During a scuba dive, Lainey descended to a point 18 feet below the ocean surface. She continued her descent at a rate of 25 feet per minute. Write an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 143 feet below the ocean surface. Use the variable t for time.

Answer:

Step-by-step explanation:

By the Pythagorean Theorem

[tex]52=x^2+16\\ \\ x^2=52-16\\ \\ x^2=36\\ \\ x=\sqrt{36}\\ \\ x=6[/tex]

From the picture we see that the base is 8. The vertical line representing the length of x cuts the base into two equal parts. Knowing this fact allows us to use the Pythagorean Theorem.

(leg)^2 + (leg)^2 = (hypotenuse)^2

(4)^2 + (x)^2 = [sqrt{52}]^2

16 + x^2 = 52

x^2 = 52 - 16

x^2 = 36

sqrt{x^2} = sqrt{36}

x = -6 and x = 6.

We reject x = -6 because length is never negative.

Answer: x = 6

r= [tex] \sqrt{117} [/tex]

Answer:

10.81665383 about 10.8 units

Step-by-step explanation:

how to find the hypotenuse is a^2 + b^2 = c^2

a = 9

b = 6

9^2 + 6^2

9 x 9 = 81

6 x 6 = 36

81 + 36 = 117

177 = c^2

find the square root of 177 = 10.81665383 about 10.8

Answer:

Step-by-step explanation:

J(x)=b(x)

3x-2=|x+2|

3x-2=±(x+2)

when 3x-2=x+2

3x-x=2+2

2x=4

x=4/2=2

when 3x-2=-(x+2)

3x-2=-x-2

4x=-2+2=0

x=0

it is rejected as 0-2≠|0+2|

or -2=2

so x=2

Answer:

Open circle at 0 arrow to the left

Open circle at 5 arrow to the right

Step-by-step explanation:

numbers that are negative is asking for everything to the left of 0. not inclusive though because 0 is not negative.

Open circle at 0 arrow to the left

Numbers greater than 5 will be to the right of five. Not inclusive because it doesn't ask for numbers equal to 5 too.

Open circle at 5 arrow to the right

Answer:

Answer:

x = 20

Step-by-step explanation:

You can solve this problem using similar triangles; you know the triangles are similar due to the AAA property because of the Corresponding Angles Theorem.

To find x, you need to identify what sides 8 and x correspond to:

8 corresponds to 14 (6 + 8)

x corresponds to (x + 15)

Now, you need to find the scale factor by dividing 14 by 8:

14 ÷ 8 = 7/4

At this point, you can write and solve an equation for x:

7/4x = x + 15

3/4x = 15 (subtract x from both sides)

x = 20 (multiply both sides by 3/4)

Answer:

82

Explanation:

78 respondents aged 18 to 22 use face book and 4 respondents aged 18 to 22 do not use face book. since there are no other options for the survey, the total number of students who were surveyed that are aged 18 to 22 would be 78 + 4 = 82.

i hope this helps! :D

The number of students in the age category of 18 to 22 is 82.

Using the two - way table Given ;

The Number of students in the age category of 18 to 22 include :

(Number of those who use fb + number of those who do not use Fb)

Number who uses Fb = 78

= 78Number who do not use Fb = 4

Hence, The Total number surveyed between age 18 to 22 = (78 + 4) = 82.

Step-by-step explanation:

Answer:

25!!

Step-by-step explanation:

One side(s) = x+6

Perimeter (4s)= 124

4(x+6) = 124

4x + 24 = 124

4x = 124-24

x = 100/4 = 25

Answer:

AB=5

Step-by-step explanation:

Triangle TAB is similar to triangle TWE. This can be proven through AA congruency. Because line AB is parallel to line segment WE, angle TAB is congruent to angle TWE (corresponding angles) and angle TEW is congruent to angle TEW(corresponding angles). Now, having proved that triangle TAB is similar to triangle TWE, we know that similar triangles have proportional sides. We can do [tex]\frac{TB}{AB} = \frac{TE}{WE}[/tex], plug in values for [tex]\frac{4}{AB} = \frac{16}{20}[/tex]  , simplify   [tex]\frac{4}{AB} = \frac{4}{5}[/tex], both fractions have a four in the numerator and must be equal to each other so AB=5.

16h=48

h=3

It's a good idea to get into the habit of

using parenthses when substituting

numbers in for variables.

Since x = -4 and y = -2, 5x - y is 5(-4) - (-2).

Now, 5(-4) is -20 and minus a negative 2

can be thought of as plus a positive 2.

So we have (-20) + (+2) which equals -18.

Answer:  36k or 36 * k

Step-by-step explanation:

Each ticket costs $36 each and there are k tickets to b purchased.

To find the cost, you need to multiply the cost of one ticket by the total number of tickets which is k:

= 36 * k

That is the relevant equation.

For instance, assume k is 5. The cost of 5 tickets would be:

= 36 * k

= 36 * 5

= $180

Answer: x > -11

Step-by-step explanation:

-5x+9<64

-5x<55

x > -11

The sign flips bc you are diving by a negative number.

Answer:

[tex]x > - 11[/tex]

Step by step explanations:

1) Subtract 9 from both sides.

[tex] - 5x < 64 - 9[/tex]

2) Simplify 64 - 9 to 55.

[tex] - 5x < 55[/tex]

3) Divide both sides by -5.

[tex]x > - \frac{55}{5} [/tex]

4) Simplify 55/5 to 11.

[tex]x > - 11[/tex]

therefor, the answer is x > - 11.
