Which equation justifies why ten to the one third power equals the cube root of ten?
Answers
Answer:
Step-by-step explanation:
AC and D are all wrong. The all add or subtract something from 3 which is not going to keep the two sides of the equation equal.
Only B is correct. To get the two sides equal, you need to multiply the powers by the same constant. B does this. The powers and the constant 1/3 * 3 are the same on both sides.
The cost of a book is $x what is the expression in terms of x for the number of these books which are bought for $40
Answers
Answer:
In x dollars,
number of book that can be bought = 1
So, In 1 dollar,
number of books that can be bought = 1/x
Hence in 40 dollars,
number of books that can be bought = 40/x
Answer:
40/x
Step-by-step explanation:
The cost of 1 book is $X.
You bought (?) books for $40.
If you want to know how many books you bought, divide the total cost of books ($40) by the cost of 1 book ($X).
Sam bought an electric iron as a price of 25 less than the original price if the original price of it is $2500 at what price did Sam buy the electric iron
Answers
Answer:
$2475 or $1875
Step-by-step explanation:
Assuming the question meant to say $25 less than the original price, it would be $2475 because $2500-$25= $2475
However, if the question meant to say that Sam bought the iron for 25% less than the original price, it would be $1875 because 2500*0.25= $625
$2500-$625= $1875

Subtract 5x from each side
x^2 + 4x-5x-9 = 5x -5x+ 3
x^2 +-x-9 = 3

B. 1/2x(2x - 1) = 36
C. 1/2x(2x - 1) = 18
D. x(2x - 1) = 18
Answers
Answer:

Step-by-step explanation:
Given:
Area of triangle = 36 m²
Length of base = 2(Height) - 1
Find:
Equation for area
Computation:
Assume;
Height = x
Area of triangle = (1/2)(b)(h)

Answer:
Perimeter of ΔPRS = 35.91 units
Step-by-step explanation:
From the figure attached,
By applying triangle sum theorem in the given triangle PRS,
m∠P + m∠R + m∠S = 180°
45° + m∠R + 60° = 180°
m∠R = 75°
By applying sine rule,
[tex]\frac{\text{sinP}}{RS}= \frac{\text{sinS}}{PR}=\frac{\text{sinR}}{PS}[/tex]
[tex]\frac{\text{sin}(45^{\circ})}{10}= \frac{\text{sin}(60^{\circ})}{PR}=\frac{\text{sin}(75^{\circ})}{PS}[/tex]
[tex]\frac{\text{sin}(45^{\circ})}{10}= \frac{\text{sin}(60^{\circ})}{PR}[/tex]
PR = 12.25 units
[tex]\frac{\text{sin}(45^{\circ})}{10}=\frac{\text{sin}(75^{\circ})}{PS}[/tex]
PS = 13.66 units
Perimeter of triangle PRS = PR + PS + RS
= 12.25 + 13.66 + 10

Triangle DEF is simliar to triangle QRS. If side QR is 1.5 times the length of side DE, and side RS has a length of 6, what is the length of side EF? Also, there is no picture for this question.
Answers
Answer:
4
Step-by-step explanation:
the scaling factor is 1.5 to go from DEF to QRS.
so,
EF × 1.5 = RS = 6
EF = 6 / 1.5 = 6/1 / 3/2 = 6×2 / 1×3 = 12/3 = 4
What is the area of a hexagon with an apothem of 24 m?
Answers
Answer:
Area of Hexagon = 1,995 m² (Approx.)
Step-by-step explanation:
Given:
Length of apothem = 24 m
Number of total sides = 6
Find:
Area of Hexagon
Computation:
Side = a[2tan(180/n)]
Side = 24[2tan(180/6)]
Side = 24[2tan(30)]
Side = 27.71 m (Approx.)
Area of Hexagon = [3√3a²]/2
Area of Hexagon = [3(1.732)(27.71)²]/2
Area of Hexagon = [3(1.732)(767.8441)]/2
Area of Hexagon = 3989.71794 / 2
Area of Hexagon = 1994.8589
Area of Hexagon = 1,995 m² (Approx.)

