Answer: 2400000
You can think of this as 6 x 4 = 24 then because there are 5 zeros in the equation you just have to add 5 zeros to the end!
I hope this helped!

in a school of 940 pupils, the number of girls exceeds the number of boys by 150. how many girls are there
Answer:
number of girls=545
Step-by-step explanation:
total no. of students=940
let no. of girls=x+150
let no. of boys=x
x+(x+150)=940
x+x+150=940
2x+150=940
2x=940-150
2x=790
x=790/2
x=395
no. of boys=395
no.of girls=395+150=545
this is my answer.
If the 27th term of an arithmetic sequence is -124 and the common difference is -11 then what was the first term?
Answer:
First term = 162.
Step-by-step explanation:
a27 = a1 - 11 (27 - 1)
= a1 - 286
So a1 - 286 = -124
a1 = 162.

Find the solution of the system of equations.
2x+3y= -4
x + 9y = 13
Answer:
(-5,2)
Step-by-step explanation:
Using elimination:
Multiply x+9y=13 by -2 which would equal -2x-18y=-26
Then you add the two question together
2x+3y=-4 + -2x-18y=-26
Since 2x-2x=0, you can cross them out
3y+(-18y)= -15y
-4+-26 =-30
You are now left with -15y=-30
Then you divide both by -15
Your answer is y=2, now you need to find x by plugging y into one of the equations
x+9(2)=13
x+18=13
Subtract 18 from both sides
x=-5

GEOMETRY!!! Will give brainliest
Can someone please help me with this
Answer:
B
Step-by-step explanation:
So, lets think about how many inches are in a foot. If you dont know, think about how many inches are on a ruler, 12 right? Well, thats how many inches are in a foot.
So knowing that the truck is 162 inches, lets find how many inches the bridge is. We can do this by multiplying the feet, which is 12. 12(feet) times 12(inches in a foot) equals 144.
Remember that the problem said 12 feet and 5 inches, so we know 12 feet is 144 inches, now we jsut need to add the 5 inches. Well, 144 plus 5 is 149. Clearly, 162(truck) is greater than 149(bridge).
How much taller? lets subtract the heigh of the truck by the bridge: 162-149.
This should get you 13.
So the answer must be that the truck is 13 inches taller.
A telephone call costs $0.15 for the first minute, plus $0.05 for each
additional minute. The total cost of the call was $1.30. This equation
can be used to find m, the length in minutes of the telephone call.
0.15 + 0.05(m - 1) = 1.30
How do I graph y=3sin(x+pi/3)-2 and what are the amplitude, asymptotes/ phase shift and critical points and period
Step-by-step explanation:
amplitude is 3. so the sin will start at zero and go up to 3 and down to -3. asymptote are at 3 and -3
it's period didn't change it's 2π
it's phase shifted horizontally π/3 to the left
it's phase shifted vertically 2 units down
