Answer:
x=3 MT=36 MH=18
Step-by-step explanation:
The two triangles are the same, so 7x+8=10x-1
3x=9
x=3
MT=12x3=36
MH=36/2=18
Answer:
66 m²
Step-by-step explanation:
A = ½ (a + b) h
A = ½ (10 + 12) (6)
A = 66
The area is 66 m².
Answer:
Step-by-step explanation:
The area of a sector has the formula
Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:
and simplifying that a bit to look less threatening, but not by much:
and
Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
Answer:
log(x^7·y^2)
Step-by-step explanation:
The applicable rules are ...
... log(a^b) = b·log(a)
... log(ab) = log(a) +log(b)
_____
The first term, 7log(x) can be rewritten as log(x^7). Note that an exponentiation operator is needed when this is written as text.
The second term 2log(y) can be rewritten as log(y^2). These two rewrites make use of the first rule above.
Now, you have the sum ...
... log(x^7) +log(y^2)
The second rule tells you this can be rewritten as ...
... log(x^7·y^2) . . . . . seems to match the intent of the 3rd selection
$20 a month. if u subtract the amount that she started with from $85, you get $60. $60 divided by 3 months is $20 a month
