The radius of a circle is 3.1 find the circumference to the nearest tenth

Answer:

y=1 1/2 (fraction)

or

y=1.5 (decimal)

Step-by-step explanation:

We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.

3/4= 1/2y

multiply each side by 2

To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators

2•3=6 & 4 • 1 =4

6/4

simplify

y=1 1/2

(If you need it in decimal form it would be y=1.5)

Answer: Airplane A by a scale factor of 1.02

Step-by-step explanation:

Airplane A: 1273/4=318.25

Airplane B: Rate is the slope of equation, 621/2=310.5

So,

318.25/310.5=1.0249

Airplane 'a' is faster than airplane 'b' by a factor of  1.03 times.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An airplane 'a' traveled 1273 miles in four hours.

∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.

For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours

∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.

So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

Answer:

C. From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

Answer:

C

Step-by-step explanation:

y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.

Answer:

The answer is 3%

Step-by-step explanation:

1.) $160 divided by $164.80 = 1.03

2.) 1.03 x 100 = 103

3.) 103 - 100 = 3

4.) 164.80 - 160 = 4.80

5.) 4.80 divided by 160 = 0.03

6.) 0.03 x 100 = 3%

Answer:

44

Step-by-step explanation:

I'm assuming you're meant to multiply so I did 3(14)+2 and it gave me 44 :)

Answer:

so it should be 44

Step-by-step explanation:

So the sub for b is 14 so substitute the b to 14

Then 3(14) they are multiplying so multiply them should equal 42

Then add the 2 the answer should be 44

Answer:

35/-7

Step-by-step explanation:

you want to do the second y- the first y over the second X- the first x to GRT the slope

Answer:

35/-7

Step-by-step explanation:

To calculate slope, you use the slope formula: y2 - y1

                                                                              x2 - x1

So 36.5 - 1.5      

    -5 - 2            

And that equals 35/-7

y = 3x-5

Step-by-step explanation:

this is becuase the y-intercept of these points falls to around -5 (a point actually crosses the y axis at -5)

the gradient of these points is too steep to be x and the slope is not negative - therefore the slope must match closest to 3x.
