Someone know this question??
Bogdan [553]
Hhhhmmmmm...

13.50 for food
2.40 for drink

Since there is a voucher for 1/3 of food,

13.50 multiplied by 1/3 is 4.5 which is the discount

13.50-4.5=9

9 is the final cost for the food.

Add 9 to 2.40 for the drink which results in a total of 11.40

To find the amount charged for service you multiply 11.40 by .15

11.40 × .15 = 1.71

You add 1.71 to 11.40

The total is 13.11

A tree struck by lightning in a storm breaks and falls over to form a triangle with the ground. The tip of the tree makes a 36°
liraira [26]

Answer: approximately 49 feets

Step-by-step explanation:

The diagram of the tree is shown in the attached photo. The tree fell with its tip forming an angle of 36 degrees with the ground. It forms a right angle triangle,ABC. Angle C is gotten by subtracting the sum of angle A and angle B from 180(sum of angles in a triangle is 180 degrees).

To determine the height of the tree, we will apply trigonometric ratio

Tan # = opposite/ adjacent

Where # = 36 degrees

Opposite = x feets

Adjacent = 25 feets

Tan 36 = x/25

x = 25tan36

x = 25 × 0.7265

x = 18.1625

Height of the tree from the ground to the point where it broke = x = 18.1625 meters.

The entire height of the tree would be the the length of the fallen side of the tree, y + 18.1625m

To get y, we will use Pythagoras theorem

y^2 = 25^2 + 18.1625^2

y^2 = 625 + 329.88

y^2 = 954.88

y = √954.88 = 30.9 meters

Height of the tree before falling was

18.1625+30.9 = 49.0625

The height of the tree was approximately 49 feets

alukav5142 [94]

Answer: x + 100

Step-by-step explanation:

From the question, we are told that Bobbie has 100 more followers than Debora and x is used to represent the number of followers that Debora has.

The expression that shows the number of followers Bobbie has will be the number of followers that Debora has plus 100. This will be :

= x + 100
