Bryan is sitting on a bench in the mall. He noticed that 18 out of the last 60 men who walked by had a beard. Considering this data, how many of the next 90 men who walk by should Bryan expect to have a beard?

Answer:

15•4 mm

Step-by-step explanation:

using sine rule

a÷ sinA=c ÷sinC

15•4÷sin90=0•5÷sinC

sinC =0•5 × sin90 ÷ 15•4

C =1•9°

A+B+C= 180

90+B+1•9=180

B= 88•2°

b÷sinB = a÷sinA

b÷sin88•2= 15•4÷sin90

b=sin88•2 ×15•4 ÷sin90

b =15•39

to 1 dp

b =15•4 mm

Answer:

A

Step-by-step explanation:

The slope is 2/5. Plug in the points and slope into the slope- intercept form y-y1=m(x-x1).

It would be...

y-4=2/5(x+2)

Answer: John ran 10 miles through Monday and Wednesday.

Step-by-step explanation: He ran for miles on 4 but 4 more than Monday and he ran 3 miles on Monday, so you add 4 + 3 which = 7 then you add 3 to 7 because he ran 3 miles on Monday then you get 10.

Answer:

16................

Step-by-step explanation:

Above

Answer:

The answer is 16.

Step-by-step explanation:

Negatives can be tricky, but once you get the hang of it, it will be much easier! The rule to remember here is:

"Anything 'minus a negative' just means plus, because the negatives cancel each other out."

a. For example, 4 -(-1) is the same thing as 4+1, which equals 5.

b. In this problem, 12-(-4) is the same thing as 12+4, which equals 16.

What is a sinusoidal wave?

Alternatively called a sine wave is a type of wave that shows a repetitive pattern or oscillation, it normally starts from a low point moves to the next point which is usually higher than the previous and repeats itself as the whole process continues

Answer:

Perimeter = 10

Step-by-step explanation:

Horizontally 3 units; vertically 2 units.

If h is horizontal measure, and v is vertical measure, then perimeter is 2(h+v) and area is hv.

[4] The Perimeter of the rectangle is how many units?

Perimeter formula ; 2(h+v)

2(3+2) = 10

Hey there!

Step 1: Calculate percentage

Since 30% of the marbles are green

=> 80 × 30/100

=> 8 × 30/10

=> 240/10

=> 24

So, 24 of the marbles are green

Step 2: Substract 24 from 80

=> 80 - 24

=> 56

Therefore, 56 marbles are not green

Answer:

y= [tex]\frac{72}{5}[/tex] or 14.4

Step-by-step explanation:

[tex]\frac{5}{6}y = 12\\[/tex]

Multiply both sides by 6/5, the reciprocal of 5/6.

[tex]y = 12 * (\frac{6}{5} )[/tex]

Express 12 x (6/5) as a single fraction.

[tex]y = \frac{12 * 6}{5}[/tex]

Multiply 12 and 6 to get 72.

[tex]y = \frac{72}{5}[/tex]

Answer: C or 6/5

Step-by-step explanation: the question is 4/5 plus 2/5 so 6/5

Integer, rational number, and real number

Step-by-step explanation:

Integer is a number that can be either positive or negative, but can't be a fraction or irrational number such as pi. It's also a subset of rational numbers, which is a subset of real numbers.

Answer:

[tex]\dfrac{\pi }{2}[/tex]

Step-by-step explanation:

The period of the function is from one peak to the next (or from one trough to the next).

[tex]\sf \implies period=\dfrac{\pi }{2}[/tex]

**see attached for the measurement of the period for this function**

Since the dilation is centered at the origin, you can multiply each of the coordinates by the scale factor. This means the image is A'(-6, -6)

Answer:

The 25th term is 97

Step-by-step explanation:

The explicit rule is f(n)=4n-3

Let f(n) = 97

97 = 4n-3

Add 3 to each side

97+3 = 4n-3+3

100 = 4n

Divide by 4

100/4 = 4n/4

25 = n

We are given that ,

[tex]{:\implies \quad \sf \dfrac{12+\sqrt{128}}{1-\sqrt{2}}=a+b\sqrt{2}}[/tex]

Consider LHS;

[tex]{:\implies \quad \sf \dfrac{12+\sqrt{128}}{1-\sqrt{2}}}[/tex]

Can be further written as ;

[tex]{:\implies \quad \sf \dfrac{12+8\sqrt{2}}{1-\sqrt{2}}}[/tex]

Rationalizing the denominator we have ;

[tex]{:\implies \quad \sf \dfrac{12+8\sqrt{2}}{1-\sqrt{2}}\times \dfrac{1+\sqrt{2}}{1+\sqrt{2}}}[/tex]

[tex]{:\implies \quad \sf \dfrac{(12+8\sqrt{2})(1+\sqrt{2})}{(1-\sqrt{2})(1+\sqrt{2})}}[/tex]

[tex]{:\implies \quad \sf \dfrac{12(1+\sqrt{2})+8\sqrt{2}(1+\sqrt{2})}{1-2}}[/tex]

[tex]{:\implies \quad \sf \dfrac{12+12\sqrt{2}+8\sqrt{2}+16}{-1}}[/tex]

[tex]{:\implies \quad \sf \dfrac{28+20\sqrt{2}}{-1}}[/tex]

[tex]{:\implies \quad \sf -28-20\sqrt{2}}[/tex]

Hence, we can conclude that ;

Answer: 25 feet

Step-by-step explanation:

If you place a 37 foot ladder against the top of a 12 food building, since 37 is greater than 12 the ladder will keep going past the building.

37-12=25

the ladder will be 25 feet from the bottom of the building
