Help immediately!!!!! What is the average rate
Answer:
the average rate of change is 4
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
1. Information
Another word for the average rate of change is the slope. The question is essentially asking, what the slope is over the interval of [3, 4]. Hence, one will use the following points, that are on this given function;
(3, -5), (4, -1)
One must also know that the formula for slope is;
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
2. Solving
Input the given points into the formula and solve.
[tex]\frac{(-1)-(-5)}{(4)-(3)}[/tex]
[tex]\frac{-1+5}{1}[/tex]
[tex]\frac{4}{1}[/tex]

Mohammad divide Rs 82000 into two parts such that the amounts at 5% per annum compound interest in 2 years and 3 years are equal respectively.How much amount does he divide?
Answer:
Rs 42000 and Rs 40000
Step-by-step explanation:
Given that Rs 82000 is divided into two parts.
Let the first part be Rs x which is compounded annually at the interest of 5% per annum for 2 years.
The rate of interest = 5%=0.05
The total amount after 2 years [tex]= x(1+0.05)^{2}\cdots(i)[/tex]
The other part is Rs 82000-x which is compounded annually at the interest of 5% per annum for 3 years.
The total amount after 3 years [tex]= (82000-x)(1+0.05)^{3}\cdots(ii)[/tex]
As both the amounts are equal, so from equation (i) and (ii)
[tex]x(1+0.05)^{2}=(82000-x)(1+0.05)^{3} \\\\x(1.05)^{2}=82000(1.05)^{3} -x(1.05)^{3} \\\\x(1.05^2+1.05^3)=82000\times 1.05^3 \\\\x(2.260125)=94925.25 \\\\x=94925.25/2.260125 \\\\[/tex]
x= 42000
And the other part = 82000-42000 = Rs 40000
Hence, he divides the money as
Rs 42000 at 5% per annum compound interest in 2 years and
Rs 40000 at 5% per annum compound interest in 3 years.
a weights m kg,b weight is 20 kg less than three times that of a. If their total weight is 100 kg. Find the weight of a
Answer:
30kg
Step-by-step explanation:
what we know is that 3a - 20kg is b. and if a + 3a -20kg = 100kg, it becomes algebra .
So, we move it over to the sides:
4a = 120kg
(here i moved -20kg to the 100kg and did the reverse. I also added the a's)
which means a = 120kg divided by 4
a = 30kg
If AABC = ADEC,

В B.
x = [?]
Answer:
x = 30
Step-by-step explanation:
65 + 55 = 120
angle B must equal 60
angle B is labeled as 2x
set up equation to solve for 'x': 2x = 60
x = 30
add up all angles to make sure you get 180 degrees
It is worked out that if 4 ladles full of soup are given to each person,
160 people can be fed.
The customers have complained in the past that the portions are too small.
The cook decides to give 5 ladles full of soup to each person.
How many people can now be fed soup
Answer:
128 people
Step-by-step explanation:
160 people multiplied by 4 ladles per person equal 640 ladles in total
640 ladles divided by 5 ladles each equals 128 people

The sales tax in your city is
4.4% and an item costs
$3 before tax.
How much tax would you pay on that item?
Round to the nearest hundredth or cent.
Answer:
$0.13
Step-by-step explanation:
To find how much tax you would pay, find 4.4% of 3:
3(0.044)
= 0.132
Round to the nearest hundredth:
0.132
= 0.13
So, you would pay $0.13 in tax

I need help in this, please
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to get the following;
1. Initial deposit
The initial deposit is the value of y when x = 0
We can see this at x = 1000
2. slope and y-intercept
The y-intercept is the y-value of the graph when x = 0
It is the point at which the graph crosses the y-axis
From the plot, we can see that the y-intercept is 1000
To get the slope, we select and two points on the graph and apply the slope formula
The points selected are;
(2,2000) and (4,3000)
The formula for the slope is;
y = (y2-y1)/(x2-x1)
y = (3000-2000)/(4-2) = 1000/2 = $500 per month
3. Generally the equation of a line is;
y = mx + b
where m is slope and b is the intercept
So the equation will be;
y = 500x + 1000
4. The meaning of slope in the graph represents the unit of amount saved per month in the plan. It is just giving us a breakdown of what’s saved by each month on the plan

