Answer:
C5
Step-by-step explanation: 10 x 2 = 20 so you add the 2 to the other one and get 4. Then half of 10 is 5 and half of 2 is 1, so add 1 to 4 and your answer is 5.
10x2= 20 +5= 25 Answer:5
Answer:
This question is not as hard as it seems.
Let the first number = x.
The other number will be x - 16.
The sum of both the number is 52.
So, x+x-16 = 52
Which would simplify to 2x -16 = 52.
When I add 16 to both sides, it would give me 2x = 68.
Then, divide both sides by 2.
This leaves us with x = 34.
Since we have x, now x-16 would be 34-16 = 18.
The two numbers are 34 and 18, this answer is correct because both of them add up to give me 52.

Answer:
Step-by-step explanation:
base=42 m
height=h=?
base angle θ=60°
tan 60=h/42
h=42tan 60=42√3≈72.75 m
height of taller building=135+42√3 m≈135+72.75≈207.75 m≈208 m
Answer: 0.790
Step-by-step explanation:
Given : The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.
The sample size : n= 2004
The number of students read above the eighth grade level = 1584
Then , the proportion of students read above the eighth grade level is given by :-
Hence, the estimate proportion of tenth graders reading at or below the eighth grade level =0.790
