15 points, solve a right triangle. Please simplify your answers as it says in the picture.

Answer:

Step-by-step explanation:

(5a + 18) + (48 - a) + (8a - 30) = 180 (Angles on a straight line)

5a + 18 + 48 - a + 8a - 30 = 180

12a + 36 = 180

12a = 180 - 36

a = 144/12

a = 12

therefore, the first angle is, 78 degree, second angle is 36 degree and third angle is 66 degree.

Therefore, the size of the smallest angle is 36 degree

B. 80 students

Step-by-step explanation:

[tex]\frac{56}{y} :\frac{70}{100}[/tex]

y · 70 = 56 · 100

70y = 5600

70y ÷ 70 = 5600 ÷ 70

y = 80

Answer:

The company must replace 0.0042 = 0.42% of packages.

Step-by-step explanation:

For each screw, there are only two possible outcomes. Either it is defective, or it is not. The probability of an screw being defective is independent of any other screw. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [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]

And p is the probability of X happening.

It is known that screws produced by a certain company will be defective with probability 0.01.

This means that [tex]p = 0.01[/tex]

The company sells the screws in packages of 10

This means that [tex]n = 10[/tex]

That is, the package would have to be replaced if greater or equal to 2 screws are defective. What proportion of packages sold must the company replace?

This is:

[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]

In which:

[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{10,0}.(0.01)^{0}.(0.99)^{10} = 0.9044[/tex]

[tex]P(X = 1) = C_{10,1}.(0.01)^{1}.(0.99)^{9} = 0.0914[/tex]

[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.9044 + 0.0414 = 0.9958[/tex]

[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.9958 = 0.0042[/tex]

The company must replace 0.0042 = 0.42% of packages.

Answer:

D

Step-by-step explanation:

Do I need to explain?

Answer:

D(8)

Step-by-step explanation:

So remember, 2 opposite sides of a triangle are equivelent.

We know that one of these sides are 3.

So the other side must be 3 as well.

This is 2 of the 4 sides of a rectangle.

If each side is 3, and there are two sides, this means that they add up to 6.

Subtract this from your total permiter:

22-6

=

16

Now remember, there are 2 sides left.

To find the answer, divide the 16(permiter left) by the 2(sides left):

16/2

=

8

This is your answer!

Hope this helps! :)

let h= 4, k=-2 and r= 7 then

(x-h)^2 + (y-k)^2 = r^2

(x-4)^2 + (y+2)^2 = 7^2

x^2 -8x +16 + y^2 +4y +4 = 49

x^2 +y^2 -8x +4y +16 +4-49 = 0

x^2 + y^2 -8x +4y -29 = 0 is the required eq

Answer:

Difference between both pay = £5

Step-by-step explanation:

Given:

Basic pay of Ryan = £60 per day

Basic pay of carl = £60 per day

Ryan get bonus = 25% of basic pay

Carl get = £20 as tip

Find:

Difference between both pay

Computation:

Total of Ryan pay = 60 + 25%(60)

Total of Ryan pay = 60 + 15

Total of Ryan pay = £75

Total of Carl pay = 60 + 20

Total of Ryan pay = £80

Difference between both pay = 80 - 75

Difference between both pay = £5

Answer:

4th Option, [tex]\frac{12}{5}[/tex]

Hope this helps!

Answer:

See answers below

Step-by-step explanation:

Using the sin rule

a/sinA = b/sinB = c/sinC

a) x/sin110 = 16/sin27

xsin27 = 16sin110

xsin27  = 15.035

x = 15.035/sin27

x = 33.1

2) Using the cosine rule;

x² = 30²+14²-2(30)(14)cos125

x²  = 900 + 169 - 840cos125

x²   = 1069 - 840(-0.5735)

x² = 1069 +481.80

x² = 1,550.80

x =39.4

3) 28² = 18²+12²-2(18)(12)cosx

784 =  324 + 144- 432cosx

784 - 468 = - 432cosx

316 = - 432cosx

Cos x = -316/432

x = - 42.99

x = 180 - 42.99

x = 137.0 degrees

4) Using the sine rule

20/sinx = 33/sin91

33sinx = 20sin91

sinx = 20sin91/33

sinx = 19.997/33

sinx = 0.6059

x = arcsin(0.6059)

x = 37.3degrees

Answer:

Total cost= $41.83

Step-by-step explanation:

Giving the following information:

Purchase price= $39

Tax rate= 7.25% = 0.0725

To calculate the total cost of the pair of shoes, we need to use the following formula:

Total cost= purchase price * (1 + tax rate)

Total cost= 39 * 1.0725

Total cost= $41.83
