Answer:
B (-2, 2)
Step-by-step explanation:
The midpoint equation is:
[tex]x \frac{}{m} = \frac{x \frac{}{2} + x \frac{}{1} }{2} [/tex]
[tex]y \frac{}{m} = \frac{y \frac{}{2} + y \frac{}{1} }{2} [/tex]
Then:
[tex]x \frac{}{1} = 2x \frac{}{m} - x \frac{}{2} [/tex]
[tex]y \frac{}{1} = 2y \frac{}{m} - y\frac{}{2}[/tex]
[tex]x \frac{}{1} = 2( - 4) - ( - 6) \\x \frac{}{1} = - 8 + 6 \\ x \frac{}{1} = - 2[/tex]
[tex]y \frac{}{1} = 2(2) - 2 \\ y \frac{}{1} = 4 - 2 \\ y \frac{}{1} = 2[/tex]
Determine whether this equation has no solution, one solution, or infinitely many solutions
8p + 1 = 4p +2
Answer:
the equation has one solution, p = 1/4
Step-by-step explanation:
8p + 1 = 4p + 2
subtract 4p from both sides of the equation
8p - 4p + 1 = 4p - 4p + 2
8p - 4p + 1 = 2
4p + 1 = 2
subtract 1 from both sides of the equation
4p + 1 - 1 = 2 - 1
4p = 2 - 1
4p = 1
divide both sides of the equation by 4
4p/4 = 1/4
p = 1/4

Do 9, 11, 12, 13
PLEASE GIVE ALL DETAILS
Answer:
The answer is below
Step-by-step explanation:
9) The area of the platform = length * width = 9 m * 12 m = 108 m²
Area = 108 m²
11) 1 km² = 1 km × 1 km = 1000 m × 1000 m = 1000000 m²
But 1 hectare = 10000 m², hence:
1000000 m² = 1000000 m² / 10000 m² per hectare = 100 hectares
1 km² = 100 hectares
12) Area of each paper = 16 cm * 12 cm = 192 cm²
There are 48 sheets, hence:
Total area of sheets = 192 cm² * 48 = 9216 cm²
13) Area of each tile = 12 cm * 10 cm = 120 cm²
The kitchen contains 500 tiles, therefore:
Area of kitchen = 120 cm² * 500 tiles = 60000 cm²
1 m² = 10000 cm²
60000 cm² = 60000 cm² / 10000 cm² per m² = 6 m²
Area of kitchen = 6 m²
Compare A and B if 70% of A is equal to $0.7a and 35% of B is equal to $0.35a
Please help! I'm stumped
Answer:
A=B
Step-by-step explanation:
Equation 1: 70% of A = 0.7a
Equation 2: 35% of B = 0.35a
Equation 3 = (Equation 2) • 2
Equation 3: 70% of B = 0.7a
Equation 3 = Equation 1
A = B
The required solution of the given condition is A = B.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
70% of A = 0.7a
A = 0.7 / 0.7a
A = a - - - - (1)
Now,
35% of B = 0.35a
B = 0.35 / 0.35a
B = a - - - - - (2)
From equation 1 and 2
A = B
Thus, the required solution of the given condition is A = B.

Give Nitroprusside 5 mcg/kg/minute via continuous infusion for a patient weighing 205 lbs. Nitroprusside is available in a solution of 200 mg in 250 mL D5W. What rate on the infusion pump will deliver the correct dose?
Answer:
35 ml/hr
Step-by-step explanation:
Convert lbs to kg
205 ÷ 2.2 = 93.18 = 93.2 kg
Calculate the minute rate
93.2 kg x 5 mcg/kg/min = 466 mcg/min
Calculate hourly rate
466 mcg/min x 60 mins/hr = 27,960 mcg/hr
Drug is expressed in mg, so convert mcg to mg
27,960 mcg = 27.96 mg

The measure of angle ADB = 59 degrees
The measure of angle DEC = 118 degrees
Step-by-step explanation:
BD = 2 * EC = 2 * 13 = 26
The measure of angle ADB = 90 - 31 = 59 degrees
The measure of angle DEC = 180 - 2(31) = 180-62 = 118 degrees

Steve decreased the number of miles he ran from 25 to 18 . By what percent did the number of miles decrease
Answer:
Percentage decrease = 28%
Step-by-step explanation:
Original distance = 25 miles
New distance = 18 Miles
Change in distance = 25 - 18
= 7 miles
Percentage decrease = change in distance / original distance × 100
= 7/25 × 100
= 0.28 × 100
= 28%
Percentage decrease = 28%
If i roll 2 dice what is the probability that both of them are prime and even?
Answer:
[tex]\frac{1}{36}[/tex]
Step-by-step explanation:
Think of the possibilities of #s each dice can roll: 1 - 6. Only 2 is prime and even meaning that's only one of six possibilities. Since rolling two dice are two subsequent events, multiply the probabilities which should be exactly the same. [tex]\frac{1}{6} *\frac{1}{6}=\frac{1}{36}[/tex]

