Answer:

53 sweets.

Step-by-step explanation:

The mean out of 10 bags of sweets is 42. That means that all the numbers of sweets added up would be 420.

39 + 40(2) + 41(5) + 43 + x = 420

39 + 80 + 205 + 43 + x = 420

367 + x = 420

x = 53.

So, in the 10th bag, there are 53 sweets and a sugar high for whoever eats that many sweets.

Hope this helps!

C is yo answer of y=3x-1

Step-by-step explanation:

the y intercept is -1 and yo slope is 3. you could see yo line goin up by three and to tha right by 1

Answer:

Step-by-step explanation:

an equation perpendicular to the equation given will have a slope of -1, because a perpendicular slope is opposite and reciprical. if it goes through the point 4,-1 and has a slope of -1, the y intercept has to be 3. y = -x + 3

parallel lines have to have the same slope of 3.

Answer: 216 millilitres

Step-by-step explanation:

From the question, you are given that there are 3 milliliters of compound A used for every 5 milliliters of compound B. That means compound A and B are in ratio 3 to 5. That is,

A : B = 3 : 5

If a chemist wants to make 576 milliliters of the drug, then find the ratio of compound A.

To do that, first add the ratio of both together, 3 + 5 = 8

For compound A,

3/8 × 576

1728/8 = 216 millilitres

Therefore, 216 millilitres of compound A are needed.

Answer:

f(1) = -11

f(n) = f(n-1) +3  n=2,3,4,5

Step-by-step explanation:

-11,-8,-5,-2,1,....

We are adding 3 each time

-11 +3 = -8

-8+3 = -5

f(1) = -11

Take the previous term and add 3

f(n) = f(n-1) +3  n=2,3,4,5

Answer:

273.7

Step-by-step explanation:

first fine the sides that isn't the base.

triangle area formula: (b*h)/2

(14*9)/2 = 63

since there are 3 sides you multiply this by three.

63*3=189

then find the base.

same formula since its a triangle.

(12.1*14)/2 = 84.7

now add them both up:

84.7+189 = 273.7

Step-by-step explanation:

One solution would be (1, -4), and the other would be (4, -7).

The ordered pairs which are the solutions of the system of equations shown in the graph below are (1,-4) and (4,-7).

The ordered pair is the pair of two numbers which represented in a manner that it provides a particular order.

In a order pair the first term indicates the x-coordinate, while the second term indicate the y-coordinates. The ordered pair are written in close bracket in the following way.

Answer:

I guess that the expression is:

(y^2*y^3)/(y*y^(-2))

remember this two relationships.

a^x*a^y = a^(x + y)

(a^x)/(a^y) = a^(x - y).

then we have:

y^2*y^3 = y(2 + 3) = y^5.

and

y*y^(-2) = y^(1 + (-2)) = y^-1

then our expression can be written as:

(y^2*y^3)/(y*y^(-2)) = y^5/y^(-1) = y^(5 - 1) = y^4.

Then the correct option is b: y^4

Answer:

40°

Step-by-step explanation:

The triangle is a right triangle, so one measure of one of the angles is 90 degrees.

One acute angle measures 50 degrees.

Angles in a triangle add up to 180 degrees.

180 - 90 - 50

⇒ 40

The measure of the other acute angle is 40 degrees.

Acute angles measure less than 90 degrees. 40 degrees is less than 90 degrees, so it is an acute angle.

The measure of the other acute angle is 40°.

Given that, in a right triangle, one acute angle measures 50°.

A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.

Let the measure of other acute angle be x.

Using angle sum property of a triangle, we get

90°+50°+x=180°

⇒ x=180-140

⇒ x=40°

Therefore, the measure of the other acute angle is 40°.

Answer:

Step-by-step explanation:

Suppose that the side length is s.  Imagine that one side is level.  Draw a vertical line through the top vertex perpendicular to the base (level side).  Label this vertical line "h."  Then h and s are related as follows:

                               √3          h

sin 60 degrees = ------- = --------

                                 2           s

                                                                   s√3

and so h = the height of the triangle =  -----------

                                                                       2

The area of this triangle is (1/2)(base)(height), which here is:

Step-by-step explanation:

Notice that  4 times 84 is 336, so in 84 pages he can get 336 photographs, there are just 2 left to complete the 338 he had. So the last page gets 2 photos.

Answer & Step-by-step explanation:

For this problem, we will be using the tangent trig ratio because we are dealing with the opposite side and the adjacent side of the triangle. Although cosine may be a good ratio to use as well, it is not the best ratio to use because if you were to use the cosine ratio, you will have more steps to complete in order to solve the problem. Plus, we are not dealing with the hypotenuse side of the triangle. Therefore, it is best to use the tangent ratio because it is more efficient and it corresponds to the side lengths we are using.

On the next page, we are given a Venn Diagram. We are asked to tell the difference between finding the angle and finding the side. Then, we are asked to find the similarity between them.

When solving for the unknown side, you have to flip the equation because one of the sides will be known as a variable.

When solving for the unknown angle, you have to use the inverse of the trig ratio that you are using for that problem.

The similarity between the two is that they will always use one of the trig ratios.
