The measure of three angles of a triangle are (2×), (3×) and (×+60) what is the value of x ?

1 answer:

4 0

Since the sum of the angles of a triangle = 180°

Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20

The circumference of a circle is 19.8mm. Find the length of the radius. Give your answer rounded to 1 DP.

Effectus [21]

Circumference of a circle = 2pie*r
= 19.8=2*314*r/100
= 1980 = 628*r
r = 1980/628
r = 3.13
~= 3 cm^2

jok3333 [9.3K]

Answer:

The fraction of male student who play sport is $\frac{3}{4}$

Step-by-step explanation:

Given as :

Out of the total number of students , the fraction of male = $\frac{2}{3}$ of total number of students

Let the total number of students = x

So, The fraction of male student = $\frac{2}{3}$ of x

I.e The fraction of male student = $\frac{2 x}{3}$

Again

The number of students who play sports = $\frac{1}{2}$ of total number of students

Or, The number of students who play sports = $\frac{1}{2}$ of x

Or, The number of students who play sports = $\frac{x}{2}$

Let The total number of male student who play sport = y

So, According to question

$\frac{2 x}{3}$ of y = $\frac{x}{2}$

I.e $\frac{2 x}{3}$ × y = $\frac{x}{2}$

or, y = $\frac{\frac{x}{2}}{\frac{2 x}{3}}$

∴ y = $\frac{3}{4}$

So, The total number of male student who play sport = y = $\frac{3}{4}$

Hence ,The fraction of male student who play sport is $\frac{3}{4}$ Answer

(4^p*4^1)^3) =4^15

add the exponents

(4^(p+1))^3 = 4^15

multiply the exponents

(4^3(p+1))= 4^15

the exponents have to be the same

3(p+1) = 15

divide by 3

p+1 = 5

subtract 1

p =4

Eric is not correct

p=4
