Bria asked her classmates whether they prefer math or science. Nine of her classmates said math and eight of her
classmates said science. Which inequality correctly compares the fraction who prefer science to the fraction who
prefer math?

Answers

Answer:

8/17<9/17

Step-by-step explanation:

Might be wrong with my answer but my logic was that if there are 9 students who prefer math and 8 who prefer science, that there are 17 students total. If there are 17 students total the denominator should be 17. Since 8 of them prefer science, we can write that as 8/17 because 8 out of the 17 students prefer science. Similarly we can write the number of students who prefer math as 9/17 because there are 9 students out of 17 who do.

A cup of coffee contains 140 mg of caffeine. If caffeine leaves the body at 10% per hour, how long will it
take for half of the caffeine to be eliminated from one's body?

Answers

Answer: 5 hours

Step-by-step explanation:

If 10% of 140 is 14. And if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from ones body, but for half of it to leave it would take 5.

It takes 5 hours to eliminate half of the caffeine from one's body.

Given that, a cup of coffee contains 140 mg of caffeine.

What is the percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

Now, 10% of 140

=0.1×140=14 mg

If 10% of 140 is 14 and if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from one's body, but for half of it to leave it would take 5 hours.

Therefore, it takes 5 hours to eliminate half of the caffeine from one's body.

hahahah i think i already did this for you buttttt

the denominator can be distributed to both parts of 9a and -3

The scale drawing's measurements will be 1 inch by 0.8 inch.

The scale is 1 in: 10 feet; because the deck's real width is 10 ft, the scale can read 1 inch. To evaluate the width: 1/10 = x/8

Cross multiply:
1*8 = 10*x
8 = 10x


Divide both sides by 10:
8/10 = 10x/10
0.8 = x

The scale drawing's width would be 0.8 inches.

B- what will Sarah earn when the tips are $350? Explain your strategy

C- what were the nightly tips when Sarah earned $81? Explain your strategy

Thank you :]

Answers

Answer:

A: E = 0.05t +56

B: $73.50

C: $60.05

Step-by-step explanation:

A) I'll just explain the equation in one go

Equation: E = 0.05t + 56

0.05 - This is meant to represent the 5% of tips

5% = 5/100

5/100 = 0.05

56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%

B+C) Since we already have the equation set up, we just need to plug in the variable, t.

B) E = 0.05(350) + 56

= 17.5 + 56

= 73.50

C) E = 0.05(81) + 56

= 4.05 + 56

= 60.05

Age If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times
Natalie's age, the result is 79. Write and solve a system of equations to find how old Fred and
Natalie are.
Fred is
years old. Natalie is
years old.

Answers

Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2


Combining equation 1 and 2, we get

( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12

Now, evaluating the value of Y in equation 1 we get,

X + 12 = 43
X = 31

Therefore, Fred is 31years old and Natalie is 12 years old.

Describe the environmental conditions that extremophiles are able to live in. Extremophiles were microbes that could only live in conditions that prevailed early in Earth's history when environments had high temperatures and pressure and lacked oxygen. Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions. Extremophiles can only survive in habitats where there are extreme changes in close proximity, such as hydrothermal vents at the bottom of the ocean, where water as hot as 300C emerges and mixes with 4C seawater. Extremophiles are able to tolerate extreme conditions found in space such as a near vacuum and temperatures in excess of 300C or several hundred degrees below 0C.
