Find The Measure Of Each Missing AngleAngle 21 =Angle 22 =Angle 23 = What Is The Sum Of Angles 21,22

Answers

Answer 1

Answer:

Step-by-step explanation:

Angle 21  is calculated like this:

180 - 70 - 50 = 60 because a line is 180 degrees.

Angle 22 = 50 degrees because it is opposite to the upper angle of 50 degrees.

Angle 23 = 70 degrees because it is also opposite to the upper angle of 70 degrees.

The sum of the angles would be

60 + 50 + 70 = 180 degrees

Points (-2, 4) and (-1, 1) lie on the same line. Which of the following equations represents the line

Answers

Answer:

y = -3x - 2

Step-by-step explanation:

Given the coordinates  (-2, 4) and (-1, 1), we are to find the equation of a line passing through the points.

The standard form of the equation is expressed as;

y = mx+c

m is the slope

m = y2-y1/x2-x1

m = 1-4/-1+2

m = -3/1

m = -3

get the y-intercept c;

Substitute m = -3 and any point say (-1,1) into the equation y = mx+c

1 = -3(-1) + c

1 = 3 + c

c = 1-3

c = -2

Get the required equation;

y = mx+c

y = -3x + (-2)

y = -3x - 2

Raisins (x) that sell for $1.60 per pound are mixed with chocolate chips (y) that sell for $2.45 per pound to make 17 pounds of a mixture. The mixture sells for $2.00 per pound. Which system of linear equations can be used to find the amount of each ingredient in the mixture?
A) xy = 17
1.60x + 2.45y = 34
B) x + y = 17
1.60x + 2.45y = 34
C) x + y = 17
1.60x + 2.45y = 17
D) x + y = 17
1.60x − 2.45y = 34

Answers

Answer: B) x + y = 17

1.60x + 2.45y = 34

Step-by-step explanation:

Cost of x = $1.60 per pound

Cost of y = $2.45 per pound

Total pounds of x and y = 17

Cost per pound of mixture = $2

Total number of pounds of the mixture :

x + y = 17

Since the cost per pound of the mixture = 2

Hence ;

(Cost of x * number of pounds of x) + (Cost of y * number of pounds of y)

(1.60 * x) + (2.45 * y) = (cost per pound of mixture * total number of pounds of the mixture)

1.60x + 2.45y = 2 * 17

1.60x + 2.45y = 34

If the scale factor of Figure A to Figure B is 7:2, find the perimeter of Figure A.

Answers

Answer:

122.5 units

Step-by-step explanation:

The proportion would be between the perimeters and the given ratio:

7/2 = p/p

Where P is the perimeter of the bigger figure and p is the perimeter of the smaller figure.

Remember that the perimeter is the sum of all sides, using all given values and solving for P, we have

7/2=P/9+5+9+12

7/2=P/35

7(35)/2=P

P=245/2=122.5

Therefore, the perimeter of Figure A is 122.5 units.

Gavin works as a salesperson at an electronics store and sells phones and
phone accessories. Gavin earns a $12 commission for every phone he sells
and a $3.50 commission for every accessory he sells. On a given day, Gavin
made a total of $135 in commission and sold 12 more accessories than
phones. Determine the number of phones sold and the number of accessories
sold.

Answers

Answer: Hence, there are 6 phones and 18 accessories sold.

Since we have given that

Let number of phones sold be 'x'

Let number of accessories sold be 'y'.

Commission for every phone = $12

Commission for every accessory = $3.50

Total commission = $135

And Difference between accessories and phones sold = 12

According to question, we get that

Using both the equations, we get that

x=6 and y = 18

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where, W, is her wages and, V, is the number of overtime hours worked.

Answers

Answer:

W = 450 + 16.83V

Step-by-step explanation:

For 40 hours Carissa

earning = $450

earning for 1 hour of over time = $16.83

multiplying both side by V

earning for v hour of over time = $16.83*V = $16.83V

weekly wage(W) = earning for 40 hours + earning for V hour of over time

W = 450 + 16.83V

Thus equation will be as given below for weekly earning
