Answer:
x = 4.98
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 50 = x/6.5
6.5 sin 50 =x
x=4.97928
x = 4.98
Answer:
Solution given:
ratio of boys to the girls=5:3
let ratio be 5x and 3x
we have
5x+3x=40
8x=40
x=40/8
x=5
5x=5*5=25
3x=3*5=15

No of boys=25
No of girls=15
828 small spheres can be made from the metal.
Step-by-step explanation:
Side of the cube = 4.5cm
Volume = (a x a x a)
= (4.5 x 4.5 x 4.5)
= 91.125 cubic cm
Radius of the sphere = 3mm = 0.3 cm
Volume of 1 sphere = (4/3) π(r x r x r)
= (4/3) (3.14) (0.3 x 0.3 x 0.3)
= (4/3) (3.14) (0.027)
= 0.34/3
= 0.11 cubic cm
No. of spheres = 91.125/0.11
= 828.4
So, 828 small spheres can be made from the metal.
The answer is "She can do either one first because zero pairs will be created to isolate the variable either way."
Yo, im doing the same CR right now. haha
I think i have an idea on what to do.
triangles have to equal 180 degrees.
if A = 45
and C = 60
then B = 75
45 + 60 + 75 = 180.
it says the ABC is SIMILAR to XYZ.
I think they are both congruent, so ABC and XYZ have the same measurements.
that means is B = 75
then Y = 75.
i could be wrong, but thats what i think the answer would be.
