In right triangle ABC, C is the right angle. What does sinB equal? options: sinB, cosB, cosA, not enough information

Answer:

7/16

Step-by-step explanation:

Using an ideal gas equation to solve the problem. Then the original volume is 17.67 liters.

An ideal gas is a theoretical composed of a set of randomly moving gas particles that interact only through elastic collision.

Given

A balloon containing 0.500 mol at 0. 00°C and 65.0 kPa pressure are expanded by adding more argon.

Pressure (P) = 65 kPa

Mole (n) = 0.5 mol

Temperature (T) = 0 °C = 273.15 K

Universal gas constant (R) = 8.317 L.kPa/mol.K

We know the ideal gas equation

[tex]\rm PV =nRT\\\\V \ \ = \dfrac{nRT}{P}[/tex]

Put the values, we have

[tex]\rm V = \dfrac{0.5*8.317*273.15}{65}\\\\V = 17.67[/tex]

Thus, the original volume is 17.67 liters.

Answer:

Step-by-step explanation:

to find the mean is another way of saying to find the average. To do this we add all the listed values(45,52,17,63,57,42,54,58) then divide them by how many values we are given which in this case is 7. so the mean would be 49. now to find the median we must first put the values in numeric order(17,42,45,52,54,57,58,63) then see the number in the middle or in cases or even number of values we find the two values in the middle of the set then we add them together and divide by two. which would be 53. now to find the mode we simply find the most reoccurring number in the set and seeing as there are no repeated values in this set there is no mode.

Answer:

I fell like guiding you would be better.
First, help yourself by labelling all vertex's (there should be 5 so a,b,c,d,e).

You know that they are 2 sets of similar triangles cuz there is a 70 degree on in both and a common on

Then all you need to do is set up the proportion.

I can't give you the answer cuz I don't have much time, but I feel like you can figure it out. If this helped you, pls rate it decent, but if not just 1-star it I don’t care

The GCF of 35 and 50 is 5

Answer:

5% of 20 is 1

Answer:

  4. 11/6, 121/36

  5. 5/8, 25/64

  6. 4/7, 16/49

  7. 14/9, 196/81

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding legs:

  perimeter ratio = red leg/blue leg

The area ratio is the square of that:

  area ratio = (perimeter ratio)²

__

perimeter ratio = 11/6

area ratio = (11/6)² = 121/36

__

perimeter ratio = 5/8

area ratio = (5/8)² = 25/64

__

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

__

perimeter ratio = 14/9

area ratio = (14/9)² = 196/81

Answer:

6 cm²

Step-by-step explanation:

The shorter sides are base and height.

3 x 4 / 2

= 6

We have: a² + b² = 3² + 4² = 9 + 16 = 25 = 5² = c²

=> triangle ABC is a square triangle

=> the area of the triangle ABC is: a × b ÷ 2 = 3 × 4 ÷ 2 = 6 (cm²)

Answer: 6 cm²

Ok done. Thank to me :>

Answer:

x = ± √11 i

Step-by-step explanation:

x^2 + 5 + 6 = 0

subtract 6 and 5 from both sides

x^2 = -11

find the square root of both sides

x = ± √-11

x = ± √11 √-1

x = ± √11 i

Answer:

the answer for 1 1/3 is O 4/3

5 2/5 is T  28/5

2 4/5 is D  14/5

Step-by-step explanation:

All you have to do is multiply the whole number by the denominator and then add the numerator and the denominator stays the same.

Like on the second one you would multiply the 5 by the denominator which is also five then add the numerator,1, and that gives you the top number and the bottom one stays the same.

Oblique triangle : any triangle that is not a right triangle

Use the sine rule to find one of the unknown interior angles:

[tex]\dfrac{sin(A)}{a}=\dfrac{sin(B)}{b}=\dfrac{sin(C)}{c}[/tex]

where A, B and C are the interior angles of a triangle, and a, b and c are the sides opposite to the interior angles.

