x=14
GH= 14+10 =24
GJ = GH +HJ = 24+ 8=32
Which of the following are not a perfect cube ? 6859 , 10648 , 1728
Answer:
6859 is not perfect cube.
Step-by-step explanation:
First we will find all factors under the cube root: 6859 has the cube factor of 361. Let's check this width ∛361*1=∛6859. As you can see the radicals are not in their simplest form. Now extract and take out the cube root ∛361 * ∛1. Cube of ∛361=19 which results into 19∛1 All radicals are now simplified.

(a) The marked price of a radio is Rs. 6,000. After giving a certain percent of dis-
count and leaving 10% VAT, its price becomes Rs. 5,610. What is the discount
percent ?
Answer:
6.5%
Step-by-step explanation:
M.P= ₹6,000
Amount excluding VAT= 5,610
discount= x/100
discount= 6000*x/100=60x
equating
6000-60x= 5610
6000-5610=60x
390=60x
390/60=x
6.5=x
therefore, there is a discount of 6.5%

The present age of Joyal’s mother is three times the present age of joyal. After 5 years their ages will add up to 66. Find their present age
｡☆✼★ ━━━━━━━━━━━━━━ ☾
Let's form some equations:
I'll refer to Joyal's age as 'x'
Therefore, his mother's age is '3x'
Here is the equation we create:
x + 5 + 3x + 5 = 66
Simplify this:
4x + 10 = 66
- 10 from both sides:
4x = 56
/4 on both sides
x = 14
3(14) = 42
So, currently Joyal is 14 and his mother is 42

Which values of a and b make the equation true? (2xy)^4/4xy=4x^ay^b
Answer: a=3, b=3
Step-by-step explanation:
Let's rewrite this expression on the left side so that it matched the form on the right side.
[tex]\frac{(2xy)^4}{4xy}=\frac{16x^4y^4}{4xy}=4x^3y^3[/tex]
Now, you can see the left side matches the same form as the right side.
4x³y³=4xᵃyᵇ
Since they're the same equation, a=3 and b=3.

The cost per month is a good way to compare different modes of transportation. True False Please help and fast. I am in need of desperate help!!!!
Answer:
False
Step-by-step explanation:
Cost is not a complete ways to compare different modes. We also need to look at the time of each mode of transportation. Walking is very cheap (the cost of shoes and water) but would take a very long time. We would also have to look at the convenience factor. The bus may be cheap but it may not run when and where you need it.
It is, that would be true
A flock of birds was flying around a tree. When they landed, three birds to a branch, no branches were left and one bird had to keep flying around the tree. Then, all the birds took off, flew around the tree again and landed to sit, four to a branch. Now, no birds were left flying but one branch had no birds sitting on it. How many branches were on the tree and how many birds were in the flock?
Answer: 5 branches and 16 birds.
Step-by-step explanation:
If the number of birds is B, and the number of branches is N.
First we have the equation:
B = 3*N + 1
(3 birds per branch + 1 that was flying around)
for the second equation we have:
B = 4*(N - 1)
(4 birds per branch, but one branch had no birds on it, so there are N -1 branches used)
now we can write:
3*N + 1 = 4*(N - 1)
3*N + 1 = 4*N - 4
4 + 1 = 4*N - 3*N
5 = N
So we had 5 branches, now we can replace it in one of the equations and find the number of birds.
B = 3*N + 1 = 3*5 + 1 = 16

