Suppose that a scuba diver is currently 34 feet below sea level. If he descends at a rate of 2 feet per minute, in how many minutes will it take for the diver to reach 126 feet below sea level?

Answers

Answer:

46 minutes I think

Step-by-step explanation:

Your already 34 feet down so subtract 34 from 126 which is 92. Put the two aside for a second and divide 90 by 2 which is 45 and since it take 1 minute to get down 2 feet it will take 45 to get down 90. Back to the 2, you will add one more to 45 which is 46 because it will take one more minute to get down those other 2 feet.

For each situation, explain whether you think the relationship is proportional or not. Explain your reasoning.

The weight of a stack of standard 8.5x11 copier paper vs. the number of sheets of paper.
The weight of a stack of different-sized books vs. the number of books in the stack.

Answers

Answer:

A. Yes

B. No

Step-by-step explanation:

We have that,

A. The dimensions of the each of the paper is 8.5 × 11.

Since, the papers have equal dimensions, the weight of every paper will be same and it will be easy to find the number of papers using direct proportion.

Thus, the weight of the paper and the number of papers is proportional.

B. It is given that the weight of each book is different.

Since, all the books have different weights, it is not easy to find the number of papers using direct proportion.

Hence, the weight of the books and the number of books is not proportional.

A: Correct B: Incorrect

HELP, DUE IN 15 MINUTES! In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F correspond to vertices A, B, and C, respectively, and each side of triangle DEF is [tex]\frac{1}{3}[/tex]
the length of the corresponding side of triangle ABC. What is the value of sinF?

Answers

Answer:

Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem

Step-by-step explanation: AB=202−162=400−256=144=12

Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,

sinF=oppositesidehypotenuse=ABAC=1220=35

Therefore, sinF=35.

The final answer is 35 or 0.6.

Answer:

Answer 19:- x = 5

Answer 20:- x = 11

Step-by-step explanation:

Answer 19:-

2x + 10 = 20

2x = 10

x = 5

Answer 20:-

80 + 20x = 300

20x = 220

x = 11

Answer:

19. x = 5

This is because Elise need $20, so we are going to figure out x

First, subtract 10 by both sides

2x = 10

Then, divide both sides by two to isolate the variable

x = 5

5 cars is the minimum

================================================================

20. He can stay for 11 nights.

First we subtract 80 by both sides

20x = 220

Then we isolate the variable by dividing both sides by 20

x = 11

write two equations to help find the answer

Answers

Answer: 41

Step-by-step explanation:

Using a system of equations, it is found that he took 30 students to the movies.

------------------------------

This question is solved using a system of equations, and I will say that:

x is the number of students taken.y is the number of adults taken.

------------------------------

40 people were taken, and thus:

[tex]x + y = 40[/tex]

As we want the number of students x, we can represent y as function of x, thus:

[tex]y = 40 - x[/tex]

------------------------------

Each student costs $4.Each adult costs $6.The total amount spent was $180.

Thus:

[tex]4x + 6y = 180[/tex]

Since [tex]y = 40 - x[/tex]

[tex]4x + 6(40 - x) = 180[/tex]

[tex]4x + 240 - 6x = 180[/tex]

[tex]-2x = -60[/tex]

[tex]2x = 60[/tex]

[tex]x = \frac{60}{2}[/tex]

[tex]x = 30[/tex]

He took 30 students to the movies.
