Answer:

The Volume of Cone is V=1/3hπr².

V = 1/3 × h × π × r²

V = 1/3 × 12 × 3.14 × 5cm

V = 1/3 × 12 × 15.7

V = 4 × 15.7

V = 62.8cm³ ANS

→ we need to find the radius so r = d/2 = 10/2 = 5cm

Answer:

C = 0.5t + 12. Independent variable is t and the dependent variable is C.

Step-by-step explanation:

$12 is constant, and then $0.50 is multiplied to the amount of toppings (t). So C= 0.5t + 12 and the cost is dependent on the amount of toppings.

Answer:

C = 0.5t +12

Answer:

u = 143º

Step-by-step explanation:

Sum of angles in a triangle is 180

The unknown angle IN the triangle

x + 90 + 53 = 180

x + 143 = 180

x = 37º

x and u are supplementary angle which total 180

u + 37 = 180

u = 143º

Answer:

[tex]x=37.4[/tex]

Step-by-step explanation:

In an right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse (a/h).

Therefore, we have the following equation:

[tex]\cos 68^{\circ}=\frac{14}{x},\\x=\frac{14}{\cos 68^{\circ}}\approx\boxed{37.4}[/tex]

Answer:

3^3 x 3.14

9 x 3.14 = 28.26

28.26  x 2 = 56.52

2 x 3.14 x 3 = 18.84

18.84 x 10 = 188.4

Now lets add all given areas:

56.52 + 188.4 = 244.92 m^2 for question 1

4 x 3.14 x 12^2

4 x 3.14 x 144 = 1,808.64 cm^2 is your answer for question 2

14^2 x 3.14

196 x 3.14 = 615.44

3.14 x 14 x 33 = 1450.68

1450.68 + 615.44 = 2,066.12 cm^2 is your answer for question 3 I think

Answer:

k = 9/5

Step-by-step explanation:

In y=k/x^2 replace x with (-3) and y with (1/5); then calculate k:

              k

(1/5) = ----------

           (-3)^2

         1           k

or   ------- = ----------

          5          9

Solving for k through cross-multiplication, we get

5k = 9, or k = 9/5

The value of k is,

⇒ k = 9/5

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

it is known that point (-3, 1/5) belongs on graph y=k/x²

Hence, The given point satisfy the equation as;

⇒ y = k / x²

⇒ 1/5 = k / (- 3)²

⇒ 1/5 = k / 9

⇒ k = 9/5

Thus, The value of k is,

⇒ k = 9/5

Answer:

TR = 3 units

Step-by-step explanation:

Recall: tangents drawn from an external point are equal to each other

Therefore,

TR = UR

We need to find UR first

Thus:

UR = PR - UP

PR = 12 (given)

UP = SP = 9 (tangents drawn from an external point are congruent)

UR = 12 - 9

UR = 3 units

Therefore,

TR = UR = 3

TR = 3 units

Answer:

[tex]XY : WX = 1.39[/tex]

Step-by-step explanation:

Given

[tex]RS = 18; ST = 25; TR = 11[/tex]

Required

Which is closest to [tex]XY : WX[/tex]

From the question, we understand that: [tex]\triangle RST[/tex] and [tex]\triangle WXY[/tex] are similar.

This means that, the following sides are similar:

[tex]RS \to WX[/tex]

[tex]ST \to XY[/tex]

[tex]TR \to YW[/tex]

So:

[tex]XY : WX = ST : RS[/tex]

This gives:

[tex]XY : WX = 25 : 18[/tex]

Express as fraction

[tex]XY : WX = \frac{25 }{ 18}[/tex]

[tex]XY : WX = 1.39[/tex] --- approximated

2.7

Step-by-step explanation:

Using PEMDAS you do 2-1.1 first which is is 0.9 then you multiply it by 4 you get 3.6 and then you subtract that by 6.3 and you get 2.7

Answer: 2.7

Use PEMDAS method.

Answer:

A line parallel has the same slope, so -3

The slope of the line that is parallel to line f is -3.

The given line f has a slope of -3.

We need to find the slope of the line that is parallel to line f.

The slope of parallel lines. The slope of parallel lines is equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as [tex]m_{1}[/tex], [tex]m_{2}[/tex] then we have [tex]m_{1}=m_{2}[/tex].

So, the slope of the parallel line=-3

Therefore, the slope of the line that is parallel to line f is -3.

Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.

Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.

Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

The variables are:

And the proportional relation that relates them is:

y = $7*X

The only information that we know is that Tiya earns $7 per hour, so the only variables that we can use are money and time.

The independent variable will be time, because she can decide how much time can she work. The dependent variable is money, because how much she earns depends on how many hours she works.

The ordered pairs are of the form (number of hours, money).

Some examples for this case are:

We define the variables.

Because she wins $7 per hour, the proportional equation will be:

y = $7*x

Answer:

517.2

Step-by-step explanation:

It has sides you're not seeing so don't forget those.

You need to find the area of the front, back, two sides, and bottom

Front & back:

6*5.2* 1/2

31.2/2 = 15.6 for each

Sides:

27*6 = 162 each

Bottom:

6*27 = 162

162+162+162+15.6+15.6= final answer

Answer: B

Step-by-step explanation:

First, you do 5.2 times 6 divided by two which is 15.6. Now you do 15.6 times two since there are two triangles and get 31.2. Now you do 27 times 6 times two and get 324 + 31.2 = 355.2. Lastly, you do 27 times 6 to get 162. 162+355.2 = 517.2
