Answer:
Cone volume formula
To calculate its volume you need to multiply the base area (area of a circle: π * r²) by height and by 1/3: volume = (1/3) * π * r² * h
Step-by-step explanation:
The diagram below shows a circular pizza with a diameter of 12 inches. The pizza is in a square box with side lengths of 14 inches. In square inches, how much of the box is empty?
Use π = 3.14 and round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
Area of box = 14^2 = 196 in^2
Radius r of pizza = 12/2 = 6
Area of pizza = πr² = 36π ≈ 113.04 in^2

The data above can be modeled by the function f(x) = 0.0425x^2 + 0.07381x - 0.49107 . Using this equation, predict the skid distance for a car that is driving 50 mph.
Answer:
f(50) = 109.44943 feet
Step-by-step explanation:
Modeling
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
[tex]f(x) = 0.0425x^2 + 0.07381x - 0.49107[/tex]
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
[tex]f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107[/tex]
[tex]f(50) = 106.25 + 3.6905 - 0.49107[/tex]
f(50) = 109.44943 feet

what is the factored form of -40+2×^2-2x
Answer:
2(x - 5)(x + 4)
Step-by-step explanation:
Given
- 40 + 2x² - 2x , that is
2x² - 2x - 40 ← factor out 2 from each term
= 2(x² - x - 20) ← factorise the quadratic
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)
The factors are - 5 and + 4 , since
- 5 × 4 = - 20 and - 5 + 4 = - 1 , then
x² - x - 20 = (x - 5)(x + 4) and
2x² - 2x - 40 = 2(x - 5)(x + 4) ← in factored form

Simone wrote that 2 + 5.8 = 6.
Use the drop-down menus to explain why 6 is incorrect.
Answer:
7.8
0.2
Step-by-step explanation:
2 is in the ones place, to get to six you need the value of 2 in the tenths place (0.2)
2+5.8 is 7.8 (add the ones places together to get 7)
0.2+5.8=6 (add in the tenths place)
What is the implication, hypothesis and conclusion in this statement all engineers are resourceful.
Answer:
The majority of theorems in mathematics take the form of compound statements. These statements are called conditional and biconditional statements.
The conditional statement from the sentence above is:
If x is an engineer then x is resourceful.
Put in a mathematical form we can refer to the Implication as:
If Xe then R. Or
Xe implies R. Or
Xe if R.
The Hypothesis is stated as
Xe ⇒ R
The statement Xe in an implication Xe ⇒ R is called its hypothesis, premise, or antecedent, and R the conclusion or consequence.
Implications are critical in expressing a logical argument. If an implication is found to be true, then the consequences must be as well when the hypothesis satisfied. This is why is also referred to as a conditional statement.

please help my friend, he's struggling on math
Answer:
question 1 = 37 covers , 535 dollars
question 2 = 32 covers , 460 dollars
Expression = 69 covers , 995 dollars
Step-by-step explanation:
You would take the number of covers and multiply it by 15 because 15 dollars is how much they sold each cover for.
and then for the expression wasnt sure what to do but from what i could see you added up the totals.
Hope this helped him :)
also tell me what his snap is BAHA okay lemme stop.

Given triangle ABC and a point D on the side AC. Suppose AB=6, BC=8, AC=9, and AD=4. Find BD
Answer:
BD = 5 1/3
Step-by-step explanation:
Triangle ABD and ACB are similar with angle A = angle A, angle ABD = ACB. Similar by AA. AB:AC = 6:9, AD:AB = 4:6. This means that the ratio of triangle ABD : ACB is 1 : 1.5. Because of this, since BD corresponds to BC, then BD : 8 = 1 : 1.5, and BD = 8 divided by 1.5, so BD = 5 1/3
Hope this helped :)

Solve the equation for b 4a + 6c – 2b = 12 .
Answer:
b=2a+3c−6
Step-by-step explanation:
Let's solve for b.
4a+6c−2b=12
Step 1: Add -4a to both sides.
4a−2b+6c+−4a=12+−4a
−2b+6c=−4a+12
Step 2: Add -6c to both sides.
−2b+6c+−6c=−4a+12+−6c
−2b=−4a−6c+12
Step 3: Divide both sides by -2.
−2b
−2
=
−4a−6c+12
−2
b=2a+3c−6
Answer:
b=2a+3c−6

The wheels on Kevin’s bike have a diameter of about 3 feet. How far does the bike travel in 12 complete rotations? (Use 3.14 to represent pi)
Answer:
113.04 feetStep-by-step explanation:
Use circumference formula to find one rotation:
C = 2πr = πdC = 3.14*3= 9.42 feetFull travel of 12 rotations:
12*9.42 = 113.04 feetUse circumference formula to find one rotation:
C = 2πr = πd
C = 3.14*3= 9.42 feet
Full travel of 12 rotations:
12*9.42 = 113.04 feet Ans.

and she already had $100 saved, how many hours does she need to work to
make enough for her trip to DR?
Answer:
24 hours
Step-by-step explanation:
first subtract 100 from 460 to get 360, then divide 360 by 15 which equals 24.
