Answer:
x=7
Step-by-step explanation:
4(5x-2)=2(9x+3) do everything in the parentheses
20x-8=18x+6
+8 +8
20x=18x+14
get X by itself by adding same terms
20x=18x+14
-18x -18x
2x=14 divide
/2 /2
X=7
write an algebraic expression: The product of 6.3 and g increased by 14
Answer:
6.3g + 14
Step-by-step explanation:
The product of 6.3 and g:
6.3*g = 6.3g
The product of 6.3 and g increased by 14
⇒ 6.3g increased by 14
6.3g + 14
The volume of a right cylinder is 27π cubic centimeters, and the high is 3 centimeters (cm). What is the radius of the cylinder?
A. 2 Cm
B. 3 Cm
C. 4.5 cm
D. 9 Cm
Answer:
B
Step-by-step explanation:
The volume is the height x area of base, 27pi / 3 = 9pi
Area of base is radius square x pi, 9 pi = 3^2 x pi
The radius of a cylinder with volume of 27π is 3 centimetres.
How to solve for volume of a cylinder?volume of a cylinder = πr²h
where
r = radiush = heightTherefore,
r = ?
h = 3 cm
volume = 27π
Hence,
27π = π × r² × 3
divide both sides by 3π
r² = 27π / 3π
r² = 9
r = √9
r = 3 cm

A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.
Complete the equation for the relationship between the thickness and number of weeks.
y=__________
Hi there!
Let the equation be
[tex]y = kx + b[/tex]
When x = 0, y = 2
And
when x = 3, y = 1.25
So, b = 2
3k + b = 1.25
=> k = -0.25
b = 2
Therefore, y = -0.25x + 2 (Substituting the two points)

=================================================
Explanation:
mu = population mean = 1300
sigma = population standard deviation = 20
Compute the z score based on x = 1330
z = (x-mu)/sigma
z = (1330-1300)/20
z = 30/20
z = 1.5
Asking to compute P(X < 1330) is the same as P(Z < 1.5) in this specific context when mu = 1300 and sigma = 20.
Use a Z table or a calculator to find that P(Z < 1.5) is roughly 0.93319
About 93.319% of the 755 bulbs are expected to last less than 1330 hours.
0.93319*755 = 704.55845
That value rounds to 705

Answer:
1) 5.20 if rounded
2) 123.04 if rounded
3) 16.17 if rounded
Step-by-step explanation:
1) tan (30) = x/9
x = tan (30) (9)
x = 5.1961... (5.20 if rounded)
2) sin (25) = 52/x
x = 52/sin(25)
x = 123.0424... (123.04 if rounded)
3) cos (18) = x/17
x = cos (18) (17)
x = 16.1679... (16.17 if rounded)

A new book is being planned. It will have 24 pages of introduction. Then it will have c 12-page chapters and 48 more pages at the end.Write a rule that represents the total number of pages p in the book as a functional of the number of chapters.Suppose the book has 25 chapters.How pages will it have?
Answer:
Let the number of pages be y and the number of chapters be x, then y = 24 + 12x + 48 = 12x + 72
y = 12x + 72
If the book has 25 chapters, the number of pages will be y = 12(25) + 72 = 300 + 72 = 37 pages.

Find the missing side lengths the triangle is 30-60-90
Answer:
y= 4

The mode of five numbers is 1 ; the median is 5 and the mean is 4. Find the numbers.
Does anyone know what number 7 is I’m very confused.
Answer: [tex]\huge\boxed{5 \text{ prices}}[/tex]
Step-by-step explanation:
Because the mean is simply the mathematical average of all the points, simply add all the prices and divide by the amount of prices, or 10.
100 + 150 + 80 + 240 + 130 + 170 + 210 + 165 + 275 + 90 = 1610, then divide by 10 to get 1610 / 10 = 161.
Because there is a absolute deviation of 50 from the mean, simply subtract and add fifty to learn that the least they will pay is $111, and the most they will pay is $211, and 5 prices fall within this range.

Answer:
30a - 18
Step-by-step explanation:
What's the distributive property?
The distributive property is a property of math that helps with multiplication, usually in the form a(b + c). When using this property, a number, a, is distributed to the terms inside the parentheses, like b and c.Given the information above, let's simplify 6(5a - 3).
[tex](6)(5a) + (6)(-3)[/tex] [tex]30a - 18[/tex]Therefore, the answer is 30a - 18.

find the equation of a parabola with a vertex of (2,8) and passes through the point (10,-4)?
Answer:
[tex]\displaystyle y = -\frac{3}{16}\, (x - 2)^{2} + 8[/tex].
Step-by-step explanation:
In general, if the vertex of a parabola is [tex](h,\, k)[/tex] (where [tex]h[/tex] and [tex]k[/tex] are constants,) the equation of that parabola would be [tex]y = a\, (x - h)^{2} + k[/tex] for some constant [tex]a[/tex] ([tex]a \ne 0[/tex].) This equation is the vertex form equation of this parabola.
In this question, it is given that the vertex of this parabola is [tex](2,\, 8)[/tex]. Thus, [tex]h = 2[/tex] and [tex]k = 8[/tex]. The equation of this parabola would be [tex]y = a\, (x - 2)^{2} + 8[/tex] for some constant [tex]a[/tex].
Finding the value of this constant [tex]a[/tex] requires the coordinates of a point on this parabola other than the vertex [tex](2,\, 8)[/tex].
Since [tex](10,\, -4)[/tex] is a point on this parabola, [tex]x = 10[/tex] and [tex]y = (-4)[/tex] should satisfy the equation of this parabola [tex]y = a\, (x - 2)^{2} + 8[/tex].
Thus:
[tex](-4) = a\, (10 - 2)^{2} + 8[/tex].
Solve this equation for [tex]a[/tex]:
[tex]\displaystyle a = -\frac{3}{16}[/tex].
Thus, the equation of this parabola in vertex form would be:
[tex]\displaystyle y = -\frac{3}{16}\, (x - 2)^{2} + 8[/tex].
