So 12% of a number is $75
12% of x is 75
0.12 of x is 75
0.12 * x = 75
divide both numbers by 0.12
x = 625
To check:
12% of 625 =?= 75
75 = 75
Hope this helps
Answer:
It is b^6
Step-by-step explanation:
Step-by-step explanation:
Since AB=I, we have
det(A)det(B)=det(AB)=det(I)=1.
This implies that the determinants det(A) and det(B) are not zero.
Hence A,B are invertible matrices: A−1,B−1 exist.
Now we compute
I=BB−1=BIB−1=B(AB)B−1=BAI=BA.since AB=I
Hence we obtain BA=I.
Since AB=I and BA=I, we conclude that B=A−1.
Answer:
20 people
Step-by-step explanation:
The volume of a cuboid is equal to length * breadth * height.
First, we want to figure out the values relative to each other. Everything is in centimeters except the breadth, which is 0.07m. To convert meters to centimeters, we can multiply by 100: 0.07 * 100 = 7, so the breadth is 7cm.
Next, the volume is length * breadth * height = 5cm * 7cm * 8cm = 280cm³. Each person occupies 14cm³. To find how many people can occupy the cube, we can divide the volume by the space each person takes, so
280cm³/14cm³ = 20 people
Note that we can divide because each person takes x amount of space, and the total space, z, can be represented by x * y = z, with y representing the amount of people, because we add x space for each person. Dividing both sides by x, we get y = z/x
Answer:
Step-by-step explanation:
S = (n - 2).180°
n = quantity of sides
S = all angles addition
S = (5 - 2).180°
S = 3.180°
S = 540°
104 + 117 + 100 + 124 + x = 540
445 + x = 540
x = 540 - 445
x = 95°
I hope I've helped you.
