Answer:

63. Perimeter: 60.4 units

Area: 126.14 units²

64. x = 8

m = 62⁰

Step-by-step explanation:

First, let us solve question 63. To find the perimeter and the area of the triangle, we will first find the x and y value.

Formulas we would use to find the answer in Q. 63 :-

Cos = opposite / hypotenuse

Sin = adjacent / hypotenuse

Area = 1/2 × b × h

Perimeter = adding all sides

Let us find the y value using the formula of Cos.

Cos = opposite / hypotenuse

Cos24⁰ = y / 26

26(Cos24⁰) = (y / 26)26

26(Cos24⁰) = y

23.8 = y ---> *since it said to round to the nearest hundredth.*

Now let us find the x value by using the formula of Sin.

Sin = adjacent / hypotenuse

Sin24⁰ = x / 26

26(Sin24⁰) = (x / 26)26

26(Sin24⁰) = x

10.6 = x ---> *since it said to round to the nearest hundredth.*

Now let us find the perimeter and the area.

Area = 1/2 × b × h

Area = 1/2 × 10.6 × 23.8

Area = 126.14 units²

Perimeter = adding all sides.

Perimeter = 26 + 23.8 + 10.6

Perimeter = 60.4 units

On to Q. 64. Formulas we would use to find the answer of Q. 64 is :-

Tan = opposite / adjacent

Sin = opposite / hypotenuse

Let us find m. In order to find m, we will use the Sin formula.

Sin = opposite / hypotenuse

Sinm⁰ = 15 / 17

m⁰ = sin-1(15 / 17)

m⁰ = 62 ---> *since it said to round to the nearest whole number.*

Now let us find x by using the formula of Tan.

Tan = opposite / adjacent

Tan62⁰ = 15 / x

x(Tan62⁰) = (15 / x)x

x(Tan62⁰) = 15

x(Tan62⁰) / Tan62⁰ = 15 / Tan62⁰

x = 15 / Tan62⁰

x = 8 ---> *since it said to round to the nearest whole number.*

Hope this helps, thank you :) !!

Answer:

D) 42.31%

Step-by-step explanation:

If 121 people went to the amusement park out of 286 total students, then the percentage of surveyed students that chose the amusement park would be 121/286=0.4230769231=42.31%, making option D correct.

Step-by-step explanation: Multiply the diameter by pi OR you could divide the diameter by 2 and then use the formula 2(pi)(radius).

Answer:

x=24.27 and x=27.54

Step-by-step explanation:

cos(21)=x/26

x=26*cos(21)=24.27

sin(33)=15/x

x=15/(sin(33))

x=27.54

Step-by-step explanation:

F = ma

= (24.3 kg)(1.2 m/s^2)

Answer:

248

Step-by-step explanation:

Solution for What is 400 percent of 62:

400 percent *62 =

(400:100)*62 =

(400*62):100 =

24800:100 = 248

Now we have: 400 percent of 62 = 248

Question: What is 400 percent of 62?

Percentage solution with steps:

Step 1: Our output value is 62.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$62=100\%.

Step 4: Similarly, x=400\%.

Step 5: This results in a pair of simple equations:

62=100\%(1).

x=400\%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

\frac{62}{x}=\frac{100\%}{400\%}

Step 7: Again, the reciprocal of both sides gives

\frac{x}{62}=\frac{400}{100}

\Rightarrow x=248

Therefore, 400 of 62 is 248

Answer:

248

Step-by-step explanation:

[tex]\frac{y}{400}: \frac{62}{100}[/tex]

y · 100 = 62 · 400

100y = 24800

100y ÷ 100 = 24800 ÷ 100

y = 248

Answer:

y=3/2x-5/2

Step-by-step explanation:

subtract the 3x from both sides and then divide everything by -2.

Answer:

[tex]9^{12}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

[tex](9^3)^{4}[/tex] = [tex]9^{3(4)}[/tex] = [tex]9^{12}[/tex]
