Ifa rectangle measures 20 meters by 48 meters, what is

sasho [114]

Answer:

$52m$

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of the diagonal since drawing a diagonal across a rectangle results in two right angle triangles.

Length of diagonal $= \sqrt{20^2+48^2}$ (The length of the diagonal can be thought of as the hypotenuse of one of the right angle triangles)

$=\sqrt{2704}$

$=52 m$

∴ The length of the diagonal is $52 m$

Hope this helps :)

Anybody pls solve this question and explanation btw.

Answer:

$Vol=883.6875\,\, cm^3\\$

Step-by-step explanation:

Recall that the volume of a whole sphere is given by the formula:

$Vol_{sphere}=\frac{4}{3} \pi\,R^3$

then, the volume of a semi-sphere would be half of the formula above:

$Vol=\frac{2}{3}\, \pi\,R^3$

Now, the radius R is given by half of the semi-sphere diameter: 15/2 = 7.5 cm.

which makes our calculation:

$Vol=\frac{2}{3}\, \pi\,R^3=\frac{2}{3}\, \pi\,(7.5\,cm)^3=883.6875\,\, cm^3\\$

raj and his sister zia are both at secondary school. Raj is three years older than zia. the sum of the squares of their ages is

steposvetlana [31]

Let's assume

Raj's age is x years

Zia's age is y years

we are given

Raj is three years older than zia

so, we get

$x=y+3$

now, we can solve for y

$y=x-3$

the sum of the squares of their ages is 369

so, we get

$x^2+y^2=369$

now, we can plug back y

$x^2+(x-3)^2=369$

now, we can solve for x

$2x^2-6x+9=369$

$2x^2-6x-360=0$

$x^2-3x-180=0$

$(x+12)(x-15)=0$

$x=-12 , x=15$

Since, age can not be negative

so, we will only consider positive

$x=15$

now, we can find y-value

$y=15-3$

$y=12$

So,

Raj's age is 15 years

Zia's age is 12 years...........Answer

Please help it would mean a lot to me :)

Answer:

a) TO = OP = 13

b) Height = 12

Step-by-step explanation:

a) Isosceles triangle TOP with base TP = 10 cm, side TO = OP = x cm.

Perimeter of triangle TOP = 36 cm

=> TO + OP + TP = 36

=> x + x + 10 = 36

=> 2x = 26

=> x = 13

=> TO = OP = 13 cm.

b) Apply Pythagorean theorem:

height^2 + (base/2)^2 = side^2 (height^2 + (TP/2)^2 = TO^2)

height^2 + (10/2)^2 = 13^2

height^2 + 25 = 169

height^2 = 144

height = 12

Hope this helps!

What is the answer of -3 2/3 + 1.1 as a fraction?

pickupchik [31]

$- 3 \frac{2}{3} + 1.1 = - \frac{11}{3} + \frac{11}{10} = - \frac{110}{30} + \frac{33}{30} \\ = -\frac{77}{30} = -2 \frac{17}{30}$
