The total amount of degrees in a triangle is 180. All three angles should add up to 180˚

We know that 40+60 = 100

The next step is to do 180-100 to get the other angle.
180-100 = 80

So the measure of the third angle is 80˚

Hope this helps!

(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)

Using the formula: A=p(1+r)t How much money will Mario have if he puts $1000 in a savings account earning 4% annually after 10 y

steposvetlana [31]

Answer:

The amount is $1480.24

Step-by-step explanation:

We are given

he puts $1000 in a savings account earning 4% annually after 10 years

so,

P=1000

r=4%=0.04

t=10

now, we can use formula

$A=P(1+r)^t$

now, we can plug values

$A=1000(1+0.04)^{10}$

$A=1480.24428$

So,

The amount is $1480.24

The area of a tiled kitchen floor is represented by the expression 4x2 + 24x + 27, where x represents the length of a single til

Readme [11.4K]

Let
x--------> represents the length of a single tile
L-------> the length of the floor
W------> the width of the floor
A--------> area of a tiled kitchen floor

we know that
A=W*L
A=4x² + 24x + 27
so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2

substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]

therefore

the answer is
the expression that represents the width of the kitchen in terms of x is
W=[4x² + 24x + 27]/[2x+9]
