An square has side lengths that measure x + 7 inches. the perimeter of the square is 18.6 inches. The value of x is -2.35 inches.
To find the value of x, we can set up an equation based on the given information.
The perimeter of a square is calculated by multiplying the length of one side by 4. In this case, the perimeter is given as 18.6 inches, so we can write:
4 × (x + 7) = 18.6
Simplifying the equation:
4x + 28 = 18.6
Next, we can isolate the variable x by subtracting 28 from both sides:
4x = 18.6 - 28
Simplifying further:
4x = -9.4
Finally, we divide both sides of the equation by 4 to solve for x:
x = -9.4 / 4
The value of x is -2.35 inches.

. Chris read 25 books in 135 days. At this rate, in how many days will he read another 5 books? Another 10 books?
Answer:
5 books - 27 days
10 - 54 days
15 books - 81 days
Step-by-step explanation:
First, you need to find how many days it takes to read one book, to do this, simply divide 135 by 25 (135/5=5.4). Then, you multiply that number by the amount of books it wants to know how long it would take him to read (5 and 15 since it asks "another 10". It could also be 54 if it was asking how many for 10 books not including the 5 he would have read). 5*5.4=27, 10*5.4=54, and 15*5.4=81.

Answer:
C
Step-by-step explanation:
✔️First, solve for r:
r/2 ≤ 3
Multiply both sides by 2
r/2 × 2 ≤ 3 × 2
r ≤ 6
This implies that possible value of r is equal to 6 or less than 6.
Graphing this on a number line, the line with a shaded circle, indicating that 6 is included, starts at 6 and points to the left.
This indicates that value of r ranges from 6 and below.
The graph is C.

A meteorologist found that the rainfall in Campbell during the first half of the month was 3/10 of an inch. At the end of the month, he found that the total rainfall for the month was 1/2 of an inch. How much did it rain in the second half of the month?
Answer: 1/5
Step-by-step explanation:
Let the amount of rainfall in the second half of the month be represented by x.
From the information given in the question, the equation formed will be:
3/10 + x = 1/2
x = 1/2 - 3/10
x = 5/10 - 3/10
x = 2/10
x = 1/5
Therefore, the answer is 1/5

Sheila is flying a kite with a string that makes a 59-degree angle with
the sand. If the height of the kite above the ground is 97 feet, how
long is the string? (Please use the exact ratio to calculate the missing
side and round your answer to the nearest hundredth.)
Answer:
113.16 feet
Step-by-step explanation:
Representing the given details appropriately with a right angle triangle. Let the length of the string for the kite be represented by x. Applying required trigonometric function, we have:
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Sin [tex]59^{o}[/tex] = [tex]\frac{97}{x}[/tex]
x = [tex]\frac{97}{Sin59^{o} }[/tex]
= [tex]\frac{97}{0.8572}[/tex]
= 113.1591
x = 113.16 feet
Thus, the string for the kite is 113.16 feet long.
Are 12/7 and 36/21 proportional
Answer:
Step-by-step explanation:
Cross multiply:
12 * 21 = 7 * 36
Simplifying
12 * 21 = 7 * 36
Multiply 12 * 21
252 = 7 * 36
Multiply 7 * 36
252 = 252
Add '-252' to each side of the equation.
252 + -252 = 252 + -252
Combine like terms: 252 + -252 = 0
0 = 252 + -252
Combine like terms: 252 + -252 = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
(hope this helps can i plz have brainlist :D hehe)
From the calculations below, 12/7 and 36/21 are proportional, therefore, the statement is true.
The first fraction given is 12/7.
The second fraction given is 36/21.
In order to check, we can multiply both the numerator and the denominator by 3. This will be;
= (12 × 3) / (7 × 3)
= 36 / 21
Therefore, it has been solved that 12/7 and 36/21 are proportional.

How do I round 31732.441804 to the nearest dollar?
Answer and Step-by-step explanation:
To round to the nearest dollar, you are essentially rounding to the nearest whole number.
This involves looking at the tenths place.
31732.441804
The bolded 4 is in the tenths place (after the decimal), and determines if the number to the left of it rounds up or stay the same.
Since 4 is not greater than or equal to 5, it makes the number stay 2.
So, we get the answer to be $31732.
