A square picture with a side length of 30 cm is scaled by 60% on a photocopier. The copy is then scaled by 60% again. What is the side length of the picture after it has been successively scaled by 60% 4 times?

Answers

Answer 1
Answer:
10.8 cm


Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that
60% =60/100 = .60

so The length of the first copy of the picture is
30(.60) = 18

2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is
18(.60)=10.8 cm

1. Brenda invited 32 people to her graduation party. If each person will drink about 3 cups of punch, how many gallons of punch does Brenda's mom need to buy?

Answers

Answer: 96

Step-by-step explanation: Its pretty simple all you have to do is 32*3 because there is 32 people and they all drink 3 cups fruit punch. SO the answer is 96.

The gallons of punch Brenda's mom needs to buy is  6 gallons.

How many gallons of punch should be bought?

The first step is to convert cups to gallons: 1 cup = 1/16 gallon

The second step is to determine the total number of cups needed for the party: 32 x 3 = 96 cups

Now convert the cups to gallons: 96 x 1/16 = 6 gallons

Answers

Answer:

about 4

Step-by-step explanation:

just guessed

The number of tablespoons of kernels to use to make 6 cups of popcorn will be 4 tablespoons. Option B is correct.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Serena makes 2 1/4 cups of popcorn using 1 1/2 tablespoons of kernels.

Convert the mixed fraction into a fraction number. Then we have

2  1/4 = 9/4

1  1/2 = 3/2

The ratio of cups of popcorn and tablespoons of kernels will be constant.

The number of tablespoons of kernels to use to make 6 cups of popcorn will be given as,

K / 6 = (3/2) / (9/4)

K = 4 tablespoons

The number of tablespoons of kernels to use to make 6 cups of popcorn will be 4 tablespoons. Option B is correct.

Step-by-step explanation:

They are angles on transversals intersecting parallel lines. Also vertical angels are equal to each other.

find the 9th term for 150,60,24

Answers

Answer:

a(9) = 150*(0.4)^8 = 0.098304

Step-by-step explanation:

This is a geometric sequence, because each new term is 0.4 times the previous term.

The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1).  Here, with a(1) = 150 and r = 0.4, we have:

a(n) = 150*(0.4)^(n - 1), and so

a(9) = 150*(0.4)^8 = 0.098304

The length of a rectangular deck is five times it's width if the decks perimeter is 24 feet what is the decks area

Answers

Answer:

20 square feet

Step-by-step explanation:

The length of a rectangular deck is five times it's width if the decks perimeter is 24 feet what is the decks area

Step 1

We find the Length and Width of the deck

Perimeter of a rectangle = 2L + 2W

The length of a rectangular deck is five times it's width

W = Width

L = Length = 5W

P = 24 feet

Perimeter = 2(5W) + 2W

24 = 10W + 2W

24 = 12 W

W = 24/12

W = 2 feet

Solving for L

L = 5W

L = 5 × 2 feet

L = 10 feet

Step 2

We find the area of the deck

Area of the deck(Rectangle) = Length × Width

= 10 feet × 2 feet

= 20 square feet

An individual ticket at Wild Waves has been marked down $30 to $26.40. A family pass has been marked down from $80 to $71.40. Which deal offers a

Answers

Answer:

  $30 ticket

Step-by-step explanation:

The cheaper ticket is 3/8 the cost of the expensive one. If the tickets have the same discount the discounted cheaper ticket would cost ...

  (3/8)($71.40) = $26.78

The cheaper ticket costs less than that, so the $30 ticket has a better discount.

Figuring the discount on each ticket is more work. I like to do as little work as possible. (If you do that work, you find the $30 ticket is discounted 12%, and the $80 ticket is discounted 10.75%.)

I hope this helps you!!

Step-by-step explanation:

In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.

At what point do the lines y = 6x – 18 and
y= 8x – 32 intersect?

Answers

Answer: The lines intersect at the point (7, 24)

Step-by-step explanation:

We have two lines:

y = 6*x - 18

y = 8*x - 32

We want to find the point at which both lines intersect, this means that there is a point (x, y) that belongs to both lines.

This means that we can write:

6*x - 18 = y = 8*x - 32

Because the y-value should be the same for both lines, then we get:

6*x - 18 = 8*x - 32

Now we can solve this for x.

6*x - 18 = 8*x - 32

32 - 18 = 8*x - 6*x

14 = 2*x

14/2 = x = 7

Now we know that the lines intersect at x = 7, replacing this in any of the two equations we can get the y value at which the lines intersect, let's use the first equation:

y  = 6*7 - 18 = 24

So the lines intersect at the point (7, 24)

There are 10 chocolates in a box.
7 of the chocolates have soft centres and 3 of the chocolates have hard centres. Kyla takes at random a chocolate from the box and eats it.
She then takes at random another chocolate from the box and eats it.

Answers

What’s the question?

The probability of getting chocolates with harder center is 7/15.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, there are 10 chocolates in a box. 7 of the chocolates have soft centers and 3 of the chocolates have hard centers.

Probability of choosing first chocolate with hard center is

Total number of outcomes =10

Number of favorable outcomes =7

Now, probability is 7/10

Probability of choosing second chocolate with hard center is

Total number of outcomes =9

Number of favorable outcomes =6

Now, probability is 6/9

Probability of an event = 7/10 × 6/9

= 7/10 × 2/3

= 7/5 × 1/3

= 7/15

Therefore, the probability of getting chocolates with harder center is 7/15.

Find the perimeter and the area of the polygon with the vertices: (-1, -2), (-6, -2), (-6, -8), (-1, -8)

Answers

Answer:

a) The perimeter of the rectangle =

= 22 units

b) The area of the rectangle

= 30 square units

Step-by-step explanation:

We solve the above question using the formula

= √(x2 - x1)² + (y2 - y1)²

When we are given vertices (x1, y1) and (x2, y2)

The vertices: (-1, -2), (-6, -2), (-6, -8), (-1, -8)

We have to find the length of the sides

Side A

(-1, -2), (-6, -2)

= √(-6 - (-1))² +( -2 -(-2))²

= √-5² + 0²

= √25

= 5 units

Side B

(-6, -2), (-6, -8)

= √(-6 - (-6))² + (-8 - (-2))²

= √(-6 +6)² + (-8 +2)²

= √0² + -6²

= √36

= 6 units

Side C

(-6, -8), (-1, -8)

= √(-1 - (-6))² +(-8 - (-8))²

= √(-1 + 6)² + (-8 + 8)²

=√ 5² + 0²

= √25

= 5 units

Side D

(-1, -2), (-1, -8)

= √(-1 -(-1))² + (-8 - (-2))²

= √(-1 + 1)² + ( -8 + 2)²

= √0 + -6²

= √0 + 36

= √36

= 6 units

From the above calculation,

Side A = Side C = 5 units

Side B = Side D = 6 units

Hence, this polygon is a quadrilateral called the RECTANGLE.

Therefore:

a) The perimeter of the rectangle =

2L + 2W

= 2(5) + 2(6)

= 10 units + 12 units

= 22 units

b) The area of the rectangle

= Length × Width

= 5 units × 6 units

= 30 square units
