Answer:

First find the distance between points M and V and the distance between points M and R using the distance formula:

MV = the sq. rt of (-2 - (-5)^2 + (3 - 2)^2

MV = the sq. rt of 9 + 1

MV = the sq. rt of 10

MR = the sq. rt of (-2 - (-5)^2 + (-3 - 2)^2

MR = the sq. rt of 9 + 25

MR = the sq. rt of 34

Now we cut the polygon into a triangle and a rectangle solving each area and adding them together:

Triangle- A = 1/2bh

A = 1/2(6)(3)

A = 9

Rectangle- A=bh

A = 6(5)

A = 30

Now add these areas together- 30 + 9 = 39units^2 and that's your answer

Answer:

The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon. Plug the values of a and p in the formula and get the area.

Answer:

B is false.

Step-by-step explanation:

So based offf the graph, he earns about 7.50 per hour, so A is true, because 7.50(14)= 105.00 or 105, add the dollar. Meaning B has to be false.

Sarah has 284 coins in a piggy bank with a total value of $22.78. Sarah has 173 pennies, 5 more dimes than nickels, the rest are

pickupchik [31]

Let P = number of coins of pennies (1 penny = 1 cent)
Let N = number of coins of nickels (1 nickel = 5 cents)
Let D = number of coins of dimes (1 dime = 10 cents)
Let Q = number of coins of quarters (1 quarter = 25 cents)

a) P + N + D + Q = 284 coins, but P = 173 coins, then:
173 + N + D + Q =284 coins
(1) N + D + Q = 111 coins

b) D = N + 5 OR D - N =5 coins
(2) D - N = 5 coins

c) Let's find the VALUE in CENTS of (1) that is N + D + Q = 111 coins
5N + 10D + 25 Q = 2,278 - 173 (1 PENNY)
(3) 5N + 10D + 25Q = 2105 cents
Now we have 3 equation with 3 variables:

(1) N + D + Q = 111 coins
(2) D - N = 5 coins
(3) 5N + 10D + 25Q = 2105 cents
Solving it gives:
17 coins N ( x 5 = 85 cents)
22 coins D ( x 10 = 220 cents)
72 coins D ( x 25 = 1,800 cents)
and 173 P,
proof:
that makes a total of 85+2201800+172 =2,278 c or $22.78

Find PD if coordinate of P is -7 and the coordinate of D is -1

juin [17]

Answer:

PD = 6 units

Step-by-step explanation:

Co-ordinate of P = - 7

Co-ordinate of D = - 1

So length of PD = | - 7 | - | - 1 |

= 7 - 1

= 6 units

( Length can't be negative at all )
