Javier works each weekend at an animal shelter. He earns $8 an hour. He is saving his earnings to go on a ski trip that costs $190.

Becca says that Javier must work at least 6 more hours to have enough money to go on the ski trip. Her work is shown below. Choose True or False about each statement

Becca's solution included all of the hours Javier worked on both weekends. (TRUE OR FALSE?)

Javier worked a total of 23 hours on both weekends. (TRUE OR FALSE?)

Javier earns $198 for 24 hours of work. (TRUE OR FALSE?)

Javier only needs to work one more hour to have enough money for his trip. (TRUE OR FALSE?)

Answers

Answer:

Becca's solution included all of the hours Javier worked on both weekends.

Step-by-step explanation:

Javier needs to work at least 6 more hours. He will earn:

6*8 = $48

He has already got:

$190 - $48 = $142

He worked:

142/8 = 18 hours (rounded)

Total he will have worked:

18 + 6 = 24 hours

Answer choices:

Becca's solution included all of the hours Javier worked on both weekends.

TRUE

Javier worked a total of 23 hours on both weekends.

FALSE. 23*$8 = $184 < $190

Javier earns $198 for 24 hours of work.

FALSE. 24*8 = $192

Javier only needs to work one more hour to have enough money for his trip.

FALSE. Becca says 6 more hours required.

Solve 2x=54xˆ(2/3)

Please, I need the step by step working to find the value of x

Answers

Answer:

x = 19683 or x = 0

Step-by-step explanation:

Solve for x:

2 x = 54 x^(2/3)

Hint: | Isolate the radical to the left hand side by reversing the equality.

2 x = 54 x^(2/3) is equivalent to 54 x^(2/3) = 2 x:

54 x^(2/3) = 2 x

Hint: | Eliminate the power on the left hand side.

Raise both sides to the power of three:

157464 x^2 = 8 x^3

Hint: | Move everything to the left hand side.

Subtract 8 x^3 from both sides:

157464 x^2 - 8 x^3 = 0

Hint: | Factor the left hand side.

Factor x^2 and constant terms from the left hand side:

-8 x^2 (x - 19683) = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by -8:

x^2 (x - 19683) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x - 19683 = 0 or x^2 = 0

Hint: | Look at the first equation: Solve for x.

Add 19683 to both sides:

x = 19683 or x^2 = 0

Hint: | Look at the second equation: Eliminate the exponent.

Take the square root of both sides:

Answer: x = 19683 or x = 0

What is 4/9 x 5/7 x 1/2

Answers

Answer:

0.16

Step-by-step explanation:

4*5*1=20

9*7*2=126

20/126=10/63

Answer:

10/63

Step-by-step explanation:

First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

what is the equation of the following? Someone could help me to understand this? thank you​

Answers

Answer:

y=(1/5)x

Step-by-step explanation:

First, we must find the slope of the line.

The slope of a line can be found using the formula: (y2-y1)/(x2-x1)

(3-0)/(15-0)

(3)/(15)

1/5

The slope is 1/5.

Next we find the y-intercept, or where the line crosses the y-axis. In this case, the y-intercept is 0.

This gives us the equation: y=(1/5)x

We conclude that:

h(f(-1))  = -2

∴ option D i.e. -2 is correct.

Step-by-step explanation:

Given

f(x) = 4x² - 1

g(x) = 1/2x + 5

h(x) = 2(x - 4)³

To determine

h(f(-1)) = ?

In order to determine h(f(-1)) first we need to determine f(-1).

substitute x = -1 in the function f(x) = 4x² - 1

f(-1) = 4(-1)² - 1

f(-1) = 4(1) - 1

f(-1) = 4-1

f(-1) = 3

so

h(f(-1)) = h(3)

now substitute h = 3 in the function h(x) = 2(x - 4)³

h(x) = 2(x - 4)³

h(3) = 2(3 - 4)³

h(3) = 2(-1)³

h(3) = 2(-1)

h(3) = -2

Thus,

h(f(-1)) = h(3) = -2

Hence, we conclude that:

h(f(-1))  = -2

∴ option D i.e. -2 is correct.

302.833 rounded to the nearest whole number​

Answers

Answer:

303

Step-by-step explanation:

Step-by-step explanation:

When rounding a decimal to the nearest whole number, we look at the tenths place. If it is {5,6,7,8,9} we round the ones place up. If it is {0,1,2,3,4} the ones place stays the same.

For 302.833, the tenths place is 8.

Therefore we round 302.833 up to 303.

The answer is 303.

Find the slope of the line passing through the pair of points.
(-4,5) and (0, 2)

Answers

Answer:

y = 3/-4x + 2

Step-by-step explanation:

Answer:

slope = [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

1) To find the slope between a pair of points, use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. We know the line passes through (-4,5) and (0,2). So, substitute their x and y values for the formula (following the appropriate order) and solve:

[tex]\frac{(2)-(5)}{(0)-(-4)} \\= \frac{2-5}{0+4} \\= \frac{-3}{4}[/tex]

Thus, the slope is [tex]-\frac{3}{4}[/tex]
