If a right triangle has side lengths x + 9, x + 2, x + 10 is the hypotenuse, find the value of x

1 answer:

4 0

The total perimeter is 3x +21= ? first we isolate the variable by subtracting 21 on both sides. we then get 3x=21 now we divide by three on both sides and we find that x=7 to check this plug this in to x+9 x+10 and x +2 and see if x+10 is the hypotenuse.

Why does the unit of time enter twice in the unit of acceleration?

AfilCa [17]

Because the speed has formula of distance divide time = m/s
and the acceleration is speed /time so (m/s)/s = m/(s*s) = m/s^2

hope this is understandably sure easy for you

Question:

James has 14,500g of sand in his sandbox. He brings home another 7,400g of sand from the beach to add to his sandbox. How many kilograms of sand does James have in his sandbox now?

Answer:

The quantity of sandbox James has is 21.9kg

Step-by-step explanation:

Given

Initial quantity of sandbox = 14,500 g

Additional quantity = 7,400 g

Required

Total quantity of sandbox in kg

Tp get the total quantity of sandbox, we simply add in the initial and additional quantity of sandbox together;

This is represented mathematically as follows;

Total = Initial Quantity + Additional Quantity

Total = 14,500 g + 7,400 g

Total = 21,900 g

But the question says the answer should be in kg

1000 g is equivalent to 1 kg

21,900 g will be equivalent to $\frac{21,900}{1,000} kg$

$21,900g = \frac{21,900}{1,000} kg$

$21,900g = 21.9 kg$

Hence, the quantity of sandbox James has is 21.9kg

If she saves 1$ the first week 3$ the season week 9$ the third week how much will she save in 5 weeks

ycow [4]

Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).

Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.

Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.

Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks
