Answer:
P = (8T) / V
Step-by-step explanation:
P*V=8*T*P/P multiply both sides by P
P*V=8*T because P/P=1
P = 8T/V divide both sides by V

1) Triangle T1 is transformed into triangle T2 by
a. dilation with scale factor of 1/2
b. reflection over the y-axis
c. translation
2) and triangle T2 is transformed into trinagle T3 by
a. dilation with scale factor 1/2
b. reflection over the x-adis
c. rotation
Answer:
1) The correct option is;
b. Reflection over the y-axis
2) The correct option is;
a. Dilation by a scale factor of 1/2
Step-by-step explanation:
1) The rule for reflection over the y-axis is given as follows;
Given the point of the preimage before the reflection = (x, y), the point of the image after the reflection will be (-x, y)
The coordinate of a point on T1 is (-2, 4). The coordinate of similar point in T2 is (2, 4) which satisfies the rule for reflection over the y-axis
2) The length of a side in triangle T2 is given by the formula for finding the length, l, of segments between coordinate points as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Point 1, (x₁, y₁) = (2, 4)
Point 2, (x₂, y₂) = (6, 2)
The length = √((2 - 4)² + (6 - 2)²) = 2·√5
The length of the corresponding side in T3 is given as follows;
Point 1, (x₁, y₁) = (1, 2)
Point 2, (x₂, y₂) = (3, 1)
The length = √((1 - 2)² + (3 - 1)²) = √5
The length of of a side T3 = 1/2 of the length of a side of T2
Therefore. triangle T2 is transformed into triangle T3 by dilation with a scale factor of 1/2.

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0

The total number of miles, d, Elise walks in n hours can be modeled by the equation d = ns. Her rate stays the same each hour. Which represents the number of miles Elise walks per hour?
Answer:
Step-by-step explanation:
Given the number of miles Elise walks in n hiurs modeled by the equation;
d = ns
The number of miles he walks per hour is expressed by substituting n =1 into the equation to have;
d = ns
d = (1)s
d = s
Hence the number of miles he walked per hour is expressed as d = s

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!

Step-by-step explanation: bc angel 3 is 80 that means angel 2 is one hundred and abc is the same as angel tow because the two lines are so ABC is 100 and line segment BC is bisecting ABC so you divide ABC by two and get 50
this line? 10. A line passes through the points (-3, -1) and (-5, 4). What is the slope of this line?
Answer:
-4/7
Step-by-step explanation:
To calculate slope, you should put your points into this form - (y1-y2)/(x1-x2). In this case, it's (-5+1)/(4+3).
