3.456x(2.05x10^5) = ?
Answer:
708480
Step-by-step explanation:
You follow the order of BEDMAS. There are brackets in this equation, meaning we have to focus on what is inside the brackets first. The next step is Exponents. So you multiply 2.05 by 10^5.
This would give you 205000.
You then multiply this number by the number on the outside of the brackets which is 3.456.
This would give you 708480. (You can get these answers by using a calculator).
Don't forgot to follow the order of BEDMAS or whatever law of operations you were taught (BIDMAS/BIMDAS etc)

The temperature rose from -4 F to 45 F in spearfish, South Dakota and only two minutes. By how many degrees does the temperature change?
Answer: 49 degrees
Step-by-step explanation:
pls show work and explain how to do it
Step-by-step explanation:
1. We can see that the two vertical lines are parallel. Since one angle is 80º, then the other side should be 100º, since the straight line is 180º.
2. If the angle on the right is 80º, then that means the angle with y and 40º add up to 100º.
3. 100º - 40º = 60º.
Our final answer: y = 60º

Jackson drops a pumpkin off a balcony from
a height of 64 feet. Analyze the time in seconds it takes
for the pumpkin to smash on the ground.
Answer:
t = 1.15 seconds.
Step-by-step explanation:
The pumpkin is dropped from the height of = 64 feet.
Now we have to find the time taken to reach the pumpkin on ground. Use the below formula to find the time taken.
H = ½ gt^2
H = height
g = 9.8 (always contant )
t = time taken.
Now insert all the values in the formula.
H = ½ gt^2
64 = ½ ×9.8× t^2
(64×2) / 9.8 = t^2
t = 1.15 seconds.

Shanelle invested $10,000, and at the end of one year, she received $805 in interest. She invested part of the money in an account earning 10% simple interest and the remaining money in an account earning 7%simple interest. How much did she invest in each account?
Step-by-step explanation:
Let the first part be x. Then,
the second part will be (10000-x).
So, According to question,
(10% of x) + { 7% of (10000-x)} = 805
(10/100*x) +{7/100*(10000-x)} = 805
(x/10) + (70000-7x/100) = 805
Then,
We will take the lcm of 10 and 100 which is 100 and then add both the fractions.
Solution:
10x + 70000-7x/ 100 = 805
3x + 70000/100 = 805
3x + 70000 = 805*100
3x + 70000 = 80500
3x = 80500-70000
3x = 10500
x = 10500/3
x = 3500
So the first part is 3500.Then,
the second part will be (10000-3500)
= 6500

2t+ 1 = 3t-1 + 3
3 4
Answer:
t = -1
Step-by-step explanation:
[tex]2t + 1 = 3t - 1 + 3[/tex]
Collect like terms and simplify
[tex]2t - 3t = - 1 + 3 - 1 \\ - t = 1[/tex]
Divide through by -1
[tex] \frac{ - t}{ - 1} = \frac{ 1}{ - 1} \\ t = - 1[/tex]
Answer:
t = - 2
Step-by-step explanation:
[tex]\frac{2t + 1}{3} = \frac{(3t-1) + 3}{4}[/tex]
First we need to cross multiply to get rid of the division to make it easier to solve.
Multiply 2t+1 by 4 and (3t-1) + 3 by 3
4 ( 2t + 1 ) = 3 ( ( 3t - 1 ) + 3 ) On the right we need to combine terms.
4 ( 2t + 1 ) = 3 ( 3t - 1 + 3 )
4 ( 2t + 1 ) = 3 ( 3t + 2 ) Multiply
4 * 2t + 4 * 1 = 3 * 3t + 3 * 2 Remember order of operations. Multiplication comes before addition and subtraction.
4 * 2t + 4 * 1 = 3 * 3t + 3 * 2
8t + 4 = 9t + 6 Subtract 8t from each side
8t - 8t + 4 = 9t - 8t + 6
4 = t + 6 Subtract 6 from each side
4 - 6 = t + 6 - 6
4 - 6 = t
- 2 = t

What is the justification for the step taken from line 2 to line 3?
Answer:
They subtracted 2x from both sides.
Step-by-step explanation:
They removed 2x from each side because in order to find x it will have to be removed on one side. Since 2x - 2x = 0 it is 2x is out of the equation for the right side and on the left side -2x -(-4x) = -6x which means that there is one x variable left in the equation thus making it solvable.
A water well drilling rig has dug to a height of -60 ft after one full day of continuous use.
a. Assuming the rig drilled at a constant rate, what was the height of the drill after 15 hours?
b. If the rig has been running constantly and is currently at a height of -143.6 ft, for how long has the rig been running? explain
There are 24 hours in a day and so 15 hours is 15÷24=58 of a day. Since the rig drills 60 feet underground in a day, in 58 of a day it will drill
(58 days)×(60feetday)=3008 feet.
So the rig will have drilled 3008=37.5 feet underground in 15 hours.
The rig drills 60 feet underground per day so to find how long it has been running to go 143.6 feet underground, we need to calculate
(143.6 feet)÷(60feetday)=143.660 days.
This is about 2.4 days. Alternatively, it is 57.44 hours
We know that the rig drills at a constant rate, so there is a proportional relationship between the two quantities d, the height to which the drill has dug, and t, the number of days the drill runs. It drills at -60 feet per day, so we can represent this relationship with the equation:
–60t=d
Since 15 hours is 1524=58 days, we can use the equation to find d:
–60⋅58=d
Since the depth is the same whether we think of it as a positive depth below the surface or a negative height above the surface, we can find this value by multiplying 60⋅58=37.5 and then noting that the sign must be negative if we are representing positions below the surface of the earth by negative numbers. So d=–37.5 and the drill will be at height -37.5 feet after 15 hours.
Likewise, if we know the drill has dug to -143.6 feet, we can use the equation again, this time to find t:
−60t=−143.6
so t=(−143.6)÷(−60). Since the amount of time would be the same if we were working with positive feet below the surface of the earth and a drill rate of 60 feet per day below the earth surface, we can find this value by dividing 143.6÷60, which is about 2.4 days.
