Step-by-step explanation:

Answer:

Step-by-step explanation:

first step: 0.5 * x

second step: 3* (0.5x) = 1.5x

third step: (1.5x)^2

fourth step: (1.5x)^2 + 1 = 50

(1.5x)^2 + 1 = 50                    Subtract 1 from both sides

(1.5x)^2 = 49                          Take the square root of both sides

1.5x = sqrt(49)

1.5x = +/- 7

1.5x = +7

x = 7/1.5

x = 4.67

1.5x = - 7

x = - 7 / 1.5

x = - 4.67

Answer: 5x9

5 blocks across by 9 blocks high

(Or 9 blocks across and 5 blocks high)

Step-by-step explanation:

3 square blocks = 9 meters,

so 1 square block = 3 meters.

15meters / 3mEnters = 5 square blocks

27meters/ 3meters = 9 square blocks

Step-by-step explanation:

Answer:

(-2 [tex]\frac{1}{2\\}[/tex], -7) would be in 3.

(0,6) would be on the y axis.

(-5,0) would be on the x axis.

Step-by-step explanation

(-2[tex]\frac{1}{2}[/tex],-7) are both negatives since quadrant 1 is positive x and y, quadrant 2 x is positive and y is negative, quadrant 3 is negative x and y, and quadrant 4 is negative x positive y.

(0,6) and (-5,0) is all about which number is x. Every x coordinant comes first.

Answer:

200

Step-by-step explanation:

The factors of 125 are 1, 5, 25, and 125.

The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.

Answer:

How many factors does 125 have? This number has 4 factors: 1, 5, 25, 125 More specifically, shown as pairs... (1*125) (5*25) (25*5) (125*1)

The factors of 200 are:

1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200

so 200 has more factors

Answer:

choice 4) x = 7, y = 7sqrt(3)

Step-by-step explanation:

sin 30 = x/14

0.5 = x/14

x = 7

sin 60 = y/14

0.8660 = y/14

y = 12.12 or 7sqrt(3)

Answer:

400 people attended the air show.

Step-by-step explanation:

Arithmetic sequence:

An arithmetic sequence has the following general equation:

[tex]a_n = a_1 + d(n-1)[/tex]

In which [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term and d is the common difference between the terms.

The sum of the first n terms of an arithmetic sequence is given by:

[tex]S_n = \frac{n(a_1+a_n)}{2}[/tex]

In this question:

First row 1 seat, second 3 seats, 3rd 5 seats and so on.

So we have the following arithmetic sequence:

{1,3,5,7,9,...}

So [tex]a_1 = 1, d = 9 - 7 = 7 - 5 = ... = 2[/tex]

So

[tex]a_n = 1 + 2(n-1)[/tex]

All 20 rows were filled. How many people attended the air show?

Sum of the 20 terms of the progression. So

[tex]S_{20} = \frac{20(1+a_{20})}{2} = 10(1+a_{20})[/tex]

The 20th term is:

[tex]a_{20} = 1 + 2(20-1) = 1 + 2*19 = 1 + 38 = 39[/tex]

So

[tex]S_{20} = 10(1+a_{20}) = 10(1 + 39) = 10(40) = 400[/tex]

400 people attended the air show.

Answer:

67

Step-by-step explanation:

The angle with x in it is a vertical angle to the other one labeled & the right angle put together.

Therefore:

48 + 90 = 2x + 4

Solve for x:

138 = 2x + 4

138 - 4 = 2x + (4-4)

134 = 2x

134/2 = 2x/2

X = 67

Hope this helps! Have a great day!

Answer:

The answer should be 20,000 feet

Step-by-step explanation:

sin 0 =opposite/hypotenuse

sin 30 = AB/AC

sin 30 = 10000/c

c= 10000/sin 30

c=10000/1/2

c=20,000 feet

Answer:

You can create a ratio table by multiplying (or dividing) both quantities in the ratio by the same value to find an equivalent ratio. A ratio table can help you find equivalent ratios in order to solve problems.

Step-by-step explanation:

Step-by-step explanation:

-4x+6<2x

add 4x to both sides

-4x+4x+6<2x+4x

0+6<6x

divide both sides by 6

6/6<6/6x

1<x

all values for the solution to the inequality are greater than 1
