Answer: 174 red chips
Step-by-step explanation:
A bag contains a total of 300 red chips and white chips. A student chooses a chip out of the bag, then records the color, and places the chip back in the bag. By doing this, the student recorded 29 red chips and 21 white chips.
To predict the number of red chips in the bag using this method goes thus:
Number of red chips picked= 29
Number of white chips picked= 21
Total number of chips= 29+21 = 50
So, the student picked 29/50. Out of 300 chips, number of reds that will be picked will be:
= 29/50 × 300
= 29 × 6
= 174 red chips
Answer:
x=45.5
Step-by-step explanation:
sum of angles of a quadrilateral is 360°
so 3x - 11+x+8+x-8+2x+7+x=360°
or 8x-4=360
or, x=364÷8
hence
x=45.5
Answer: option c
length = 9m
Perimeter = 26.4m
Step-by-step explanation:
A rectangle has a width of 4.2 m and an area of 37.8 m^2
We want yo determine the length of the rectangle and the perimeter of the rectangle.
The perimeter of the rectangle is the distance round the shape. Let the width of the triangle be w.
The perimeter of the rectangle would be expressed as Length + width + length + width. This becomes
2(length +width). So the perimeter of the given rectangle is
2(length + 4.2) but the area is given as 37.8 m^2. Area of a rectangle is length × width. It becomes
37.8= length × 4.2
Length = 37.8/4.2 = 9m
Therefore, the perimeter is
2(length + 4.2) = 2(9+4.2)
Perimeter = 2× 13.2 = 26.4m
