Answer:
6*10^-3 > 5*10^-3
Step-by-step explanation:
[tex]6*10^{-3}\\6*\frac{1}{10^{3} }\\6*\frac{1}{1000}\\\frac{6}{1000}=\frac{3}{500}=0.006[/tex]
[tex]5*10^{-3}\\5*\frac{1}{10^{3} }\\5*\frac{1}{1000}\\\frac{5}{1000}=\frac{1}{200}=0.005[/tex]
0.006>0.005, therefore, 6*10^-3>5*10^-3

1/4(2x + 8) = –16
A)
-18
B)
-24
D
-28
D)
-36
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{1}{4}[/tex] (2x + 8) = - 16
Multiply both sides by 4 to clear the fraction
2x + 8 = - 64 ( subtract 8 from both sides )
2x = - 72 ( divide both sides by 2 )
x = - 36
Answer:
The answer is option DStep-by-step explanation:
[tex] \frac{1}{4} (2x + 8) = - 16[/tex]First multiply through by 4
That's
[tex]4 \times \frac{1}{4}(2x + 8) = - 16 \times 4 \\ 2x + 8 = - 64[/tex]Subtract 8 from both sides
We have
[tex]2x + 8 - 8 = - 64 - 8 \\ 2x = - 72[/tex]Divide both sides by 2
That's
[tex] \frac{2x}{2} = - \frac{72}{2} [/tex]We have the final answer as
x = - 36Hope this helps you
How can 3.14159 be based on a multiple on the divisor?
Answer:
Here the value is similar to the value of pi ([tex]\pi[/tex])
Step-by-step explanation:
22 / 7 = [tex]\pi[/tex]
22 / 7 = 3.14159
So it is based on a multiple on the divisor 7
The cross-sectional areas of a right pyramid and a right cylinder are congruent. The pyramid has a height of five units, and a right triangle has a height of three units. Which conclusion could be made from the given information
Answer:
the volume of the right cylinder is 1.8 times the volume of the pyramid
Step-by-step explanation:
The volume of a pyramid is
[tex]V = \dfrac{1}{3} \times B\times H[/tex]
where the height of the pyramid is 5
[tex]V = \dfrac{1}{3} \times B\times 5[/tex]
[tex]V = \dfrac{5}{3} B \ units ^3[/tex]
On the other hand, the volume of a right cylinder is
V = BH
where the height of the right cylinder = 3 units
V = 3 B units³
Since we know that the cross-sectional areas are congruent, comparing the two-volume, we have the ratio of their volumes to be:
[tex]\dfrac{V_p}{V_c}= \dfrac{\dfrac{5}{3}B}{3B}[/tex]
[tex]\dfrac{V_p}{V_c}= \dfrac{5}{9}[/tex]
[tex]9 V_p = 5 V_c[/tex]
[tex]V_c = 1.8 \ V_p[/tex]
Hence, the volume of the right cylinder is 1.8 times the volume of the pyramid
All good football players are over 200 pounds. Earl is 230 pounds. Kaylie concludes Earl is a good football player. Is her conclusion valid? Explain.
Answer:
I don't think so
Step-by-step explanation:
If being over 200 lbs makes you a good football player, then Earl could be a good player. But you need to be skilled at football to be good at it. Your weight doesn't make you good at something. So in my opinion, I don't think Kaylie's conclusion is valid.

Write 6 x 10 x 10 x 10 x 10 with an exponent.
Answer:
the answers is 6x 10 4
Step-by-step explanation:
The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
We have been given an expression as
6 x 10 x 10 x 10 x 10
Here we can see the base 10 multiplied by itself 4 times.
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]
The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

Owen knows he only has three pencils in his backpack, and they are all yellow. He reaches into his backpack without looking and takes out a pencil. What is the probability that the pencil was yellow? Answer options with 5 options A. 0-thirds B. 1-third C. 2-thirds D. 3-thirds E. 3 over 1 I NEED ACTUAL ANSWERS NOT JUST STUPID PEOPLE WITH A POOR SENSE OF HUMOR
Answer:
D; 3-thirds
Step-by-step explanation:
Here is a probability question.
Firstly, we need to understand that the probability of any event is between 0 and 1; it cannot be negative and cannot be more than 1.
So the probability we want to calculate here is simply the probability of drawing a yellow pencil.
The way to go about this is by dividing the number of yellow pencils by the total number of pencils
Mathematically;
Probability of bringing out a yellow pencil= Number of yellow Pencils/ Total number of pencils
From the question, we are told that the number of pencils = number of yellow pencils = 3
Thus the probability will be 3/3 = 1
This cannot be found in the options right?

Grissom draws different sized spheres in a notebook. He knows there is a relationship between the volume of the sphere and the length of its diameter. What is the independent quantity in the situation?
Answer:
The independent quantity in the situation is the length of the diameter.
Step-by-step explanation:
Consider a relationship between two variables.
Of the two variables one variable is dependent upon the other.
Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variable values are changed.
Independent variables are the variables that are being altered to see a proportionate change in the dependent variable.
In this case, it is provided that Grissom knows there is a relationship between the volume of the sphere and the length of its diameter.
With every sphere that Grissom draws, the volume of the sphere changes according to its diameter length.
That is the volume of the sphere depends upon the length of its diameter.
Thus, the independent quantity in the situation is the length of the diameter.

The path of water from a hose on a fire tugboat can be approximated by the equation y=-0.0055x^2 +1.15x + 5, where y is the height above the ocean and x is the distance from the tugboat. When the water is 6 ft above the ocean how far is it from the tugboat
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is [tex]y=-0.0055x^2 +1.15x + 5[/tex]
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
[tex]6=-0.0055x^2 +1.15x + 5[/tex]
we can arrange this properly to form a quadratic equation by grouping like terms.
[tex]-0.0055x^2 +1.15x -1=0[/tex]
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft

Ava has 34 candy bars. If
a box contains 5 bars and she has 4 extra candy bars
determine how many boxes
She has?
[tex]\bf Step-by-step~explanation:[/tex]
If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.
[tex]\bf Step~1:[/tex]
Divide the number of candy bars (34), by the number each box can hold (5)
[tex]\bf\frac{34}{5}=6.8[/tex]
Since we cannot have 6.8 boxes, we have to round down to 6.
[tex]\boxed{\bf Our~final~answer:~6~boxes}[/tex]
[tex]\bf Check~our~answer:[/tex]
To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!
A van can travel 18 miles on each gallon of gasoline. At that rate, how many miles can the van travel on 15 gallons of gasoline? 33 miles 83 miles 120 miles 270 miles Mark this and return
Answer:
270 miles
Step-by-step explanation:
if 1 gallon = 18 miles
then 15 gallons = x miles
cross multiply
1 × x = 15×18miles
x = 270 miles
so it travels 270 miles on 15 gallons of gasoline
