Answer:
1 and 11/15.
Step-by-step explanation:
To solve, we can separate the integers from the fractions.
(6 - 4) + (2/5 - 2/3)
= 2 + (6/15 - 10/15)
= 2 + (-4/15)
= 1 + 15/15 - 4/15

Nandini makes 'halwa' one evening and divides it into four equal portions for her family of four. However, just as they are about to eat it, an unexpected guest arrives and Nandini has to now re-divide the halwa into five equal portions. By what percentage has each family member's share reduced due to this? A. 5% B. 10% C. 20% D. 25%
Answer:
5%
Step-by-step explanation:
Total 'halwa' made = 1
Divided into four equal portion = 1/4
Arrival of an unexpected guest = 1/5
By what percentage has each family member's share been reduced:
Change in the sharing proportion:
Previous share ratio - new sharing ratio
(1/4 - 1/5) = (5 - 4) / 20 = 1/20
That means total reduction in the sharing = 1/ 20
Since each member comes contributed equally:
Reduction in each family member's share ;
(1 / 20) ÷ 4
(1 / 20) * 1/4 = 1/ 80
Percentage reduction:
(Reduction / original share) * 100%
[(1/80) ÷ (1/4)] * 100
(1/80 * 4/1) * 100%
(1/20) * 100%
= 5%
Reduction in each family members share = 5%
What is the volume of the cone shown below?
Answer:
C. 96 pi
Step-by-step explanation:
Formula for volume of cone = 1/3 * h * pi * r^2
1. 1/3 * 18 * 4^2 * pi
2. 96 pi
I hope this helps
Answer:
C. 96π cubic units
Step-by-step explanation:
The volume of a cone can be found using the following formula.
[tex]V=\frac{1}{3} \pi r^2h[/tex]
The radius of the cone is 4 units and the height is 18 units.
r= 4 units
h=18 units
Substitute the values into the formula.
[tex]V=\frac{1}{3} \pi (4units)^2(18 units)[/tex]
First, evaluate the exponent, 4 units^2.
4 units^2= 4 units * 4 units= 16 units^2
[tex]V=\frac{1}{3}\pi(16 units^2)(18 units)[/tex]
Next, multiply 16 units^2 and 18 units
16 units^2*18 units= 288 units^3
[tex]V=\frac{1}{3}\pi(288 units^3)[/tex]
Next, multiply 1/3 and 288 units^3, or divide 288 units^3 by 3.
1/3 * 288 units^3 =96 units^2
288 units^3/3=96 units^3
[tex]V=\pi*96units^3[/tex]
This can be rewritten as:
[tex]V= 96\pi units^3[/tex]
The volume of the cone is 96π cubic units. Therefore, C is the correct answer choice.
if y is directly proportional to x and y=5 when x=2, find the value of y when x =7
Answer:
y = 17.5
Step-by-step explanation:
y = kx
→ Substitute in the values
5 = 2k
→ Divide both sides by 2 to isolate k
k = 2.5
⇒ y = 2.5x
→ Substitute in x = 7
y = 2.5x ⇔ y = 2.5 × 7 ⇔ y = 17.5

The area of a square field is 60025 square metre. Find the perimeter of the field. With explanation .
Answer: P≈2.4×10 power5
Step-by-step Explanation: P=4a=4·60025=2.401×10 power5
Answer:
[tex]\huge \boxed{\mathrm{980 \ m}}[/tex]
Step-by-step explanation:
The formula for the area of a square is:
[tex]A=s^2[/tex]
The area is given as 60025 m².
We need to find the length of each side.
[tex]60025=s^2[/tex]
Take the square root of both sides.
[tex]s=245[/tex]
The side length is 245 m.
The formula for the perimeter of a square is:
[tex]P=4s[/tex]
Plug in the value for the side length.
[tex]P=4(245)[/tex]
[tex]P=980[/tex]
The perimeter of the field is 980 m.
find the interest rate r when p = 800, a = 2700, and t = 3.
Answer:
r = 0.5 or 1/2
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)^t
Simply plug in our known variables:
2700 = 800(1 + r)³
Now we solve for r:
Divide both sides by 800
27/8 = (1 + r)³
Take the cube root on both sides
∛27/8 = ∛(1 + r)³
Simplify
3/2 = 1 + r
Subtract 1 on both sides
r = 1/2
r = 0.5
Answer:
For compound interest, 50%.
Step-by-step explanation:
(I'm assuming this question is asking for the compound interest):
The formula for compound interest is given by:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Plug in the values we know. We can use 1 for n:
[tex]2700=800(1+r)^3\\27/8=(1+r)^3\\1+r=\sqrt[3]{27/8}\\r=3/2-1\\r=1/2=.5[/tex]
So, the interest rate is 50%.
the function y = a / x is given Which function will be obtained if the point P (-2,3) belongs to the graph of the given function
Answer:
The function is y = -6 / x.
Step-by-step explanation:
Since (-2, 3) belongs to the function, we know that x = -2, y = 3 is a solution to the function so when we plug those values in to solve for a, we get:
3 = a / (-2)
3 * (-2) = a / (-2) * (-2)
-6 = a so the function is y = -6 / x.

Answer:
-2
Step-by-step explanation:
The EASIEST way to do this is using the laws of the sum and products of roots.
When you multiply two roots together, you simply get c/a
So, let's start:
x^2 + x = 2
subtract the 2 to get a quadratic equation equal to 0
x^2 + x -2 =0
Now,
a=1
b=1
c=-2
plug b and a into c/a
-(2/1)= -(2) = -2
The answer is -2.
It's NOT 1. the answer would be 1 IF it was adding the roots.

write a equation of a line that has a slope of 5 and passes through the point (2,13)
Answer:
y = 5x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, thus
y = 5x + c ← is the partial equation
To find c substitute (2, 13) into the partial equation
13 = 10 + c ⇒ c = 13 - 10 = 3
y = 5x + 3 ← equation of line

What is the length of BC?
Answer:
The answer is option B2.1Step-by-step explanation:
To find the length of a we use the cosine rule
That's
a² = b² + c² - 2bc cos A
We have
a² = AB ² + AC ² - 2(AB)(AC) cos A
From the question
AB = 6
AC = 5
A = 20°
Substituting the values into the above formula we have
a² = 6² + 5² - 2(6)(5) cos 20
a² = 36 + 25 - 60cos 20
a² = 61 - 56.38
a² = 4.62
Find square root of both sides
a = √4.62
We have the final answer as
a = 2.1Hope this helps you
which one is irrational?
Basically everything but choice C
==========================================
Explanation:
sqrt is shorthand for square root
sqrt(4) = 2 = 2/1 showing that sqrt(4) is rational. We can write it as a fraction of two whole numbers, where 0 is not in the denominator.
-------
In contrast, we cannot write sqrt(2), sqrt(3), or sqrt(5) as a fraction of two whole numbers. Using your calculator, note how
sqrt(2) = 1.4142135623731
sqrt(3) = 1.73205080756888
sqrt(5) = 2.23606797749979
all of those decimal expansions go on forever without any pattern, which is a sign that those numbers are irrational. If they were rational, then a pattern would repeat at some point or the decimals would terminate at some point.
