Answer:

A. 1

Step-by-step explain

You put the number in order and it will be only the 6 from the 6-10.

The value that should be placed in the second column for the range 6-10 is 1. Thus, the correct option is A.

The frequency is the number of times an event happens. Therefore, frequency is the number of repetition of a digit or an event.

For the given data set 3, 12, 25, 2, 3, 6, 17, 17, 15, 13, 20, 12, 21, 18, 19. The frequency table can be made as,

1 - 5  ⇒  3

6 - 10  ⇒  1

11 - 15  ⇒  4

16 - 20  ⇒  5

21 - 25  ⇒  2

Hence, the value that should be placed in the second column for the range 6-10 is 1. Thus, the correct option is A.

Answer:

A

Step-by-step explanation:

The easiest way to do this problem is to find out how far he can go in 1/2 hour.

If he goes 3 miles in 1 hour

he will go 3/2 miles in 1/2 hour

=============

Now just add this onto the distance travelled in 1 hour.

3 + 3/2 = 3 + 1.5 = 4.5

The answer is A

The answer can be obtained another (perhaps better ) way.

Set up a proportion

1 hour gives 3 miles

1.5 hours gives x

1/1.5 = 3/x                Cross multiply

1*x = 1.5 * 3             Combine    

x = 4.5 miles

Step-by-step explanation:

Well if the are is 12ft^2 and the perimeter is 16 ft then the length is 6 ft and the width is 2 ft.

So 6+6+2+2=16

6*2 is 12

Answer:

Step-by-step explanation:

hello,

we can assume that the table is a rectangle

so let's note x , y its length and width, we can write

(1 ) 2(x+y)=16

(2) xy=12

x and y are different from 0 and from (2) we can write

y =12/x we replace it in (1)

x+12/x=16/2=8

[tex]<=> x^2+12=8x\\<=> x^2-8x+12 = 0\\<=> x^2 -2x-6x+12=0\\<=> x(x-2)-6(x-2)=0\\<=> (x-6)(x-2)=0\\<=> x = 6 \ \ or \ \ x=2[/tex]

for x = 6 y = 2

for x = 2 y = 6

so the dimensions of the table is 2ft x 6ft

(0,-2) = No

(-5,0) = Yes

(8,0)  = Yes

(-9,-6) = No

Step-by-step explanation:

It says "solution to y = 0" so then look at the y-axis which is the second number in parenthesis.

Ex: (0, -2), y is -2 and x is 0.

Just make sure the second number is equal to 0, if not, then that is not the solution.

Answer: The correct answer is option 4;

A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.

Step-by-step explanation: A simple check for the result of each set of dimensions would give the correct answer.

The volume of a right triangular prism is derived as follows;

Volume = 1/2 * b * h * l

Where, b is the base of the triangle, h is the vertical height of the triangle and l is the length of the prism.

Note that the area of the right triangle is denoted by 1/2 * b * h, and multiplying this result by the length of the prism gives the entire depth or volume of the triangular prism. Let us examine the dimensions one after the other;

(1) A triangular prism. The triangular base has a base of 7 metres and height of 9 metres. The height of the prism is 6 metres.

Volume = 1/2 * 7 * 9 * 6

Volume = 189 cubic metres

(2) A triangular prism. The triangular base has a base of 6 metres and height of 13 metres. The height of the prism is 5 metres.

Volume = 1/2 * 6 * 13 * 5

Volume = 165 cubic metres

(3) A triangular prism. The triangular base has a base of 11 metres and a height of 8 metres. The height of the prism is 8 metres.

Volume = 1/2 * 11 * 8 * 8

Volume = 352 cubic metres

(4) A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.

Volume = 1/2 * 10 * 9 * 8

Volume = 360 cubic metres

1 = ( 1000 x 0.50 = 500 (+1000) ) = 1500= $1500

3500+1500 = $5000

Answer:

A sequence is defined as an arrangement of numbers in a particular order. On the other hand a series is defiend as the sum of the elements of a sequence!

Answer:

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

Step-by-step explanation:

In a triangle, the sum of all inside angles must be 180 degrees.

