Evaluate each expression.
Answer:
125/343
Step-by-step explanation:
This question asks for us to evaluate: (5/7)³
When a number has an exponent, the number gets multiplied by itself according to the amount of the exponent.(5/7)³
- 5/7 x 5/7 x 5/7
= 25/49 x 5/7
= 125/343

8(3v+3w-2)
Answer:
24v + 24w - 16Step-by-step explanation:
Given,
8(3v+3w-2)
(By distributive property)
= 8 × 3v + 8 × 3w - 8 × 2
= 24v + 24w - 16 (Ans)
Answer:
24v + 24w - 16
Step-by-step explanation:
Given
8(3v + 3w - 2) ← multiply each term in the parenthesis by 8
= 24v + 24w - 16

what is the distance between points (4,0) and (-2,-3)
Hi! I'm happy to help!
To solve this equation, we need to find how much distance is between the y coordinates, how much distance is between the x coordinates, and then use the Pythagorean Theorem.
Let's start with finding the distance between the x coordinates. The first x coordinate is 4, and the second is -2. This means that the distance in x is 6.
Next, we need to find how much distance is between the y coordinates. The first y point is at the y coordinate 0, and the second is at the y coordinate -3. This means that the distance in y is 3.
Now we use the Pythagorean Theorem, which says that a²+b²=c²
A and b refer legs of a right triangle, and c refers to the hypotenuse (longest side) of the right triangle. Imagine the two points on a line, the direct distance is the c, and the y and x movements alone are a and b.
Let's say x is a, and y is b. Let's insert our values:
6²+3²=c²
36+9=c²
45=c²
To find c, we need to find the square root of 45
√45
6.708203...
Rounds to about 6.7 in tenths.
So, the distance between those two points is about 6.7.

On a certain trip, a traveler is driving at a constant rate of 85 km/hour. At that rate, the number of minutes needed to complete the last 43 kilometers of the trip is between
a. 20 and 25
b. 25 and 30
c. 30 and 35
d. 35 and 40
e. 40 and 45
Answer:
30 and 35
Step-by-step explanation:
Distance covered of 85km=1hour=60minutes
Distance covered of 1km=60minutes/85km
Distance covered of 43km=60mins/85km × 43mins
= 30.35mins

What is the value of U. 51degrees, 79degrees and u.
Hi ;-)
[tex]u+51^o=79^o\\\\u=79^o-51^o\\\\\huge\boxed{u=28^o}[/tex]
The required equation is,
→ 51° + U = 79°
Now we should,
find the required value of U.
→ 51° + U = 79°
→ U = 79° - 51°
→ [U = 28°]
Let's check whether the required value of U is correct or incorrect,
→ 51° + U = 79°
→ 51° + 28° = 79°
→ 79° = 79°
→ LHS = RHS
Hence, 28° is the required value of U.

The number sets that apply to -4/5 is the fractions.
What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now the given number is,
-4/5
-4/5 is a fraction. A fraction has two components numerator and denominator. This can positive or negative. Other example of fractions include 1/2,3/2,-5/2,-1/3.
The numbers who are not fractions are 0, 3, 6, 7.7.

Step-by-step explanation:
We can calculate the volume V of a rectangular prism using V = lwh, where l is the length, w is the width, and h is the height of the
prism. Suppose that a prism has a volume of 200 cm and l = 2w.
a. Select all of the equations that rewrite the volume formula by making substitutions for V and l.
200 = 2w²h
200 = 4wh
V = 22
2w xwxh = 200
Answer:
Step-by-step explanation:
200=2w²h
The equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200
We have a prism and the formula to calculate its volume is given.
We have to select all of the equations that rewrite the volume formula by making substitutions for V = 200 cubic centimeter and L = 2w.
What is Prism ?A Prism is a three-dimensional shape, which consists of two identical polygons, which do not lie in the same axis.
According to the question, we have -
Volume of Prism = 200 cubic centimeter
L = 2w
The formula to calculate the volume of prism equals to -
V = Lwh
Substituting values, we get -
200 = 2[tex]w^{2}[/tex]h
or
2w x w x h = 200
Hence, the equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200

you have the total perimeter : 84.6
so now you just have to withdraw every side you have to the total , and the missing measure will be the result.

4. Explain the difference between (-5)2 anc
-52.
Answer: The answer is super easy bc it is only a small difference. The outcome of (-5)^2 will be 25 meanwhile -5^2 will have an outcome of -25
Answer:
(-5)² = 25 -5² = -25
Step-by-step explanation:
When we have (-5)², then -5 gets multiplied to itself. When there are two negative numbers, the answer is always positive. ex. (-5 x - 5 = 25)
(-5)² = 25
-5 x 5 = -25
-5² = -25
