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

Answer:

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:

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.

Answer:

7/12

Step-by-step explanation:

the least common denominator is 12

4 goes into 12 three times so you multiply both numbers in 3/4 by three

3/4 = 9/12

6 goes into 12 twice so multiply both the 1 and 6 by two

1/6 = 2/12

so the equation becomes 9/12 - 2/12

subtract the numerators

9-2= 7

7/12 can't be simplified any farther so that's the final answer

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:

154

Step-by-step explanation:

The expression is  [tex]f(x)=4x^2-7x+7[/tex] and we know that  [tex]f(x)=f(7)[/tex]. Therefore, you will have to substitute x with 7.

Calculations:

[tex]f(x)=4x^2-7x+7[/tex]

[tex]f(7)=4(7)^2-7(7)+7[/tex]

[tex]4(49)-49+7= 154[/tex]

Answer:

I think that you need to plug 7 in to the x's

Step-by-step explanation:

Yes it looks very weird, but if you don't think that is right, Use the 7 for the F's.

Step-by-step explanation:

We want to find the graph of a system of inequalities. We want to select the correct option, but sadly is really hard to interpret the given text, so I will add a graph of the system at the end.

The system is:

To graph these we first need to graph the two lines:

y =-3x + 1

Is a line with a negative slope that passes through the y-axis at y = 1.

Because here we have y ≤ -3x + 1 we know that y must be equal or smaller than the line, thus we need to shade below the line, and because y can be equal to any value in the line we need to use a solid line.

For the other equation:

y = (1/2)*x+ 3

We have a positive slope and this line intercepts the y-axis at y = 3.

Similar as before, here we have y ≤ (1/2)*x+ 3 so the shaded area will be below the line and the line must be solid.

With this in mind, we can graph the system, and you can see it below:

Answer: 20°, 50° and 90°

Step-by-step explanation:

From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio ​2:​5:9.

The exact angle measures will then be:

= 2/(2+5+9) × 160°

= 2/16 × 160°

= 20°

= 5/(2+5+9) × 160°

= 5/16 × 160°

= 50°

= 9/(2+5+9) × 160°

= 9/16 × 160°

= 90°

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
