Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8?
Answer:
2.3 × is 20,000 times greater than 1.15 ×
Step-by-step explanation:
Given as :
The first number= x = 2.3 ×
The second number= y = 1.15 ×
Let The first number is z times greater than second number
i.e x = z × y
Or, z =
Or, z =
Or, z = 2 ×
∴ z = 20,000
So,The first number is 20,000 times greater than second number
Hence, 2.3 × is 20,000 times greater than 1.15 ×

Which number is larger, 2 x 10^-3 or 3 x 10^-2? Explain.
Answer:
Step-by-step explanation:
[tex]2 \times 10^{-3}=\frac{2}{10^3}=\frac{2}{1000}=0.002\\3 \times 10^{-2}=\frac{3}{10^2}=\frac{3}{100}=0.03=0.030\\0.030>0.002\\so~3 \times 10^{-2} ~is~larger~than~the~other.[/tex]

m-8=33 can you plz help me do this
Answer:
41
Step-by-step explanation:
m-8=33
Combine like terms by moving 8 to the other side
m=33+8
m=41
I hope this helps! Please comment if you have any questions.
Answer:
M = 41
Step-by-step explanation:
This question is a basic one. Don't let the letter freak you out haha. All you need to do for something like this is find out what minus 8 is 33. An easy way we can do this is just add 8 to 33. 33 + 8 = 41.
41 - 8 = 33.
Your answer is 41.
Hope this helps and have a nice day!
A container ship is overtaking an oil tanker on the way out of Harwich Harbor, and the first mate notices that if he starts walking from the front of the container ship when the two ships start overlapping, he reaches the back as the two ship separate. He walks at 3 km/hour.
If the container ship is 100 m long, and travelling at 12 km/hour, how long is the oil tanker?

Step-by-step explanation:
For which values of a the system has at least one solution: x≤7 x≥a urgent pls help now
Answer:
We have the system:
x ≤ 7
x ≥ a
Now we want to find the possible values of a such that the system has, at least, one solution.
First, we should look at the value of a where the system has only one solution:
We can write the 2 sets as:
a ≤ x
x ≥ 7
So, writing both together:
a ≤ x ≤ 7
if a is larger than 7, we do not have solutions.
then a = 7 gives:
7 ≤ x ≤ 7
Here the only solution is 7.
Now, if a is smaller than 7, for example 5, we have:
5 ≤ x ≤ 7
Now x can take different values, so we have a lot of solutions.
Then the restrictions for a, such that the system has at least one solution, is:
a ≤ 7.
Geri spent Friday, Saturday, and Sunday selling a total of 24 magazine orders for her school fundraiser. The amounts she sold, respectively, on the three days were consecutive even integers. How many did she sell on each day?
Answer:
8
Step-by-step explanation:
So since there is 3 days and the total is 24 you divide and that will give you 8! Integers are a whole number btw (:
Translate the following into a verbal expression:
X2 - 5
Write an algebraic expression for the two verbal expressions: 1. The product of 5 and twice a number x, decreased by the product of 3 and that same number. 2. Twice the sum of a number x, and another number y, increased by the product of the first number squared and 8.
Answer:
7x for the first expression
2x + 2y + 8x^2
Step-by-step explanation:
5(2x) - 3x
= 10x - 3x = 7x
2x + 2y + x^2(8)
= 2x + 2y + 8x^2
What is the range of the function f(x) = 4x + 3 when the domain is {−3 , 2 , 4}
Hey there! I'm happy to help!
The range of a function is all of the outputs. Let's plug in our inputs and find these outputs.
4(-3)+3
-12+3
-9
4(2)+3
8+3
11
4(4)+3
12+3

Find the midpoint of the line segment with the given endpoints. (-3.1, -2.8) and (-4.92, -3.3)
Answer:
Step-by-step explanation:
(-3.1 - 4.92)/2 = -8.02/2 = -4.01
(-2.8 - 3.3)/2 = -6.1/2= -3.05
(-4.01. -3.05) the midpoint
Divide.
-6 7/8 divide by (-3 3/4)

Which set of angle measures could be the interior angles of a triangle? A. 15°, 48°, 27° B. 56°, 45°, 46° C. 42°, 84°, 64° D. 93°, 29°, 58°
Answer:
D. 93°, 29°, 58°
Step-by-step explanation:
In a triangle we can only have 3 Interior angles.
The sum of the Interior angles in a triangle = 180°
Adding up the given Interior angles in the above question:
A. 15°, 48°, 27°
= 15° + 48° + 27°
= 90°
90° ≠ 180°
Option A is wrong
B. 56°, 45°, 46°
= 56 ° + 45° + 46°
= 147°
147° ≠ 180°
Option B is wrong
C. 42°, 84°, 64°
= 42° + 84° + 64°
= 190°
= 190° ≠ 180°
Option C is wrong.
D. 93°, 29°, 58°
93° + 29° + 58°
= 180°
180° = 180°
Option D is the correct Option.
Therefore, the set of angle measures that could be the interior angles of a triangle is Option D. 93°, 29°, 58°

A large ice chest holds 62 liters of water. A smaller chest holds 4/5 as much water
How many liters of water does the smaller chest hoid? Move a number to each box to show the answer. HELP ASAP.
Answer:
Step-by-step explanation:
Since a large ice chest holds the water = 62 liters
And smaller chest holds the water = [tex]\frac{4}{5}[/tex] of the larger ice chest
= [tex]\frac{4}{5}\times 62[/tex]
= [tex]\frac{248}{5}[/tex] liters
Therefore, fraction that represents the amount of ice water in the smaller ice chest will have 0 in the first box, 248 in the numerator and 5 in the denominator.
[tex]0\frac{248}{5}[/tex]
