What is the value of x in this figure?

Mathematics

Given that the triangle is an isosceles right angled triangle, then the value of x will obtain using the Pythagorean theorem, given by:
c^2=a^2+b^2
where
c is the hypotenuse, a and b are the legs
thus
x^2=12^2+12^2
x^2=144+144
x^2=288
hence
x=√288
x=√(2×144)
x=2√12

Leona [35]
2.75%= convert it to a decimal

.0275

Now, multiply that by 20.

20*.0275= 0.55 

0.55 is 2.75% of 20.

I hope this helps!

The population of Bridgetown triples every decade. If the population
Afina-wow [57]
Between 2000 and 2030 three decades will have gone by, which means the population will triple three times.

2000-25,000 \\ 2010-25,000*3=75,000 \\ 2020-75,000*3=225,000 \\ 2030-225,000*3=675,000

Therefore, the population of Bridgetown will be 675,000 people in 2030.

18. what is the midpoint of PQ P(-2, 2.5), Q(1.4, 4)​
scoray [572]

Mid point of the points PQ is (₋0.3 , 3.25)

Given points are:

P(₋2 , 2.5)

Q(1.4 , 4)

midpoint of PQ = ?

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.

The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.

Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)

we have two points:

P(₋2,2.5) = (x₁,y₁)

Q(1.4,4) = (x₂,y₂)

Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)

= (₋0.6/2 , 6.5/2)

= (₋0.3 , 3.25)

Hence we determined the midpoint of PQ as (₋0.3 , 3.25)
