Question:4 × (2a - 1)
Given value:a = 3
Solution:4 × (2a - 1)
= 4 × (2(3) - 1) [Substituting the value of a=3]
= 4 × (6 - 1) [Simplification]
= 4 × 5 [On further simplification]
= 20
Hence, 20 is the required answer.
Answer:
20
Step-by-step explanation:
a = 3
4 × (2a - 1) =
= 4 × (2 × 3 - 1)
= 4 × (6 - 1)
= 4 × 5
= 20

Hello,
A.i. the circumference of a circle is nothing else but its perimeter which formula is π × diameter = π × 2 × radius
Let π = 22/7 ≈ 3.142857, the egyptian approximation
Then if C is the circumference of the circle i., C = 22/7 × 21 = (22 × 21) / 7 = (22× 7×3 )/7 = 22 ×3 = 66 cm
ii. Applying the same formula for the second circle gives us C = 22/7 × 8 = 176/7 ≈ 25.14 meters, rounded to the nearest hundredth...
Good luck !
Answer:
a) 66cm. b) 50.28cm. or 50 2/7cm.
Step-by-step explanation:
The circumference of a circle is C=2πr or C=πd.
π=22/7
a) C=πd
Plugin the diameter.
C=22/7 x 21
=66cm.
b) C=2πr
Plugin the radius.
C=2 x 22/7 x 8
=50.28cm. or 50 2/7cm.
Hope this helps :)

and the variable terms on the right side of the inequality.
Answers
Answer:
so subtract -2v to the left side add 5 to the right side so your left with
v = 15
Answer:
15 = v
Step-by-step explanation:
First start by grouping like terms,
=> - 5 - 10 = 2v - 3v
evaluate the LHS and RHS
=> - 15 = - v
Divide through by the coefficient of v, which in this case is - 1
=>

Therefore, 15 = v

A coat is priced $50. If the sales tax is 7% of the price, how much is the sales tax? What is the total cost including sales tax?
Answers
Answer:
The sales tax is $3.5
The total cost is $53.5
Step-by-step explanation:
To find the sales tax, you have to find the 7 percent of 50 dollars. In decimal form, 7% is 0.07. So you just have to multiply 0.07 to 50.
50 x 0.07 = 3.5
That's why $3.5 is the sales tax.
In order to get the total cost including sales tax. You just have to add $50 to the sales tax which is $3.5.
$50 + $3.5 = $53.5

identify the steeper line y = 3x + 4 or y = 6x + 11
Answers
Answer:
y=6x+11
Step-by-step explanation:
The slope of y=3x+4 is 3 and the slope of y=6x+11 is 6.
Hope this helps :)
y = 3x + 4 is the steeper line with the slope 3
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given two lines are y = 3x + 4 and y = 6x + 11
In the given line y = 3x + 4
The slope of the line is 3
In the given line y = 6x + 11
The slope of the line is 6
Among the two lines the line y = 3x + 4 has less slope. So the the steeper line y = 3x + 4
Hence, y = 3x + 4 is the steeper line with the slope 3

A box has a volume of 1008 cubic inches. Your friend told you that he found the polynomial that represents the volume of the box: 4x³-28x² +144x. If x is the height of the box how tall is the box?
Answers
Answer:
7 inches tall
Step-by-step explanation:
A graphing calculator quickly finds the solution to the cubic equation. It is convenient to define ...
f(x) = 4x^3 -28x^2 +144x -1008
so f(x) = 0 gives the value of x that is of interest. That value is x=7.
The box is 7 inches tall.
_____
The equation f(x) = 0 can be divided by 4 to give ...
x^3 -7x^2 +36x -252 = 0
This can be factored by grouping:
(x^3 -7x^2) +(36x -252) = 0
x^2(x -7) +36(x -7) = 0
(x -7)(x^2 +36) = 0
The only real root is x = 7, which makes a factor zero.
_____
Additional comment
For finding solutions to cubic and higher-degree polynomials, I find a graphing calculator to be an extremely helpful tool. Desmos provides an online calculator and apps for various platforms. It may take a little while to learn how to use it effectively, but it can save immense amounts of time and frustration. Of course, your handheld graphing calculator can be just as useful.

How to find missing angle of a right triangle given 2 sides
Answers
Answer:
As a rule of thumb, if you know only the two shorter side, their ratio is the tangent of the angle opposed to the side you use as a numerator.
If you know one side and the hypotenuse, the ratio side/hypotenuse is either the sine of the opposite angle, or the cosine of the adjacent angle.
