Answer:
a.[tex]R=10-24t[/tex]
b.[tex]B=6+6t[/tex]
Step-by-step explanation:
We are given that
Speed of red bike, v=24 km/h
Speed of blue bike, v'=12km/h
Distance of red bike when t=0
=10 km north
Distance of blue bike when t=0
=6km east
a. We have to find the expression of distance of red bike from Lawrence.
[tex]Distance=speed\times time[/tex]
Let t be the time taken by red bike
Distance of red bike from Lawrence is given by
[tex]R=10-24\times t[/tex]
[tex]R=10-24t[/tex]
b.
Distance of the blue bike from Lawrence
[tex]B=6+6\times t[/tex]
[tex]B=6+6t[/tex]

Answer:
10.-8/-2 can't represent calculating a mean change in score because a mean change in score is counted by adding up the scores & then dividing it by the number of the scores. As a number of scores can never be negative, so -8 can't be divided by -2 . So, -8/-2 can't represent this.
6. a) Andrea's mean weekly change will be negative. Because after adding up her weekly changes, we'll find a negative number. & as the number of weeks is positive, then the mean will be a negative number .
b)the division equation is: -15/5
So, her mean weekly change is -3

Solve the system by substitution.
y = 4x – 8
Y = 2x
first one if u solve for y is y=4x-8
solve for x is x =y/4+2
second one is if u solve for y is y=2x
if u solve for x is x =y/2

Plssss answer it plssss... We need it
Answer:
put each a= number in the place of (a) in the big circle the tiny 2 means to the 2nd power ( the number times itself) .. so you use the small circle a=3 then 3² -7 = 2 meaning 3x3=9 and then 9-7=2 so the answer for that small circle is 2 and then repeat for each small circle
What is the solution of 10(w+5) = 60?
Answer:
w = 1
Step-by-step explanation:
10(w+5) = 60
w+5 = 6
w = 6-5
w = 1
Insta: 25k_kemAnswer: w is 1!
Step-by-step explanation: 5 plus 1 is 6. 6 times 10 is 60! Good luck! :D

9th Grade Honors Geometry
Answer:
The Correct Answer is 4!
Step-by-step explanation:
We know on triangle 1 that 2 of the sides are 2 and 4 and there a right angle, an angle that has 90 degrees
with this we can calculate the top angle to be 26.565 which combined on both sides is equal to 90, lust you will then have to subtract 90 minus 26.565 and you will get 63.435. Now that we know than the top angle is equal to 63.435, the 2nd angle is equal to 90 degrees which by the way resembles a right angle, and that 1 side of the 3 sides is 2 we can conclude though the triangle formula that...

A scientist wants to know if the color of the water affects how much animals drink. The average amount of water each animal drinks was recorded in milliliters for a week and then graphed. Is there evidence to suggest an association between water color and animal?
Answer:
Yes, there is very clear evidence to suggest or show a correlation between
watercolour and each animal's response to the water as well as their total responses.
Explanation
When the water was blue, the total water consumed by both animals came to 1410 ml. The dog consumed more water than the cat. The dog drank 1200 ml while the cat drank just 410 ml.
When the color of the water was changed to green, the animals drank a total of 1300 ml. The cat drank 200 ml while the dog drank 1100 ml.
We can thus, establish that there is an association between the color of the water and the volume of water taken by each animal because on the whole, both animals seem to prefer blue water. They drank more water when its color was blue and less when it was red.
Please see the attached document.
