Answer: 40 times

Step-by-step explanation:

Given: Total planks = 20

By using integers, Steps forward is represented by +5, Steps backward s represented by  -4.

After first set of two steps ( one forward another backward), 5-4 =1 step forward is captured.

For 20 planks , we require 20 such sets, i.e. he will do this 2x 20 times i.e. 40 times.

Hence, he will do this 40 times to reach the other side.

Answer:

Step-by-step explanation:

we have we know that see the graph

Let

Find the slope B   The slope is positive

so

The graph is increasing in the interval----------> (10, ∞)

Find the slope AB

The slope is negative

so

The graph is decreasing in the interval----------> (-∞,10)

therefore

Answer: $31.50

Step-by-step explanation:

We are told that the price of a baseball card was purchased for $6 but that the value of the baseball card has increased by 425%.

The current value of the baseball card would be:

= $6 + (425% × $6)

= $6 + (425/100 × $6)

= $6 + (4.25 × $6)

= $6 + $25.5

= $31.50

Step-by-step explanation:

Number of bushels after 5 days

= 120 - 5(16.75)

= 36.25 = 36 1/4 bushels.

Step-by-step explanation:

x=4

Answer:

80 minutes

Step-by-step explanation:

Represent Plan A as y = $26.50 + ($0.35/min)x, where x is the number of minutes consumed.  

Represent Plan A as y = $42.50 + ($0.15/min)x

We set these two equations equal to one another and solve for x, the number of minutes at which the costs of the two plans are momentarily equal:

y = $26.50 + ($0.35/min)x = y = $42.50 + ($0.15/min)x

Combining like terms, we get:             ($0.20/min)x = $16.00

                  $16.00

Then x = -------------------- = 80 minutes

                 ($0.20/min)

Answer:

2

Step-by-step explanation:

Remark

You are going to set up a proportion. The sides used are opposite the chosen angles.

Givens

x is opposite an angle marked by 2 arcs.

5 is opposite an angle marked with 1 arc.

8 is opposite an angle marked with 2 arcs

20 is opposite an angle marked with 1 arc.

Equation

x/5 = 8/20              Cross Multiply

20x = 5*8

20x = 40

x = 40/20

x = 2

Answer:

56, 72, and 198.

Step-by-step explanation:

Hope this helped! :)

Answer:

Here are a few ways that I do that:

18 * 5 is the same as (10 + 8) * 5, which equals 50 + 40, which is 90

It's also the same as (20 - 2) * 5, which equals 100 - 10, again, 90

It's also 9 * 2 * 5, which equals 9 * 10, or 90

It's also 3 * 6 * 5, or 3 * 30, which is 90.

Answer:

384 dog

Step-by-step explanation:

4*12= 48*8 is 384

Answer:

B) 0.4, D) 40% and A) 2/5

Step-by-step explanation:

Part/Whole=%/100

8/20=0.4*100=40%=2/5=0.4

The probability that you will randomly choose a chocolate chip cookie is 2 by 5 and 0.4, and 40%.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 8\div 20\\\\= 2\div 5\\\\= 0.40\\= 40\%[/tex]

Answer:

dimes = 32

quarters = 8

Step-by-step explanation:

set up a system of equations:

let d = # of dimes

let q = # of quarters

d + q = 40

.10d + .25q = 5.2

substitution method; let 'q' = 40 - d

.10d + .25(40 - d) = 5.2

.10d + 10 - .25d = 5.2

-.15d = -4.8

d = 32

q = 40 - 32 = 8

Answer:

Step-by-step explanation:

32 dimes

8 quarters

Answer:  2 vertices

The two vertices in question are (2,0) and (5,0). These are points A and D. These two points are on the x axis, which is the line of reflection. Any point on a line of reflection does not move.

The points (0,-3) and (3,-3) are not on the line of reflection, so they do move and are reflected to another location. Refer to the diagram below.

Answer:

The answer is A

Answer:

48

Step-by-step explanation:

4x=148+44

4x=192

x=48

Answer:

Step-by-step explanation:

there are 360 degrees inside any 4-sided polygon

so add all four angle measures and set equal to 360:

3x + x + 44 + 148 = 360

4x + 192 = 360

4x = 168

x = 42

check:

3(42) + 42 + 44 + 148 should equal 360

126 + 42 + 192 = 360

168 + 192 = 360

360 = 360

Answer:

I am pretty sure its the first one

I would say the bottom right graph (D) best fits the data because it passes through the most points possible on the graph.

Answer:

7:4 would be the ratio I think

Answer:

Social Security = $385.83

Medicare = $90.23

Step-by-step explanation:

Social security rate in 2021 is 6.2% on your first $142,800 for the year. Shelly has not reached that threshold so her Social security tax is:

= 6.2% * 6,223

= $‭385.83

Medicare has no threshold and the rate in 2021 is 1.45%:

= 1.45% * 6,223

= $90.23

Step-by-step explanation:

We have

Summer membership + $12 = 3(Weekend pass).

=> ($78) + ($12) = 3x

=> 3x = $90

=> x = $30.

Hence the weekend admission is $30.

Answer:

3x-12=78

Step-by-step explanation:

This is my thinking:

So because x is the cost of the weekend admission, the problem says 12 less than 3 times the cost of the weekend admission. The 3 times the cost of the weekend admission is the 3x, and the problem says 12 less than and that is the -12. And the whole equation is being taken from 78, so

3x-12=78.

Answer:

4.2

Step-by-step explanation:

Hypotenuse ² = opposite ² + adjacent ²

Opposite = 3

Adjacent = 3

Hypotenuse ² = opposite ² + adjacent ²

Hypotenuse ² = 3² + 3²

Hypotenuse ² = 9 + 9

Hypotenuse ² = 18

Find the square root of both sides

√Hypotenuse² = √18

Hypotenuse = √18

Hypotenuse = 4.2426406871192

Hypotenuse = 4.2 to the nearest tenth
