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

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.

Answer:

653

Step-by-step explanation:

The surface area of the larger cube is

2(10 x 7) + 2(12x7) + 2(10x12) = 140 + 168 + 240 = 548

The surface area of the smaller cube (minus the surface that is covered by the other figure)

4(8x3) + 1(3x3) = 96 + 9 = 105

105 + 548 = 653

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%.)

Answer:

45

Step-by-step explanation:

if they're both the same number and complimentary (adding up to 90) it'd be 90/2, which is 45.

The measure of each angle is 45 degrees.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If two angles are complementary, it means that they add up to 90 degrees.

Let the measure of angle A be x degrees.

Then, the measure of angle B is also x degrees since they are equal.

Now,

Angle A + Angle B

= x + x

= 2x

The sum of the two angles is equal to 90 degrees.

So,

Angle A + Angle B = 90

Substituting this into the previous equation,

2x = 90

Dividing both sides by 2.

x = 45

Therefore,

The measure of each angle is 45 degrees.

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

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.

Answer:

1/56 chance

Step-by-step explanation:

3/8 x 2/7 x 1/6 = 1/56

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

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
