Find the total surface area of this triangular prism.
24 cm
25 cm
10 cm
14 cm
If the picture below is your triangular prism..
Answer:
976
Step-by-step explanation:
14 x 24 = 336 [It's a triangle you would half it but then as there are 2 you would keep it the same]
10 x 25 = 250 [Times by 2 because there are 2 of them]
10 x 14 = 140
336 + 250 + 250 + 140 = 976

What is the vertex of g(x) = 3x2 − 12x + 7?
(−6, −5)
(−2, −5)
(2, −5)
(6, −5)
Answer:
(2, -5)
Step-by-step explanation:
Convert to vertex form:
3x^2 - 12x + 7
= 3(x^2 - 4x) + 7
Completing the square:
= 3[ (x - 2)^2 - 4)] + 7
= 3(x - 2)^2 - 12 + 7
= 3(x - 2)^2 - 5.
Comparing with the general form
a(x - b)^2 + c we see that the vertex is (b, c) = (2, -5).

if a bloodstain has a length of 3.0cm and a width of 1.5cm what is the angle of impact?
The angle of impact is 30°
What is the angle of impact?In a bloodstain, the angle of impact can be used to determine the appearance of the resulting bloodstain if the bloodstain has a tail or pattern.
Bloodstain pattern analysis is the study of bloodstains at a scene of the crime in an attempt to reconstruct the events that resulted in the bloodshed.Mathematically;
[tex]\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{width \ stain}{length \ stain} )}[/tex]
[tex]\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{1.5}{3.0} )}[/tex]

If somebody offered to give me £20 if I give them £10, have I actually made a profit?
From my point of view, no as you're giving them £10 for £20 which basically gives the £20 a value of £10 which in no profit. However, I may just not be thinking about it right and if it is incorrect inform me.
I am only asking this as my family says you have gained £10.
Answer:
Yes, you have made a profit.
Step-by-step explanation:
Basically, profit just means that you end up having more money than you started with.
Since you started with 10 and got a 20 in exchange for it, you now have 10 dollars more than you previously did, meaning you made a profit.
Find the length of the third side. If necessary, write in simplest radical form. 10 9
Answer:
3[tex]\sqrt{10}[/tex] = x
Step-by-step explanation:
This is a right triangle and in right triangles the sum of square length of two legs is equal to square length of hypotenuse.
Now let x represent the third side:
9^2 + 10^2 = x^2
81 + 100 = x^2
181 = x^2 find the root for both sides
3[tex]\sqrt{10}[/tex] = x

Find P(4.7≤x≤5.3)=??
Answer:
P(4.7≤x≤5.3)≈0.6827≈68.27%
Step-by-step explanation:
Notice that 4.7 is 1 standard deviation below the mean (μ) and 5.3 is 1 standard deviation above the mean. Thus, by the Empirical Rule, ±1σ represents about 68.27% of the data in a normal distribution, meaning that P(4.7≤x≤5.3)≈0.6827

Is this a parallelogram

Step-by-step explanation:
5x + 2 + 3x = 8x + 2
3 + 17x + 8 = 17x + 11
19 + 6x + 2x = 8x + 19
14x + 7 + 4 = 14x + 11
9x - 3 - 7x + 4 = 2x + 1
12x + 3x - 6 - 7f = 15x - 7f - 6
14x + 7 - 3x = 11x + 7
13z + 6u + 8x + 19 - u = 13z + 5u + 8x + 19
3z + 6 + 4z + 9 + 8u = 7z + 8u + 15
2x + 8z + 13u + 6z + 4u = 2x + 14z + 17u
14y + 13x + 12y + 19x + 4 = 26y + 32x + 4
5x + 18 - 13y + 12x + 8y = 17x - 5y + 18
21v + 8 - 12v - 7 + 3t - t = 9v + 2t + 1
3t + v - t + 7v = 2t + 8v

A marathon runner is able to run 15 miles in 3 hours. write an equation that relates the number of miles, y, to the number of hours, x.
Answer:
5y = x
Step-by-step explanation:
15 miles = 3 hours
Divide by 3 on both sides to find how many miles he/she can run in 1 hour.
15 miles = 3 hours ⇒ 5 miles = 1 hour
Therefore, the equation is just 5y = x.
