And that's it! :)

Answer:

5/21

Step-by-step explanation:

Here is a strategy I want you to remember: Keep, Change, Flip. What do I mean by that? Well...

Keep the first fraction. Change the division sign into a multiplication sign. Make the numerator of the second fraction become the denominator--and make the denominator of the second fraction become the numerator.

The denominator of any whole number is always 1. So, 7 equals to 7/1. Time to find the reciprocal of 7/1! What does reciprocal mean?

Reciprocal - Flip the fraction in terms of the numerator and denominator; Multiplicative Inverse

1/7 is the reciprocal of 7/1, for this mathematical problem. Makes sense, right?

Now, 5 times 1 equals 5 (that is the numerator). Secondly, 3 times 7 equals 21 (that is the denominator).

The initial number of party favor bags Razee had to fill were 48 bags.

Here, we will use arithmetic progression to solve this problem.

We are given that:

At 4 minutes, 36 bags were remaining.

At 5 minutes, 32 bags were remaining.

At 6 minutes, 28 bags were remaining.

At 7 minutes, 24 bags were remaining.

This can also be written as:

a₄ = a + 3d = 36

a₅ = a + 4d = 32

a₆ = a + 5d = 28

a₇ = a + 6d =24

where a is the initial number of party favor bags.

a₅ - a₄ = a + 4d - a - 3d

a + 4d - a - 3d = 32 - 36

d = -4

a + 3d = 36

a + 3(-4) = 36

a - 12 = 36

a = 36 + 12

a = 48

Therefore, the initial number of party favor bags Razee had to fill were 48 bags.

The time taken by the plain if it flies at a speed of 800 km/h is 6 hours 45 minutes

Given,

Time taken by plain to fly from Los Angeles to New York = 6 hours

Speed of plain = 900 km/h

We have to determine the time taken by the plain if it flies at a speed of 800 km/h

Distance cover by plain = speed x time = 900 x 6

Distance cover by plain = 5400 kilometer

New time taken by plain = Distance cover by plain / New speed of plain

New time taken by plain = 5400 / 800

New time taken by plain = 6 hours 45 minutes

That is, the time taken by the plain if it flies at a speed of 800 km/h is 6 hours 45 minutes

An algebraic expression to represent the perimeter of the isosceles triangle with base length x - 10 and legs of length x is equal to y = 3x -10.

As given,

In isosceles triangle

Base length=x - 10

Length of the legs=x

Let y be perimeter of the triangle

Algebraic expression is

Perimeter of isosceles triangle =sum of all the legs length

⇒y=x - 10 +x + x

⇒y=3x -10

Therefore, an algebraic expression to represent the perimeter of the isosceles triangle with base length x - 10 and legs of length x is equal to

y = 3x -10.

A triangle's opposite side is split in half by an angle bisector into two segments that are proportional to the other two sides.

We can solve this problem by using the formula explained in the angle bisector theorem below.

Angle Bisector theorem :

            In the below image, PS is the angle bisector of ∠P in ΔPQR.

As a result, we can state that by using the angle bisector theorem as

PQ/PR = QS/SR

or

a/b = x/y.

By this, we can solve the angle bisector theorem.

`x-0.1x+2.70=56.70

Answer:

Step-by-step explanation:

To solve this equation

x-0.1x+2.70=56.70

We first find like terms and then subtract both sides of the equation

x-0.1x+2.70=56.70= 1x-0.1x+2.70=56.70

Add like terms

0.9x+2.70=56.70

Subtract both sides of equation

0.9x=56.70-2.70

Divide both sides

0.9x=54

x=54/0.9
