George practises his guitar for 1 1/5 hours per day on school days. On Saturday he increases to 2 1/2 times his normal time. How many hours does he practice on Saturdays.
Answer: 231/10
Step-by-step explanation: 11/5 x 21/2
= (11 x 21) = 231
= 231/5 x 2
= 231/10
Answer:
3 hours
Step-by-step explanation
It would be easier to convert your fractions into decimals.
1/5 is the same as 2/10. Since the denominator was multiplied by 2 then the numerator must be multiplied by 2 also.
2/10 in decimal form is 0.2
He would practice 1.2 hours per day on school days
On Saturday his practice is 2 1/2 times longer than 1.2 hours.
Convert 1/2 into decimal form. 1/2 is the same as 0.5.
So 2 1/2 is the same as 2.5
If you multiply the original time (1.2 hours) by 2.5, you'll know how long he practices on Saturday.
1.2 x 2.5 = 3 hours.
1.2
x 2.5
-------
60
24
------------
300
since you have 1 decimal place in the top number and 1 decimal in the bottom number, you must move your decimal 2 places to the left on your answer. Instead of 300, your answer becomes 3.00

If a rotation takes triangle CAT to C'A'T', what is C'T'?
Answers:
3
square root of 17
5
Cannot be determined
Answer:
its B
Step-by-step explanation:
the A point is in line with 10 squared and its in line with the 17 squared
The measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The graph shows the triangle CAT.
If a rotation takes triangle CAT to C'A'T',
then from the definition of rotation transformation the size and shape of the figure stays exactly the same.
Thus the measure of C'T' is same as CT.
⇒ [tex]C'T' =\sqrt{17}[/tex]
Hence we can conclude that the measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.

19) If manish saves 40% percent of his monthly income and he spends Rs. 15,000 every month, find his monthly income.
Answer:
Rs 25000
Step-by-step explanation:
Saves 40%
Spends 60%
Spending 60% = 15000
If 60% = 15000
Then divide it by 6 to get 10%
10% = 15000 ÷ 6
10% = 2500
100% = 25000
Aimee went to a stationary shop. She purchased 2 packs of red pens, 4 packs of black pens, and 3 packs of blue pens.
The cost of each pack of pens was $2.50. Which expression shows the total amount Aimee spent on the pens?
A ($2.50 x 2 x 4x3)
B $2.50 x (2+4+3)
C($2.50 x 2) + 3+4
D (52.50 +2 +4+3)
Answer:
A.
Step-by-step explanation:
The answer is B.
Each pack costs 2.50, so this means we can add all of our packs brought together, before multiplying. (2+4+3)=7. So our final equation should be 7 x 2.50 ,therefore B is our correct answer.

452.16 rounded to the nearest tenth
Answer: 452.2
Step by Step Explanation: Find the number in the tenth place 1 and look one place to the right for the rounding digit 6 round up if this number is greater than or equal to 5 and round down if it is less than 5
.
Rounding 452.16 to the nearest tenth gives us: 452.1.
Given that we need to round 452.16 to the nearest tenth,
We look at the digit in the hundredth place, which is the second decimal place, and round 452.16 to the nearest tenth.
One is the digit at the hundredth position.
We round down because 1 is less than 5, therefore.
Simply drop all the digits following the tenths place and leave the tenths place digit alone if you want to round down.
Rounding 452.16 to the nearest tenth, we obtain: 452.1.
Hence rounding 452.16 to the nearest tenth gives us: 452.1.

The force (F) needed to cause the acceleration (a) of an object mass, m, is given by the equation, F=ma where m is the object's mass. If a 12-Newton force causes the object to accelerate to 3 m/s2, what is that object's mass? The unit for this mass is kg.
Answer: the answer is 4 kg
because your force was 12
