Answer:

60 servings

Step-by-step explanation:

Method 1: 2.5/10 (fraction) = 15/x (fraction)

Draw an arrow from 2.5 to 15 and write x6 (times 6)

Do the same from 10 to x

Then do 10*6 = 60

I don't know another method but hope this helps!

Step-by-step explanation:

First method :-

Using unitary method,

5/2 scoops = 10 servings

1 scoop = 10/5/2 = 4 servings

15 scoops = 15 * 4 = 60 servings

15 scoops = 60 servings of bannock

Second method :-

Using proportions,

Let x be servings of bannock for 15 scoops

Let ratios be 5/2 : 10 and 15 : x

Now,

5/2 : 10 = 15 : x

or, 5/2/10 = 15/x

or, 5/2 * 1/10 = 15/x

or, 1/4 = 15/x

or, x = 15 * 4

so, x = 60

So,

15 scoops = 60 servings of bannock

x = 8

The part that needs revision in the construction of the tangent to the triangle is C. Vance should have constructed all three altitudes instead of only constructing two altitudes.

A triangle simply means a polygon that has three sides. Also, a triangle has there's edges as well as vertices.

In this case, in order to construct a circle tangent to all three sides of the acute, scalene triangle LMN, it should be noted that the three altitudes have to be taken into consideration.

This wasn't the case in the step given by Vance as only two altitudes were considered. Therefore, this should be the change that is required.

Answer:

16/49

Step-by-step explanation:

First we apply the fraction rule a/b ÷ c/d = a/b × d/c :

2/7 ÷ 7/8

2/7 ×8/7

Multiply fractions using this rule a/b × c/d = a×c/b×d :

2×8 =16

7×7=49

So our final answer is 16/49

The derivative of  cosec x² is [tex]-2x.cot \ x^{2} .cosec \ x^{2}[/tex]

From the question, we are to differentiate cosec x²

Let y = cosec x², then we will determine the value of [tex]\frac{dy}{dx}[/tex]

[tex]y = cosec \ x^{2}[/tex]

Let [tex]u = x^{2}[/tex]

Then,

[tex]\frac{du}{dx}=2x[/tex]

Also, [tex]y = cosec \ x^{2}[/tex]  becomes

[tex]y = cosec \ u[/tex]

Then,

[tex]\frac{dy}{du} = - cot \ u . cosec \ u[/tex]

From Chain rule

[tex]\frac{dy}{dx} = \frac{dy}{du}\times \frac{du}{dx}[/tex]

∴ [tex]\frac{dy}{dx} = -cot \ u.cosec \ u \times 2x[/tex]

Recall that [tex]u = x^{2}[/tex]

Then,

[tex]\frac{dy}{dx} = -cot \ x^{2} .cosec \ x^{2} \times 2x[/tex]

[tex]\frac{dy}{dx} = -2x.cot \ x^{2} .cosec \ x^{2}[/tex]

Hence, the derivative of  cosec x² is [tex]-2x.cot \ x^{2} .cosec \ x^{2}[/tex]

Answer:

(n-2) x 180 degrees

Step-by-step explanation:

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180° where n is the number of sides. All the interior angles in a regular polygon are equal.

Answer:

19 = y

Step-by-step explanation:

Hello!

These angles are vertical angles or angles that are formed by two lines that intersect. The two non-adjacent angles that are formed are congruent and known as Vertical Angles.

Now that we know what vertical angles are, we know that these two angles (19° and y) are congruent because they are formed by the intersection of two lines and are non-adjacent.

19 = y is your answer

So yes the area of a circle is a function of its radius

Answer:  Area is a function of the radius, but radius is not a function of the area

Since the area of a circle is A = PI^2 , the value of the area depends on the radius, so area is a function of the radius, but not the other way around.

Answer:

C

Step-by-step explanation:

The answer is C because it is the only one where any combination of 2 sides will add up to be greater than the other sides.

Answer:

Step-by-step explanation:

A is not possible, because 5 + 4 < 10 (doesn't satisfly inequality.)
B is also not possible => 5 + 7 < 13 (doesn't satisfy inequality.)
D is also not possible => 4 + 5 < 10 (doesn't satisfy inequality)

So, the answer is C, cause the sum of 2 sides is always more than the other one.

By looking at the graph, we can see that the minimum is y = -6.

The minimum of a function is the smallest value that f(x) takes, to see it, we need to find the lowest value of f(x) in the graph.

In this case, the minimum would be the value that the function takes in the troughs, which we can see is equal to -6.

Then we can conclude that the minimum of the function is y = -6
