Step-by-step explanation:
by using Pythagoras theorem,
h^2= p^2+b^2
or, b^2=h^2- p^2
Answer:
74 degrees because E is alternate interior angles with the other 74 degrees angle.
Step-by-step explanation:
An equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 will be −5x − 7 > −22 and −5x − 7 ≥ −33
<h3>Compound inequality</h3>
A compound inequality (or combined inequality ) is two or more inequalities joined together with inequality operations.
Given the compound inequality −22 > −5x − 7 ≥ −33, this can also be splitted into;
−22 > −5x − 7 and −5x − 7 ≥ −33,
The inequality expression −22 > −5x − 7 is also expressed as −5x − 7 > -22. Hence an equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 will be −5x − 7 > −22 and −5x − 7 ≥ −33

#SPJ1
Answer:
50 soldiers must be transferred elsewhere.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
As the number of soldiers decrease, the provisions last for more time. This means that the measures are inversely proportional, and we have an inverse rule of three, using line multiplication, instead of cross.
30 days of provisions - 200 soldiers
40 days of provisions - x soldiers
Simplifying by 40
The provisions will last for 40 days with 150 soldiers, which means that 200 - 150 = 50 soldiers must be transferred elsewhere.
Answer:
3 -12i
Step-by-step explanation:
(-6-8i)-(-9+4i)
distribute the minus sign
-6 -8i +9 -4i
combine like terms
-6+9 -8i -4i
3 -12i
