Which expression is represented by the diagram?
HE
Answer:
The expression -10 - (-4) represents the given diagram.
Step-by-step explanation:
Here, the total number of blue boxes marked with (-) = 10
So, in Total number of (-) are 10 x (-1) = -10
Now, the number of boxes crossed out = 4
So, the total value crossed out = 4 x ( Value on each box) = 4 ( -1) = -4
⇒ The value Left after crossing = Total value - The crossed out value
= -10 - (-4)
Hence, the expression -10 - (-4) represents the given diagram.

Find the midpoint of the segment with the following endpoints. (5,3) and (1,9)
Answer:
(3, 6)
Step-by-step explanation:
If you create a mini graph, like I did, you would have seen that the middle point is at the co-ordinates (3,6). I have attached a image to this reply, with my "graph". (Sorry if its a little ugly, but that doesn't matter, the math does.)
The scale of a map is 1 cm to 5 km. A farm is represented by a rectangle measuring 1.5 cm by 4 cm. What Is the actual area of the farm?
*55 points if you answer
Answer:
150 km squared
Step-by-step explanation:
5*1.5=7.5
4*5=20
7.5*20=150
Answer:
150km²
Step-by-step explanation:
1.5 x 5 = 7.5
4 x 5 = 20
20 x 7.5 = 150

solve completing the square of x^2-10x+25=2
Answer:
the answer is 4
Step-by-step explanation:
Answer:
x=5±√2
Step-by-step explanation:
x^2-10x=-23
x^2-10x+25=-23+25
(x-5)^2=2
x-5=±√2
x=5±√2
What is the slope and what is the y-intercept
Answer:
(1,2) and slope = 0
Step-by-step explanation:
Look where the line crosses the y and because the line is parallel to the x the slope is equal to zero
can i graph a line if i know the slope and the y intercept? please answer.
Answer:
Step-by-step explanation:
yes you can
the form of the equation is y=mx+b
the y intercept (0,b) when x=0 the y=b
and if you know the slope m, then you can form the equation
example : m=3 , and y intercept is (0,1)
y=mx+b
y=3x+b ( at point (0,1)
1=3(0)+b
b=1
the equation is y=3x+1
Find the value of X in the triangle shown below.
Mai is filling her fish tank How many gallons of water will be in the fish tank after
3 minutes?
Answer:
4.8 gallons of water.
Step-by-step explanation:
Mai is filling his fishing tank with water. This shows a proportional relation between the time and the amount of water filled.
Amount of water filled (In gallons) ∝ Duration (In minutes)
w ∝ t
w = kt ---------(1)
For t = 0.5 gallons,
Amount of water = 0.8 gallons
From equation (1),
0.8 = k(0.5)
k = 1.6
So the proportionality equation will be,
w = 1.6t
Now we have to find the amount of water filled in 3 minutes.
w = 1.6 × 3
= 4.8 gallons
Therefore, water filled in the tank after 3 minutes = 4.8 gallons.

Answer:
ºC = (ºF - 32) / (9/5)
Step-by-step explanation:
Take the formula that you already have:
ºF = (ºC × 9/5) + 32
Flip the ºF and ºC:
ºC = (ºF × 9/5) + 32
Move the whole number to the right side of the equation and change it's sign:
ºC = (ºF - 32) / (9/5)
(This will also force the fraction to move to the right hand side of the equation, but for that you keep the value of the number the same)
Hope this helped!
-2x < 6 and 4x - 7 > 21
Answer:
x > -3, x >7
Step-by-step explanation:
for -2x < 6:
first divide each side by 2: -x < 3
then divide each side by -1, so the final answer is: x > -3
(whenever you divide by a negative number you have to flip the sign)
for 4x-7>21:
first, add 7 to each side: 4x>28
then divide each side by 4, and the final answer is: x >7
Kenya plans to make a down payment plus monthly payments in order to buy a motorcycle.
At one dealer she would pay $2,450 down and $200 each month. At another dealer, she
would pay $2,950 down and $175 each month. After how many months would the total
amount paid be the same for both dealers? What would that amount be?
Answer:
it would take 20 months and it would cost $6450
Step-by-step explanation:
in order to solve this question we need to equate the amount at each dealer against one another
Find the number of monthsmake the months as an unknown variable (x)
2450 + 200x = 2950 + 175x
now make x the subject of formula
200x - 175x = 2950 - 2450
25x = 500
x = 500/25
x = 20
the amount would be the same in 20 months
to find the amount it would be after those monthsreplace x with 20
2450 + 200 (20) = 6450
$6450

a train can travel at a rate of 85 miles per hour at this rate how many hours would it take the train to go 102 miles
Given:
Speed of train = 85 miles per hour
Total distance = 102 miles
To find:
The time taken by train to cover 102 miles.
Solution:
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
On substituting the values, we get
[tex]85=\dfrac{102}{Time}[/tex]
[tex]Time=\dfrac{102}{85}[/tex]
[tex]Time=1.2[/tex]
Therefore, the time taken by train to cover 102 miles is 1.2 hours.

Step-by-step explanation:
The relantionship is perpendicular, because when you do the procedure that the question talks about, you find a circumference, and A and B are points of that cirumference.
As the segment is her diameter, we know that they, the points A and B, are perpendicular to the segment.
Why?
Because the definition of a circumference is:
> A single point in a bidimensional space that has the same distance from a infinity amount of points - remember that a point has no dimension, so there is infinity points over one point -, what became to be a circumference.
Also, take note that the lower distance for any point is a straight segment, who is perpendicular for both points.
But talk maybe do not help. Look the annex.
