Your Answer is 84

Let x = the 10's digit, and y = the units digit

Write an equation for each statememt

"sum of the digit of two digit no. is 12."

x + y = 12

or

y = 12 - x; we use this for substitution, if needed

"the given no. exceed the no. obtained by interchange the digit by 36."

Given number: 10x + y

interchanged number: 10y + x

The equation from the given statement:

10x + y = 10y + x + 36

Some simple algebra:

10x - x = 10y - y + 36

9x = 9y + 36

Simplify, divide equation by 9

x = y + 4

Substitute (12-x) for y, (from the 1st statement)

x = (12-x) + 4

x + x = 12 + 4

2x = 16

x = 8

y = 12 - 8 = 4

Our number is 84:

Check it: 84 - 48 = 36

Will give brainliest and 5stars and thank you if youre answer is right
slega [8]

Step-by-step explanation:

since

25⁰= 1 minute

x⁰ = 11 minutes

cross multiply

25 x 11= x

x= 275⁰

temperature after being turned on=275⁰

temperature after 11 minutes= 275⁰ + 75⁰= 350⁰

temperature(x) after being turned on

25tt=x

temperature (x) after minutes

x= 25tt + 75⁰

Exercise questions
balu736 [363]

Answer:

2.

a)1

b)1

c)1

Step-by-step explanation:

There's some identity trigonometric equation, which are valid for all angles,and they doesn't depends on the measure of angle!

some of em are follows:. (x is the given angle)

  • sin(x)^2+cos(x)^2=1
  • cosec(x)^2=1+cot(x)^2
  • sec(x)^2=1+tan(x)^2

You can remember these identity, its gonna help alot.

now back to question,. {x is representing angles)

for (a) sin(x)^2+cos(x)^2=1, this is true for all x, dat means that for all the angle given in question(for ,15°,30°,45°,60° and 120°),we will get 1

for(b) ,

cosec(x)^2=1+cot(x)^2

i.e, cosec(x)^2-cot(x)^2=1, again this is true for all x dat means that for all the angle given in question ,we will get 1

for (c),

sec(x)^2=1+tan(x)^2

i.e,sec(x)^2-tan(x)^2=1,again this is true for all x, dat means that for all the angle given in question ,we will get 1

Manuel wants to build a model of Captain America's famous shield out of cardboard. The outer ring of the shield is colored red.
zmey [24]

Answer:

615.44 in²

Step-by-step explanation:

The shape of Captain America's shield = Circular

The area of a circle = πr²

The radius of the whole shield = 14 inches.

The first ring = Red ring

Hence, the area of the red ring =

π = 3.14

3.14 × 14²

= 615.44 in²

The area of the space he needs to paint red is 615.44 in²
