Answer:
x = 36°
Step-by-step explanation:
Sum of angles = 180°
66°+78°+x = 180°
144°+x = 180°
x = 180°-144°
x = 36°

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
Answers
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.

The expressions in the table represent the ages of Tito and Marie.
Person Age (years)
Tito 5x+2
Marie 4x−1
How much older is Tito than Marie? Write the expression in simplified form.

Answers
Explanation:-
Since Tito is older than Marie you have to subtract both the expressions
5x + 2 - 4x - 1
5x - 4x +2 - 1
x + 1
So that’s how you find an expression for how much older is Tito than Marie

3. What is the main question?
4. What is the answer to the main question? Show your work.
Answers
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.
This problem stuck out as one of the hardest I've ever had.
C=5/9(F-32)
I'm only 14, so this is hard for me.
Answers
Distribute the 5/9
C= 5/9F - (5/9)(32)
C = 5/9F - 17.78
That is the final answer for C. To find F, do this:
C = 5/9F - 17.78
Add 17.78 to both sides
C + 17.78 = 5/9F
Multiply both sides by 9/5 to cancel out the fraction on the left side
9/5C + (9/5)(17.78) = F
F= 9/5C + 32

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 .

What is the area of the rectangle?
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
The area of the rectangle is calculated by the formula below:-
Area = Length x Width
Area = 4⁴/₄ x 7⁵/₆
Area = (18 / 4) x ( 47 / 6 )
Area = 141 / 4
Area = 35⁵/₂₄ square meters
Therefore, the area of the rectangle will be 35⁵/₂₄ square meters.

What is the perimeter of a right triangle if the hypotenuse is 15 centimeters and one of the legs is 9 centimeters?
Answers
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: x = 31

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

he hidden question is what the temperature was four days prior to the record high temperature of 39°C.
To find the temperature four days earlier, subtract 14.2°C from the record high temperature of 39°C:
39°C - 14.2°C = 24.8°C
The main question is how much higher the record temperature was than the high temperature four days earlier.
To find the answer, subtract the temperature four days earlier (24.8°C) from the record high temperature (39°C):
39°C - 24.8°C = 14.2°C.
So, the record temperature was 14.2°C higher than the high temperature four days earlier.
