Answer:
144 is the l.c.m of 16 and 18
explanation:
<u>multiples</u>:
16 - 16, 32, 48, 64, 80, 96, 112, 128, 144
18 - 18, 36, 54, 72, 90, 108, 126, 144
Therefore, 144 is the l.c.m of 16 and 18 which is divisible by both numbers.
Answer:
Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4
1) Multiply 12 by 4.1.
2) Divide 49.2 by 2.
3) Multiply 24.6 by 9.
Step-by-step explanation:
sin ∅ + 1 = cos2∅
From multiple angles in trigonometry
cos2∅ = 1 - 2sin²∅
So we have
sin∅ + 1 = 1 - 2sin²∅
sin∅ +1 - 1 + 2sin²∅= 0
sin∅ + 2sin²∅ = 0
Factor out sin∅
sin∅ ( 1 + 2sin∅) = 0
sin ∅ = 0
∅ = 0° , 180°
1 + 2sin∅ = 0
2sin∅ = - 1
sin ∅ = -1/2
∅ = 210° , 330°
The solutions are
<h3>0° , 180° , 210° , 330°</h3>

Given:
The actual length of side y is 22cm.
To find:
The length of side x by using the scale drawing.
Solution:
We know that the corresponding sides of original figure and scale drawing are proportional.
Therefore, the length of side x is about 28.286 cm.
Step-by-step explanation:
slope is the number before x so slope here is 3/1 always add the 1 if its a whole number if its a fraction leave it.
y=mx+b
the y-intercept is always be so graphing is now easy
put a dot on the y-intercept so in this case it is 3 on the y-axis. then use rise over run. rise being up and down and run being left and right. so go up 3 then right 1 and put a dot there and connect your 2 lines to make a graph. if the number was -3/1 you go down 3 and right one then but thats just hypothetical
now to make a equation for a point you put it in y=mx+b.
