Answer: Yes. The data provides convincing evidence.
Step-by-step explanation:
In a random sample of 40 teenagers, 18 enjoy reading for fun. The percentage of teenagers who enjoy reading for fun will be:
= 18/40 × 100
= 45%
In a random sample of 40 adults, 12 enjoy reading for fun. The percentage of adults who enjoy will be:
= 12/40 × 100
= 30%
Therefore, the proportion of adults who enjoy reading for fun is less than that of teenagers. Therefore, the data provides convincing evidence.

You have some candies in your pocket. A friend gives you five more candies. When you count all your candies you have 14
Answer:
9 candies
Step-by-step explanation:
You are required to find the number of candies in your pocket
Let
x = number of candies in your pocket
A friend gives you five more candies.
Total candies = 14
This can be represented by the equation:
Total candies = candies in your pocket + candies your friend gave you
14 = x + 5
14 - 5 = x
9 = x
x = 9 candies
x = number of candies in your pocket = 9

Answer:
150 degrees
Step-by-step explanation:
I think V and T add up to 180 degrees (and all angles in a whole quadrilateral add up to 360) so if you add them and make it equal 180 you can solve x.
So x + 3x + 60 = 180
4x = 120
x = 30 degrees
So V is 3(30) + 60 = 150 degrees

10.
Which explanation provides the best real-world scenario of the graph?
A. If an object is dropped from a height of 38 feet, the function h(t) = –16t2 – 38 gives the height of the object after t seconds.
B. If an object is dropped from a height of 38 feet, the function h(t) = –16t2 + 38 gives the height of the object after t seconds.
C. If an object is dropped from a height of –16 feet, the function h(t) = –16t2 + 38 gives the height of the object after t seconds.
Answer:
B. If an object is dropped from a height of 38 feet, the function h(t) = –16t2 + 38 gives the height of the object after t seconds.
Step-by-step explanation:
The equation that models the movement of the object is:
Where,
t: time
a: acceleration due to gravity
v0: initial speed
h0: initial height
Suppose that the object falls with zero initial velocity and from a height of 38 feet.
The equation that models the problem is:
Answer:
If an object is dropped from a height of 38 feet, the function h (t) = -16t2 + 38 gives the height of the object after seconds
Answer: If an object is dropped from a height of 38 feet, the function h (t) = -16t2 + 38 gives the height of the object after seconds

Find the area and round to the nearest tenth. Giving brainlessly
Answer:
38.6 sq ft
Step-by-step explanation:
This composite figure consists of a trapezoid and a triangle on top
A(trapezoid) = 1/2h(sum of bases)
= 1/2(3.6)(7+9)
= 8(3.6)
= 28.8
A(triangle) = 1/2bh
base = 7
height = 6.4-3.6 which is 2.8
A = 1/2(7)(2.8)
= 3.5(2.8)
= 9.8
28.8 + 9.8 = 38.6

Solve the equation 3(+4.5)=36
What is the value of x?
Answer:
x=7+1/2
Step-by-step explanation:
We move all terms to the left:
3(x+4.5)-(36.)=0
We add all the numbers together, and all the variables
3(x+4.5)-36=0
We multiply parentheses
3x+13.5-36=0
We add all the numbers together, and all the variables
3x-22.5=0
We move all terms containing x to the left, all other terms to the right
3x=22.5
x=22.5/3
x=7+1/2

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Define
Identify and set up
6x° + 36° + 108° = 180°
Step 2: Solve for x
[Addition] Combine like terms: 6x° + 144° = 180°[Subtraction Property of Equality] Subtract 144° on both sides: 6x° = 36°[Division Property of Equality] Divide 6 on both sides: x = 6Answer:

someone help please I'm having a hard time understanding
Answer:
the angle shown is a straight angle value of which is equal to 180°
3x + 30. 6 = 180
3x = 180 - 30. 6
3x = 149.4
x = 49.8ANSWER

Answer:
7. x = 38°
8. y = 65°
9. 261° and 81°
Step-by-step explanation:
Finding x:
You can make an equality with (2x +5) and (3x +33) because the value of these angles are the same, so:
2x +5 = 3x -33
2x - 3x = -33 -5
-x = -38
x = 38°
Finding y:
You can find the value of y making another equally, but this time you have to sum (4y -1) with (3x - 33) or (2x +5) and equal it with 180°:
(4y -1)+(2x +5) = 180
4y -1 +2x +5 = 180
4y +2x +4 = 180
We know from the question 7 that x is 38°:
4y +2•(38) +4 = 180
4y - 76 +4 = 180
4y - 80 = 180
4y = 180 + 80
4y = 260
y = 260/4
y = 65
Finding the value of the angles:
You just have to put the value of x and y in their places and make the calculations:
4•65 +1 = 261°
3•(38) -33 = 81°

have a good day :)
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
36/54 = 2*18 /2*27 = 18/27 yet can be reduced further
18/27 = 3*6/3*9 = 6/9 we are not done

Which of the following is/are cube(s) of even number (i) 249 (ii) 50653
Answer:
None (If there are just these two options i.e, 249 and 50653. I think there are more options, anyway)
Step-by-step explanation:
Cubes of even numbers are even and cube of odd numbers are odd.
Since both the numbers are odd, both of their cubes must be odd too.

How do you find the area of a triangle? Is it base x height divided by 2???
Answer:
yes The area of a triangle is b x h / 2 (base times height divided by 2)
Hi there!
»»————- ★ ————-««
I believe your answer is:
[tex]\boxed{\frac{b*h}{2}}[/tex]
You should be correct.
»»————- ★ ————-««
Here’s why:
The given formula for a triangle is similar to the formula for area of a square or rectangle. A triangle is basically a 'half-rectangle'.⸻⸻⸻⸻
[tex]\boxed{\text{Area of a triangle:}}\\\\A = \frac{b*h}{2}\\\\\boxed{\text{Key:}}\\\\\rightarrow \text{B - Base}\\\\\rightarrow \text{H - Height}[/tex]
⸻⸻⸻⸻
The area of a triangle is the half the product of the base and height of the triangle.⸻⸻⸻⸻
