Answer:
15 bicycles
Step-by-step explanation:
ratio of bicycles to tricycles is 5:1 because it is 5 times greater and tricycle has 3 wheels and bicycles have 2 so i take 5 from the ratio and make a equation 5(2)+3(1)=13
i then divide 39 by 3 and get 3 i then take 3 and multiply it with it for the whole equation and find that 15 is the number of bicycles.

Answer:
150 degrees
Step-by-step explanation:
8x-10=3x+90
solve for x in calculater
x = 20
Substitute:
3(20)+90 = 150
Answer:
Step-by-step explanation:
8x - 10 = 3x + 90
5x - 10 = 90
5x = 100
x = 20
8(20) - 10 = 160 - 10 = 150

Answer:
Y=x
Step-by-step explanation:
it's a straight line passing by the center (0,0) at 45°
You can tell because Y is equal to X for every value of X and the points you posted fall in this case.
How can you solve for X in the proportion of7/8 equals X/24
Answer and Step-by-step explanation:
The last answer choice is correct.
Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x
The process being used in the last answer choice is called Cross multiplication, and is used to find the unknown value in fractions.
[tex]\frac{7}{8}[/tex] × [tex]\frac{x}{24}[/tex]
7 × 24 = 8x
168 = 8x
21 = x

factorise completely 15p^2 + 24pt
Answer:
3p(5p + 8t)
Step-by-step explanation:
15p^2 + 24pt
3(5p^2 + 8pt)
3p(5p + 8t)
The completely factored form of 15p^2 + 24pt is 3p(5p + 8t).
How to determine the factored formTo factorize the expression 15p^2 + 24pt using superscripts, we can follow the same steps as before.
First, let's find the GCF of the coefficients 15 and 24, which is 3:
GCF(15, 24) = 3
Next, we'll look for the GCF of the variables p^2 and pt, which is p:
GCF(p^2, pt) = p
Now, we can factor out the GCF from each term:
15p^2 + 24pt = 3p(5p + 8t)
Therefore, the completely factored form of 15p^2 + 24pt is 3p(5p + 8t).

what is the range of the function graphed below?
i honestly have no idea please help
Answer:
C
Step-by-step explanation:
The range of a graph is how far the graph goes up and down. The lower boundary is easy, as we can see that the left side of the line goes down forever, so it is negative infinity. Looking at the top of the graph, we can see that the graph never goes past y=2. So the answer is:
-∞<y<2

Which of the following statements is most likely true?
1. There is no correlation between arithmetic skills and losing baby teeth.
2. There is a correlation here, and losing baby teeth causes arithmetic skills to improve.
3. There is a correlation here, and improving arithmetic skills causes the loss of baby teeth.
4. There is a correlation here, but there is not a direct causal relationship between losing baby teeth and arithmetic skills.
There is a bag with only milk and dark chocolates. The probability of randomly choosing a dark chocolate is 3 8 . There are 21 dark chocolates in the bag and each is equally likely to be chosen. Work out how many milk chocolates there must be.
Answer:
Number of milk chocolate in beg = 56
Step-by-step explanation:
Given:
Probability of randomly choosing a dark chocolate = 3/8
Number of dark chocolate = 21
Find:
Number of milk chocolate in beg
Computation:
Number of milk chocolate in beg = Number of dark chocolate / Probability of randomly choosing a dark chocolate
Number of milk chocolate in beg = 21 / [3/8]
Number of milk chocolate in beg = 21[8/3]
Number of milk chocolate in beg = 7[8]
Number of milk chocolate in beg = 56

Step-by-step explanation:
Given
See attachment
Required
[tex]P(New\ House)[/tex]
This is calculated as:
[tex]P(New\ House) = \frac{New\ House}{Total}[/tex]
From the attachment, we have:
[tex]New\ House = 60^o[/tex]
[tex]{Total}= 360^o[/tex] --- total angle in a pie chart
Note that the measurements must be converted to degrees (if not already in degrees).
So, we have:
[tex]P(New\ House) = \frac{60}{360}[/tex]
Simplify
[tex]P(New\ House) = \frac{1}{6}[/tex]
