11. Caroline wraps packages at a store. She wraps

Mathematics
1 answer:
Eddi Din [679]4 years ago
8 0

Answer:

<em>C. in five hours Caroline wraps an odd number of packages</em>

Step-by-step explanation:

<em>for</em><em> A until hours you would multiply 2 by 9 and 2 by 9 is 18 and that's an even number so it's not A.</em>

A eliminated.

for B in 3 hours 3 by 9 is 27 and that's an odd number so B is automatically eliminated.

<em>for C in 5 hours all you would do is multiply the 9 by 5 and 9 by 5 is 45 and 45 is indeed an odd number so C is your answer.</em>

<em>for D 7 by 9 is 63 and 63 is an odd number so we already know that C is the answer but still we got to check and D is wrong because 63 is not an even number.</em>

Liam is saving up for a new cell phone. He uses the equation P= I + HB, where P is the cost
Stels [109]

Answer:

H=\dfrac{P-I}{B}

Step-by-step explanation:

Given the expression: P= I + HB

Where:

  • P = cost  of the phone Liam is saving for.
  • I = amount of money he started with.
  • H = number of hours he  babysits
  • B = hourly rate for babysitting.

We want to find an expression for H, the number  of hours Liam will need to babysit to save enough money for a cell phone.

Our goal is to isolate the variable H in the expression P= I + HB.

P= I + HB

Subtract I from both sides

P-I=I-I+HB

HB=P-I

Divide both sides by B

\dfrac{HB}{B} =\dfrac{P-I}{B}\\\\$Therefore\\\\H=\dfrac{P-I}{B}

Simplify the question above
andrey2020 [161]

Answer:

1 +  \frac{3}{x}

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

\frac{ {x}^{2} -  {3}^{2}  }{ {x}^{2}  - 3x}

2) use difference of squares: a² - b² = ( a + b ) (a - b).

\frac{(x + 3)(x - 3)}{ {x}^{2}  - 3x}

3) Factor out the common term x.

\frac{(x + 3)(x - 3)}{ x(x  - 3)}

4) Cancle out x - 3 .

\frac{x + 3}{x}

5) Simplify.

1 +  \frac{3}{x}

Aaron and noah wanted to have a contest to see which of their paper airplanes could fly the longest distance. Aaron's plane flew
Marina CMI [18]

Aaron's plane flew 3.21 meters further than Noah's plane.

<u><em>Explanation</em></u>

Aaron's plane flew 4 meters and Noah's plane flew 79 centimeters.

So, first we need to <u>convert 79 centimeters into meters</u>.

We know that, 1 centimeter = 0.01 meter

So, 79 centimeters = (0.01*79)meter= 0.79 meter

Now, the difference of distance between Aaron's plane and Noah's plane is (4-0.79) meters = 3.21 meters

Indicate the equation
KiRa [710]

Answer:

Slope - intercept form

    y = \frac{3}{5} x - \frac{26}{5}

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the point (2,-4) and slope m = \frac{3}{5}

Equation of the straight line passing through the point (x₁, y₁) and slope 'm'

     y - y₁ = m( x-x₁ )

    y - (-4) =  \frac{3}{5}( x-2)

⇒  5( y+4) = 3(x-2)

⇒  5 y +20 = 3x -6

⇒ 3x - 5 y -6-20 =0

⇒ 3 x -5y -26=0

<u><em>Step(ii):-</em></u>

Slope - intercept form

       5 y = 3x -26

         y = \frac{3}{5} x - \frac{26}{5}
