What is the volume of this cone? Use 3.14 for pi and round your answer to the nearest tenth.
In your answer, give the volume of the cone rounded to the nearest tenth, and then explain how u calculated it
Answer:
33.5 in^3
Step-by-step explanation:
The formula for a cone is (pi)(r^2)(h/3)
Since we need to use 3.14 for pi, we will plug in 3.14 for pi. It should look like this: (3.14)(r^2)(h/3)
The radius is 2 and the height is 8. Plug in the numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.66...)
Multiply:
(12.56)(2.66...) -> 39.4933...
Finally, 39.4933... is rounded to the tenths place:
39.5

A loan has an APR of 8%. The maximum that Steve can pay back monthly on a loan is $129.60. He wants the loan for 1 year.
Answer:
$1,679.62
Step-by-step explanation:
129.60*12=$1,555.20
You then do 1,555.2*.08, and get:124.416
You then add the 2 together to find the amount needed to be paid back.
What is the following sum?

[tex]12b^2\sqrt[3]{2a}[/tex]
In word form, this is 12 b squared (RootIndex 3 StartRoot 2 a EndRoot
Or you could say 12b^2 times the cube root of 2a

The idea here is that we break the cube roots into smaller pieces, so we pull out perfect cubes when factoring.
The sum of the expression is 12 b squared (Root Index 6 Start Root 2 a End Root) or 12b²∛(2a).
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
We have the expression,
3 b squared (Root Index 3 Start Root 54 a End Root) + 3 (Root Index 3 Start Root 2 a b Superscript 6 Baseline End Root).
In numerical form,
3b²∛(54a) + 3∛(2ab⁶)
To find the sum of the above expression:
we simplify the expression,
3b²∛(54a) + 3∛(2ab⁶)
= 3b²∛3³(2a) + 3∛(2a)(b²)³
= 9b²∛(2a) + 3b²∛(2a)
= 12b²∛(2a)
Therefore, the sum is 12b²∛(2a).

What is the length of AC?
Answer:
Length of AC = 12units.
Step-by-step explanation:
[tex]\sf\large{\star Given:-}[/tex]
Hypotenuse of the triangle = [tex]\sf\pink{10\:units.}[/tex]Height of the triangle = [tex]\sf\pink{8 \: units.}[/tex][tex]\sf\large{\star To\: Find:-}[/tex]
[tex]\rightarrow[/tex] Base of the triangle.
[tex]\sf\large{\star Solution:-}[/tex]
[tex]\rightarrow[/tex]As we know that,
Pythagoras Theorem:
[tex]\sf\blue{Hypotenuse^2\:=\: Height^2+Base^2}[/tex]
So, In triangle ABD by putting the value of hypotenuse and height in this formula we get,
[tex]\rightarrow[/tex][tex]\sf{10^2\:=\: 8^2 + Base^2}[/tex]
[tex]\rightarrow[/tex][tex]\sf{100\:=\: 64 + Base^2}[/tex]
[tex]\rightarrow[/tex][tex]\sf{100-64\:=\: Base^2}[/tex]
[tex]\rightarrow[/tex][tex]\sf{36\:=\: Base^2}[/tex]
[tex]\rightarrow[/tex][tex]\sf{\sqrt{36}\:=\: Base}[/tex]
[tex]\rightarrow[/tex][tex]\sf{6\:=\: Base}[/tex]
Since, it is given that BD is the perpendicular bisector of AC so length of AC will be doubled.
Therefore, length of AC of the given triangle = [tex]\sf\purple{12units.}[/tex]
Let f(t) ANSWER: 1+ = t² - 1 t+3 Find f'(1)
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3

How many cubes with side length of 4cm can be packed into a wooden box measuring 32cm by 16cm by 8cm
PLEASE HELP Me!!
Answer:
64 cubes
Step-by-step explanation:
The volume of wooden box,
→ x = l × b × h
→ x = 32 × 16 × 8
→ [x = 4096 cm³]
The volume of a cube,
→ y = side³
→ y = 4 × 4 × 4
→ [ y = 64 cm³]
Now we have to,
find how many cubes can be packed inside the wooden box.
→ x ÷ y
→ 4096 ÷ 64
→ 64 cubes
Hence, the solution is 64 cubes.

