What is the measure of n?
6
24
n
m
n =
[?]
Answer:
n = 12
Step-by-step explanation:
By applying geometric mean theorem in the given right angle triangle,
[tex]\frac{AD}{BD}=\frac{BD}{DC}[/tex]
BD² = AD × DC
Now substitute the values of each side given,
n² = 6 × 24
n² = 144
n = 12

Wall-E is sending signals that he is driving into a crater at an angle of depression of 58°. If Wall-E covers a horizontal distance of 130 meters, what vertical distance has it traveled?
Answer:
208 meters
Step-by-step explanation:
Wall-E is sending signals that he is driving into a crater at an angle of depression of 58°. If Wall-E covers a horizontal distance of 130 meters, what vertical distance has it traveled?
tan θ = Opposite/Adjacent
θ = Angle of depression
Adjacent = Horizontal distance = 130 meters
Opposite = Vertical distance = x
θ = 58°
tan 58 = x/130 meters
Cross Multiply
x = tan 58 × 130 meters
x = 208.04348878 meters
Approximately = 208 meters
Therefore, the vertical distance it travelled is 208 meters
Philip made $1,155 in 15 days. Let "m" represent the amount of money that Philp made each day. If Philip made the same amount of money each day, how much did he make in one day.
Answer:
he made in one day is $77
Step-by-step explanation:
Given that
Philip made $1,155 in 15 days
Now based on the above information
The amount he make in one day is shown below:
= $1,155 ÷ 15 days
= $77
hence he made in one day is $77
The same would be relevant

1. Complete these statements. Give an example and solution of each.
Whenever you divide two terms with the same base, you ______ the base and _______ the exponents.
Example:
Whenever you multiply two terms with the same base, you _________ the base and ___________ the exponents.
Example:
Answer:
Whenever you divide two terms with the same base, you keep the base and subtract the exponents.
Example:
x³ / x⁷ = x³⁻⁷ = x⁻⁴ = 1 / x⁴
or
8¹³ / 8⁶ = 8¹³⁻⁶ = 8⁷
Whenever you multiply two terms with the same base, you keep the base and add the exponents.
Example:
x³ × x⁷ = x³⁺⁷ = x¹⁰
or
12⁻⁵ × 12⁹ = 12⁻⁵⁺⁹ = 12⁹⁻⁵ = 12⁴
Write an equation of the line that passes through (-4 , 2) and is parallel to the line
y = 1/4 + 1
SOLVE MY QUESTION PLEASE!!
I’LL PUT YOU IN BRAINLEST!!
Answer:
y=1/4x + 3
Step-by-step explanation:
We know that the beginning of the equation has to be 1/4x since the line has to be parallel. So what I did was start at -4,2 then go up 1 and over 4, which led me to 3 as the y intercept.

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?
Answer:
Step-by-step explanation:
Let the number of ounces of
A = x
B = y
A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?
Our system of equations is given as
x + y = 90.... Equation 1
x = 90 - y
40% × x + 55% × y = 45% × 90 ounces
0.4x + 0.55y = 40.5....Equation 2
We substitute 90 - y for x in Equation 2

21 years ago Alvin was 11 times older than Tomio. The sum of their present age is 54.
Answer:
Not sure exactly what answer you are looking for. But I assume it is the ages of them. Their original ages would be Tomio - 1 year old, Alvin - 11 years old. Now, Tomio - 22, Alvin - 32
Step-by-step explanation:
1(tomio) x 11 = 11 (alvin) (add 21 to these)
22+32=54

Determine if two triangles are congruent. If they are, state how you know.
A: Not enough information.
B: SSS
C: SAS
D: AAS
help me ASAP please!
Answer:
B. SSS
Step-by-step explanation:
The two triangles already have 2 congruent sides, and the only missing thing to see is that they both share the same side with one another. This automatically makes them congruent.
Find the missing number in the proportion.
23 over 50 = ___ over 100
Answer:
46
Step-by-step explanation:
let that number x
so [tex]\frac{23}{50} =\frac{x}{100}[/tex]
I do cross multiplication so 23*100=2300 and 50*x=50x
so 50x=2300 divide both by 50
x=46
Answer:
46
Step-by-step explanation:
since 100 is 50×2 you just do the same thing to 23 and multiply it by 2.

metropolis gets 5.8 inches of rain in october, 4.2 inches in novemeber how much does it get in december
Answer:
2.6
Step-by-step explanation:
Metropolis gets 5.8 inches of rain in October
4.2 inches of rain is seen in November
Therefore the amount that would be seen in December can be calculated as follows
= 5.8-4.2
= 1.6
4.2-1.6
= 2.6
Hence 2.6 inches of rain would be seen in December
