Answer:
The Ross family used it for 15 hours
The Watson family used it for 20 hours
Step-by-step explanation:
We can rewrite this word problem using variables.
[tex](x*40)+(y*20)=1000[/tex] and [tex]x+y=35[/tex]
Now we can split 35 between x and y. Since 35 can't be split into a whole number, I have split it into 17 and 18
(17*40) + (18*20) = 1040
This is close but 40 too much. Since this is 40 off, we need to move 2 more hours to the Watson family.
(15*40) + (20*20) = 1000
This means -
The Ross family used it for 15 hours
The Watson family used it for 20 hours
What is the volume of the composite solid? 6 m 4 m 3 m 4 m 4 m
Answer:
Please read explanation
Step-by-step explanation:
A picture would be helpful, but I think the answer might be (6x4x3)+(3x4x4). If your shape is made up of many parts, you should find the volume of each shape then add them up to find the total volume. (To find volume, multiply base x height x width) If you could give a picture, it would be very helpful because I don't really know which numbers I should multiply to find volume. I hope this explanation helps, and please comment if you need to ask me anything.

Which of the following cannot be solved using nPr?
permutations of the letters of the word "OF"
permutations of the letters of the word "PERMUTATION"
permutations of the letters of the word "THINGS"
permutations of the letters of the word "N"
Answer:
permutations of the letters of the word "PERMUTATION"
Step-by-step explanation:
The number of permutations of the letters of the word "PERMUTATION" cannot be solved using nPr. The correct answer is B.
What is the permutation?The permutation is defined as considered an ordered combination.
The following formula computes the permutation of r items from n:
P(n, r) = n! /(n-r)!
here order matters and repetition is not allowed.
Therefore, nPr cannot be used to solve problems that involve repeating items or where order does not matter.
As per the question, the permutations of the letters of the word "OF", "THINGS", and "N" involve distinct letters and no repetition, so they can be solved using nPr.
However, the word "PERMUTATION" has repeated letters.
Therefore, the number of permutations of the letters of the word "PERMUTATION" cannot be solved using nPr because it does not account for repeated items.

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=83°, and RS = 7 feet. Find the length of SQ to the nearest tenth of a foot.
Answer:
x ~0.9
Step-by-step explanation:
To solve for (x) in the given right triangle, use the trigonometric ratios, which are the following,
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
Each of the sides of a triangle is named with respect to the given angle. In this problem, one is given the side opposite to the given angle, and the side adjacent to it. Use the ratio of tangent (tan) to solve for the unknown side.
[tex]tan(83)=\frac{7}{x}[/tex]
Manipulate the equation so that it is solved for (x),
[tex]x=\frac{7}{tan(83)}[/tex]

The area of the figure is ___ square units.
Answer:
26 square units
Step-by-step explanation:
We are given a diagram and are asked to find the area of the figure in square units.
To solve, take in mind that we need to multiply the sides given.
Area is L * W, therefore, we know that our length is 5 by 2 units, while our width is 3 by 2 units.
First start with the length, since it is 5 by 2 we multiply 5 and 2 :
5 * 2 = 10
Then with the width, since it is 3 by 2, we can multiply 3 and 2 :
3 * 2 = 6
Then do the length again since the bottom part of the diagram needs to be included, it is also 5 by 2 :
5 * 2 = 10
Add all these together to get your answer :
10 + 6 + 10
16 + 10
26 square units.
