Answer:
11 bicycles and 14 tricycles
Step-by-step explanation:
11 bicycles would be 22 wheels in total.
14 tricycles would be 42 wheels in total.
11 + 14 = 25 bikes and 22 + 42 = 64 wheels.

To balance a seesaw, the distance a person is from the fulcrum is inversely proportional to his or her weight . Roger , who weighs 120 pounds is sitting 6 feet from the fulcrum . Ellen weighs 108 pounds . How far from the fulcrum must she sit to balance the seesaw ? Round to the nearest hundredth of a foot .
Answer:
[tex]d_e =6.67ft[/tex]
Step-by-step explanation:
From the question we are told that:
Weight of Roger [tex]W_r=120\ pounds[/tex]
Distance of Roger from fulcrum [tex]d_r=6 ft[/tex]
Weight of Ellen [tex]W_e=120\ pounds[/tex]
Generally the equation for distance-weight relationship is mathematically given by
[tex]d\alpha \frac{1}{W}[/tex]
[tex]\frac{d_1}{d_2} =\frac{W_2}{W_1}[/tex]
[tex]\frac{d_r}{d_e} =\frac{W_e}{W_r}[/tex]
Therefore
[tex]\frac{d_e}{d_r} =\frac{W_r}{W_e}[/tex]
[tex]d_e =\frac{W_r*d_r}{W_e}[/tex]
[tex]d_e =\frac{6*120}{108}[/tex]
[tex]d_e =6.67ft[/tex]
Therefore the distance from the fulcrum she must sit to balance the seesaw is given as
[tex]d_e =6.67ft[/tex]

slope = rise/run
rise = -3 ... move down 3 units
run = 4 .... move to the right 4 units
============================================
Work Shown:
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-17-(-2))/(24-4)
m = (-17+2)/(24-4)
m = -15/20
m = -3/4 is the slope
----------------
It basically means "move down 3 units, and move to the right 4 units"
So, slope = rise/run = -3/4
rise = -3 = move down 3 units
run = 4 = move to the right 4
You could express the slope as a decimal, and that would be -3/4 = -0.75, but you lose the rise and run values. So I recommend you keep the fraction.
Another problem with decimals is that sometimes we could have approximations that aren't exact. For example, if the slope was 2/3, then that approximates to 0.667 which may cause rounding errors down the line. Though I should point out that decimals do have their advantages in some cases.

You ran 10 blocks in 5 minutes, and you ran at a consistent speed, how long did it take to run 1 block?
Answer:
30 seconds
Step-by-step explanation:
10 ÷ 10 = 1 block
5 ÷ 10 = 0.50
0.50 of a minute is 30 seconds
Given the following probabilities, determine whether
the events A and B are independent or dependent.
P(a) x p(b) = 2/5 x 1/4 = 2/20 = 1/10
1/10 does not equal 1/9 so the event is dependent
The answer is B ( the second choice)

f(x) = x^2 - 16 What are the solutions for x when f of x equals 9?
Answer:
65
Step-by-step explanation:
This one is very confusing please help.
Answer:
H was (Hx,Hy) goes to (Hy,-Hx)
G was (Gx,Gy) goes to (Gy,-Gx)
I was (Ix,Iy) goes to (Iy,-Ix)
Step-by-step explanation:
Rotating about the (0,0), the distance from any point to the origin (the hypotenuse of the triangle formed) never changes. A 90 clockwise rotation moves the point to the next quadrant, so side a and side b must flip to maintain the distance. You just need to flip the coordinates and change the sign of the new Y. If you plot a few random points and use a compass to rotate them 90 I think you will find this works.

