Solve the right triangle.

Round your answers to the nearest tenth.

Answer:

A = 48°

b = 13.5

c = 20.2

Step-by-step explanation:

✔️A = 180° - (90° + 42°) (sum of triangle)

A = 48°

✔️To find b and c, apply trigonometric function.

Reference angle = 42°

Opposite = b

Hypotenuse = c

Adjacent = 15

✅Apply TOA to find b:

Tan 42 = Opp/Adj

Tan 42 = b/15

15 × Tan 42 = b

13.5060607 = b

b = 13.5 (nearest tenth)

✅Apply CAH to find c:

Cos 42 = Adj/Hyp

Cos 42 = 15/c

c × Cos 42 = 15

c = 15/Cos 42

c = 20.1844909

c = 20.2 (nearest tenth)

3. Find the missing side lengths. Leave your answers as radicals in simplest form. Show your work to support

your answer.

Answer: b=2(square root of 2) and a=4

Step-by-step explanation:

Since this is a 45-45-90 triangle we know that side b is equal to [tex]b=2\sqrt{2}[/tex].

In a 45-45-90 triangle, the hypotenuse is equal to [tex]x\sqrt{2}[/tex] this means in order to find missing side length a, we have to multiply [tex](2\sqrt{2})(\sqrt{2})[/tex] this will give us 4

so the missing side lengths are, [tex]b=2\sqrt{2}[/tex] and [tex]a=4[/tex]

**Answer: B = 2 (Square root of 2) A = 4**

**Explanation: This is an isosceles triangle so the legs will be the same. To get the hypotenuse I simply just multiplied one leg by the square root of 2 and two square roots of the same number multiply the whole number by whatever number is in the square root (so in this case it's multiplying 2 by 2)**

Junior's brother is 1 1/2

meters tall. Junior is 1 1/5

of his brother's height.

How tall is Junior?

**Answer:**

**Step-by-step explanation:**

1 1/5 of 1 1/2 meters

= (1+1/5) x (1+1/2)

= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2

= 1 + 1/2 + 1/5 + 1/10

= 1 + (1x5+1x2+1)/10

= 1 8/10

= 1 4/5 meters

**Answer:**

1 4/5 meters

**Step-by-step explanation:**

1 1/5 of 1 1/2 meters

= (1+1/5) x (1+1/2)

= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2

= 1 + 1/2 + 1/5 + 1/10

= 1 + (1x5+1x2+1)/10

= 1 8/10

= 1 4/5 meters

if the value of 12.5% equals 4,000, what is the value of 87.5%?

**Answer:**

**12.5%*7=87.5%**

**4000*7=28000**

**28000**

**Answer:**

28,000

**Step-by-step explanation:**

Since 4,000 is 12.5%, you can divide 87.5/12.5 to see how many times 12.5 goes into 87.5, which is 7 times. so then since you need to find the value of how much 87.5% is, then you can multiply 4,000 by 7 since 7 is 87.5 percent, leaving us with 28000

Consider the following statement. ∀a ∈ Z, (a − 1) a is not an integer. (a) Select the correct negation for this statement. For every integer a, a − 1 a is an integer. There is an integer a such that a − 1 a is not an integer. For every integer a, a − 1 a is not an integer. There is an integer a such that a − 1 a is an integer. (b) Is the given statement true or false? If the statement is true, enter TRUE; if the statement is false, enter a value of a that could be used as part of a counterexample that justifies its falseness.

**Answer:**

a) There is an integer a such that [tex]\frac{a-1}{a}[/tex] is an integer

b) False

**Step-by-step explanation:**

Statement : ∀a ∈ Z, (a − 1) a is not an integer

A) The correct negation will be :

**There is an integer a such that **[tex]\frac{a-1}{a}[/tex]** is an integer**

B) The Given statement is FALSE because

when we assume the value of a = 1

( a - 1 ) / a = (1 - 1 ) / 1 = 0 ; which is an integer

**Answer:**

**Step-by-step explanation:**

I rewrote the question so I wouldn't have to keep going back to the picture.

