Answer:

65

Step-by-step explanation:

It’s 65 because 65+35=100 then u add 80 to get 180

The measure of the third angle in the triangle is 65°. The correct option is B.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that Triangle P Q R. Angle Q is 80 degrees and angle P is 35 degrees. Triangle W X Y. Angle W is 35 degrees and angle X is 80 degrees.

The third angle will be calculated as:-

Angle = 180 - 80 - 35

Angle = 65

Therefore, the measure of the third angle in the triangle is 65°. The correct option is B.

Answer:

y = 3x + 1

Step-by-step explanation:

m = ( 1 - 4 ) / ( 0 - 1 ) = 3

( 0 , 1 )

y - 1 = 3(x - 0)

y - 1 = 3x

y = 3x + 1

Answer:

y=3x+1

Step-by-step explanation:

Slope is (y2-y1)/(x2-x1)

therefore slope =

(1-4)/(0-1)

-3/-1

m=3

therefore the equation is

y-y1=m(x-x1)

y-4=3(x-1)

y-4=3x-3

Answer:

37.5%

Step-by-step explanation:

the savings on the sweater is 140-87.50, or 52.50

you could create a proportion based on the statement:

52.50 is what percent of 140?

is/of = 'x'/100

52.5/140 = x/100

cross-multiply to get:

140x = 5250

x = 5250/140

x = 37.5

Answer: 15 gallons

Step-by-step explanation:

Here you are going to want to set up a proportion. 918 miles per 27 gallons = 510 miles per x gallons

918/27 = 510/x

Cross multiply and you get 918x = 13770

and you get x = 15

Or you could do 918 miles / 27 gallons = 34 miles / gallon

and divide the 510 miles of distance by how many miles per gallon, so

510 / 34

15

Answer:

Let's find the unit rate first, I like to order my units:

_________ = ______ = ______________, so 3 patients per hour is the

-unit rate.

Now let's order them to equal x(unknown patients)/9(hours)

___________  =   __________ = 27 patients per 9 hours. So your answer

is 27 patients.

Answer:

27 patients

Step-by-step explanation:

18patients = 6 hours

18/6 = 3

each hour for 6 hours she attends to 3 patient

6 hours + 3 hours make up 9 hours

since for each hour she attended to three patients we would say

1 hr = 3 patients

1 hr = 3 patients

1 hr = 3 patients

Total: 3 hrs = 9 patients

18 patients + 9 patients = 27 patients

so for 9 hrs Katherine will visit 27 patients.

Step-by-step explanation:

The formula for midpoint is: M = [tex]\frac{(x_{1}+x_{2} )}{2} , \frac{(y_{1} + y_{2}) }{2}[/tex]

Measure the distance between the two end points, and divide the result by 2. This distance from either end is the midpoint of that line. Alternatively, add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.

  x² +2x -3 = 0

Step-by-step explanation:

Given the zeros of a quadratic function the factored form is easily found. There is a factor (x -p) for each zero x = p. Here, the factored form of the function is ...

  0 = (x -(-3))(x -1) = (x +3)(x -1)

In standard form, this is ...

  x(x -1) +3(x -1) = 0

  x² +2x -3 = 0 . . . . . . the terms have no common factors
