Answer:

Step-by-step explanation:

The points given are: (1,-4), (7,-7), (13,-10), (19,-13)

They line up to a straight line with slope:

((-4)-(-7))/(1-7) = 3/-6 = -1/2

The equation in point-slope form is

(y-(-4)) = -1/2(x-1)

y+4 = -1/2(x-1)

A is the right answer.

Answer:

Step-by-step explanation:

there is a linear relationship

from the table, x changes by +6, y changes by -3 every time

so that means the slope is constant i.e. its a straight line

slope=(y2-y1)/(x2-x1)=-3/6

= -1/2

take the 1st pt, ( 1, -4 )

(y-(-4)) = slop * (x-1)

y+4 = -1/2*(x-1)

ans is A

∠F and ∠G are supplementary angles. If m∠F is two less than six times the measure of ∠G, find the measures of both angles
Mnenie [13.5K]

Answer:

∠ G = 26°, ∠ F = 154°

Step-by-step explanation:

Express ∠ F in terms of ∠ G, that is

F = 6G - 2

and since the angles are supplementary, then

G + 6G - 2 = 180, that is

7G - 2 = 180 ( add 2 to both sides )

7G = 182 ( divide both sides by 7 )

G = 26

Thus

∠ G = 26° and ∠ F = 6(26) - 2 = 156 - 2 = 154°

A Ferris wheel has a diameter of 56 ft. how far will a rider travel during a 4-minute ride if the wheel rotates once every 20 se
Luba_88 [7]
First calculate the circumference. Usually this is the diameter times pi, but since we are told to estimate pi, the circumference equals 56 * 22/7 or 176 feet.
In 4 minutes, 4 * 60 = 240 seconds pass. In this time, a 20 second period will occur 240/20 = 12 times.
So we know that the rider rotates 12 times and each rotation takes them 176 feet, meaning that they will travel 12 * 176 =  2112 feet

Find the area of each figure. Round to the nearest hundredth where necessary. Only 1 and 5 please!
Alex787 [66]

Answer:

See below

Step-by-step explanation:

To begin, it is volume, not area

1. 8 x 12 x 17 = 1632 in ^3

5. 9 x 9 x 13.5 = 1093.5 in^3

If you want to find SURFACE AREA:

1. 2(8 x 12) + 2(8 x 17) + 2(17 x 12) = 872 in^2

5. 2(9 x 9) + 4(9 x 17) = 774 in^2
