Answer: 4.87 x 10^9 is greater than 9.212 *10^8
Step-by-step explanation:
4.87 x 10^9 is greater than 9.212 *10^8 because it has the greater exponent.
4.87 * 10^9 = 4,870,000,000
9.212 *10^8= 921,200,000
4,870,000,000 > 921,200,000

Tom has to take three medicines each day. One is to be taken
every 3 hours, one every 4 hours and one just four times a day.
He takes his first dose on Monday at 9am, what is the next time he
takes all three medicines together?
Please help
Answer:
9pm Monday
Step-by-step explanation:
It would take 12 hours, that would be when all of the medicines would be taken at the same time, because 3/4/6 are factors of 12

7/3
Step-by-step explanation:
To get the answer, we add all of the numerator numbers together since the denominators are all the same. 3 + 4 + 7 = 7 + 7 = 14
The answer is 14/6. We can then simplify it and divide both the numerator and the denominator by 2. That gives us 7/3 and that is our final answer.

What is the image point of (3,8) after a translation right 4 units and up 1 unit?
Answer:
its going to be (7,9)
Step-by-step explanation:
Answer:
The image of the point after the translation would land the point at (7, 9).
Step-by-step explanation:
When you're moving a point right, imagine adding the number of units you are going right to the x value. When you're moving a point up, imagine adding the number of units you are going up to the y value.
(3 + 4, 8 + 1)
(7, 9)
So, the image of the point of (3, 8) after a translation right 4 units and up 1 unit is going to be (7, 9).

Explain how to find the median.
Answer:
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
Step-by-step explanation:
have a great day
There are two ways to find the median, depending on what situation it is.
The first, is to simply arrange the number set into proper numerical format (least to greatest), then count from both sides towards the middle to find the median or middle number.
The latter, is when we have a number set that has an equal amount of numbers. For this, we would again, arrange it into proper numerical format, and the count from both sides up. However, there will be two numbers at the middle. So, what we do, is that we have to add them up and then divide by 2 since there are only those two numbers at the middle. Once, the numbers are added up and divided by 2, you will get the resulting median.
Example: Find the median of the data set below.
1,2,3,4,5,6,7,8,9,9
There are 10 numbers in this data set.
It's already been arranged into proper numerical format.
So, all we have to do is, find the two middle numbers and then add them up and divide.
The two numbers at the middle are: 5 and 6.
Add them up.
5 + 6 = 11
Divide by 2.
11/2 = 5.5
Thus, the median of the data set is 5.5

The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
Answer:
x = 53
Step-by-step explanation:
Using the information that angles in a triangle add up to 180°, we can set up and equation to find the value of x
⇒ Use the information that angles in a triangle add up to 180°, form an equation
→ x - 11 + 48 + 90 = 180
⇒ Simplify
→ x + 127 = 180
⇒ Minus 127 from both sides to isolate x
→ x = 53
We can substitute the value of x back into x - 11 + 48 + 90 = 180 to see if our value of x is correct, if we end up on 180 on both sides then the value of x is correct
→ x - 11 + 48 + 90 = 180
⇒ Substitute in the value of x
→ 53 - 11 + 48 + 90 = 180
⇒ Simplify
→ 180 = 180
This means that x = 53 is correct

In a certain isosceles triangle, the base is 1 1/2 times as long as each leg and the perimeter is 63. How long is the base?
Answer:
The base is 27 units long.
Step-by-step explanation:
This is a solve the system question. Call the length of the base B and the length of each leg L. We are told:
[tex]B=1.5L[/tex]
and
[tex]B+2L=63[/tex]
Sub the first equation into the second:
[tex]1.5L+2L=63\\3.5L=63\\L=18[/tex]
Now that we have the leg length, sub that into either of the original equations to find the base. I'll use the first equation:
[tex]B=1.5(18)\\B=27[/tex]

