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.

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: 30 seconds

Step-by-step explanation:

From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.

The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:

10 = 10, 20, 30, 40, 50 ...

15 = 15, 30, 45, 60, 75 ....

We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.

They'll both flash again at same time in 30 seconds.

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

3t

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

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:

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:

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

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

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: 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:

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: 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:

A rational number is any integer, fraction, terminating decimal, or repeating decimal. The square root is not rational.

good luck, i hope this helps :)
