What is the area of triangle ABC?
A(2,1) B(4,7) C(6,3)
Answer: 10
Step-by-step explanation:
It appears that [tex]\overline{AC} \perp \overline{BC}[/tex], so to check if this is the case, we can use the slope formula.
[tex]m_{\overline{AC}}=\frac{3-1}{6-2}=\frac{1}{2}\\m_{\overline{BC}}=\frac{3-7}{6-4}=-2[/tex]
Since these slopes are negative reciprocals, we can see that this is the case. So, we can take [tex]\overline{AC}[/tex] as the base of the triangle and [tex]\overline{BC}[/tex] as the height of the triangle, and then use the formula [tex]A=\frac{1}{2}bh[/tex].
Using the distance formula,
[tex]AC=\sqrt{(6-2)^{2}+(3-1)^{2}}=\sqrt{16+4}=2\sqrt{5}\\BC=\sqrt{(4-6)^{2}+(7-3)^{2}}=\sqrt{4+16}=2\sqrt{5}[/tex]
So, the area is [tex]\frac{1}{2}(2\sqrt{5})(2\sqrt{5})=\boxed{10}[/tex]
In a year, a hospital admitted 4500 patients. If of the patients had heart or lung diseases,
how many patients had heart or lung diseases?
Answer:
4500
Step-by-step explanation:
all of them were admitted.
6/(x^2-3x)=12/x+1/(x-3)
[tex]\\ \rm\Rrightarrow \dfrac{6}{x^2-3x}=\dfrac{12}{x}+\dfrac{1}{x-3}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{6}{x(x-3)}=\dfrac{12}{x}+\dfrac{1}{x-3}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{6}{x(x-3)}=\dfrac{12(x-3)+x}{x(x-3)}[/tex]
[tex]\\ \rm\Rrightarrow 6=12x-36+x[/tex]
[tex]\\ \rm\Rrightarrow 6=13x-36[/tex]
[tex]\\ \rm\Rrightarrow 13x=42[/tex]

Step-by-step explanation:
The longest string length is 12 3/4 (12.75)
The two shortest string lengths are 3 and 4 1/4 (4.25)
combine the length of the tow shortest string by adding them together,
3 + 4.25 = 7.25
to find how much longer the longest string you subtract the two numbers,
12.75 - 7.25 = 5.5
Triangle MRN is created when an equilateral triangle is folded in half.
Triangle N R M is shown. Angle N R M is a right angle. An altitude is drawn from point R to point S on side M N to form a right angle. The length of N S is 6, the length of S M is 2, the length of R M is x, the length of N R is y, and the length of R S is z.
What is the value of y?
The value of y based on the values given ib the equilateral triangle will be 4.
How to illustrate the triangle?From the information given, MN is one of the sides of the equilateral triangle. Therefore, side MR will be:
= 1/2 × 8 = 4
In the above, it should be noted that MR was calculated since it's half of the value of MN which is 8.
Here, value of y based on the values given ib the equilateral triangle will be 4.

A patient is to take 7 mL of amoxicillin 250 mg/5 mL. How many milligrams?
Step-by-step explanation:
that means that in 5 ml there are 250mg.
and that means that in 1 ml there are 250/5 = 50 mg.
and now we can find out the mg in 7 ml (by multiplying everything by 7) :
7 ml = 50 × 7 = 350 mg

The value of x is x = 10
To solve a first degree equation, first: we add or subtract like terms. Finally, we split the terms of both equalities.
- In this equation, we're going to subtract the like terms -- and on the other side of the equation, we're going to also subtract the real terms.
Resolution15 + 2x = 5 + 3x
2x - 3x = 5 - 10
-1x = -10
x = 10
So, the correct value is x = 10

Using the vertically opposite angles theorem and corresponding angles theorem, we have proven that alternate exterior angles are congruent
Angle theoremsFrom the question, we are to prove that alternate exterior angles are congruent.
In the given diagram, examples of alternate exterior angles are
∠1 and ∠8
∠2 and ∠7
Now, we will prove that ∠1 = ∠8
In the diagram, we can observe that
∠1 = ∠4 (Vertically opposite angles theorem)
and
∠4 = ∠8 (Corresponding angles theorem)
Then,
By the substitution property of equality
∠1 = ∠8
Hence, alternate exterior angles are congruent

What is the value of x in the triangle?
Answer:
D
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 4[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 2[tex]\sqrt{2}[/tex]
What is the solution to this system of equations? 2x+y-5z=4 x+3y+z=5 3x-y-4z=-11
For the given linear system equations, the value for the variables are: x=-2, y=4, and z=-5 - Option C.
System of Linear Equations
System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.
The question gives:
2x+y-5z=4 (1)
x+3y+z=5 (2)
3x-y-4z=-11 (3)
First, you should sum equations 1 and 2. The results will be:
3x+4y-4z=9 then you have a new equation (4).
3x-y-4z=-11 (3)
3x+4y-4z= 9(4)
Now, you should multiply equation (3) by -1, then you will have:
-3x+y+4z=+11 (3)
3x+4y-4z=9 (4)
After that, you should sum the previous equations: (3) and (4).
5y=20
y=4
For find z, you should multiply equation 2 by -2. After that, you should sum equations 1 and 2.
2x+y-5z=4 (1)
-2x-6y-2z=-10 (2)
Thus, you will have:
-5y-7z=-6, like y=4 you have
-5*4-7z=-6
-20-7z=-6
-7z=14
z=-2
If z=-2 and y=4 from equation 2, you can find x.
x+3y+z=5
x+3*4-2=5
x+12-2=5
x+10=5
x=5-10
x=-5

Hello!
We know that b>6, and we are asked to find the possible values for 3b + 3.
Let's directly substitute 6 for b:
3(6) + 318 = 321Now, because b is greater than 6, and not equal to 6, any value greater than 21 will work.