Pedro withdrew some money from his bank account. After giving $15 to his cousin, he spent 1/5 of what was left on a lamp, then he used the remaining $128 to buy a calculator. What percent of Pedro’s money did he give to his cousin?
*Please Show Work*
Answer:
He gave 8.57 % of his money for his cousin.
Step-by-step explanation:
In order to calculate the percent that Pedro gave to his cousin, we first need to calculate his total amount, which is given by "x". This is given by:
x = 15 + (x - 15)/5 + 128
x = 15 + x/5 - 3 + 128
x = x/5 + 140
x - x/5 = 140
(5*x - x)/5 = 140
4*x = 700
x = 175
He had originally $175 and gave $15 to his cousing, therefore we can use a rule of three to calculate the percent that he gave to his cousin:
$175 -> 100%
$15 -> y%
175*y = 1500
y = 1500 / 175
y = 8.57 %

Logan is doing a handstand dive from a 12 meter platform. The equation that models the path of her dive is given by LaTeX: h=-4.9t^2+12h = − 4.9 t 2 + 12, where t is seconds. After how many seconds will Logan hit the water?
Answer:
Time, t = 2.44 seconds
Step-by-step explanation:
Logan is doing a handstand dive from a 12 meter platform. The equation that models the path of her dive is given by :
[tex]h=-4.9t^2+12t[/tex]
It is required to find the time after which Logan will hit the ground. At this point, h = 0
[tex]-4.9t^2+12t=0\\\\t(-4.9t+12)=0\\\\t=\dfrac{12}{4.9}\\\\t=2.44\ s[/tex]
So, after 2.44 seconds it will hit the water.

Given the definitions of f(x) and g(x) below, find the value of g(f(-1)).
f(x) = -4x – 7
g(x) = x² + 7x – 2
Answer:
(x)=(x-7)(x-4)
g(x)=x(2)+7x - 2
Now find a common denominator. (x+10)(x-4) is a good one.
x-16/(x+10)(x-4)+x-4/(x+10)(x-4)
2x-20/(x+10)(x-4)
The value of function g(f(-1)) is -70.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
The value of functions,
f (x) = -4x - 7
g (x) = x² + 7x - 2
Now, Value of function g(f(-1)) as;
g(f(x)) = g(-4x - 7)
= (-4x - 7)² + 7(-4x - 7) - 2
= (4x + 7)² + 7 × -4 × x - 7 × 7 - 2
= 16x² + 49 + 56x + 28x - 49 - 2
= 16x² + 84x - 2
Thus, g(f(x)) = 16x² + 84x - 2
Now, To find value of g(f(-1)) we can substitute x = -1,
g(f(-1)) = 16(-1)² + 84(-1) - 2
= 16 - 84 -2
= -70
Thus, The value of function g(f(-1)) is -70.

Angie has a square dog pen with a perimeter of 20 meters. She wants to put a diagonal piece of fencing inside her pen to cut it in half because her 2 dogs have been fighting. How long of a piece of fencing will she need to buy? Hint: The formula for finding the hypotenuse of a right triangle is: a² + b² = c²
Answer: 7.07 miles
Step-by-step explanation:
Hi, to answer this, first, we have to find the length of the square dog pen.
Perimeter of a square = 4 x sides
Replacing with the value given:
20 = 4 s
Solving for s:
20/4=s
Side = 5 meters
Since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case length of the diagonal) and a and b are the other sides.
Replacing with the values given:
c^2 = 5^2 + 5^2
c^2 = 25+25
c^2 = 50
c = √50
c = 7.07 miles

Your bill at a restaurant is $35.00. There is an 8% meals tax (sales tax). How much is the tax? You want to leave a 20% tip. You should calculate the tip on the $35.00 (not the cost after the tax). How much is the tip? What is the total bill?
Answer:
$44.8
Step-by-step explanation:
The tip:
35*0.2=$7
The total bill:
35*8% = 35*0.08 = 2.8
35 + 2.8 +7 = 44.8
(I added 35 for the price of the actual lunch, and the 7 for the tip)
Alternatively, you can just add the 8% and the 20% and the 100% (for the lunch itself), and then multiply the $35.
8%+20%+100%=0.08+0.2+1= 1.28
1.28*35=$44.8
