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.
Answers
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.
how can you use the pythagreom therem to solve real-world problem
Answers
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 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?
Answers
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.

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
Answers
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
convert: ___minutes= 7/10 hour

Compute the value of the discriminant and give the number of real solutions of the quadratic equation.
−4x^2 + 6x - 1=0
Answers
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]