Answer: -1 [tex]\frac{1}{5}[/tex], -1, 0.25, [tex]\frac{1}{2}[/tex] , 0.75
Step-by-step explanation:
I will turn all of these numbers into numbers that are not fractions since most of the numbers are already this way.
0.75 -> 0.75
-1 -> -1
[tex]\frac{1}{2}[/tex] -> 0.5
-1 [tex]\frac{1}{5}[/tex] -> -1.2
0.25 -> 0.25
First of all, the negative numbers are smaller than the positive numbers. Then, we can order them least to greatest by number.
-1.2, -1, 0.25, 0.5, 0.75
Putting the numbers into what they were originally given as gives us this:
-1 [tex]\frac{1}{5}[/tex], -1, 0.25, [tex]\frac{1}{2}[/tex] , 0.75
The answer is the last option, -1 [tex]\frac{1}{5}[/tex], -1, 0.25, [tex]\frac{1}{2}[/tex] , 0.75.

A college graduate invests $3,000 into an account that earns 6% annual interest compounded monthly. What is the value (in dollars) of
the investment after 5 years? (Round your answer to the nearest cent.)
Answer:
$4,014.68
Step-by-step explanation:
A = $4,014.68
A = P + I where
P (principal) = $3,000.00
I (interest) = $1,014.68
First, convert R as a percent to r as a decimal
r = R/100
r = 6/100
r = 0.06 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 3,000.00(1 + 0.06/1)^(1)(5)
A = 3,000.00(1 + 0.06)^(5)
A = $4,014.68
The chart below describes the speed of four runners. Which runner is the fastest?
Runner A ran 1 mile in 8 minutes
Runner B ran 2 miles in 10 minutes
Runner C ran 3 miles in 20 minutes
Runner D ran 5 miles in 30 minutes
Answer:
Runner B
Step-by-step explanation:
speed = distance ÷ time
Runner A: 1 ÷ 8 = 0.125m/ms
Runner B: 2 ÷ 10 = 0.2m/ms
Runner C: 3 ÷ 20 = 0.15m/ms
Runner D: 5 ÷ 30 = 0.17m/ms
Runner B has the highest speed so he is the fastest runner.

What is the circumference of a circle with a radius of 11 cm? (Use = 3.14.)
A.
103.62 cm
B.
69.08 cm
C.
34.54 cm
D.
379.94 cm
First, we need to follow the circumference of a circle formula, which is [tex]C = 2 \pi r[/tex]. Since we know the radius, we can plug 11 for the radius and 3.14 for pi.
The equation should now look like this: [tex]C = 2 * 3.14 *11[/tex]. Then, we multiply. After solving, the circumference of the circle is 69.08 centimeters.
if z 2 square equal 49 what are the solutions
z = 7, z = -7
Calculations ↓z² = 49
Take the square root of both sides to find what z equals
z = 7
Is that the only solution? Is 7 the only number that can be multiplied by itself and have a result of 49? No, there's another number. This number is -7.
So the solutions are ↓7, -7

Answer:
WX = 20
FG = 10
Step-by-step explanation:
If EFGHI ~ VUTXW
then:
EF~VUFG~UTGH~TXHI~XWIE~WVThe only pair of sides that both have measures is EF and VU
EF = 8
VU = 16
VU/EF = 16/8 = 2
Therefore, VUTXW is enlargement of EFGHI by a scale factor of 2.
As HI = 10
⇒ WX = 10 × 2 = 20
As UT = 20
⇒ FG = 20 ÷ 2 = 10
