Answer:
x = 29°, y = 61°
Step-by-step explanation:
x + 61 = 90
Because of the right angle symbol
x = 90 - 61
x = 29°
x + y = 90
Because vertically opposite angles are equal
29 + y = 90
y = 90 - 29
y = 61°
Answer:
3937500
Step-by-step explanation:
People watched last year = x
if ratings were up 125% x increased by x and 25% of x
25% of 10.5 million is 2625000
x increased by itself and 2625000
x*2+2625000 = 10500000
cancel out 2625000 by subtracting to both sides
10500000 - 2625000 = 7875000
x*2 = 7875000
cancel out 2 by dividing 2 on both sides
7875000/2 = 3937500
x = 3937500
Answer:
it's the 2nd one
Step-by-step explanation:
d = 3 + at^2
-3 | -3
d - 3 = at^2
d - 3/a = t^2
√d - 3/a = √t^2
t = √d - 3/a
Answer:
2.3 × 
is 20,000 times greater than 1.15 × 
Step-by-step explanation:
Given as :
The first number= x = 2.3 ×
The second number= y = 1.15 ×
Let The first number is z times greater than second number
i.e x = z × y
Or, z = 
Or, z = 
Or, z = 2 × 
∴ z = 20,000
So,The first number is 20,000 times greater than second number
Hence, 2.3 × is 20,000 times greater than 1.15 × . Answer
Answer:
5/6
Step-by-step explanation:
Since 1/3÷2/5 can also be written as 1/3/2/5
So the ÷ can then be converted to × and 2/5 will change to 5/2
So let's solve
1/3×5/2
5/6
Since there is no common number that can divide the two
So the final answer is 5/6
