Alicia cashed her paycheck and used half her earnings to take three friends to dinner. She spent $42.15 on dinner and she brought home more than $20.00. Write an inequality to represent the situation, using x to represent the amount of Alicia's paycheck

Answers

Answer 1
Answer:

If you would like to write an inequality to represent the situation, you can do this using the following steps:


x ... the amount of Alicia's paycheck

x/2 - $42.15 >= $20
x/2 >= $20 + $42.15
x/2 >= $62.15     /*2
x >= $62.15 * 2
x >= $124.3

The correct result would be x >= $124.3.

How much time has elapsed between 12:11:30 and 15:24:55

Answers

Time elapsed = Final time - initial time

= 15:24:55 - 12:11: 30

= 3:13: 25

or, 3 hours, 13 minutes and 25 seconds has been elapsed.
We'll 15-12 = 3 , 24-11 =13 , and 55-30 = 25 so 3:13:25

write an equation for an exponential function, in the form y=axb^x, whose graph passes through the coordinate points (1, 7.5) and (3, 16.875).

Answers

7.5 = a*b^1

16.875 = a* b^3

Divide the last equation by the former

16.875/7.5  = b^ (3-1)

2.25 = b^(2)

extract square root from both sides

b = 1.5

From 7.5 = a*b ⇒ a = 7.5/ (1.5) = 5

The requested function is y = 5 (1.5)^x

Lois is 3 years older than Oscar. The sum of their ages is no more than 20. Write an inequality that can be used to represent this situation, where x represents Oscar’s age.

Answers

  • Let Oscar be x years old
  • Lois is x+3 years old

ATQ

\n \sf\longmapsto x+x+3\leqslant 20

\n \sf\longmapsto 2x+3\leqslant 20

\n \sf\longmapsto 2x\leqslant=17

\n \sf\longmapsto x\leqslant (17)/(2)

Answer:

let Oscar's years be x

• Oscar → x

• Lois → (x+3)

{ \rm{x + (x + 3) \leqslant 20}} \n  \n { \boxed{ \rm{2x + 3 \leqslant 20}} }

Solve this proportion 10/8=n/10

Answers

The solution to the expression is n = 12.5.

We have,

To solve the expression 10/8 = n/10, we can use cross-multiplication.

Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction.

10/8 = n/10

10 x 10 = 8 x n

100 = 8n

To solve for n, we divide both sides of the expression by 8:

100/8 = n

n = 12.5

Therefore,

The solution to the expression is n = 12.5.

Answer:

n=12.5

Step-by-step explanation:

10/8=n/10

/8 to /10 is *1.25

so 10/ to n/ would also be *1.25

10*1.25 is 12.5 so n=12.5

Where is the genetic information found in eukaryotic cells?lysosomes

nucleus

mitochondria

ribosomes

Answers

The answer is nucleus.

Explanation:

The nucleus is like the brain of the cell, where genetic information is located and stored. It can’t be the mitochondria because that’s where ATP (energy) is generated. It can’t be the ribosomes because that is the area of informational decoding. It can’t be the lysosomes because that is the area of virus destruction.
