Answer:
0.2821 gal
Step-by-step explanation:
Since this is a direct and proportional relationship, we know that the ratio for 2.539 gal of water to 9 hours is the same as the ratio from the water in the pool after 1 hour to 1 hour. Therefore, we can simplify 2.539:9 into 0.2821111... I’m not sure what value you must round to, so I’ll assume it is to the nearest thousandth. Hence, our answer is 0.2821 gal.
I hope this helps! :)

A person breathes 2.5 x 10^-4 in about cubic meters of air per second. How long does it take to breathe in 2.5 cubic meters of air?
Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes [tex]2.5\times 10^{-4}[/tex] in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec = [tex]2.5\times 10^{-4}[/tex] m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.
[tex]x=\dfrac{2.5}{2.5\times 10^{-4}}\\\\x=10^4\ s[/tex]
Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.

how can you use the pythagreom therem to solve real-world problem
Answer:
This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope.
Answer:
Architecture, Engineering, Astronomy, etc.
Step-by-step explanation:
Engineers use the Pythagorean Theorem by knowing the height of the roof and the length for it to cover, and it will result in the diagonal length of the roof's slope. Architects use the Pythagorean Theorem to calculate the heights of buildings and the lengths of walls. Astronomers sometimes use the theorem to calculate the paths of spacecraft, including rockets and satellites.

A process is making a part that weighs 0.75 oz on average with a standard deviation of 0.05 oz. The upper and lower specifications for the part are 1 oz and 0.5 oz, respectively. Which measure should be used to see how well the process meets its specification limits
Answer:
The correct answer is the process capability index
Step-by-step explanation:
According to the given scenario, the process capability index is the index where it determines the capability or the ability of the process with respect to generating the output or results within the given limits
Therefore as per the given scenario, it represents the process capability index as it fits to the current situation given in the question.
Therefore The correct answer is the process capability index

The mixed fraction number 2 ⁷/₈ is greater than the mixed fraction number 2 ¹/₂.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The mixed fraction numbers are given below.
2 ⁷/₈ and 2 ¹/₂
Convert the mixed fraction number into a decimal number. Then we have
2 ⁷/₈ = 2 + 7/8 = 2 + 0.875 = 2.875
2 ¹/₂ = 2 + 1/2 = 2 + 0.50 = 2.50

Joel's Taxi Service charges a flat rate of $15 plus $0.10 for each mile. Write an equation in function notation and find out how much it would cost to travel 25 miles.
Answer: It would cost $17.5 travel 25 miles.
Step-by-step explanation:
Given: Flat rate = $15
Charge per mile = $0.10
Total cost = Flat rate + (Charge per mile) (Number of miles)
Let x= Number of miles traveled.
So Total cost = 15 +0.10x
Put x= 25 miles
Total cost = 15 +0.10(25)
= 15+2.5 = $17.5
Hence, it would cost $17.5 travel 25 miles.
Cut out the shapes of NETS of Cube, Cuboid and Cylinder as per the dimensions given below and find its Total Surface Area and Lateral Surface Area Dimensions of Cube = 5cm x 5cm x 5cm Dimensions of Cuboid = Length=10cm, Breadth=5cm, Height = 4cm Dimensions of Cylinder= Diameter 7cm and height 10cm
Answer:
a. i. 150 cm³ ii. 150 cm³
b. i. 220 cm³ ii. 120 cm³
c. i. 297 cm² ii. 220 cm²
Step-by-step explanation:
a. For the cube
Dimensions of Cube = 5cm x 5cm x 5cm
Length of side = 5 cm
i. Total surface area A = 6L² where L = length of side = 5 cm
So, A = 6 × (5 cm)²
= 6 × 25 cm³
= 150 cm³
ii. Lateral surface area A' = 4L²
= 4 × (5cm)²
= 4 × 25 cm²
= 100 cm²
b. For the cuboid
Dimensions of Cuboid = Length, l = 10cm, Breadth, b = 5cm, Height, h = 4cm
i. Total surface area A = 2(lb + lh + hb)
= 2(10 cm × 5 cm + 10 cm × 4 cm + 4 cm × 5 cm)
= 2(50 cm² + 40 cm² + 20 cm²)
= 2(110 cm²)
= 220 cm²
ii. Lateral surface area A' = 2(lh + hb)
= 2h(l + b)
= 2 × 4 cm (10 cm + 5 cm)
= 8 cm × 15 cm
= 120 cm²
c. For the cylinder
Dimensions of Cylinder = Diameter, d = 7cm and height, h = 10cm
i. Total surface area, A = 2πr(r + h) where r = radius = d/2
A = πd(d/2 + h)
= 22/7 × 7 cm(7 cm/2 + 10 cm)
= 22cm(3.5 cm + 10 cm)
= 22cm(13.5 cm)
= 297 cm²
ii. Lateral surface area A = 2πrh
= πdh
= 22/7 × 7 cm × 10 cm
= 22 cm × 10 cm
= 220 cm²

What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.
We have been given number line going from negative 4 to positive 4.
Negative 2.4, negative 1.5, negative 2 and one-fourth, negative 3, negative 1 and one-eighth
For this we need to remember the number line, we have that that:
-3 <-2.4 < -2 < 1/4 <-1.5 < -1 < -1 1/8< 0
We go from the big negative numbers, to the small negative numbers, the zero, the small positive numbers, the big positive numbers.
Therefore, the numbers from least to greast the correct options are:
-3, -2.4, -2 1/4, -1.5, -1 1/8

Compute the value of the discriminant and give the number of real solutions of the quadratic equation.
−4x^2 + 6x - 1=0
Answer:
Value of discriminant is 20
Step-by-step explanation:
Formula of discriminant is:
[tex]D=b^2-4ac[/tex]
so our equation is
[tex]-4x^2+6x-1=0[/tex]
where a = -4, b = 6 , c = -1
so our discriminant becomes,
[tex]D=b^2-4ac\\D=(6)^2-4(-4)(-1)\\D=36-16\\D=20[/tex]
Since the discriminant is positive we have two distinct real number solutions or two distinct roots, and to solve the we just use the quadratic formula and get the two different values of x.
[tex]x_1=0.191\\x_2=1.309[/tex]
