Answer:
a. x = 12
b. x = 4
Step-by-step explanation:
a. RECTANGLE
ABCD is a rectangle, AC and BD are its diagonals.
Diagonals of a rectangle are congruent.
Therefore,
AC = BD
10x + 8 = 9x + 20
10x - 9x = 20 - 8
x = 12
b. RHOMBUS
Diagonal of a rectangle bisect opposite angles.
Therefore,
(5x + 3)° = (2x + 15)°
5x + 3 = 2x + 15
5x - 2x = 15 - 3
3x = 12
x = 12/3
x = 4
Answer:
Cereal B
Step-by-step explanation:
Given are two different rates for cereals A and B.
as Cereal A: 15oz for $2.95 or Cereal B: 32oz for $5.95
As such we cannot compare unless we make it unit rate for same number of units
Let us find unit oz rates
Cereal A per oz=
dollars
Cereal B per oz =
dollars
Comparing unit rates per ounce,
we find that Cereal B per oz is lower.
Answer is Cereal B.
Answer:
27300
Step-by-step explanation:
21%/100=0.21
Then I multiplied 0.21 with the total number of people
0.21*130000=27300
Try this answer.......
(click on the picture if you don't know what i am talking about)
so 24cm out of 300 cm is spliced
24/300 is the fraction
we can simplify this by dividing top and bottom by 3 to get
8/100
we can divide top and bottom by 4 to get
2/25 is the most simplified fraction