A line has a slope of 1 and passes through the point (13,1) What is its equation in slope intercept form?
Answer:
y = x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1 , then
y = x + c ← is the partial equation
To find c substitute (13, 1) into the partial equation
1 = 13 + c ⇒ c = 1 - 13 = - 12
y = x - 12 ← equation of line

Pipe A can fill a tank in 5 hours. Pipe B can fill it in 2 hours less time than it takes pipe C, a draining pipe, to empty the tank. With all 3 pipes open, it takes 3 hours to fill the tank. How long will it take pipe C to empty it?
Answer: Time taken by pipe C to empty the tank = 5 hours.
Step-by-step explanation:
Pipe A can fill a tank in 5 hours.
Let time taken by Pipe C = x ( hours)
Time taken by Pipe B = x-2 ( hours)
Now, with all 3 pipes open, it takes 3 hours to fill the tank, it can be represented as
[tex]\dfrac15+\dfrac1{x-2}-\dfrac1x=\dfrac 13\\\\\Rightarrow\ \dfrac{x-(x-2)}{x(x-2)}=\dfrac13-\dfrac15\\\\\Rightarrow\ \dfrac{x-x+2}{x^2-2x}=\dfrac{5-3}{15}\\\\\Rightarrow \dfrac{2}{x^2-2x}=\dfrac2{15}\\\\\Rightarrow\ x^2-2x=15\\\\\Rightarrow\ x^2-2x-15=0\\\\\Rightarrrow\ x^2-5x+3x-15=0\\\\\Rightarrow\ x(x-5)+3(x-5)=0\\\\\Rightarrow\ (x-5)(x+3)=0\\\\\Rightarrow\ x=5, -3[/tex]
Time cannot be negative,
So, x=5
Thus, Time taken by pipe C to empty the tank = 5 hours.

What is the measure of the angle marked y?
Answer:
y = 48°
Step-by-step explanation:
In parallelogram STVU,
[tex] m\angle TVU + 60\degree = 180\degree[/tex] (linear pair angles)
[tex] m\angle TVU = 180\degree - 60\degree [/tex]
[tex] m\angle TVU = 120\degree [/tex]
[tex] m\angle UST= m\angle TVU =120\degree [/tex](Opposite angles of a parallelogram)
[tex] m\angle USR= 120\degree(\because S-R-T) [/tex]
[tex] 108\degree + m\angle USR+m\angle PSR= 360\degree[/tex]
[tex] 108\degree + 120\degree+m\angle PSR= 360\degree[/tex]
[tex] 228\degree + m\angle PSR= 360\degree[/tex]
[tex] m\angle PSR= 360\degree - 228\degree [/tex]
[tex] m\angle PSR= 132\degree [/tex]
[tex] y+m\angle PSR= 180\degree [/tex]
(Adjacent angles of a parallelogram)
[tex] y+ 132\degree= 180\degree [/tex]
[tex] y= 180\degree-132\degree[/tex]
[tex] y= 48\degree[/tex]
How many acute angles does a heptagon have?
Answer:
4 side is the answer I am sure
Answer:
None.
Step-by-step explanation:
I assume we are talking about a regular heptagon.
This has 7 sides and 7 internal angles.
Each internal angle = 180 - (360/7) = 128.6 degrees which is an obtuse angle.

the product of age of a person 10 year ago and 10 year after is 156.find
Answer:
The age of the person now is 16 years old
Step-by-step explanation:
Let us solve the question
Assume that the age of the person now is x years old
∵ The age of the person now is x years old
∵ His age 10 years ago = x - 10
∵ His age 10 years after = x + 10
∵ The product of his ages 10 years ago and 10 years after is 156
→ Multiply his ages before and after and equate the product by 156
∴ (x - 10)(x + 10) = 156
∵ (x - 10)(x + 10) = (x)(x) + (x)(10) + (-10)(x) + (-10)(10)
∴ (x - 10)(x + 10) = x² + 10x - 10x - 100
→ Add the like terms
∴ (x - 10)(x + 10) = x² + (10x - 10x) - 100
∴ (x - 10)(x + 10) = x² - 100
→ Substitute it in the equation above
∵ x² - 100 = 156
→ Add 100 to both sides
∴ x² - 100 + 100 = 156 + 100
∴ x² = 256
→ Take √ for both sides
∴ √x² = √256
∴ x = 16
∵ x represents his age now
∴ The age of the person now is 16 years old
