Answer:
62 Kg
Step-by-step explanation:
Let g = weight of Grok last year in kg
m = weight of Grok's mother last year in kg
m = 3g
m-4 = 2(g+9)
since m = 3g
(3g)-4 = 2(g+9)
3g -4 = 2g + 18
3g-2g = 18+4
g = 22
m = 3*22
= 66
Note that:
g+9 = weight of Grok now
m-4 = weight of Grok's mother now
Grok weighs 31 Kg now
Grok's mother weighs 62 Kg now
Answer:
b. 10
Step-by-step explanation:
The triangles are all similar, so you have ...
hypotenuse/short side = x/4 = 25/x
Cross multiplying gives ...
x^2 = 100
x = 10 . . . . . . . take the square root
With a thermal camera, yes you can see farts, otherwise to the naked eye, it is impossible to see farts
Answer:
b, the y-intercept, is 1
Step-by-step explanation:
Compare the given y = 4x + 1 to
y = mx + b
We see immediately that b, the y-intercept, is 1.
The domain of a real function will be all the places where the denominator isn't zero and the radicand in the square root isn't negative.
So find the places where the denominator vanishes or the square root is of a negative number and exclude those places from the domain.
