Answer:
C.5
Step-by-step explanation:
Fiona:
After t trials, she would have:
[tex]f(t) = 4.127(1.468)^t[/tex]
Karl:
After t trials, he would have:
[tex]k(t) = 0.897(1.992)^t[/tex]
At what number of trials would Fiona and Karl have the same number of beans?
This is t for which:
[tex]f(t) = k(t)[/tex]
So
[tex]4.127(1.468)^t = 0.897(1.992)^t[/tex]
[tex]0.897(1.992)^t = 4.127(1.468)^t[/tex]
[tex]\frac{(1.992)^t}{(1.468)^t} = \frac{4.127}{0.897}[/tex]
[tex](\frac{1.992}{1.468})^t = 4.6[/tex]
[tex](1.35695)^t = 4.6[/tex]
[tex]\log{(1.35695)^t} = \log{4.6}[/tex]
[tex]t\log{1.35695} = \log{4.6}[/tex]
[tex]t = \frac{\log{4.6}}{\log{1.35695}}[/tex]
[tex]t = 5[/tex]
So the correct answer is 5 trials, option C.
A tool box has the dimensions of 10 in by 4 in by 7 in. If Magnus plans to double all three dimensions to build a larger tool box, he believes he would double the volume of the tool box. Is he correct?
Answer: No. He's wrong.
Step-by-step explanation:
Since the tool box has the dimensions of 10 in by 4 in by 7 in. The volume will be:
= 10 × 4 × 7
= 280in³
When the dimensions are doubled, the new dimensions will be:
10 in = 10in × 2 = 20in
4in = 4in × 2 = 8 in
7in = 7in × 2 = 14in
The volume will now be:
= 20 × 8 × 14
= 2240in³
He is wrong, the volume isn't the double of the former tool box. The double of the former tool box will give (280in³ × 2) = 560in³. This is different from the new volume.
The Martinez family picked 3 lb of apples. Ana picked for those apples,
How many pounds of apples did Ana pick?
Answer:
C. 7/8
Step-by-step explanation:
The Martinez family picked 3 and one-half pounds of apples. Ana picked one-fourth of those apples. How many pounds of apples did Ana pick?
options
A. 1/4
B. 3/4
C. 7/8
D. 1 1/4
E. 3 1/8
Total apples the Martinez family picked = 3 1/2 pounds
Ana picked one-fourth of those apples.
Number of apples Ana picked = 1/4 × 3 1/2 pounds
= 1/4 × 7/2 pounds
= (1 * 7) / (4 * 2) pounds
= 7/8 pounds
Ana picked 7/8 pounds of apples
30 Points I NEED HELP ASAP MATH PROBLEM 7th Grade
Answer:
-45 =x
Step-by-step explanation:
1/5(4x-2.5) = 5(.4x+10) +3 1/2
Change all to decimal form
.2(4x-2.5) = 5(.4x+10) +3.5
Distribute
.8x - .5 = 2x +50 + 3.5
Combine like terms
.8x - .5 = 2x +53.5
Subtract .8x from each side
.8x-.8x - .5 = 2x-.8x +53.5
-.5 = 1.2x +53.5
Subtract 53.5 from each side
-.5 -53.5 = 1.2x +53.5-53.5
-54 = 1.2x
Divide each side by 1.2
-54/1.2 = 1.2x /1.2
-45 =x

(PLEASE HELP) 17. Jon read 3/8 of a book the
first day. 1/3 the second day.
and 1/4 the third day. On the
fourth day he finished the book.
What part of the book did Jon
read on the fourth day?
Answer:
[tex]\frac{1}{24}[/tex]
Step-by-step explanation:
24 is a common multiple so ill just use that as a denominator:
3/8 = 9/24
1/3 = 8/24
1/4 = 6/24
so then adding those up:
[tex]\frac{9}{24}[/tex] + [tex]\frac{8}{24}[/tex] + [tex]\frac{6}{24}[/tex] = [tex]\frac{23}{24}[/tex]
then whats left is 1/24 left to read, which cant be simplified so [tex]\frac{1}{24}[/tex]
Answer:
[tex]\frac{1}{24}[/tex]
Step-by-step explanation:
Let x be the part of the book he read on fourth day.
[tex]\frac{3}{8} + \frac{1}{3} + \frac{1}{4} + x = 1[/tex]
[tex]LCM \ of \ 8, 3 , 4 = 24.\ Therefore , \\\\[/tex]
[tex]\frac{3}{8} + \frac{1}{3} + \frac{1}{4} + x = 1\\\\\frac{9 + 8 + 6 + 24x}{24} = 1\\\\23 + 24x = 24\\24x = 1\\x = \frac{1}{24}[/tex]
[tex]On\ the\ fourth\ day\ he\ read\ \frac{1}{24} \ of\ the\ book\ to\ finish\ it.[/tex]

