How to work out the missing sides?

Answer:

80π feet/ second.

Step-by-step explanation:

Angular velocity of a point = 10π radians per second

Radius of the circle is 8 feet.

We know the formula of angular velocity is

Angular velocity = [tex]\frac{speed}{radius}[/tex]

10π = [tex]\frac{speed}{8}[/tex]

Speed = 80π feet/ second.

Option C is the answer.

Answer: [tex]80\pi\text{ ft/sec}[/tex]

Step-by-step explanation:

Formula : [tex]\text{Speed= Angular velocity x Radius}[/tex]   (1)

We are given that , The angular velocity of a point with radius 8 feet is 10 pi radians per second.

i.e. Radius = 8 feet

Angular velocity = [tex]10\pi[/tex] radians per second.

Then, the speed of the point will be :-

[tex]\text{Speed= }10\pi \times 8[/tex]   [using (1)]

[tex]=80\pi\text{ ft/sec}[/tex]

Hence, the speed of the point [tex]=80\pi\text{ ft/sec}[/tex]

2. 135 grams is your answer

The mass of the baseball is 146 grams.

Mass refers to the weight of an object. It is measured in grams (g) and kilograms (kg).

According to question we have a spherical ball of radius 1.47 inches and density of ball is 11g/cubic inch.

We know that density  = mass/volume                   ...............(i)

Volume of sphere is given by

Volume = 4π(radius)³/3

volume = 4π(1.47)³/3

volume = 13.3057 inches³ By (i)

  mass = density x volume

Answer:

  Square

Step-by-step explanation:

The length of AB is (a+b)-a = b. The length of BC is b-0 = b. So, adjacent sides are the same length. AB has a constant y-value, so is horizontal. BC has a constant x-value, so is vertical.

A figure with horizontal and vertical sides of the same length is a square.

Answer:

B.. skewed left

Step-by-step explanation:

Answer:

Option B. skewed left.

Step-by-step explanation:

In the figure attached maximum frequency of the data is at the 45. Distribution on the right side of the maximum frequency is upto 48 and in the left it is upto 36.

As we can see point 36 is more distant from peak point 45 as compared to point 48.

Therefore, distribution of the data is more in the left than in the right.

Therefore, the shape of this distribution is skewed left.

Option B. skewed left is the correct answer.

Step-by-step explanation:

Is that a lone x on the left hand side? I will assume so.

Let y be the value of the side marked with a ?.

x + 3x + 1 + x + y = 6x + 2     collect the like terms on the left.

5x + 1 + y= 6x + 2                  Subtract 1 from both sides.

5x + 1-1 +y = 6x + 2-1             Combine

5x + y = 6x + 1                        Subtract 5x from both sides.

4x - 20 = 2x + 4 ( subtract 2x from both sides )

Given the point (9,2) is on the graph of f(x), the corresponding point for the function f(-3/4x) is found by multiplying the x-coordinate of the given point by -3/4. This yields the corresponding point (-6.75, 2).

The given point is (9,2). In the function f(-3/4x), the variable is multiplied by the factor -3/4. We apply this factor to the x-coordinate of the given point to find the x-coordinate of the corresponding point in the function f(-3/4x).

Therefore, the x-coordinate of the corresponding point is 9×-3/4 = -27/4 = -6.75. The y-coordinate remains the same because the transformation corresponds only to the x-coordinates of points. So, the corresponding point in the function f(-3/4x) is (-6.75,2).

Answer:

[tex]f(x) = 6x -12[/tex]

Step-by-step explanation:

We must write the function of the line in the form [tex]f (x) = mx + b[/tex]

First calculate the slope m

[tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]y_2 = 18\\y_1 =6\\x_2=5\\x_1=3[/tex]

[tex]m= \frac{18-6}{5-3} = 6[/tex]

Then

[tex]f(x) = 6x +b[/tex]

To have b replaced a point in the function

[tex]f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12[/tex]

Finally the function is

[tex]f(x) = 6x -12[/tex]

ANSWER

[tex]f(x) = 6x - 12[/tex]

EXPLANATION

The given line passes through the points (3, 6) and (5, 18).

The slope of this line given by:

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

We plug in the points to get,

[tex]m = \frac{18 - 6}{5 - 3} = \frac{12}{2} = 6[/tex]

The equation is given by

[tex]y-y_1=m(x-x_1)[/tex]

We plug in the point and the slope to get,

[tex]y - 6 = 6(x - 3)[/tex]

[tex]y - 6 = 6x - 18[/tex]

[tex] y = 6x - 18 + 6[/tex]

[tex]y = 6x - 12[/tex]

Using function notation, we have

[tex]f(x) = 6x - 12[/tex]

Answer:

81% of 403 is.....326.43! (Rounding it to the nearest hundred gives '326')

Step-by-step explanation:

(P= Percentage / X= The number your finding the percentage of...)