[tex]\implies \dfrac{sin(58)}{12}=\dfrac{sin(B)}{6}[/tex]

[tex]\implies sin(B)=\dfrac{6sin(58)}{12}=0.4240240481...[/tex]

[tex]\implies sin(B)=25.08890446...=25 \textdegree \ \ \textsf{(nearest whole)}[/tex]

Sum of interior angles of a triangle = 180°

⇒ Missing angle = 180 - 58 - 25 = 97°

Answer: the answer is x=38

Step-by-step explanation:

X-18=20 we see that 18 is being SUBTRACTED from the x which means we have to do the opposite of subtraction is addition so 20+18=38

To check: you can plug 38 for x and subtract it from 18

Demonstration: 38-18=20

X = 38

Step-by-step explanation:

X-18 = 20

we move the constants (numbers) to one side and keep the variable, unknown on the other side

X= 20+18 (we change the sign whenever we move something to the opposite side)

x= 38

Step-by-step explanation:

Answer:

28,370.38

Step-by-step explanation:

If accumulated but not compounded

.06 * 20,000 = 1200 per year

1200 * 6 = 7200 total interest

7200 + 20,000 = 27,200

If compounded annually

20,000 * 1.06^6 = 20,000*1.4185 = 28,370.38

just an addtion to the reply above.

[tex] \frac{2(3 - x)^{ \frac{5}{2} } }{5} - \frac{2(3 - x)^{ \frac{3}{2} } }{3} + C[/tex]is the answer

Step-by-step explanation:-

Given:

[tex]{\int {(x-2)\sqrt{3-x}} \ dx }[/tex]

Differentiate on both sides,

[tex]{\int {(x-2)\sqrt{3-x}} \ dx },u = 3 - x[/tex]

Isolate and substitute back,

[tex]{\int {(x-2)\sqrt{3-x}} \ \times ( - 1) du },u = 3 - x[/tex]

Substitute back,

[tex]{\int ( - ( - u + 3 - 2) \sqrt{u})du }[/tex]

Applying property of integral ∫ kf(x)dx = k ∫ f(x)dxdx,

[tex] - ∫ ( - u + 3 - 2) \sqrt{u} \: du,u = 3 - x[/tex]

Combining like terms,

[tex]- ∫ ( - u +1) \sqrt{u} \: du,u = 3 - x[/tex]

Now applying distributive property,

[tex]- ∫ (( - u +1) \sqrt{u}) \: du,u = 3 - x[/tex]

[tex] = > - ∫ ( - \sqrt{u} \times u + \sqrt{u} )\: du,u = 3 - x[/tex]

Converting to exponential form,

[tex]- ∫ ( - u^{ \frac{1}{2} } \times u + u^{ \frac{1}{2} } )\: du,u = 3 - x[/tex]

Multiplying the first two monomuals after integral, we get,

[tex]- ∫ ( - u^{ \frac{3}{2} } + u^{ \frac{1}{2} } )\: du,u = 3 - x[/tex]

Now applying the prperty of ∫ f(x) + g(x)dx = ∫ f(x)dx + ∫ g(x)dx,

[tex] - ( - ∫u^{ \frac{3}{2} } \: du + ∫u^{ \frac{1}{2} } \: du),u = 3 - x[/tex]

Now integrate the power rule,

[tex] - ( - \frac{u^{ \frac{5}{2} }}{ \frac{5}{2} } + \frac{u^{ \frac{3}{2} }}{ \frac{3}{2} } ),u = 3 - x[/tex]

Divide the fractions by multiplying its reciprocals,

[tex] - ( - u^{ \frac{5}{2} } \times \frac{2}{5} + u^{ \frac{3}{2} } \times \frac{2}{3}),u = 3 - x[/tex]

Now write as single fractions,

[tex] - ( - \frac{2u^{ \frac{5}{2} } }{5} + \frac{2u^{ \frac{3}{2} } }{3})[/tex]

Removing the parentheses,

[tex] \frac{2u^{ \frac{5}{2} } }{5} - \frac{2u^{ \frac{3}{2} } }{3},u = 3 - x[/tex]

Substitute back,

[tex] \frac{2(3 - x)^{ \frac{5}{2} } }{5} - \frac{2(3 - x)^{ \frac{3}{2} } }{3} [/tex]

Now adding the constant of integration C∈R,

[tex] \frac{2(3 - x)^{ \frac{5}{2} } }{5} - \frac{2(3 - x)^{ \frac{3}{2} } }{3} + C[/tex]

Hence, the answer.
