The value of y varies directly with x. When y = 3.5, x = 2.
What is the value of y when x is 16?

Answers

Answer 1
in order to do this problem, you have to divide 16 by 2 to see how many times x was multiplied. you would find that x was multiplied 8 times, so in order to find y, you would multiply 3.5 eight times.

y = 28 when x = 16

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].

Jim was thinking of a number. Jim divides by 8, then adds 9 to get an answer of 6. What was the original number?

Answers

To find the answer, you must go back and do the opposite. You know the final result was 6. Now, you must do the opposite of what it said. It said it added 9, so you have to minus nine. (6-9=-3) Then, it said it divided the number by 8, so you have to multiply by 8. (-3x8=-24) The origins number was -24.

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

Answers

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.


What is the least common factor?

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.

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?

Answers

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.

Find the length of CA to the nearest tenth of a foot

Answers

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 )

Answer:

Robbie's glider

Step-by-step explanation:

Robbie reaches the greater maximum altitude in the first 6 seconds after launch option (C) Robbie's glider is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

Melissa and Robbie are flying remote control gliders.

The altitude of Melissa's glider, h(s), in feet, is modeled by this function:

m(s) = 0.4(s³ - 11s² + 31s - 1)

Plug s = 6 seconds in the function m(s)

m(6) = 0.4(6³ - 11(6)² + 31(6) - 1)

m(6) = 0.4(216 - 396 + 186 - 1)

m(6) = 0.4(5)

m(6) = 2 feet

From the graph of Robbie:

At s = 6 seconds

Altitude = 13 feet (approximately)

Thus, Robbie reaches the greater maximum altitude in the first 6 seconds after launch option (C) Robbie's glider is correct.
