$28 lunch; 15% tip what's the answer

Answers

Answer 1

Answer: To do this you want to first multiply 28 by 0.15. This will give you $4.20. You have to give a $4.20 tip. The total cost would be the lunch and the tip added together. It would give you a final total of $32.20.

you are working as an assistant to a chef. the chef has 8 cups of berries and will use 2/3 cup of berries for each dessert he makes. how many desserts can he make?

Answers

we know that

by proportion

$((2/3))/(1)(cups)/(dessert) =(8)/(x) (cups)/(desserts)\n \n(2)/(3)(cups)/(desserts) =(8)/(x) (cups)/(desserts) \n \n2*x=8*3\n \nx=24/2\n \nx=12\ desserts$

therefore

the answer is

$12\ desserts$

zero because assistants don't know anything and only the chef can cook

jk

ok so how many 2/3's are in 8?

easy way to compar is
make 8 into a fraction over 3
8/1 times 3/3=24/3

how many 2/3 are in 24/3
how many 2's are in 24
12

answer is 12 desserts

X - 3/8 = 3/6

what is x.

Answers

X-3/8=3/6
Add 3/8 to both sides, to leave the variable alone
X= 3/6-3/8
Use common denominators-8 (3/6 is 1/2)
X= 4/8-3/8
X=1/8

Answer:

X is 7/8 or if decimal is need it is 0.875

The area of circular garden is 379.94 feet2. What is the circumference of the garden? (Use 3.14 for .)

Answers

we have to find out the radius of the circle.
area of a circle=πr²
379.94 ft²=(3.14 * r²)
r²=379.94 ft² / 3.14
r²=121 ft²
r=√(121 ft²)
r=11ft

Now, we calculate the circumference of the garden.
circumference =2πr
circumference=2*3.14*11 ft=69.08 ft

Answer: the circumference is 69.08 ft,

The angle of depression of a boat at sea from a 100 foot lighthouse is 20 degrees. Find the distance to the boat.not sure how to solve this..

Answers

Answer:

As per the statement:

The angle of depression of a boat at sea from a 100 foot lighthouse is 20 degrees.

We draw the figure for this problem as shown below:

Height of the lighthouse(BC) = 100 foot

Angle of depression = 20 degrees.

Since, angle of depression is equal to the angles of elevation

i.e, $\angle DCA = \angle CAB = 20^(\circ)$

using tangent ratio:

$\tan \theta = \frac{\text{opposite side}}{\text{adjacent side}}$

Here,

Opposite side = BC = 100 foot

Adjacent side = AB

Angle of elevation: $\theta = 20^(\circ)$

Substitute these to solve for AB:

$\tan 20^(\circ) = \frac{100}{\text{AB}}$

$\text{AB} =(100)/(\tan 20^(\circ))$

$\text{AB} =(100)/(0.36397023426)$

Simplify:

AB = 294.375362123 foot

Therefore, the distance to the boat approximately is 294.4 foot

Final answer:

By using the tangent function with the given height of the lighthouse and the angle of depression, we can solve for the distance to the boat, which is approximately 274.1 feet.

Explanation:

In this scenario, we can use trigonometry to find the distance to the boat. Since we know that the lighthouse is 100 feet high and the angle of depression is 20 degrees, this fits the scenario for a tangent function, where tangent of an angle equals the opposite side divided by the adjacent side.

Setting up our function, we get tan(20) = 100/ distance to the boat. Since we want to find the distance to the boat, we can rearrange the equation to be distance to the boat = 100 / tan(20).

Doing this calculation, we find that the distance to the boat is approximately 274.1 feet.
