12. 21.35 - 8.95 = 12.4

cost of colored pencils = $12.40

13. 37- 8 = 29

14. $95  - $73 = $22

Answer:

b. option Is the correct answer

Answer:

Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.

Answer:

n[total]=25

n[top finishers]=8

the number of possible outcome

=[tex] \frac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18}{8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1} = 1081575[/tex]outcomes

Answer:

[tex] \large\boxed{ \boxed{\rm 1081575 \: outcomes}}[/tex]

Step-by-step explanation:

to determine the number of possible outcomes we can consider Combination given by

[tex] \displaystyle \binom{n}{r} = \frac{n!}{r!(n - r)!} [/tex]

where:

so let n and r be 25 and 8 respectively thus

substitute:

[tex] \displaystyle \binom{25}{8} = \frac{25!}{8!(25- 8)!} [/tex]

simplify parentheses:

[tex] \displaystyle \binom{25}{8} = \frac{25!}{8! \times 17!} [/tex]

rewrite numeratorr:

[tex] \rm \displaystyle \binom{25}{8} = \frac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18 \times 17!}{8! \times 17!} [/tex]

reduce fraction:

[tex]\rm \displaystyle \binom{25}{8} = \frac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18 }{8! } [/tex]

simplify numerator and denominator:

[tex]\rm \displaystyle \binom{25}{8} = \frac{43609104000}{40320 } [/tex]

simplify division:

[tex]\rm \displaystyle \binom{25}{8} = 1081575[/tex]

hence,

the number of outcomes is 1081575

Answer:

48pq².

Step-by-step explanation:

(4pq+3q)² - (4pq - 3q)²​

This is the difference of 2 squares so we can use the identity

a^2 - b^2 = (a - b)(a + b):

(4pq+3q)² - (4pq - 3q)²​

= (4pq + 3q - (4pq - 3q)(4pq + 3q + (4pq - 3q)

= (4pq + 3q - 4pq + 3q)(4pq + 3q + 4pq - 3q)

= 6q * 8pq

= 48pq².

Answer:

48pq²

Step-by-step explanation:

As we know,

(a + b)² = a² + 2ab + b²

and

(a – b)² = a² – 2ab + b²

So,

(4pq+3q)² - (4pq - 3q)²​

= [(4pq)² + 2 X 4pq² X 3q + (3q)²] – [(4pq)² -  2 X 4pq² X 3q + (3q)²]

= (16p²q² + 24pq²+ 9q²) – (16p²q² – 24pq²+ 9q²)

= 16p²q²+ 24pq²+ 9q² – 16p²q²+ 24pq² – 9q²

= 24pq² + 24pq²

= 48pq²

Answer:

the diameter of Britain flag is given = 28mm

so the radius = 14mm

perimeter of the flag occupied = 2πr = (2×22/7×14) mm

= 88mm

area of the flag= πr^2 = (22/7 × 196) mm^2 = 616 mm^2

Answer:

The equation for the speed of the train is: 162 = 3x

I think the speed of the train is 54 miles per hour

Step-by-step explanation:

We know that:

y = distance in miles

x = speed of train (miles/hour)

t = time traveled from the departing station (hours)

The equation: y = xt is given, we can therefore substitute the give values:

y = xt or tx

162 = 3x (This would be the equation)

Now we can find x by diving 3 on both sides of "="

162/3 = x

54 = x (This would be the speed of train)

Hope this helps!

Answer:

(9-57i)

Step-by-step explanation:

We need to find the product of the given complex number i.e.

(3-9i)(6-i)

It can be solved as follows :

(3-9i)(6-i) = 3(6) +3(-i) +(-9i)(6) + 9i(i)

= 18-3i-54i+9i²

We know that, i² = -1

So,

= 18-3i-54i+9(-1)

= 18-57i-9

= 9-57i

So, the product of the given complex number is (9-57i).

Answer:

[tex]2\frac{1}{3}^{2}[/tex] or 49/9 inches squared

Step-by-step explanation:

you have a square if those lengths are correct, and the formula for the area of a square is Bh=A B=base length (side on bottom), h=height (vertical side), and A=area, so 2 1/3 * 2 1/3 or 2 1/3^2

if that doesnt make sense, message me and i will try to help you more

Answer:

2028 square inches

Step-by-step explanation:

The side length of the styrofoam cube measures 6 1/2 inches.

Step 1

We find the surface area of a cube

The formula is given as

Surface Area = 6a²

Where a = Side length of the cube = 6 1/2 inches

Hence,

Surface area of a cube = 6 × (6 1/2inches)²

= 253.5 square inches

Step 2

Huy is painting eight styrofoam cubes for a science project.

The total surface area that Huy will paint is calculated as:

1 styrofoam cube = 253.5 square inches

8 styrofoam cubes = x

Cross Mulitiply

x = 8 × 253.5 square inches

x = 2028 square inches

Therefore, the total surface area that Huy will paint is 2028 square inches.

Answer:

5 apples cost = 150 /-

Step-by-step explanation:

Two apples cost = 60 /-

Then 1 apple cost = 60 ÷ 2

= 30

∴ 1 apple cost = 30 /-

Then 5 apples cost = 30 × 5

= 150

∴ 5 apples cost = 150 /-
