Answer:
D
Step-by-step explanation:
We are given
b^3
and
b=5
We are given what b is equal to, 5. Therefore, we can substitute 5 in for b
5^3
Evaluate the exponent. 5^3 is the same as multiplying 5, 3 times.
5*5*5
25*5
125
Therefore, D, 125 is the correct answer
The point-slope form of a line that has a slope of -2 and passes through point (5,-2) is shown below.
y+2=-2(x-5)
What is the equation in slope-intercept form?
O y=-2x+12
O y=-2x+8
O y=-2x-7
y=-2x-3
Answer:
y=-2x+8
Step-by-step explanation:
When consider coordinate (5, -2)
y=-2x+8
When x=5
y= -2 x 5 + 8 = -2
Therefore the answer is y=-2x+8
Lucia speed walks 3 kilometers in of an hour. At 2/3 that rate, how many meters does she speed walk per minute?
Answer:
2000 meters
Step-by-step explanation:
The first step in this problem is to find 2/3 of 3 kilometers per hour.
2/3 * 3/1 = 6/3. This can be simplified to 2 kilometers per hour.
Now, find the rate of meters per minute. To do so, multiply 2 by 1000.
2 * 1000 = 2000
Therefore, at 2/3 of Lucia's rate, she walks 2000 meters per minute.
Answer:
The answer is 75 meters per minute.
Step-by-step explanation:
Ok I been seeing people say 2000 meter which is WRONG. 1 kilo= 1,000 meters
2/3 of an hour= 40 minutes
3,000 meters/40mins= 75 meters per minute

54 X = 4,096
COMPLETE
By the sixth mailing, how many people will have participated since the start?
DONE
I need the last part
Answer:
1. Geometric sequence
2. 4,096
3. 5,460
Step-by-step explanation:
Part 1
Since the number of letters sent is multiplied by 4 for any subsequent term, the sequence is an example of a geometric sequence as it grows exponentially.
Part 2
Given a geometric sequence, the nth term is determined using the formula:
[tex]T_n=ar^{n-1},$ where r=common ratio, a=first term, n=number of terms[/tex]
In this case,
a=1 (i.e. Nyah)
r=4
Since we want to determine how many letters will be sent on the sixth mailing(i.e after Nyah), n=7
Substituting
[tex]T_6=1*4^{7-1}\\=4^6\\=4096[/tex]
Part 3
To determine how many people would have participated by the sixth mailing, we are required to find the sum of the first seven terms of the geometric sequence.
We use the sum of a geometric sequence formula
[tex]S_n=\dfrac{a(r^n-1)}{r-1} \\S_7=\dfrac{1(4^7-1)}{4-1} \\=\dfrac{16383}{3}\\\\=5461[/tex]
Therefore, excluding Nyah, 5460 people would have participated by the sixth mailing.
Answer:
1. Geometric sequence
2. 4,096
3. 5,460

List the sides in ΔEFG in order from smallest to largest. Picture includes possible solutions
The list of sides in triangle EFG in order from smallest to largest is option A) EF, EG and FG.
What is Triangle?A triangle is a polygon in two dimension which has three vertices, three edges and three angles.
There are different kinds of triangles like equilateral triangle, isosceles triangle and so on.
Given triangle EFG and the angles of the triangle is also given.
The largest side of a triangle is the side which has the largest opposite angle.
Or in other words, the side opposite to the larger angle will be having larger length.
Here the largest angle is 63°. So the side opposite to this angle which is side FG is having largest length.
Then comes the angle 62°. The side opposite to this is EG which is the side standing next to FG.
The smallest angle is 55° and the side opposite to it which is EF is having smallest side length.
So the order from smallest to largest is EF, EG, FG.
Hence the sides in order from smallest to largest is EF, EG, FG.

A customer states that she was shorted in change by receiving only 23 cents change from $3.00
dollars instead of 32 cents. How would you handle this?
Answer:
First, I would check and see if she was correct. If she wasnt, I would simply show her why she was incorrect. If I was to accidently short her, I would give her the money and move on with my day. if she refused to leave after showing her that I gave her the correct amount of money, she would probably call for the manager. I'd get the manager, explain what happened, and the annoying customer would most likely get kicked out of the store.

B. 6.2
C. 10.8
D. 12.4
Answer:
12.4 units
Step-by-step explanation:
The diameter of circle J is represented by KN. Half of KN is KJ and JN which means these represent the radius. Since JN equals 12.4 and JN is the the radius, then the radius of circle J is 12.4 units which is answer choice D.
The radius of the given circle is 6.2 unit. So option B is correct.
What is the radius?A line segment from a circle's or sphere's center to its perimeter or boundary is known as the radius in geometry. It is a crucial component of spheres and circles and is frequently abbreviated as "r". When discussing multiple radiuses at once, the plural form of radius is "radii". The diameter of a circle or sphere is the longest line segment connecting all points on the opposite side of the centre, and the radius is equal to half of the diameter in length. It can be written as d/2, where d is the circle's or sphere's diameter. Look at the illustration of a circle below that depicts the connection between radius and diameter.
Given that,
A circle,
which contains diameter KN of length 12.4 unit
and chord 10.8 unit.
The radius = ?
It is known that, the length of the radius is half of the diameter of the circle,
R = D/2
= 12.4/2
= 6.2
Therefore, the length of the radius is 6.2 unit.
