Which of these choices show a pair of equivalent expressions? Check all that
apply.
A. (481)5 and 815/4
B. 67/2 and (VG)
C. 52/3 and (15)3
O D. 75/7 and (77)5
Given:
The pair of expressions in the options.
To find:
The pairs which show a pair of equivalent expressions.
Solution:
Property of exponent:
[tex](\sqrt[n]{x})^m=x^{\frac{m}{n}}[/tex]
In option A,
[tex](\sqrt[4]{81})^5=81^{\frac{5}{4}}[/tex]
So, option A is correct.
In option B,
[tex]6^{\frac{7}{2}}=(\sqrt[2]{6})^7[/tex]
[tex]6^{\frac{7}{2}}=(\sqrt{6})^7[/tex]
So, option B is correct.
In option C,
[tex]5^{\frac{2}{3}}=(\sqrt[3]{5})^2[/tex]
[tex]5^{\frac{2}{3}}\neq (\sqrt{5})^3[/tex]
So, option C is incorrect.
In option D,
[tex]7^{\frac{5}{7}}=(\sqrt[7]{7})^5[/tex]
[tex]7^{\frac{5}{7}}\neq (\sqrt{7})^5[/tex]
So, option D is incorrect.

x=10 y=15
x= 30 y=25
x=16 y=21
x= 32 y= 26
Answer:
the last one
Step-by-step explanation:
32+26=58
32-26=6
Answer:
The first number is 32 and the second is 26
Step-by-step explanation:
Let the two numbers be represented by x and y
1) x + y = 58
2) x - y = 6
x = 6 + y, we'll use put this in the first equation.
x + y = 58
6 + y + y = 58
6 + 2y = 58
2y = 58 - 6
2y = 52
2. 2
y=26, now let's find x, again use the first equation
x + y = 58
x + 26 = 58
x = 58 - 26
x = 32

3. The trapezoid below contains a square and two right triangles. Find the perimeter of the trapezoid.
Answer:
Perimeter of trapezoid = 25.66 cm
Step-by-step explanation:
Trapezoid ABCD contains two triangles ΔABF, ΔCDE and a square with side length 4 cm.
By applying Pythagoras theorem in ΔABF,
AB² = BF² + AF²
AB² = 4² + 3²
AB = [tex]\sqrt{16+9}[/tex]
AB = 5 cm
Similarly, By applying Pythagoras theorem in ΔCDE,
CD² = DE² + CE²
CD² = 4² + 4²
CD = [tex]\sqrt{32}[/tex]
CD =5.66 cm
Perimeter of the given trapezoid = AB + BC + CD + AD
= 5 + 4 + 5.66 + (3 + 4 + 4)
= 25.66 cm

Answer: y=1/4x-5
Step-by-step explanation:
1/4 is the slop
-5 is the y-intercept
Y=mx+b (slope-intercept form)
m=slope
b=y-intercept
y=1/4x-5
Match each shape (if possibles, and one at a time) using a translation of the original shape using a coordinate rule.
For the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The figures are given in the picture:
For the red figure: Translate 1 unit down then 3 units left.
For the yellow figure: translate 5 units down and then 2 units right
For the blue figure: Reflect the figure at the y-axis.
Thus, for the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.

Ramon paid a flat fee of $269.50 for a year's worth of vet visits for his 4 cats. He made 14 visits during the year. What was the average cost per vet visit?
Answer:
The average cost per vet visit was $19.25.
Step-by-step explanation:
From the information given, you can find the average cost per visit by dividing the total amount paid for a year's worth of vet visits by the number of visits:
269.50/14= $19.25
According to this, the answer is that the average cost per vet visit was $19.25.
KE= 0.5 .m.v2 OR PE= m.g.h Kinetic and Potential Energy Practice Problems. Solve the following problems and show your work! 1. A car has a mass of 2,000 kg and is traveling at 28 meters per second. What is the car's kinetic energy? I
Answer:
784000J or 784KJ
Step-by-step explanation:
Kinetic energy (KE) can be represented with the formula
KE = 1/2(MV²)
where
M = Mass of object (Kg) =2000kg
V = velocity or speed of object in metre per second (m/s or ms^-1) = 28m/s
therefore
KE = 1/2(mv²) becomes
KE = (1/2) X 2000 X 28 X 28
KE = 784000Joules

What is the y-intercept of y=2x-5 ?
Answer:
the y intercept is -5
Step-by-step explanation:
because the equation is y=MX+b
Answer:
The y-intercept is -5.
Step-by-step explanation:
[tex]y=2x-5[/tex]
The equation is in slope intercept form.
[tex]y = mx+b\\\\m - \text{Slope}\\\\b - \text{Y-intercept}[/tex]
Since ' -5 ' is in 'b' 's place, it is the y - intercept.

what is 2 x 1 1/2
Answer:
3
Step-by-step explanation:
2 times 1 is 2 and then multiply 1/2 by 2 and you'll get 1 then add those two numbers together and you will get 3. Note: The best way to do these types of things in multiplication is to split the numbers up among the decimal places so if you did 15 times 4 then an easy way to do it would be to split the 15 with 10 and 5 so then multiply the 10 by 4 and you get 40 now do the same to the 5 and you get 20 so now add those two numbers together and you get 60(This has nothing to do with the answer i just want to help make it easier for future problems such as this).

The cone and cylinder below have equal surface area
Answer:
Option B, False
Step-by-step explanation:
Step 1: Get the surface area formulas for both shapes
Surface Area Formula for Cone: [tex]A = \pi * r(r + \sqrt{h^{2} + r^{2}})[/tex]
Surface Area Formula for Cylinder: [tex]A = 2\pi rh+2\pi r^{2}[/tex]
Step 2: Plug in the values and solve
Cone: [tex]A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})[/tex]
Cone: [tex]A = \pi r^{2} + \pi \sqrt{10}r^{2}[/tex]
Cylinder: [tex]A = 2\pi r*r+2\pi r^{2}[/tex]
Cylinder: [tex]A=4 \pi r^{2}[/tex]
Step 3: Compare
[tex]\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}[/tex]
They are not equal, therefore the answer is False.
Answer: Option B, False
