5. The distance from the shovel to the treasure chest is

Tresset [83]

Answer: 110 yards

Step-by-step explanation:

From the question, the distance from the shovel to the treasure chest is

60 yards while the distance from the treasure chest to the boat is 50 yards. We are to calculate the distance from the boat from the shovel.

The distance from the boat from the shovel will be the addition of the distance from the shovel to the treasure chest which is 60 yards with the distance from the treasure chest to the boat is 50 yards.

= 60 yards + 50 yards

= 110 yards

Quadrilateral ABCD is a parallelogram. Given this, fill in the coordinates below.

Lubov Fominskaja [6]

Answer:

The coordinates of D are (8,3)

Step-by-step explanation:

We have quadrilateral ABCD being a parallelogram with coordinates A(3,2), B(5,4), C(10,5), and D(a,b).

We want to find the coordinates of D.

Since ABCD is a parallelogram, the diagonals AC and BD bisects each other.

The midpoint of AC is (13/2,7/2).

This is also the midpoint of BD.

By the midpoint rule:

$( \frac{5 + a}{2} , \frac{4 + b}{2} ) = ( \frac{13}{2} , \frac{7}{2} )$

This implies that:

$5 + a = 13 \\ a = 13 - 5 \\ a = 8$

Similarly,

$4 + b = 7 \\ b = 7 - 4 \\ b = 3$

The coordinates of D are (8,3)

On a recent trip to the convenience store, you picked up 4 gallons of milk, 5 bottles of water, and 8 snack-size bags of chi

Otrada [13]

Answer:

One gallon of milk costs $3.64

One bottle of water costs $2.54

One bag of chips costs $0.79

Step-by-step explanation:

m represent gallons of milk

w represents bottles of water

c represents snack-size bags of chips

t = total bill

t = m + w + c ... eq 1

t = $33.60

but

w = 2c

m = 1.90 + w

m = 1.9 + 2c

Slot in the values in eq 1

33.60 = (1.9 + 2c ) + 2c + c

33.60 = 1.9 + 5c

33.60 - 1.9 = 5c

31.7 = 5c

c = $6.34

Slot in the value of c in w and m

w = 2c

w = 2(6.34)

w = $12.68

m = 1.9 + 2c

m = 1.9 + 2(6.34)

m = $14.58

4 gallons of milk cost $14.58

Therefore, one gallon if milk costs = 14.58/4 = $3.64

5 bottles of water cost $12.68

Therefore, one bottle of water costs = 12.68/5 = $2.54

8 bags of chips = $6.34

Therefore, one bag of chips cost = 6.34/8 = $0.79
