The volume of the triangular prism clay pot is 195 unit³
Volume of a triangular prism:v = BHwhere
B = base area
H = height of the prism
Therefore,
Base area = area of a triangle
area of a triangle = 1 / 2 × base × height
Therefore,
B = 1 / 2 × b × h
b = 3 units
h = 5 units
B = 1 / 2 × 3 × 5
B = 15 / 2
B = 7.5 units²
Therefore,
H = 26 units
B = 7.5 units²
V = 7.5 × 26
V= 195 unit³

Answer:
y= -2x+1
Step-by-step explanation:
The slope of the line is -4/2, which gets simplified to -2. Then, the line passes through y-intercept (0,1), which becomes +1 as the y-intercept in y=mx+b form. Therefore, the equation is y= -2x+1. I'm 100% sure this is right. Hope that helps :)
solve system of equations:
-2x + y = 5
-4x + 3y = 7
answer:
(x,y)=( -4, -3)
Answer:
{x,y}={-4,-3}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x + 5
// Plug this in for variable y in equation [2]
[2] -4x + 3•(2x+5) = 7
[2] 2x = -8
// Solve equation [2] for the variable x
[2] 2x = - 8
[2] x = - 4
// By now we know this much :
x = -4
y = 2x+5
// Use the x value to solve for y
y = 2(-4)+5 = -3
Solution :
{x,y} = {-4,-3}

We know line segment BD is parallel to line segment AE. Which of the following statements must also be true (select two choices)
The statement that must be true about the two similar triangles based on the triangle similarity theorem is: option 2 and option 3.
What is the Triangle Similarity Theorem?The triangle similarity theorem states when a segment intersects the other two sides of a triangle, and the segment is parallel to the third side, then the two triangles formed are similar, and the corresponding sides are proportional to each other.
Given that line segment BD is parallel to line segment AE, therefore, triangles CBD and CAE are similar triangles, their corresponding angles are congruent, while their corresponding sides are proportional.
Therefore, the statement that must be true about the two similar triangles based on the triangle similarity theorem is: option 2 and option 3.

5. A girl walks north 750 m in 10 minutes. What is her velocity?
Explanation:
Divide the distance (750) over the time (10) to get the speed
750/10 = 75
The velocity is made up of the speed and the direction. Therefore, her velocity is 75 meters per minute north. For each minute, she moves another 75 meters north.
what are the roots of the equation x^2 +30x =1000?
Answer:
x=20 and x=-50
Step-by-step explanation:
To find the roots, we need to simply solve for x. We do this by first moving all of the terms to the left and setting the right side equal to 0.
-1000
x^2+30x-1000=0
Now, factor it.
What adds up to 30 but multiplies to get -1000?
-10 and 40? No, because they multiply to get -400.
-20 and 50? Yes, because they add up to 30 and multiply to get -1000.
(x-20)(x+50)
x-20=0
x=20
x+50=0
x=-50
So, the roots are x=20 and x=-50

So on converting the equation in standard form ,
[tex] x^2+30x -1000=0[/tex]
With respect to the standard form ,
a = 1b = 30c = -1000Substitute in the Quadratic formula ,
[tex] x =\dfrac{-30\pm \sqrt{(30)^2-4(1)(-1000)}}{2(1)}[/tex]
Simplify,
[tex] x =\dfrac{-30\pm\sqrt{900+4000}}{2}[/tex]
Add the numbers inside square root ,
[tex] x =\dfrac{-30\pm\sqrt{4900}}{2}[/tex]
Divide each term in numerator by 2,
[tex] x =\dfrac{-30}{2}\pm\dfrac{\sqrt{70^2}}{2}[/tex]

Mai and Tyler work on the equation 2 5 b + 1 = - 11 together. Mai's solution is b = - 25 and Tyler's is b = - 28 . Here is their work:
Mai:
2 5 b + 1 = - 11
2 5 b = - 10
b = - 10 ⋅ 5 2
b = - 25
Tyler:
2 5 b + 1 = - 11
2 b + 1 = - 55
2 b = - 56
b = - 28
Do you agree with their solutions? Explain or show your reasoning.
Answer:
I do not agree with the solutions, b=-30, reasoning below.
Step-by-step explanation:
Mai made an error between the first and second line, she added one to the right when she should have subtracted one:
2/5b+1=-11
2/5b=-12
She then multiplied by 5/2 which was correct, however she multiplied it by -10 when it should have been -12:
b=-12*5/2
b=-30
Tyler made an error between the first and second line when he did not multiply the 1 on the left by 5 also:
2/5b+1=-11
2b+5=-55
He did the next steps correctly, however he had the incorrect value, it should look like this:
2b=-60
b=-30

