PQ is a radius. QS is tangent to the circle. In this scenario (a radius and a tangent passing through the same point of the radius) the two segments are always perpendicular.

This implies that PQS is a right triangle. We know that PQ = 10 because it's a radius.

Also, we have

$PS=PR+RS = 10+16 = 26$

because PR is a radius and RS is given.

So, we can derive QS using the pythagorean theorem:

$QS = \sqrt{PS^2-PQ^2} = \sqrt{676-100} = \sqrt{576} = 24$

The point is plotted on the number line.What whole number best approximates the value of x?

sattari [20]

You can eliminate 81 because we know $\sqrt{81} =9$

The dot is on approximately 9.32 (my estimate) so I would square that number:

(9.32)² = 86.8624 so if you round this you get 87

Mrs. Smith washed 2 5 of her laundry. Her son washed 1 3 of it. Who washed most of the laundry? How much of the laundry still ne

Tju [1.3M]

Answer:

a) The person who washed the most of the laundry is Mrs Smith

b) 4/15 of the laundry is left to wash

Step-by-step explanation:

Mrs. Smith washed 2/5 of her laundry. Her son washed 1/3 of it.

a) Who washed most of the laundry?

We convert the fraction of laundry each person washed to decimal

Mrs Smith = 2/5 = 0.4

Her son = 1/3 = 0.333

Therefore, the person who washed the most of the laundry is Mrs Smith

b) How much of the laundry still needs to be washed?

Let us total laundry = 1

=1 - ( 2/5 + 1/3)

Lowest Common Denominator is 15

=1- (3 × 2 + 5 × 1/15)

= 1 - (6 +5/15)

=1 - 11/15

= 4/15
