Step-by-step explanation: Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Answer: 32
Step-by-step explanation:
Here, (3x-4) and (3x-8) make up to 180
So,
3x - 4 + 3x - 8 = 180
6x -12 = 180
6x = 192
x = 32

In the diagram below, what are AC and BC?
Answer:
AC = 5 +5√3 ≈ 13.66
BC = 5√2 ≈ 7.07
Step-by-step explanation:
You want the measures of sides AC and BC in ∆ABC with AB=10, A=30°, C=45°.
Special trianglesDrawing altitude BD divides the given triangle into two "special" right triangles:
∆ABD with side lengths BD : AD : AB = 1 : √3 : 2∆CBD with side lengths BD : CD : BC = 1 : 1 : √2Using these ratios, we find ...
BD = AB/2 = 10/2 = 5
AD = BD√3 = 5√3
CD = BD = 5
BC = BD√2 = 5√2
Then ...
AC = AD +CD = 5√3 +5
The side measures are AC = 5+5√3 ≈ 13.66, and BC = 5√2 ≈ 7.07.

Answer: x = 31
Step-by-step explanation:
(5x - 16) + (x + 10) = 180
6x - 6 = 180
6x = 186
x = 31
Answer: 31
Step-by-step explanation:
Here,
(5x-16) and (x+10) angles make up to 180. So,
5x - 16 + x + 10 = 180
6x -6 = 180
6x = 180 + 6
6x = 186
x = 186/6
x = 31
Hence, x = 31

What is the perimeter of a right triangle if the hypotenuse is 15 centimeters and one of the legs is 9 centimeters?
Answer:
The perimeter of a triangle is the sum of the lengths of all its sides. In a right triangle, the length of the hypotenuse is the longest side, and the other two sides are called legs.
Given that the hypotenuse is 15 centimeters and one of the legs is 9 centimeters, we can use the Pythagorean theorem to find the length of the other leg. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Therefore, we can write the equation:
c^2 = a^2 + b^2
where c is the length of the hypotenuse and a and b are the lengths of the legs. Substituting the given values, we get:
15^2 = a^2 + 9^2
225 = a^2 + 81
144 = a^2
a = 12
So, the length of the other leg is 12 centimeters. The perimeter of the triangle is the sum of the lengths of the three sides, which is 15 + 9 + 12 = 36 centimeters.
Answer:
36 cm
Step-by-step explanation:
First, we have to find the length of the other leg using the Pythagorean theorem.
For that, let the length of the missing leg be x.
Let us find it now.
x² + 9² = 15²
x² + 81 = 225
Subtract 81 from both sides.
x² = 225 - 81
x² = 144
x = √144
x = 12 cm
So, the length of the missing side is 12 cm.
Now, let us find the perimeter of the triangle.
For that, you can simply add the lengths of three sides.
P = 15 + 9 + 12
= 36 cm

Answer:
y + 10x - 62 = 0
Step-by-step explanation:
Let the linear relation between the two variables be given by y=mx + c
Now we put the values to get the constants.
58 = 2m + c
52 = 5m + c
solving we get :
52 - 5m = 58 - 2m
or, -6 = 3m
or, m = -2
Now we put those values in the equations
52 = 5m + c
or, 52 = -10 + c
or, c = 62
The equation relating the sunglasses is y + 10x - 62 = 0 .
Jessie has some marbles. The number of marbles he has is more than 50 but less than
100. When the marbles are placed in groups of 10, there is a remainder of 3 and when
they are placed in groups of 6, there is a remainder of 1.
How many marbles does Jessie have?
Answer:
59 marbles.
Step-by-step explanation:
Let's call the number of marbles Jessie has "x".
We know that:
x > 50
x < 100
x % 10 = 3
x % 6 = 1
We can start by finding the possible values of x that satisfy both x % 10 = 3 and x % 6 = 1.
Starting from x = 53:
x = 53 satisfies x % 10 = 3 but not x % 6 = 1
x = 59 satisfies both x % 10 = 3 and x % 6 = 1
So, Jessie has 59 marbles.
(15m + 20p) + 25q = 15m + (20p + 25q)

so you have a lateral surface area of 108
add in the triangle pieces that are 3cm on each side and the triangle rule is 1/2 so it would be 6 on each "wing"
so you would have 27+36+45+12 = 120cm2

Estimate the total surface area of the Triangular prism represented by the net below
Answer:
Step-by-step explanation:
it would be c. 116
This is because each rectangle has an area of 36 and there are 3 which equals 108
Also each triangle has an area of 3.9 and there are two so it is 7.8 for both of the triangles
108+15.6 is 115.8
That is approximately 116
That is why its 116
a florist was asked to make a flower arrangement that contains at most 36 roses. the florist has already used 17 roses in the arrangement. which inequality represents all the possible numbers of roses, r, that the florist can still add to the arrangement
Answer:
r + 17 ≤ 36
Step-by-step explanation:
The inequality that represents all the possible numbers of roses that the florist can still add to the arrangement is:
r + 17 ≤ 36
This means that the total number of roses, including the 17 that have already been used, must be less than or equal to 36. The variable "r" represents the number of additional roses that the florist can add to the arrangement.

so the angle across 4x is her twin, and 3x + x = 4x.
Find the value of x.
Answer:
x = 36°
Step-by-step explanation:
Sum of angles = 180°
66°+78°+x = 180°
144°+x = 180°
x = 180°-144°
x = 36°

he average high temperature in July in Moscow is 23°C. One day in July 2010,
the temperature was 14.2° higher than normal. Just four days later, a record high
temperature of 39°C was set. How much higher was the record temperature than the
high temperature four days earlier?
1. What is the hidden question?
2. What is the answer to the hidden question? Show your work.
3. What is the main question?
4. What is the answer to the main question? Show your work.
Answer:
Below
⬇️
Step-by-step explanation:
1. The hidden question is "What was the high temperature four days earlier?"
2. To find the high temperature four days earlier, we need to subtract 14.2 from the record high temperature of 39°C:
39 - 14.2 = 24.8°C
3. The main question is "How much higher was the record temperature than the high temperature four days earlier?"
4. To find the difference between the record temperature and the high temperature four days earlier, we need to subtract 24.8 from 39:
39 - 24.8 = 14.2°C
So, the record temperature was 14.2°C higher than the high temperature four days earlier.
