Answer:
POOOOOOOOOOP KAKAKAKA
Step-by-step explanation:
This is the concept of geometry, given that the angle 52 and (2x) have been subtended by a circle, then:
2x=2(52)
2x=104
solving for x we get:
x=104/2
x=52
the answer is x=52°
Answer:
A
Step-by-step explanation:
From the graph, we can see that the <em>temperature increased initially</em>, then <em>started to decrease</em>. <u>All of these NOT in a constant rate, though</u>.
Roughly, the temperature was increasing from start till around 5.5 hours. Then on the temperature decreased.
So we can eliminate B, C, and D. That leaves us with correct answer as A.
Answer:
See below.
Step-by-step explanation:
To calculate a percentage divide by the part by the whole, You will get a decimal. The decimal becomes a percentage after you multiply by 100. This moves the decimal place two places to the right. So 0.10 becomes 10%.
1. 20 is 50% of 40 since 20/40 = 0.5
2. 8/ 32 = 0.25 so it is 25%
3. 2/40 = 1/20 = 0.05 so it is 5%
4. 100/25 = 4 so it is 400%
5. 3/ 2 = 1.5 so 150%
To find a percentage of a number, multiply the number by the decimal conversion of the percent.
6. 0.15(300) = 45
7. 33/75 = 0.44 so it is 44%
8. 12/18 = 2/3 = 0.66 so it is 66%
9. 0.35(1000) = 350
10. 40 is 20% of what can be solved by remembering that 20* 5 = 100%. So 5*40 = 200. The number is 200.
