Lucy makes 4/7 of a dress in 3/4. How many dresses does she make in one hour
GREYUIT [131]

Answer:

3/7 of a dress in one hour

Step-by-step explanation:

(4/7)/(3/4)=x/(4/4)

(4/7)(4/3)=x/1

cross product

4/3*x=(4/7)(1)

4/3x=4/7

x=(4/7)/(4/3)

x=(4/7)(3/4)

A total of 8,844 people went to the football game.
Alex787 [66]

Number of people sat in each section on visitor side is equal to 468

<u>Solution:</u>

Given that  

Total number of people went to football game = 8844

Also given 5,100 sat on the home side and the rest sat on  the visitor'a side.

Means Number of people sat on the home side = 5100

And remaining Number of people sat on the visitor side = Total number of people went to football game - Number of people sat on the home side

= 8844 – 5100 = 3744

Also given people sitting on the visitor's side filled 8 equal-sized sections

Need to calculate people sat in each section that is number of people on side in 1 section.

As calculated , total number of people sitting in equally sized 8 sections on visitor side = 3744

=> number of people sitting in 1 section on visitor side = \frac{3744}{8}=468

Hence 468 people sat on each section

What is the perimeter of an equilateral triangle that has a height of 24m?
meriva

Answer:

The perimeter of an equilateral triangle that has a height of 24m is

Option C : 48 square root 3

Step-by-step explanation:

Given:

Height of the triangle =24 m

To Find:

The perimeter of an equilateral triangle  = ?

Solution:

Perimeter of the equilateral  triangle  =  3a

where a is the side of the triangle

Here the height is given as 24 m

Then from the figure

Sin(60^{\circ}) = \frac{opposite}{hypotenuse}

Sin(60^{\circ}) = \frac{24}{x}

x = \frac{24}{Sin(30^{\circ})}

x= \frac{24}{\frac{\sqrt{3}}{2}}

x = \frac{24 \times2}{\sqrt{3}}

x = \frac{48}{\sqrt{3}}

Now

The perimeter is

=> 3x

=>3 \times \frac{48}{\sqrt{3}}-------------------------(1)

Now we know that 3 = \sqrt{3} \times \sqrt{3}--------------------(2)

Substituting (2) in (1)

=>(\sqrt{3} \times \sqrt{3}) \times \frac{48}{\sqrt{3}}

=>48\sqrt{3}
