What’s the area of the shape

Answer:

251.2 units³ ; 80π units³

Step-by-step explanation:

Volume of a Cylinder is: [tex]V=\pi r^2 h[/tex]

'r' is the radius.

'h' is he height.  

The cylinder has a base radius of 4 units and the height 5 units.

[tex]V=3.14*4^2*5\\V=3.14*16*5\\V= 50.24 * 5\\\boxed {V=251.2}[/tex]

The approximate volume is 251.2 units³.

[tex]V=\pi 4^2*5\\\rightarrow 4^2=16\\V=\pi 16*5\\V=\pi 80\\\boxed {V=80\pi}[/tex]

The exact volume is 80π units³.

Answer: there is 25 in total

Answer:

25

Step-by-step explanation:

3/5 of the list is 15

So the whole list, by proportion, is 15 * 5/3

= 5 * 5

= 25.

Answer: 55.5 (A.)

Step-by-step explanation:

Since angle A = 29 and angle B = 41, angle C must be equal to 110

180 = m<A + m<B + m<C

180 = 29 +41 + m<C

180 = 70 + m<C

110 = m<C

Therefore, side c must be the longest, side b must be the second longest, and side a must be the shortest.

Since side length a, angle A, and angle B are known, one can use the law of sines to solve for side b.

Law of Sines: sinA/a = sinB/b = sinC/c

sinA/a = sinB/b

sin29/41 = sin41/b

b(sin29/41) = sin41

b = 41(sin41)/(sin29)

b = 55.48

b = 55.5

Answer:

A

Step-by-step explanation:

solution is A.

A relation is a function if no x value gives two or more values of y though different values of x may give same value of y.

Answer:

As shown in picture, here is a triangular pyramid whose volume is calculated by:

V = (1/3) x base area x height

  = (1/3) x 20 x 30 x (1/2) x 27

  = (20 x 30 x 27)/(2 x 3)

Answer:

$ 2.55 or less

Step-by-step explanation:

We have if they buy 6 cans of corn and 2 boxes of pasta are priced at $ 15.75 or less, they also tell us that the price of a can of corn is $ 0.50 + half the price of a box of pasta. Let's formulate the equation, let "x" be the cost of the can of corn and "y" be the cost of the box of pasta.

6 * x + 2 * y <= 15.75

x = 0.5 + y / 2

replacing:

6 * (0.5 + y / 2) + 2 * y <= 15.75

3 + 3 * y + 2 * y <= 15.75

5 * and <= 15.75-3

y <= 12.75 / 5

y <= 2.55

replacing in x:

x = 0.5 + 2.55 / 2 = 1.775

Which means that the price of a can of corn is $ 1,775 and for the box of pasta it is $ 2.55 or less.

The answer is 2.55

The value of f(3) = 28.26

Step-by-step explanation:

You have to do is to substitute r = 3 into the function :

[tex]f(3) = 3.14 \times {3}^{2} [/tex]

Answer: 1/35

Step-by-step explanation:

From the question, in a group that has 35 pupils, 11 of the pupils play flute only, 8 play the piano only and 15 play neither instrument.

The probability that a student plays both instruments will be:

Since a third instrument is not mentioned, P(a randomly selected student plays the flute and the piano)

35-15=20,

This is the total students minus the students that play neither instruments.

We then subtract those that play flute only and those that plays piano only from 20. This will be:

20-11-8 = 1

Probability (a student plays both instrument) = 1/35

Answer:

24

Step-by-step explanation:

I will assume this is a right triangle with the information given

a^2+b^2 = c^2 is the Pythagorean theorem

18^2 + b^2 = 30^2

Subtract 18^2 from each side

18^2  - 18^2+ b^2 = 30^2 -18^2

b^2 =900 -324

b^2 =576

Take the square root of each side

sqrt(b^2) = sqrt(576)

b =24

Hello there!

Using the given exponential function of y = 64(0.97)^x, we can tell that it is a decaying exponential function since the rate is less than 1.

The percent of decrease is 3% since 97% of the value is retained per x time.

Hello there!

