A club swimming pool is 34 ft wide and 48 ft long. The club members want an exposed aggregate border in a strip of uniform width around the pool. They have enough material for 344 ft2. How wide can the strip be?
Answer:
29
he area of the pool is 34 ft * 48 ft = <<34*48=1632>>1632 ft2.
Thus, the total area of the pool and the border strip is 1632 ft2 + 344 ft2 = <<1632+344=1976>>1976 ft2.
Hence, the border strip is 1976 ft2/34 ft = <<1976/34=58>>58 ft long.
Therefore, the border strip can be 58 ft/2 = <<58/2=29>>29 ft wide. Answer: {29}.

A. Q1 = 1.6; Q2 = 2.5; Q3 = 2.92
B. Q1 = 1.7; Q2 = 2.5; Q3 = 3
C. Q1 = 1.7; Q2 = 2.5; Q3 = 2.9
D. Q1 = 1.6; Q2 = 2.5; Q3 = 2.95
Answer:
To find the value of the quartiles, we need to first find the median of the data set. The median is the middle value of the data set, or the value that separates the lower half of the data from the upper half. In this data set, the median is 2.5, as it is the middle value when the data is arranged in ascending order.
Once we have the median, we can find the first and third quartiles. The first quartile, also known as Q1, is the median of the lower half of the data set, and the third quartile, also known as Q3, is the median of the upper half of the data set. In this data set, the lower half of the data is {1.3, 1.5, 1.7, 2, 2.5}, and the upper half of the data is {2.7, 2.9, 3, 3.1}. The median of the lower half is 1.7, and the median of the upper half is 2.9.
Therefore, the value of the quartiles is Q1 = 1.7, Q2 = 2.5, and Q3 = 2.9.

HELP PLEASE!!!!!!!! APPLY THE DISTRIBUTIVE PROPERTY USING THE GCF TO WRITE EQUIVALENT EXPRESSION. 0.3x - 2.7 HELP PLEASE!!!!!
Answer:
To apply the distributive property using the greatest common factor (GCF) to write an equivalent expression for 0.3x - 2.7, we need to find the GCF of the coefficients of the terms in the expression. In this case, the GCF is 0.3, so we can write the expression as 0.3(x - 9). This is an equivalent expression to 0.3x - 2.7, because multiplying 0.3 by the difference of x and 9 produces the same result as subtracting 2.7 from 0.3x.

identify the measure of angle x. i need answer asap
After solving the angles, the measure of angle x is 145°.
What are angles?When two straight lines or rays intersect at a single endpoint, an angle is created.
The vertex of an angle is the location where two points come together.
The Latin word "angulus," which means "corner," is where the term "angle" originates.
The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.
A geometrical shape called an angle is created by connecting two rays at their termini.
In most cases, an angle is expressed in degrees.
(Refer to the image attached below)
We can see that ∠ABC is a straight angle.
∠ABC = ∠ABD + ∠DBC where ∠ABD is x.
Now, solve for x as follows:
∠ABD + ∠DBC = ∠ABC
x + 35 = 180
x = 180 - 35
x = 145°
Therefore, after solving the angles, the measure of angle x is 145°.
