the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of the shadow is 49 feet. at that time of day, the sun's rays make an angle of 38° with the ground. How tall is the flagpole?​

Answers

Answer:

30.17feet high

Step-by-step explanation:

Given the following

the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)

angle of elevation = 38°

Required

Height of the flagpole (opposite)

Using the SOH CAH TOA identity

Sin theta = opposite/hypotenuse

Sin 38 = H/49

H = 49sin38

H = 49(0.6157)

H = 30.17feet

Hence the flagpole is 30.17feet high

find the area of the triangle below!!!

Answers

Answer:

[tex]104in^{2}[/tex]

Step-by-step explanation:

area of a triangle is just (b)(h)/2

(13)(16)/2

208/2

104 in squared

Answer:

104ft²

Step-by-step explanation:

formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has a base length of 16 ft and a height of 13 ft

Using this information we plug in the values into the formula

[tex]A=\frac{16*13}{2}\\16*13=208\\\frac{208}{2} =104\\A=104ft^2[/tex]

Hence, the answer is 104ft²

Which number is rational?
/2
10
O
16

Answers

Answer:

16

Step-by-step explanation:

Square root of 2 is irrational. This has been proven by the Pythagoreans (there is a simple proof of that).

pi is also known to be irrational although the proof is a bit more demanding.

Square root of 10 can be written as a product of square root of 5 and square root of 2, which themselves are irrational. Any product involving an irrational number is irrational

Square root of 16 = 4. 4 can be written as a fraction 4/1, or 8/2, 16/4, etc. and therefore is rational by definition.

need help, I'm stuck on this​

Answers

Answer:

The answer is 729/64.

Step-by-step explanation:

I would first simplify the equation.

In the denominator, you can get rid of b^0 because that just equals 1.

For the a's in the numerator and denominator, you have to flip them so the exponents can be positive.

Equation:  [tex](\frac{3ab^2}{2a^3})^2[/tex]

Now, you can subtract a and a^3.  This would be 1/a^2.

Equation: [tex](\frac{3b^2}{2a^2})^2[/tex]

Now, you can square the whole equation.

Equation: [tex]\frac{9b^4}{4a^4}[/tex]

This is the simplified equation.  Now you can plug in -2 and -3.

Equation: [tex]\frac{9(-3)^4}{4(-2)^4}[/tex]

Equation: [tex]\frac{9(81)}{4(16)}[/tex]

Equation: 729/64

235.5 = 3.14 x d^2/4 x 3
235.5 = 9.42 x d^2/4
235.5/9.42 = d^2/4

Step-by-step explanation:

Complete question

Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.

Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.

Write an equation to represent the number of stamps in Tom’s collection based on the  number of weeks he has been collecting stamps.

Solution

Let "X" be the number of weeks for which Tom collected the stamps

The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]

It is given that he collects 8 stamps per week

So the total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

The graph shows the daily sales goal of
a coffee shop. If the employees sell
20 cups of coffee, how many cups of tea
must they sell to meet their goal?

Answers

Answer:

25 cups of tea

Step-by-step explanation:

On the x-axis, we have the number of cups of coffee plotted against the number of cups of tea which are plotted on the y-axis to represent the daily sales goals.

From the graph, when 20 cups of coffee are sold (x = 20), a corresponding sales of 25 cups of tea (y = 25) would be sold as well to meet the sales goal.

Therefore, when employees sell 20 cups of coffee, 25 cups of tea must be sold to meet their goal.
