Answer:

-8/9

Step-by-step explanation:

my work is in the picture above. lmk if you'd like me to explain more

The slope of line [n] would be -8/9.

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

We have line [m] passes through points (10, 10) and (2, 1).

We can write the equation of line [m] as follows.

slope of line [m] = a = (1 - 10)/(2 - 10) = -9/-8 = 9/8

a = 9/8

slope of line [n] -

m[n] x a = - 1

m[n] = -1/a

m[n] = -8/9

Therefore, the slope of line [n] would be -8/9.

Answer:

7π mm²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × [tex]\frac{280}{360}[/tex] ( r is the radius )

   = π × 3² × [tex]\frac{28}{36}[/tex]

    = 9π × [tex]\frac{7}{9}[/tex] ( cancel the 9's )

    = π × 7

    = 7π mm²

Answer:

Answer:

$64.00

Step-by-step explanation:

Company A:

C = 3.25x

3.25 x 80 = 260

Company B:

C = 2.45x

2.45 x 80 = 196

How much more?

260 - 196 = 64

Difference in Total price for 80 unit is $84

Per spirit cost in company A = 3.5 per spirit

Cost equation for company B = C = 2.45x

Difference in Total price for 80 unit

Difference in Total price for 80 unit = 80[3.5 - 2.45]

Difference in Total price for 80 unit = 80[1.05]

Difference in Total price for 80 unit = $84

Answer:

Step-by-step explanation:

Step one:

given data

For Ennis

distance covered= 3 miles

time taken = 20 minutes

Hence Ennis speed is

velocity= distance/time

velocity= 3/20

velocity=0.15miles per minutes

Therefore in 1 hour that is 60 minutes the distance she will cover is

distance= velocity * time

Distance= 0.15*60

Distance= 9 miles

Step two:

For Cindy

distance covered= 6 miles

time taken = 30 minutes

Hence Cindy speed is

velocity= distance/time

velocity= 6/30

velocity=0.2miles per minutes

Therefore in 1 hour that is 60 minutes the distance she will cover is

distance= velocity * time

Distance= 0.2*60

Distance= 12 miles

Answer:

x = 16

DISREGARD 16.5 MY BAD the answer is 16

Step-by-step explanation:

140 = 8x+12

Subtract 12 on both sides

128 = 8x

Divide by 8

16 = x

x = 16

Answer:

x = 16

Step-by-step explanation:

(8x + 12)° = 140°

8x + 12 = 140

8x = 128

x = 128 ÷ 8

x = 16

Answer:

Correct Answer is B

39 m

Step-by-step explanation:

Perimeter is the sum of all sides, and if the length is 6m more than the width, then is 39

39 + 39 = 78

144 - 78 = 66

66/2 = 33

39m is 6m more than 33m.

The sum of all sides 39 + 39 + 33 + 33 = 144

Answer:

x = 44°

Step-by-step explanation:

The sum of the exterior angles of any polygon my be 360°, so just add all the angles up, and subtract this from 360°.

Given a pentagon with exterior angles: 102°, 47°, 34°, and 133° with the missing angle x°.

To find the missing angle, first write an equation representing the given rule:

102° + 47° + 34° + 133° + x° = 360°

(316°) + x° = 360°

316° + x° - 316° = 360° - 316°

x° = 44°.

This way, because the rule must be true, the missing angle with this value will satisfy this:

102° + 47° + 34° + 133° + 44° = 360°

For this topic, here are some general angle rules for polygons:

Answer:

6°F

Step-by-step explanation:

Given that:

Temperature at 11pm = 48°F

Temperature at 7am = 6° cooler

Temperature at 11am = 48°F

Number of degrees temperature changed from 7am to 11 am

Exact temperature at 7am = (temperature at 11 pm - 6°)

= 48°F - 6°F

= 42°F

Temperature change from 7am to 11am

Temperature at 11 am - temperature at 7am

48°F - 42°F

= 6°F

Answer:

[tex]y-6=-6(x-1)[/tex]

Step-by-step explanation:

A point-slope equation requires two values in order to write it: one coordinate and the slope.

First, find the slope between the two given points. To find the slope, you would subtract the first Y from the second Y and the first X from the second X. Y goes on top of the fraction bar, making the equation look like this:

[tex]\frac{6-(-6)}{1-3}[/tex]

Then, simplify the slope equation:

[tex]\frac{6-(-6)}{1-3} = \frac{6+6}{1-3} = \frac{12}{-2} = -6[/tex]

The slope is -6.

Finally, choose one of the coordinates. For this, I'll pick (1, 6).

The point-slope equation is [tex]y-y_{1} =m(x-x_{1})[/tex]

So, simply fill in the [tex]m[/tex], [tex]y_{1}[/tex] , and [tex]x_{1}[/tex] spots with the value we have found.

[tex]m[/tex] is the slope, so replace it with -6.

[tex]y_{1}[/tex] = 6

[tex]x_{1}[/tex] = 1

Final answer:

[tex]y-6=-6(x-1)[/tex]

Answer:

Blake will jog 12 blocks

Step-by-step explanation:

Allison : Blake = 3 : 2

If they keep jogging at the same rate, how many blocks will Blake jog if Allison jogs 18 blocks?

Allison : Blake = 18 : x

Equate the ratios

3 : 2 = 18 : x

3/2 = 18/x

Cross multiply

3 * x = 2 * 18

3x = 36

Divide both sides by 3

x = 36 / 3

= 12

x = 12

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

The function f gives the temperature in degrees Celsius t hours after midnight.

Therefore, for the temperature at 12:00 AM (exactly midnight), we will have f(0).

For 1:00 AM, 1 hour after midnight, we will have f(1).

And for 12:00 PM (noon), we will have f(12).

We want to find the equation that represents the temperature at 1:30 PM.

1:30 PM is 13.5 hours after midnight or 1.5 hours after noon.

Therefore, the correct statement would be:

f(13.5)=20.

Hence, our answer is D.