A store is having a sale where everything is discounted 30%. Find the discount and the sales price if a customer buys an item that normally sells for $365.
Answer:
The discount is $109.50 and the sales price is $155.50
Step-by-step explanation:
30% of 365 is 109.5
356-109.5=155.5
Solve each of the following equations
Answer:
a. x = 10
b. x = 3/5
c. x = 16
d. x = 21/32
Step-by-step explanation:
For all of these problems, it would be simpler to get rid of the fractions entirely and to do that you need to multiply each part of the equation by the least common denominator (LCD; the first a number or variable that both of the denominators can be divided evenly by((you get it by multiplying the denominators by that number/variable (8*1, 8*2,8*3, etc.) and stop until both denominators are the same)) of what you're adding in this case.Note that if the denominators that you're adding are the same then you just multiply everything by that.Also note that the LCD's do not replace the denominators pf the original equation! Simply multiply the numerators by the LCD and then solve the problem accordingly!a - 2x/3 + (x+3)/3 = 11
For this case, the least common denomimator is 3. Multiply everything by 3. This leaves 2x + x+3 = 33. Combine like terms. 3x+3 =33 Subtract 3 from 33, leaving 30 and finally divide 30 by 3x to get 10, your answer.b - 3/x + 6/x = 15
Multiply everything by x. This leaves 3 + 6 = 15x. Combine Like Terms so 9 = 15x. Divide 9 by 15, leaving x to be 9/15, or 3/5 when simplified (both 9 and 15 can be divided by 3).c - x/2 + x/8 = 10
In this case, the LCD is 16. So multiply everything by 16, leaving 16x/2 + 16x/8 = 160. Simplify, leaving 8x + 2x = 160. Combine like terms, so 10x = 160. Divide 160 by 10, leaving you with 16.d - 4/x + 5/4x = 8
The LCD isn't always going to be a number as seen here and in b, but they were the same as if it were a number. Here the LCD is 4x so multiply everything by 4x. This leaves you with 16x/x +20x/4x = 32x. Simplify accordingly, leaving you with 16 (x variables cancel) + 5 =32x. Simplify yet again, leaving 21 = 32x. Divide 21 by 32, leaving you with 21/32 as your answer (the answer can't be simplified further).Apologies for the long explanations--it's not something I do very well.
Find each missing angle measure
3=
4=
Answer:
<4 = 88
<3 = 92
Step-by-step explanation:
The sum of the angles of a triangle is 180
<4 + 45+ 47 = 180
<4 + 92 = 180
< 4 = 180-92
<4 = 88
We know the <3 and <4 form a line
<3 + <4 = 180
<3 + 88 = 180
< 3 = 180-88
<3 = 92

y2 = 2
y1 = 0
x2 = 0
x1 = - 4
Equation
m = (y2 - y1)/(x2 - x1)
Solution
m = (2 - 0)/(0 - - 4)
m = 2/4 = 1/2
Find b
y = mx + b
y = 2
x = 0
2 = 1/2x + b
2 = 1/2*0 + b
b = 2

Step-by-step explanation:
Answer:
x = −8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(x + x) + (75 +53 + 68) = 180 (Combine Like Terms)
2x + 196 =180
Step 2: Subtract 196 from both sides.
2x + 196 − 196 = 180 −196
2x = −16
Step 3: Divide both sides by 2
x = -8

x ÷ 7 + 1 = 5 find the value of x
Answer:
28
Step-by-step explanation:
x/7+1=5
-1 -1
x/7=4
x/7*7=4*7 ( do the inverse operation to get rid of 7, which is multiplication)
x=28
Answer:
x=28
Step-by-step explanation:
x÷7+1=5
Firstly,
Group like terms
x÷7=5-1
x÷7=4
Secondly,
So now 7 will cross the equal sign
x=4×7
We have ×7 because when a number number with a division sign crosses an equal sign it becomes multiplication.
x=28

Karen will divide her garden into equal parts. She will plant corn in 12 20 of the garden. What is the fewest number of parts she can divide her garden into?
Given that,
Karen will divide her garden into equal parts. She will plant corn in 12/20 of the garden.
To find,
The fewest number of parts she can divide her garden into.
Solution,
It is mentioned that she will plant corn in 12/20 of the garden.
If we divide both numerator and denominator by 4, it will become:
[tex]\dfrac{12/4}{20/4}=\dfrac{3}{5}[/tex]
It means the fewest number she can divide her garden into is 4. 3/5 part is planted with corn and rest 2/5 is not planted with corn plant.
