Answer:
1222
Step-by-step explanation:
312/12 = 26
So, you have to multiply y (47) by 26
This will get you 1222
Answer:
the sides of the triangle are 4 cm , 8 cm , 20 cm
Answer:
length = 6 yards
width = 3.5 yards
Step-by-step explanation:
the length of a rectangle is 1 yard less than twice the width
LEt 'w' be the width of the rectangle
and 'l' be the length of the rectangle
length l = 2 times the width -1
so l = 2w -1
Area of the rectangle = length * width
Area = l * w
we know length is 2w-1 and given area = 21
21 = (2w-1) * w

subtract 21 on both sides

now solve for 'w'

0 = 2w(w+3)-7(w+3)
0= (2w-7)(w+3)
2w-7 = 0 and w+3 =0
w = 7/2 w=-3
width cannot be negative so we ignore w=-3
width w= 3.5
length = 2w-1= 2(3.5) - 1= 7-1=6
length = 6 yards
Answer:
80.
Step-by-step explanation:
Three digit number can only have three patterns
A. All digits are distinct
B. Two digits are same and third is different
C. All three digits are alike.
We need to calculate B
that is B= Total- A-C
Total numbers from 700 to 999= 299.
Number numbers having all digits distinct = 3×9×8= 216 ( first digit can have only three digits 7,8,9)
All three are alike = 3 ( 777,888,999).
So, 299 -216-3= 80.
There is a 2/9 chance that both marbles drawn will be blue.
