We know that an isosceles triangle has 2 equal sides.
We can represent the equal sides with x, and the base with y:
2x + y = 15.6
Given states that y = x - 3, so:
2x + x - 3 = 15.6
3x = 18.6
x = 6.2
y = 3.2
The sides are 6.2 m, and the base is 3.2 m.
Answer:
The answer is 9.72 .
Step-by-step explanation:
You can do it by elaborating :
2.43×4 = (2.00×4) + (0.4×4) + (0.03×4)
= 8.00 + 1.6 + 0.12
= 9.72
Answer:
4n+20
Step-by-step explanation:
Let Tina bought X number of nail polish any Y number of lip gloss.
then, X+Y=9
or,X=9-Y
Also,4.5 X+7 Y=50.5
or, 4.5 (9-Y) +7 Y=50.5
or, Y =4.........................................(i)
so, X= 9-4
= 5........................................(ii)
hence, she bought 5 nail polish and 4 lip gloss
Answer:
The correct option is - D.
Step-by-step explanation:
To find - Select the correct answer. The parent tangent function is transformed such that its period is halved. Which graph could represent the transformed function?
Solution -
We know that,
The parent tangent function is -
f(x) = tan(x)
Period of Parent function = 
Now,
If Period is half,
Then
The function is transformed to
f(x) = tan(2x)
So,
The graph becomes
The correct option is - D.
