Serena makes 2 1/4 cups of popcorn using 1 1/2 tablespoons of kernels. She wants to know how many tablespoons of kernels to use to make 6 cups of popcorn
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.

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

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
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.

What number should go in the box? 343834=300000+▢+3000+800+30+4
Answers
Answer:
40 000
Step-by-step explanation:
Find out what the numbers in the equation add up to excluding the box.
343834 - 300000 - 3000 - 800 - 30 - 4 = 40 000
Answer:
40000
Step-by-step explanation:
300000+3000+800+30+4 = 303834
So,
343834-303834 = 40000

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)

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

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

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%.)
