PLEASE HELP ME PLEASE (10 mins)

Mathematics
1 answer:
NeX [460]3 years ago
5 0

Answer:

Step-by-step explanation:

1) When the sector is cut out, the remaining sector would be used to form the cone. The angle subtended by this sector would be

360 - 60 = 300°

The length of the arc of this sector would represent the circumference of the circular base of the conical hat.

Radius of the circle = diameter/2 = 20/2 = 10 inches

Formula for length of arc = #/360 × 2πr

Where

# is the subtended angle

Therefore,

Length of arc = 300/360 × 2 × 3.14 × 10 = 52.3 inches

circumference of the circular base of the conical hat = 52.3 inches

2) the surface area = πrl

Where

l represents the slant height

the radius of the circle would become l.

To determine the radius of the cone, we would apply, we would make use of the circumference of the circular base.

Circumference = 2πr

52.3 = 2 × 3.14 × r

r = 52.3/6.28 = 8.33 inches

Surface area = 3.14 × 8.33 × 10 = 262 inches²

A transformation T: (x, y) (x + 3, y + 1). For the ordered pair (4, 3), enter its preimage point. (-1, 2) (1, 2) (7, 4)
Aleksandr-060686 [28]

Answer:

(1,2)

Step-by-step explanation:

we know that

The rule of the transformation is equal to

(x, y)  ------> (x + 3, y + 1)

Pre-image -----> Image

(x, y)  ------> (4, 3)

so

x+3=4 ----> x=4-3=1

y+1=3 ---> y=3-1=2

therefore

The pre-image is the point (1,2)

Endeye needs to split 1/5 of the dinner left over from last week to feed her 3 siblings. What fraction of the original dinner wi
aleksandr82 [10.1K]

Answer:

<u><em>They each had </em></u><u><em>1/20 of the original meal</em></u>

Step-by-step explanation:

<u><em>To begin, </em></u><u><em>there are 4 people</em></u><u><em>. Her siblings, and herself. She is </em></u><u><em>splitting the 1/5 leftover</em></u><u><em> to feed them. To do this, we simply </em></u><u><em>take 1/5 and put it into a fraction to get 0.2</em></u><u><em>. Next, we can </em></u><u><em>put 0.2 / 4 into a calculator</em></u><u><em> to get how much each person can get.</em></u>

<u><em>0.2 / 4 = 0.05.</em></u>

<u><em>Now, we need to </em></u><u><em>turn it into a fraction</em></u><u><em> to find out how much they had in fraction form of the original.</em></u>

<u><em>0.05 = 1/20</em></u>

<u><em>They each had </em></u><u><em>1/20 of the original meal</em></u>

What is the solution to 6x=30
Tasya [4]

Answer:

\boxed{x=5}

Step-by-step explanation:

Division property of equality- is dividing both sides of an equation by the same non-zero number it does not change the equation.

First you had to divide by six from both sides of an equation form.

\frac{6x}{6}= \frac{30}{6}

30/6=5

30/5=6

5*6=30

6*5=30

x=5

5=x

Final answer: \boxed{x=5}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
