Answer:
$2.45
Step-by-step explanation:
First divide the cost by number of items. you shall get $0.49
Now multiply the cost of 1 candy bar into 5 and you shall get $2.45.
2:05 that would be your anser
A <u>reasonable tip </u>would be $5.00
Rosita paid $27.08 an wants to tip a whole dollar <u>closest to 20%. </u>
The first step is therefore to find out 20% of $27.08.
= 20% x 27.08
= $5.42
The closest whole dollar depends on the first decimal point.
If it is 5 and above, the tip would be $5 as we would round down.
If it is 4 and below, the tip would be $6 as we would round up.
The<u> first decimal </u>is 4 so we would round down to $5.00
The tip would therefore be $5.00

Answer:
Step-by-step explanation:
1) Diagonal bisect the angles of Rhombus
∠CAB = ∠CAD
∠CAB = 71
2) ∠DAB = ∠CAB + ∠CAD
∠DAB = 71 + 71 = 142
In Rhombus, adjacent angles are supplementary
∠DAB + ∠ABC = 180
142 + ∠ABC = 180
∠ABC = 180 - 142
∠ABC = 38
3) In rhombus, opposite angles are congruent
∠ADC = ∠ABC
∠ABC = 38
In rhombus, diagonal bisect angles
∠BDC = (1/2)*∠ADC
∠BDC= 38/2
∠BDC = 19
4) Diagonals bisect each other at 90
∠DEC = 90
5) Diagonals bisect each other
BE = DE
BE + DE = DB
7x -2 +7x -2 =24 {add like terms}
14x - 4 =24
14x = 24+4
14x = 28
x = 28/14
x = 2 m
6) AB = 13m
BE = 7x - 2 = 7*2 -2 = 14 -2 = 12 m
In right angle ΔAEB, {use Pythagorean theorem}
AE² + BE² = AB²
AE² + 12² = 13²
AE² + 144 = 169
AE² = 169 - 144
AE² = 25
AE = √25
AE = 5 m
Diagonals bisect each other
AE = EC
AC = 2*5
AC = 10 m
7)Side = 13 m
Perimeter = 4*side
= 4*13
Perimeter = 52 m
8) d1 = AC = 10 m
d2 = DB = 24 m
Area =
= 10 *12
= 120 m²
