What is the square root of 32?

Answer:

$1.42

Step-by-step explanation:

The cost of postcard is $0.35 and the cost of large envelope is $1.42.

We have -

We can write -

14x + 5y = 12

10x + 15y = 24.80

Now, solving the equation graphically, we get -

x = 0.35

y = 1.42

Therefore, the cost of postcard is $0.35 and the cost of large envelope is $1.42.

Answer:

29 games

Step-by-step explanation:

Simply divide the amount spent by the number of games.

For January, it would be 56/4 = $4 each game

The same goes on for the following months, even March since the problem states that each game costs the same amount.

So $116/$4 = 29 games.

Vernon downloaded 29 games in March.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Month   Games Downloaded    Cost

  JAN                 14                      $56

  FEB                 23                      $92

  MAR                 __                     $116

  APR                 19                      $76

Now, In January the price for each game

=56 /15

=$4 each game

In February the price for each game

=92/23

=$4 per game

So, In March

= $116/ $4

= 29 games.

Hence, Vernon downloaded 29 games in March.

Answer:

The correct answer is D

Step-by-step explanation:

My reason for giving this answer is because this problem is written in expression form. Since there is a variable in the expression, You cannot solve X-7 without outside information on the value of X. So D would be the answer because The answer to a multiplication problem is called the product, Then the answer to a subtraction problem is a difference. Answer D says "The product of a number and a difference", Which would mean multiplication and subtraction.

Answer:

B = T / 14

Step-by-step explanation:

This scenario can be represented and solved using the following equation...

B = T / 14

In this equation, the variable B represents the total number of boxes required to ship all of the loaves of bread while the variable T represents the total number of loaves of bread. Since each box can only hold 14 loaves of bread, dividing the total by 14 would essentially give us the total number of boxes needed so that all of the loaves of bread are accounted for and placed in boxes.

Answer:

71 degrees

Step-by-step explanation:

1. We know that the angle is unknown as demonstrated by '?'

2. The 17 side is opposite of the unknown angle

3. The 18 side the hypotenuse (not in contact with the right angle)

4. Therefore sine will be used where, sine(degree) = opposite/hypotenuse

5. The equation should be sine(degree) = 17/18

6. Since we don't know the degree we bring sine to the left and has a negative power of 1

7. The equation now becomes degree = sine^-1 (17/18)

8. The answer to this is 70.811... which equals 70 degrees and 48 minutes which rounds to the nearest degree of 71

$2160

Step-by-step explanation:

(320*4)+(240*1)+(160*3)+(80*2) = 2160

Four ingredients costing $320 per kg, $240 per kg, $160 per kg and $80 per kg are mixed so that their masses are in the ratio 4:1:3:2. The average cost per kg of the mixture, would be $2160.

The average is defined as the mean value of the given data which is equal to the ratio of the sum of the data value to the total number of units present in the data.

It is given that

Four ingredients costing $320 per kg, $240 per kg, $160 per kg and $80 per kg are mixed so that their masses are in the ratio 4:1:3:2.

(320 x 4) = 1280

(240 x 1) = 240

(160 x 3) = 480

(80 x 2) = 160

The averege cost per kg of the mixture,

1280 + 240 + 480 + 160

= 2160

Answer:

Object b

Step-by-step explanation:

So you see that when you look at the graph it shows two point and you would think A is bigger because its higher. So when looking closely it look that object B is a lot farther that object A making it greater than object A because A is a lot higher but time is shorter than abject B.

This might be wrong so sorry I tried.

:)

Answer:

A

Step-by-step explanation:

You could do a calculation.

A: d/t = 10 / 2 = 5 m/s

B: d/2 = 4/3 = 1.33 m/s

A has the greater unit rate.

From point A to point C, we can see there's a wide range between 0 and -10. It's not possible for the answer to be B or D, since the point lays between -10 and 0, and those points are both beyond -10. Between A and C, the best answer would be C. -8.45, since the point is much closer to 10 that it is to the center, around where -5.8 would be.

Answer:

[tex]\displaystyle \cos(\alpha+\beta)=\frac{21}{221}[/tex]

Step-by-step explanation:

First, we can draw two right triangles to represent the given information.

Please refer to the attachment.

We will ignore the negatives for now.

The triangle on the left represents the ratio:

[tex]\displaystyle \tan(\alpha)=\frac{15}{8}[/tex]

And the triangle on the right represents the ratio:

[tex]\displaystyle \sin(\beta)=\frac{5}{13}[/tex]

And the unknown side, c and d, were determined using the Pythagorean Theorem.

We want to find:

[tex]\displaystyle \cos(\alpha+\beta), \; \pi/2<\alpha<\pi, \; \pi/2<\beta<\pi[/tex]

So, both α and β are in QII.

Using the Sum Identity, we can write our expression as:

[tex]\displaystyle\cos(\alpha+\beta) =\cos(\alpha)\cos(\beta)-\sin(\alpha)\sin(\beta)[/tex]

Now, we will use our triangles and what we know about our angles and quadrants.

Since α and β are in QII, cosine is always negative, sine is always positive, and tangent is always negative.

Now, we can use our trig ratios. Recall SohCahToa.

According to the first triangle, cos(α) is 8/17.

However, since α is in QII, cos(α) must be -8/17.

Likewise, according to the second triangle, cos(β) is 12/13.

Since β is in QII, cos(β) is -12/13.

Now, we can determine our sine ratios.

According to the first triangle, sin(α) is 15/17.

And since α is in QII, this stays positive.

And, sin(β), as given to us, is 5/13.

Therefore, we will substitute this into our equation. So:

[tex]\displaystyle \cos(\alpha+\beta)=(-\frac{8}{17})(-\frac{12}{13})-(\frac{15}{17})(\frac{5}{13})[/tex]

Evaluate:

[tex]\displaystyle \cos(\alpha+\beta)=\frac{96}{221}-\frac{75}{221}[/tex]

Hence:

[tex]\displaystyle \cos(\alpha+\beta)=\frac{21}{221}[/tex]

Answer:

55

Step-by-step explanation:

180-125= 55

Answer:

55

Step-by-step explanation:

Line DCF is 125. A straight line is 180. So, if you are missing a degree of an angle when you have another angel given to you, then just subtract 180 from the degree that was given. So it's more like this: 180 - 125 = 55.
