Answer:

\frac{y2 - y1}{x2 - x1}  \\  \\ 1) \frac{ - 13 - 20}{3 - ( - 16) } \\  \frac{ - 33}{3 + 16}  \\  =  \frac{ - 33}{19}

2) \frac{31 - 23}{27 - 18}  \\  =  \frac{8}{9}

3)\frac{ - 25 - 18}{20 - 12}  \\  =  \frac{ - 43}{8}

4) \frac{21 - 18}{25 - 26}  \\ \frac{3}{ - 1}   \\  =  - 3

5)\frac{11 - 16}{15 - 14}  \\  \frac{ - 5}{1}  \\  =- 5

Can someone plz solve for A&amp;B? Plz and if you do thank you so much :)
Anna71 [15]

Answer:

Part a-

area= 35

perimeter= 31

part b-

area= 25

perimeter= 18

Step-by-step explanation:

to find the area of a triangle you multiply 1/2Bh

so for part A:

A= \frac{1}{2} (10)(7) (honestly, you can just input the whole equation into the calculator)

A=(5)(7)

A= 35

and for part B:

A= \frac{1}{2}(8.34)(6)

A= (4.17)(6)

A=25.02 (or just 25)

THEN, to find the perimeter you add up all of the sides

so for part A:

P= 14 + 10 + 7 = 31

and for part B:

P= 4 \frac{1}{3} + 8 \frac{1}{3}  + 5 \frac{1}{3} = 17 \frac{3}{3} or 18

I hope this helps :)

A bus can carry a maximum of 60 passengers. Each row accommodates the same number of passengers. If two rows are added then each
VashaNatasha [74]

Answer:

10 rows with 6 passengers per row

Step-by-step explanation:

Let x be the number of rows and y the number of passengers per row.

Then we can interpret the story as the following two equations:

xy=60

(x+2)(y-1)=60

Solving these two equations:

y=60/x

(x+2)(60/x-1)=60     (substitute y)

60 - x + 120/x - 2 = 60 (multiply by -x)

x² + 2x - 120 = 0     (factor)

(x-10)(x+12) = 0

x = 10

y = 60/10 = 6

and indeed 10 * 6 = 60 and also 12 * 5 = 60

May someone please help me in this question?
IRINA_888 [86]
To determine the answer for this, you need to divide the amount earned by hours worked to get how much she is paid per hour.
22.50/3 = 7.50
60.00/8 = 7.50
112.50/15 = 7.50
Your answer is A.) A = 7.50h, meaning $7.50 per hour.
I hope this helps!
