tex] (x +6) ^2 +(y-1)^2 =7 [/tex]
Step-by-step explanation:
Center of the circle (h, k) = (-6, 1)
Area of the circle [tex] =\pi r^2 [/tex]
[tex] 7\pi=\pi r^2 [/tex]
[tex] \frac {7\pi}{\pi} =r^2 [/tex]
[tex]r^2=7[/tex]
[tex]r=\sqrt 7[/tex]
Radius [tex] r=\sqrt {7}[/tex]
Equation of circle in center radius form is given as:
[tex] (x - h) ^2 +(y-k) ^2 =r^2 [/tex]
Plugging the values of h, k and r in the above equation, we find:
[tex] [x - (- 6)] ^2 +[y-1 ]^2 =(\sqrt {7})^2 [/tex]
[tex] (x +6) ^2 +(y-1)^2 =7 [/tex]

A scale model of an object has a scale of 1cm : 2ft. The actual object is 11 feet tall. How tall is the model?
Answers
Given:
The scale model of an object has a scale of 1cm : 2ft.
The actual object is 11 feet tall.
To find:
The height of the model.
Solution:
It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.
Let the height of the model be x cm.
[tex]\dfrac{x\ cm}{11\ ft}=\dfrac{1\ cm}{2 \ ft}[/tex]
[tex]x\ cm=\dfrac{1 \ cm\times 11\ ft}{2 \ ft}[/tex]
[tex]x\ cm=5.5\ cm[/tex]
Therefore, the model is 5.5 cm tall.

The mean is the usual average, so add all of the numbers and then divide.
The mode is the number that is repeated more often than any other.
The range is the largest value and smallest value subtracted.
Answer:
Answer bellow
Step-by-step explanation:
To find mean(average) get all the numbers and and add them together after devide the added number by the number of numbers