A poll asked 1000 adults who own smartphones where they put their smartphone while sleeping. The following two-way table of relative frequencies shows the data collected on age and smartphone habits. Of the adults polled, 200 were 65 or older.

How many of the adults polled that were 65 or older sleep with their smartphone within reach?

---------------------------------------------------------------------------------

I bet if I called this a two- way table of "percentages, written as decimals", it would make more sense.

Total number of adults 65 and older = 200. The 0.38 of them that sleep with their phone in reach = 38% of them. Multiply 200 x 0.38 = 76

To check the math, 200 x 0.62 = 124, and 124 + 76 = 200.

**Answer:**

**Step-by-step explanation:**

**Remark**

If you put the slices that have been removed back into the figure, and figure out the resulting rectangle and subtract the slices, you get an answer that is easily calculated.

**Note**

The square on the upper right is 6 cm high. That makes the width of the rectangle 9 + 6 = 15. The length is already known as 15. So this square is 15 by 15 = 225

The lower right triangle is a little harder to handle. The total width is 15. The height of the triangle is 6 + 6. The first 6 comes from the square that was removed. The total with is 15. So the height of the lower right triangle is 15 - 12 = 3

Answer

The answer to the square on the upper left that was removed = 6*6 = 36

The answer to the triangle on the lower right is 1/2 * 6 * 3 = 9

The total of the removed figues is 36 + 9 = 45

The area of the figure with both figures removed is 225 - 45 = 180 cm^2

Composite shapes are made up of **two or more shape**s. The required **volume of the composite shape** in exact form is **498π cubic feet**

Composite shapes are made up of **two or more shape**s. According to the given question, the buoy is made up of a cone and sphere.

The** volume** of the buoy = volume of sphere + volume of the cone

Find the volume of the sphere

Vs = 4/3πr³

Vs = 4/3π(6)³**Vs = **288π cubic feet

**Find the volume of the cone**

Vc = 1/3πr²h

Vc = 1/3π(6)²(10)

Vc = 120π cubic feet

Volume of the buoy = 288π + 120π**V = 498π cubic feet**

Therefore the required **volume of the buoy** in exact form is** 498π cubic feet**

**Step-by-step explanation:**

You are considering a project in Bolivia that would generate 3 million dollars in cash flows per year going forever. The cost of the project is 10 million dollars. The discount rate for the project is 15%. You believe that there is some probability of expropriation prior to the 3rd year (after the 2nd cash flow). Which of the following statements is most correct?

a. This is a good project if the probability of expropriation is larger than.33.

b. This is a good project if the probability of expropriation is smaller than.33.

c. This is a good project if the probability of expropriation is smaller than .

d. This is a good project if the probability of expropriation is smaller than .66.

**Answer:**

b. This is a good project if the probability of expropriation is smaller than .33.

**Step-by-step explanation:**

a) Data and Calculations:

Cash inflows per year going forever = $3 million

Cost of project = $10 million

Discount rate for the project = 15%

The present of a perpetuity = Cash inflow/Discount rate

= $3/0.15 million

= $20 million

NPV = $10 million ($20 - $10 million)

b) The probability of expropriation indicates that the government of Bolivia may likely take over the project after the initial investment had been made. This will cause the investor to lose her investments. If the probability of the expropriation taking place is equal to 0.33, the investor may recover the cost of investment without making any profit in three years' time. But if the probability of expropriation happening is less than 0.33, the investor could recover enough to cover the investment cost.

I have a standard deck of playing cards in one pile, and a deck of 10 distinct Pokémon cards in another

pile. If I randomly choose 3 playing cards and 4 Pokémon cards (and I don't care about the order I draw

them), how many different choices could I make?

**Answer:**

You could make 4,641,000 different choices.

**Step-by-step explanation:**

The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.

**Combinations formula:**

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

**How many different choices could I make?**

3 cards from a set of 52(number of cards on a standard deck).

4 Pokemon cards from a set of 10. So

[tex]T = C_{52,3}*C_{10,4} = \frac{52!}{3!49!}*\frac{10!}{4!6!} = 22100*210 = 4641000[/tex]

You could make 4,641,000 different choices.
