Answer:

simple

Step-by-step explanation:

The radius of the wheel can be solved from its given speed and RPM.

Converting km/h to m/min

speed = 66 km / h = 66000 m / 60 min

speed = 1100 m / min

Converting one revolution to meters

1100 m / min = 500 revolution / min ... (given)

500 revolutions = 1100 m

1 revolution = 2.2 m

Solving for the radius of the wheels in meters

1 revolution = 2.2 m

2 * pi * radius = 2.2 m

radius = 2.2 m / 2 * pi

radius = 1.1 m / pi

radius = 0.3501 m

Answer:

x = 11

Step-by-step explanation:

3 x 11 = 33

33-5 = 28

x = 11

Answer:

10

Step-by-step explanation:

Given

h(x) = 3x - 5

h(x) = 25

3x - 5 = 25

3x = 25 + 5

3x = 30

x = 30 / 3

x = 10

Answer:

4 over 5 (4/5)

Step-by-step explanation:

Its extremely simple. You need to start from the lower point, and count up until you get to the same lime as the other point. Starting from the lower point, you count up 4 to get on the same line. Then, since its on the right, you count to the right 5, till you get to the dot, and you get 4/5. All you have to do is just count

Answer:

26.5 units

Step-by-step explanation:

The height of the ball at any time t is given by :

[tex]h(t)= -16t^2 + 40t + 1.5[/tex] ...(1)

We need to find the maximum height of the ball.

For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]

i.e.

[tex]\dfrac{d( -16t^2 + 40t + 1.5)}{dt}=0\\\\-32t+40=0\\\\t=\dfrac{40}{32}\\\\t=1.25\ s[/tex]

Put t = 1.25 in equation (1) to find the maximum height.

So,

[tex]h(t)= -16(1.25)^2 + 40(1.25) + 1.5\\\\=26.5\ units[/tex]

So, the maximum height reached by the ball is 26.5 units.

Answer:

608,900

Step-by-step explanation:

it is hard to explain, but here is the answer

The number 608,897 to the nearest tens is 608,900.

Rounding off is the method of simplifying a number to the next closest number by maintaining it's value.

Rounding can be done for decimals as well as whole numbers. Rounding can be done to different place values like tens, hundreds, and in decimals, tenths, hundredths, etc. can be done.

The given number is 608,897.

We have to round this to the nearest ten.

For that, we have to consider the digits in the place values ones and tens.

The digit in the ones is 7. Replace it with 0.

Since the digit in the ones is greater than 5, the digit in the tens column get increased by 1. So 9 in the tens column become 10. By keeping 0 at the tens column 1 is given to the next place value, hundreds. So the digit on the hundreds value which is 8 get increased by 1 and become 9.

Thus the number 608,897 is rounded to 608,900.

Hence the number 608,897 can be rounded off to the nearest tens as 608,900.

[tex]\frac{35}{54}[/tex]

Step-by-step explanation:

When multiplying two fractions, you multiply across always. We have two fractions :

7/9 and 5/6

So multiply across :

[tex]\frac{7 * 5}{9 * 6}[/tex]

[tex]\frac{35}{54}[/tex]

Answer:

n = 64

Step-by-step explanation:

3/4n - 8 = 5/8n

-8 = 5/8n - 6/8n

-8 = -1/8n

-n = -64

n = 64

The unknown number is 64.

Important information:

[tex]\dfrac{3}{4}[/tex] of a number [tex](n)[/tex] is [tex]\dfrac{3}{4}n[/tex].

Difference between [tex]\dfrac{3}{4}[/tex] of a number [tex](n)[/tex] and 8 is [tex]\dfrac{3}{4}n-8[/tex].

[tex]\dfrac{5}{8}[/tex] of the number is [tex]\dfrac{5}{8}n[/tex].

Using the given information form a linear equation.

[tex]\dfrac{3}{4}n-8=\dfrac{5}{8}n[/tex]

Now, solve the equation.

[tex]\dfrac{3}{4}n-\dfrac{5}{8}n=8[/tex]

[tex]\dfrac{6n-5n}{8}=8[/tex]

[tex]\dfrac{n}{8}=8[/tex]

Multiply both sides by 8.

[tex]n=64[/tex]

Therefore, the unknown number is 64.

Answer:

C

Step-by-step explanation:

The 3 triangles are all similar.

Using the 2 inside then the ratios of corresponding sides are equal, that is

[tex]\frac{x}{3}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )

x² = 36 ( take the square root of both sides )

x = [tex]\sqrt{36}[/tex] = 6 → C

Answer:

C) x = 6

because this is a right triangle

=> we have:

(12² + x²)(3² + x²) = (15x)²

<=> 1296 + 153x² + x⁴ = 225x²

<=> x⁴ - 72x² + 1296 = 0

<=> (x² - 36)² = 0

<=> x² = 36

=> x = 6

131m

Step-by-step explanation:

274.5÷4.5=61

4.5m×2=9m

61m×2=122

122m+9m=131m

Answer:

Perimeter = 131 m

Step-by-step explanation:

Area=Length x Width so:

274.5 = 4.5 x Width

Width = 274.5/4.5 = 61 m

Perimeter = 2 Widths + 2 Lengths so:

Perimeter = 2(4.5)+2(61 )= 131 m
