WILL GIVE BRAINLIEST What It The Value Of Y?

Answers

Answer 1

Answer:

C 40

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

y+10 + 2y + 50 = 180

Combine like terms

3y + 60 =180

Subtract 60 from each side

3y+60-60 = 180-60

3y = 120

Divide by 3

3y/3 = 120/3

y = 40

Answer 2

The sum of all the angles of a triangle is 180 degrees. To solve for y you can make a formula of the sum of the angles equal to 180 like so...

y + 10 + 2y + 50 = 180

Now you must combine like terms. This means that first numbers with the same variables (y) must be combined...

(y + 2y) + 10 + 50 = 180

3y + 10 + 50 = 180

Combine like terms 10 and 50...

3y + 60 = 180

Now bring 60 to the left side by subtracting 60 to both sides (what you do on one side you must do to the other). Since 60 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

3y + 60 - 60 = 180 - 60

3y + 0 = 120

3y = 120

Next divide 3 to both sides to finish isolating x. Since 3 is being multiplied by x, division (the opposite of multiplication) will cancel 3 out (in this case it will make 3 one) from the left side and bring it over to the right side.

3y / 3 = 120 / 3

y = 40

Use the law of sines to find the value of a.



Law of sines:

What is the best approximation of the value of a?

2.4 cm
2.7 cm
3.0 cm
3.3 cm

Answers

Answer:

3.0 cm

Step-by-step explanation:

The Law of Sines states the relationship between the sides and the angles of non-right (oblique) triangles.

In the given triangle,the following relation holds;

[tex]\frac{4.7}{sin(95)}=\frac{a}{sin(40)}\\\\a=\frac{4.7}{sin(95)}*sin(40)\\\\a=3.03[/tex]

Answer:

Option C. a = 3.0 cm

Step-by-step explanation:

We have to find the value of a from the given triangle ABC.

By applying sine rule in ΔABC

[tex]\frac{sin95}{4.7}=\frac{sin40}{a}[/tex]

Now we cross multiply in the given equation.

a(sin95°) = 4.7(sin40°)

a(0.9962) = 4.7(0.6428)

a = [tex]\frac{4.7(0.6428)}{0.9962}[/tex]

a = 3.03 cm ≈ 3.0 cm

Therefore, a = 3.0cm Option C. will be the answer.

Consider a triangle ABC like the one below. Suppose that A = 27°, C = 78°, and b = 66. (The figure is not drawn to scale.) Solve
the triangle.

Answers

We don't get to see the figure but we don't need it.

The remaining angle B is

B = 180 - 27 - 78 = 75°

The Law of Sines gives the remaining sides

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

[tex]a = \dfrac{b \sin A}{\sin B} = \dfrac{66 \sin 27}{sin 75} \approx 31.0203[/tex]

[tex]c = \dfrac{b \sin C}{\sin B} = \dfrac{66 \sin 78}{sin 75} \approx 66.8350[/tex]

Answer: B=75°, a=31.0, c=66.8

No need for "or" on this one.  That happens when we know the sine of an angle so there are two possibilities for the angle, an acute one and an obtuse one that's supplementary.

Shawna and her best friend Keisha go shopping. The function p(t) = 3x +2x-4x2+ 21 represents how much money each girl spent based on the number of hours they were shopping. If Shawna and Keisha each go shopping for 2 hours, how much money did they spend together?

Answers

Answer:

[tex]\$30[/tex]

Step-by-step explanation:

we have

[tex]p(t)=3x+2x-4x^{2}+21[/tex]

Find the amount of money that each girl spent

For t= 2 hours

[tex]p(2)=3(2)+2(2)-4(2)^{2}+21[/tex]

[tex]p(2)=10-16+21[/tex]

[tex]p(2)=\$15[/tex]

Find the amount of money that they spend together

Multiply by 2 the amount of money that each girl spent

[tex](2)\$15=\$30[/tex]

Shawna and Keisha spent $30 together when each of them went shopping for 2 hours.

It seems there might be a typo in the function p(t) you provided. It should be[tex]\( p(t) = 3t + 2t - 4t^2 + 21 \)[/tex], where t represents the number of hours spent shopping.

To find out how much money Shawna and Keisha spent together when each of them went shopping for 2 hours, we need to evaluate the function p(t)  at [tex]\( t = 2 \)[/tex] and then add the results.

