The answer is 56. You would get this by multiplying 28 x 2. It's really simple. She gave HALF of her cookies so you would need to multiply.
Step-by-step explanation:
3. The length of the rectangle is 3x and width is x+5
Now,
Area of rectangle=l×b
=3x(x+5)
=3x^2+15x(option d.)
4. 2/3x-4=20
2x/3=20+4
2x/3=24
2x=24×3
2x=72
x=72/2
x=36(option d.)
Answer:
<u>5x + 6</u>
Step-by-step explanation:
<u>To Do</u>
- Creating an algebraic expression that always results in 6 more than a multiple of 5 if the variable is an integer
<u />
<u>Solution</u>
- Let the variable be x
- Multiple of 5 ⇒ 5x
- 6 more ⇒ +6
- Expression ⇒ <u>5x + 6</u>
A = lw
A = 5.45 × 3.275
A = 17.84875
The area of the frame (without rounding) is 17.84875.
Answer:
The amount needed such that when it comes time for retirement is $396721.78.
Step-by-step explanation:
Given : An individual can make monthly withdraws in the amount of $2,154 for 30 years from an account paying 5.1% compounded monthly.
To find : The amount needed such that when it comes time for retirement?
Solution :
Using the formula of monthly payment,
Monthly payment,
Discount factor D=\frac{1-(1+i)^{-n}}{i}
Where,
Amount = ?
Monthly payment M=$2154
Rate r= 5.1%=0.051
Time = 30 years
Substitute all the values,
Monthly payment,
Nearest cent,
Therefore, the amount needed such that when it comes time for retirement is $396721.78.
