9 1/3 to a fraction show me

Answer:

Let us consider that ,

The worker can complete the work in x hours .

So, he can complete 1/x part of work in 1 hour.

Now, The workers does 2/3 of what he does. So they do 2/3(1/x) part of work in 1 hour . 2/3x work in 1 hour .

Consider them all working together,

So work done in one hour, = 1/x + 2/3x + 2/3x = 3 + 4 / 3x = 7/3x .

So, They taken 1 hour to complete 7/3th part of work. So, In 3x/7 hours , They all can complete the work.

Ratio of the time taken by all instead of only one = 3x/7 : x = 3/7 .

So ,The required option is 3/7

Answer:

The answer is 4,380

Step-by-step explanation:

I took the test

The final altitude of the hot air balloon is 4380 feet.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its value and then multiply it by 100.percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.

As per the given data:

Initial altitude of the balloon = 4000 feet

First altitude reduces by 3%.

Second time it increases by 500 feet.

Decrease in altitude for first time = 4000 × (3/100) = 120 feet.

Altitude after first time = 4000 - 120 = 3880 feet

Altitude after second time = 3880 + 500 = 4380 feet

final altitude of the hot air balloon = 4380 feet

Hence, the final altitude of the hot air balloon is 4380 feet.

Answer:

The Energizer Pack

Step-by-step explanation:

To figure this out I would divide to find the price per thing then compare.

So 2.97 divided by 4 is 0.7425. We'll round that later if we have to.

12. 39 divided by 10 is 1.239

Now we compare. Which is cheaper, or less - 0.74 or 1.24?

0.74 is less, so that means the Energizer pack is the better buy since it's cheaper.

Please mark brainliest if possible and i hope you get a good grade on youe homework! :)

Answer:

Step-by-step explanation:

We know that:

Solution:

Looking at the cost per battery pack, we can say that 4 packs of Energizer is a better buy because its cost per pack is lower than the cost of 10 packs of Duracell batteries.

From the information given, the differential equation will be di/dt = (E - Ri) / L.

From the information given, we can set up the differential equation as:

-E(t) = Ldi(t)/Dr + Ti(t) = 0.

Here, i(t) = I

E(t) = E

Therefore, this will be:

= -E + Ldi/dt + Ri = 0

We'll now solve for di/dt

Ldi/dt = E - Ri

di/dt = (E - Ri) / L

the sum o the integers between 1 and 640 is 204,120

Step-by-step explanation:

add all the numbers from 1 to 640 to give 204, 120 like 1+2+3+4+5.....

[tex]tan(x)=2.5\implies \measuredangle x=tan^{-1}(2.5)\implies \measuredangle x\approx \begin{cases} \stackrel{I~Quadrant}{68.2^o}\\\\ \stackrel{III~Quadrant}{248.2^o} \end{cases}[/tex]

Make sure your calculator is in Degree mode, Check the picture below on the left side.

well, the tangent recall is sine/cosine, or namely y/x, for that fraction if either of them is negative, the whole fraction is negative, if both are either positive or negative, the fraction is positive.

given such, on the 1st quadrant and 3rd quadrant that fraction y/x is positive because on the 1st quadrant both are positive and on the 3rd quadrant both are negative, yielding the fraction, namely tangent, positive.

[tex]cos(x)=-0.7\implies \measuredangle x=cos^{-1}(-0.7)\implies \measuredangle x\approx \begin{cases} \stackrel{II~Quadrant}{134.43^o}\\\\ \stackrel{III~Quadrant}{225.57^o} \end{cases}[/tex]

now, check the picture below on the right side, cosine or namely "x", is negative on the 2nd and 3rd quadrants only, the first angle you'd get from your calculator will be 134.43°, now, this one is on the 2nd quadrant, so it has a margin from 180° of 180 - 134.43 = 45.57, that means the angle of reference is 45.57° in red in the picture.

to get the 2nd angle on the 3rd quadrant, we add to 180° the reference angle, so 180 + 45.57 = 225.57°.

Ratio is used to show the quantitative relation between two amounts. Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

The ratio is 1:3, hence for 24 buckets:

Number of cement = (1 / (1 + 3)) * 24 = 6 buckets