Step-by-step explanation:
Squaring the given equation gives
[tex]t^2+(2\cdot t \cdot \frac{1}{t} )+ \frac{1}{t^2}=9.[/tex]
The [tex]t[/tex] and [tex]\frac{1}{t}[/tex] terms cancel out nicely, which is one of the reasons for squaring the equation.
Simplifying gives
[tex]t^2+2+\frac{1}{t^2}=9,[/tex]
[tex]t^2+\frac{1}{t^2}=7.[/tex]
The question asks for [tex]t^5+\frac{1}{t^5},[/tex] so we can square the equation again and simplify to get higher powers into the expression:
[tex](t^2+\frac{1}{t^2})^2=49,[/tex]
[tex]t^4+(2 \cdot t^2 \cdot \frac{1}{t^2}) + \frac{1}{t^4}=49,[/tex]
[tex]t^4+2+ \frac{1}{t^4}=49,[/tex]
[tex]t^4+\frac{1}{t^4}=47.[/tex]
Multiplying this expression by [tex]t+\frac{1}{t}[/tex] to try and get a fifth power gives
[tex](t^4+\frac{1}{t^4})(t+\frac{1}{t})=t^5+t^3+\frac{1}{t^3}+\frac{1}{t^5}.[/tex]
The only thing left we need is [tex]t^3+\frac{1}{t^3}[/tex] to subtract from this; we know everything else. Since [tex]t^3+\frac{1}{t^3}[/tex] can be written as [tex](t+\frac{1}{t})(t^2-1+\frac{1}{t^2}),[/tex] we can simply plug in the values we know for [tex]t+\frac{1}{t}[/tex] and [tex]t^2+\frac{1}{t^2}:[/tex]
[tex]t^3+\frac{1}{t^3}=(3)(7-1)=18.[/tex]
All that is left is to plug it in our equation here:
[tex](t^4+\frac{1}{t^4})(t+\frac{1}{t})=t^5+t^3+\frac{1}{t^3}+\frac{1}{t^5},[/tex]
[tex](47)(3)=t^5+\frac{1}{t^5}+18,[/tex]
Multiplying and rearranging gives:
[tex]t^5+\frac{1}{t^5}=123.[/tex]

The Gomez family ordered $39.50 worth of
pizza and subs. They gave the delivery person
a 20% tip. What was the total cost of the food
and tip? Roun to the nearest cent?
Step-by-step explanation:
To find the cost of the tip, we need to find 120% of 39.50.
120% = 100% (order) + 20% (tip)
Let's use fractions. 39.50 can be put over 1, and 120 can be put over 100.
Equation:
[tex]\frac{39.50}{1} \times \frac{120}{100} =?[/tex]
Multiply:
[tex]\frac{39.50}{1} \times \frac{120}{100} =\frac{4740}{100}[/tex]
Divide 4740 and 100 by 100:

The total cost of the food is $47.40.
Wayne Gretzky holds the NHL record for the most points scored in a career. He scored 2857 points in 1487 games.
a) Calculate his average points per game.
b) At this rate, how many more points would he have scored if he had played 79 more games.
Answer:
1999 The most points scored in an NHL career is 2,857, achieved by Wayne Gretzky (Canada) while playing for the Edmonton Oilers (Canada), Los Angeles Kings, St Louis Blues and New York Rangers (all USA) from 1979 to 1999. The points total comprises 894 goals and 1,963 assists in 1,487 games.
Step-by-step explanation:
a) Wayne Gretzky's average points per game is approximately 1.9202.
b) Wayne Gretzky would have scored approximately 151.5438 more points if he had played 79 more games.
a) To calculate Wayne Gretzky's average points per game, we divide the total points scored (2857) by the total number of games played (1487):
Average points per game = Total points scored / Total games played
Average points per game = 2857 / 1487 ≈ 1.9202
Wayne Gretzky's average points per game is approximately 1.9202.
b) To find out how many more points Wayne Gretzky would have scored if he had played 79 more games, we can use the average points per game calculated in part (a).
We know that his average points per game is approximately 1.9202. So, to find the additional points in 79 games, we can multiply the average points per game by the number of additional games:
Additional points = Average points per game * Additional games
Additional points = 1.9202 * 79 ≈ 151.5438
Wayne Gretzky would have scored approximately 151.5438 more points if he had played 79 more games.
