A bicycle helmet has a selling price of $50. The helmet is discounted 30% off the selling price. The sales tax rate is 6%. What is the total cost of the helmet?

Answer:

4$ was deducted

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{6\sqrt{3} }{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]

cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

tanA = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{6\sqrt{3} }{6}[/tex] = [tex]\sqrt{3}[/tex]

Answer:

Multiply 4 portion by 4 to make 16 portions

Step-by-step explanation:

Recipe for 4 portions of potato soup:

40 mL oil

50 g onions

300 g potatoes

550 mL milk

Richard follows the recipe but wants to make 16 portions.

Multiply each ingredients by 4 to make 16 portions of potato soup

Recipe for 16 portions of potato soup:

160 mL oil

200 g onions =

1200 g potatoes =

2200 mL milk

Answer:

E = 18750 J

Step-by-step explanation:

The question is "If a car has a mass of 1,500 kg and a speed of 5 m / s, what is the kinetic energy of a car?"

Mass, m = 1500 kg

Speed, v = 5 m/s

We need to find the kinetic energy of the car. The formula for kinetic energy is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 1500\times (5)^2\\\\K=18750\ J[/tex]

So, 18750 J is the kinetic energy of the car.

Answer:

23.5

Step-by-step explanation:

Answer:

23.5

Step-by-step explanation:

Remember...

5 or more? raise the score, 4 and below let it rest

The number in the tenths place, in this case, is 5 and the number next to it is 4, and since 4 is less than 5, you do not round 5 up to 6, you simply leave it alone!

Answer:

1. The volume is 729 V = 729  a Edge  9cm. V=a3=93=729cm3

2. perimeter =2(L+w)  length 4cm width positive

3. Area =121m2. a Side 11cm. A=a2 =112=121m2

4. A = length and width

5.  Perimeter =45 . a side 15cm. P=3 a=3.15=45cm

Answer: 4

Step-by-step explanation:

Slope: [tex]\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]

y₂ = -7

y₁ = 5

x₂ = 0

x₁ = 3

[tex]\frac{-7 -5 }{0- 3 }=\frac{-12}{-3} = \frac{4}{1} = 4[/tex]

Slope: 4

Answer:

x+5

Step-by-step explanation:

15+x-10=x+5

Answer:

Step-by-step explanation:

discriminant = (-24)²  - 4(9)(16) = 0, so there are two identical roots.

That eliminates choices 2 and 4.

Quadratic formula

x = [24 ± √(24² – 4·9·16)] / [2·9]

 = 24 / 18

 = 4/3

9x² - 24x + 16 = 9(x-4/3)² = (3x-4)²

Worker work for =25 days and he paid Rs.4625.

Step-by-step explanation:

From the question,

Worker is paid Rs.1110 for =6 days

Worker is paid Rs.1 for =(6/110) days

Worker is paid Rs.4625 for =(6/1110)×(4625) days

=25 days

Answer:

(-14) (4/3k) = -56k/3

Step-by-step explanation:

42/-3 = -14

j/j = 1, so j "cancels"

4k²/3k = 4/3k

Answer: she bikes for 10 hours and runs for 6

Step-by-step explanation: suppose that x equals the amount of hours she runs and y equals the amount of hours she bikes.

6x+ 18y=216

x+y=16

(This is your system of equations)

(Starting with the second equation, x+y=16)

y=-x +16 (move x to the other side by transposition)

Now that you have something that equals Y you plug it in to the other equation:

6x+18(-x+16)=216

(Start solving)

6x-18x+288=216 (used distributive property)

-12x+288=216 (Combine like terms)

-12x=-72 (use transposition again)

x=6 (divide to get x by itself)

Now you plug in the value of x into your equation for the value of “y”, y=-x+16,

Y=-6+16 (plugged in the value of x)

Y=10 (solved the equation -6+16)

Answer:

66m*2

Step-by-step explanation:

2(20m + 13m)

= 66m*2

Answer:

66 m

Step-by-step explanation:

Since you are adding all the sides, you multiply 20x2 because there are two sides. Then you multiply 13x2 because 6 plus the missing number in the bottom right corner is equal to 7. The answer that you get from the multiplications, you add them and you have your perimeter.

Answer:

Area of circle - Area of square

radius of circle is 8m

side of squre os 12m

Step-by-step explanation:

Area of circle is pie r^2

22/7 × 8 × 8

22/ 7 × 64

= 201.14m^2

Area of square is side ^2

12 ×12

= 144m^2

hence 201.14 - 144

= 57.14m^2 is the area of shaded figure

Answer:

3t

Step-by-step explanation:

7t-3t+4t-5t

Combine like terms

7t -3t = 4t and substitute back into the expression

4t +4t -5t

4t+4t = 8t and substitute back into the expression

8t - 5t
