A = kb

12 = k15
divide equation by 15 to make k the subject.
k = 4/5 or 0.8

a = kb
a = 0.8 x 12
a = 9.6

(0.6 as a fraction is 3/5)

therefore, a = 9 and 3/5

The sets A, B, and C are defined as follows:
PilotLPTM [1.2K]

The element of B × A × C is equivalent to the element of  A × B × C.

B × A × C = {tall foam nonfat, tall foam whole, tall no-foam nonfat, tall no-foam whole, grande foam non fat, grande foam whole, grande no foam nonfat, grande no foam whole, venti foam nonfat,, venti foam whole, venti nofoam nonfat, venti nofoam whole}

For the element of B × C

B × C = {foam nonfat, foam whole, no foam nonfat, no foam whole}

<h3>Product of sets</h3>

Given the following sets

A = {tall, grande, venti}

B = {foam, no-foam}

C = {non-fat, whole}

The set of A * B is expressed as:

A * B = {tall foam, tall no foam, grande foam, grande no foam, venti foam, venti nofoam}

A × B × C =  {tall foam nonfat, tall foam whole, tall no-foam nonfat, tall no-foam whole, grande foam non fat, grande foam whole, grande no foam nonfat, grande no foam whole, venti foam nonfat,, venti foam whole, venti nofoam nonfat, venti nofoam whole}

The element of B × A × C is equivalent to the element of  A × B × C.

B × A × C = {tall foam nonfat, tall foam whole, tall no-foam nonfat, tall no-foam whole, grande foam non fat, grande foam whole, grande no foam nonfat, grande no foam whole, venti foam nonfat,, venti foam whole, venti nofoam nonfat, venti nofoam whole}

For the element of B × C

B × C = {foam nonfat, foam whole, no foam nonfat, no foam whole}

The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?
spayn [35]

Answer:

it is a right triangle.

Step-by-step explanation:

you would solve by using pythagorean theorem. Firstly you would find the square roots. Then write the pythagorean theorem out replacing the variables with the corresponding numbers. All you do for this is find the greatest number and that is c. Lastly you would add the square roots of a and b, if this equals 28 then they are equal. Ask more questions if I did not explain this clearly.

the Wright flyer was the first successful powered aircraft a model was made to display in a museum with the length of 35 cm and
Savatey [412]
To compare the displayed Wright flyer in the museum with the actual plane, we have to compute for the ratio of the corresponding parameter. In this item, for both the display and the actual plane, we are given with the length. Computing for the ratio gives us,
    ratio = length of the model / length of the actual plane

Length of the model = 35 cm
We need to calculate for the length of the model in ft.
    length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
   length of the model = 1.148 ft

Going back to the equation for the ratio,
   ratio = (1.148 ft)/21 ft
   ratio = 0.055

Hence, the dimensions used in the model is equal to 0.055 times the actual dimensions.

Error may occur because of the number of significant figures considered for rounding up or down of the answers after each calculation.
