Answers

Answer 1

Answer:

A) Dilation's of an angle must be congruent to the original angle.

B) Dilation's if a triangle must be congruent to the original triangle.

Step-by-step explanation:

Dilation is one of rigid transformations in which the size of an angle or object is either increased or decreased, to produce an image, with respect to a given factor. In this process, the dimensions of the object are affected but its orientation remains the same.

When a figure is dilated, the new figure is congruent to the original figure. Also, when an angle undergoes dilation, its measure is not affected. Thus, it would be congruent to the original angle.

Answers

Answer:

I hope it will help u , please Brain -list the question

Step-by-step explanation:

As given that

L:W=5:4

L/W=5/4

L=(5/4)W

hence we also know that

Area of rectangle= L*W

As given A=160m2

putt the value of A and L=(5/4)W in above equation ,

hence 160 = (5/4)W * W

W^2 = 160*4/5

W^2 = 32*4

W^2=128

taking square root

W= +_ 11.3

but length can't be negative so we take positive value of W

W=11.3 m

Now for L putt in above equation,

L=5/4 * 11.3 = 14.12 m

i need a step by step explanation

Answers

Step-by-step explanation:

3(1-9a)+22a=2(2a-9)-15

3-27a+22a=4a-18-15

-27a+22a-4a=-18-15-3

-a=-36

a=36

Answer:

A= 4

Step-by-step explanation:

3(1-9a)+22a=2(2a-9)-15

3-27a+22a=2(2a-9)-15

3-5a=2(2a-9)-15

3-5a=4a-33

3-5a-3=4a-33-3

-5a=4a-36

-5a-4a=4a-36-4a

-9a=-36

-9a/-9 = -36/-9

870 g of brass contains 40 percent zinic and the rest is copper.find the mass of zinic and copper in the alloy

Answers

Step-by-step explanation:

Mass of Zinc = 870g * (40/100) = 348g.

Mass of Copper = 870g - 348g = 522g.

Mass of zinc = 40/100*870 = 348

Mass of Copper = 60/100*870 = 522

Therefore, the mass of zinic in the alloy is 348 and the mass of copper in the alloy is 522.

Three guys rent a hotel room for the night. When they get to the hotel they pay the $30 fee, then go up to their room. Soon the bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep one of the $5 dollars and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend they could not explain the following details:

Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip. HOWEVER, 3 • $9 + $2 = $29.

The guys couldn't figure out what happened to the other dollar. After all, the three paid out $30 but could only account for $29.
