Salutations!

Which of the following is an example of a proper fraction?

3/4 is a proper fraction. Proper fractions are fractions that have a number that is smaller numerator and greater denominator. 7/6 and 4/3 are improper fractions. Improper fractions are fractions that have a greater numerator and a smaller denominator. 4/4 is a like fraction. Like fractions are fractions that have alike numbers in both numerators and denominators.

Thus, your answer is option D.

Hope I helped (:

Have a great day!

Find the distance between the given points: (2, -2) and (-4, 7)

sasho [114]

Answer:

$3\sqrt{13}$

Step-by-step explanation:

Hi there!

We want to find the distance between the points (2, -2) and (-4, 7).

To do that, we can use the distance formula.

The distance formula is given as $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have everything needed to find the distance, but let's label the values of the points to avoid any confusion

$x_1=2\\y_1=-2\\x_2=-4\\y_2=7$

Now substitute those values into the formula and solve

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\sqrt{(-4-2)^2+(7--2)^2}$

Simplify

$\sqrt{(-4-2)^2+(7+2)^2}$

$\sqrt{(-6)^2+(9)^2}$

Square the numbers under the radical

$\sqrt{36+81}$

Add the numbers under the radical together

$\sqrt{117}$

Simplify the square root

$3\sqrt{13}$

Hope this helps!

Solve this problem using the Trigonometric identities (secA+1)(SecA-1)= tan^2A

sammy [17]

Step-by-step explanation:

( secA + 1)( sec A - 1)

Using the expansion

( a + b)( a - b) = a² - b²

Expand the expression

We have

sec²A + secA - secA - 1

That's

sec² A - 1

From trigonometric identities

<h3>sec²A - 1 = tan ²A</h3>

So we have the final answer as

<h3>tan²A</h3>

As proven

Hope this helps you

Priya is stacking building blocks to make a tower. She takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the

tensa zangetsu [6.8K]

Answer:

4 feet.

Step-by-step explanation:

Let x be the height of tower when finished.

We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.

This means that 5/8 of x equals $2\frac{1}{2}$ . Let us represent this information in an equation.

$\frac{5}{8}*x=2\frac{1}{2}$

Let us convert our given mixed fraction into improper fraction.

$\frac{5}{8}*x=\frac{5}{2}$

Let us multiply both sides of our equation by 8/5.

$\frac{8}{5}\times \frac{5}{8}*x=\frac{5}{2}\times \frac{8}{5}$

$x=\frac{8}{2}$

$x=4$

Therefore, the tower will be 4 feet tall when finished.
