Answer:

The angle of CAD is 100°.

Step-by-step explanation:

Given that total angles in a triangle is 180° so you will have to find the angle of CAB :

∠CAB + ∠ACB + ∠ABC = 180°

∠CAB + 80° + 20° = 180°

∠CAB + 100° = 180°

∠CAB = 180° - 100°

∠CAB = 80°

Next, you have to subtract it from 180° because straight line have a degree of 180°

∠CAD = 180° - 80°

∠CAD = 100°

What is 168.023 in expanded form using fractions

bonufazy [111]

Answer:

The expanded form of 168.023 is 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$

Step-by-step explanation:

Expanded form:

Is a way to write numbers to see the math value of the digits.

When numbers are separated into their place values and decimal places they can also form a mathematical expression.

Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 + $\frac{2}{10}$ + $\frac{7}{100}$ = 5,325.27

Let us solve the question

∵ The number is 168.023

∵ Its hundreds digit is 1

∴ Its value = 100

∵ Its tens digit is 6

∴ Its value = 60

∵ Its units digit is 8

∴ Its value = 8

∵ Its tenths digit is 0

∴ Its value = 0

∵ Its hundredths digit is 2

∴ Its value = $\frac{2}{100}$

∵ Its thousandths digit is 3

∴ Its value = $\frac{3}{1000}$

∴ The expanded form of 168.023 = 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$

Two more than the product of a number and 8 is 5

Andreyy89

When ever the problem says is, the next number after that is going to be the answer to the equation. So now you have =5.

Next it say two more which means adding so now we have, +2=5

Now we have the product of a number and 8. This means that the number and 8 equal the product. Now we know that an answer that is a product is a multiplication problem. That means that you have to multiply 8 and the number.

That leaves us with the answer, n•8+2=5
