Answer:
relationship between perpendicular and base is given by tan angle
tanx°=p/b
tanx°=45/30
x°=tan-¹(45/30)=56.30=56
Answer:
0.03
Step-by-step explanation:
In given triangle,
perpendicular(p)=45
base(b)=30
x=?
We know,
tanx = p/b
or, tanx = 45/30
or, tanx = 3/2
or, x = tan-1(9/7)
or, x = 56.3099324740202 i.e. 56 approximately

Answers
Answer:
Part A
y = 8
Part B
We can find BF by either;
a) Through Pythagoras theorem to find the length of a side in a right triangle
b) The known rate of change of the length of the line FC with height
Step-by-step explanation:
Part A
The given parameters are;
FC = 5
We are to find BF
By the triangle proportionality theorem, we have;
FC:BF = EC:AE
From the given draining we have;
C(10, 2), F(7, 6), B(5.5, y), E(4, 2), A(1, 2)
Points A, E and C are have the same y-coordinate values, therefore, we have;
EC = 10 - 4 = 6
AE = 4 - 1 = 3
Therefore, we have;
5/BF = 6/3 = 2
BF = 5/2 = 2.5
Using the formula for finding the distance between two points, we have;
BF = √((5.5 - 7)² + (y - 6)²)
BF² = 2.5² = (5.5 - 7)² + (y - 6)²
6.25 = 2.25 + (y - 6)²
6.25 - 2.25 = 4 = (y - 6)²
√4 = √(y - 6)² = (y - 6)
±2 = y - 6
y = 6 + 2 = 8, or y = 6 - 2 = 4
Given that from the diagram, y > 6, we have y = 8
Part B
a) To find BF we can use the Pythagoras's theorem given that we know the coordinates of B and F as follows;
BF = √((5.5 - 7)² + (8 - 6)²) = 2.5
b) Given that BF is on the same straight line as FC, BF can be found through the rate of change of the y-values with the length of the line
We can also find BF by using proportion of increase in 'Δy' to the length of the line BFC as follows;
From point C to point F, Δy = 6 - 2 = 4 and the length of the line FC = 5
Therefore, from point B to point F, Δy = 8 - 6 = 2, ∴ BF = 2 × 5/4 = 2.5

The length of adult King Cobra snakes is normally distributed with µ = 18 feet and σ = 2.1 feet. What is the probability that a randomly selected adult King Cobra snake be over 15.9 feet long? 85.54% 79.08% 15.87% 84.13%
Answers
Answer:
the probability that a randomly selected adult King Cobra snake be over 15.9 feet long is 84.13%
Step-by-step explanation:
The computation of the probability is shown below":
P(x>15.9) is
[tex]= P (\frac{x - \mu}{\sigma} > \frac{15.9 - 18}{2.1} )\\\\= P (z>-1)\\\\= 0.8413\\\\= 84.13\%[/tex]
Hence, the probability that a randomly selected adult King Cobra snake be over 15.9 feet long is 84.13%
We simply applied the above formula
Answer:
the probability that a randomly selected adult King Cobra snake be over 15.9 feet long which is 84.13%
Step-by-Step Explanation:
P(X 15.9). Solve for the z-score and then match it with the probability from the area under the normal curve table. Once that is found, take the complement or use symmetry to solve

If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k
Answers
Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k
Dos hermanos reciclaron la misma cantidad de kilos de papel que de envases de carton. Se pagan 183 por cada kilo de papel y 356 por cada kilo de carton y con lo que juntaron lograron ganar 3763.
Answers
Respuesta:
183x + 356y = 3763
Explicación paso a paso:
Dejar :
Número de kilos de papel = x; número de kilos de cartón = y
Kilo de papel = 183; kilo de cartón = 356
Cantidad total ganada = 3763
(Costo por kilo de papel * número de kilos de papel) + (costo de kilos de cartón * número de kilos de cartón)
(183 * x) + (356 * y) = 3763
183x + 356y = 3763

What is the formula for VOLUME?
V
What is the VOLUME of the STONE? Remember to LABEL answer
Answers
Answer:
Formula for volume = length (L) × width (W) × height (H)
Volume of the stone = 1,440 cm³
Step-by-step explanation:
✔️Formula for the rectangular tank = L*W*H
✔️Volume of the stone = volume of the tank with the stone - volume of the tank without the stone
✔️Volume of the tank with the stone:
L = 30 cm, W = 24 cm, H = 8 cm (height of water when the stone was in the tank)
Volume of the tank with the stone = 30*24*8 = 5,760 cm³
✔️Volume of the tank without the stone:
L = 30 cm, W = 24 cm, H = 6 cm (height of water when the stone was pulled out)
Volume of the tank with the stone = 30*24*6 = 4,320 cm³
✅Volume of the stone = 5,760 - 4,320 = 1,440 cm³

Answer:
Number of hours= 20 hours
Step-by-step explanation:
Giving the following information:
Net savings (babysitting)= 250 - 110= $140
Rate per hour= $7
To calculate the number of hours that Melissa worked as a babysitter, we need to use the following formula:
Number of hours= net savings / rate per hour
Number of hours= 140 / 7
Number of hours= 20 hours
