Answer:

60

Step-by-step explanation:

First, divide 120 by two and get 60. Now do 120-60 to get 60. Set up proportion

60/x = x/60.

Cross multiply

x^2 = 3600

and now find the square root of 3600

Answer:

C = pi d

C = 3.14 × 70

C = 219.8 inches

A = pi r²

A = 3.14 × 1,225

A = 3,846.5

Answer:

The value of x is 21 .

Step-by-step explanation:

We are given that x varies directly as y

--- A

We are given that x = 7 and y = 28

Substitute the values in A

7 = 28k

Now equations becomes :  

y = 84

Hence The value of x is 21 .

Answer:

9.42 m

6.28m

Step-by-step explanation:

to determine the distance walked, calculate the circumference of the circular pool

circumference of a circle = πD

π = 3.14

D = diameter

3 x 3.14 = 9.42 m

Difference in circumference =  π( diameter of bigger circle - diameter of smaller circle)  

diameter of smaller circle = 5 x 2 = 10

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x ( 12 - 10) = 6.28

Answer:

2x + 20 = -60

-20           -20

2x = -80

Divide by 2 on both sides.

X = -40

Answer:

-40

Step-by-step explanation:

2(x + 10) = -60

step 1 distribute the 2 to the x and 10

2 * x = 2x

2 * 10 = 20

we now have 20 + 2x = -60

step 2 subtract 20 from each side

20 - 20 cancels out

-60 - 20 = -80

we now have 2x = -80

step 3 divide each side by 2

2x / 2 = x

-80 / 2 = -40

we're left with x = -40

Step-by-step explanation:

The path followed by the ball as a function of time is given by :

[tex]h=-16t^2+vt+h[/tex]

Where

v is initial velocity and h is initial height,

v = 4.3 cm/s = 0.043 m/s and h = 14 cm = 0.14 m

The equation becomes,

[tex]h=-16t^2+0.043t+0.14[/tex] ....(1)

It is a quadratic equation,

t = 0.095 s

Put the value of t in equation (1).

[tex]h=-16(0.095)^2+0.043(0.095)+0.14\\\\h=-0.000315\ m[/tex]

or

h = -0.00103 ft (negative sign shows height is in negative direction)

Answer:

Area of the sector = 47.52π

Step-by-step explanation:

Area of the sector of the circle;

A = ∅ / 360 * πr²

We know that;

∅ = 120

r = 12

So now we can substitute;

A = (120 / 360) * π(12)²

A = 0.33 * 144π

A = 47.52π

Answer:

it means less than or equal to :)

Step-by-step explanation:

Answer:

To do this question, you need to put the numbers in least to greatest. Greatest to least will not work and will be incorrect.

It will be:

-3, -1, 0, 1, 5, 6, 7, 8, 10, 13

Now you have to cancel each number out from each end.

You will get the numbers:

5, and 6.

You have to find the average of this so:

5 + 6 = 11

11 ÷ 2 = 5.5

So the answer is 5.5.

Answer:

5.5

Step-by-step explanation:

First you would rearrange the numbers from smallest to biggest or vice versa then you cancel out equal number of numbers on both sides until you get to the middle. If it's an even amount of numbers, like 10, then there will be two in the middle instead of one so in that case you would add the two of them and then divide by two.

For example, -3, -1, 0, 1, 5, 6, 7, 8, 10, 13

you would cancel out until you get to the middle which would leave you with 5 and 6 so you add them and divide by two to get 5.5.

Answer:

what is the formulae for finding a circle

Given:

A line passes through the points (-3,3) and (3,5).

To find:

The equation of the line by using point slope form, then rewrite the equation in slope-intercept form.

Solution:

It is given that the line passes through the points (-3,3) and (3,5). So, the slope of the line is:

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

[tex]m=\dfrac{5-3}{3-(-3)}[/tex]

[tex]m=\dfrac{2}{6}[/tex]

[tex]m=\dfrac{1}{3}[/tex]

The point slope form of a line is:

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

Where, m is the slope.

The point slope form of the given line is:

[tex]y-3=\dfrac{1}{3}(x-(-3))[/tex]

[tex]y-3=\dfrac{1}{3}(x+3)[/tex]

The point slope form of the given line is [tex]y-3=\dfrac{1}{3}(x+3)[/tex].

We need to rewrite this equation in slope intercept form, i.e.,  [tex]y=mx+b[/tex], where m is slope and b is y-intercept.

The above equation can be rewritten as:

[tex]y-3=\dfrac{1}{3}(x)+\dfrac{1}{3}(3)[/tex]

[tex]y-3=\dfrac{1}{3}(x)+1[/tex]

[tex]y=\dfrac{1}{3}(x)+1+3[/tex]

[tex]y=\dfrac{1}{3}(x)+4[/tex]

Therefore, the slope intercept form of the given line is [tex]y=\dfrac{1}{3}(x)+4[/tex].

Hi there!

[tex] \large{lim_{x \longrightarrow 3}( - 5 {x}^{2} - 2x + 4)}[/tex]

Simply substitute x = 3 in the expression.

[tex] \large{ - 5 {(3)}^{2} - 2(3) + 4} \\ \large{ - 5(9) - 6 + 4} \\ \large{ - 45 - 6 + 4} \\ \large{ - 47}[/tex]

Questions can be asked through comment.

Furthermore, limit is like substituting a value. Note that limit is about an approaching value. This is a basic limit.

Answer:

its Ifa point is on the perpendicular bisector of a segment, then it is proportional from the endpoints of the segment.

Answer:

No

Step-by-step explanation:

To determine if the point is a solution to either of the inequalities, substitute the variables with the point given. When y<-3.x+4 is substituted with (0,4), the inequality becomes 4<4, which proves that the point is inapplicable to the first inequality. Therefore, you do not need to continue to check its applicability with the second inequality.

Answer:

Answer:

$3.60

Step-by-step explanation:

8 apples × 150 grams

1200 grams

1 kilogram = 1000 grams

x. = 1200 grams

X = 1.2 kg

1kg = $3.00

1.2kg =$3.6

The cost of 8 apples that have weight 1.2 kilograms is,

⇒ $3.60

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Amy buys eight apples that each weigh 150 grams.

And, She notices that they are on sale for $3.00 per kilogram.

Now,

Total weight of the apples is,

⇒ 8 × 150 grams

⇒ 1200 grams

⇒ 1.2 kilograms

Since, She notices that they are on sale for $3.00 per kilogram.

Hence, The cost of 8 apples that have weight 1.2 kilograms is,

⇒ $3.00 × 1.2

⇒ $3.60

Thus, The cost of 8 apples that have weight 1.2 kilograms is,

⇒ $3.60
