The perimeter of a rectangle is 82 meters. If the length of the rectangle is 20 meters more than the width
of the rectangle, find its length and width.
Answer:
30.5 meters
10.5 meters
Step-by-step explanation:
x = length
y = width
x = y + 20
2x + 2y = 82 (the perimeter of a rectangle)
using the first equation as substitute in the second equation we get
2×(y + 20) + 2y = 82
2y + 40 + 2y = 82
4y = 42
y = 42/4 = 21/2 = 10.5 meters
x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters
A new popular midsize car has a retail price of $25,000. The midsize car's value M(t) is given by the exponential model M of t is equal to 25,000 times the quantity four fifths to the power of t where t represents the time in years. Identify the domain, in yearly intervals, that contains all the years the car's value is less than $1,000.
[13, ∞)
[14, ∞)
[15, ∞)
[16, ∞)
Answer:
Its C
Step-by-step explanation:
Just finished the homework and got it right
Using exponential functions, it is found that the correct option is given by: [15, ∞)
-------------------------
The exponential function given in this exercise is:
[tex]M(t) = 25000(\frac{4}{5})^t[/tex]
-------------------------
The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:
[tex]M(t) < 1000[/tex]
Thus, we have to solve the exponential inequality.
[tex]M(t) < 1000[/tex]
[tex]25000(\frac{4}{5})^t < 1000[/tex]
[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]
[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]
[tex]-0.0969t < -1.39794[/tex]
[tex]0.0969t > 1.39794[/tex]
[tex]t > \frac{1.39794}{0.0969}[/tex]
[tex]t > 14.43[/tex]
Rounding, t greater than 15 years, and the correct option is:

hope this helpsThe movie ended at 7:05 p.m. and lasted 2 hours 40 minutes. What time did the movie begin?
Answer:
4 : 25pm
Step-by-step explanation:
If the movie ended at 7:05p.m, and the movie is as long as 2 hours 40 minutes, therefore the starting time is 2 hours 40 minutes earlier than the ending time
Therefore
7:05 - 2 hours and 40 minutes
= 4 : 25pm

Answer:
d. √16, 4.23_23, √18, 4 2/3
Step-by-step explanation:
There are a couple of different ways to compare these numbers. Maybe one of the most straightforward is to find the decimal equivalent, rounded to hundredths.
4.23_23 ≈ 4.23
4 2/3 ≈ 4.67
√18 ≈ 4.24
√16 = 4.00
These can be sorted least-to-greatest by putting the first number (4.23) between the last two (4.00, 4.24) and reading the new list last-to-first.
4.00, 4.23, 4.24, 4.67 ⇔ √16, 4.23..., √18, 4 2/3
_____
Additional comment
Another way to work this problem is to square the numbers not under a radical. 4.23...² ≈ 17.91 and (4 2/3)² ≈ 21.78. The ordering of the squares is the same as the ordering of their square roots.
16 < 17.91 < 18 < 21.78 ⇔ √16 < 4.23... < √18 < 4 2/3

Please help me out!!!!
Answer:
All real numbers
Step-by-step explanation:
4(x+1) = 4x+4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
Solution:
Let's find the required solution,
→ 4(x + 1) = 4x + 4
→ 4x + 4 = 4x + 4
→ (4x - 4x) + 4 = 4
→ 4 = 4
→ LHS = RHS
The answer is all real numbers.

Will three sides of any length create a triangle?
plzz someones help me plz I will mark brainlest diameter is 1 3/4
Answer:
The area of the circle is 2.41 in^2
Step-by-step explanation:
You are given the diameter, 1 3/4. This is a mixed fraction, so let's convert that into decimal.
1 3/4 = 7/4
7/4 = 1.74
Now, let's use the area of circle formula.
A = 1/4πd^2
A = 1/4 * π * 1.75^2
A ≈ 2.40528
Let's round the area to the nearest hundredth.
2.40528 = 2.41
A and B are complementary and B and C are supplementary.
9. If mA 48", then mB= ? and mC = ?.
10. If mB 83, then mA = ? and mC = 2.

12. If mA = 25. than mB= ? and mC = ?.
9. if mA = 48° , then
mB = 90° - 48° = 42°mC = 180° - 42° = 138°10. if mB = 83°, then
mA = 90° - 83° = 7°mC = 180° - 83° = 97°11. if mC = 127°, then
mB = 180° - 127° = 53°mA = 90° - 53° = 37°12. if mA = 25°, then
mB = 90° - 25° = 65°mC = 180° - 65° = 115°Find the discriminate, number of roots and solve the quadratic equation using the quadratic formula -my answers are pribably wrong
Answers:
discriminant = dnumber of roots = esolutions = g=================================================
Explanation:
Let's compute the discriminant. Here we have a = 1, b = 1, c = -2
d = b^2 - 4ac
d = 1^2 - 4(1)(-2)
d = 9
The fact that d > 0 tells us we have two different real number solutions.
------------------------
We can use the quadratic formula to solve, or we can factor. I'll use the factor method.
x^2 + x - 2 = 0
(x - 1)(x + 2) = 0
x-1 = 0 or x+2 = 0
x = 1 or x = -2
