Find the area of the parallelogram that has a base of 2 1/2 ft and a height of 1 1/4ft

Marina CMI [18]

Answer:

The area of the parallelogram is $3\frac{1}{8}ft^{2}$

Step-by-step explanation:

Remember that a mixed fractions are composed for a whole number, a numerator and a denominator. For example in the mixed fraction $2\frac{1}{3}$ : 2 is the whole number, 1 is the numerator and 3 is the denominator.

If you want to convert to a improper fraction you need to multiply the whole number by the denominator and add to the numerator. The result will be the numerator of the improper fraction. The denominator remains the same.

$2\frac{1}{3}=\frac{(2*3)+1}{3} =\frac{7}{3}$

1. Convert the mixed fractions in the improper fraction type, as follows:

$Base= 2\frac{1}{2}=\frac{5}{2} \\ \\Height= 1\frac{1}{4}=\frac{5}{4}$

2. Replace the data in the equation of a parallelogram

$Area= Base*Height$

$Area= Base*Height\\Area=\frac{5}{2}ft *\frac{5}{4}ft\\Solve...\\Area=\frac{25}{8}ft^{2}$

3. Convert the improper fraction in a mixed fraction

$Area=\frac{25}{8}ft^{2}=3\frac{1}{8}ft^{2}$

The area of the parallelogram is $3\frac{1}{8}ft^{2}$

50 POINTS. A ball is thrown into the air from a height of 4 feet at time t = 0. The function that models this situation is h(t)=

Morgarella [4.7K]

Answer:

The domain that makes sense for this function is all values greater than or equal to 0.

Step-by-step explanation:

A ball is thrown into the air from a height of 4 feet at time <em>t</em> = 0. It is modeled by the function:

$h(t)=-16t^2+64t+4$

The domain of the function is time <em>t</em>. The range of the function is the ball's height in the air <em>h</em>.

Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.

Therefore, the domain that makes sense for this function is all values greater than or equal to 0.

In interval notation, this is:

$[0, \infty)$

And as an inequality:

$t\geq 0$

Quiero realizar ese ejercicio 10x + 8 = 2 - 2x

olasank [31]

Answer:

x=-1/2

Step-by-step explanation:

Move -2x to the other side by adding 2x on both sides:

12x+8=2

Move 8 to the other side by subtracting by 8 on both sides:

12x=-6

Divide by 12 on both sides:

x=-1/2

Hope this helps!
