Answer:
b = 40
Step-by-step explanation:
This is because Jim starts with $40 and then makes $20/lawn. The equation can be represented by y = 20x + 40
Hoped this helped! :)
Assuming they split the loot equally among themselves, the percent that belongs to three robbers is the total amount of loot divided by eight, multiplied by three:
100 / 8 * 3 = 37.5
To find the percentage if two gang members are killed, you would calculate one hundred percent of the loot divided by the quantity eight minus two (to account for the two dead gang members), multiplied by 3:
100 / (8 - 2) * 3 => 100 / 6 * 3 = 50
To find the percent increase, subtract the smaller percentage (original number) from the larger percentage (new number), then divide the increase by the original number and multiply the answer by one hundred.
50 - 37.5 = 12.5
% increase = 12.5 / 37.5 * 100
% increase = 33.3333
Answer:
The percent of the loot that belongs to three robbers is 37.5 percent.
50 percent belongs to them if two of the gang members are killed.
Each robber's share increases by 33.33 percent.
Hope this helps!
Two ways to answer:
A. Using calculus:
H(t)=-16t^2+65t+3
To find maximum of H(t), equate H'(t)=0, or
H'(t)=-32t+65=0 => t=65/32=2.03125, or
t=2.0 s. to the nearest 10
B, Without using calculus, i.e. by completing the square
H(t)
=-16t^2+65t+3
=-16(t^2-65/16t)+3
=-16(t^2-2*(65/32)t+(65/32)^2)+3+(65/32)^2
=-16(t-65/32)^2+3+(65/32)^2
meaning the maximum occurs at (t-65/32)=0, or t=65/32=2.03125
Answer: t=2.0 seconds (to the nearest tenth)

Step-by-step explanation:
if 1 inch equals 2.54 cm then 5ft will be:
=5*2.54
=12.7 cm
therefore, sara's height in centimeter:
=12.7+10
=22.7 cm

Answer: D) 130 </h3>
========================================================
Explanation:
The three upper angles
all combine together to form a 180 degree straight angle. Let's add up the angle expressions and set the result equal to 180. That will help us solve for x.
(angle AOB) + (angle BOC) + (angle COD) = 180
(3x-28) + (90) + (66-x) = 180
2x+128 = 180
2x = 180-128 .... subtract 128 from both sides
2x = 52
x = 52/2 .... dividing both sides by 2
x = 26
Since x = 26, we can find the missing angles like so
- angle AOB = 3x-28 = 3*26-28 = 50
- angle COD = 66-x = 66-26 = 40
Note how:
(angle AOB) + (angle BOC) + (angle COD) = 50+90+40 = 180
to help confirm we have the correct x value.
--------------------------------------
Afterward, we need to find angle BOD which is the combination of angles BOC and COD
angle BOD = (angle BOC) + (angle COD)
angle BOD = 90 + 40
angle BOD = 130
Angles BOD and AOE are vertical angles. It might help to erase ray OC so you can see the two vertical angles better. Vertical angles are always congruent, which means angle AOE is 130 degrees as well.
