A flute case is shaped like a rectangular prism. The case is 5 inches tall, 3 inches wide, and has a volume of 255 cubic inches. What is th elength of the flute case?
Answer:
The length of the case is 17 inches.
Step-by-step explanation:
A flute case is shaped like a rectangular prism with dimensions:
height = 5 inches;
width = 3 inches;
length = x inches.
The volume of the case is 255 cubic inches.
Use formula for the volume of the rectangular prism:
Thus,
The length of the case is 17 inches.

m21 = m25
mz3 = M24
m21 + m24 = 180°
m26 = 75°
m22 + m25 = 180°
All the correct statements that are true,
⇒ m ∠1 = m ∠ 5
⇒ m ∠2 + m ∠5 = 180°
⇒ m ∠6 = 75°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
In the figure, lines a and b are parallel.
Now, By definition of alternate and corresponding angles, we get;
⇒ m ∠1 = m ∠ 5
⇒ m ∠6 = 75°
And, By definition of linear pair of parallel lines,
⇒ m ∠2 + m ∠5 = 180°
Thus, All the correct statements that are true,
⇒ m ∠1 = m ∠ 5
⇒ m ∠2 + m ∠5 = 180°
⇒ m ∠6 = 75°

dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year. how much will he earn in 4 years?
Answer:
= $655.20
Step-by-step explanation:
Simple Interest =( Principal * rate * time)/100
=( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.
= 65520/100
= $655.20
Dexter will earn $655.2.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
Formula to calculate the simple interest is;
S.I. = P x T x R / 100 ,
Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.
Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.
P = $6300
R = 2.60% and T = 4 years
Then by the formula;
6300 x 2.6 x 4 /100
= $655.2
Therefore, Dexter will earn $655.2.

Answer:
25. y=2x+1
26. $13
Step-by-step explanation:
25. 2x is the cost each day or the x, and the 1 is the initial fee, I found this because it said one day costs $3 and if I know that one days fee is $2 then I know that the y intercept or the price it starts at also known as a fee is $1. This is also backed up in the 4 day statement saying that 4 days is 9 dollars. I can do 9-1 to take away the fee and 8/2=4 so it is correct.
26. Since I already have the equation I can just plug in the vales and solve. y=2x+1, x=2 or the daily cost so 12+ (the fee) 12+1=13 so $13.
good luck, and have a great day. :)

Write and solve an equation that can be used to find x, in the figure below:
Answer: x=40
Step-by-step explanation:
so you would add the two angles you already know.
30+63=93
The sum of the angles of a triangle is always 180°. Knowing this, you can do
180-93=87
so you know the third angle is 87°
plug this into the equation: 2x+7
2x+7=87
subtract both sides by 7
2x=80
divide by two
x=40

Sam drew a rectangle measuring 9 feet in length by 15 feet in width. If she wants to make a similar rectangle measuring 27 feet in length, what should the width be?
Answer:
45
Step-by-step explanation:
If sam made a rectangle 9 feet in length and 15 in width. And we already know the next rectangle is 27 feet we can divide it by 9.
27/9=3
Now that we know its 3x the normal size we can grab the 15 and multiply it by 3.
