Answer:
Rajesh applied the wrong formula
Step-by-step explanation:
The problem is on mensuration of flat shapes, circles.Rajesh applied the wrong formula for the calculation of the area of a circle
he used [tex]area= \pi d[/tex]
Rajesh is expected to solve for the area of a circle using the right formula, which is
[tex]area= \frac{ \pi d^{2}}{4} \\or\\area= \pi r^{2}[/tex]
substituting our data we have
[tex]area= 3.142*10^{2} \\area= 3.142*100\\area= 314.2[/tex]

Standard form of the equation that goes through (1, 2) with a slope of 7, please!
Answer:
7x - y = 5
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in point- slope form and rearrange into standard form.
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 7 and (a, b) = (1, 2)
y - 2 = 7(x - 1) ← in point- slope form
y - 2 = 7x - 7 ( subtract y from both sides )
- 2 = 7x - y - 7 ( add 7 to both sides )
5 = 7x - y , that is
7x - y = 5 ← in standard form
The value of y varies inversely as the cube of x and y=1 when x=6. Find the value of y when x =2.
Answer:
y=27 when x=2
Step-by-step explanation:
y varies inversely as the cube of x
y=k(1/X^3)
y=1 when x=6
y=k(1/X^3)
1=k(1/6^3)
1=k(1/216)
k=1÷1/216
K=1×216/1
k=216
find y when x=2
y=k(1/X^3)
y=216(1/2^3)
y=216(1/8)
y=216/8
y=27

How would you explain function notation to a friend?
Many students seem puzzled by function notation well after it has been introduced, and ask “why can’t we just write
y = 3x instead of
f(x) = 3x ?”. To motivate the use of function notation and improve understanding, I advocate using multi-variable functions instead of single-variable functions in introducing this notation. My introduction usually proceeds something like this:

sarra binged watched 12 of the 15 episodes of " the dudes i dont dig"; what percent of the shows has she watched?
Answer:
Sarra watched 80% of the show.
Step-by-step explanation:
12÷15×100
Answer:
80%
Step-by-step explanation:
You have to take the total number of TV show episodes and divide it by the amount the person watched, in this case 15/12. Next, you have to multiply the answer you get by 100, in this case 0.8*100, this leads you to move the decimal point two places to the right giving you 80%.

How can you determine the distance between the corners without measuring it?
Answer:
The distance formula
Step-by-step explanation:
This was kind of vague, but I'll try my best.
You can use the distance formula! It is basically the pythagorean theorem.
Here's the steps,
1. draw a right triangle from the corners. If you have graph paper, this should be relatively easy.
2. locate the hypotenuse, that is the distance.
3. next use the pythagorean theorem/ distance formula (same thing)
4. Except, instead of a and b and c, replace them with
(Change in x)²+(change in y)²= distance²
Now plug in the values
Now you're done!
Aziz and Tuan collected 3600 bottles for recycling last year.
Aziz collected 5 times as many bottles as Tuan.
How many bottles did Tuan collect?
please write out the equation with the answer in this format.
x÷x=x
Answer:
Hai
6x=3600
x=600
so tuan collected 600 bottles.
aziz collected 3000 bottles.
5x(aziz)+x(tuan)=3600
good luck (:
Answer:
x = 3600 ÷ 6600 bottlesStep-by-step explanation:
Let x represent the number of bottles Tuan collected. Then 5x is the number Aziz collected. Their total is ...
x +5x = 3600
6x = 3600 . . . . . . collect terms
x = 3600 ÷ 6
x = 600
Tuan collected 600 bottles.

Dr. Khan is combining a 20% acetic acid solution with a 60% acetic acid solution. She wants to obtain 10 liters of a 40% acetic acid solution, how many liters of the 20% acetic acid solution does Dr. Khan need to create the 40% acetic acid solution?
Answer:
Dr Khan will add 5 liters of 20% acetic acid solution.
Step-by-step explanation:
Dr Khan is combining two solutions of acetic acid with the given concentrations of 20% and 60% respectively.
Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters
Volume of 60% solution used will be = (10 - a) liters
Now the equation will be,
Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%
[tex]a\times \frac{20}{100}+(10-a)\times \frac{60}{100}=10\times \frac{40}{100}[/tex]
20a + 60(10 - a) = 400
20a + 600 - 60a = 400
600 - 40a = 400
40a = 600 - 400
a = [tex]\frac{200}{40}[/tex]
a = 5 liters
Therefore, Dr Khan will add 5 liters of acetic acid to get 40% acetic acid solution.
Solution:
Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters
Volume of 60% solution used will be = (10 - a) liters
Equation will be,
Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%
a*20/100+(10-a)*60/100=10*40/100
20a + 60(10 - a) = 400
20a + 600 - 60a = 400
600 - 40a = 400
40a = 600 - 400
a=200/40
a = 5 liters
Thus, Dr Khan need to create 5 liters of acetic acid to get 40% acetic acid solution.

A store is having a sale on chocolate chips and walnuts. For 3 pounds of chocolate chips and 5 pounds of walnuts, the total cost is $16. For 6 pounds of
chocolate chips and 2 pounds of walnuts, the total cost is $22. Find the cost for each pound of chocolate chips and each pound of walnuts.
Cost for each pound of chocolate chips: $
Cost for each pound of walnuts: $
Answer:
Step-by-step explanation:
3c + 5w = 16
6c + 2w = 22
-6c - 10w = -32
6c + 2w = 22
-8w = -10
w = 10/8 = 5/4 = $1.25 per lb
3c + 5(1.25) = 16
3c + 6.25 = 16
3c = 9.75
c = $3.25 per lb