In this question:

The inside angles are: x, x + 50 and 180 - 3x.

Then

x + x + 50 + 180 - 3x = 180

2x - 3x = -50

x = 50

So

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

Answer:

-15,20

Step-by-step explanation:

I do not know how to explain how I did it lol :) , but I am very sure that it is correct.

I hope this help you :)

Answer:

-15, 20

Explanation:

To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.

Take a look at the sequence given:

5, -5, 10, -10, 15,...

Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.

5 - first term

-5 - second term

5 ? ? = -5

5 × -1 = -5

So, this means the sequence multiplied negative one by the first term to get the second term. Therefore, the pattern should be 'multiply negative one' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.

5, -5, 10, -10, 15,...

5 × -1 = -5 [correct; provides the next term]

-5 × -1 = 5 [incorrect; does not provide the next term]

10 × -1 = -10 [correct; provides the next term]

-10 × -1 = 10 [incorrect; does not provide the next term]

According to the calculations shown above, the pattern we have identified ('multiply negative one') only works on every other term. Therefore, we must figure out the rest of the pattern for the remaining terms. To do that, identify what basic operation and number must be applied.

-5 - second term

10 - third term

-5 ? ? = 10

-5 × -2 = 10

So, this means the sequence multiplies negative two every other term. Therefore, the pattern should be:

multiply by negative one, multiply by negative two

However, to be sure the pattern we have identified is correct, apply it to the sequence.

5 × -1 = -5 [correct; provides the next term]

-5 × -2 = 10 [correct; provides the next term]

10 × -1 = -10 [correct; provides the next term]

-10 × -2 = 15 [correct; provides the next term]

Now that we have identified the correct pattern, let's apply it to the last term to find the next two terms.

5, -5, 10, -10, 15....

15 × -1 = -15

-15 × -2 = 20

Therefore, the next two terms in the sequence is -15, 20.

Answer:

A = 60 cm²

Step-by-step explanation:

Finding BC using Pythagorean Theorem:

=> [tex]c^2= a^2+b^2[/tex]

=> [tex]13^2 = a^2+5^2[/tex]

=> 169-25 = [tex]a^2[/tex]

=> [tex]a^2[/tex] = 144

Taking sqrt on both sides

=> BC = 12

So,

BC = CD = 12

=> BD = BC+CD

=> BD = 12+12

=> BD = 24

Now, The area:

=> Area of a Triangle = [tex]\frac{1}{2} (Base)(Height)[/tex]

Where BASE = 24, HEIGHT = 5

=> A = 1/2(5)(24)

=> A = 1/2(120)

=> A = 60 cm²

Step-by-step explanation IN triangle abc,

AC² = AB² + BC² (Phythogoras theorem)

13² = 5² + BC²

169 - 25 = BC²

144 = BC²

BC² = 144

BC = 12 (APPLAYING SQAURE ROOT)

Then in triangle ADC,

AD² = AC² + CD²

AD² = 13² + 12² (CD = BD - BC)

AD² = 169 + 144

AD = 17cm (aprox.)

Therefore area of triangle abd = 1/2× length × side = 1/2× 5 ×24 = 5 × 12 = 60cm

Answer:

27

Step-by-step explanation:

180-153=b

b=27

Answer:

B) 27

Step-by-step explanation:

Because 153 and b are a linear pair, their angle measures must add up to 180 degrees. Therefore:

153+b=180

b=180-153

b=27

Hope this helps!

Answer:

B and E are the correct answers.

Step-by-step explanation:

By using the slope formula of y₂₋y₁ / x₂₋x₁ you can find out that the slope is ₋7/4.

Next pick a point to put into point-slope form.

Point-slope form is y₋y₁ = m(x₋x₁) where y₁ and x₁ are a point on the graph and m is the slope.

Substitute both points into the formula (separately) to get B and E as your answers.

Answer:

The numbers missing are 8 and 7.

Step-by-step explanation:

First you need to find a pattern in the numbers. You will notice that the pattern is add 3, subtract two. This is because, to get from 4 to 7, you add three, and to get from 7 to 5, you subtract 2.

When you apply that pattern, you find the missing numbers.
