In mathematics, a ratio indicates how many times one number contains another. ... When two quantities are measured with the same unit, as is often the case, their ratio is a dimensionless number. A quotient of two quantities that are measured with different units is called a rate.
The answer is the third one
-the hours are unknown so its 6+4h
the total is 130 and she earns an extra 20 dollars so
(6+4)h+20=130
Answer:
The volume of the right rectangular prism is 592.2cm³
Step-by-step explanation:
To calculate the volume of a rectangular prism we have to multiply the area of the base by the height
a = area of the base = 84.6cm²
h = height = 7cm
v = volume
v = a * h
v = 84.6cm² * 7cm
v = 592.2cm³
The volume of the right rectangular prism is 592.2cm³
In mathematics, a polynomial is an algebraic expression containing more than two terms. When the polynomial could not be reduced to a lower degree, it is classified as a prime polynomial. Just like whole numbers, a prime polynomial cannot be broken down into factors except 1 and by the number itself. Take for example, the polynomial x² + 5x + 6. It can be reduces to its factors x=-2 and -3. That would be expressed to x² + 5x + 6 = (x+2)(x+3). But if the polynomial is, say, x² + 5x + 7, there is no roots that are whole numbers. Therefore, it can't be reduced into factored groups because it is a prime polynomial.
If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²
so we are given
the legs are x and √7
and the hypotnuse is √19
so
x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
