Answer:

x = 7.5, y = 8.5

-----------------------------------

The two angles with the variable x form a linear pair and therefore:

16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5

Angles 16x - 18 and 12y are congruent as vertical angles:

16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5

Answer:

x = 7.5

y = 8.5

Step-by-step explanation:

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

To find x, equate the sum of the two angles with the variable x to 180° and solve:

⇒ (16x - 18)° + (10x + 3)° = 180°

⇒ 16x - 18 + 10x + 3 = 180

⇒ 26x - 15 = 180

⇒ 26x = 195

⇒ x = 7.5

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Therefore:

⇒ (16x - 18)° = 12y°

Substitute the found value of x into the equation and solve for y:

⇒ 16x - 18 = 12y

⇒ 16(7.5) - 18 = 12y

⇒ 120 - 18 = 12y

⇒ 102 = 12y

⇒ y = 8.5

Whats the surface area of this composite figure? ILL GIVE BRAINLEIEST

Whats the surface area of this composite figure? ILL GIVE BRAINLEIEST

Answers

Answer:

294 cm²

Step-by-step explanation:

Surface area of composite figure:

Surface area of top opened rectangular prism:

             l = 6 cm ;  w = 6 cm ;  h = 7 cm

     \(\sf \boxed{ \text{ surface area = 2h(l+w) + lw}}\)

                            = 2*7 *(6 + 6 ) + 6*6

                            = 2*7*12 + 36

                            = 168 + 36

                            = 204 cm²

Surface area of right triangular prism:

           In, right triangular prism, the base rectangle is not included.

   Surface area = bh + (S1 + S2)*L

         b is the base of the triangle. b= 6 cm

         h is the altitude of the triangle. h = 4cm

         S1 and S2 are the edges of the triangle.

        S1 = 4 cm ;  S2 = 7 cm

        L is the length of the prism. L = 6 cm

          Surface area = 6*4 + (4 + 7)*6

                                 = 24 + 11 *6

                                 = 24 + 66

                                 = 90 cm²

Surface area of the composite figure = 204 + 90

                                                              = 294 cm²

Which of the following conditions does NOT create a triangle?

Answer: The answer is 255 cm2

Step-by-step explanation:

So we are looking for the area of the right triangular prism. We first must start of by observing the lengths of each side. Once you have found out what is what multiply in order. First 12 x 5 = 60. Then multiply 13 x 15 which equals = 195. Finally you want to ad up the sums together to get 255 cm2.

Answer:

18.84 ft

Step-by-step explanation:

The formula for the circumference of a circle is to multiply the radius (The line that's 3 ft in this case) by 2 and then multiply by π, which the problem says to substitute 3.14 in. Since the radius of this circle is 3, we multiply 2 by 3 and then multiply that by 3.14 to find our circumference. 3 * 2 = 6 and 6 * 3.14 = 18.84. The circumference of this circle is 18.84 ft.

What is scale factor of the dilation?
Can scale factors be rationals numbers?
Please explain in the most detailed way you can.

Answers

1) How much larger or smaller the image will be depends on the scale factor in a mathematical object's dilatation (compared to the original object). When the scaling factor's absolute value exceeds 1, an expansion takes place.

2) No. scale factors can’t be rational numbers. Scaling up always involves a scale factor larger than 1. Let's put this in the formula, which makes it: 15 5 = 3, for instance, if the larger figure's dimension is 15 and the smaller one's is 5. As a result, it is clear that the scale factor is higher than 1.
