Step-by-step explanation:
3890 - 3200
=690
(690÷3200) x 100%
=21.56%
Answer:
21.56/ 21.6/ 22 (depending on the decimal places you want)
Step-by-step explanation:
Current figure- original figure / Original figure * 100
3890-3200 = 690
690/3200 = 0.215625
0.215625 * 100 = 21.56 / 21.6 / 22
* means multiply

If f(1)=10 and f(n)=-2f(n-1) then find the value of f(5)
9514 1404 393
Answer:
f(5) = 160
Step-by-step explanation:
The first several terms of the sequence are ...
10, -20, 40, -80, 160, -320, 640, ...
Each term is -2 times the previous term.
f(5) = 160
For the function f(x) = -12x^2 + 6x - 8 find the equation of the tangent line at x= -1

Answer to the question
Answer:
x = 48.
Step-by-step explanation:
If AE is 921, then EC is equivalent to that. First, you subtract 9 from 921, then divide by nineteen to get your answer: x = 48.
Answer to the question
Answer:
x = 48.
Step-by-step explanation:
AE and EC are equivalent. Subtract 9 from 921, and divide by 19 to get the value of x, which is 48.
Phil's average is 0.250. This is about 5/6 as much as Joe's average. What is Joe's average? (Write answer is decimal form - do not round).
Let Joes average = x
Phil’s average is 0.250 and is 5/6X ( 5/6 of Joe’s)
5/6x = 0.250
Solve for x by dividing both sides by 5/6. When dividing by a fraction, flip the fraction over and multiply;
X = 0.250 x 6/5 = (0.250 x 6)/5 = 1.5/5 = 0.30
Joes average is 0.3

Soda is sold in aluminum cans that measure 7 inches in height and 2.8 inches in diameter. How many cubic inches of soda are contained in a full can?
9514 1404 393
Answer:
43.1 in³
Step-by-step explanation:
The volume can be computed using the formula ...
V = (π/4)d²h . . . . where d is the diameter and h is the height
For your dimensions, the volume is ...
V = (π/4)(2.8 in)²(7 in) ≈ 43.103 in³
A full can contains a volume of about 43.1 cubic inches.
What's the inverse of ƒ(x) = 3x3 – 4?
Answer:
Step-by-step explanation:
y = 3x³ -4
the inverse is found by changing x with y and y with x than solve for y
x = 3y³ -4
x+4 = 3y³-4+4; add 4 to both sides
x+4 = 3y³
(x+4)/3 =y³ ;divide both sides by 3
∛((x+4)/3) = y ;cube root both sides
the inverse function of f(x) =3x³-4 is
[tex]f(x)^{-1} =\sqrt[3]{\frac{x+4}{3} }[/tex]
3. Antoinette is building a rectangular pen with 78 feet of fencing. If the length of the pen is 5
feet longer than its width, what are the dimensions of the pen?
Width
Length
NUMBER 3
Answer:
length = 22
Width = 17
Step-by-step explanation:
78 = 2(w+5) + 2(w)
78 = 2w + 10 + 2w
78 = 4w + 10
68 = 4w
w = 17
l = 17 + 5 = 22
which integer is 3 less then -7
Answer:
-10
Step-by-step explanation:
you did not have to come on here for this annswer could have subtracted -7-3=-10
Answer:
Step-by-step explanation:
Any question that has less in it, is a question that you should pay attention to.
-7 -3 = - 10
You have to think of this the way you would money. Which would you rather owe - 7 dollars or - 10 dollars. Surely you would say that - 7 is better than - 10.
So - 10 looks like it is three less than - 7
It works if the money thing makes sense to you.
If that doesn't work then think of a number line. As you keep on going left, the number looks like it is getting bigger, but is it. Again - 10 is smaller than - 7.
If you are talking about plus numbers then 3 less then 7 is not 10. It is 4.

