Answer:
70
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
x = 30+40
x = 70
If a secant and a tangent of a circle are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment.
y² = 7(15+7)
y² = 7*22
y² = 154
y = √154
y = 12.4 to the nearest tenth
Answer:
The required equation is
Charges = $(22 * No of Rooms cleaned)
Step-by-step explanation:
Direct Relation:
The relation ship in which if one quantity increase then it results in the increase of the other quantity too and if it decreases then other quantity will decrease too.
it is represented by
a∝b
a= kb
where k is constant of proportionality
Now for the given question
Charges is directly proportional to no of rooms cleaned
It is
Charges ∝ No of rooms cleaned
It could be written as
Charges = K * No of rooms cleaned
Here k is given as $22 for each room
so
it becomes
Charges = $(22 * No of Rooms cleaned)
which is the relationship in form of equation!!!
Answer:
2 21/40
Step-by-step explanation:
First, you take the fractions in the parenthesis and make the denominators alike by finding the least common multiple. Once you've done that you can add them together and then add the outer fraction. When adding the outer fraction, you need to make it into an improper fraction. I hope this helped! :)
