Peter made a rectangular sandbox for his brother to play in. The sand box measured 4 feet by 5 feet by 1 One-half feet. How much sand will fill the sandbox?
A: 30 ft2
B: 30 ft3
C: 67 ft2
D: 67 ft3
Answers
we need to find the volume of the box, so we have to multiply the 4x5x1.5. That equals 30. Since we multiply 3 different quantities of feet together, the unit is ft cubed, so the answer is b 30ft3.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

A local college wants to determine student interest in athletics and in academic clubs. The college surveys a random group of students, and the results of the survey are described below.

Total

240
Explanation:
From the information given, we know that 35% of the 240 students surveyed were interested in athletics, which means 0.35 x 240 = 84 students were interested in athletics. We also know that 3/5 of the students were interested in academic clubs, which means 3/5 x 240 = 144 students were interested in academic clubs.
We are also given that a total of 26 students were interested in both athletics and academic clubs, which means this number should go in the cell that represents the intersection of the "Interested in Athletics" column and the "Interested in Academic Clubs" row.
To fill in the remaining blanks, we can use the following relationships:
The total number of students interested in athletics is 84, which means the number of students who are interested in athletics but not academic clubs is 84 - 26 = 58. This goes in the cell that represents the intersection of the "Interested in Athletics" column and the "Not Interested in Academic Clubs" row.
The total number of students interested in academic clubs is 144, which means the number of students who are interested in academic clubs but not athletics is 144 - 26 = 118. This goes in the cell that represents the intersection of the "Not Interested in Athletics" column and the "Interested in Academic Clubs" row.
The total number of students who are not interested in athletics is 240 - 84 = 156, which means the number of students who are not interested in athletics or academic clubs is 156 - 38 = 118. This goes in the cell that represents the intersection of the "Not Interested in Athletics" column and the "Not Interested in Academic Clubs" row.
Finally, we can calculate the total number of students who are not interested in academic clubs by subtracting the number of students interested in academic clubs (144) from the total number of students (240), which gives us 240 - 144 = 96. This goes in the cell that represents the intersection of the "Interested in Athletics" column and the "Not Interested in Academic Clubs" row.

What is the perimeter of the triangle below
Answers
Answer:
P = 36 inches
Step-by-step explanation:
To find the perimeter of the triangle, add up all the sides.
P = s1 + s2+ s3
P = 13+13+10
P = 36 inches
Answer: The perimeter of the triangle is 36 inches. The correct option is d
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the length of all sides of the triangle. This is an isosceles triangle. This means that the length of two sides out of three of the shape have the same length.
In such a triangle, the two equal sides are called the arms. The other side, represented usually as the lowermost, is called the base. The formula to find the perimeter of any isosceles triangle is-
Perimeter=(arm length)*2+base length
Therefore-
Perimeter=(13 inches)*2+10inches=36

Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