How many solutions does 8x=−9+7x have?
Answers
Answer:
The equation has only one solution, x = -9
Step-by-step explanation:
We want to find how many solutions the equation:
8x = -9 + 7x
has.
To find it, let's simplify the equation.
First, let's move all the terms with x to the left side, and the terms without x to the right side:
8x - 7x = -9
(8 - 7)*x = -9
1*x = -9
x = -9
So we can see that we have only one solution, x = -9

Two numbers are in the ratio 2:3 and their sum id 45 then find both number
Answers
Answer:
Step-by-step explanation:
Let the two numbers be 2x and 3x.
According to the question,
2x+3x=45
5x=45
x=45/5
x=9
so th required numbers are 18 and 27 as
2x=2*9=18
3x=3*9=27
It is given that,
→ Two numbers are in the ratio 2:3.
→ Their sum is 45.
We have to,
find the both required numbers.
Now assume numbers as,
→ 2y and 3y
As per the given information,
→ 2y + 3y = 45
First we can find the value of y,
→ 2y + 3y = 45
→ 5y = 45
→ y = 45/5
→ [y = 9]
The given ratio is,
→ 2 : 3
Let's find the value of 2y,
→ 2y --- {y = 9}
→ 2 × (9)
→ 18
Let's find the value of 3y,
→ 3y --- {y = 9}
→ 3 × (9)
→ 27
Hence, the number is 18 and 27.
which describes a greater unit rate of change of Y with respect to X the equation Y = 4.5x or the table

Answer:
The proportional relationship is same
Step-by-step explanation:
Generally, we can get the unit rate by dividing the y-value by the x-value

a cooler has 60L capacity. its internal length is 60cm and its internal width is 35cm. Determine the internal height and the internal surface area of the cooler.
Answers
Answer:
Internal height is approximately 28.5714285714286 cm
Internal surface area is roughly 9628.57142857143 square cm
Round the values however you need to
==========================================================
Step-by-step explanation:
Work Shown:
1 L = 1000 mL
1 L = 1000 cm^3
60 L = 60,000 cm^3 (multiply both sides by 60)
The cooler has volume of 60,000 cubic cm. Let V = 60000
Assuming the cooler is a rectangular prism (aka a block), then we can say
volume = length*width*height
V = L*W*H
60000 = 60*35*H
60000 = 2100H
2100H = 60000
H = 60000/2100
H = 28.5714285714286 which is approximate
And the surface area (SA) is
SA = 2*(LW + LH + WH)
SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)
SA = 9628.57142857143 which is also approximate
Units for the surface area are in square centimeters.
Chamblee High School is selling Valentine's Day gifts as a fundraising event. One long stemmed rose costs $3.00 while one long stemmed carnation costs $1.50. If 50 orders
were placed and they totaled $195, how many roses and carnations were ordered?
100 roses and 100 carnations
60 roses and 10 carnations
125 roses and 75 carnations
50 roses and 145 carnations
Answers
Answer: Choice B) 60 roses and 10 carnations
============================================================
Explanation:
r = number of rosesc = number of carnationsr and c are positive whole numbers.
r+c = total number of flowers = 50, since 50 orders are made.
The first equation to set up is r+c = 50.
This equation can be solved to get r = 50-c.
------------------
3r = cost of all the roses only, in dollars
1.5c = cost of all the carnations only, in dollars
3r+1.5c = total cost of all the flowers = 195 dollars
3r+1.5c = 195
------------------
Let's apply substitution to solve
3r+1.5c = 195
3(50-c)+1.5c = 195
150-3c+1.5c = 195
-1.5c+150 = 195
-1.5c = 195-150
-1.5c = 45
c = 45/(-1.5)
c = -30
That's not good. We shouldn't get a negative value.
It turns out that the condition r+c = 50 should be ignored. Notice how none of the answer choices listed have r+c leading to 50.
So we'll only focus on the equation 3r+1.5c = 195
-----------------
If we plugged in r = 100 and c = 100, then we get
3r+1.5c = 195
3(100)+1.5(100) = 195
300+150 = 195
450 = 195
Which is false. So we can rule out choice A
Let's repeat those steps for choice B
3r+1.5c = 195
3(60)+1.5(10) = 195
180 + 15 = 195
195 = 195
So that works out. I have a feeling your teacher meant to say "70 orders" instead of "50 orders". If so, then the equation r+c = 50 would be r+c = 70 and everything would lead to choice B as the final answer.
Choices C and D are similar to that of choice A, so they can be ruled out.
