PLEASE HELP ME TO ANSWER THIS QUESTION.

A right pyramid PQRST has a rectangular base QRST. Given
that W is the midpoint of QS and RT, the lengths of QT = 8 cm,
TS = 6 cm and point P is vertically above point W, calculate
(a) PT, in cm, if PW = 12 cm
(b) the value of < PTR [angle PTR]

THANK YOU!!!​

Answers

Answer:

(a) PT = 13 cm

(b) <PTR = [tex]39.7^{o}[/tex]

Step-by-step explanation:

(a) Applying the Pythagoras theorem to QST, we have;

[tex]QS^{2}[/tex] = [tex]ST^{2}[/tex] + [tex]QT^{2}[/tex]

      = [tex]6^{2}[/tex] + [tex]8^{2}[/tex]

[tex]QS^{2}[/tex] = 36 + 64

       100

QS = [tex]\sqrt{100}[/tex]

     = 10

QS = 10 cm

Since QS = TR, then;

WT = [tex]\frac{1}{2}[/tex] TR

      = [tex]\frac{1}{2}[/tex] x 10

WT = 5 cm

Thus, applying Pathagoras theorem to PWT;

[tex]PT^{2}[/tex] = [tex]PW^{2}[/tex] + [tex]WT^{2}[/tex]

      = [tex]12^{2}[/tex] + [tex]5^{2}[/tex]

      = 144 + 25

[tex]PT^{2}[/tex] = 169

PT = [tex]\sqrt{169}[/tex]

    = 13

PT = 13 cm

(b) To determine <PTR, TR = 10 cm. Apply the required trigonometric function;

Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]

Cos θ = [tex]\frac{10}{13}[/tex]

          = 0.7692

θ = [tex]Cos^{-1}[/tex] 0.7692

  = 39.7179

θ = [tex]39.7^{o}[/tex]

Therefore, <PTR = [tex]39.7^{o}[/tex]

The 4th grade class experienced a 15% decrease in enrollment. Last year, the 4th grade class had 280 students. How many students are enrolled in the 4th grade class this year?

Answers

There are a lot of ways to solve this, but here is a simple one. 15% reduction gets you 85%, or 0.85 in decimal form. So you now know that this year’s 4th grade class is going to be 85% or 0.85 of what it was last year (280). Just multiply 280*0.85. 238 is your answer.

Answer: 238

Step-by-step explanation: 15% of 280 is 42 so subtract 42 from the number and it equals 238

A bag contains 9 red, 7 blue, and 4 yellow marbles. If a marble is chosen at random from the bag, what is the probability that it is NOT yellow? (in fraction form) A) 1 5 B) 1 3 C) 3 5 Eliminate D) 4 5

Answers

Answer:

D

Step-by-step explanation:

if you add all the numbers together you get a total of 20. if you add the non yellow marbles together you get 16. so the fraction is 16/20. then you shorten the fractions by dividing the numbers. both are divisible by 4, so the final answer is 4/5.

Can someone please help me with my homework its due in two hours!!!!!! Please i need it done soon.

Answers

Answer:

see explanation

Step-by-step explanation:

so, when a=-3, c is -20. now, to find b when a is -3, plug a (which is -3) into the equation b=4a-5 to get b=-17. so b=-17, c=-20. b is obviously larger (remember the negative sign)

when c is 21, a is 5. plug numbers in to get b=15.

when a is 6, there is no clear value for c, so i'd guess undefined. b however is 19

we can plot the line and the points, for problem 4 and all points above the line means that c is greater than b, and when below it's less than. doing this we get when a is 12, when a is 0, and when a is 5. hope this was clear

The only solution to x^2+bx+c=0 is x=5 find a and b

Answers

Answer:

b=-10

c=25

Step-by-step explanation:

if the only solution is 5 so

x^2+bx+c=(x-5)²=x²-10x+25

b=-10

Help me find this perimeter please

Answers

Answer:

52 in

Step-by-step explanation:

I added all the sides I already know which is 10+5+5+16= 36

then to find the sides we don't know I subtracted part of the side we do know from the full side we do know for example I subtracted 5 from 10 and 5 from 16 to get 5 and 11 as the missing sides then I added those to the 36 so final answer is 52 in

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side is 6 more than the shortest side. What are the lengths of the triangle?

Answers

Answer:

7, 9, 13

Step-by-step explanation:

Let the sides of the triangle be a, b and c.

We have:

P = a + b + c = 29a = 2b - 5c = b + 6

Substitute values and solve for b:

2b - 5 + b + b + 6 = 294b + 1 = 294b = 28b = 7

Find a and c:

a = 2*7 - 5 = 14 - 5 = 9c = 7 + 6 = 13

The sides are: 7, 9, 13
