Step-by-step explanation:
Solve for x: 2x^5/3-22=464 a) x = 28 b) x = 27 c) x = ±27 d) x = ±28
Answer:
x = 27Step-by-step explanation:
Given the expression [tex]{2x^{\frac{5}{3} }-22 = 464[/tex], we are to find the value of x in the expression. This is as shown below;
[tex]{2x^{\frac{5}{3} }-22 = 464[/tex]
add 22 to both sides
[tex]{2x^{\frac{5}{3} }-22 = 464+22\\\\[/tex]
[tex]{2x^{5/3} =486[/tex]
divide both sides by 2
[tex]\frac{2x^{5/3}}{2} =\frac{486}{2}\\ x^{5/3} = 243[/tex]
raise both sides to the power of 3/5
[tex](x^{5/3})^{3/5} = (243)^{3/5}\\x = (\sqrt[5]{243}) ^3\\x = 3^3\\x = 27[/tex]
Hence the value of x is 27
How do you do letter d? I keep getting the wrong answer
Answer:
18
Step-by-step explanation:
The integral is the area between f(x) and the x-axis. Remember that area below the x-axis is negative.
The area between x=0 and x=6 is a trapezoid.
The area between x=6 and x=9 is a rectangle.
The area between x=9 and x=15 is a triangle.
The area between x=15 and x=21 is a triangle.
The area between x=21 and x=27 is a trapezoid.
A = ½ (3+9) (6) + (3)(9) + ½ (6)(9) + ½ (6)(-9) + ½ (-9+-6) (6)
A = 36 + 27 + 27 − 27 − 45
A = 18
solve the inequality 9(x/3+1) > 6
Step-by-step explanation:
On solving the inequality, we get the solution inequality as -
x > -1.
What is a Inequality? What is equation modelling? What is a mathematical equation and expression?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.
Given is the inequality -
9(x/3 + 1) > 6
The given inequality is -
9(x/3 + 1) > 6
(x/3 + 1) > (6/9)
(x/3 + 1) > 2/3
x/3 + 1 - 1 > 2/3 - 1
x/3 > (2 - 3)/3
x/3 > -1/3
x > -1
Therefore, on solving the inequality, we get the solution inequality as -
x > -1.

A Fahrenheit thermometer shows that the temperature is 15 degrees below zero. Enter the integer that represents the temperature in degrees Fahrenheit.
Answer:
The integer that represents 15 degrees below 0 is -15°F.
Step-by-step explanation:
This is because the phrase "15 degrees below 0" is obviously not an integer meaning that the corresponding integer to this phrase would be -15.
The thermometer shows - 15°F the temperature is 15 degrees below zero.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit.
Given, A Fahrenheit thermometer shows that the temperature is 15 degrees below zero.
So, If we assume the thermometer as a number line it is 15 units left to the origin.
∴ (0 - 15)°F.
= - 15°F.

How do the surface areas of similar prisms compare when dimensions are doubled?
O A The surface area of the larger prism is 2 times the surface area of the smaller prism.
OB. The surface area of the larger prism is 4 times the surface area of the smaller prism.
OC. The surface area of the larger prism is 8 times the surface area of the smaller prism.
Answer:
The surface area of the larger prism is 4 times the surface area of the smaller one.
(which agrees with answer B in your list)
Step-by-step explanation:
Notice that the lateral surface area of prisms always consists of parallelograms, whose areas are given by the product base times height. = B x H
Therefore if the dimensions of the prism double, then the base and height of the parallelograms will double as well, making such individual ares of the lateral faces go from:
B x H to --> 2 B x 2 H = 4 (B x H)
that is 4 times the original lateral face's area.
with the faces for the top and bottom bases of the prism, something similar happens, so we conclude that the surface area of the larger prism is 4 times the surface area of the smaller one.

1200-5(3x+30)=600 show the steps to solve this problem
Answer:
x=+30
Step-by-step explanation:
1200-5(3x+30)=600
We move all terms to the left:
1200-5(3x+30)-(600)=0
We add all the numbers together, and all the variables
-5(3x+30)+600=0
We multiply parentheses
-15x-150+600=0
We add all the numbers together, and all the variables
-15x+450=0
We move all terms containing x to the left, all other terms to the right
-15x=-450
x=-450/-15
x=+30
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 30}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{1200 - 5(3x + 30) = 600}[/tex]
Distribute 5 through the parentheses
[tex] \dashrightarrow{ \sf{1200 - 15x - 150 = 600}}[/tex]
Subtract the numbers: 150 from 1200
[tex] \dashrightarrow{ \sf{ - 15x + 1050 = 600}}[/tex]
Move 1050 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{ - 15x = 600 - 1050}}[/tex]
Subtract 1050 from 600
[tex] \dashrightarrow{ \sf{ - 15x = 450}}[/tex]
Divide both sides of the equation by -15
[tex] \dashrightarrow{ \sf{ \frac{ - 15x}{ - 15} = \frac{ - 450}{ - 15} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{x = 30}}[/tex]
Hope I helped!

If the distance marked on centimeter scale is from 2.5 to 4.5,
then the line segment is how many cm long?
Answer:
2.0cm longStep-by-step explanation:
If the distance marked on a centimeter scale is from 2.5 to 4.5, then the final destination is 4.5cm and the initial point = 2.5.
Distance between the two points will give us the length of the line segment.
Distance between the two points = final point - initial point
Distance between the two points = 4.5 - 2.5
Distance between the two points = 2.0 cm
Hence the line segment is 2.0cm long
