5 (a - 1) - 15 = 3 (a + 2) + 4
Solution :[tex] \sf \dashrightarrow \: 5 (a - 1) - 15 = 3 (a + 2) + 4 [/tex]
[tex]\sf \dashrightarrow \: 5 \times a - 5 \times 1 - 15 = 3 \times a + 3 \times 2 + 4 [/tex]
[tex]\sf \dashrightarrow \: 5 a - 5 - 15 = 3 a + 6 + 4 [/tex]
[tex]\sf\dashrightarrow \: 5 a - 20 = 3 a + 10 [/tex]
[tex]\sf\dashrightarrow \: 5 a - 20 - 3a - 10 = 0 [/tex]

Hence, value of a = 15.A ring-shaped region is shown below.
Its Inner radius is 11 cm, and its outer radius is 17 cm.
Find the area of the shaded region. Use 3.14 for pi. Do not round your answer.
Answer:
527.52 cm²
Step-by-step explanation:
Area of the shaded region = area of the outer circle - area of the inner circle
Area of circle is given as πr²
Radius of inner circle = 11 cm
Area of outer circle = 17 cm
π = 3.14
Thus:
Area of shaded region = 3.14*17² - 3.14*11²
= 907.46 - 379.94
= 527.52 cm²

Calculate the length of the diagonal AB
Answer:
AB = [tex]5\sqrt{3}[/tex] cm
Step-by-step explanation:
The diagonal of the bottom square is the hypotenuse of two right triangles with legs 5 and 5
So, the length of that diagonal, say x, of a 45-45-90 triangle where x is the hypotenuse is x = [tex]5\sqrt{2}[/tex]
Now that diagonal is a leg of the right triangle where AB is the hypotenuse and 5 is the length of the other leg.
So, [tex]x^{2} + 5^{2} = AB^{2}[/tex] = [tex](5\sqrt{2} )^{2}[/tex] + 25
= 50 + 25
= 75
Therefore AB = [tex]\sqrt{75}[/tex] = [tex]5\sqrt{3}[/tex]

Answer:
28/x=34
28/34=x
x=0.825is the required answet
Answer:
x = 17/14
Step-by-step explanation:
28 * x = 34
x * 28 = 34
Let's divide by 28 on both sides:
x = 34/28
Let's simplify by dividing both 34 and 28:
x = 17/14
17 is a prime number, so we can't simplify any further.
x = 17/14
f(x) = -x - 4
g(x) = 2x^2 + 4x + 11
Find: (f*g)(x)
Answer:
f(x)*g(x) = [tex]-2x^{3} - 12x^{2} - 27x - 44[/tex]
Step-by-step explanation:
I am assuming that * means multiplication
(f*g)(x) = f(x)*g(x)
So, f(x)*g(x) = (-x-4)([tex]2x^{2} + 4x + 11[/tex]) = [tex]-2x^{3} - 4x^{2} - 11x - 8x^{2} - 16x - 44[/tex]
= [tex]-2x^{3} - 12x^{2} - 27x - 44[/tex]
2/6 blue socks 2/6 green socks and the rest are white socks what would the answer be
Answer:
I think ita would be 2/6 as well
Step-by-step explanation:
simplify it down to 1/3 and the blue take up one third and so does the green socks
Answer:
2/6 socks are white.
Step-by-step explanation:
The denominator (6) is the amount of socks you have.
If 2/6 are blue and 2/6 are green. 4/6 are Blue & Green.
To find the remaining amount of socks you would simply subtract 6/6 by 4/6
That would leave you with 2/6 of the socks being WHITE.
Hope this helps you!! <3
A large operator of timeshare complexes requires anyone interested in making a purchase to first visit the site of interest. Historical data indicates that 55% of all potential purchasers select a day visit, 25% choose a one-night visit, and 20% opt for a two-night visit. In addition, 10% of day visitors ultimately make a purchase, 25% of night visitors make a purchase, and 20% of those visiting for two nights make a purchase. Suppose a visitor is randomly selected. What is the probability that the visitor makes a purchase
Answer:
0.1575 = 15.75% probability that the visitor makes a purchase
Step-by-step explanation:
We have these following probabilities:
55% probability that a visitor selects a day visit, and in this case, 10% probability of making a purchase.
25% probability that a visitor chooses a one-night visit, and in this case, 25% probability of making a purchase.
20% probability that a visitor chooses for a two night visit, and in this case, 20% probability of making a purchase.
What is the probability that the visitor makes a purchase
[tex]p = 0.55*0.1 + 0.25*0.25 + 0.2*0.2 = 0.1575[/tex]
0.1575 = 15.75% probability that the visitor makes a purchase

What is the decimal value of ⅖. Use factors of 2 and 5 to convert fraction into decimal. :
What is the decimal value of 5/25. Use Equivalent Fractions to convert fraction into decimal. :
Answer:
0.4 and 0.2.
Step-by-step explanation:
For the first problem, you divide 5 by 2.
[tex]\frac{2}{5} = 0.4.[/tex]
This gives you 0.4
For the second problem, we simplify the fraction, first.
[tex]\frac{5}{25} = \frac{1}{5} .[/tex]
Then, we divide 1 by 5.
[tex]\frac{1}{5} = 0.2.[/tex]
This gives you 0.2.
Using SOLVE, determine the number of marbles that are in a large cylindrical flask as depicted in the handout from Lesson 1. Solve by hand (or electronically) and clearly outline your individual steps. (Sketch, Organized Variables, List Egns, Vary eqns, Evaluate). Embed a photo of your work below. Click the linke, for instructions to embed. Use the following variables for your evaluate step and stay in Sl units. Diameter of Marble - 13 mm Diameter of Flask - 25 cm Height of Flask (to level of marbles) - 40 cm FYI: 10 mm -1 cm
Given :
Diameter of the flask = 25 cm
radius, r = [tex]$\frac{25}{2}$[/tex] cm
Height of the flask, h = 40 cm
We have to find out the volume of the cylinder flask
Volume [tex]$= \pi r^2h$[/tex]
[tex]$= 3.14 \times (\frac{25}{2})^2 \times 40$[/tex]
= [tex]$19634.95 \ cm^3$[/tex]
= [tex]$19635 \ cm^3$[/tex]
Now calculate the volume of the marble
Given :
Diameter = 13 mm
radius, R [tex]$=\frac{13}{2} \ mm$[/tex]
Therefore, volume of the marble [tex]$=\frac{4}{3}\pi R^3$[/tex]
[tex]$=\frac{4}{3}\times 3.14 \times (\frac{13}{2})^3$[/tex]
[tex]$= 1150.35 \ mm^3$[/tex]
or [tex]$= 115.035 \ cm^3$[/tex]
Therefore, the number of the marbles [tex]$=\frac{\text{volume of flask}}{\text{volume of marble}}$[/tex]
[tex]$=\frac{19635}{115.035}$[/tex]
= 170.68
Therefore, the number of the marbles used is approximately 170.
