Ryan is trying to determine whether 2.7x – 5.9 is equivalent to 2.8x – 5.9. To test this, he substitutes 0 for x into both expressions. Explain why this will not give him the correct answer. send help ty
Answer:
Nggak tahu bahasa inggriis aku bang
Answer:
The coefficients of x are different in the expressions, but the constant values are the same. Zero times any value is zero, so both expressions will be equal to -5.9. If Ryan tried any other number, he would see that the expressions are not equivalent.

A glass paperweight is shown below.
The paperweight is a hemisphere with diameter 9cm..
Find the surface area of the paperweight.
Answer:
[tex]A=190.75\ cm^2[/tex]
Step-by-step explanation:
The diameter of a hemisphere, d = 9 cm
Radius, r = 4.5 cm
We need to find the surface area of the paperweight. The formula for the surface area of a hemisphere is given by :
[tex]A=3\pi r^2\\\\A=3\times 3.14\times (4.5)^2\\\\A=190.75\ cm^2[/tex]
So, the surface area of the paperweight is [tex]190.75\ cm^2[/tex].

Kamal is buying supplies for a science lab. He needs a piece
of wire 7 feet long. He finds wire for sale at a store that lists the
lengths in inches. How many inches of wire should Kamal buy?
A 19 in.
B
72 in.
74 in.
84 in.
Answer:
kamal needs to buy 84 in of wire.
Step-by-step explanation:
multiply the length value by 12:
if he wants 7 feet, and the store only sells it in inches, then we know what a foot is twelve inches so 12x7=84.
hope this helped! :D <3

A construction worker dropped a hammer while building the Grand Canyon skywalk, 4000 feet above the Colorado River. Use the formula, t = h 4 , to find how many seconds it took for the hammer to reach the river. Round your answer to the nearest second.
Answer: Hammer reaches river after 15.8 seconds.
Step-by-step explanation:
Use formula: t = square root of h divided by 4. In this problem h = 4,000.
Therefore,
T = square root of 4,000 divided by 4.
T = 15.8 seconds

Is 1/6 greater or 1/24
Answer:
yes
Step-by-step explanation:
Answer: 1/6 is greater than 1/24
=========================================================
Explanation:
Let's assume that 1/6 is equal to 1/24 for now. We'll see later this is false.
1/6 = 1/24
1*24 = 6*1 .... cross multiply
24 = 6
The last equation is false, so the first equation is false.
To fix things, we need to replace every equal sign with a greater than sign like so
1/6 > 1/24
1*24 > 6*1
24 > 6
Now each of those three statements are true, since the last statement is true. This shows that 1/6 is greater than 1/24.
----------------
We can take another approach to use the calculator to see that
1/6 = 0.167 approximately
1/24 = 0.042 approximately
We can see that 0.167 is the larger decimal, so 1/6 is the larger fraction.
If you want, you can move the decimal point over 3 spots to the right for each decimal number. So that would mean 0.167 becomes 167, and 0.042 becomes 42. Then it becomes more clear that 167 is the larger value, helping confirm that 0.167 is the larger decimal.
4x+3(2x-1)-4x i need help
Answer:
x=0.5
Step-by-step explanation:
Simplifying
4x + -3(2x + -1) + -4x = 0
Reorder the terms:
4x + -3(-1 + 2x) + -4x = 0
4x + (-1 * -3 + 2x * -3) + -4x = 0
4x + (3 + -6x) + -4x = 0
Reorder the terms:
3 + 4x + -6x + -4x = 0
Combine like terms: 4x + -6x = -2x
3 + -2x + -4x = 0
Combine like terms: -2x + -4x = -6x
3 + -6x = 0
Solving
3 + -6x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -6x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -6x = 0 + -3
-6x = 0 + -3
Combine like terms: 0 + -3 = -3
-6x = -3
Divide each side by '-6'.
x = 0.5
Simplifying
x = 0.5
Find the area of each.

Help plz
Answer:
The area would be 153.86
Step-by-step explanation:
Since the diameter is 14, the radius would be 7.
The area is pi times the radius squared.
7 squared is 49.
If your using 3.14 for pi, then its 3.14 times 49.
That gives you 153.86.

Answer: 3
Step-by-step explanation:
A term is a group of numbers and variables.
In your expression, there are 3 term: 3k, 10, and 5n^3A coefficient is just the number attached to the variable.
In the term 3k, the first one in your expression, the 3 is the coefficient because it is being multiplied by an unknown, k. There is also another term with a variable in your expression: 5n^3. 5 would be the coefficient because it is being multiplied by an unknown, n, multiplied by itself three timesA constant is just a number.
In your expression, 10 is a constant because it doesn't have a variable, so no matter what the other variables are, that term will always stay 10Hope this helps :)
Find the value of x that satisfies 1+3(1+3(1+3(1+x))) = 13.
Answer:
The conclusion of the Mean Value Theorem says that there is a number
c
in the interval
(
1
,
3
)
such that:
f
'
(
c
)
=
f
(
3
)
−
f
(
1
)
3
−
1
To find (or try to find)
c
, set up this equation and solve for
c
.
If there's more than one
c
make sure you get the one (or more) in the interval
(
1
,
3
)
.
For
f
(
x
)
−
−
2
x
2
−
x
+

, we have
f
(

=
−

, and
f
(

)
=
−

−
3
+

=
−
19
Also,
f
'
(
x
)
=
−

x
−
1
.
So the
c
we're looking for satisfies:
f
'
(

=
−

c

=
f
(

f

=

−

3

So we need

c
−
1
=
−
9
. And
c
=
2
.
Note:
I hope you've been told that actually finding the value of
c
is not a part of the Mean Value Theorem.
The additional question"find the value of
c
" is intended as a review of your ability to solve equations. For most functions, you will not be able to find the
c
that the MVT guarantees us is there..
