Answer:
L = 20 inches
Step-by-step explanation:
w = width
L = length
area = 120
W x L = 120
L - 8 = 2W then L = 2W + 8
substitute for L:
W x (2W + 8) = 120
2W² + 8W -120 = 0
(2W - 12)(W + 10) = 0
2W-12 = 0
2W = 12
W = 6
L = 20
if an arithmetic sequence has a1=5 d=-2 and n=18 what is sn?
Answer:
sn = -216
Step-by-step explanation:
If an arithmetic sequence has a1=5 d=-2 and n=18 what is sn?
The formula for sn is given as:
sn = n/2[2a +(n - 1)d]
Hence, we fill in our values
sn = 18/2 [2 × 5 + (18 - 1)-2]
sn = 9 [ 10 + (17)-2]
sn = 9 [10 - 34]
sn = 9 × -24
sn = -216

24 59' 60'' is equivalent to what degrees
Answer:
25 degrees
Step-by-step explanation:
The computation is shown below:
24°59'60" = 24°+59'+60"
Now
As we know that
1'=60"
i.e. (1 minute = 60 seconds)
so,
24°+59'+60" = 24°+59'+1'
=24°+60'
Also,
1°=60'(1 degree=60 seconds)
= 24°+1°
=25°

Answer:
a. 10%
b. 37.57
c. What the coin was worth 3 years prior to 2000
Step-by-step explanation:
a. The equation for exponential growth is v(t) = P(1+r)^t. Where v(t) is the total amount, P is the principal, r is the rate of growth, and t is time in years. For part a, you need to find r, the rate. In this situation, r is equal to .1, which is equal to 10%.
b. To find part b simply solve the equation for when t equals -3. So the equation should look like [tex]v(t)=50(1.1)^{-3}[/tex]. When this is plugged into a calculator or solved by hand the total equals $37.57.
c. In this, t equals the time in years since 2000. Since -3 is negative, this must take place 3 years before 2000. Therefore, v(-3) must represent the value of the coin in 1997.

Simplify the following expression:
6(3x) − 2y + 3z + 12(4x) − 9y
The simplified expression is 66x - 11y + 3z To simplify the given expression, we can combine like terms:
6(3x) − 2y + 3z + 12(4x) − 9y
Simplifying each term:
18x − 2y + 3z + 48x − 9y
Combining the like terms:
(18x + 48x) + (-2y - 9y) + 3z
Simplifying further:
66x - 11y + 3z
Therefore, the simplified expression is 66x - 11y + 3z.

Which of the following are the most compatible numbers for dividing 8,652 = 45?
Answer:
2
Step-by-step explanation:
None of the given numbers are compatible for dividing 8,652 by 45.
What are compatible numbers?Compatible numbers seem numbers that are simple to work with mentally and can be utilized to estimate or validate mathematical solutions. Compatible numbers are frequently selected based on how close they are to the numbers involved in the situation.
We can utilise divisibility principles to remove some alternatives when determining which integers are the most compatible for dividing 8,652 by 45.
The divisibility rule for 45 states that a number has to be divisible by both 9 and 5. As a result, we want to identify 9 factors that also divide 8,652.
The divisibility rule for 9 states that the sum of a number's digits must be divisible by 9 in order for the number to be divisible by 9.
So, add the figures 8,652 together: 8 + 6 + 5 + 2 = 21.
We can't divide 8,652 by 45 evenly since 21 isn't divisible by 9.
Therefore, none of the given numbers are compatible for dividing 8,652 by 45.

what scale factor can be applied to cone 1 to make cone 2?
a. 4/3
b. 3/4
c. 3/2
d. 2/3
Answer:
2/3 can be applied to cone 1 to make cone 2.
Step-by-step explanation:
2/3=0.666666..
Any number between 0-1 can be used to "shrink" the object/volume.
- Divide a dimension of Cone 2 by the corresponding dimension of Cone 1 (2÷3)
The scale factor of the cone 1 to cone 2 will be 3/2. Then the correct option is C.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
There is no effect of dilation on the angle.
The cone 1 has the base radius of the circle is 3 units and height of the cone is 9 units.
The cone 2 has the base radius of the circle is 2 units and height of the cone is 6 units.
Then the scale factor of the cone 1 to cone 2 will be
Scale factor = (Radius of cone 1) / (Radius of cone 2)
Scale factor = 3 / 2
Thus, the scale factor of the cone 1 to cone 2 will be 3/2.
Then the correct option is C.
More about the dilation link is given below.
