A "straight angle" is a straight line.
The angle of a straight line is 180 degrees.
The value of 2 angles add together to make 180
One of the angles = 89 degrees
The value of the second angle = 180-89 = 91
Answer:
11/10
Step-by-step explanation:
4/5 = 8/10
8/10 + 3/10 = 11/10 or 1 and 1/10
Answer:
All of the angles
Step-by-step explanation:
All of the angles
1) The sum of 2 prime numbers is ALWAYS even, so if x and y are prime number,. then (x+y)/7 = z². In this case either x = 2 or y = 5 (or vice vera). This is the only possibility to be divisible by 7 . Then (5+2)/7 = 1² = 1
2) 5 pipes → 2 hours → 2 pools
then 1 pipe takes (5x2) 10 hours to fill 2 pools
or 1 pipe takes (10/2) 5 hours to fill 1 pool
3) It's 6/30 = 0.2 or 20%
4) 35% represent 7 Students, 100% of the class represent x students:
35%/7 = 100%/x
0.35/7 = 1/x (Cross multiplication) →0.35x = 7 and x = 7/0.35 → x = 20 students
5) Let K be the age of Katie and B her brother's
K + 2 = B OR K = x - 2 (Today)
In 12 years (B+12), B will be twice K (remember K = B-2) →
B+12 = 2(K) OR B+12 = 2(B-2)
B+12 = 2(B-2) →
B+12 = 2B - 4→
12 + 4 = B and B = 16. If the brother is 16, then Kate is 14

Answer:
The person should pay <u>2 3/16</u> dollars
Step-by-step explanation:
Let us revise how to multiply a mixed number by a proper fraction
Change the mixed number to improper fraction by multiplying the whole number by the denominator and ad the the product to the numerator and put the sum over the denominator.
Multiply the two numerators and multiply the two denominators.
One yard of a rubber coat costs 3 1/2 dollars.
We need to find the cost of 5/8 yards.
- Multiply the cost of 1 yard by 5/8
3 1/2=7/2
The cost = 7/2×5/8=35/16
Change the improper fraction to a mixed number
35/16=2 3/16
∴ The cost =2 3/16 dollars
