Mathematics

Answer:

A). Scale factor = \frac{1}{4}

B). Length of the unknown side = 2.75 feet

Step-by-step explanation:

Part A

Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,

Scale factor = \frac{\text{Side length of the image}}{\text{Side length of the preimage}}

                    = \frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}

                    = \frac{4}{16}

                    = \frac{1}{4}

Part B

Scale factor = \frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}

\frac{1}{4}=\frac{\text{Side length of the smaller rectangle}}{11}

Therefore, side length of the unknown side = \frac{11}{4} = 2.75 feet

Please help me please I will really appreciate
Sladkaya [172]

Answer:

Step-by-step explanation:

If we draw this triangle with Q as the vertex angle (the one at the top of the triangle) then the 2 sides are congruent and this is an iosceles triangle. Because this is an isosceles triangle, then the 2 base angles, angle R and angle S are congruent. If Q measures 114 degrees, then angles R and S together have to add up to the difference between 180 and 114:

180 - 114 = 66

Divide that in half so R = S = 33 degrees each

A reflecting pool is shaped like a right triangle, with one leg along the wall of a building. The hypotenuse is
maria [59]

Answer:

8 ft, 15 ft, 17 ft

Step-by-step explanation:

Let x feet be the length of the side along the building. If the hypotenuse is 9 feet longer than the side along the building, then the length of the hypotenuse is x+9 feet. If the third side is 7 feet longer than the side along the building, then the length of the third side is x+7 feet.

This triangle is right triangle. By the Pythagorean theorem,

x^2+(x+7)^2=(x+9)^2,\\ \\x^2+x^2 +14x+49=x^2+18x+81,\\ \\x^2-4x-32=0,\\ \\D=(-4)^2-4\cdot 1\cdot (-32)=16+128=144,\\ \\x_{1,2}=\dfrac{-(-4)\pm\sqrt{144}}{2\cdot 1}=\dfrac{4\pm12}{2}=-4,\ 8.

The length of the side cannot be negative, thus x=8 ft. Then x+7=15 ft, x+9=17 ft.

A dozen bagels for $7.80_<br>Vhs or<br>a pack off 3 bagels for $2.10 what is the answer​
AlladinOne [14]

Answer:

I think you should go with the second option

Step-by-step explanation:

Yes the 12 dozen gets you more but when you do the math you are spending $93 on them and I don’t think anyone wants to do that. And yes you are getting less in the other option but it is more cost effective.

I hope this helps!
