Answers

Answer 1

Answer:

[tex]Sin ~0 =\frac{2\sqrt{5} }{5}[/tex]

Step-by-step explanation:

[tex]sec0=\sqrt{5}[/tex]

[tex]cos~0=\frac{1}{sec0} =\frac{1}{\sqrt{5} }[/tex]

[tex]sin ~0=\sqrt{1-cos^2~0}[/tex]

[tex]=\sqrt{1-1/5}=\sqrt{5-1/5}[/tex]

[tex]Sin~0=\sqrt{4/5} =2/\sqrt{5}*\sqrt{5}/\sqrt{5}[/tex]

[tex]Sin~0=2\sqrt{5}/2=2\sqrt{5}/5[/tex]

By selling a watch on 400 and 460’. Loss and profit happened respectively.if the loss and profit are equal, find cp.

Answers

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be xProfit and Lost be y .

According to the Question :-

[tex]:\implies[/tex] 460 = x + y ( Profit)

[tex]:\implies[/tex] 400 = x - y ( Loss)

Adding both :-

[tex]:\implies[/tex] 460 + 400 = x + y + x - y

[tex]:\implies[/tex] 860 = 2x

[tex]:\implies[/tex] x = 860/2

[tex]:\implies[/tex] x = 430

Hence the Cost price of the watch is 430 .

Answer:

  7 square inches

Step-by-step explanation:

We take the "3 in" dimension at the left to be the length of the line segment below the 1" square, so the height of the right triangle is 3+1 = 4 in.

The triangle area is ...

  A = 1/2bh

  A = 1/2(3 in)(4 in) = 6 in²

The square area is ...

  A = s²

  A = (1 in)² = 1 in²

Then the total area of the figure is ...

  1 in² + 6 in² = 7 in²

Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in, high. Her paper is 12 in, wide and 24 in. tall. She decides to use the scale 1 in. = 4
in. Is this a reasonable scale?

Answers

Step-by-step explanation:

1:4=.25 or 25%

so 12/47=.25 or 25%

24/120=.2 or 20%

that ratio does not match the height ratio

Sarah's scale is reasonable.

What is a scale drawing?

A scale drawing is a smaller diagram in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.

Is Sarah's scale reasonable?

The first step is to determine the how larger the paper is in terms of the painting.

48 / 12 = 4

120 / 24 = 5

This makes her scale of 1 in to 4 in reasonable.

Answer:

78.5 cm^2

Step-by-step explanation:

the circle's diameter is 10cm --> its radius is 5cm

the area of the circle is 5^2 x 3.14 = 78.5cm^2

The area of circle is [tex]25\pi[/tex] square units.

What is the formula for area of circle?

The area of a circle is given by [tex]\pi r^{2}[/tex] where r is the radius of the circle.

What is the area of given circle?

The given circle is inscribed in a square. so, the side length of the square will be the diameter d of the circle.

So, d=10.

Divide diameter d by 2 to get the radius of the circle.

[tex]r=\frac{10}{2}[/tex]

So, r=5.

Substitute 5 for r into the formula of area of circle.

[tex]\pi \cdot5^{2}=25 \pi[/tex]

Therefore, the area of circle is [tex]25\pi[/tex] square units.

13. A bag contains 8 red marbles, 4 purple marbles, 5 green marbles, 2 orange, and 1 blue
marbles. One marble is selected and replaced. A second marble is selected. Find the
probability of each compound event. Show work and simplify your solutions.
a)
Not selecting an orange marble and then a blue marble
b)
Selecting a green or red marble and then a purple marble

Answers

Answer:

a) 9 / 200

b) 13 / 100

Step-by-step explanation:

a) The two events are independent because they do not depend each other since the marbles are replaced. To find the total probability of two independent events, you multiply the probability of each event together.

Probability is represented by the amount of desirable outcomes over the total number of outcomes. The total would be the number of marbles, which is: 8 + 4 + 5 + 2 + 1 = 20 outcomes. The number of orange marbles is 2, so the outcomes where you do not pick orange are 20 - 2 or 18 outcomes. The probability of not picking an orange marble would be 18 / 20 or 9 / 10 (using the formula for probability).

There is one outcome where we can pick a blue marble, so the probability of picking a blue marble is 1 / 20. Now, we need to multiply the probabilities for each event: 1 / 20 * 9 / 10  = 9 / 200

b)There are 5 green marbles and 8 red marbles, so the the total outcomes where you pick green or red is 13. We put that over our total to get 13 / 20.

There are 4 purple marbles, so the probability of picking purple is 4 / 20 or 1 / 5. Now we multiply the two probabilities to get the total probability: 1 / 5 * 13 / 20 = 13 / 100

Create an equation to represent the total number of pens and pencils,
p
, Alex has.

Answers

Answer:

a. p = n + m

where: n is the number of pens, and m is the number of pencils

b. p = 71

Step-by-step explanation:

Let the number of pens  and pencils that Alex has be represented by n and m respectively.

But,

number of pens, n = 14

number of pencils, m = 57

Then,

total number of pens and pencils, p = number of pens + number of pencils

i.e p = n + m

p = 14 + 57

p = 71

The total number of pens and pencils that Alex has is 71.

Astronomers have estimated that our cosmos contains approximately 50,000,000,000 galaxies. This number can be expressed in scientific notation as
1. 5E-10
2. 5E10
3. 5E-9
4. 5E9

Answers

Answer:

Second option: 5E 10 = 5*10^(10) galaxies.

Step-by-step explanation:

The exponential notation is used as:

AE N

This is equal to:

A*10^(N)

And we need to add N zeros to the right of A.

While if we had:

AE - N

A*10^(-N)

We need to add N - 1 zeros at the left of A.

Now we have the number:

50,000,000,000

Let's count the number of zeros at the right of the 5, we have 10 zeros.

Then we would write this as:

5*10^(10)

OR

5E 10

Then the correct option is the second one.
