Answer:

x = 5 and y = 14

Step-by-step explanation:

Given \triangleABC\cong \triangleDEF.

Congruent triangles have congruent corresponding parts, so

AB\cong DE\\ \\AC\cong DF\\ \\BC\cong EF

Since

AB=8\\ \\BC=19\\ \\AC=14\\ \\EF=4x-1\\ \\DE=y-6,

then

4x-1=19\\ \\4x=19+1\\ \\4x=20\\ \\x=5

and

y-6=8\\ \\y=8+6\\ \\y=14

Answer:

1. A container of milk 2L

2. An Eyedropper has 1 mL

3. A cup of punch 250 mL

4. A jar of pickles 500mL

Step-by-step explanation:

Without even measuring, just think of this problem logically. Remember that a 1 L is 1000mL, so it is 1000 times more than 1 mL.

A milk container would hold more than a cup of milk and that is more than 20 mL. The most logical answer would be 2L.

An eyedropper can hold just a little amount of liquid. Just think that it dispenses liquid in drops, the best answer would be 1mL (which is actually an estimate of the volume of a drop is.)

A cup of punch is about 250 mL. The keyword there is a CUP and 25L is a big amount and the cup would have to be HUGE.

Same as above, the keyword there is a jar. A 50L jar would be a very big amount for just a jar of pickles.

Answer: 96 ft²

Step-by-step explanation:

<u>This figure can be divided into two rectangles:</u>

  • The first rectangle has dimensions 6 ft by 14 ft.
  • The second rectangle had dimensions 4 ft by 3 ft.

<u />

<u>Find the area of both rectangles:</u>

  • The first rectangle: 6 × 14 = 84 ft²
  • The second rectangle: 4 × 3 = 12 ft²

<u />

<u>Add them together to find the total area of the figure:</u>

84 + 12 = 96 ft²

Find the circumference and area
kozerog [31]
C=2pi(r)

Pi=3.14

r=5.5

So C=2(3.14)(5.5)=34.56

So the circumference is 34.56 mi

And the area is A=pi(r)²

So you have

A=3.14(5.5)²

So A=95.03 mi²


So the area is 95.03 mi² and the circumference is 34.56 mi


Hope this helps!
