Answer:
assume both unknown angles as x so x+x=2x
then 180° (2x+90)=90/2
angle x =45°
another angle = 180-[90°+45°]
. 180°-135°
=45°
so angle x =45°
another angle = 45°
Answer:
Step-by-step explanation:
-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
88 % students of the class hand in their projects on time
<em><u>Solution:</u></em>
Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time
Total number students = 25
Students hand in their projects on time = 22
<em><u>To find: percent of the class hand in their projects on time</u></em>
Substituting the values, we get
Thus 88 % students of the class hand in their projects on time
If we say that the weight of Jill's cat is w, then we can say that the weight of Jack's cat is 4w.
We know that the combined weight is 35 pounds, so we can write this as
4w+w=35
Which simplifies to
5w=35
If we divide by 5, we are left with
w=7
So that gives us the weight of Jill's cat. If Jack's cat weighs 4 times as much, we can see that
4x7=28
Therefore, Jack's cat weighs 28 pounds :)
