A diver dove from a board that was 6 3/4 feet above the water's surface, and descended until he was 8 1/3 feet below the water's surface. What was the total distance that the diver desceded?
Answer:
15 1/12 feet
Step-by-step explanation:
Well if he descended 8 1/3 feet below the water, that means he must've went from board to water which is 6 3/4 feet then down 8 1/3 feet
6 3/4 + 8 1/3
= 6 9/12 + 8 4/12
=15 1/12 feet

show your solution 5x + 12 =42
Answer:
6
Step-by-step explanation:
5x+12=42
subtract 12
5x=30
divide by 5
x=6
Answer:
x = 6Step-by-step explanation:
5x + 12 = 42=> 5x = 42 - 12=> 5x = 30=> x = 6Conclusion:
Therefore, the answer is 'x = 6'.

Answer: [tex]f(x) = 200(\frac{1}{2})^{x}[/tex]
Step-by-step explanation:
If you plug in the x value(s) to each equation, you can see that [tex]f(x) = 200(\frac{1}{2})^{x}[/tex] is the correct answer because each y value matches the y value on the table. Therefore, [tex]f(x) = 200(\frac{1}{2})^{x}[/tex] is the correct answer.

m11=54°
m8=117°
m7=63°
Step-by-step explanation:
a) m2=m12 (corresponding angles)
m12=126°
180=m12+m11 (supplementary angles equal 180)
180=126+m11
m11=54°
b) m14=m8. (corresponding angles)
m8=117°
C) m7=180-m8 (supplementary angles equal 180)
m7=180-117
m7=63°

A town has approximately 1000 homes. The town council is considering plans for future development. Plan A calls for an increase of 200 homes per year. Plan B calls for a 10% increase each year. Write a function to model each plan and determine the number of homes each plan has after 3 years.
Answer:
Plan A: 1600 homes after 3 years Plan B: 1330 homes after 3 years
Step-by-step explanation:
Plan A.
200x3=600
1000+600=1600
1600 homes after 3 years
Plan B.
10% the first year =100 homes increased
10% the secound year = 110 homes increased
10% the third year = 121 homes increased
1330 homes after 3 years
It would be 1330 for plan B. And plan a 1600.

y = mx + c
Find the value of y when m= -2, r = -7 and c= -3.
Answer:
This assume the equation is 35y = mx + c, and that r is meant to be x.
Step-by-step explanation:
35y = mx + c
35y = -2(-7) - 3
35y = 14 - 3
35y = 11
y = (11/35)

Hello, Can you please take a look at this screenshot I have below, This problem is confusing :/
Answer:
See answers below.
Step-by-step explanation:
m ∠A + m ∠B + m ∠C = 180° The sum of the angles in a triangle = 180
28° + x - 4 + 2x = 180° Substitution
x = 52° Algebra
28° + x - 4 + 2x = 180°
24° + 3x = 180°
3x = 156°
x = 156/3
x = 52°
Check: 28° + 48 + 104° = 180√

Answer:
x = 12
Step-by-step explanation:
First:
[tex]27=9*3=3*3*3=3^3[/tex]
If you rewrite the 27 into base 3 like that:
[tex]3^{5x}=3^{(3)\times(2x-4)[/tex]
Now that both sides have the same base, you can cancel them out. This is the simplest example of that I can think of:
[tex]2^x=2^x[/tex]
Here, the exponent obviously has to be equal for this to be true, right? The exponents do have to be equal, so you can drop the bases completely:
[tex]x=x[/tex]
Same for the problem we have above. It's a base 3 on both sides, and for them to be equal, the exponents also have to be equal.
[tex]3^{5x}=3^{(3)\times(2x-4)}\\5x=(3)\times(2x-4)\\5x=3(2x-4)[/tex]
Now, you can simply solve for x.
[tex]5x=6x-12\\-1x=-12\\x=12[/tex]

Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
