sin=opposite/Hypotonouse

80²+60²=hyp²

hyp=100

sinФ=60/100=3/5

Answer:

b. 3/5

Step-by-step explanation:

Using the pythagorean theorem, side AB is 100 m long.

Sine equals opposite over hypotenuse. In this case CB (60) is the opposite and AB (100) is the hypotenuse.

Sine for angle A = 60/100 = 3/5

Answer:

5

Step-by-step explanation:

You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.

It's the quadratic formula

x =  [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]

The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.

a is the coefficient of the first term in the expression, b is the second and c is the third.

so we get[tex]x = \frac{-(-10) +- \sqrt{(-10)^2 - 4(1)(24)} }{2(1)}[/tex] , which is the same as

[tex]x = \frac{10 + \sqrt{100 - 24(4)} }{2}[/tex]

and

x = [tex]x = \frac{10 - \sqrt{100 - 24(4)} }{2}[/tex]

The top part simplifies to [tex]\frac{10 + \sqrt{100 - 72} }{2} = \frac{10 + 6}{2} = 5[/tex], which is your answer.

Given:

Total number of coins (Quarters and dimes) = 60

Total amount = $12.45

To find:

The number of quarters and dimes.

Solution:

Let x be the number of quarters and y be the number of dimes.

We know that,

1 quarter = 0.25 dollar

1 dime = 0.10 dollar

Total coins: [tex]x+y=60[/tex]               ...(i)

Total amount: [tex]0.25x+0.10y=12.45[/tex]             ...(ii)

From (i), we get

[tex]y=60-x[/tex]          ...(iii)

Putting this value in (ii), we get

[tex]0.25x+0.10(60-x)=12.45[/tex]

[tex]0.25x+6-0.10x=12.45[/tex]

[tex]0.25x-0.10x=12.45-6[/tex]

[tex]0.15x=6.45[/tex]

Divide both sides by 0.15.

[tex]x=\dfrac{6.45}{0.15}[/tex]

[tex]x=43[/tex]

Putting x=43 in (iii), we get

[tex]y=60-43[/tex]

[tex]y=17[/tex]

So, the number of quarters is 43 and the number of dimes is 17.

Therefore, the correct option is b.

Hey!

So what it's asking for is the slope of the line. You can figure this out by finding two solid points on the line, such as (0,-1) and (4,2).

Knowing that these are two solid points, you can use the Rise/Run method to get the answer. The rise is how many units the slope rises (+) or falls (-) when getting to the next point. The run is how many units to the left or right it goes.

By following this, the slope is 3/4

Answer:

[tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Step-by-step explanation:

The computation is shown below:

Nuts used [tex]= 5 \frac{1}{3} = \frac{16}{3}[/tex]

Raisins used [tex]= 2 \frac{3}{4} = \frac{11}{4}[/tex]

Now the difference between them is

[tex]= \frac{16}{3} - \frac{11}{4}\\\\= \frac{64 - 33}{12} \\\\= \frac{31}{12}[/tex]

Hence, [tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Step-by-step explanation:

honestly in my opinion thats my answer but it might be wrong. you could add or multiply it, I added the ingredients 3 times but it’s more simple to multiply each by 3.

3 times 3 = 9

4 times 3 = 12

2 times 3 = 6

1 times 3 = 3

C: 6 greeting cards for $23.40

Step-by-step explanation:

Answer:

m<ABC = 116°

m<CDE = 67°

Step-by-step explanation:

✔️m<ABC = 180 - m<BAD (adjacent angles of a parallelogram are supplementary)

m<ABC = 180 - 64° (Substitution)

m<ABC = 116°

✔️m<CDA = m<CDE + m<ADE (angle addition postulate)

m<CDA = m<CDE + 49°

m<CDA = m<ABC (opposite angles of a parallelogram are congruent)

m<CDE + 49° = 116° (substitution)

m<CDE = 116° - 49° (Substraction property of equality)

m<CDE = 67°

Step-by-step explanation:

(10^2-6^2) gives the hypotenuse of the smaller triangle therefore we get 8 units for that side.looking for the value of x

(8^2-3^2)=x^2

(64-9)=x^2

Answer: if the irrational sum of a plus the square root of b is the root of a polynomial with rational coefficients, then a minus the square root of b, which is also an irrational number, is also a root of that polynomial.

Step-by-step explanation: Look it up

The resultant force in the example presented is approximately 774 pounds.

The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics.

Formally speaking, the size of an object is the visible outcome of an ordering—of the class of objects to which it belongs.

Consider the following scenario: the force is 10 N in the east.

The direction is indicated by "towards the east," while the force is indicated by "10."

Magnitude can be thought of as simply the "value" or "amount" of any physical quantity.

So, an object is under the influence of two forces with respective magnitudes of 300 pounds and 450 pounds and an angle of 60 degrees between them.

F₁=300 pounds, F₂=450 pounds and θ=60°

Fr=√300²+450²+2×300×450×cos60°

= √90000+502500+13500×0.5

= √90000+502500+6750

= √599250

= 774 pounds

Therefore, the resultant force in the example presented is approximately 774 pounds.

Answer:

Store C

Step-by-step explanation:

store a is selling 10 pencils for $2.50

$2.50 divided by 10 is 25 cents

so the price for store a is 25 cents per pencil

store b is selling 50 pencils for $6.00

$6.00 divided by 50 is 12 cents

so the price for store b is 12 cents per pencil

store c is selling 100 pencils for $8.25

$8.25 divided by 100 is 8.25 cents

obviously you can't give someone .25 cents so round it down to 8

so the price for store c is 8 cents per pencil

store d is selling 250 pencils for $21.25

$21.25 divided by 250 is 8.5 cents

which rounds up to 9 cents per pencil

Store c has the lowest price for one pencil
