The polygons are similar, but not necessarily drawn to scale. Find the value of x.
question 3/4
Answers
Answer:
i am having trouble with that too
Step-by-step explanation:
Answer:
Since we are told that the two given polygons are said to similar, their corresponding side lengths are proportional to each other.
so to solve
(x - 3)/2.5 = 16/4
(x - 3)/2.5 = 4
Multiply both sides by 2.5
x - 3 = 4 × 2.5
x - 3 = 10
Add 3 to both sides
x = 10 + 3
x = 13
So the value of x is 13.

Take a factor out of the square root:
Answers
Answer:
[tex]-y\sqrt{3}[/tex]
Step-by-step explanation:
Under the radical there is a perfect square, one can take the perfect square out, and write it by its square root. The result of taking the principal square root is always positive, but it is given that the perfect square factor is negative, thus, one must multiply the square root by the negative sign to ensure that the result is positive.

60 tickets to a concert was sold. Adult tickets cost $5 while children’s tickets cost $3.50. A total of $250 was collected. How many adult and children tickets were sold?
Answers
Answer:
Number of adults tickets sold = x
= 26.67 tickets
Number of children tickets sold = y = 33.33 tickets
Step-by-step explanation:
Let
Number of adults tickets sold = x
Number of children tickets sold = y
x + y = 60 (1)
5x + 3.50y = 250 (2)
From (1)
x = 60 - y
Substitute x = 60 - y into (2)
5x + 3.50y = 250
5(60 - y) + 3.50y = 250
300 - 5y + 3.50y = 250
- 5y + 3.50y = 250 - 300
- 1.50y = 50
y = -50/-1.50
y = 33.33
Substitute y = 33.33 into 1
x + y = 60
x + 33.33 = 60
x = 60 - 33.33
x = 26.67 tickets
Number of adults tickets sold = x
= 26.67 tickets
Number of children tickets sold = y = 33.33 tickets
Write the equation of the line in slope-intercept form passing through the points (-4,2) and (1,12)
Answers
Answer:
y = 2x + 10
Step-by-step explanation:
Find the slope:
12 - 2 / 1 - (-4)
10 / 5 = 2
Write in point-slope form:
y - 12 = 2(x - 1)
rearrange:
y - 12 = 2x - 2
y = 2x + 10

Two number cubes are rolled.
What is the probability that the first lands on an odd number and the second lands on an even number?
Enter you answer, as a fraction in simplified form, in the box
Answers
Answer:
1/4
Step-by-step explanation:
Assuming the number cube is a six-faced die, you have
1 2 3 4 5 6
three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. That means you have a 50% chance to get an odd number, or an even number.
So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?
You would have a 25% chance for an even and then an even numberYou would have a 25% chance for an odd and then an odd numberYou would have a 25% chance for an even and then an odd numberYou would have a 25% chance for an odd and then an even number.25% as a simplified fraction is 1/4. Therefore, 1/4 is your answer.

What is the vertex of the following quadratic equation?
y = 7(x + 5)2 + 4
A. (5,4)
B. (-4,5)
C.(-5, 4)
D. (7,-4)
Answers
Answer:
C.(-5, 4)
Step-by-step explanation:
The vertex form of a parabola of this type is:
y = a ( x − h ) 2 + k [1]
where ( h , k ) is the vertex.
Explanation:
Given:
y = 7 ( x + 5 )² + 4 [2]
We can convert equation [2] into the same form as equation [1] by writing
+5 as − − 5 :
y = 7 ( x − − 5) ² + 4 [3]
We observe that the vertex is
( − 5 , 4 )

Find M<1, M<2, M<3, M<4, M<5
Answers
Answer:
Step-by-step explanation:
m∠2 = 52° [Alternate interior angles]
m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]
m∠1 = 180° - 52°
m∠1 = 128°
m∠3 = 47° [Alternate interior angles]
m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]
m∠5 = 180° - 99°
= 81°
m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]
m∠4 = 180° - 47°
m∠4 = 137°
You want to frost a 13 in. by 9 in. cake that you just baked when you notice your little brother ate a piece right out of the middle. What area of cake is left to be frosted if he ate a 2 in. by 2 in. piece? no links pls :) thanks will give brainliest
Answers
Answer:
113 inches
Step-by-step explanation:
13 times 9 is 117 inches (this is the area for the whole cake)
2 times 2 is 4 (this is just the middle)
But since the brother ate the middle you will have to subtract the area of the middle piece from the whole area.
117-4 is 113 so the area now is 113 inches

Tea bags are sold in three sizes of box. A small box of 50 tea bags costs £2.15 A medium box of 80 tea bags costs £3.29 A large box of 125 tea bags costs £5.17 Which size of box is the best value for money?
Answers
Answer:
medium box
Step-by-step explanation:
The computation is shown below:
For small box,
= £2.15 ÷ 50
= £0.043
For medium box
= £3.29 ÷ 80
= £0.041125
And, for large box
= £5.17 ÷ 125
= 0.04136
So as per the above calculation the medium box should represent the best value for the money
