Answer:
area= 1/2*(h*b) h- height, b- base
the triangle is isosceles (denoted by the 2 dashes on the sides of the triangle)
so they are equal in length
angles in triangle = 180
so 38+38=76
180-76=104
base=24
divide the triangle in the center
so now triangle 1(left) the base = 12
and triangle 2(right) the base = 12
use trigonometric ratios
in this we need to find the height
which is opposite of 38,
we already have the adjacent =12
so the ratio is Tan (Tangent Opposite/Adjacent)(TOA)
Tan38= (12/h)
multiply by h
h*Tan38=12
h=12/tan38 = 15.35929959
OK so 80% of 8,200=6560
8,200-6560= 1,640
He lost 1,640
Answer:
True
Step-by-step explanation:
Both happened in different times and are seprate events
Answer:
first answer is correct
Step-by-step explanation:
Hello, we want to write 2 + 4 + 6 + ... + 20
for n = 1, 2n = 2*1 =2
for n = 2, 2n = 2*2=4
for n = 3, 2n=2*3=6
etc
so

thanks
When you're adding fractions with two different denominators, the best thing to do is to find a common denominator;
In this case, 4 and 8 are both multiples of 8, and therefore, you've got to double the first fraction.
Doubling the first fraction gives you 2/8 and 3/8. You've then got to add these together, and this gives you 5/8 (as you only add the numerators)
As you're looking for what is left, you have to do 8/8- 5/8 (once again, only subtracting the numerators)
8/8- 5/8= 3/8
Therefore, 3/8 of the muffins are left.
Hope this helps :)