Mia hired a moving company. The company charged $50l for services, and Mia gives the movers a16% tip how much does Mia tip the movers?
Answer:
$8
Step-by-step explanation:
We are told in the above question:
Mia hired a moving company. The company charged $50l for services, and Mia gives the movers 16% tip
The amount of money that Mia tips the movers is calculated as:
16% of $50
16% × $50
16/100 × $50
= $8
Therefore, Mia tips the movers $8

Actually Welcome to the concept of Angles sum property.
Since the total angle is 90° , hence we get the equation as,
==> 33° + 6x + 3° = 90°
==> 36° + 6x = 90°
==> 6x = 90 - 36
==> 6x = 54°
hence, x = 54/6 = 9°
so, we get as,
==> 6x+3 ==> 6(9)+3 = 54+3 ==> 57°
Answer:
The answer to your question is --- 6x+3 --- 6(9)+3 + 54+3 --- 57°
Step-by-step explanation:
33° + 6x + 3° = 90°
36° + 6x = 90°
6x = 90 - 36
6x = 54°
x = 54/6 = 9°
I hope this helps and have a wonderful day!

The probability of drawing a blue
marble from a bag containing
these marbles is į
If you replace the marble each time,
predict how many times a blue marble
will be chosen out of 50 draws.
[?] times
Enter
Answer:
25 times
Step-by-step explanation:
From the question:
Number of :
Yellow = 2
Red = 3
Blue = 5
P(blue) = required outcome / Total possible outcomes = 5/ 10 = 1/2
If marble is drawn with replacement :
Number of times a blue marble is drawn from 50 trials :
P(blue marble) * 50
1/2 * 50
= 25 times

Use this set of number to answer the question.
4, 11, 6, 9, 23, 34, 6, 19,
What is the median for this set of numbers?
A. 6
B. 10
C. 14
D. 16
Answer:
10
Step-by-step explanation:
arrange the number in order from smallest to largest, 4, 6, 6, 9, 11, 19, 23, 34. you then find the middle number, in this case there is no middle number, but 9 and 11 are the closest, so you add those to together to get 20, then divide by 2. this gives you ten
if you have any questions, leave them in the comments and i will try to answer them, if this helped pls give brainliest
Answer:
Hello There!!
Step-by-step explanation:
Median is ordering the numbers from smallest to biggest.
Ordered: 4,6,6,9,11,19,23,34
And there is no middle number so you have two add the two middle numbers 9+11=20 then divide by 2 which equals 10.

Which bacteria sample (A or B) had a smaller initial population? What was that value?
Answer:
B has a smaller initial population of 500
Step-by-step explanation:
Given
See attachment for complete question
Required
The bacteria with the smaller initial population
The initial population is at x = 0
For bacteria A;
[tex]A(x) = 600[/tex] when [tex]x = 0[/tex]
For bacteria B, we have:
[tex]B(x) = 500(2)^x[/tex]
Substitute 0 for x
[tex]B(x) = 500(2)^0[/tex]
[tex]B(x) = 500*1[/tex]
[tex]B(x) = 500[/tex]
So; when x = 0
[tex]A(x) = 600[/tex] and [tex]B(x) = 500[/tex]
Because; 500 < 600
We can conclude that B has a smaller initial population of 500
A 12 foot ladder is leaning up against the side of a building. The bottom of the ladder is 4 feet away from the bottom of the building Approximately how high up the side of the building does the ladder reach? 8 ft 10 ft 11 ft 12 ft
You can use the Pythagoras theorem for this since a right triangle is formed.
[tex]c^2 = a^2 + b^2[/tex]
C = 12
A = 4
B = x
Input values:
[tex]12^2 = 4^2 + x^2[/tex]
[tex]144 = 16 + x^2[/tex]
[tex]128 = x^2[/tex]
[tex]x = \sqrt{128}[/tex]
[tex]x = 11.3137...[/tex]
So, about 11ft.
2. Aaron baked two identical cakes. He cut one into 9 equal slices and the other into 19 equal slices.
a) Show that ⅔ of the 9-slice cake gives the asme number of pieces as 1/
3 of the 18 slice cake.
2/3 x 9 = 6 slices
1/3 x 18 = 6 slices
Hence they give the same number of slices.
Find the slope of the line that passes through the points
(-5,-6) and (5,10)
Answer:
8/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (10- -6)/(5 - -5)
= (10+6)(5+5)
= 16/10
= 8/5
1.6
Step-by-step explanation:
change in y ÷ change in x
(10--6)=16
(5--5)=10
16÷10=1.6
