Sarah goes to dinner with two friends the total cost of dinner is $61.92 her friends pay 2/3 of the total cost exactly how much does Sarah pay

Answers

Answer:

the amount paid by Sarah is $20.64

Step-by-step explanation:

Given that

The total cost of the dinner is $61.92

And her friends pay 2 by 3

We need to find out the amount paid by Sarah

Since her friends pay 2 by 3 of the total cost

That means the remaining should be paid by Sarah i.e. 1 by 3

So, we need to multiply 1 by 3 with the total cost of the dinner i.e.

= 1 ÷3 × $61.92

= $20.64

Hence, the amount paid by Sarah is $20.64

What is the total number of unique triangles with side lengths of 6.5 centimeters, 6 centimeters, and 2.5 centimeters?\

Answers

Answer:

Total 9 unique triangles can be formed

Step-by-step explanation:

For triangles to be unique, length of one side can be arranged in 3 different ways

Let us  L1, L2 and L3 are the three sides

Now, length of 6.5 cm can be at maximum three positions i.e  L1, L2 and L3

Like wise length of 6.0 cm can be at maximum three positions i.e  L1, L2 and L3

and length of 2.5 cm can be at maximum three positions i.e  L1, L2 and L3

Hence, total ways of making unique triangles are

Answers

Answer:

166.3

Step-by-step explanation:

line that shows 8, shows that each of six sides is 8

so that's 48

to get the "apothem"

it means get a side of the triangle where the hypotenuse is 8 and the base is 4 (half of 8)

so that is square root of 48 which is like 6.928

then plug into the formula

1/2 x 6.928 x 48 which is like 166.27

Given:

The circumference of a circle is 18.

Central angle of an arc is 120 degrees.

To find:

The measure of arc length.

Solution:

The arc length of a circle is:

[tex]s=2\pi r\times \dfrac{\theta }{360^\circ}[/tex]

Where, r is the radius of the circle, [tex]\theta[/tex] is the central angle in degrees.

We know that, [tex]2\pi r[/tex] is the circumference of the circle. So, substitute [tex]2\pi r=18,\theta=120^\circ[/tex] in the above formula.

[tex]s=18\times \dfrac{120^\circ}{360^\circ}[/tex]

[tex]s=18\times \dfrac{1}{3}[/tex]

[tex]s=6[/tex]

Therefore, the length of the arc is 6 units.

Briefly explain the roles and relationships that exists amongst the producers, consumers, and decomposers in an ecosystem such as an ocean.

Answers

*They are all organisms* producers make their own food through a process called photosynthesis, decomposers get energy and nutrients to breaking down the remains of other living organisms and consumers get energy and nutrients by eating other organisms. Hope that helped:)

The roles and relationships that exist amongst the producers, consumers, and decomposers in an ecosystem is described by the food chain.

What is an ecosystem?

The meaning of ecosystem is the complex of a community of organisms and its environment functioning as an ecological unit.

Producer is an organism that produces its own food e.g. photosynthesis in plants. Also known as the base of the food-chain.

Consumer is an organism that consumes (eats) either a producer or another consumer e.g. animals will solely eat plants (herbivore), solely animals (carnivore), or a combination of both (omnivore).

Studies are showing that most animals are omnivores. Even pre-concluded herbivores or carnivores are found to eat a small variety of both plants and animals in a pinch. E.g. a deer would eat a baby bird if it found it on the ground.

Decomposers are organisms that 'eat' and break up dying/decaying material e.g. earthworms and fungi.

All of this together is the food cycle.

Karina deposito S/. 3000 en un banco en un banco a una tasa de interes simple del 2% mensual ¿Cuánto ganara en dos años

Answers

Answer:

En dos años ganará S/. 4440.

Step-by-step explanation:

Puedes encontrar la respuesta utilizando la fórmula para calcular el valor futuro:

VF=VP*(1+(i*n))

VP= valor presente= 3000

i= tasa de interés= 0.02

n= número de periodos de tiempo= 24 meses (2 años corresponden a 24 meses)

VF=3000*(1+(0.02*24))

VF=3000*(1+0.48)

VF=3000*1.48

VF=4440

De acuerdo a esto, la respuesta es que en dos años ganará S/. 4440.

The difference between two whole numbers is 99. The ratio of the two numbers is 2:5. What are the numbers?​

Answers

Let the two whole numbers be 2x and 5x

The difference between 2x and 5x is 99. So,

5x-2x=99

3x=99

x=99/3

x=33

Therefore the two numbers are

5x=5*33=165

2x=2*33=66

Answer:

28:71

Step-by-step explanation:

99/7=14.14285714 (make sure to keep that in the calculator) that equals 1 part.

Therefore,

2×14.14...=28 (round up to nearest whole number)

5×14.14..=71 (round up to nearest whole number)

what does x equal? no step by step needed.

Answers

Answer:

x = 13

Step-by-step explanation:

BD is the hypotenuse of the smaller triangle and corresponds to 2x - 7.  51 is the longer leg of triangle EFG

The ratio of the two hypotenuses is (2x - 7)/57, and the ratio of the two longer legs is (x + 4)/51.  These ratios are equal to one another.  Thus:

2x - 7      x + 4

--------- = ---------

   57          51

Cross multiplication results in 51(2x - 7) = 57x + 228, or

102x - 357 = 57x + 228

Combining like terms, we get:

45x = 585, and so x = 13.

Suppose that Clayton Kershaw of the Los Angeles Dodgers throws his fastball with a mean velocity of 94 miles per hour (mph) and a standard deviation of 2 mph and that the distribution of his fastball speeds can be modeled by a Normal distribution What percent of Kershaw’s fastballs will travel at least 100 mph?

Answers

Answer:

Step-by-step explanation:

ah,  probability,  so the std. deviation is 2 MPH,  so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 std. deviations  or  6 MPH to hit 100

99.7%  of throws fall into that area of with in 3 std. deviations so that means

0.3% fall outside also , 1/2 of those will 3 std. deviations slow while the other half is fast

so

0.15%  will be 100 or faster.... not many

0.15% is the percent of Kershaw’s fastballs will travel at least 100 mph.

What is Normal Distribution?

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

The standard deviation is 2 MPH,  so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 standard deviations  or  6 MPH to hit 100

99.7%  of throws fall into that area of with in 3 standard deviations  so that means

0.3% fall outside also , 1/2 of those will 3 standard deviations slow while the other half is fast

so 0.15%  will be 100 or faster

Hence 0.15 percent of Kershaw’s fastballs will travel at least 100 mph.