Formula : X = P% * X

X = 81% * 403

Converting percent to decimal:

Converting percent to decimal:p = 81% ÷ 100 = 0.81

X = 0.81 x 403

X = 326.43

The answer would be m= -9

Step-by-step explanation:

6(9-m)

You will multiply the 6 with the 9 and -m inside of the parenthesis

54-6m

Divide by -6 on both sides and you will get m= -9

I hope this helps you with this question and have a nice weekend

The equivalent expression to 6(9 - m) is 54 - 6m, determined by applying the distributive property of multiplication over addition and subtraction.

The expression given is 6(9 - m). To identify an expression equal to this, we should look for expressions that maintain the same relationship between the numbers and the variable m. When we distribute the 6 across the parentheses, we multiply 6 by 9, and 6 by -m, resulting in 54 - 6m.

Distributing a number across a subtraction in a parenthesis follows the distributive property of multiplication over addition and subtraction, which allows us to multiply each term inside the parentheses by the number outside.

Answer : 28 units

the shorter side lengths both equal 5 units so that would be 5+5=10

the longer side lengths both equal 9 units so that would be 9+9=18

18+10=28 units

Answer:

The correct answer would be 28 units.

Step-by-step explanation:

the length of the recktangle is 9. There are two sided with 9 so you would add 9+9. The height of the rectangle is 5 and there are two heights. You add 5+5 then you add 18 witch is the sum of 9+9 and you get 28.

Answer:

2541 peanut cookies were sold

Step-by-step explanation:

A system of equations can be written to match the problem description. Let p and c represent the initial numbers of peanut and chocolate cookies, respectively. Then we have ...

p - c = 1820 . . . . Lyn had 1820 more peanut cookies

After selling 35% of her peanut cookies, Lyn had 1-0.35 = 0.65 of the original number left. Likewise, after selling 15% of her chocolate cookies, she had 1-0.15 = 0.85 of the original number left. Then after the sales, the difference in cookie count was 95:

0.65p -0.85c = 95

We only need to know the original number of peanut cookies (p), so we can use Cramer's rule to find the solution for p.

p = (-95 +0.85·1820)/(-0.65+0.85) = 1452/0.20 = 7260

The original number of peanut cookies Lyn had was 7260, so the number she sold is ...

0.35 · 7260 = 2541

_____

Cramer's rule says the solution to ...

ax +by =c

dx +ey =f

Answer:

2541 cookie were sold

Step-by-step explanation:

Sorry, I didn't fully understand your initial question. I'll answer it now.

A quick and easy equation you can always use is y = -x + 2

Put one point on (0, 2) and put another point on (2, 0) (since a slope of 2/2 would cancel out) Then connect the points, and you're done.

Y=-x+2 is an equation that you can use

X=11 because 90-43+5x-8 so 5•11=55-8 =47 90-43=47

Complementary means the angles together would equal 90°. Supplementary means the angles would equal 180°.

Using Complementary angles:

5x-8+43=90 Combine -8 and 43 = 35

5x+35=90

-35 -35

5x=55

8 times 2/3 is 16/3, which when simplified is 5 1/3

To evaluate 8(2/3), you need to multiply 8 by 2/3. The value of 8(2/3) is 16/3.

To evaluate 8(2/3), you need to multiply 8 by 2/3. To do this, you can simplify 2/3 by dividing both the numerator and denominator by their greatest common factor, which is 1.

This simplifies 2/3 to 2/3. Then, multiply 8 by 2/3 to get the final answer.

Therefore, the value of 8(2/3) is 16/3.

Answer:

The slope is 0. However, it is a horizontal line where x=-6.

Step-by-step explanation:

Use the equation m= y2-y1/x2-x1 to get 12--8/-6--6. Two negatives means a positive, so you get 20/0. This means there is no slope, because you cannot divide by 0. However, you notice that both x-values are -6, so you can safely assume that there is a horizontal line where x=-6.

The slope is undefined and the line is vertical and parallel to the y-axis.

Given points (-6, -8) and (-6, 12)

First, the slope of line is

Slope= (change in y/ change in x

         = (12 - (-8)) / (-6 - (-6))

         = (12 +8) / (-6 +6)

         = 20 /0

         = ∞

Since we have a division by zero in the denominator, the slope is undefined.

This indicates that the line is vertical and parallel to the y-axis.

Thus, the slope is undefined.
