A 63-year-old man has rowed around the world in his living room, according to a newspaper story. On a rowing machine that he received for his 50th birthday, he logged 24084 miles.
The number of miles per year is calculated as,
⇒ 24,084 / (63 - 50)
⇒ 24,084 / 13
⇒ 1852.61 ≈ 2,000
The number of miles per year that he has rowed since he was given the machine will be Roughly 2000. Then the correct option is D.

Jasmine spends exactly £120 on three types of plants: poisoned ivy, deadly nightshade and triffids. Poisoned ivy plants cost £2 each, deadly nightshade plants cost £9 each and triffids cost £12 each. She buys twenty plants in total, including at least one of each type. How many triffids did she buy?
Answer:
9/5
Step-by-step explanation:
2×9×12=216 so216/120 =9/5
Jasmine bought approximately 4 triffids.
We have,
We know that Jasmine bought a total of twenty plants and that she purchased at least one of each type.
Let's assume she bought x triffids.
From the given information, we can determine the number of poison ivy plants and deadly nightshade plants she bought:
Number of poisoned ivy plants = Total plants - (Number of deadly nightshade plants + Number of triffids)
Number of poisoned ivy plants = 20 - (1 + x) = 19 - x
Number of deadly nightshade plants = Total plants - (Number of poisoned ivy plants + Number of triffids)
Number of deadly nightshade plants = 20 - (1 + (19 - x)) = 20 - (20 - x) = x
We can now set up an equation based on the total amount Jasmine spent:
Total cost = (Number of poisoned ivy plants * Cost per poisoned ivy plant) + (Number of deadly nightshade plants * Cost per deadly nightshade plant) + (Number of triffids * Cost per triffid)
£120 = (19 - x) * £2 + x * £9 + x * £12
Simplifying the equation:
£120 = £38 - £2x + £9x + £12x
£120 = £38 + £19x
£82 = £19x
Dividing both sides of the equation by £19:
£82/£19 = x
x ≈ 4.32
Since we can't have a fractional number of plants, we'll round down to the nearest whole number.
Therefore,
Jasmine bought approximately 4 triffids.

A rectangle that is 4 inches by 6 inches has been scaled by a factor of 7 . What are the side lengths of the scaled copy ?
Step-by-step explanation:
step one:
The question is incomplete it did not specify weather the scale was a reduction or an increase in the dimension of the rectangle.
step two:
let us assume it was to be an increase i.e 7x
the length would be 4*7= 28 inches
the width would be 6*7= 42 inches
step three:
Also, we assume it was to a decrease i.e 7x
the length would be 4/7= 0.57 inches
the width would be 6/7= 0.85 inches
What is the solution to -3m = -15
Answer:
[tex]m=5[/tex]
Step-by-step explanation:
[tex]-3m=-15[/tex]
Divide both sides by -3:
[tex]\frac{-3m}{-3}=\frac{-15}{-3}[/tex]
[tex]m=5[/tex]
Answer:
[tex]m = 5[/tex]
Step-by-step explanation:
Solve for [tex]m[/tex] :
[tex]-3m = -15[/tex]
-Take [tex]-3m[/tex] and divide it on both sides of the equation:
[tex]\frac{-3m}{-3} = \frac{-15}{-3}[/tex]
[tex]m = 5[/tex]
Therefore, the value of [tex]m[/tex] is [tex]5[/tex].
Four times the smallest of three consecutive integers is three more than three times the largest. What is the middle integer?
Let, first integer is x.
Therefore, other two are x+1 , x+2 .
Now, mathematical expression of given conditions is :

In a social club, the ratio of men to women is 5: 7. There are 595 women. How
many men are there?
Answer:
52
you take 5 ÷ it by 7 the ×it by 595
A ratio is an ordered pair of numbers a and b written as a/b where b is not equal to zero.
if the number of women in the social club is 595 then the number of men in the social club is 425.
What are ratios and proportions?A ratio is an ordered pair of numbers a and b written as:
a / b where b does not equal 0.
A proportion is an equation in which two ratios are equal to each other.
We have,
The ratio of men to women:
= 5:7
= 5/7
Let,
The number of men = 5x
The number of women = 7x
Now,
If the number of women = 595
We have,
7x = 595
Multiplying both sides by 5/7 we get,
5/7 x (7x) = 5/7 x 595
5x = 5/7 x 595
5x = 5 x 85
5x = 425
This means if there are 435 men in the social club if the number of women is 595.
Thus if the number of women in the social club is 595 then the number of men in the social club is 425.

Aubrey is saving up to buy a new jacket. She already has $85 and can save an
additional $7 per week using money from her after school job. How much total
money would Aubrey have after 8 weeks of saving? Also, write an expression that
represents the amount of money Aubrey would have saved in w weeks.
I
Aubrey can save $7 per week, so she can save $7 x 8 or $56
in 8 weeks. Because she already had $85 to begin with, the
total amount saved would be $56 + $85 or $141.
Answer:
[tex]Total\ Savings = 85 + 7 w[/tex] --- In w weeks
[tex]Total\ Savings = \$141[/tex] --- In 8 weeks
Step-by-step explanation:
Given
[tex]Available\ Amount = \$85[/tex]
[tex]Weekly\ Savings = \$7[/tex]
[tex]Number\ of\ weeks = 8[/tex]
Required
Determine the amount of savings in w weeks
This can be calculated as thus:
[tex]Total\ Savings = Available\ Amount + Weekly\ Savings * Number\ of\ weeks[/tex]
In this case;
w = Number of weeks
So, we have:
[tex]Total\ Savings = 85 + 7 * w[/tex]
[tex]Total\ Savings = 85 + 7 w[/tex]
When w = 8, we have
[tex]Total\ Savings = 85 + 7 * 8[/tex]
[tex]Total\ Savings = 85 + 56[/tex]
[tex]Total\ Savings = \$141[/tex]
