Which expression is represented by the diagram? ( Marked 1-4, I can't paste the question.)
Answers
Answer:
-6-(-1)
Step-by-step explanation:
Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6. Then since the last box is being taken away, we are subtracting it. The last box is still negative though so the last part is -1. Since -6 subtracted by -1 is -6-(-1), the answer is:
-6-(-1)

Answer:
[tex]7+(11-4\times 2)=10[/tex]
Step-by-step explanation:
So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.
So, we have:
[tex]7\text{ } 11\text{ } 4\text{ } 2\text{ } =\text{ } 10[/tex]
So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:
[tex]7+(11-4\times 2)=10[/tex]
This is a true number sentence. Let's do it to make sure.
First, do the operations inside the parentheses.
Multiplication comes first, so multiply:
[tex]7+(11-8)=10[/tex]
Again, do the parentheses first. Subtract:
[tex]7+(3)=10[/tex]
Now add:
[tex]10=10[/tex]
So our answer is correct :)
q1: How can you rewrite -8 -− 10 as an additional problem? q2: Find the difference: -11 -− 5
Answers
Answer:
1. 2
2. -6
Step-by-step explanation:
I guess you tried to write -8-(-10) in the first question. Minus sign cancels out minus sign to give addition sign. So that is -8+10 which is 2.
The second question the sam thing applies -11-(-5) which is -11+5 which is -6

The density of a certain material is such that it weighs 6 pounds per pint of volume. Express this density in grams per liter. Round your answer to the nearest whole number.
Answers
Answer:
Density = 4779 grams per liter
Step-by-step explanation:
here we need to convert
pounds to gram
pint to liter
1 pound = 454 grams
1 pint = 0.57 liters
given
density = 6 pounds per pint
now using grams in place of pound and
liter in place of pint we have
density = 6 pounds per pint = 6*454 grams /0.57 liters
density = 2724 pounds/ 0.57 liters = 4778.94 grams / liters
Density when rounded to nearest whole number is 4779 grams / liters

Robot 1 is at Asteroid U. Calculate the distance between U (38,22) and W (55,30) to the nearest thousandths, then add a driveDistance block to drive the robot to Asteroid W.
Answers
Answer:
When we have two vectors:
A = (a1, a2)
B = (b1, b2)
The distance between these two vectors is:
D = √( (a1 - b1)^2 + (a2 - b2)^2)
In this case, the vectors are:
U = (38, 22) and W = (55, 30)
The distance between U and W is:
D = √( (38 - 55)^2 + (22 - 30)^2 )
D = √( 289 + 64) = √353 = 18.7882
We want to round it to the nearest thousandths (the third digit to the right of the decimal point).
Then we must look at the next one (the fourth)
if the fourth digit is 5 or smaller, we round down
if the fourth digit is larger than 5, we round up.
We can see that in 18.7882 the fourth digit after the decimal point is a 2, so we round down, then the distance between U and W is:
D = 18.788
Now i guess that you want a line that connects U with W so the robot can follow it,
To find the line you can use a linear relation:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
So we want a line that passes through the points U and W, the slope of this line will be:
a = (30 - 22)/(55 - 38) = 0.47
Then the equation is:
y = 0.47*x + b
to find the value of b, we know that this line passes through the point (38,22) then:
y = 22 = 0.47*38 + b
b = 22 - 0.37*38 = 7.94
The line that can use the robot to go from U to W is:
y = 0.47*x + 7.94

[tex]n = \frac{4}{5} (m + 7)[/tex]First of all multiply both sides by 5
That's
[tex]5n = 5 \times \frac{4}{5} (m + 7) \\ 5n = 4(m + 7)[/tex]Next divide both sides by 4
That's
[tex]m + 7 = \frac{5n}{4} [/tex]
Subtract 7 from both sides to make m stand alone

SALES A daily newspaper had 12,125 subscribers when it began publication. Five years later it had 10,100 subscribers. What is the average yearly rate of change in the number of subscribers for the five-year period?
Answers
Answer:
The average change is 405
Step-by-step explanation:
The initially the number of subscriber = 12125
After five years the number of subscriber = 10100
Now we have to find the average change in the number of subscribers.
The average yearly change = change in subscriber/number of years.
Now insert the values in the above formula.
The average yearly change = (12125 – 10100) / 5
The average yearly change = 2025/5
The average yearly change = 405
Answer: The average change is -405

Step-by-step explanation:
The square root of the number in the fractional form [tex]\frac{169}{196}[/tex] is the number in fractional form [tex]\frac{13}{14}[/tex].
Given a number:
[tex]\frac{169}{196}[/tex]
It is required to find the square root of the number.
The square root of the fraction can be found by taking the square root of each component and dividing it.

area of a circle is [tex]\pi[/tex]r²
so B is 12[tex]\pi[/tex]in²
The area of the base of the cylinder in the image given will be 12pi in.
How to Find the Base Area of a Cylinder?The formula for the volume of a cylinder = πr²h, where:
Base area of the cylinder (B) = πr²
(r is the radius)
The Height of the cylinder = h
The given cylinder has the following,
Height of cylinder (h) = 7 in.
Volume of cylinder = 84pi in.³
Then Substitute into the volume formula:
(πr²)7 = 84pi
(B)7 = 84pi (B = area of the base)
Divide both sides by 7;
(πr²)7/7 = 84pi /7
B = 12pi
Therefore, the area of the base of the cylinder in the image given will be 12pi in.
