This question requires you to know the lowest common multiple (LCM) of 5, 4 and 2. there are a few ways to do that. in this case the LCM would be 20. this means that in 20 year the science department would buy all 3 equipment at the same time
4 , 7 , 14 , 19 , 21 , 23 , 23 , 26 , 27 , 30

HOPE IT'S HELP ;)
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A

: It looks like this in the calculator

× cos A=

(0.6489)
(

and cos cancels out)
A=

(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Answer:
F. Isosceles acute
Step-by-step explanation:
Looking at the image provided, you can see that there are two congruent angles (50 degrees) and the two congruent sides (5.26), making the triangles isosceles.
An isosceles triangle is when there are two congruent sides.
Next, by looking at the angle measurements, you can determine that the triangle is acute because the angles are all below the degree of 90.
An acute triangle is when all the angles are below the degree of 90, but still add up together to make a degree of 180.
Answer:
$345
Step-by-step explanation:
$69 a day for 5 days that means 69 x 5 then that’s $345 hope this helps
