Answer:
93 ti the 24th power.
Step-by-step explanation:
when numbers w/ exponents are being multiplied and they are the same number just with different exponents you can add them up (the exponents). this is only for ×. with fractions you subtract.
Answer:
A
Step-by-step explanation:
To find how many times the distance, we divide the distance to the sun by the distance to the moon.
we get:
(9 * 10^7) / (2 * 10^5)
First, lets isolate and simplify the powers of 10.
(9 /2) * (10^7/10^5)
(9/2) * (10^2)=(9/2) * 100
Solve
9/2*100=4.5*100=450
The current lecture cost is $10
The current workshop costs $ 24
The current examination cost $60
The total cost for level one is (10+24+60)=$94
The cost of level 2 will be:
Lecture cost was increased by 20%, new cost will be:
120/100*10
=$12
The workshop cost was increased by 10 %, the new cost will be:
110/100*24=$26.4
The examination cost remained the same. The new total cost for stage 2 will be:
(12+26.4+60)=$98.4
Answer:
55,98,27
Step-by-step explanation:
To solve for the angles we must first find y with this equation
3y+5+2y-7=153
We can simplify this
5y-2=153
153+2=155
155/5=31
y=31
We now know y and can plug it into the angles
<A=2y-7
2(31)-7
62-7
55
<A=55
<B=3y+5
3(31)+5
93+5
98
<B=98
Now time for the last angle
Since angle BCA and DCB are next to each other they add up to 180
153+x=180
180-153=27
x=27
<BCA=27
Answer:
The probability of rain is 0.4.
Step-by-step explanation:
The given statement is “there is a 40% chance of rain tomorrow”.
There is a 40% chance of rain tomorrow, it means out of 100 the chances of rain is 40.
Therefore the probability of rain is 0.4.