[tex] \large{ \boxed{ \tt{OUR \: ANSWER : \underline{ \$ \: 583.3125}}}}[/tex]
Well , You can solve this question using two ways. I'm gonna use the both ways to make you clear and the one which you can easily understand , pick up that way and start solving another question as similar as this one.
[tex] \large{ \tt{❃ \: FIRST \: METHOD }} : [/tex]
This method is related to the unitary method. Let's start :
We're provided - Amount Kelly earns per hour for gardening = $ 12.75 and we're asked to find out the amount she earn if she worked 45.75 hours this month.We know , Kelly probably earns more money if she worked 45.75 hours comparison to if she worked 1 hour. So You just multiply 45.75 & 12.75 , you would get $ 583.3125 and that's your final answer.[tex] \large{ \tt{❃ \: SECOND \: METHOD}} : [/tex]
This method is related to the proportion. If you haven't learned about it yet , use the above way to solve the similar type of questions. Let's start :
Let Kelly earns X dollars if she worked 45.75 hours this month. [ Now , See the attached picture ] Here , we can see the time is increased which implies that money will surely be increased. Such type of proportion is called direct proportion.Here , the ratio of time ( in hours ) = 1 : 45.75 and the ratio of amount ( in dollars ) = 12.75 : x . Now , Set up an equation and solve for x :[tex] \large{ \tt{ ❁ \: \frac{1}{45.75} = \frac{12.75}{x}}} [/tex]
[tex] \large{ \tt{↦ \: 1 \times x = 45.75 \times 12.75}}[/tex]
[tex] \large{ \tt{↦x = \$ \: 583.3125}}[/tex]
Hence , She earned $ 583.3125 .▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁
Write a function to describe the following scenario.
A taxi driver charges a $5 flat fee to
enter the car and $0.50 per mile.
What is the total cost of a taxi ride?
y = [?]x + [?]
Answer:
y = $0.50x + $5. $7 if you went 4 miles
Step-by-step explanation:
$0.50 will be the coefficient for the variable x since the amount changes based on how many miles you ride. $5 will be the amount you are charged just for getting into the taxi and doesn't change depending on how many miles you go.
[tex]y=0.50x+5[/tex]
I used x = 4 for the number of miles travelled.
[tex]y=0.50(4)+5[/tex]
[tex]y=2+5[/tex]
[tex]y=[/tex] $7 total cost
1.26×10⁹ as a Ordinary Number
Answer:
1,260,000,000
Can someone help me?
Answer:
1. True, because when performing the calculations in both sides of the equation, we find that the left value is indeed the same as the right value
4-3+5 = 1+5 = 6
-6+8+4 = 2+4 = 6
6=6, so the sentence is correct
2+5 = 19-12 => 7=7, true
5-4-3-2-1 = 30-34-1 => -5=-5, true
2(x+5)-4x = 3(x-2)-5x+16
=> 2x+10-4x = 3x-6-5x+16
=> -2x+10 = -2x+10, true
Step-by-step explanation:
the other two sentences lead to false
4/5 + 1/5 = 2 - 1 - 1, => 5/5 = 1 = 0, false
2(x+8) = 2x-8, => 2x+16 = 2x-8 => 16=-8, false

For the two triangles:
1/2(6x5)=15 (for 1 triangle, notice there are 2 so -> 30)
For the 2 rectangles:

: (570)=2 م Let m 1 = (342) and m .16 = m1= =OFE هم (
Answer:
x = 6
m<1 = 20°
m<CFE = 140°
Step-by-step explanation:
m<1 = (3x + 2)°
m<2 = (5x - 10)°
✔️Given that FB bisects AFC, therefore,
m<1 = m<2
Substitute
3x + 2 = 5x - 10
Collect like terms and solve for x
3x - 5x = -2 - 10
-2x = -12
-2x/-2 = -12/-2
x = 6
✔️m<1 = 3x + 2
Plug in the value of x
m<1 = 3(6) + 2
m<1 = 18 + 2
m<1 = 20°
✔️m<CFE = 180° - m<AFC (angles on a straight line)
m<CFE = 180° - (m<1 + m<2)
m<CFE = 180° - (20 + 20)
m<CFE = 180° - 40°
m<CFE = 140°

Hello! answer: 17
Step-by-step explanation:
15 × 15 = 225
8 × 8 = 64
225 + 64 = 289
√289 = 17 17 × 17 = 289 Therefore the answer is 17 hope that helps!
Answer:
17
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]8^{2} + 15^{2} = c^{2}[/tex]
289 = [tex]c^{2}[/tex]
square root both sides
