if each quadrilateral below is a trapezoid blind the missing measure’s

Answer:

Step-by-step explanation:

Square A:

Area = 225 square feet

side *side = 225

        Side =√225

                 [tex]=\sqrt{15*15}[/tex]

   Side of square A = 15 ft

Square B:

Area = 400 square feet

Side =√400

       = [tex]\sqrt{20*20}[/tex]

Side of square B = 20 ft

Use Pythagorean theorem for finding the side of Square C.

Side of square A is the altitude ;  side of square B is the base and side of square C will be the hypotenuse

hypotenuse² = base² + altitude²

                      = 15² + 20²

                       = 225 + 400

                       = 625

hypotenuse = [tex]\sqrt{625} =\sqrt{25*25}[/tex] = 25 ft

Area of square C = 625 square ft

In short,

Area of square C = area of square B + area of square A

                             = 400 + 225

                             = 625 square ft

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

Step-by-step explanation:

Answer:

4(B - 5) = S

Step-by-step explanation:

B = Ben

S = Sadie

We know that Sadie was 5 pounds less than Ben, with this information, we can create the expression B - 5 = S.

We are then told that after one year, Sadie's weight quadrupled (4), to find out how much Sadie weighs, we need to multiply her current age by 4, but we do not know her age yet, so use the equation we have already.

B - 5 = S

Since we are looking for her age quadrupled, we need to multiply the left side of the equation by 4.

[4(B - 5) = S]

This also fits us having to use parenthesis.

Answer:

4 plus the difference of 27 and 10

Step-by-step explanation:

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

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.

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]

The archway is a combination of a semi-circle and two rectangles. Then the area of the archway is 13.5π + 24 square units.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The archway with a semicircle top arch and two rectangular pillars. The lower supports are and the area of the two supports is square meters.

The upper arch can be decomposed as one semicircle with radius meters minus a semicircle with a radius of 3 meters.

The archway is a combination of a semi-circle and two rectangles.

Area of archway = 2 × Area of rectangle + Area of a semicircle

Area of semicircle will be

[tex]\rm Area\ of\ semicircle = \dfrac{1}{2} \pi (r_2^2-r_1^2)\\\\Area\ of\ semicircle = \dfrac{1}{2} \pi (6^2 - 3^2)\\\\Area\ of\ semicircle = \dfrac{1}{2} \pi (36-9)\\\\Area\ of\ semicircle =\dfrac{1}{2}* 27 \ \pi \\\\Area\ of\ semicircle = 13.5 \ \pi[/tex]

The area of the rectangle will be

[tex]\rm Area\ of\ rectangle = Length * Width \\\\Area\ of\ rectangle = 3*4\\\\Area\ of\ rectangle = 12[/tex]

Then the area of the archway will be

Area of archway = 2 × 12 + 13.5π

Area of archway = 13.5π + 24

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

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.

The sum of the angles of the triangle is 180 degrees, so:

(x + 70) + 76 + 41 = 180

(x + 70) + 117 = 180

x + 70 = 63

x = -7
