Answer:
C
Step-by-step explanation:
It's not rational. It can't be represented as a fraction.
It can't be a decimal the ends. If I told you want the hundredth digit was, you could not establish the 101st digit.
If you try to find the square of 7 using the calculator that comes with winds, you get an answer that goes out to 2 followed by the decimal followed by 31 digits. You cannot find a pattern nor can you find an ending.
sqrt(7) is irrational.
Answer:
- Find the coefficients using ax^2 + bx + c = 0
a = 4
b = 7
c = 0
- Make the coefficient equal 1. But how do we do that? Division.
4n² + 7n = 0
4/4n² + 7n/4 = 0/4
= n² + 7/4n = 0
a = 1
b = 7/4
c = 0
- Complete the square using b/2².
b = 7/4
(b/2)² = (7/4 ÷ 2)²
Use fraction rule.
7/4 ÷ 2² = 7/4² / 2²
<em>square the numbers</em>
7/4² / 2² = 49/16 ÷ 4
49/16 ÷ 4 = 49/16 × 1/4
49/16 × 1/4 = 49/64
Add to both sides of the equation using 49/64
b = 7/4
b/2 = 7/4 ÷ 2
<em>simplify</em>
b/2 = 7 ÷ (4 × 2)
<em>simplify(arithmetic)</em>
b/2 = 7/8
n² + 7/4n + 49/64 = 49/64
(n + 7/8)² = 49/64
Next, cancel out the square on the left side.
Subtract 7/8 from both of the sides.
Simplify the left side.
<em>That wraps it up for this equation. Hope it helped!</em>
D, because tutoring and receptionist is UPTO 20 hours and the money is AT LEAST 200
Hi! here’s what i’d put for the sentences to fill in the blanks:
- 1 ten is equal to 10 ones. 1 ten is 10 times the value of 1 one.
- 1 hundred is equal to 10 tens. 1 hundred is 10 times the value of 1 ten.
- 1 thousand is equal to 10 hundreds. 1 thousand is 10 times the value of 1 hundred.
- 1 ten-thousand is equal to 10 thousands. 1 ten-thousand is 10 times the value of 1 thousand.
- 1 hundred-thousand is equal to 10 ten-thousands. 1 hundred-thousand is 10 times the value of 1 ten-thousand.

Answer:
$2,800 and $6,400
Step-by-step explanation:
Aquí, sabemos que hay un 20% de descuento en compras.
Entonces, para una persona que compró cosas por valor de $ 3,500, el monto que debe pagar será; 20/100 * 3500 = $ 700
Entonces, la cantidad a pagar = 3500-700 = $ 2,800
Para la persona que compró $ 8000, monto a pagar = 20/100 * 8,000 = $ 1,600
Cantidad a pagar = 8000-1600 = 6400
