Answer:

1.25

Step-by-step explanation:

Take out 1 and you get 0 and 50. the middle of 0 and 50 is 25. So, 1.25

Answer:

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex]

Step-by-step explanation:

Using the 45- 45- 90 triangle with legs 1, 1 and hypotenuse [tex]\sqrt{2}[/tex] , then

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] if the denominator is rationalised

Answer:

x=216°

Step-by-step explanation:

100%=360°

To find 10% divide by 10

10%=36°

x4

40%=144°

in a full circle thered 360°

360-144=216°

x=216°

Answer:

Ristretto will be 230 capsules i think

Step-by-step explanation:

50 customers = 50 capsules

500 capsules = 500 customers

50 time 10 = 500

so if Ristretto is 23

23 times by 10 = 230

Answer:

6 cm

Step-by-step explanation:

Area of parallelogram = 75 sq.cm

Answer:

25 I'm pretty sure

Step-by-step explanation:

5×5=25

Answer:

25 cm

Step-by-step explanation:

If it is enlarged by the scale factor of 5, you are multiplying by 5. 5 cm is the longest side, so therefore 5 cm times 5 cm is equal to 25.

Answer:

[tex]\displaystyle t=\frac{v-v_o}{a}[/tex]

Step-by-step explanation:

Equations

It's given that the velocity (v) of an object is equal to its initial velocity (vo) plus the product of its acceleration (a) and the elapsed time (t).

The equation that expresses the above relationship is

[tex]v =v_o+at[/tex]

We must write an equation that expresses time in terms of the rest of the variables given above.

Swap the equation:

[tex]v_o+at=v[/tex]

Subtract vo:

[tex]at=v-v_o[/tex]

Divide by a:

[tex]\boxed{\displaystyle t=\frac{v-v_o}{a}}[/tex]

B. 2

Step-by-step explanation:

To solve this, we need to divide 30 by 7. 30/7=4 R2

The remainder is 2, so there are 2 books left over.

Hope his helps and have an amazing day *^____^*

Answer:

2

Step-by-step explanation:

If 1 box holds 7 books...

2 boxes hold 14 books.

3 boxes hold 21 books.

4 boxes hold 28 books.

5 boxes hold 35 books.

However, since there are only 30 books, the 5th box won't be completely filled up. This gives us the answer: If Lamont fills up each box he would have 30-28, or 2 books left over.

Hope this helps!

Answer: 2000

Step-by-step explanation:

From the information, we are informed that a population of 500 doubles in size every 80 years. Therefore, the population in 160 years will have doubled twice i.e 160/80 = 2 times

First time doubling = 500 × 2 = 1000

Second time doubling = 1000 × 2 = 2000

Answer:

Step-by-step explanation:

Let us represent:

Short pieces = x

Middle pieces = y

Long pieces = z

A three foot long deli sandwich must be split into three pieces

x + y + z = 3

The middle piece is twice as long as the shortest piece

y = 2x

The shortest piece is 8 inches shorter than the longest piece.

x = z - 8

z = x + 8

We substitute

x + y + z = 3

x + 2x + x + 8 = 3

5x = 8 - 3

5x = 5

x = 5/5

x = 1

y = 2x

y = 2 × 1

y = 2

z = x + 8

z = 1 + 8

z = 7

How long should the three pieces be?

Answer:

Madison has earned 180 dollars in all.

Step-by-step explanation:

Let [tex]x[/tex] denotes amount earned by Madison.

Percentage of amount saved by Madison [tex]=\frac{40}{100} x[/tex]

Amount saved by Madison [tex]=72[/tex] dollars

Therefore,

[tex]\frac{40}{100}x=72\\x=72(\frac{100}{40})[/tex]

[tex]=180[/tex] dollars

So,

Madison has earned 180 dollars in all.

Answer:

Answer A=48

Step-by-step explanation:

Took the test got it right.

The expression (2w - 2)³ × (8w⁶) is equivalent to :

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

Given is the expression as -

(2w - 2)³ × (8w⁶)

The given expression is -

(2w - 2)³ × (8w⁶)

{2(w - 2)}³ × (8w⁶)

8(w - 1)³ × (8w⁶)

(a+b)³ = a³ - 3a²b + 3ab² - b³

So, on expanding, we will get -

8(w³ - 1 - 3w² + 3w) x (8w⁶)

(8w³ - 8 - 24w² + 24w )(8w⁶)

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷

Therefore, the expression (2w - 2)³ × (8w⁶) is equivalent to :

64w⁹ - 64w⁶ - 192w⁸ + 192w⁷.

Answer:

23.41%

Step-by-step explanation:

Kirtim's purchase price was 3600 + 205 = 3805,

Kirtim sold the table for 4968 for a profit of 4968 - 3805 = 1163

Assuming requirement is for profit on revenue, so

P = 100 * (1163/4968) = 23.41%

x= -3, -7

Answer:

x = -7, -3

Step-by-step explanation:

Try to factor the left side of the equation.  

(x +7)(x + 3) = 0    Remember that if AB = 0, then A = 0 or B = 0 or both  A and B = 0

Therefore,  x + 7 = 0  or x + 3 = 0

                        x = -7  or x = -3
