Jlenok [28]3 years ago

Answer:

C

Step-by-step explanation:

Since every side of ΔABC is dilated by 3, or triple the size

We multiply every length of ΔABC by 3

But the length of DF and FG are already done for us but DG is not, which is essential to finding the answer

7 x 3 = 21

DG = 21

5/7 = 15/21

5 ÷ 7 = 0.71

15/21 = 0.71

5/7 = 15/21

The complete question in the attached figure

we know that
[<span>amount of fabric]=8*[area of lateral triangle side]
area of lateral triangle side=(1/2)*4*5----> 10 ft</span>²
so
[amount of fabric]=8*[10]----> 80 ft²

the answer is

Fencing How much fencing is required to enclose a circular garden whose radius is 28 ​m? Use 3.14 for . About nothing m of fenci
Andru [333]

Answer:

175.84 m

Step-by-step explanation:

Given that:

A circular garden which has a radius of 28 m.

\pi = 3.14

To find:

The fencing required to enclose the circular garden ?

Solution:

Here, we are given a circle and its radius.

We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..

Formula for finding the perimeter of a circle is:

Perimeter = 2\pi r

where r is the radius of the circle.

Using the given values in the formula:

Perimeter = 2\times 3.14 \times 28 = <em>175.84 m</em>

Therefore, 175.84 m of fencing is required.

I need help with this did I get this right
Scrat [10]
You’re very close! This is a triangular prism which means that the triangle portion has a unique formula. In order to find area of the triangle you do (base x height) and then divided by 2. In this case, base=6 and height=5 so 6x5=30 and 30 divided by 2 is 15. Then multiply by the length which is 10. The final answer is 150cm cubed.

Write 85% as it's fraction, as simply as possible​
cricket20 [7]

Hey ! there

Answer:

  • Simplest fraction form of 85% is <u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>.</u>

Step-by-step explanation:

Question says that we have to write the <u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>as </u><u>it's </u><u>fraction</u><u> </u><u>.</u>

<u>Solution </u><u>:</u><u> </u><u>-</u>

\quad \longrightarrow  \qquad \:85\%

We know that ,

  • Percent ( % ) = <u>1</u><u>/</u><u>100</u>

So ,

\quad \longrightarrow  \qquad \: 85 \times \dfrac{1}{100} \:

or ,

\quad \longrightarrow  \qquad \: \dfrac{85}{100}

Reducing the fraction by cancelling it by 5 :

\quad \longrightarrow  \qquad \: \dfrac{ \cancel{85}}{ \cancel{100}}

We get :

\quad \longrightarrow  \qquad \:      \pink{\underline{\boxed{\frak{\dfrac{17}{20} }}}} \quad \bigstar

Now , we can't reduce 17/20 .

  • <u>Henceforth</u><u> </u><u>,</u><u> </u><u>1</u><u>7</u><u>/</u><u>2</u><u>0</u><u> </u><u>is </u><u>the </u><u>simplest</u><u> </u><u>form </u><u>of </u><u>8</u><u>5</u><u>%</u><u> </u><u>.</u>
