Answer:

If the spinner has an even number of spaces,

1

8

. If the spinner has an odd number of spaces, more information is needed.

Explanation:

The answer depends on whether the spinner has an odd or even number of spaces.

If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is

1

2

. This is also the probability of flipping heads on a coin. And so we have:

If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 3 spaces on the spinner, the probability of spinning an odd number will be

2

3

. However, if there are 11 spaces, the probability will be

Step-by-step explanation:

The probability of tossing tails and spinning yellow is 1/6.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Outcomes of tossing a coin= {T,H}

Outcomes of spinner={ R,Y,B}

Now, outcomes are in the event "Toss a tails, spin yellow"

= {TY}

probability of tossing tails and spinning yellow,

= 1/2*1/3

= 1/6

Answer:

1,2,4,8,2

Step-by-step explanation:

For the first blank, it asks you to look at the change in y-value where the x-value changes from 0 to 1. As the y-value goes from 2 to 3 in this space, it is increasing by 1.

For the second blank, it asks you to look at the change in y-value where the x-value changes from 1 to 2. As the y-value goes from 3 to 5 in this space, it is increasing by 2.

For the third blank, it asks you to look at the change in y-value where the x-value changes from 2 to 3. As the y-value goes from 5 to 9 in this space, it is increasing by 4.

For the fourth blank, it asks you to look at the change in y-value where the x-value changes from 3 to 4. As the y-value goes from 9 to 17 in this space, it is increasing by 8.

For the fifth blank, it asks you to find the rate of change for the graph using the information we previously found. As you can see, the rate of change is 2 for this exponential function, as for every x-value increasing by 1, the change in y-value is multiplied by 2. In other words, if you look at the prior answers you can see that 1*2=2, 2*2=4, and 4*2=8, and all of these changes occur while the x-value increases consistently. Therefore, the grow factor is 2 for every interval of 1.

Answer:

Step-by-step explanation:

3x3 plus 7x3 = 30 divided by 2

The area of the quadrilateral is equal to 15 square units.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the quadrilateral in a two-dimensional plane is called the area of the quadrilateral. A quadrilateral is a four-sided polygon with four edges and four corners in geometry.

Given that the quadrilateral has a height of 3 units, the base is 3 units and the upper sides are 7 units.

The area of the quadrilateral is calculated by the formula,

Area = (1/2) x h x (a + b)

Substitute the values in the formula and calculate the area,

Area = (1/2) x 3 x (7 + 3)

Area = (10 / 2) x 3

Area = 5 x 3

Area = 15 square units

Answer:

8 buses

Step-by-step explanation:

So if we want to seperate out a group of objects to a set, we would used division. Our group of objects is basketball fans and our set is a bus.

Now, we divide the group of objects by the set, to find how many sets to fit all the objects.

357/45 = 7.93333

Since we have a mixed number with a fraction, we will always round up. Because we can't have part of a bus and if we round down, we will not have enough buses.

So we need 8 buses

Step-by-step explanation:

since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.

area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2

surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

Answer:

10 Classroom

Step-by-step explanation:

Since,

Custodian clean 2 classrooms in 15 minutes

Then ,

Let's see how many minutes does it takes for a custodian to clean for 1 classroom

To Find that we have to divide the given minutes by the given classroom.

15/2 = 7.5

Hence, in 7.5 minutes a custodian clean 1 classroom

Therefore:

Classroom to minutes:

1 = 7.5

2 = 15

3 = 22.5

4 = 30

5 = 37.5

6 = 45

7 = 52.5

8 = 60

9 = 67.5

10 = 75

11 = 82.5

Hence, we round to the nearest number:

which is 10 classroom in 75 minutes.

For this reason, the answer is about 10 classroom

Answer:

Step-by-step explanation:

Remark

The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.

Formulas

c^2 = b^2 + a^2

Area = 1/2 b * a

Givens

c = 13 feet

a = ?

b = 9 feet.

Answer: 42.2 square feet.

Solution

c^2 = b^2 + a^2

13^2 = 9^2 + a^2

169 = 81 + a^2                 Subtract 81 from both sides.

169 - 81 =81 - 81 + a^2    Combine

88 = a^2                          Take the square root of both sides

√a^2=√88

a = 9.381

Area = 1/2 * 9 * 9.381

Area = 42.21

Rounded to the nearest 1/10 Area = 42.2

Answer:

Radius:

radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.

Diameter:

2 times the radius is the circle's diameter.

Circumference:

The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

The Area is: 84ft

Step-by-step explanation:

multiply "Y" and "X" and you get 78ft.

"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.

"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2

2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.

78+6=84.

Answer:

  (a) 136 ft

  (b) $680

Step-by-step explanation:

You want to know the perimeter length and the cost of tiling around a pool with the L-shape shown.

The sum of horizontal lengths at the bottom of the pool outline is the same as the length at the top.

The sum of vertical lengths at the left of the pool outline is the same as the length on the right.

The perimeter is the sum of horizontal and vertical lengths of the outline, so is ...

  P = 2(40 ft + 28 ft) = 136 ft

The perimeter of the pool is 136 ft.

The cost of tile is found by multiplying the cost per length by the length around the pool.

  tile cost = ($15/(3 ft))(136 ft) = $680

It will cost $680 to put tiles around the edge of the pool.

Answer:

Step-by-step explanation:

Answer is C

Option A doesn't work since angle C doesn't equal to angle K even though they are alternate interior angles which means angle D won't equal to angle L so A-A theorem doesn't work

Option B: they aren't congruent (you can tell just by looking at them) congruent implies that they are identical in side length and angle

Option C: its option C since just by looking at the figure, we know that the side length arent the same, and non of the angles are congruent to each other (excpet angle J since its a vertical angle).

option D: not all triangles are similar
