Area of triangle with points (7,7) (10,3) (7,3)
Answer:
The area of the triangle is of 6 units squared.
Step-by-step explanation:
Representation of the triangle:
This triangle, in the cartesian plane, has the vertices at these following points.
(7,7)
| -> 4 units down
(7,3) --- (10,3) -> 3 units to the right.
This can be represented as a right triangle with sides 4 and 3.
Area of a right triangle:
The area of a right triangle is the multiplication of the lengths of its sides divided by 2. So
4*3/2 = 12/2 = 6.
The area of the triangle is of 6 units squared.
Find the area of the shaded region, round to the
nearest hundredth where necessary.

please help 75 points
Answer:
The median for the first plot is 3
The median for the second plot is 7
The largest value for the first plot is 6
So the difference for the first plot is 6 - 3 = 3
The largest value for the second plot is 10
So the difference for the second plot is 10 - 7 = 3
This means the variation quadrial is bigger for the red plot, but the difference beetween the points is equal.

Consider the following equation. Graph 5x + 6y = 30
PLEASE SHOW STEPS
Answer:
Step-by-step explanation:
Convert the equation into slope-intercept form.
5x-6y =30 Subtract 5x from each side
-6y = -5x + 30 Multiply each term by -1
6y = 5x – 30 Divide each side by 6
y = ⅚x - 5
2. Create a table of different x and y values,
x ⅚x – 5 y
-12 ⅚(-12) – 5 -15
-6 ⅚(-6) – 5 -10
0 ⅚(0) – 5 -5
6 ⅚(6) – 5 0
12 ⅚(12) – 5 5
3. Convert the table to ordered pairs
(-12,-15)
(-6, -10)
(0, -5)
(6, 0)
(12, -5)
4. Plot the points and draw a line through them.

What is the volume of figure A in the composite figure?
Answer:
30 in
Step-by-step explanation:
subtract 5 inches from 8 inches and you get 3 inches (the height)
then we already have the given 4 inches (the width)
then finally we can see from figure b that the depth is 5 inches
you multiply all of them together and get 60, before dividing that in half to get 30.

y = -3x + 18
3x + y = 18
if a +b+c = 0 then the value of a²+b²+c²/bc+ca+ab
pls solve and give the explanation
Answer:
[tex]\frac{a^2 + b^2 +c ^2}{a*b + a*c + b*c} = -2[/tex]
Step-by-step explanation:
if:
a + b + c = 0
then we can rewrite:
c = -a - b
Now we can replace this in our expression:
[tex]\frac{a^2 + b^2 + c^2}{a*b + a*c + b*c} = \frac{a^2 + b^2 + (-a - b)^2}{a*b + a*(-a - b) + b*(-a - c)}[/tex]
Now we can rewrite:
(-a - b)^2 = a^2 + 2*a*b + b^2
Then we can rewrite our expression as:
[tex]\frac{a^2 + b^2 + a^2 + b^2 + 2*a*b}{a*b - a^2 - a*b - b^2 - b*a}[/tex]
Let's keep simplifying this:
[tex]\frac{2*(a^2 + b^2 + a*b)}{-a*b - b^2 - a^2}[/tex]
Here is easy to see the simplification we need to do, as we have the same factor in the denominator as in the numerator (just a different of sign).
[tex]\frac{2*(a^2 + b^2 + a*b)}{-a*b - b^2 - a^2} = \frac{2*(a^2 + b^2 + a*b)}{-(a^2 + b^2 + a*b)} = -2[/tex]
Then the expression is equal to -2
[tex]\frac{a^2 + b^2 +c ^2}{a*b + a*c + b*c} = -2[/tex]

Which expression shows how to find the area of the figure? What is the area of the figure?
Answer:
42 cm squared
Step-by-step explanation:
For part 1, separate the figure into two squares. The 6's are there to trick you, so we won't be using them for the entire process while solving this problem. The bright side is that you won't trick the 6's yourself. Heh. Once doing that, you should get 9 X 4 + 2 X 3, which would be C according to the choices shown.
For part 2, simply do order of operations, or PEMDAS. Here's what PEMDAS stands for:
Parenthesis
Exponents
Multiply/Divide from the left to the right
Add/Subtract from the left to the right
You MUST do this IN ORDER! No exceptions!
Multiply 9 by 4, then multiply 2 by 3.
After that, you should get 36 and 6. Add them together, and you'll get your final answer, which would be 42 cm squared.
So, the final answer would be 42 cm squared.

