Sushil Sushil and his sister share a study table. The top of the table has a length of 90 90 cm cm and a breadth of 80 80 cm cm . If each person uses half of the table, how much space does Sushil Sushil use?
Answer:
3600cm^2
Step-by-step explanation:
length (l)= 90cm
breath (b)=80cm
Area of table(A)= l×b
= 90×80
=7200cm^2
Half of the table= Area of table/2
=7200/2
=3600cm^2

The recipe says he needs 450 grams of rice for 6 people
how many kilograms of rice will he need for 18
Answer:
1.35kg
Step-by-step explanation:
450g : 6 people
x : 18 people
To get from 6 to 18, multiply by 3 so do the same to the other side
450 × 3 = 1350g
To convert from g to kg divide by 1000
1350 ÷ 1000 = 1.35kg

You should study the exponential laws. Remember that (a/b) to the exponent of m is the same as a to the exponent of m over b to the exponent of m.
Therefore, 2 to the exponent of 5×4 over 3 to the exponent of 2×4 equals to 1048576/6561.

The class scores of a history test have a normal distribution with a mean Mu = 79 and a standard deviation Sigma = 7. If Opal’s test score was 72, which expression would she write to find the z-score of her test score? z = StartFraction 72 minus 79 Over 7 EndFraction z = StartFraction 72 minus 7 Over 7 EndFraction z = StartFraction 79 minus 72 Over 7 EndFraction z = StartFraction 7 minus 79 Over 7 EndFraction.
The value of z score for the history class test of Opal’s test score is negative one (-1).
What is normally distributed data?Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The z score for the normal distributed data can be given as,
[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]
The mean value of the scores of history class is,
[tex]\mu=79[/tex]
The standard deviation value of the scores of history class is,
[tex]\sigma=7[/tex]
Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,
[tex]z=\dfrac{72-79}{7}\\z=-1[/tex]
Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).

Help me with my math and please try to explain it step by step!
========================================================
Explanation:
r = radius of the circle = 3
This is because segment IJ is 3 units.
Let's find the area of a full circle based on this radius.
A = pi*r^2
A = pi*3^2
A = 9pi
That's the area of a full circle with radius 3.
However, we only have a small pizza slice shaded. This slice has area of (1/2)pi or pi/2
If we divided the area of the slice over the full area, then we can figure out how many equal such slices make up the full circle.
(9pi)/(pi/2) = 9pi*(2/pi) = 18
This pizza has 18 slices total. Each slice has area pi/2 and it gives a total area of 18*(pi/2) = 9pi
The jump from pi/2 to 9pi is exactly "times 18" to represent the 18 slices.
--------------------
Since we now know that this pizza has 18 equal slices, we'll cut a full 360 degree rotation into 18 equal pieces
360/18 = 20
Therefore, the central angle KIJ is 20 degrees.
Plug this central angle, along with the radius, into the arc length formula
L = arc length
L = (circumference)*(angle in degrees)/360
L = (2*pi*r)*(20/360)
L = 2pi*9*(1/18)
L = pi
Arc KJ is exactly pi units long.
--------------------
Paraphrased another way:
The full distance around the circle is 2*pi*r = 2*pi*9 = 18pi units
However, we only want a slice of this perimeter. We divide by 18 because we found earlier that there are 18 equal slices.
So each slice has its curved portion, aka arc length, being (18pi)/18 = pi units
Explain why the polynomial 144x2 − 200x + 81 is not a perfect square.
Answer: It's not
Step-by-step explanation:
A perfect square is always [tex](x+y)^{2}[/tex], where [tex]x^{2} +2xy+y^{2}[/tex].
Knowing this, we can square root 144x to get 12x. Square rooting 81 gets us 9. Unfortunately, if we multiply 12 and 9 together, then double it, we get 216, which is definitely not 200.
Therefore, the polynomial is not a perfect square.

Factor the denominator
Answer:
B. (x+4)(x-4)
Step-by-step explanation:
We are given:
[tex]y=\frac{2x}{x^2-16}[/tex]
And asked to factor the denominator.
When factoring, you have a^2 + bx + c, and when wanting to turn it into a binomial, you have to find two numbers that multiply to c and add up to b.
In this case, we see that c is equal to -16. List out the factor of -16:
±1 , ±16
±2 , ±8
-4 , 4
Now we see that b is not present, therefore being 0. Our goal is to find two factors of -16 that will equal to 0 when added.
1 and 16 will never make 0
2 and 8 cannot make 0 either
4 and 4 can make 0, and since 16 is a negative number, one 4 needs to be negative while the other is a positive.
Basically stating, our factor of the denominator is:
[(x + 4)(x - 4)]
