Step-by-step explanation:

The angle formed by the clock is its degree measure

The angle formed by the hands of the clock when practice starts is 30 degrees

The current angle is given as:

Angle = 90 degrees

The basketball practice starts at:

Practice = 2 hours earlier

An hour in time represents 30 degrees.

So, the angle formed when the practice starts is

Angle = 90 degrees - 2 * 30 degrees

Evaluate

Angle = 30 degrees

Hence, the angle formed by the hands of the clock when practice starts is 30 degrees

Answer:

m∠G = 60°

Step-by-step explanation:

This is a kite, so its angles sum to 360 degrees. Write an equation adding all of the angles and make them equal to 360:

m∠H + m∠F + m∠E + m∠G = 360

90 + 150 + m∠E + m∠G = 360

Since this is a kite, m∠E = m∠G, so the equation can be represented as:

90 + 150 + 2(m∠G) = 360

Finally, solve by isolating m∠G:

2(m∠G) = 120

m∠G = 60°

The wedge is an illustration of arc lengths, and Tyler's ledge is larger than Priya's wedge

From the question, the arc length of Tyler's wedge is:

L = 12 cm

For Priya's wedge, we have the following highlights:

Radius = 9 cm

Angle = 60 degrees i.e. the angle when a circle is divided into 6 sectors

Priya's arc length is then calculated as:

[tex]L = \frac{\theta}{360} * 2\pi r[/tex]

This gives

[tex]L = \frac{60}{360} * 2 * 3.14 * 9[/tex]

Evaluate

L = 9.42

By comparing the arc lengths 9.42 and 12 cm, we have 12 cm > 9.42 cm

Hence, Tyler's ledge is larger than Priya's wedge

Answer:

So first you have to make all the denominaters (bottom #s) the same so we would get 12/20-8/20+5/20 and you would solve this to equal 9/20 and to divide it by 1/6 would equal 2 7/10.

Answer:

  4.8 m

Step-by-step explanation:

The area of a rectangle is the product of length and width. This relation can be used to find any of the dimensions when the other two are known.

__

Here, we know area and length, so we can find width.

  A = LW

  W = A/L = (29.76 m²)/(6.2 m) = 4.8 m

D. 16 + 72n and (2 + 9n) (8)​

Step-by-step explanation:

Select the equivalent expressions.

Distribute to find the equivalent expressions:

A.

71 - 9y and (7x - y) (9)

71 - 9y = 9(7x) + 9(-y)

71 - 9y = 63x - 9y

Not equivalent

B.

5(3t - 6) and 15 - 30

5(3t) + 5(-6) = 15 - 30

15t - 30

Not equivalent (it's missing the variable - t)

C.

4(6a + 86) and 10a + 126

4(6a) + 4(86) = 10a + 126

24a + 344 = 10a + 126

Not equivalent

D.

16 + 72n and (2 + 9n) (8)​

16 + 72n = 8(2) + 8(9n)

16 + 32n = 16 + 72n

Equivalent

Therefore the correct answer is D

According to question we have equations

Find the number of students by substitution

Find the number of apples

Answer:

14 apples

Step-by-step explanation:

Let x = number of students

Let y = total number of apples

Create a system of equations with the given information.

Equation 1

If she gave each student 3 apples, she would have 2 apples left:

⇒ y - 3x = 2

Equation 2

If she gave each students 4 apples each she would be 2 short:

⇒ y - 4x = -2

Rewrite Equation 1 to make y the subject:

⇒ y = 2 + 3x

Substitute this into Equation 2 and solve for x:

⇒ (2 + 3x) - 4x = -2

⇒ 2 + 3x - 4x = -2

⇒ 2 - x = -2

⇒ -x = -4

⇒ x = 4

Substitute the found value of x into the rewritten Equation 1 and solve for y:

⇒ y = 2 + 3(4)

⇒ y = 2 + 12

⇒ y = 14

Therefore, Mrs Reyes had 14 apples.

Answer:

SA = 527.52 cm²

Step-by-step explanation:

Cone SA = πr(r + √(h² + r²))

Find h

Step 1. Create a right triangle with the radius (attached image)

Step 2. Pythagorean Theorem

a² + b² = c²

7² + b² = 17²

b² = 289 - 49

b = √240

b or h = 4√15

Solve for SA

SA = πr(r + √(h² + r²))

SA = 3.14 · 7 · (7 + √(4√15² + 7²))

SA = 21.98(7 + √(240 + 49))

SA = 21.98 (7 + 17)

SA = 527.52 cm²

Answer:

0 ≤ y ≤ 7

Step-by-step explanation:

Hey there! :)

Please see an explanation for better understanding, and let me know if you have any questions!

Range in Function means set of all y-values. We know by the graph that y-value is a vertical value while x-value is horizontal value. From the graph, we have y-axis which is vertical line and x-axis which is horizontal line.

For this question, I would like you to focus on y-value instead, at best, only. That is because we are finding the range, as said above that range is the set of all y-values.

To find the range in graph, first, you must understand that range starts from minimum point/value to maximum point/value. Therefore, we will have to find y-values for both points and combine the interval.

From the graph, we see that there are two points given which are (-6,0) and (9,7). Since (-6,0) is the minimum point because below y = 0, there exists no values. On the other hand, (9,7) is our maximum point because above y = 7, there exists no values.

Focus only y-values, for both points, we have y = 0 and y = 7. Since range is minimum < y < maximum - for opened dots of both points or minimum ≤ y ≤ maximum - for closed dots for both points.

In case if you don’t know what opened dots and closed dots are. Opened dots are white dots while closed dots are colored dots, usually dark ones.

Thus, from the y-values of both point, our range is 0 ≤ y ≤ 7

'12 feet'

Step-by-step explanation:

Of these threee measurements, '12 feet' is closest to the height of a house.

Using a geometric sequence, it is found that:

a) The explicit formula is: [tex]a_n = 250000(2.1)^{n-1}[/tex].

b) The value of her collection 9 years after she started tracking is of $94,557,148.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

Item a:

Three years ago, her collection was worth $250,000, hence the first term is [tex]a_1 = 250000[/tex].

In two years, the collection was valued at $1,102,500, hence the common ratio is:

[tex]q^2 = \frac{1,102,500}{250,000}[/tex]

[tex]q^2 = 4.41[/tex]

[tex]q = \sqrt{4.41} = 2.1[/tex].

Hence, the explicit formula is:

[tex]a_n = 250000(2.1)^{n-1}[/tex]

Item b:

[tex]a_9 = 250000(2.1)^{9-1} = 94557148[/tex]

The value of her collection 9 years after she started tracking is of $94,557,148.
