pls show how you got the answer 56.35 divided by 7

Answers

394.45/7=56.35. First times the awnser by what you divide it by, then thats your awnser

Answer:

Honestly It would be hard to show how I got it, but I can try. The answer is 8.05.

Step-by-step explanation:

Your supposed to see how many times 7 goes into 56.35.

1. Can 7 go into 5? No. What about 56? Yes. It goes into 56 8 times. So right now you have 8.

2. Subtract that 56 by 56 and you get 0. Now carry down 3.

3. Since 7 can't go into 3, then what about 35? Yes. 7 goes into 35 5 times. Now you should have 8.05.

For an oxidation reaction, the temperature T required is warmer than 50°C. Complete the following inequality by dragging the correct symbol to the box.
< > ≤ ≥

T 50°C

Answers

Answer:

t<50.c I think if I read right

Answer:

T > 50°C

Step-by-step explanation:

The question is asking for an inequality that shows the required temperature for T. Since < means less than and > means greater than we will use >.

T > 50°C is the same as saying T is greater than 50°C which is what we are looking for.

Answers

Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Okay so the diameter is 6 inches right? And the area formula for a circle is: A=pi (they want you to use 3.14) r (radius) ^2 (squared)

A=(pi)r^2

and the area formula for a square is just sxs right? Side x side.

So 6x6=36 (that’s the area for the square)

And since we know the diameter we can figure out the are of the circle (I know it’s a half circle but just wait I’ll get to that)

Diameter is twice the radius.

So likewise the radius is half the diameter.

6/2=3

The radius is 3 inches.

So let’s plug that into the formula

A=(pi)3^2

That comes out to 113.1 inches

Since it’s half a circle we divide it by 2

That’s 56.55

So we add them.

56.55+36= 92.55 inches

Have a good summer :)

The answers is 92.55
