3/8 of pupil in year 9 say their favourite colour is red there are 136 pupil in year 9 how many students said red is their favourite colour

Answer:

the answer is c

Step-by-step explanation:

The relationship between the lengths of the sides of the triangle is as follows: r² =  t² - s².

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The right triangle is given in the question, as shown

As per the given figure, the right triangle has

The hypotenuse = t

Let, perpendicular = r and base = s

According to Pythagoras's theorem,

In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

So, perpendicular²+base²=hypotenuse²

⇒ r² + s² =  t²

This can be rewritten as

⇒ r² =  t² - s²

Hence, the correct answer would be an option (A).

Answer:

1056 inches

Step-by-step explanation:

Given that :

Initial measurement = 2358 in

Guage level after 5 days of rain (final reading) = 3414 in

Change in water level rise :

Final reading - Initial reading

(3414 - 2358) in

= 1056 inches

Answer:

its 60

Step-by-step explanation:

if its right caan i get a brainliest

Answer:

60

Step-by-step explanation:

To get the area of a right triangle (a triangle with an angle of 90 [represented by the box in the corner]) you have the formula of

Area = (a*b) divided by 2

a = one side of the triangle

b = another side of the triangle

Neither side are the hypotenuse.

r = radius of circle

Step-by-step explanation:

The circumference of a circle is given by :

C = 2πr

Where

r is the radius of the circle

In this problem, we need to say that what does r represents in the given formula. It means we can say that r stands for the radius of the circle.

Answer:

Ali 25

Beth 15

Clare 32

Step-by-step explanation:

Here, we want to get the score of the three

let Ali’s score be x

He scored 10

more than Beth; Beth score will be x-10

Let us now work with the ratio

x/x-10 = 5/3

3x = 5(x-10)

3x = 5x - 50

5x-3x = 50

2x = 50

x =

50/2

x = 25

Beth will

score 25-10 = 15

score had 7 more than Ali,

25 + 7 = 32

y=25x+4

Answer:

[tex]x \approx 24\degree [/tex]

Step-by-step explanation:

In triangle BAC, by Pythagoras theorem:

[tex]AC^2 = BC^2 -BA^2 [/tex]

[tex]AC^2 = (15)^2 -(9)^2 [/tex]

[tex]AC^2 = 225 - 81[/tex]

[tex]AC^2 = 144[/tex]

[tex]AC = \sqrt {144} [/tex]

[tex]AC = 12\: cm [/tex]

In triangle ABD,

[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]

[tex] \tan \angle ABD =\frac{5}{9} [/tex]

[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]

[tex] \angle ABD =29.054604099\degree [/tex]

[tex] \angle ABD =29.05\degree [/tex]

Next, in triangle ABC, by sine rule:

[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]

[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]

[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]

[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]

[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]

[tex]29.05\degree+x =53.130102354\degree [/tex]

[tex]29.05\degree+x =53.13\degree [/tex]

[tex]x =53.13\degree- 29.05\degree[/tex]

[tex]x =24.08\degree [/tex]

[tex]x \approx 24\degree [/tex]

Answer:

y=3-x

Step-by-step explanation:

Answer:

First we get y on one side by itself.

5x+5y=15

We move x over to the other side.

5x-5x+5y=15-5x

Simplify.

5y=15-5x

Now we remove the coefficient from y.

5y/5=(15-5x)/5

Simplify.

y=15/5-5x/5

y=3-x

The answer is y=3-x

Answer:

Numbers are 29 and 34

Step-by-step explanation:

Let x = one number

let y = second number

x + y = 63

x - y = 5

substitution method, x = 5 + y

5 + y + y = 63

2y + 5 = 63

2y = 58

y = 29

Find value of x:  x - 29 = 5

x = 34
