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)
Answers
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.

Describe the decimal multiplication equation and product shown by the model. Include details of where each part of the equation is found on the model.
Answers
The question is an illustration of multiplication model.
The multiplication model is: [tex]\mathbf{0.90 \times 0.10 =0.09}[/tex]
From the figure, the shaded portions are:
[tex]\mathbf{Green = \frac{90}{100}}[/tex]
[tex]\mathbf{Orange = \frac{10}{100}}[/tex]
So, the multiplication model represents:
[tex]\mathbf{Model =Green \times Orange}[/tex]
This gives
[tex]\mathbf{Model =\frac{90}{100} \times \frac{10}{100}}[/tex]
Express as decimal
[tex]\mathbf{Model =0.90 \times 0.10}[/tex]
[tex]\mathbf{Model =0.09}[/tex]
Hence, the multiplication model is:
[tex]\mathbf{0.90 \times 0.10 =0.09}[/tex]

19) If manish saves 40% percent of his monthly income and he spends Rs. 15,000 every month, find his monthly income.
Answers
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

What is the value of x in the equation 3x/4=24
Answers
Answer:
X= 32
Step-by-step explanation:
Answer:
X = 32
Step-by-step explanation:
If you do 24 x 4 you will get 96.
From there you have to divide 3 by 96, since 3 times x has to equal to 96. Since 24 x 4 is 96 and you need to divide 3x by 4.
After you do 96/3 you will get 32. Thus the answer being 32.

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.
Answers
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

The ratio of the number of apples to the number of oranges is 5:2 . There are 18 more apples than oranges. If 24 oranges are added, what will be the new ratios of apples to the numbers of orange?
Answers
Answer:
5 : 6
Step-by-step explanation:
The ratio of apples to oranges is 5 : 2 = 5x : 2x ( x is a multiplier )
There are 18 more apples than oranges , that is
5x = 2x + 18 ( subtract 2x from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
There are 5 × 6 = 30 apples and 2 × 6 = 12 oranges
The number of oranges is increased by 24, to 12 + 24 = 36 , then
30 apples : 36 oranges ( divide both parts by 6 )
= 5 : 6

Answers
Answer:

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.
