Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?
Answer:
I think the answer is 171.
Step-by-step explanation:
Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)

Ben has a music book with 84 songs. He has learned how to play 25% of them. How many songs in the book does Ben NOT know how to play
Answer:
63
Step-by-step explanation:
This is because 25% of 84 is 21. He knows how to play 21 songs. 84-21=63.
63 is how many songs he does NOT know how to play.
Answer:
The answer is 63.
----------------------------------
24% of 84 is 21. 84 - 21 = 63.

Answer:
Step 1: Simplify both sides of the equation.
11(n−3)=−4
(11)(n)+(11)(−3)=−4(Distribute)
11n+−33=−4
11n−33=−4
Step 2: Add 33 to both sides.

Answer:
For the first one
x= About 32.02
y= About 27.58
z= About 55.16
For the second one
x= 6
y= 12
z= about 16.97
Step-by-step explanation:
Their all really simple
These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!
I hope this picture makes you feel better

Which of the following is a correct interpretation of the expression 2 - (-5)
A The number that is 5 to the left of 2 on the number line
B The number that is 5 to the right of 2 on the number line
C The number that is 2 to the left of -5 on the number line
D The number that is 2 to the right of -5 on the number line
Answer:
B
Step-by-step explanation:
when rewriting it, it would be 2+5 because subtracting a negative number is the same as adding.
so it would be 5 to the right(since you are increasing/adding) to 2 (the beginning/starting point)

Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?
Answer:
4 wooden and 3 plastic
Step-by-step explanation:
4 (wooden) × 2 - 5 = 3 plastic
3 (plastic) + 4 (wooden) = 7 total
The number of plastic frames is 4 and the number of wooden frames is 3.
What is equation?
A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given statement:
The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.
The total number of frames sold by Tristan is 7.
Write the equation for the above statement,
p = 2w - 5
Here, p is a plastic frame and w is a wooden frame,
p + w = 7
Solve the equation by using the elimination method,
p = 4 and w = 3
Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=(f(2x)/2) + 2. What is the sum of coordinates of that point?
Answer:
Step-by-step explanation:

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function
The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25
