Answer:
1. $8.30
Step-by-step explanation:
so 3 hats were purchased and each cost 15.50 so
15.50*3=46.50
and the rest of the 96.30 is 6 keychains so
96.30-46.50=49.80
and there is 6 keychains
49.80/6=8.30
Each key chain was $8.30
Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
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
Answer:
14 cm²
Step-by-step explanation:
Obtuse angle: more than 90° and less than 180°
The formula for the area of an obtuse triangle is the same as that for any triangle:
- area of a triangle = 1/2 x base x height
Therefore, given:
⇒ area = 1/2 x 4 x 7 = 14 cm²
The scientist stayed awake in class, so knows that the cosine of angle x is the ratio of y to the sun-moon distance. The sun-moon distance can be found by dividing y by the cosine of x.