Answer:
Daniel's time: 3 minutes 45 seconds
Brandon's time: 3 minutes 27 seconds
Step-by-step explanation:
Well, 5 feet per every second so side A would be 327.6 / 3 = 109.2
then 489 / 5 = 97.8 add them two you get 207 seconds which is 3 minutes and 45 seconds for Daniel.
For Brandon you have to find the hypotenuse of the triangle which in short is 588.6 / 3 = 196.2

An article is bought for Rs 8600 and is sold at a profit of 20 %. Find its selling price.
Selling price = 8600 + Profit
Selling price = 8600 + ( 8600 × 20/100 )
Selling price = 8600 + ( 86 × 20 )
Selling price = 8600 + 1720
Selling price = Rs 10,320

annually.
Jing will not make any additional withdrawals or deposits. Which amount is closest
to the total balance of the two accounts at the end of 3 years?
Answer:
$864.88
Step-by-step explanation:

Now that you know how long it will take to buy your house from Assignment 4 and how much you need to save for retirement given different start times in your life (Assignment 5), you will now determine the time you will start saving for retirement. Add the savings time it takes to buy your house (2 years or the months you calculated, whichever is greater) to the age 22. By using the new budget from assignment 4, determine if you can afford the savings it takes from assignment 5 to retire with $1,000,000 based on your new age after buying your house. If you cannot, you have a choice, change your budget, or retire will less money.
For your answer, tell me your age, if you can afford in your budget to retire with $1,000,000. If you can, write your budget with the retirement savings added in. If you cannot, write that you cannot afford it and tell me if you are going to change your budget to afford it or simply retire with less money. Then write your budget with what savings you can afford. Remember, retiring with less money does not mean that you will have a smaller retirement income, it just means that you will pass on less than a million dollars to your children.

Answer:
Bettina= X(let)
Darren=3x
Jonathan=6x
120=X+3x+6x
X=12
so Bettina=12 yrs
Darren=36 yrs
Jonathan=72 yrs
Answer:
Step-by-step explanation:
Let Bettina's age be B.
Then Darren's age is 3 times Bettina's, or 3B.
Jonathan's age is twice that of Darren, i.e. 2 (3B) = 6B.
Altogether, the sum of their age is
B + 3B + 6B = 120 years
10 B = 120 years
B = 12 years.
Therefore
Bettina is 12 years old
Darren is 3 times as old as Bettina, so 36 years old.
Jonathan is twice that of Darren, so 72 years old.
Total = 72+36+12= 120 years, check! :)

Step-by-step explanation:
Write a short para based on how the pandemic has affected travelling.
Answer:
Unlike many of history’s great tragedies, the coronavirus pandemic never stunned us with one catastrophic event. Instead, the deadly problem quietly snaked its way around the world, devastating millions as it grew into a global health crisis since it first surfaced in November.
Our realities shifted slowly at first, and before we knew it, the coronavirus took over completely.
As we closed borders, canceled events and self-quarantined at home on a mass scale, the travel industry, as well as most other sectors, began to nosedive. The collective effort to save lives meant economic catastrophe for an industry that profits from people leaving their houses.
The wound inflicted by the pandemic on the travel industry is deep, and it hasn’t stopped bleeding yet.
In a May 20 call with analysts, Royal Caribbean Cruises chief executive Richard Fain recalled how drastically travel changed after the 9/11 terrorist attacks — and how the “new normal” eventually just became normal. He expects to see a similar phenomenon in the post-coronavirus world.
sorry it didnt let me send it so i took a lictire of it stay safe out there in the world wherever you are to let you know god is with you all the time if your in fear pray to him and he will take the fear away from you. anyways, stay safe and love you all!❤
