Answer:
Number of bicycles = 30
Number of skateboards = 12
Step-by-step explanation:
Let the number of bicycles = x
Let number of skateboards = y
It is given that there are total bicycles and skateboards = 42
∴ x + y = 42 ........(1)
Now a bicycle has two tires and a skateboard has four tires, this gives an equation :
2x + 4y = 108 .......(2) (Since uncle Eddie asks to order 108 tires)
Therefore, solving equation (1) and (2), we get
2(x+y=42)
2x+4y=108
2x+2y = 84
- (2x+4y = 108)
- 4 y = - 24
or 4 y = 24
or y = 12
Now substituting the value of y in equation (1),
x + 12 = 42
x = 42 -12
x = 30
So number of bicycles = x =30
And number of skateboards = y = 12
7. Find the value of x 8. find the value of y
Answer:
x = 27.8
y = 35
Step-by-step explanation:
∡D ≅ ∡A, therefore:
65 = 2y - 5
70 = 2y
y = 35
EF ≅ BC, therefore:
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8

Answer:
x=72 degrees
Step-by-step explanation:
180-108=72
it is 180 because a straight angle is 180 degrees.
then you subtract 108, which is an alternate interior angle, to get 72, which is an alternate exterior angle.
Answer:
x=72
Step-by-step explanation:
Since the whole angle is 180 you have to do 180-108 which you get 72.
Then since x and 72 are vertical angles they have to be the same so x=72

Caroline, Colin & Sarah share some money.
Caroline gets 1/9 of the money.
Colin and Sarah share the rest in the ratio 1:3.
What proportion does Sarah get?
Answer:
2 ÷ 3
Step-by-step explanation:
Let us suppose the money be 90
Since caroline gets 1 by 9 of the money i.e. 10
And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3
So, the remaining money would be
= 90 - 10
= 80
So, the sarah could get
= 80 × 3 ÷ 4 ÷ 90
= 60 ÷ 90
= 20 ÷ 30
= 2 ÷ 3

In a batch of eggs, 3% were broken. There were 18 broken eggs
How many eggs were there in the batch?
Answer: 600 eggs
Step-by-step explanation:
Let total number of eggs be x.So, 3% of x were broken and there were 18 broken eggs. We can write this as: 0.03*x =18x=18/0.03x= 600 eggs (answer).
Total number of eggs in the bags are 600.
What is Percentage?Percentage is a number or ratio that can be "expressed as a fraction of 100".
According to the question,
Percentage of broken eggs = 3%
Number of broken eggs = 3/100 = 0.03
To calculate the total number eggs,
[tex]\frac{3}{100}[/tex] (x) = 18
x = 1800/3
x = 600.
Hence, the total number of eggs in bags are 600.

What are important things to think about when justifying a conjecture?
Answer:
Step-by-step explanation:
First, we need to understand what a conjecture means, we can take a conjecture to mean the use of observed patterns or foundational knowledge about a certain phenomenon or thing to make a decision or make a logical conclusion about such thing.
Hence, when making Justification about a conjecture, we need to take into cognizance some potent things :
1.) There must be an observed pattern, relationship between the observation upon which a conjecture is to be made. As this pattern are key to our reasoning and decision.
2.) Also, our final conclusion or conjecture will be based on the pattern observed and not on some random thought.

Which histograms are approximately symmetric and bell shaped?
Answer:
B and E
Step-by-step explanation:
im pretty sure what you have is correct
The correct histograms that are approximately symmetric and bell-shaped are - histograms B, C, and E because they are symmetric and bell-shaped.
A histogram is a convenient form or graphical representation of the frequency distribution of numerical data by means of rectangles. These histograms are found in different shapes and symmetries.
Bell-shaped curve:
if a histogram resembles or looks like a “bell” by joining the interval of rectangles in a curve and has one single peak in the middle of the distribution.In the given histograms only histogram shows a bell-like curve when joining the middle point of rectangles of distribution and also present in symmetry.in the image attach approximate curves are form you can see if it is bell shape and symmetric.Thus, the correct answer is - Histograms B, C, and E.

Answer:
im pretty sure its 36%
Step-by-step explanation:
Given that lines q and m are parallel and are cut by two
different transversal lines, j and k, use angle relationships
to determine the measure of each numbered angle:
angle 1 = 180-110 = 70 degrees (linnear pair)
angle 2= 180-115 = 65 degrees (linnear pair)
angle 3 = angle 2 = 65 degrees (corresponding angles)
angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)
(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)
angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees
angle 6 = angle 7 = 45 degrees ( vertical angles)
angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)
angle 9 =angle 6 = 45 degrees (corresponding angles)
angle 5=angle 9=45 degrees (vertical angles)

Answer:
Step-by-step explanation:
Remark
This is a Pythagorean Problem
Formula
a^2 + b^2 = c^2
a = 5
b = ?
c = 9
Solution
5^2 + b^2 = 9^2 Expand the givens
25 + b^2 = 81 Subtract 25 from both sides
25-25+b^2 = 81- 25
b^2 = 56
√b^2 = √56
b = √8*7
b = √2*2*2*7
b = 2 √2*7
b = 2 √14
