What is the volume of a cylinder, in cubic centimeters, with a height of 16 centimeters and a base diameter of 4 centimeters? Round to the nearest tenths place.
Answer:
200 cubic centimeter
Step-by-step explanation:
Answer:
201.1 cc
Step-by-step explanation:
r = d/2
v = πr^2 h
---------------------
r = 4/2
r = 2
v = π * (2^2) * 16
v = 3.14159 * 4 * 16
v = 201.06176
Rounded
v = 201.1 cc
--------------------
note:
if 3.14 is used for π
v = 200.96
which rounds to
v =201.0
Tyrod needs at least $820 to buy the computer he wants. He has already saved $330. He earns $50 per lawn that he cuts. What is the least number of lawns that he can cut and buy the computer? Which inequality represents the problem?
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The equation representing the given statement is ~
[tex]50x + 330 \geqslant 820[/tex]The least number of lawns that he can cut and buy the computer is 10 lawns ~
[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]
Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
total number of lawns cut × $5050xtotal savings is equal to ~
330 + 50xhence,
[tex]50x + 330 \geqslant 820[/tex]by solving for " x (number of lawns cut) " we get ~
[tex]50x \geqslant 820 - 330[/tex][tex]50x \geqslant 490[/tex][tex]x \geqslant 490 \div 50[/tex][tex]x \geqslant 9.8[/tex]Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is

Step-by-step explanation:
Solve the quadratic equation shown below using the completing the square method. x2+6x=−17 Use the drop-down menus to choose the words or numbers to correctly complete each statement below. To solve the equation by completing the square, a first step is to add 17 to both sides of the equation. The resulting equation will be a perfect square trinomial on the left side, which can be factored into the quantity x + 3 squared, and the right side will have a value of . A next step is to take the square root of both sides to isolate the variable . will be a complex number since
Answer:
7
Step-by-step explanation:
because you just take the quadratic number and divide it by x2 and you get 7!!!
Answer:
x = - 3 ± 2i[tex]\sqrt{2}[/tex]
Step-by-step explanation:
x² + 6x = - 17
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(3)x + 9 = - 17 + 9
(x + 3)² = - 8 ( take square root of both sides )
x + 3 = ± [tex]\sqrt{-8}[/tex] = ± 2i[tex]\sqrt{2}[/tex] ( subtract 3 from both sides )
x = - 3 ± 2i[tex]\sqrt{2}[/tex]

The regular price of a code is $32 it is on sale at 25% off the sales tax is 6.5% what is the final cost of code
Answer:
$25.56
Step-by-step explanation:
first find the discount
32 • 0.25 = 8
32 - 8= 24
find the tax
24 • 0.065 = 1.56
24 +1.56 = 25.56
so the final price is $ 25.56
Answer:
25.56
Step-by-step explanation:
25% of 32= 8
32-8= 24
6.5% of 24= 1.56
24+1.56= 25.56

The University of Washington Huskies tried throwing one of the longest Hail Marys in history—about 73 yards! For this pass, the ball's height over time was modeled by the function h(t) = -16t2 + 64t + 6, where was the height in feet and was the time in seconds. a) How long does it take for the football to reach its maximum height? b) What is its maximum height? c) How long will the football be in the air? It takes a good college football player about 8 seconds to run 73 yards. If the quarterback waited 4 seconds after the snap, does the receiver have a chance of catching the ball?
Answer:
See belowStep-by-step explanation:
Given function:
h(t) = -16t² + 64t + 6a)
The maximum height is the vertex. The x-coordinate of the vertex is -b/2a:
t = - 64/2*(-16) = 2It takes 2 seconds
b)
Maximum height is at vertex:
h(2) = -16(2²) + 64(2) + 6 = 70 ydc)
The ball is in the air between zero's of the equation or approximately double the time it reaches the vertex:
2*2 = 4 secondsThe receiver doesn't have a chance to catch the ball, since the ball is only 4 seconds in the air.
Steel is a mixture of iron, carbon, and other elements. The table shows the number of parts each element in two different-sized samples of steel.
A table with the composition of two samples is shown. Sample one is ninety parts iron, three parts carbon, and seven parts other elements. Sample two is forty-five parts iron, one and a half parts carbon, and three and a half parts other elements.
Question 1
Part A
What is the unit rate of parts iron to parts carbon?
Enter the correct answer in the box.
parts iron per part carbo
Answer:
Step-by-step explanation:
Sample One, Parts and % Sample Two, Parts and %
Fe 90 (90%) 45 (90%)
C 3 (3%) 1.5 (3%)
Other 7 (7%) 3.5 (7%)
100 parts 50 parts
Parts Fe/Parts Carbon = 90/3 or 30/1 in both cases [45/1.5 = 30/1]

3x4y=-2
9x-10y=38
elimnation method
Answer:
x = 2
y = -2
Step-by-step explanation:
N.B. Assuming the first equation is actually 3x + 4y = -2
The elimination method is an incredibly useful tool used to save large amounts of time when working with small systems of equations.
First, set one variable in the top equation to have an equal coefficient as that same variable in the bottom equation.
3(3x + 4y) = 3(-2)
Then, you are left with this. Simply subtract the equations.
9x + 12y = -6
9x - 10y = 38
0 + 22y = -44
Then, simply solve
y = -2
9x + 20 = 38
9x = 18
x = 2

Answer:
9 should be the greatest common factor. (I think) because 3b² =9b
12b⁴=48b
Answer:
3*(4b^4-b^2)
Step-by-step explanation:
you are looking for the greatest number who can be divided by the number(3) and the other number(12) , the greates common factor here is 3
and then take out the 3
so 3*(4b^4-b^2)
Jennifer installs solar panels. Today it takes her 8
hours to install 2 solar panels. She plans to install
solar panels for 40 hours next week.
10 solar panels according to me is the answer
Answer: 10
Step-by-step explanation:
40 hours/8 hours = 5 hours
5 hours *2 solar panels = 10 solar panels
Since it takes her 8 hours to install 2 solar panels, we need to multiply 5 with 2.
What is the value of a if 5a = 1/125
(It’s not 1/625)
Please answer!!
Answer:
a = -3.
Step-by-step explanation:
5^a = 1/125
5^3 = 125
so 5^-3 = 1/125
Answer:
a = -3
Step-by-step explanation:
5^a = 1/125
Rewriting 1/125 as 1/5^3 = 5^-3
5^a = 5^-3
a = -3
