Answer:
B
Step-by-step explanation:
the key says the solid black dots are negative numbers
there is 3 of them
(-3)
the white dots are normal numbers
there are 5
they are being added together
5+(-3)
5-3
2
its B
also, you are so lucky its only 72F where you live I am so hot here it is like 98.
Answer:
45 C is 113 F
Step-by-step explanation:
45° C
The temperature is given in 45° C.
To convert into degree Fahrenheit first multiply 45 by 9 and we get 405.
Then, divide 405 by 5 we get 81.
lastly we need to add 32 and 81 we get 113.
Therefore, 45° C = 113° F
Really Really Hot
A/c = 8.....a = 8c
a * c = 2 ...a = 2/c
a/b = -16 ...a = -16b
a * b = -1....
b/c = -0.5
2/c = 8c
2 = 8c^2
1/4 = c^2
sqrt 1/4 = c
0.5 (or 1/2) = c <===
a * c = 2
0.5a = 2
a = 2/0.5
a = 4 <===
a = -16b
4 = -16b
4/-16 = b
-1/4 (or - 0.25) = b <===
√(80)=√(4*20)=√(4*4*5)=4√5