A quadratic relation in the form y = ax² + bx + c and has a y-intercept of (0, 1). The parabola also goes through the points (2, 9) and (-5, 16). Determine the parameters of this quadratic relation (the values of a, b, and c).
Answer:
value of
a = 1
b = 2
c =1
and equation is
y = x² + 2x + 1
Step-by-step explanation:
Given quadratic equation y = ax² + bx + c
It has y-intercept of (0, 1)
thus, point (0,1) will satisfy equation y = ax² + bx + c.
putting 1 in place of y and 0 in place of x in equation y = ax² + bx + c we have
1 = a*0² + b*0 + c
c = 1
Thus, equation until now is y = ax² + bx + 1
____________________________________________________
The parabola also goes through the points (2, 9) and (-5, 16)
point (2, 9) will satisfy equation y = ax² + bx + 1.
putting 9 in place of y and 0 in place of 2 in equation y = ax² + bx + 1 we have
9 = a*2² + b*2 + 1
9 = 4a+2b+1
=>4a+2b = 9-1 = 8
dividing both side by 2 we have
4a/2+2b/2 = 8/2
=> 2a + b = 4
b = 4-2a
____________________________________________________
The parabola also goes through the points (2, 9) and (-5, 16)
point (-5, 16) will satisfy equation y = ax² + bx + 1.
putting 9 in place of y and 0 in place of 2 in equation y = ax² + bx + 1 we have
16 = a*(-5)² + b*(-5) + 1
16 = 25a-5b+1
=>25a-5b = 16-1 = 15
dividing both side by 5 we have
25a/5-5b/5 = 15/5
=> 5a - b = 3
second equation is 5a - b = 3
substituting value of b as 4-2a from first equation we have
5a - (4-2a) = 3
=> 5a - 4+2a = 3
=> 7a = 3+4 = 7
=> a = 7/7 = 1
value of b is 4-2a
substituting value of a as 1 in 4 - 2a we have
b = 4 - 2*1 = 4-2 = 2
Thus,
value of
a = 1
b = 2
c =1
and equation is
y = x² + 2x + 1

What are the two solutions of 2x^2 = -X^2 - 5x - 1?
A. the y-coordinates of the intersection points of the graphs of y = 2x^2 and y = x^2 – 5x - 1
B. the x-coordinates of the x-intercepts of the graphs of y = 2x^2 and y = -x^2 – 5x - 1
C. the x-coordinates of the intersection points of the graphs of y = 2x^2 and y = -x^2 – 5x - 1
D. the y-coordinates of the y-intercepts of the graphs of y = 2x^2 and y = -x^2–5x - 1
Answer:
Step-by-step explanation:
Let's solve 2x^2 = -X^2 - 5x - 1. Consolidate all terms on the left side and write 0 on the right side:
3x^2 + 5x + 1 = 0. This is a quadratic equation. Let's solve it for x using the quadratic formula:
a = 3, b = 5, c = 1, and so the discriminant is b^2 - 4ac = 5^2 - 4(3)(1) = 13. Because the discriminant is positive, we know that there are two distinct, real roots; the graphs of y = 2x^2 and y = x^2 - 5x - 1 intersect in two places whose x-coordinates are the real roots mentioned above.
Answer A is not correct as stated, but would be correct if we were to replace "the y-coordinates" with "the x-coordinates."
Answer C would be correct if and only if we write y = x^2 - 5x - 1.
Answer:
C: the x-coordinates of the intersection points of the graphs of y = 2x2 and y = –x2 – 5x – 1

Two drivers moving in opposite directions on an 18-mile circular racetrack cross each other at a certain point. If one of them has an average speed of 1.2 miles per minute and the other has an average speed of 1.8 miles per minute, how many minutes will it take for them to cross each other again?
Answer:
They both would cross each other again in the next 5 minutes
Step-by-step explanation:
The first thing to do here is to calculate the lowest common multiple of the average speed of both drivers.
That would be the lowest common multiple of 1.2 miles per minute and 1.8 miles per minute.
That would be 3.6 miles per minute.
Now to get the time at which they would cross each other again, we simply divide the total distance around the circular track by the lowest common multiple of their average speed.
That would be 18/3.6 = 5
This means they would cross each other again in the next 5 minutes

Answer:
The series converges to -1.5.
Step-by-step explanation:
This is a geometric series, so it converges if the number in parenthesis is between -1 and 1.
-1 < -3/5 < 1, so the series converges by the geometric series test.
Now we can plug this into the calculator (on TI-84, it's Math->0 summation) to find that the sum is -1.5. You can use 100 or another big number as a placeholder for infinity.
