What is division?Division is the process of splitting a number or an amount into equal parts.
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
she pays $10.50 to rent the bike for 14 minutes,
i.e. the average price per minute is,
$10.50 /14
=$0.75
Hence, $0.75 is the average price per minute.

[tex]5^{-2}[/tex] × [tex]\sqrt[3]{8}[/tex]
Give your answer in decimal
Answer:
0.08
Step-by-step explanation:
∛8 = 2 as 2*2*2 = 8
[tex]5^{-2}[/tex] = [tex]\frac{1}{5^{2} }[/tex] = [tex]\frac{1}{25}[/tex]
[tex]\frac{1}{25}[/tex] * 2 = [tex]\frac{2}{25}[/tex] = 0.08

BC 136m, AB 89m
BC 89m. AB 136m
BC 105m, AB 162m
BC 162m, AB 106m
Answer:
BC 136m, AB 89m
Step-by-step explanation:
Find the diagram attached
According to sin rule;
a/sinA = b/sinB = c/sinC
From the diagram;
b = 120m
<B = 60degrees
<C = 40degrees
From the sine formula
b/sinB = c/sinC
120/sin60 = c/sin40
csin60 = 120sin40
c = 120sin40/sin60
c = 120(0.6428)/0.8660
c = 77.1345/0.8660
c = 89.06
c = AB = 89m
Get BC;
According to the sine rule
a/sinA = b/sinB
a/sin(180-100) = 120/sin60
a/sin80 = 120/sin60
asin60 = 120sin80
a = 120sin80/sin60
a = 120(0.9848)/0.8660
a = 118.177/0.8550
a = 136.46
Hence a = BC = 136m

Answer:
the mean is 9
Step-by-step explanation:
add all the numbers then divide by 6
Answer:
The mean is 9.
Step-by-step explanation:
The mean of a data set is all of the numbers added together, divided by how many numbers are present.
For instance, 10+10+8+9+7+10 = 54.
Since there are 6 numbers in this data set, you divide 54 by 6 and get 9.
Therefore, the mean of this data set is 9.

Answer:
390%
Step-by-step explanation:
We are given the mixed fraction:
3 9/10
Convert to improper fraction
39/10
Converting this to Percentage :
39/10 × 100
= 3900/10
= 390%
Therefore: 3 9/10 as a percentage = 390%

Instructions
Search your home for a rectangular prism. Some examples are a cereal box, a CD case, or a coffee table. Measure your prism using appropriate units, such as inches, centimeters, or feet. (you can aslo make something up- as long as its an object that you can find in a house)
Complete ALL OF THESE. Show ALL work for calculations.
List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Describe the shape of the cross section when the box is cut parallel to the base.
What is the surface area of the box?
What is the surface area of the box if it is scaled up by a factor of 10?
What is the volume of the box?
What is the volume of the box if it is scaled down by a factor of 1/10
Answer:
I chose a box of cereal-------> rectangular prism
see the attached figure
Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Length: 20 cm
Width: 8 cm
Height: 32 cm
Part 2).
Describe the shape of the cross-section when the box is cut parallel to the base
the shape of the cross-section would be a rectangle of dimensions
20 cm x 8 cm
Part 3)
What is the surface area of the box?
surface area=2*area of the base+perimeter of the base*height
area of the base=20*8=160 cm²
perimeter of the base=2*[20+8]-----> 56 cm
height=32 cm
surface area=2*160+56*32------> 2,112 cm²
the answer part 3) is
2,112 cm²
Part 4)
What is the surface area of the box if it is scaled up by a factor of 10?
we know that
surface area of the larger box=[scale factor]²*surface area original box
scale factor=10
surface area original box=2,112 cm²
so
surface area of the larger box=10²*2,112-----> 211,200 cm²
the answer part 4) is
211,200 cm²
Part 5)
What is the volume of the box?
volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³
the answer Part 5) is
5,120 cm³
Part 6)
What is the volume of the box if it is scaled down by a factor of 1/10
we know that
volume of the smaller box=[scale factor]³*volume original box
scale factor=1/10
volume original box=5,120 cm³
so
volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³
the answer part 6) is
5.12 cm³

Answer:
75%
Step-by-step explanation:
You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Given the following
Total cards = 4 (6,7,8,9)
If the card is not 9, the required card will be (6,7,8)
Number of cards that are not 9 is 3
Probability = expected/total
Pr(not 9) = 3/4
express as percent
Pr(not 9) = 3/4×100
Pr(not 9) = 75%
Answer:
50%
Step-by-step explanation:
There are 4 cards, numbered 6, 7, 8, and 9. The numbers greater than 7 are 8 and 9. There are 2 numbers greater than 7.
