Find the value of x.
69°
(2x-1)°

Answers

Answer:

x = 11

Step-by-step explanation:

69° + (2x - 1)° = 90° (complementary angles)

69 + 2x + 1 = 90

Add like terms

69 - 1 + 2x = 90

68 + 2x = 90

Subtract 68 from each side

68 + 2x - 68 = 90 - 68

2x = 22

Divide both sides by 2

2x/2 = 22/2

x = 11

Behind Lin’s house there is a kiddie pool that holds 180 or 680 units of water, depending on which unit you are using to measure. Which measurement is in gallons, and which is in liters?

180? 680?

Answers

Answer:

180 gallons of water; 680 liters of water

Step-by-step explanation:

theres about 3.78 liters in a gallon, and when you multiply that by 180 you get 680.4! gallons are bigger then liters, so they'd be less of them.

Please help 20 points !

Answers

Answer:

C

Step-by-step explanation:

We are given the function:

[tex]f(x)=y=5x^3-6[/tex]

And we want to find its inverse.

In order to find the inverse of a function, we take the following steps:

1) Switch the independent variable x with the dependent variable y.

2) Solve for the dependent variable y.

We have:

[tex]y=5x^3-6[/tex]

Switching the two variables:

[tex]x=5y^3-6[/tex]

Solve for y. We will add 6 to both sides:

[tex]x+6=5y^3[/tex]

Dividing both sides by 5:

[tex]\displaystyle y^3=\frac{x+6}{5}[/tex]

And taking the cube root of both sides:

[tex]\displaystyle y=\sqrt[3]{\frac{x+6}{5}}[/tex]

Thus:

[tex]\displaystyle f^{-1}(x)=\sqrt[3]{\frac{x+6}{5}}[/tex]

Our answer is C.

5. What is another way to write 3√12?

Answers

Answer:

ANSWER FOR THIS IS:6√3

ExplanationThe square root of 12 is the same as the square root of (4 x 3), which is the same as the square root of 4 times the square root of 3. The square root of 4 is 2. So 3 times the square root of 12 is the same as 3 times 2 times the square root of 3.

Another way to write the expression 3√12 is 6√3.

What is another way to write 3√12?

Given the expression 3√12.

First, we rewrite 12 as 2²×3

3√12 = 3√( 2² × 3 )

Next, we pull terms out from under the radical.

3√12 = 3√( 2² × 3 ) = 3 × (2√ 3 )

Next, we multiply 3 and 2

3 × (2√ 3 ) = 6√3

Therefore, another way to write the expression 3√12 is 6√3.

Given the labeled diagram at the left. Find X.

Answers

Answer:

x = 55°

Step-by-step explanation:

Measure of central angle is equal to the measure of the corresponding minor arc

Therefore, m(central angle) = 70°

Since, radii of same circle are equal

Therefore, measure of the angles opposite to them are also equal.

So, by interior angle sum postulate of a triangle:

x + x + 70° = 180°

2x = 180° - 70°

2x = 110°

x = 110°/2

x = 55°

Juan and his family fly from London to Rio de Janeiro.

The local time in Rio de Janeiro is 5 hours behind the local time in London.
Work out the time in Rio de Janeiro when the plane arrives.​

Answers

Answer:

The time in Rio de Janeiro when the plane arrives is 17:00.

Step-by-step explanation:

Since Juan and his family fly from London to Rio de Janeiro, the plane departs at 10:20 and arrives in Rio de Janeiro 11 hours 40 minutes later, and the local time in Rio de Janeiro is 5 hours behind the local time in London To work out the time in Rio de Janeiro when the plane arrives, the following calculation must be performed:

(10:20 + 11:40) - 05:00 = X

22:00 - 05: 00 = X

17:00 = X

Thus, the time in Rio de Janeiro when the plane arrives is 17:00.

Answers

Using root/exponent properties, the result of the product is d.

A radical integer can be written in exponential form, according to the following relation:

[tex]\sqrt[b]{a^c} = a^{\frac{c}{b}}[/tex]

Hence:

[tex]\sqrt[3]{d} = d^{\frac{1}{3}}[/tex]

Then, applying the multiplication, and the power of power property, the expression can be represented as:

[tex](d^{\frac{1}{3}})^3 = d^{\frac{3}{3}} = d^1 = d[/tex]

Thus, the result of the product is d.

The two smaller angles add up to the measure of the total angle, so

(like a lot of geometry) it is really just an Algebra 1 problem with a nice picture to go with it --->  (5x + 13°) + (3x + 33°) = 70°

x = 3°

There is no actual question shown, but I imagine you want one or more of the following:

x = 3°

∠ABC = 3(3°) + 33° = 9°+ 33° = 42°

∠CBD = 5(3°) + 13° = 15° + 13° = 28°

A flower is constructed by 44 workers in 99 days.if 121 workers are employed to do the job.how many days will it take to complete the construction.​

Answers

9514 1404 393

Answer:

  36

Step-by-step explanation:

We assume that time is inversely proportional to the number of workers. So increasing the number of workers by a factor of 121/99 = 11/9 will decrease the number of days by a factor of 9/11.

  (9/11)(44 days) = 36 days

It will take 36 days to complete the construction with 121 workers.