A researcher investigated the relationship between alcohol intake and reaction time in a driving simulation task. Participants drank either one ounce or three ounces of alcohol and were then measured on braking speed at a simulated red light. The independent variable was the
Answer:
Alcohol intake
Step-by-step explanation:
The Independent variable also called the predictor variable may be described as the treatment which is given a subject or factors which is expected to induce a change in our measured variable which is called the predicted or dependent variable. During research, the test various factors which are expected to cause a change are the independent variable, whereas, the variable which is measured as a result of the changes caused due to the different independent variables is the dependent variable. In the scenario above, we wish to measure braking speed after the subjects have been given a certain ounce of alcohol, this ounce of alcohol is the treatment which is expected to cause a variation in the braking speed of the participants. Hence, alcohol intake is the independent variable while braking speed is the dependent variable.

Good Luck!
The required value of x for the given equation is approximately 1.71.
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
Equation:
The given equation is [tex]10(1.5)^{3x} = 80[/tex]
Divide both sides by 10.
[tex](1.5)^{3x} = \dfrac{80}{10}\\\\(1.5)^{3x} = 8[/tex]
Taking log on both sides, we get
[tex]log (1.5)^{3x} = log 8\\\\3x log (1.5) = log 8[/tex]
Divide both sides by 3log(1.5).
x = log 8/ 3log(1.5)
x = 1.71
Therefore, the required value of x for the given equation is approximately 1.71.

Which is a perfect square?
Answer:
I believe it's 6^2.
Step-by-step explanation: 6^2 is the same as 6 times 6. Here's a tip, if you see a 2 as an exponent, you can also say x squared. X to the power of 2 is the same as x squared.
Answer:
[tex]6^{2}[/tex]
Step-by-step explanation:
[tex]6^{1}[/tex] = 6 [tex]\sqrt{6}[/tex] = 2.45 (NOT a perfect square)
[tex]6^{2}[/tex] = 36 [tex]\sqrt{36}[/tex] = 6 (perfect square)
[tex]6^{3}[/tex] = 216 [tex]\sqrt{216}[/tex] = 14.7 (NOT a perfect square)
[tex]6^{5}[/tex] = 7776 [tex]\sqrt{7776}[/tex] = 88.18 (NOT a perfect square)
If the answer ends with a decimal, they are not perfect squares.

Answer:
21 feet²
Step-by-step explanation:
To find the area of a composite figure, we can break the shape into pieces and solve for the area separately.
There are multiple ways to separate the figure, but for this explanation we will break it into two rectangles, 5×3 and 3×2.
The area of a rectangle can be found by multiplying the length and width of the shape. So for the left rectangle, we will multiply 5 by 3.
5 · 3 = 15
The area of our first rectangle is 15 ft².
Next, we will find the area of the right rectangle, by multiplying 3 by 2.
3 · 2 = 6
The area of the second rectangle is 6 ft².
Now we can add the areas, 15 and 6, together to find the total area.
15 + 6 = 21
The area of the figure is 21 ft².
I hope this helps ^^ Good luck ∩_∩

Find the equation of a line that passes through (5.3) and (4,5).
Answer:
y=-2x+13
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-3)/(4-5)
m=2/-1
m=-2
y-y1=m(x-x1)
y-3=-2(x-5)
y=-2x+10+3
y=-2x+13
How do I write -x + 2y= -4 in slope intercept form
Answer:
ok so slope intercept for is y=mx+b, or y=slope x + y intercept. Sooo it would be y=0.5x-2 :) hope this helps
Step-by-step explanation:
Answer:
y = 1/2 x - 2
Step-by-step explanation:
Slope-intercept form:
y = mx + b
You need to solve for y.
-x + 2y = -4
2y = x - 4
y = 1/2 x - 2
An aquarium tank that measures 2.4 meters high, 6 meters long, and 1.5 meters wide is completely filled with water. The density of water is 1,000 kilograms per cubic meter. What is the mass of the water in the tank?
A:46 kilograms
B.101 kilograms
C.9,900 kilograms
D.21,600 kilograms
Answer:
D.21,600 kilograms
Step-by-step explanation:
The volume of the tank is Length x Width x Height (6*1.5*2.4)
So the volume is 21.6 cubic meters.
Therefore, there are 21.6 cubic meters of water.
The density of water is 1,000 kg per cubic meter. So multiply 1,000 to the number of cubic meters. (1,000*21.6)
The mass of the water in the tank is 21,600 kg
Length = 4
Width = ?
Area = 60
