Answer:

x = 70

Step-by-step explanation:

Ok first let's find the angle where there is an exterior angle:

180-120=60

Then add this and the other inside known angle and subtract that from 180 to get your answer:

60+50=110

180-110=70

Answer:

70

Step-by-step explanation:

Sum of two interior angles equals to the exterior angle.

Answer:

corresponding angles

Step-by-step explanation:

x and y are in the same position in relation to the lines.  They are to the right of the transversal and above the horizontal lines.

This means they are corresponding angles

If its just 15 then its 1

Step-by-step explanation:

Because 15 divided by 1 is 15 which is the fraction.

Answer:

Below,...!

Step-by-step explanation:

15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:

[tex]\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}[/tex]

15/1 is your fraction so 15/1 divided into 15 equals 1

[tex]\frac{15}{1} / 15 = 1/1 = 1[/tex]

Answer:

t = 4.875 s

h(4.875) = 686.25 ft

t ≈ 11.424 s

Step-by-step explanation:

These questions are more easily answered if the equation is written in vertex form. Subtracting the constant and dividing out -16, we get ...

h(t) -306 = -16(t^2 -9.75t)

Adding the square of half the t-coefficient inside parentheses gives ...

 h(t) -306 -380.25 = -16(t^2 -9.75t +23.765625)  

 h(t) = -16(t -4.875)^2 + 686.25

This tells us the maximum height is 686.25 ft at time t = 4.875 seconds.

__

When the rock hits the ground, h(t) = 0, so ...

0 = -16(t -4.875)^2 + 686.25

686.25/16 = (t -4.875)^2 . . . . . subtract 686.25, divide by -16

√42.890625 +4.875 = t ≈ 11.424 . . . . take the square root, add 4.875

The rock hits the ground after about 11.424 seconds.

The sum of 21 terms is -1080.

given:

- 18, - 15,-12.....

First term, a= -18

common difference, d= -15 + 18= -3

So, [tex]S_{21[/tex] = 21/2 [ 2(-18)+ (21- 1) (-3)]

[tex]S_{21[/tex] = 21/2 [ -36 + (20) (-3)]

[tex]S_{21[/tex] = 21/2 [ -36 - 60]

[tex]S_{21[/tex] = 21/2 (-96)

[tex]S_{21[/tex] = 21 x (-48)

[tex]S_{21[/tex] = -1008

Hence, the sum of 21 terms is -1080.

The sign's area is 80 square inches.

A rectangle is a quadrilateral. This means that a rectangle has four sides.

The area of a rectangle = length x width

Perimeter of a rectangle = 2 x ( length + width)

Let the width of the sign be represented with w

The length of the sign is 5x

Substitute these dimensions into the formula for the perimeter of a rectangle.

(x + 5x) = 24

6x = 24

x = 24/6

x = 4 inches

The length is 5 x 4 = 20 inches

Area of the sign = 20 x 4 = 80 inches²

Answer:

3.00x10^8

Step-by-step explanation:

So you want to make sure the number before the x10^ is beween 10 and 0 not including 10 and 0. So 1.00-9.99.

Move the demcil place up in 300,000,000 till your first number is between 1 and 9.99.

Then count how many places you moved it up, in this case 8

Add the amount of times you moved up to the x10^(in this space).

you answer is now 3.00 plus the x10^8

3.00x10^8

first, let's break the equation down.

y=7x-4

-4 represents your staring coordinate, or your y-intercept. This is because -4 does not have an x after so you know it is equal to your y value. So you start at (0,-4)

Now all you need to do is the y=7x part.

The 7x represents your slope.

Slope is equal to rise/run or y/x.

So for each coordinate, you go up 7 and to the right 1.

(0,-4)

Answer:

0.2

Step-by-step explanation:

If it takes 10 seconds to move 1 centimetres, and you want to know about 2 seconds, you can divide by 5 on both sides.

1/5 = 0.20

It takes 2 seconds to move 0.2 centimetres (aka 20 milimetres).

The snail will travel 0.2 centimetre in 2 seconds.

it takes the snail 10 seconds to move 1 centimetre. The means in every 10 seconds the snail moves 1 centimetre.

The distance the snail can cover in 2 seconds can be computed below:

10 seconds = 1 cm

2 seconds = ? cm

cross multiply

distance it takes the snail to travel in 2 seconds = 2 / 10

distance it takes the snail to travel in 2 seconds = 1 / 5

distance it takes the snail to travel in 2 seconds = 0.2 cm

Therefore, the snail will travel  0.2 cm in 2 seconds .