1. The theoretical possibility of spinning every number out of the 200 spins is approximately to the nearest whole number: 16 times. We found that by dividing 200 by 12 to see how many of each number could fit in 200. 200 divided by 12 equals 16.666 but we can't spin a number 16.6 times so we have to round it to the nearest whole number that stays in the range of 200.

2.

i. The experimental probability of spinning a 1 is 20/200 or 1/10.

ii. The experimental probability of spinning an 8 is 30/200 or 3/20.

iii.  The experimental probability of spinning an 11 is 2/200 or 1/100.

3.  The numbers on the spinner that has a greater experimental probability than the theoretical probability is: 1,2,5,6,8, and 9.

Experimental probabilities:

2: 18/200 or 9/100

5:  17/200

6:  26/200 or 13/100

9:  18/200 or 9/100

The temperature rose, which means it increased. An increase is a positive value, so add a plus sign in front of the number: +4

A decrease is a negative value, so add a negative sign in front of the value: -19

Answers and Step-by-step explanations:

(a)

We need to figure out the amount (or total cost) for each size candy given that they sell a certain number of each box. For the small box, we're given the cost is $4.70, while the large box is $7.00.

We buy x of the small box, so the total amount should be 4.70 * x, or just 4.70x. We buy y of the large box, so the total amount should be 7.00 * y, or just 7y.

So on the table, the top value should be 4.70x, and the bottom value should be 7y.

(b)

The total number of boxes sold was 45 boxes. Remember that x boxes were small and y boxes were large. Since the number of small boxes plus the number of large boxes is equal to the total of 45, we can write:

x + y = 45

(c)

The total cost was $269, so we can write this as the sum of the amounts that we found in part (a):

4.70x + 7y = 269

Answer:

line symmetry & rotational symmetry

Step-by-step explanation:

First given graphs of functions are symmetric about the y-axis while the second is not symmetric about any axis.

If two figures look an exact shape but their size could be small or big then both figures are called similar figures.

When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.

For example, a square with a side of 10 cm and another with a side of 20 cm both square will be similar.

Given two graph of the  any function.

If we look at first graph ;

If we fold it about the y-axis then it will be overlapped so it will be symmetric about the y-axis.

Now,

In the second graph; If we want to fold two portions of this graph such that both parts can overlap each other then it is not possible so it will not symmetric about any axis.

Hence "First given graphs of functions are symmetric about the y-axis while the second is not symmetric about any axis".

Answer:

Yes, it's a right triangle.

Step-by-step explanation:

Use a^2 + b^2 = c^2

10^2 + 12.49 ^2 (its 2 39 square root) = 16^2

100 + 156 = 256

256 = 256

It ended up being equal to one another so yes, it is a right triangle.

Answer: [tex]1460.96ft^3[/tex]

Step-by-step explanation:

You have a cylinder and a cuboid. Find each of these figures' volume individually and add them together.

Cylinder:

height = 4ft

radius = 4ft

[tex]Formula: V=\pi r^2h[/tex]

[tex]V=(3.14)(4ft)^2(4ft)\\V=(3.14)(16ft^2)(4ft)\\V=(3.14)(64ft^3)\\V=200.96ft^3[/tex]

---------------------------------------------------------------------------------------------------

Cuboid:

[tex]Formula: V = l*w*h[/tex]

[tex]V=(15ft)(7ft)(12ft)\\V=1260ft^3[/tex]

------------------------------------------------------------------------------------------------------

Add these two volumes together.

[tex]200.96ft^3+1260ft^3=1460.96ft^3[/tex]

Answer:

C, I believe!

The functions shows the absolute value parent function, F(x) = |x|, vertically stretched is C. G(x) = |x + 14|

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

|x| = x, x ≥ 0.

|x| = -x, x < 0.

This can be measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex(turning point) at (0,0). The range is from the y-coordinate of the vertex to positive infinity.

Vertex (2, 0), Range: {y | 0 ≤ y < ∞}

The parent absolute value function is F(x) = |x|,

If this function is stretched vertically, then the stretched function is of the form.

G(x) = |x + a|

where 0<a<1

Therefore the correct option is C. G(x) = |x + 14|
