The expression for the total number of blocks is b³
This question seems to be incomplete. Here is the complete question :
A toy manufacturer produces a set of blocks that can be used by children to build play structures. The product packaging team is analyzing different arrangements for packaging their blocks. One idea they have is to arrange the blocks in the shape of a cube, with b blocks along one edge.
Write an expression representing the total number of blocks packaged in a cube measuring b blocks on one edge.
A cube is a 3-dimensional object that has six faces.
Characteristics of a cube
It has six faces It has twelve edges It has eight vertices Intersecting edges are perpendicularVolume of a cube = a³
Where a = length of a side
The expression that would be given is the volume of a cube. Since the length of the edge is b, the expression would be b³

Find the value of x.
Answer:
Step-by-step explanation:
Those two angles are equal. They are corresponding angles. In two parallel lines crossed by a transversal. 8 angles are produced. 4 have one value and the other 4 are supplementary to the first four.
These 2 are part of the first group of 4.
So 12x - 8 = 104
12x - 8 + 8 = 104 + 8
12x = 112
x = 9 1/3

Convert 19.3 picometers per squared kiloseconds (pm/ks^2) into megameter per squared nanoseconds (Mn/ns^2).
Unit conversion involves the conversion of a metric unit to another unit of the same quantity.
[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]
Let:
[tex]x = 19.3 pm/ks^2[/tex]
Multiply by [tex]10^{-17[/tex] to convert megameter per squared kiloseconds
[tex]x = 19.3 \times 10^{-17} Mn/ks^2[/tex]
Divide by [tex]10^{24[/tex] to convert to megameter per squared nanoseconds
[tex]x = \frac{19.3 \times 10^{-17}}{10^{24}} Mn/ns^2[/tex]
Apply law of indices:
[tex]x = 19.3 \times 10^{-17-24} Mn/ns^2[/tex]
[tex]x = 19.3 \times 10^{-41} Mn/ns^2[/tex]
Hence:
[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]

15 people fit comfortably in a 6 feet by 6 feet area. Use this value to estimate the size o a crowd that is 30 feet deep on both sides of the street along a 2-mile section of a parade route. (Hint: 1mile= 5,280ft)
158,400 people will fit into an area with a dimension of 30feets by 2 miles.
The area of the street can be calculated thus :
Area = Length × width
Converting the width to feets :
1 mile = 5280 feets
2 miles = x
Cross multiply :
x = 5280 × 2 = 10560 feets
Area = 10560 ft × 30ft = 316800 ft²
Since 15 people fit into an area with dimension which is 6 ft by 6ft
Area = 6 × 6 = 36 ft²
Let x = number of people
15 people = 36 ft²
x people = 316800 ft²
Cross multiply :
x = (316800 × 15) / 36
x = 158,400 people
Hence 158,400 people will fit in.

Line segment JM has endpoints with coordinates 0 and 25 on a number line. Points K and L are on segment JM. K has a coordinate of 5 and point L has a coordinate of 12. Find the probability that a point on JM is placed first on JL and a second point is not placed on KL.
Answer:
D. 216/625Step-by-step explanation:
The length of the segment JM is 25 units.The segment JL is between 0 and 12, so is 12 units.The segment KL is between 5 and 12, so is 7 units.The probabilities for each point:
P(point on JL) = 12/25P(point not on KL) = 1 - 7/25 = 18/25Required probability:

A truck can be rented from Company A for $120 a day plus $0.20 per mile. Company B charges $60 a day plus $0.40 per mile to rent the same truck. Find the number of miles in a day at which the rentals cost for company A and company B are the same.
please help..
Answer:
12 miles in a day.
Step-by-step explanation:
Variable x = number of miles
Company A: 120 + 0.20x
Company B: 60 + 0.40x
Set up an equation:
120 + 0.20x = 60 + 0.40x
60 + 0.20x = 0.40x
60 = 0.20x
12 = x

For her phone, Halima pays a monthly fee of 18 AED and she pays an additional 5 fils per minute of use. The least she has been charged in a month is 71.90 AED. What is the minimum number of minutes she has used on her phone in a month?
Answer:
1078 minutes
Step-by-step explanation:
18 + 0.05x = 71.90
0.05x = 71.90 - 18
0.05x = 53.9
x = 53.9/0.05
x = 1078 minutes
The minimum number of minutes is 1078 minutes.
To find the minimum number of minutes she has used on her phone in a month.
What is arithmetic?The branch of mathematics dealing with the properties and manipulation of numbers.
Given that :
Halima pays a monthly fee of 18 AED and she pays an additional 5 files per minute of use. The least she has been charged in a month is 71.90 AED.
so, that
18 + 0.05x = 71.90
0.05x = 71.90 - 18
0.05x = 53.9
x = 53.9/0.05
x = 1078 minutes
So, the minimum number of minutes is 1078 minutes.
