Answer:

2.23 \times 10^{5}

Step-by-step explanation:

We have to find the sum of two numbers following the steps as described in the question.

The question is in the form of fill in the blanks.

Now, the given sum is (3.3 \times 10^{4} )+(1.9 \times 10^{5} )

= (3.3 \times 10^{4} )+(19 \times 10^{4} )

= (3.3+19) \times 10^{4}

= 22.3 \times 10^{4}

= 2.23 \times 10^{5} (Answer)

What is the volume of a cylinder with base radius 4 and height 5?
Vsevolod [243]

Answer:

251.2 unit²

Step-by-step explanation:

Radius = 4 unit,  height = 5 unit

Volume of cylinder = pi r² h

Where pi(#) = 3.14

Volume = # × 4² × 5

Volume = # × 16 × 5

Volume = 80# unit²

Volume = 80 × 3.14

Volume = 251.2 unit²

Rearranging equations<br>​
tatyana61 [14]

Answer:Rearrange the equation so that the unknown variable is by itself on one side of the equals sign (=) and all the other variables are on the other side. RULE #1: you can add, subtract, multiply and divide by anything, as long as you do the same thing to both sides of the equals sign.

What is the length of HG?
Leviafan [203]

Answer:

HG = 5

Step-by-step explanation:

Given

HE = 8mm

EF = 12mm

Area = 68mm^2

Find the length of HG

First, it should be noted that the displayed figure is a trapezium

<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>

In this case;

Area = \frac{HG + EF}{2} * HE

Substitute the values of Area, HE and EF

68 = \frac{HG + 12}{2} * 8

68 = (HG + 12) * 4

Divide both sides by 4

\frac{68}{4} = \frac{(HG + 12) * 4}{4}

17 = HG + 12

Subtract 12 from both sides

17 - 12 = HG + 12 - 12

5 = HG

HG = 5

<em>Hence, the length of HG is 5mm</em>

What greater 1/2 or 1/12
laila [671]

Answer: 1/2

Step-by-step explanation: To find out what fraction is greater, notice that the fractions that we're comparing in this problem have different denominators.

When fractions have different denominators, they're called unlike fractions.

To compare unlike fractions, we must first get a common denominator. The common denominator of 2 and 12 will be the least common multiple of 2 and 12 which is 12.

To get a 12 in the denominator of 1/2, we multiply the numerator and the denominator by 6 which gives us 6/12.

Notice that 1/12 already has a 12 in the denominator so now we are comparing like fractions since both of them has a 12 in the denominator.

To compare like fractions, we simply look at the numerators. Since 6 is greater than 1, this means that 6/12 is greater than 1/12.

Therefore, 1/2 is greater than 1/12.
