Find the area of each figure
Answers
Answer:
1824in. 2
Step-by-step explanation:
first, we need to cut it to two figure (a triangle and a rectangle), then calculate each of the area.
the area of triangle
= 12in.×48in.×1/2
= 576in.2×1/2
= 288in.2
the area of rectangle
= 32in.×48in.
= 1536in.2
the area
= 288in.2+1536in.2
= 1824in.2
The perimeter of a square is (8x + 6) centimeters. Part A: Write an expression for the length of a side of the square. Part B: The perimeter of the square is 72 centimeters. Write and solve an equation to find the value of x, then find the side length of the square.
Answers
Step-by-step explanation:
Part A:
(8x+6)/4= 2x+ 1.5
Part B:
72= (8x+6)
8x= 72-6
8x= 66
x= 8.25
the side length = 2x+1.5= 2(8.25)+1.5= 18 centimetres
Daniel says that more than half the students spent 2 1 2 hours or more on homework. Liz says more than half the students spent less than 2 1 2 hours on homework. Who is correct? Explain.
Answers
Answer:
Liz is correct
Step-by-step explanation:
Given
See attachment for complete question
Required
Who is correct? Daniel or Liz
From the attached data, we have:
[tex]Time: 1\frac{3}{4},\ 2\frac{1}{2},\ 2,\ 2\frac{3}{4},\ 1,\ 1\frac{3}{4},\ 1\frac{1}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4},\ 2,\ 2[/tex]
The total number of students is:
[tex]n = 12[/tex]
The data that represents [tex]2\frac{1}{2}[/tex] or more is:
[tex]Time: 2\frac{1}{2},\ 2\frac{3}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4}[/tex]
The frequency of this is 5
The frequency that represents [tex]2\frac{1}{2}[/tex] or less will be 7
This means that less than half spend [tex]2\frac{1}{2}[/tex] or more
and more than half spend [tex]2\frac{1}{2}[/tex] or more
Hence, Daniel is incorrect. Liz is correct

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Yellow crayon- 2/8 = 1/4 because there are 2 yellow out of a total 8. If we simplify that and divide 2 from both sides, we get 1/4. :) Hope that helps! <3
