Step-by-step explanation:
First of all, let us lay down the clues;
●There is a 20% discount on the mobile set.
●The price after the discount is Rs 13 920
●We need to find the original price.ie.(100% stands for original price)
Now let's start;As there is a 20% Discount on the m.Set, we need to find the exact percentage decrease.
So,
100%-20%= 80%
Now let's do Direct Proportion,
80%= Rs 13 920
1%= 13 920/80
100%= 13 920/80*100=Rs 17 400
Your FINAL ANSWER;RS 17 400
Find the value of n that makes the equation true.
n+5=n+7
Answer:
No solution
Step-by-step explanation:
Answer:
There's not a value of n so that n + 5 = n + 7
Step-by-step explanation:
if n + 5 = n + 7, then:
subtract 5 from each side of the equation:
n = n + 2 which does not have a solution for n
A cylinder has a radius of 2x + 3 and height of 3x + 2. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula V= πr^2h for the volume of a cylinder.
Answer:
[tex]v = \pi {r}^{2} h \\ v = \pi {(2x + 3)}^{2} (3x + 2) \\ v = \pi(4 {x}^{2} + 12x + 9)(3x + 2) \\ v =( 12 {x}^{3} + 36 {x}^{2} + 27x + 8 {x}^{2} + 24x + 18)\pi \\ v =( 12 {x}^{3} + 44 {x}^{2} + 51x + 18)\pi[/tex]

Write the number 0.00004 in scientific notation.
Answer:
4.0 x 10^-5
Step-by-step explanation:
Answer:
4*10^-5
Step-by-step explanation:
Start by counting the zeros to the right of the decimal if 0<x<1. Stop when you hit a digit between 1 and 9Add 1 to the number of zerosThis is the powerExpress the number as one between 1 and 9 The power is changed to a negative, if 0<x<10.00004 has 4 zeros. Add 1 = 5
The power on 10 becomes negative (-5)
4 is a number between 1 and 9 inclusive.
4 * 10^-5
Simplify the expression. Write your answer as a power.
(-4).(-4)
The simplified expression is
Answer:
(-4).(-4) = 4^2
Step-by-step explanation:
First, some rules that we need to remember:
if A is a positive number, then:
-A = (-1)*A
Also:
A*A = A^2
We also should remember that we can multiplicate in any order we want, this is:
A*B*C = (A*B)*C = A*(B*C)
And we also can change the order of the numbers:
A*B = B*A
And finally, we need to remember the sign rules for multiplication.
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Ok, now let's look at our expression.
(-4)*(-4)
First, we can rewrite this as:
( (-1)*4)*((-1)*4)
And we can rearrange the numbers to:
(-1)*(-1)*4*4
Now let's multiplicate the first two ones, because of the sign rule, we know that the outcome will be positive, and 1 times 1 is equal to 1,
(-1)*(-1) = 1
Then:
(-1)*(-1)*4*4 = 1*4*4 = 4*4
And we know that when a number is multiplied by itself we can rewrite it as:
4*4 = 4^2
Then:
(-4).(-4) = 4^2
The simplified expression is 4^2
Lin opened a lemonade stand during the summer. She
noticed that she sold more lemonade on warmer days.
For each day she sold lemonade, she plotted the point
(t,c), where t represents high temperature and c
represents cups of lemonade sold.
b. A computer program found that the line c= 2t - 89
is a good fit for the data. Use this equation to predict
how many cups of lemonade Lin might sell on a day
when the high temperature is 74 degrees.
c. the high temp this Sunday is expected to be 5 degrees warmer that the high temp this Saturday. using the line c = 2t - 89 how many more cups of lemonade should lin expect to sell on Sunday than Saturday? explain or show your reasoning
Answer:
59 cups ;
10 cups
Step-by-step explanation:
Given that he fitted model :
c = 2t - 89
Where, c = cups of lemonade sold ; t = high temperature
On a day when high temperature is 74 degrees ; cups of lemonade sold
Hence,
c = 2t - 89
c = 2(74) - 89
c = 148 - 89
c = 59 cups
Sunday is expected to be 5 degree warmer than on Saturday :
The number of cups sold on Sunday using the fitted model should be :
Difference in temperature between Saturday and Sunday multiplied by the slope value
Slope value from the model = 2
Temperature difference = 5
Difference in Number of cups :
2 * 5 = 10 cups
Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
Answer: 59 cups

measure of angle A: 28 degrees
BC ≈ 13.3
BA = 28.3
hope this helps
Step-by-step explanation:
angle A
90- 62 = 28
angle A = 28
BC
tan (A) = BC / 25
(25) tan 28 = BC / 25 (25) multiply 25 on both sides to cancel it out from BC
13.292735 = BC
BC ≈ 13.3
BA
BA^2 = 13.3^2 + 25^2 Pythagorean theorem
BA ≈ 28.3

Answer:
the mealworm would've crawled 0.35 meters in one minute
Step-by-step explanation:
Ok, 2.1 meters in 6 minutes, how long did it travel in 1 minute?
to get 6 minutes to 1 minute, we need to divide 6 by 6 to get to 1.
we need to divide 2.1 by 6
2.1 / 6 = 0.35

In order for you to carry a bag on the plane, it must t inside the Carry-on Baggage Check Box.
The Carry-on Baggage Check Box has dimensions of approximately 22" x 14" x 9". Your leather bag has a
height of 18 inches, a depth of 12 inches, and a width of 8 inches. Your canvas bag has a height of
18 inches, a depth of 15 inches, and a width of 10 inches.
1. What is the volume of the Carry-On Baggage Check Box?
2. What is the volume of the leather bag?
3. What is the volume of the canvas bag?
4. Which bag will denitely t into the Check Box? Explain.
Step-by-step explanation:
guessing
volume is always unit cubed
so in this case inches cubed or in^3
so multiply all 3 numbers
carry on is 22×14x9= 2772 in^3
leather is 18×12×8 = 1728 in^3
canvas is 18×15×10 = 2700 in^3 but the depth in ge's canvas 15" in larger than the carry on checklist
so
the leather will definitely fit
Please help with this word problem!
Answer:
a)
x = (158-112) / 1x
or 158-112 / x
b) 112+ 23 /158-23 = x
or if you want x to be the same value as the first part then you could write
112+x / 158-x = 135/135
or revise as an equality
23 ≤ 112 < 158
112 + 23 = 158
112 + x = 158
Step-by-step explanation:
Tailwind speed
x = 158-112 / 2
x = 46/2
x = 23 knots
Speed
x = 112 + 23 / 158-23
x = 135 / 135 m/h = same speed as stated in question.
