Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.

Given:
The expression is
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=[/tex]
To find:
The simplified form of the expression.
Solution:
We have,
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=[/tex]
The expression [tex]\sqrt[3]{48}[/tex] can be written as
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}[/tex]
[tex]\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}[/tex] [tex][\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}][/tex]
[tex]\sqrt[3]{48}=2\cdot \sqrt[3]{6}[/tex]
[tex]\sqrt[3]{48}=2\sqrt[3]{6}[/tex]
Therefore, [tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}=2\sqrt[3]{6}[/tex].

Find the length indicated please!!
Find the length of CA to the nearest tenth of a foot
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{CA}[/tex] = [tex]\frac{2.6}{CA}[/tex] ( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA = [tex]\frac{2.6}{tan40}[/tex] ≈ 3.1 ft ( to the nearest tenth )

Find the shortest length of wood that can be cut into equal lengths of 3m. 8

Answer:
24
Step-by-step explanation:
Find LCM of 3 8 and 12
(calculation attached)
lcm = 3 x 2 x 2 x 2 = 24
i hope im right!
The shortest length of the wood will be 24 meters.
The Least Common Multiple (LCM) refers to the common multiple that is the least (smallest) among all possible multiples for both numbers. Calculating this least common multiple for numbers is made easier by the LCM formula.
Given that the length of the wood is 3m, 8m, and 12 m. The shortest length will be calculated by taking the least common factor of the given lengths 3m, 8m, and 12 m.
The least common factor is calculated as:-
3 = 3 x 1
8 = 2 x 2 x 2
12 = 2 x 2 x 3
LCM = 3 x 2 x 2 x 2 = 24
Hence, the shortest length of the wood will be 24 meters.

Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year's value. At this rate, what can Dan expect the approximate value of the computer to be after 8 years?
Answer:
$90
Step-by-step explanation:
Given data
Price= $900
Rate= 25%
Time= 8 years
Let us apply the compounding formula
A= P(1-r)^t >>>>note that the negative sign is because of the depreciation
substitute
A= 900(1-0.25)^8
A= 900(0.75)^8
A= 900*0.100
A= $90
Hence the value of the car after 8 years will be $90

Given the series 2+ 6 + 18+
*
use an appropriate formula to find S12.
Please put full solution.
Answer: Samsung Galaxy S12
Answer:
S₁₂ = 531440
Step-by-step explanation:
There is a common ratio between consecutive terms, that is
r = 6 ÷ 2 = 18 ÷ 6 = 3
This indicates the sequence is geometric with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( r ≠ 1 )
where a is the first term and r the common ratio
Here a = 2 and r = 3 , then
S₁₂ = [tex]\frac{2(3^{12}-1) }{3-1}[/tex]
= [tex]\frac{2(531441-1)}{2}[/tex]
= 531441 - 1
= 531440

A cylinder has a base with a radius of 7 cm and a volume of 615.44 cm3. Use 3.14 for π . Write and solve an equation to find the height of the cylinder.
Answer:
The height is 4 cm
Step-by-step explanation:
V = (pie) x radius² x height
615.44 cm³ = (3.14) x 7² x h
h = 615.44 cm³/(3.14 x 49)
h = 615.44 cm³/153.86
h = 4 cm²
