(2 tens 1 one)x10 in unit form and standard form
omeli [17]

When the number expression given as (2tens 1 one) x 10 is written in standard form, the standard form is 210 and the unit form is 2 hundred, and 1 ten

<h3>How to write the number in standard form?</h3>

The number expression is given as:

(2tens 1 one) x 10

2 tens is represented as:

2 * 10

1 one is represented as:

1 * 1

So, the number expression can be rewritten as:

(2tens 1 one) x 10 = (2 * 10 + 1 * 1) x 10

Evaluate the product

(2tens 1 one) x 10 = (20 + 1) x 10

Evaluate the sum

(2tens 1 one) x 10 = (21) x 10

Evaluate the product

(2tens 1 one) x 10 = 210

When the number expression given as (2tens 1 one) x 10 is written in standard form, the standard form is 210 and the unit form is 2 hundred, and 1 ten

Using the above steps as a guide, we have:

  • (5 hundreds 5 tens) * 10 ⇒ 5 thousands and 5 hundreds ⇒ 5500
  • (2 thousands 7 tens) / 10 ⇒ 2 hundreds and 7 units ⇒ 207
  • (4 ten thousands 8 hundred) / 10 ⇒ 4 thousands and 8 tens ⇒ 4080

If anyone can help that would be great thanks and of you can plz show the work
worty [1.4K]

Answer:

Question 1:  0.38, 3/8, 25%

Question 2: 72oz.

Question 3: 165

Step-by-step explanation:

First Question: We can make all the numbers to decimals. 25%= 0.25, 3/8= 0.375, and 0.38 is given. Then we can clearly see that 0.38, 3/8, 25% is the order.

Second Question: There are 16oz. in a pound, so we have to multiply 4.5 and 16. 4.5*16 = 72. There are 72 oz. in 4.5lbs.

Third Question: We just have to plug 5 in, so 7(5)^2 - 10 is our equation. Following the order of equations, we have the exponent first. 5^2 is 25. We end up with 7(25) - 10. Then we have to multiply, so 7*25 = 175. Finally we have 175 - 10 which is 165.
