Answers
Answer:
Answer is both covered same level of brightness
sorry for bad handwriting
Both candles covered the same space by the light per candle.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Nayeli light a 4m² space with 12 candles. The space covered by the light per candle is calculated as,
⇒ 4/12
⇒ 0.3333 m² per candle
Citlali lights a 10m² space with 30 of the same type of candles. The space covered by the light per candle is calculated as,
⇒ 10/30
⇒ 0.3333 m² per candle

SA = 244.92² inches
Step-by-step explanation:
Basically just plug in the information given to you into the equation.
π (pi) = 3.14
r (radius) = 3 (radius is 1/2 of diameter, and the diameter is 6; half of 6 is 3 so that is the radius)
h (height) = 10
Therefore your equation set up should look like:
2(3.14)(3²) + 2(3.14)(3)(10) = 244.92

A map of a town has no scale. You know that the distance between the post office and the park is 2 mi. On the map it is 2 in. Also, on the map you know the distance from the park to the school is 8 in. What is the actual distance in miles between the park and the school?
A. 0.5 mi.
B. 4 mi.
C. 8 mi.
D. 16 mi.
Answers
If you are given a 2 inch distance from the post office to the park and it’s known that 2 inches= 2 miles and you also know that the distance from the park to the school is 8 inches which is 4 times more than the distance from the post office to the park then you know that the amount of miles will be 4 times more than 2 miles so, 4x2=8 which means that the distance between the park and school is 8 miles.

write an equation using x and y to represent the hanger.
Answers
Answer:
Step-by-step explanation:
Givens
The triangle is x
The square is y
Left side
x + 3y is the weight
Right side
4x + y is the weight.
The weights are equal because the hanger is balanced.
Balance equation
x + 3y = 4x + y Subtract x from both sides
x-x + 3y = 4x-x + y Combine
3y = 3x + y Subtract y from both sides
3y - y = 3x + y - y Combine
2y = 3x
Answer
2y = 3x
Answer:
x +3y = 4x +y
Step-by-step explanation:
A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.
__
left sideThe left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...
x + 3y
right sideThe four triangles and 1 square on the right can have their total weight represented as ...
4x +y
balanceThe intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...
x +3y = 4x +y
_____
Additional comment
This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:
x +2y = 4x . . . . subtract y from both sides
2y = 3x . . . . . . . subtract x from both sides
y = (3/2)x . . . . . divide by the coefficient of y
This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

Answer: 108 ft³
Step-by-step explanation:
V= 4/3πr³
Facts:
Pi= 3
Diameter = 6
Step1; find the radius
Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.
1/2 of 6= 1/2x6= 3.
R= 3
Step 2: Plug in the numbers (into the formula)
PEMDAS
(exponents go first)
(then multiply from left to right)
V= 4/3πr³
V= 4/3x3x3³
V= 4/3x3x (3x3x3)
V= 4/3x3x27
V= (4/3x3) x 27
V= 12/3x27
V= 4x27

A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.
Answers
Answer:
75 total tickets
Step-by-step explanation:
METHOD 1:
We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.
So, basically, we solve for x:
We have, 60% × x = 45
or, 60/100 × x = 45
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 45 × 100/60
x = 75
If using calculator, enter 45x100/60, which will give you the answer.
------------------------
METHOD 2:
Division is the opposite of multiplication
Start with the formula to calculate the percentage of total
y=value÷ percentage/100
Substitute values in the equation
y=45÷60/100
Simplify and solve
y=45÷0.6
y=75
Both methods give you 75, therefore 75 tickets have been sold

Let x, and x+1 be the consecutive numbers.
[tex]x + (x + 1) = 37[/tex]
[tex]2x + 1 = 37[/tex]
[tex]2x = 36[/tex]
[tex]x = 18[/tex]
Plug in 18 for x+1,
[tex]18 + 1 = 19[/tex]
So the numbers is 18,19
Answer:
18 and 19
Step-by-step explanation:
if you have two consecutive numbers, then using algebra, one unknown number is x and the other unknown consecutive number is x + 1
The equation x + x + 1 = 37
To solve this equation subtract 1 from both sides as one does in algebra.
x + x + 1 = 37 → x + x + 1 - 1 = 37 - 1
Now you have the equation x + x = 36
This can rewrite this as 2x = 36 2x means 2 times the value of x
To solve this part of the equation divide both sides by 2
2x / 2 = 36 / 2
x = 18
The next consecutive number x + 1 = 19, (18) + 1 = 19
check this by adding. 18 + 19 = 37.

Which of the following are acute scalene triangles?
Answers
Answer:
Y and Z.
Step-by-step explanation:
My reasoning is that because scalene triangles have all different measurements, Y and Z would be correct since they have multiple different measurements. X is an obtuse triangle, while W is a right triangle, so that leaves Y and Z.
===========================================================
Explanation:
Triangle W is a right triangle because of the square marker. This angle is 90 degrees, also known as a right angle.
Acute triangles on the other hand must have all angles smaller than 90 degrees. This rules out triangle W.
The missing angle of triangle X is 180-40-35 = 105 degrees, showing this triangle is obtuse. Obtuse triangles have exactly one angle that is between 90 and 180. Therefore, we rule out triangle X as well.
Triangles Y and Z are acute because all angles are smaller than 90 degrees. For triangle Y, the missing angle is 180-70-80 = 30. For triangle Z, the missing angle is 180-65-45 = 70 degrees.
---------------
That takes care of the "acute" portion. Now onto the "scalene" part.
All four triangles shown are scalene. Why? Because all three sides are different lengths, as indicated by the different tickmarks.
However, we ruled out triangles W and X since they weren't acute.
Therefore, triangles Y and Z are both acute and scalene.Find the solution to:
