Arjun's brother, Eli, adds 45 mL 45 mL45, start text, space, m, L, end text of chocolate syrup for every 6 66 ounces of hot water. Which hot cocoa is more chocolatey? Choose 1 answer: Choose 1 answer: (Choice A) A Arjun's hot cocoa (Choice B) B Eli's hot cocoa (Choice C) C The two cocoas are equally chocolatey.

Answers

Answer 1

Answer:

(Choice B) B Eli's hot cocoa

Step-by-step explanation:

Arjun makes hot cocoa, he adds 20 mL of chocolate syrup for every 3 ounces of hot water.

Ratio of chocolate syrup to hot water = 20 : 3

= 20 / 3

= 6.67

Eli adds 45 mL of chocolate syrup for every 6 ounces of hot water.

Ratio of chocolate syrup to hot water = 45 : 6

= 45 /6

= 7.5

The ratio of Eli's chocolatey hot cocoa is more than Arjun's chocolatey hot cocoa.

The correct answer is B Eli's hot cocoa

Answer 2

Answer:

Answer: The answer is the B Eli's hot cocoa .

Solve for x: |x − 2| + 10 = 12 x = 0 and x = 4
x = −4 and x = 0
x = −20 and x = 4
No solution

Answers

✯Let's solve this equation step-by-step!
✯is the question you've asked us today:
|x − 2| + 10 = 12

✯Add -10 to both sides:
|x−2|+10+−10=12+−10

✯Solve Absolute Value:
|x−2|=2

✯We know either:
x−2=2 or x−2=−2

(Possibility 1) x−2=2

(Add 2 to both sides) x−2+2=2+2

x=4

(Possibility 2) x−2=−2

(Add 2 to both sides) x−2+2=−2+2

x=0

✯So since we have gotten x=4 and x=0 you answer shall be:

B. x=4 and x=0

✯I hope this helps!✯

first you can add -10 on both sides so you gonna have :
l x - 2 l = 12 - 10 ⇒ l x - 2 l = 2 now because of the absolute value you should say :
1) x - 2 = 2 ⇒ x = 2 + 2 ⇒ x = 4

2) x- 2 = -2 ⇒ x = -2 +2 ⇒ x = 0
so the answer is first one :)))
i hope this is helpful

There are two newborns, Gary and Eric. The future lifetime of Gary is uniformly distributed between 0 to 60 years. The future lifetime of Eric is uniformly distributed between 0 to 40 years. Their future lifetimes are independent. Calculate the probability that Gary dies first

Answers

Answer:

$\text{The probability that Gary dies first = }(1)/(3)$

Step-by-step explanation:

To find the required probability,

We can split the 40 years of Eric into very small pieces of time dt. Now, If Eric dies at time t and Gary dies before Eric, the probability is :

$(t)/(60)* (dt)/(40)=(t\cdot dt)/(2400)$

Hence the probability that Gary dies first is given by :

$=\int_(0)^(40)(t)/(2400)dt \n\n= (1)/(3)$

Which statement correctly describes a property of white light?A. It makes all objects appear white.

B. It contains different wavelengths of visible light.

C. It allows light waves to be transmitted.

D. It contains all waves on the electromagnetic spectrum.

Answers

The statement that correctly describes a property of white light is that it b) contains different wavelengths of visible light.
When white light strikes any object that reflects any wavelength of visible light, that object appears to be the color that it reflects.

The correct statement out of the 4 choices for this question is the property of white light contains different wavelengths of visible light.

84 is 15% of what number

Answers

p% $= (p)/(100)$

$(15)/(100) = (15/5)/(100/5) = (3)/(20)$

$(3)/(20) *x=84$ ⇒ $3x=84*20$
$3x=1680$
So, x= $(1680)/(3) = 560$

$\boxed {x=560}$

x*15/100=84
x=84*100/15
x=8400/15
x=560
therefore the number is 560

Renata moved to her new home a few years ago. Back then, the young oak tree in her back yard was 1 9 0 centimeters tall. She measured it once a year and found that it grew at a constant rate. 3 years after she moved into the house, the tree was 2 7 4 centimeters tall.

Answers

It would grow 28 centimeters each year. 274-190=84 which is the difference from 3 years. You would then divide the 84 between three different years to get 28.
