What is the unit rate of 18?

Answer:

$42

Step-by-step explanation:

if the total without tax is $39.00, add the sales tax.

39.00 + 2.83 = 41.83

rounded would be $42.00

Answer:

Step-by-step explanation:

This is a commission problem. Here is the formula:

P x R

= 5.75 x 0.20

= $1.15

Jack's tip was $1.15. :D

Key: P = Original Price R = Commission Rate

Answer:

The answer is D y=2/5x + 2

Step-by-step explanation:

I find the the slope first by using the slope formula y2 - y1/x2 - x1

Then, I use the slope-intercept formula to find the y-intercept

4 = 2/5(5) + b

4 = 10/5 + b

4 = 2 + b

4 - 2 = 2 - 2 + b

2 = b

So u get:

y=2/5x + 2

6.25 dozens for 75 cupcakes

Step-by-step explanation:

(used a calculator... if I'm wrong, I'm sorry TmT

Answer:

6.25 dozens

Step-by-step explanation:

1 dozen = 12

75 / 12 = 25 / 4

25 / 4 = 6 1 /4 = 6.25

Answer:

The arrow will hit the ground approximately 10.5 seconds after launch.

Step-by-step explanation:

The arrow experiments a free fall motion, which is a particular form of uniform accelerated motion due to gravity and in which air friction and effects from Earth's rotation can be neglected. Then, the height as a function of time ([tex]h(t)[/tex]), measured in feet, is obtained by the following kinematic formula:

[tex]h(t) = h_{o}+v_{o}\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)

Where:

[tex]h_{o}[/tex] - Initial height of the arrow, measured in feet.

[tex]v_{o}[/tex] - Initial velocity of the arrow, measured in feet per second.

[tex]t[/tex] - Time, measured in seconds.

[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.

If we know that [tex]h(t) = 0\,ft[/tex], [tex]h_{o} = 35\,ft[/tex], [tex]v_{o} = 166\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{m}{s^{2}}[/tex], then the following polynomial is obtained:

[tex]35+166\cdot t -16.087\cdot t^{2}=0[/tex] (2)

Lastly, we find the roots of the given expression by the Quadratic Formula:

[tex]t_{1}\approx 10.526\,s[/tex] and [tex]t_{2} \approx -0.207\,s[/tex]

Time is a positive variable and then we conclude that the only solution that is physically reasonable is approximately 10.526 seconds.

The arrow will hit the ground approximately 10.5 seconds after launch.

Answer:

30

Step-by-step explanation:

Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!

Answer:

k = 30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the triangle, thus

k + 90 = 120 ( subtract 90 from both sides )

k = 30

Answer:

C

Step-by-step explanation:

Answer:

No solution

Step-by-step explanation:

There is one variable. so it can't be two solutions. To the rest, we need to solve the equation.

5-2x=3+x-4-3x

5=3-4

5=-1

Impossible!!!

so no solution.

Answer: 81 consecutive free throws

Step-by-step explanation: Since 78 of 90 attempted free throws equals to 88.89%, then try adding 3 to 78, (78 + 3) which equals to 81. If you convert 81/90 to a percentage, you get 90%. So your final result or answer is 81 consecutive free throws.

Tip: To convert a fraction to a percentage, divide the denominator by the numerator and you should get a decimal quotient. Lastly, just add a percentage sign.

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

30% of 20 is 6, but since we are trying to find the number of vanilla cupcakes we take the total original number (which was 20), and subtract 6 (the number of chocolate cupcakes). ANSWER- 14
