Answer:

B: 8

Step-by-step explanation:

we are given two numbers which we can use to help solve this problem

A: the number of hours the dishwasher is being used

B: how long it takes the dishwasher to do each load

using this info we can find how many loads were washed in 10 hours by dividing the time it takes for each load by how many hours were spent.

10 / 1.25 = 8

A jar has 15 marbles: 4 are green, 6 are red, and 5 are yellow. What is the probability that we will get a red marble or the gre
Crank

2/3

There are 4 green marbles and 6 red marbles, making 10 green or red marbles.  The probability of drawing a red or a green marble is then 10/15 total marbles, which can be simplified to 2/3 by dividing the numerator and denominator each by 5.

Given: △FKL, FK=a, m∠F=45°, m∠L=30° Find: FL
drek231 [11]

The best way to do this is to draw a picture of ΔFKL and include line segment KM that is perpendicular to FL.  This creates ΔFKM which is a 45°-45°-90° triangle and ΔLKM which is a 30°-60°-90° triangle.

Find the lengths of FM and ML.  Then, FM + ML = FL

<u>FM</u>

ΔFKM (45°-45°-90°): FK is the hypotenuse so FM = \frac{a}{\sqrt{2}} = \frac{a\sqrt{2} }{2}

<u>ML</u>

ΔLKM (30°-60°-90°): from ΔFKM, we know that KM = \frac{a\sqrt{2} }{2} , so KL = \frac{a}{\sqrt{6}} = \frac{a\sqrt{6} }{6}  

<u>FM + ML = FL</u>

(\frac{3}{3})\frac{a\sqrt{2}  }{2} + \frac{a\sqrt{6}  }{6}

= \frac{3a\sqrt{2} + a\sqrt{6} }{6}

Write the ratio as a ratio of whole numbers using fractional notation 15 hours to 40 hours simplified fraction
Contact [7]

Answer:

3/8

Step-by-step explanation:

Since it is 15/40 hours originally, what we need to do is just simplify this fraction.

The numerator and denominator are both divisible by 5.
