Given :
A triangular prism .To Find :-
The total surface area of the prism .Solution :-
From the given figure we can see that the prism is made up of
2 triangular surfaces .3 rectangular surfaces .And the base and height of each triangle is ,
base = 7 inch height = 5 inchAnd the dimensions of each rectangle is ,
length = 13 inchbreadth = 6.1 inchTherefore , the Total surface area is ,
→ TSA = 2( area of each ∆) +3(area of each rectangle)
→ TSA = 2 ( 1/2 * 7 * 5)in.² + 3(13*6.1) in.²
→ TSA = 2 * 35/2 in.² + 3* 79.3 in.²
→ TSA = 35 in.² + 237.9 in.²
→ TSA = 272.9 ≈ 273 in.²
Hence the TSA of prism is 273 in.² .

f(x)=4x-6
g(x) = f(2x)
Substitute 2x into the first equation, which you get
f(2x)=8x-6
So, g(x)=8x-6A class votes for their class president

Find two numbers whose sum is 15 and difference is 3.
Answer:
The two numbers are 6 and 9
Step-by-step explanation:
Let the two numbers be x and y
x+y = 15
x-y = 3
Add the two equations together to eliminate y
x+y = 15
x-y = 3
----------------
2x = 18
Divide by 2
2x/2 = 18/2
x = 9
Now we can find y
x+y = 15
9+y = 15
y = 15-9
y = 6
The two numbers are 6 and 9

A. 10-oz. box
B. 14-oz. box
Answer:
b 14oz .box
Step-by-step explanation:
10 oz cost 1.86
1 oz is .19 cents
14 oz cost 2.61
1 oz is .19 cents
so the for one oz is .19 cents for both of them

1. OP ≈ QR
2. P is the midpoint of OR
3. OQ+QP=QP + PR
4. PQ≈ PR
The required statement that is true for the given circle is PQ = PR. Option D is correct.
What is a circle?A circle is a closed shape consisting of all points in a plane that are at a constant distance from a single fixed point called the center. The distance between the center and any point on the circle is called the radius, and the distance across the circle, passing through the center, is called the diameter.
Here,
From the figure,
QP = PR,
So P is the midpoint of QR,
Thus, the required statement that is true is PQ = PR. Option D is correct.

The line L1 is defined Ax + By = 3. The line L2 is defined by the equation Ax + By = 2. The line
L3 is defined by Bx − Ay = 1. Determine whether L1, L2 and L3 are parallel or perpendicular to each other.
Step-by-step explanation:
Line 1: Ax+By=3
By=-Ax+3
-> slope is -A/B
Line 2: Ax+By=2
By=-Ax+2
-> slope is -A/B
Line 3: Bx-Ay=1
Ay=Bx-1

probability that the letter is
a. A ‘‘t’’.
b. An ‘‘o’’ or an ‘‘m’’.
c. An ‘‘x’’.
d. A vowel.
with solution please asap
Step-by-step explanation:
a=> let t denote the number of t
n(t)=1
number of total letters, n(s) = 8
Now,
probability of getting t ,P(t)
= n(t)/ n(s)
= 1/8
b=> let o denote the number of o and
m
n(o)=2
number of total letters, n(s) = 8
Now,
probability of getting t ,P(o)
= n(o)/ n(s)
= 2/8
= 1/4
c=> let x denote the number of x
n(x)=0
number of total letters, n(s) = 8
Now,
probability of getting a x, P(x)
= n(x)/n(s)
= 0/8
= 0
d=> let v denote the number of vowel
letters
n(v)=3
number of total letters, n(s) = 8
Now,
probability of getting a vowel

