The staircase has three identical parallelogram-shaped panels. The horizontal distance between each panel is 4.25 inches. The area of each panel is 287 square inches. What is the value of x ?
Answers
*see attachment for diagram
Answer:
x = 20.5 in.
Step-by-step explanation:
What we are requested to find is the height of the panel/parallelogram = x
Area of each panel = base × height = 287 in.²
Given that the total length of the 3 panels which includes the length of the 2 gaps within them = 50.5 in., first, let's find the base length of each panel.
Base length of each panel = (total length - length of the 2 gaps in between the 3 panels) ÷ 3
= (50.5 - 2*4.25) ÷ 3
= 42 ÷ 3
Base length of each panel = 14 in.
✔️Next is to find the height of the panel, x.
area of parallelogram = base × height
Base = 14 in.
height = x
Area = 287 in.²
Plug in the values
287 = 14 × x
287 = 14x
Divide both sides by 14
287/14 = x
20.5 = x
x = 20.5 in.

14. Given that log 2 = 0.3010 and log 3 = 0.4771 , how can we find log 6 ?
A. log6 = log2 x log3 = 0.3010 x 0.4771
B. log6 = log2 + log3 = 0.3010 + 0.4771
C. log6 = log2 – log3 = 0.3010 – 0.4771
D. log6 = log2 = log3 = 0.3010 = 0.4771
Answers
Answer:
B. log6 = log2 + log3 = 0.3010 + 0.4771
Step-by-step explanation:
log 2 = 0.3010
log 3 = 0.4771
log 6 = ?
6 = 3 * 2
log 6 = log (3 * 2)
According to log rules;
log (a * b) = log(a) + log (b)
This means;
log 6 = log 3 + log 2
Inserting the values they represent;
log 6 = log 3 + log 2 = 0.4771 + 0.3010
Correct option:
B. log6 = log2 + log3 = 0.3010 + 0.4771

Answer:
X = 78, Z = 29, and Y = 102
Step-by-step explanation:
X = 78. 43 + 59 = 102. There has to be 180 degrees in a triangle. So subtract 180 by 102.
Z = 29. Think of the whole triangle for this one. 43 + 49 + 59 = 151. 180 - 151 = 29.
Y = 102. Plug in the value of Z. 49 + 29 = 78. 180 - 78 = 102.

The mean and the standard deviation of the data set is 5.2 and 3.429.
What is Arithmetic Mean?The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.
We have,
Data: {5, 8, 1, 2, 10}.
So, the mean of data
= (5+ 8 + 1 + 2 +10)/ 5
= 5.2
Then, the Value of Deviations
-0.2, 2.8, -4.2, -3.2, 4.8
So, the variance is
= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5
= 11.76
And, Standard deviation is
= 3.429

Answer:
Step-by-step explanation:
495. I just took it 100%
The measure is of an angle that is coterminal with a 135° angle is,
⇒ 495°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
The angle is,
⇒ 135°
Now, To find the coterminal angle add 360 to the given angle as;
⇒ 360 + 135
⇒ 495°

Answers
Respuesta:

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

Answer:
10.3
Step-by-step explanation:
The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.
[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]
We find the square root of both sides to find the value of c.
10.295 ≈ c
Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3
