The length of a rectangular garden is 8 feet longer than its width. The garden's perimeter is 188 feet. Find the width of the garden.
Answer:
44 Feet
Step-by-step explanation:
Trust me
Answer:
Width = 43 feet
Step-by-step explanation:
Given the 188-feet perimeter of a rectangular garden, for which its length is 8 feet longer than its width:
We can express the length of the rectangular garden as: 8 + W.
Hence, in order to solve for the length and the width of the rectangular garden, use the following formula for the perimeter of a rectangle:
Perimeter (P) = 2(L + W) or 2L + 2W = 188 feet
Length (L) = 8 + W
Width (W) = W
Substitute these values into the perimeter formula to solve for the value of the rectangular garden's dimensions:
P = 2L + 2W
188 feet = 2(8 + W) + 2W
Distribute 2 into the parenthesis, (8 + W):
188 = 16 + 2W + 2W
Combine like terms:
188 = 16 + 4W
Subtract 16 from both sides:
188 - 16 = 16 - 16 + 4W
172 = 4W
Divide both sides by 4 to solve for W:
[tex]\LARGE\mathsf{\frac{172}{4}\:=\:\frac{4W}{4}}[/tex]
W = 43
Therefore, the width of a rectangular garden is 43 feet.
Since we determined that the length is 8 + W, then it means that the length of the rectangular garden is 51 feet.
Verify the dimensions:Double-check whether we have the correct dimensions for the rectangular garden by substituting the length (L) = 51 feet, and the width (W) = 43 feet, into the perimeter formula:
P = 2L + 2W
188 feet = 2(51) + 2(43)
188 feet = 102 + 86
188 feet = 188 feet (True statement). This means that we have the correct dimensions for the rectangular garden.
Answers:Therefore, the width of a rectangular garden is 43 feet.
Find the missing angle
Answer:
x=33
Step-by-step explanation:
The sum of the angles of a triangle is 180
23+124+x = 180
147+x =180
x = 180-147
x =33
Answer: 33
Step-by-step explanation:
A triangle is equal to 180 degrees. So you add 124 and 23 to get 147. You would then subtract 180-147=33 and then you have your answer. Hope this helps!

Anna went to the playground at 4:05 P.M. She played on the slide for 30 minutes and the swings for 55 minutes, then went home. What time was it when Anna left the playground?
Include A.M. or P.M. in your answer (for example, 11:58 A.M.).
Answer:
5:30 P.M.
Step-by-step explanation:
30 (slide) minutes and 55 (swings) minutes. These numbers (time-wise) total up to an hour and 25 minutes. Adding this to 4:05 P.M. would mean that she left the playground at 5:30 P.M.
Hope this helps.

Step-by-step explanation:
As you have noticed, the difference between the end values of x is 20-4 = 16, and the differences in each interval are 4.
The difference between the end values of y is 12 -(-4) = 16, so the differences in each interval will also be 4.

First one: F(x) = -(3/4)X +6
Second graph: F(x) = -(3/4X) + 6
Amy graphed a point to represent the absolute value of a number on a number line. If the original number is less than −10, describe all the possible values for the point Amy graphed on the number line.
Answer:
x>= 11 or x>10
Step-by-step explanation:
Absolute value can be used to represent the positive counterpart of a negative number. In this case, we are asked to find a number that is less than -10, meaning from -11 to negative infinity. Since we are asked to take absolute value, we would take |-11| which equals 11, and |-∞| = ∞.
So Amy graphed a value on the number line that is greater than or equal to 11, or any value greater than 10.
*Infinity is not a real number, it represents the largest number possible, which doesn't exist since numbers can continue on forever, so it can be disregarded.*

Last year, the school library had a total of x books. Over the summer, the library acquired another 36 books and now has a total of 2,284 books. Which
equation could be used to find x, the number of books the library had last year
Answer:
the last year the eschool has 2248 books
Step-by-step explanation:
2284-36=2248
Answer:
2,248=2,284-36b
Step-by-step explanation:
since the library acquired(added) 36 books the library now has a total of 2,284 books.
To find out how many books the library had before they added 36 books you need to set up a simple equation.
2,284-36=2248
since you now know that before summer the library had 2,248 books you would write an equation and when you solve it you should get 2,248. The equation should be 2,248=2,284-36b. b representing the total number of books that were added.

If f(x) = x2 + 5, find f(-9).
Answer:
f(-9) = 86
Step-by-step explanation:
Hi there!
f(x) = x² + 5
To find f(-9), replace x with -9:
f(-9) = (-9)² + 5
f(-9) = 81 + 5
f(-9) = 86

Find the measure of two complementary angles if the measure of one is 15 degrees more than twice the measure of the other
Answer:
25 and 65
Step-by-step explanation:
Let one of the angles be x.
So, the other angle is 15 + 2x
complementary angles add up to 90 degrees.
so, we have
x + 2x + 15 = 90
3x + 15 = 90
Subtract 15 from both sides
3x = 75
solve for x
x = 25
so, the angles are 25 and 65
2 complementary angles sum up to 90°.
Take one angle as 'x'. Then, the other angle will be '15 + 2x'.
15 + 2x + x = 90°
15 + 3x = 90°
3x = 90 - 15
3x = 75
x = 75/3
x = 25°.
Measure of 1st angle (x°) = 25°
Measure of 2nd angle (15 + 2x°) = 15 + 2*25 = 65°.
=》 The 2 complementary angles are 25° & 65°.

Hey everyone! This questions is tricky for me so can anybody help me out?

g(x) = 2x^2
for g(- 4), you just plug in - 4 for x
g(- 4) = 2(- 4)^2
g(- 4) = 2(16)
g(- 4) = 32
Answer:
g(-4) = 32
Step-by-step explanation:
Given the quadratic function, g(x) = 2x², finding the output value given g(-4) involves substituting the value of the input, x = -4, into the function.
Solution:g(x) = 2x²
g(-4) = 2(-4)² = 2(-4)(-4)
g(-4) = 2(16)
g(-4) = 32
Therefore, g(-4) = 32.
Find the rate if a principal of $1,800 earned $378 interest in 6 years
Answer:
Interest rate (r ) = 0.035 or 3.5%
Step-by-step explanation:
Given the principal amount of $1,800, and an interest payment of $378 earned in 6 years:
Use the simple interest formula and algebraically solve for variable, interest rate, r :
I = P × r × t
Where:
I = interest payment = $378
P = principal amount = $1,800
t = time (in years) = 6
r = interest rate
Divide both sides by P × t to isolate r :
[tex]\displaytext\sf{\frac{I}{P\:\times\:t}\:=\:\frac{P\:\times\:r\:\times\:t}{P\:\times\:t}}[/tex]
[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{I}{P\:\times\:t}}[/tex]
Substitute the given values into the formula for the interest rate:
[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{378}{1800\:\times\:6}\:=\:\frac{378}{10800}}[/tex]
Interest rate (r ) = 0.035 or 3.5%
Therefore, the interest rate is 3.5%.
