Can you estimate 7533

1 answer:

7 0

Based on your comment I assume you want to find 7,533 subtracted by 7,200. To estimate this, round 7,533 to the hundreds place, so 7,533 becomes 7,500.

7,500 - 7,200 = 300, using mental math.

Step-by-step explanation:

$\tt{ 1. \: \: 4 \frac{1}{9} + 1 \frac{1}{2}}$

⇢ $\tt{ \frac{37}{9} + \frac{3}{2} }$

⇢ $\tt{ \frac{37 \times 2 + 3 \times 9}{18} }$

⇢ $\tt{ \frac{74 + 27}{18} }$

⇢ $\tt{ \frac{101}{18}}$

⇢ $\boxed{ \tt{5 \frac{11}{18}} }$

---------------------------------------------------------

$\tt{ \: 2. \: \: 4 \frac{1}{2} \div \frac{3}{5}}$

⇢ $\tt{ \frac{9}{2} \times \frac{5}{3}}$

⇢ $\tt{ \frac{9 \times 5}{2 \times 3}}$

⇢ $\tt{ \frac{45}{6}}$

⇢ $\boxed{ \tt{7 \frac{3}{6}} }$

Fathi has \$1.10$1.10dollar sign, 1, point, 10 in his printing account. Each sheet of paper he uses reduces his printing account

Katena32 [7]

Answer:

$-4.90.

Step-by-step explanation:

Fathi has $1.10. Each sheet costs him $0.25. He wants to print 47 pages.

If he prints double sided, then he will use 47 / 2 = 23.5 sheets of paper. But he can't print a half-sheet, so he will use 24 sheets of paper.

Each sheet costs $0.25. 0.25 * 24 = 6. The printing will cost him $6.

Since he only has $1.10, his remaining balance will be 1.1 - 6 = -4.9. The balance on his printing account will be $-4.90.

Hope this helps!

Among 9 electrical components exactly one is known not to function properly. if 4 components are randomly selected, find the pro

seraphim [82]

Answer:

0.4444

Step-by-step explanation:

Use the following property to ease the calculation:

P(At least one)=1-P(None)

Total number of electrical components: 9

Number that does not function well :1

Number that functions well : 8

We have $^8C_4=70$ ways to to choose 4 good components from 8.

We have $^9C_4=126$ ways to choose 4 components from a total of 9.

If all function properly then none is bad, we $^1C_0=1$ way to do this.

P(At least one)= $1-\frac{^8C_4*^1C_0}{^9C_4}$

P(At least one)= $1-\frac{70*1}{126}$

P(At least one)=0.4444
