Answer:
15200cm^2
Step-by-step explanation:
we can separate this into 2 equivalent triangles , 2 equivalent rectangles, and 1 extra rectangle.
the area of a triangle is 1/2b*h so 40*60*1/2=1200
we have 2 of these triangles so the area of the triangles in total is 2400.
next, the 2 equivalent rectangles. the area of a rectangle is b*h is 80*50= 4000
we have 2 so the area of these rectangles in total is 8000.
lastly we have one more rectangle 60*80=4800.
then we add all these up 2400+8000+4800= 15200
add unit
15200cm^2
and we're done
Leila's fish tank has 18 liters of water in it. She plans to add 5 liters per minute until the tank has more than 58 liters. What are the possible numbers of minutes Leila could add water? Use t for the number of minutes.
Write your answer as an inequality solved for t.
58<18+5t
40<5t
8
JUST LIKE THIS U CAN SOLVE...
ITS BETTER TO NOT GIVE STRAIGHT ANSWERS
The solution to the answer is as follows:
-7^-1 = -1/7
The expression without an exponent would be simplified to be -1/7.

Answer:
0.6826
Step-by-step explanation:
Mean(μ) = 37
Standard deviation (σ) = 9
P(28 < x < 46) = ???
Using normal distribution
Z = (x - μ)/σ
For x = 28
Z = (28 - 37)/9
Z = -9/9
Z = -1
For x = 46
Z = (46 - 37)/9
Z = 9/9
Z = 1
We now have
P(-1 < Z < 1)
= P(Z < 1) - P(Z < -1)
From the table, Z = 1 = 0.3413
φ(Z) = 0.3413
Recall that
When Z is positive, P(x<a) = 0.5 +φ(Z)
P(Z<1)= 0.5 + 0.3413
= 0.8413
When Z is negative, P(x<a) = 0.5 - φ(Z)
P(Z< -1)= 0.5 - 0.3413
= 0.1587
We now have
0.8413 - 0.1587
= 0.6826
Answer:741
Step-by-step explanation:
Given
First term 
last term 
and no of terms 
And sum of n terms is given by
![S_n=\frac{n}{2}[a_1+a_n]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba_1%2Ba_n%5D)
![S_n=\frac{13}{2}[16+98]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7B13%7D%7B2%7D%5B16%2B98%5D)
Sp sum of n terms is 741