Let's plug in t=2 into the function p(t):

[tex]\[ p(2) = 3(2) + 2(2) - 4(2)^2 + 21 \][/tex]

[tex]\[ = 6 + 4 - 16 + 21 \][/tex]

[tex]\[ = 10 - 16 + 21 \][/tex]

[tex]\[ = 15 \][/tex]

Multiply by 2 since $15 is for each girl = 2*$15= $30

The sum of two angles measures is 95 degrees. Angle 2 is 40 degrees smaller than 2 times angle 1. What are the measures of the two angles in degrees?

Answers

Answer:

<1 = 45

<2 = 50

Step-by-step explanation:

Let <1 = x

Let <2 = y

=============

x + y = 95

y = 2*x - 40

=============

I think the easiest way to do this is to substitute the second or bottom equation into the top equation. Substitute for y

x + 2x - 40 = 95                    Combine like terms on the left.

3x - 40 = 95                          Add 40 to both sides.

3x -40+40 = 95+40              Combine

3x = 135                                 Divide by 3

x = 45

=================

Now use the top equation to solve for y

x + y = 95

45 + y = 95                             Subtract 45 from both sides.

45 - 45 + y = 95 -45               Combine

y = 50

"When the fundraiser began, 600 people wanted to purchase the dance troupe’s T-shirts at $12 per T-shirt, but as the group increased the price of their T-shirts, they noticed a fall in the demand. For every $1 increase in price, the demand fell by 50 shirts. The dance troupe’s initial supply was short by 210 T-shirts which corresponded to an initial price of $9.75. For every $1 increase in price, they ordered 40 more T-shirts. Write a system of linear equations to represent both the demand and supply for the T-shirts. Let q represent the quantity of T-shirts and p represent the price."

Answers

Answer:

Demand: q = -50p + 1200

Supply: q = 40p

Step-by-step explanation:

First let's define our variables.

q = quantity of T-shirts

p = price

We know that when p = 12, q = 600.  When p increases by 1, q decreases by 50.  So this is a line with slope -50 that passes through the point (12, 600).  Using point-slope form to write the equation:

q - 600 = -50 (p - 12)

Converting to slope-intercept form:

q - 600 = -50p + 600

q = -50p + 1200

Similarly, we know that when p = 9.75, q = 600 - 210 = 390.  When p increases by 1, q increases by 40.  So this is a line with slope 40 that passes through the point (9.75, 390).  Using point-slope form to write the equation:

q - 390 = 40 (p - 9.75)

Converting to slope-intercept form:

q - 390 = 40p - 390

q = 40p

A cylinder has a base diameter of 16 inches and a height of 18inches. What is the volume in cubic inches, of the nearest tenths place ?

Answers

Answer:

3619.11 cubic inches

Step-by-step explanation:

volume of a cylinder is [tex]V=\pi r^2h[/tex]

diameter is 16 in, so radius (r) is 8 in

plug in values: [tex]V=\pi 8^2(18) = 3619.11[/tex] cubic inches

The volume of a cylinder with a diameter of 16 inches and a height of 18 inches is calculated using the formula V = πr²h, which results in approximately 3617.3 cubic inches when rounded to the nearest tenths place.

To calculate the volume of a cylinder, we use the formula V = πr²h. Given that the diameter of the cylinder is 16 inches, which means its radius (r) is half of that, 8 inches. The height (h) of the cylinder is given as 18 inches. To find the volume, first square the radius, then multiply by π (approximated as 3.14 for this purpose), and then by the height.


So, the calculation looks like this:

Volume = π × (8 inches)² × 18 inchesVolume = 3.14 × 64 inches² × 18 inchesVolume = 3.14 × 1152 inches³Volume ≈ 3617.28 cubic inches

Therefore, the volume of the cylinder, rounded to the nearest tenth place, is 3617.3 cubic inches.

A company manufactures its product at a cost of $0.50 per item and sells it for $0.85 per item daily overhead is $600 how many items must be manufactured each day in order for the company to break even

Answers

so the company has an overhead of $600, usually that involves premises leasing and industrial equipment for the manufacturing of the product, that's cost.  The cost to make each item is 50 cents, so if the company produces "x" items, their cost is 0.5x total.

so our cost equation C(x) = 0.5x + 600   <---- items' cost plus overhead.

the company sells the product for 85 cents, so if they sell "x" items, their total revenue or income will be 0.85x.

so our revenue equation is simply R(x) = 0.85x.

as you already know, the break-even point is when.... well, you break even, no losses but no gains either, how much you take in is the same amount that you shelled out, namely R(x) = C(x).
