Answer:
Expression.
Step-by-step explanation:An expression containing variables, numbers, and operation symbols is called an algebraic expression. is an example of an algebraic expression. Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
Answer:
Hey there!
We can't compare two measurements without converting them to the same units. Thus, we use proportions to make all the values into the same unit.
, which converts to centimetres to millimetres.
12.5 cm=125 mm.
Now, we can compare the values of 125 mm and 140 mm.
Clearly, we see that 140 mm is greater than 125 mm.
Let me know if this helps :)
I think you need to use the SoHCaHToA method here.
S means sin
C means cos
T means tan
O means opposite
H means hypotenuse
A means adjacent
The hypotenuse is the longest side in a right angled triangle.
The adjacent is the side between the angle and the right angle.
The opposite is the side that is left.
If you have the value of the opposite cross all of the o's out. The same with the other sides. If only one type of letter is crossed out, cross out the type of letter that stands for the length you want to find. The part of the word with two crosses tells you what function to use (sin, cos or tan)
In this example, the function used will be sin.
sinx°=o÷h
cosx°=a÷h
tanx°=o÷a
since we are using sin, the formula we will use is :
sinx°=o÷h
Then you plug in what you know.
sin30°=30÷h
h=30÷sin30°
h=60ft
If there was a case when you needed to work out an angle, inverse sin, or cos, or tan would be used.
For 1 cup of flour we need 2/3 teaspoons of vanilla.
For 5 cups of flour:
5 x 2/3 = 10/3 = 3 1/3 = 3.333...
Answer:
3 1/3 teaspoons.
That would be (k^2 y^2), or simply (ky)^2 .
