The ratio of lions to tigers in the zoo is 3:5 if there are 9 lions how many tigers are there?
Answer:
1.) $54
2.) $21 left
3.) 15 tigers
Step-by-step explanation:
1.) If the original price of an item was $60, and it was reduced by 10%, that means it is now being sold at 90% of its original value.
To find out the new price, simply take the original value and multiply it by 90% (as a decimal).
60*.90=54
So the new price is $54
2.) This is simple subtraction. If you spend $45 on some CDs and $12 on a t-shirt, you spent a total of $57. Subtract $57 from your total of $78.
78-57=21
You are left with $21
3.) Ratios are all about multiplication. If the ratio of lions to tigers is 3:5, that means that the number of lions is going to be any factor of 3, as long as it corresponds to the same factor of 5 for the tigers.
For example, if there are 9 lions, there must be 15 tigers.
3*3=9
5*3=15
There are 15 tigers

The value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The expression:
= 2d + 4d - 9 - 7
Plug d = 5 in the above expression:
= 2(5) + 4(5)- 9 - 7
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= 10 + 20 - 9 -7
= 30 - 16
= 14
Thus, the value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

If you recall, x = 29
Just plug 29 into x for each angle
A = 3(29) = 87
B = 2(29) + 1 = 59
C = 29 + 5 = 34
Answer:
The value of angle C is 34°
Step-by-step explanation:
2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}
or, 6x + 6° = 180°
or, 6x = 180° - 6°
or, x = 174°/6
or, x = 29°
now,
value of angle C = x+5°
= 29°+5°
= 34°

Step-by-step explanation:
Given:
Total amount spend = $36
Cost of each slice = $2.25 per slice
Number of slices = x
Find:

Please Help. I need the answer for this question.
Answer: Choice A) $0.20
=======================================================
Explanation:
The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.
Divide this over 250 to get 50/250 = 0.20 dollars.
Their profit is $0.20 per pastry (ie 20 cents per pastry).
-------
You can think of it like this
50 dollar profit = 250 pastries
50/250 dollar profit = 250/250 pastries (dividing both sides by 250)
0.20 dollar profit = 1 pastry
That last equation tells us one pastry yields a profit of $0.20 or 20 cents.
Answer:
$0.20
Step-by-step explanation:
If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:
$100=250
? = 1
1×100/250 = $0.40 ( at purchase)
Then when resold, the profit is:
if 250 pastries= $150
1 pastry=?
$150× 1/ 250= $0.60
s0, the profit will be $0.60 - $0.40 = $0.20
