Find the area of the semicircle. Round your answer to the nearest hundredth.

Answer:

Equation is Y=mx+c (that's how I know it, it may differ)

Step-by-step explanation:

First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x

6-1 /-2-3 = 5/-5

= -1

So now u gotta find c, C= Y-mx

And u have got two brackets, which have an x and y, and u now have m.

Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2

So C =4

The equation now is : Y = - 1x + 4

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.

THE A N S QW ER

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

Answer:

slope = - [tex]\frac{15}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 8 ) and (x₂, y₂ ) = (7, - 7 )

m = [tex]\frac{-7-8}{7-3}[/tex] = [tex]\frac{-15}{4}[/tex] = - [tex]\frac{15}{4}[/tex]

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:

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

6 buckets of cements is needed to be mixed with sand to produce 24 buckets.

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

6 buckets of cements is needed to be mixed with sand to produce 24 buckets.
