What is the value of value of 5/6 ÷ 3/4?​

Answers

Answer:

answer is 10/9

:-)))☺️☺️

I hope it helps you

Answer: 1 and 1/9

Step-by-step explanation: Here, we have 5/6 ÷ 3/4.

Dividing by a fraction is the same as multiplying by its reciprocal.

In other words, we can change the division

sign to multiplication and flip the second fraction.

So here, 5/6 ÷ 3/4 can be rewritten as 5/6 × 4/3.

Now we're simply multiplying fractions so we multiply across the

numerators and multiply across the denominators.

So we have 5 × 4 which is 20 and 6 × 3 which is 18.

Notice that 20/18 is not in lowest terms so we divide the

numerator and the denominator of 20/18 by 2 to get 10/9.

If you would like, you can change this to the mixed number 1 and 1/9

by simply dividing 9 into 10 and putting the remainder over the denominator.

Robert is pouring wax into cylindrical candle containers. Approximately 226.19 cubic inches of wax fill one candle jar. Which image represents that volume?

A cylinder with height 8 inches and radius 3 inches.
A cylinder with height 5 inches and radius 4 inches.
A cylinder with height 10 inches and radius 2 inches.
A cylinder with height 5 inches and radius 5 inches.

Answers

Answer:

The first choice.

Step-by-step explanation:

The volume must be about 226.19 in^3.

Volume of a cylinder = area of base * height4

= πr^2h  = 226.19

r^2 = 226.19 / πh.

Consider the first of the choices:-

When h = 8 , r^2 = 226.19 /8π = 8.9998

So r = 3.00  to nearest hundredth.

So this is the required image.

Answers

Answer:

1. $85

2. $90.10

3.$108.12

4.$54.06

Step-by-step explanation:

100-15=85 (15% of 100 is 15)

6 percent of 85 is 5.10. So 85 + 5.10=90.10

20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12

Now divide by 2 to get how much they each will pay 108.12/2 = 54.06

Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer. What was the total amount of money Daniel found?

Answers

Answer:

303 cents.

Step-by-step explanation:

Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer

We know that, dollar is equal to 100 cents

2 dollars = 200 cents

It means, Daniel found 9 cents in his backpack, 89 cents in the couch, and 200 cents and 5 cents in the drawer.

Price = 9+89+200+5

= 303 cents

Hence, Daniel found 303 cents.

Answers

The transformation is better described by:  Triangle A B C is reflected across line m and then is dilated to form smaller triangle A double-prime B double-prime C double-prime

What is transformation?

In mathematics, transformation is manipulating a figure on a plane or coordinate system.

In this case the manipulation involves reflection and scaling to a factor between 0 and 1

scaling to factor 0 means the triangle disappeared

scaling to factor 1 means the triangle remained same size

factors between 0 and 1 means reduction of size.

since the transformation did not rotate the triangle it makes the first option the correct answer

A painter leans a 30 foot ladder against one wall of a house. At what height
does the ladder touch the wall if the foot of the ladder is 10 feet from the base
of the wall?

Answers

Answer:

20ft

Step-by-step explanation:

The height at which the ladder touch the wall when the ladder is 30 feet long, and the ladder is 10 feet from the base of the wall is 20√2 feet.

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Consider the diagram below.

We've got:

Length of the ladder = |AC| = 30 ftDistance between ladder's bottom and base of wall = |BC| = 10 ftHeight of wall from base to the point where ladder touches = |AB| is to be known.

The wall is usually perpendicular to ground, therefore making 90° angle with it. Thus, ABC is a right angled triangle.

Using Pythagoras theorem in it, we get:

[tex]|AC|^2 = |AB|^2 + |BC|^2\\\\30^2 = |AB|^2 + 10^2\\|AB|^2 = 900 - 100\\\\|AB|^2 = 800\\\\\text{Taking sq. root of both the sides}\\\\|AB| = \sqrt{800} = \sqrt{ (\pm 20\sqrt{2})^2}\\\\|AB| = \pm 20\sqrt{2} \: \rm ft[/tex]

But as length cannot be a negative quantity, so we get:

[tex]|AB| = 20\sqrt{2} \: \rm ft[/tex]

Thus, the height at which the ladder touch the wall when the ladder is 30 feet long, and the ladder is 10 feet from the base of the wall is 20√2 feet.
