A scuba diver is 20 feet below the surface of the water 14 seconds after he entered the water and 100 feet below the surface after 30 seconds.  What is the scuba divers rate of change?

Answer: only one line

Step-by-step explanation:

The total budget was = $324

The percentage of budget spent = 80%

The cost of 80% of budget spent on scooter = $259.20

But the percentage of total budget = 100%

Therefore the cost of total budget =

[tex] \frac{100 \times 259.20}{80} [/tex]

[tex] \frac{25920}{80} [/tex]

= 324

Therefore the cost of the total budget = $324

Step-by-step explanation:

Let x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced.

The total no of cabinets are 100

Equation will be : x+y = 110

We can write it as : y = 110-x ...(1)

Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20.

Equation will be : y = 2x + 20 ...(2)

Put the value of y from equation (1) into equation (2).

110-x = 2x + 20

Combining like terms,

110-20 = 2x+x

90 = 3x

x = 30

Put the value of x in equation (1) :

y = 110-30

y = 80

Hence, there are 30 cabinets of type 1 and 80 cabinets of type 2.

Answer:

19.79+x >= 25

x>=5.21

Step-by-step explanation:

Step-by-step explanation:

2x + 3x + 4x = 180

9x = 180

x = 20

2x = 2(20)=40

3x = 3(20)=60

4x = 4(20)=80

                                             Question 27

The graph on question 27 indicates that there are three points with the locations such as:

In other words, there are three points that lie on the graph with the x-values such as:

{(2, 6), (4, 12), (6, 18)}

We know that the domain includes the set of x-values.

Hence, the domain of the function is:

Since the points are not connected between them. In other words, there is not a continuous line.

Thus, the function represented on the graph has a discrete domain.

                                        Question 28

The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).

Since there is a continuous line between the points from x = 0 to x = 7.

Thus, the domain of the line function is:

As the line segment is a continuous line. Thus, the domain is continuous.

Given:

[tex]5^2\times 5^{x-5}=625[/tex]

To find:

The value of x.

Solution:

We have,

[tex]5^2\times 5^{x-5}=625[/tex]

It can be written as

[tex]5^2\times 5^{x-5}=5\times 5\times 5\times 5[/tex]

Using property of exponents, we get

[tex]5^{2+x-5}=5^4[/tex]            [tex][\because a^m\times a^n=a^{m+n}][/tex]

[tex]5^{x-3}=5^4[/tex]

Comparing the exponents on both sides, we get

[tex]x-3=4[/tex]

Adding 3 on both sides, we get

[tex]x=4+3[/tex]

[tex]x=7[/tex]

Therefore, the value of x is 7.

Step-by-step explanation:

Angles APD, DPC and CPB are supplementary. (Angles on a straight line)

Therefore Angle APD + Angle DPC + Angle CPB = 180°.

Since Angle DPC = 90° (Right angle),

Angle APD + Angle CPB = 180° - 90° = 90°.

=> (7x + 1) + (9x - 7) = 90

=> 16x - 6 = 90

=> x = 6

Hence arc measure of minor arc AD

= (7x + 1)° = [7(6) + 1]° = 43°.

The fraction of the trip completed is ³/₈

The fraction of the trip completed in decimal form is 0.375

Step-by-step explanation:

Given;

total trip to be completed by Tora, = 320 miles

distance completed by Tora, = 120 miles

The fraction of the race that Tora has completed is given as;

[tex]= \frac{distance \ completed}{total \ distance} \\\\= \frac{120}{320}\\\\= \frac{12}{32} \ (divide \ both \ numerator \ and \ denominator \ by \ 4)\\\\= \frac{3}{8}[/tex]

As a decimal the fraction is written as;

[tex]\frac{3}{8} = 0.375[/tex]

Answer:

y=2x+5

Step-by-step explanation:

Let's solve for y.

−2x+y=5

Step 1: Add 2x to both sides.

−2x+y+2x=5+2x

y=2x+5

Answer:

y = 2x + 5

Step-by-step explanation:

-2x + y = 5 or y -2x = 5

We want what y equals so we need to isloate it. To do this, we need to add2x to both sides. This will cancel the 2x on the left side and now we have y alone. Remember, you have to do it to both sides. Therefore:

y = 2x + 5

Note: This equation is in slope-intercept form, y= mx + b

If this was the equation of a line:

  m (slope) = 2

  b (y-intercept) = 5

There are 168 cookies. 14 times a dozen (12) is 168.

The ratio of cups of sugar to cookies is 7.5 to 168.

If you want to find the cups of sugar you need for 168, divide 7.5 and 168 by 168.

168/168=1

7.5/168 is about 0.04.

The cups of sugar you use for one cookie is 0.04.

Ok we can see that [tex]2z^4[/tex] contains the variable with the highest exponent, 4, so the degree is 4.

Answer: a = 45°

Step-by-step explanation:

The measure of∠PSR is given: 90°

Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.  

The total of all angles in a triangle is 180. So subtract 90, then divide by 2.

180-90 = 90

90/2 = 45

a = 45°

If "b" is supposed to be the measure of ∠SRQ, that is 15°  The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15

Answer:

Washing Cars: $33

Clearing Tables: $91

Step-by-step explanation: Multiply 11 by 3, and multiply 13 by 7. I hope I helped!

Step-by-step explanation:

for every 1 hour she works she gets 11 dollars washing the cars, so you multiply the number of hours by the amount of money she gets each hour. Like so,

11 x 3 = 33, so 33 dollars from washing cars

next - 13 x 7 = 91 dollars from house cleaning

add together the amount of each so, 33 + 91 = 124, 124 is the answer.
