Explanation:

First lets do the long division method. First we need to fit 5 into 5. That would be 1. So we write a 1 above the 546. Then we need to fit 5 into 4. Well it doesn't fit so we write a zero move another number. How many 5s fit into 46 well that would be 9. All we have left is a remainder of 1 which cannot fit into 5 and there are no more numbers

Answer:

If you want a decimal that would be 109.2 or 109 1/5

Answer:

109.2

Step-by-step explanation:

If the number being divided does not end in 5 or 0, it being divided by 5 will not be equal. Therefor it might be better to try and use a calculator if you can't do it in your head.

You’re given three angle measurements of 30°, 70°, and 80°. how many triangles can you construct using these measurements?

Papessa [141]

You can only make one triangle because every triangle has 180 degrees so if you add these you get exactly 180 degrees for one triangle

Bess [88]

Answer:

12566.4 mm²

Step-by-step explanation:

The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.

TSA = Total Surface Area

CSA = Curved Surface Area

TSA of open cylinder = CSA of cylinder + area of base or top

= 2πrh + πr²

= πr(2h + r)

From the above question:

r = 50mm

h = 15mm

Hence,

= π × 50 (2 × 15 + 50)

= π × 50 (30 + 50)

= π × 50(80)

= π × 4000

= 12566.370614mm²

Approximately = 12566.4 mm²

The Surface Area of the petri dish with no lid = 12566.4 mm²

Bluprints of a house are drawn to the scale of 1/4=1 foot .On the bluprints, one of the kitchen wallsis 3.5in. What is the actua

max2010maxim [7]

Answer:

The actual size of the kitchen is <u>1.17 feet</u>.

Step-by-step explanation:

Given:

Blueprints of a house are drawn to the scale of 1/4=1 foot .On the blueprints, one of the kitchen walls is 3.5 in.

Now, to find the actual size of the kitchen.

Let the actual size be $x.$

On the blueprints, one of the kitchen walls is 3.5 in.

Blueprints of a house are drawn to the scale of 1/4=1 foot.

1 foot = 12 in.

$\frac{1}{4}=\frac{1}{4} \times 12=3\ in.$

So, 3 in is equivalent to 1 foot.

Thus, 3.5 in is equivalent to $x.$

Now, to get the actual size by using cross multiplication method:

$\frac{3}{1} =\frac{3.5}{x}$

<em>By cross multiplying we get:</em>

$3x=3.5$

<em>Dividing both sides by 3 we get:</em>

$x=1.17\ feet.$

Therefore, the actual size of the kitchen is 1.17 feet.
