Answer:
14x^2-21?.…....………...
Answer:
14x^2 -21
Step-by-step explanation:
Think About the Process If you solve the linear system by adding to eliminate p, which step could you do first? Solve for p and q.
2p +39 = 7
3p + 59 = 10
Which step could you do first?
O A. Multiply the first equation by - 3 and the second equation by - 2.
O B. Multiply the first equation by 3 and the second equation by 2.
O c. Multiply the first equation by - 3 and the second equation by 2.
OD. Multiply the first equation by - 2 and the second equation by 3.
The solution is
(Type an ordered pair.)
Answer:
(23, -1)
Step-by-step explanation:
I think you meant 2p + 39q = 7 , & 3p + 59q = 10
You would do C first, because that will get rid of the P's.
---> -6p - 117q = -21
---> 6P + 118q = 20
Now we get q=-1
If we plug it into the first equation, we get 2p + 39(-1) = 7
Therefpre, 2p - 39 = 7. This means that 2p = 46.
Therefore, p = 23
(23, -1)

Find the value of x
Answer:
66
Step-by-step explanation:
EHG is a straight line so it is 180°.
You already know the value of FHG, so you can find the value of 2x.
180° = 48° + 2x
2x = 180° - 48°
= 132
x = 132° ÷ 2
= 66
Answer:
66 should be the answer.
Step-by-step explanation:
2x + 48 = 180
2x + 48 - 48 = 180 - 48
2x = 132
2x ÷ 2 = 132 ÷ 2
x = 66

Richard deposits $193.67 every month into his mortgage. At the end of 30 years, he has a balance of $120,182.07. What interest has accrued (been earned) over 30 years?
Answer:
50,460.87
Step-by-step explanation:
To do this we first need to figure out how much he deposited without any interest to do this we do 193.67*12 to find out how much he deposited per year, then we multiply this number by 30 to find out how much he deposited in total. After finding this we subtract this number from the total balance to calculate the interest

What is the range of the data set?
Answer:
Range = 19
Step-by-step explanation:
Range = maximum value - minimum value
Maximum value is indicated by the whisker to our far right on a box plot = 25
Minimum value is at the whisker to our far left = 6
Range = 25 - 6 = 19

cos(alpha + pi/3) = (sqrt(3))/2
Answer:
α = -2 π n_1 - π/2 for n_1 element Z
or α = -2 π n_2 - π/6 for n_2 element Z
Step-by-step explanation:
Solve for α:
sin(-α + π/6) = sqrt(3)/2
Hint: | Eliminate the sine from the left hand side.
Take the inverse sine of both sides:
-α + π/6 = 2 π n_1 + (2 π)/3 for n_1 element Z
or -α + π/6 = 2 π n_2 + π/3 for n_2 element Z
Hint: | Look at the first equation: Isolate terms with α to the left hand side.
Subtract π/6 from both sides:
-α = 2 π n_1 + π/2 for n_1 element Z
or -α + π/6 = 2 π n_2 + π/3 for n_2 element Z
Hint: | Solve for α.
Multiply both sides by -1:
α = -2 π n_1 - π/2 for n_1 element Z
or -α + π/6 = 2 π n_2 + π/3 for n_2 element Z
Hint: | Look at the second equation: Isolate terms with α to the left hand side.
Subtract π/6 from both sides:
α = -2 π n_1 - π/2 for n_1 element Z
or -α = 2 π n_2 + π/6 for n_2 element Z
Hint: | Solve for α.
Multiply both sides by -1:
Answer: α = -2 π n_1 - π/2 for n_1 element Z
or α = -2 π n_2 - π/6 for n_2 element Z

Answer:
-3
Step-by-step explanation:
Please take a look at the question. Please explain and type your explaination. Please make it quick as possible. Thankyou!
Answer:
Yes, it's true
Step-by-step explanation:
A fraction is a part of a whole number for example 1/2. 1/2 is a half of one whole piece and if you multiply it into any whole number whether it's 2,4,6,8,10...... basically, if you multiply a fraction less than one with a non-zero whole number, it will always be less than the whole number it's being cut into smaller pieces. However, if the fraction is greater than 1, we would technically have an answer greater than the whole number product, just something to remember.

Answer:
b = 5.7
A = 51.1°
B = 38.9°
Step-by-step explanation:
a = 7
c = 9
✔️Find b using Pythagorean theorem:
b = √(9² - 7²) ≈ 5.7
✔️Find A using trigonometric function:
Reference angle = A
Opposite = a = 7
Hypotenuse = c = 9
Apply SOH:
[tex] sin(A) = \frac{Opp}{Hyp} [/tex]
[tex] sin(A) = \frac{7}{9} [/tex]
[tex] A = sin^{-1}(\frac{7}{9}) [/tex]
A = 51.0575587° = 51.1°
✔️B = 180 - (90 + 51.1) (sum of triangles)
B = 38.9°
g During winter, red foxes hunt small rodents by jumping into thick snow cover, without any visual clue. Researchers examined the compass direction of hundreds of such jumps. They found that 73% of jumps in the northeast direction were successful, compared with 60% of jumps in the southwest direction and only 18% of jumps in all other directions. True or False: Jumping direction and jump outcome are independent.
Answer: False
Step-by-step explanation:
Events can be classed as being dependent or independent depending on whether the outcome of a certain event affects the outcome of another. In the scenario above, the success rate of jumps in the Northeast direction is higher than in the southwest direction and even much than in other directions. With these uneven rate of success, the probability that a fox will have a successful jump will depend on the direction in which the fox is jumping. With an high expected success probability in the Northeast and southwest than in other directions

16. A rock weighs 6 and 1/2 tons. How many pounds does the rock weigh?
2,000 lb = 1 T
Answer:
13000
Step-by-step explanation:
1 = 2,000 pounds
0.5 tons = 1000 pounds
Answer: 13,000 lb
Step-by-step explanation:
6 x 2,000 = 12,000
1/2 * 2,000 = 1,000
12,000 + 1,000 = 13,000

Billy wants to buy these tickets for a show: 4 adult tickets at £15 each and 2 child tickets at £10 each. A 10% booking fee is added to the ticket price. 3% is then added for paying by credit card. Work out the total charge for these tickets when paying by credit card.
Answer:
The total charge for these tickets when paying by credit card is £ 90.64.
Step-by-step explanation:
Since Billy wants to buy 4 adult tickets at £ 15 each and 2 child tickets at £ 10 each for a show, and a 10% booking fee is added to the ticket price, and 3% is then added for paying by credit card, for work out the total charge for these tickets when paying by credit card the following calculation must be performed:
((4 x 15 + 2 x 10) x 1.10) x 1.03 = X
((60 + 20) x 1.10) x 1.03 = X
(80 x 1.10) x 1.03 = X
88 x 1.03 = X
90.64 = X
Thus, the total charge for these tickets when paying by credit card is £ 90.64.

Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
Vertical/ x = 25.
Step-by-step explanation:
Vertical angles are self-explanatory; vertical angles are angles that are vertical from each other.
Vertical angles are also congruent (equal), meaning that both angles equal 75°.
4x - 25 = 75.
To solve this expression, we must first add 25 to 75. This is because there is a subtraction sign in front of 25, so we must do the opposite.
25 + 75 = 100
Lastly, divide 100 from 4.
4x = 100
100 / 4 = 25
x = 25
