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 )

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].

A coach buys a uniform and a basketball for each of the 12 players on the team. Each basketball costs $8. The coach spends a total of $288 for uniforms and basketballs.
Enter the cost, in dollars, of 1 uniform.
16
Step-by-step explanation:
if you multiply 12 by 8 you get 96 so then you would subtract 96 from 288 and get how much he would spend on all of them then i think you would need to divide 192 from 12 and get 16.so i think the answer is 16 correct me if im wrong

Step-by-step explanation:
they turned the negative 12 into a positive 12 in the second step. in the 3rd step they turned 4x into 20x.
4(6x+7)+3(x-4)= 4(x+4)+5(5)+50
24x+28+3x-12=4x+16+25+50

Find the shortest length of wood that can be cut into equal lengths of 3m. 8
and 12m
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.
