Find the value of y that makes 120y a perfect square
Step-by-step explanation:
y = 30
120y = 120×30 = 3600
√3600 = 60
The value of y is 60 which makes 120y a perfect square.
What is a perfect square?A perfect square is a number that represents the square of a natural number.
For example 9,16,36,64,121 etc
Here given that we have to calculate the value of y for which 120y will be a perfect square.
so 120y = n² where n is the natural number
For calculating the value of y first factorize 120
120= 2*2*2*3*5
= 2² * 2*3*5
=4 *30
from the above, it is clear that 120 can be written as 4*30 where 4 is a perfect square but 30 is not a perfect square.
So if we multiply 30 by 120 then the product has 2²*30² which will be a perfect square.
Therefore the value of y is 30 for which 120*30=n² where n=60.

A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the observation tower's shadow? Write your answer as a whole number or a decimal. Do not round.
Answer: 9 yards
Step-by-step explanation:
Given
The maple tree is 16 yards tall and its shadow is 12 yards tall
Suppose the angle made by the maple tree is x
[tex]\Rightarrow \cos x=\dfrac{12}{16}[/tex]
For the tower also, the angle made by the tower and its shadow is x
Suppose the length of the shadow is y
[tex]\Rightarrow \cos x=\dfrac{y}{12}[/tex]
Substitute the value of [tex]\cos x[/tex]
[tex]\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}[/tex]

Have a great rest of your day!Dos libras de carne de res y dos de chivo cuestan $334 pesos, si duplico la libra de carne de res y una libra de chivo cuestan $420 pesos. ¿Cuál es el precio por libra de cada producto?
Answer:
El precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.
Step-by-step explanation:
Con la información proporcionada puedes escribir las siguientes ecuaciones:
2x+2y=334 (1)
4x+y=420 (2), donde:
x es el precio por libra de carne de res
y es el precio por libra de chivo
Primero, puedes despejar x en (1):
2x=334-2y
x=334/2-2y/2
x=167-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
4(167-y)+y=420
668-4y+y=420
668-3y=420
668-420=3y
248=3y
y=248/3
y=82.67
Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:
x=167-y
x=167-82.67
x=84.33
De acuerdo a esto, la respuesta es que el precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.
easy algebra question below first correct answer gets brainliest
Answer:
10
Step-by-step explanation:
We solve using Pythagoras Theorem. Pythagoras Theorem is used to solve for the missing side of a right angled triangle.
The formula for Pythagoras Theorem =
c² = a² + b²
c = √a² + b²
Where c is the longest side
From the above diagram, we are looking for c
c = ?
a = 6
b = 8
Hence,
c = √6² + 8²
c = √36 + 64
c = √100
c = 10
Therefore, side c = 10
10 people take 8 days to build a wall.
How long will it take 4 people to do the same job?
Answer:
20 days
Step-by-step explanation:
10 to get to 4 needs to be divided by 2.5 so we do the opposite to the other side since with fewer people it would take longer. (2.5 times longer).
10/2.5 = 4
8x2.5 = 20 days

Answer:
x²-7x+12
Step-by-step explanation:
When doing these types of problems, you have to multiply each term with each other.
Lets take a look at this.
We have to multiply each term with each other, so x times x =x²
x times -3=-3x
x times -4=-4x
-3 times -4=12
now we add them all up to get
x²-7x+12
Question 4
At practice, Diego does twice as many push-ups as
Noah, and also 40 jumping jacks. He does 62 exercises
in total. The equation 2x+40=62 describes this situation.
What does the variable x represent?
The number of push-ups Diego does.
The number of push-ups Noah does.
The number of jumping jacks Diego does.
The number of jumping jacks Noah does.
Answer: The number of push-ups Noah does.
Step-by-step explanation:
Diego does twice as many push-ups as
Noah (2x) and also 40 jumping jacks (+40). He does 62 exercises (=62).
It's not the amount that Diego does because Diego's amount is twice of Noah's, or twice of x. X would have to equal the number of push-ups Noah does.

Answer:
a=55
b=55
c=125
d=125
e=55
f=55
g=125
Step-by-step explanation:
Answer:
∠a = 55°, ∠b = 55°, ∠c = 125°, ∠d = 125°, ∠e = 55°, ∠f = 55°, ∠g = 125°
Step-by-step explanation:
straight lines form 180°:
125° + ∠a = 180°
=> ∠a = 55°
verticle angles are congruent:
∠c = 125°
∠b ≅ ∠a => ∠b = 55°
When two line are parallel:
same side interior angles are congruent:
∠g ≅ ∠c => ∠g = 125°
∠e ≅ ∠a => ∠e = 55°
∠d = 125°
∠ f ≅ ∠b => ∠f = 55°

Answer: Peter had the fastest interval at D.
Step-by-step explanation:
Peter traveled roughly 180 miles in 3 hours for point D, thus making him the fastest.
Peter had the fastest interval at D.
What is speed ?Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
From Point A to Point B Peter traveled roughly 30 miles in 30 minutes.
From Point B to Point C Peter traveled roughly 130 miles in 2 hours and 30 minutes.
From Point C he didn't move in distance but the hours moved so c is out.
From Point C to Point D, Peter traveled roughly 180 miles in 3 hours.

rene completed a 10 mile run in 1 hour and 20 minutes. Which calculation would give her average speed (mph)
Answer:
7.5 mph
Step-by-step explanation:
Given :
Distance traveled in miles = 10 miles
Time taken = 1 hour 20 minutes
In other to express average speed on terms of miles per hour :
Time in hour = 80 / 60 = 1.333333 hours
Average speed = Distance traveled / time taken
Distance = 10 miles / 1.33333 hours
Distance = 7.5 miles per hour