Question 4 (Essay Worth 10 points)
(06.05 MC)
Gina spins a penny 100 times and it lands head side up 38 times. Explain why Gina's experimental probability may be different from the theoretical probability of
spinning a coin
The random nature of the process is why Gina doesn't get the theoretical probability. If she were to repeat this experiment say 1000 or perhaps 10,000 times, then her experimental probability value should get closer to 1/2. It likely won't land *exactly* on 1/2 because again of the random nature of the outcomes.
For more information, check out the Law of Large Numbers.
Answer:
The theoretical probability of spinning a head = 1/2 = 0.5
Therefore, if Gina spins a penny 100 times, the theoretical number of times it will land head side up = 0.5 x 100 = 50 times
Gina's experimental probability is 38/100 = 0.38
Therefore, the experimental probability is less than the theoretical probability.
The main difference between experimental and theoretical probability is that experimental probability is based on the actual results of an experiment (gathered by experimenting repeatedly), whereas theoretical probability is based on possible outcomes based on assumptions.
If Gina continued to spin the penny, as the number of times she spun it increased, you would expect for the experimental probability to get nearer to the theoretical probability of 0.5.

On many cell phones with GPS, an approximate location can be given before the GPS signal is received. This is done by a process called triangulation, which works by using the distance from two known points. Suppose there are two cell phone towers within range of you, located 6000 feet apart along a straight highway that runs east to west, and you know you are north of the highway. Based on the signal delay, it can be determined you are 5050 feet from the first tower, and 2420 feet from the second. Determine the angle, , between your line of sight to the first tower and the highway to the nearest tenth of a degree. (A calculator is needed for this question)

Jane and Eric are helping their teacher buy supplies for a research project. Every student will get a bag with 2 pencils and 30 index cards.
The teacher gave Jane $17 to buy pencils from the school store. The pencils come in boxes of 12 and cost $1.69 per box.
Eric was given $19 to buy index cards at an office supply store. Index cards are sold in packs of 150 cards and cost $2.99 per pack.
Jane buys as many boxes of pencils as she can afford. Eric buys as many packages of index cards as he can afford. How many complete bags of supplies can they make?
Answer:
They can make 30 Bags total.
Step-by-step explanation:
Jane has $17. There are 12 pencils in each pack for $1.60.
Jane can bay 10 packs of 12 pencils for $16.9 or else she will go over the amount of money she has.
1.69 x 10 = 16.9
Eric has $19. There are 150 cards in one pack for $2.99.
Eric can bay 6 packs of 150 cards for $17.94 or he ill go over the amount of money he has.
2.99 x 6 = 17.94
Eric.
150^6 = 900
900/30 = 30
Jane.
12^10 = 120
120/2 = 60
60/2 = 30
Together.
30 cards can go into 30 bags, and 2 pencils can go into 30 bags

From the quadratic equation 3x² + X - 5 = 0, find alpha square plus beta square
Answer:
α² +β² = 3 4/9
Step-by-step explanation:
Assuming α and β are solutions to the equation, it can be factored as ...
(x -α)(x -β) = 0
Expanding this, we get ...
x² -(α +β)x +αβ = 0
Dividing the original equation by 3, we find ...
x² +(1/3)x -5/3 ≡ x² -(α+β)x +αβ ⇒ (α+β) = -1/3, αβ = -5/3
We know that the square (α+β)² can be expanded to ...
(α +β)² = α² +β² +2αβ
α² +β² = (α +β)² -2αβ . . . . . . subtract 2αβ
Substituting the values for (α+β) and αβ, we find the desired expression is ...
α² +β² = (-1/3)² -2(-5/3) = 1/9 +10/3 = 31/9
α² +β² = 3 4/9
A carpenter makes $24/hour and works a 40 hour week. The employer withholds $83 federa
tax, $74 FICA, and $41 state tax. The carpenter's take-home pay is
Answer:
762
Step-by-step explanation:
Since he makes 24 dollars a hour and he worked for a total of 40 hours that'll equal to 960 and when you subtract all the taxes away from his payment it'll equal to 762
The net income of the carpenter will be $762.
What is net income?
The amount paid by any company or industry to the employees after deductions of the several taxes is the net income.
Given that:-
A carpenter makes $24/hour and works a 40 hour week.The deductions are $83 federal tax, $74 FICA, and $41 state tax.So the net income of the carpenter will be calculated as:-
Gross pay will be = 24 x 40 = $960
Net income = 960 - ( 83 + 74 + 41 ) = $762
Hence the net income of the carpenter will be $762.
