What is the length of the line segment with endpoints (−3,8)(−3,8) and (7, 8)(7, 8) ????????

What are the mensure of 1 angle and 2 angle? Show ur work or explain

STatiana [176]

Answer:

angle 1 = 105º

angle 2 = 75º

Step-by-step explanation:

angle 2 = 75º

corresponding angle to the 75º angle

angle 1 = 105º

it's supplementary to angle 2

180 - 75 = 105

A cafe sells puffs. 5/9 are beef and 1/3 are chicken. The remaining 18 are tuna. Calculate 1. What fraction of the puffs are tun

Ksivusya [100]

Let n be the total number of puffs. Now we can write:
$n=\frac{5}{9}n+\frac{1}{3}n+18$
Adding the fractional value of n, we get:
$n=\frac{5+3}{9}n+18$
Simplifying and rearranging gives us:
$n-\frac{8}{9}n=18$
Therefore we can simplify to get:
$\frac{1}{9}n=18$
and finally
$n=18\times9=?$
The fraction of the puff that are tuna is found from:
$\frac{18}{18\times9}=\frac{1}{9}$

Jake set up a study schedule. The plan called for him to study 1/4 hour, 5/8 hour and 1 hour on Monday Tuesday and Wednesday in

Ludmilka [50]

Each day his study time is increasing. Find a common denominator, in this case 8

1/4 = 2/8
5/8 = 5/8
1 = 8/8

So he went from

2/8 to 5/8 to 8/8 which is an increase of 3/8 each day. If this pattern continues Thursday would be 11/8 and Friday 14/8.

14/8 = 1 6/8 = 1 3/4 hours

(an hour and 45 minutes)

A tourist purchases a car in england and ships it home to the united states. the car sticker advertised that the car's fuel cons

Valentin [98]

<u>Solution-</u>

Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)

1 UK gallon = 4.5459631 lit

1 US gallon = 3.7853060 lit

$\therefore \frac{1 \ UK \ gallon}{1 \ US \ gallon} = \frac{4.5459631}{3.7853060} = 1.2009499$

$\Rightarrow 1 \ UK \ gallon = 1.2009499 \ US \ gallon$

As the fuel consumption rate = 40 miles per gallon

⇒ You need 1 UK gallon of fuel to go 40 miles

⇒ You need 1.2009499 US gallon of fuel to go 40 miles

Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel

⇒ To go 1 mile you will need $\frac{1.2009499}{40} = 0.0300237$

⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel

∴ 22.1574906 gallon of fuel is actually required.

∴ But, what she thinks will require is $\frac{738}{40} = 18.45 gallons$ (As she calculated using UK gallons)

A linear regression is done on data the line of best fit is y= 1.25x-6.25. What is the residual for the point (1,1)?

Damm [24]

Answer:

6

Step-by-step explanation:

Find the predicted y value when x=1:

$\hat{y}=1.25x-6.25\\\hat{y}=1.25(1)-6.25\\\hat{y}=1.25-6.25\\\hat{y}=-5$

Find the residual:

$\text{Residual}=\text{Actual Value}-\text{Predicted Value}\\\text{Residual}=y-\hat{y}\\\text{Residual}=1-(-5)\\\text{Residual}=1+5\\\text{Residual}=6$

Because our residual is positive, this is an indicator that our predicted y value is too low.
