Answer:

Porportional

Step-by-step explanation:

-1 x = -15 y

-7 x -15 = -105, correct

-9 x -15 = -135, correct

Because all are correct, this is porportional. This means that there is a unit rate and if this were graphed, the line would be straight.

Answer:

45 cookies

Step-by-step explanation:

Use a unit rate.

With a unit rate, we find the number of cookies that are baked using 1 scoop.

(30 cookies)/(6 scoops) = 5 cookies/scoop

The rate of 30 cookies to 6 scoops is the same as the unit rate of 5 cookies/scoop.

Now we multiply the unit rate by 9 scoops.

9 scoops * 5 cookies/scoop = 45 cookies

Answer: 45 cookies

Step-by-step explanation:

2c+10=30

2c+10−10=30−10

2c=20

2c÷2=20÷2

Answer: c=10

Answer:

10

Step-by-step explanation:

2c + 10 = 30

so we take 10 to the other side to become - 10.

Therefore 2c = 30 - 10

= 20

Divide both sides by the coefficient of c that's 2

2c = 20

c = 10

Answer:

Rhombus Side = sqr root [(34 / 2)^2 + (30 / 2)^2]

Rhombus Side = sqr root [17^2 + 15^2]

Rhombus Side = sqr root [289 + 225}

Rhombus Side = sqr root [514]

Rhombus Side = 22.6715680975

Rhombus Perimeter = side * 4 = 90.68627239  cm

Answer:

sin([tex]\frac{7\pi }{4}[/tex] ) = -[tex]\frac{\sqrt{2} }{2}[/tex]

Step-by-step explanation:

If cos(theta) = [tex]\frac{\sqrt{2} }{2}[/tex], then theta should equal [tex]\frac{\pi }{4}[/tex] or [tex]\frac{7\pi }{4}[/tex]  since both angles are on the right side of the origin, meaning the cosine would be positive. However, it states that the angle theta terminates at quadrant IV so the only angle that would meet this criteria is [tex]\frac{7\pi }{4}[/tex] .

So theta should equal [tex]\frac{7\pi }{4}[/tex] .

Now that we have theta, all you have to do is find the value of sine by plugging it in.

sin([tex]\frac{7\pi }{4}[/tex] ) = -[tex]\frac{\sqrt{2} }{2}[/tex]

Answer:

richard is 22 and teo is 9

Step-by-step explanation:

The volume between the cone and the sphere is approximately 23.55 cubic units.

We are given that;

[tex]X= sqrt(y^2 + z^2)[/tex]

[tex]x^2 + y^2 + z^2 = 16.[/tex]

Now,

To find the volume between the cone and the sphere, we can use a triple integral in spherical coordinates.

The cone corresponds to the equation [tex]$\rho = 2\cos(\phi)$[/tex], where [tex]$\rho$[/tex] is the radial distance, [tex]$\phi$[/tex]is the polar angle, and [tex]$\theta$[/tex] is the azimuthal angle. The sphere corresponds to the equation [tex]$\rho = 4$[/tex]. The limits of integration are:

[tex]$0 \leq \theta \leq 2\pi$$0 \leq \phi \leq \frac{\pi}{4}$$2\cos(\phi) \leq \rho \leq 4$[/tex]

The volume element in spherical coordinates is [tex]$\rho^2\sin(\phi)d\rho d\phi d\theta$[/tex]

Therefore, the volume is:

[tex]$V = \int_{0}^{2\pi}\int_{0}^{\frac{\pi}{4}}\int_{2\cos(\phi)}^{4}\rho^2\sin(\phi)d\rho d\phi d\theta$[/tex]

Evaluating this integral, we get:

[tex]$V = \frac{32}{3}\pi - 8\sqrt{2}\pi + 16\pi$[/tex]

Therefore, by volume of cone the answer will be 23.55 cubic units.

The approximate solution to the trigonometric inequality will be 0<=x<0.7896. Option A is correct.

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

Given inequality;

tan(x/4)<1/5

x/4 = tan⁻¹(1/5)

0<=x<0.7896

The approximate solution to the trigonometric inequality will be 0<=x<0.7896.

If your doing 4 thousand and some hundreds then the answer is 19 hundred, But if your doing just hundreds the answer is 59 hundreds.

Step-by-step explanation

5900/100 = 59

Answer:

Amount borrowed from friend = 4000

From Bank = 8000

From insurance = 3200

Step-by-step explanation:

Given that:

Amount borrowed = $15200

Let amount borrowed from friend = x

x at 5% = 0.05x

From Bank = 2x at 8% = 0.08*2x = 0.16x

From insurance = 15200 - (x + 2x) at 4%

From insurance = 15200 - 3x at 4% ; (15200 - 3x)* 0.04 = 608 - 0.12x

Interest paid in first year = $968

Simple interest = principal * rate * time

968 =

968 = (0.05x + 0.16x + 608 - 0.12x)

968 - 608 = 0.05x + 0.16x - 0.12x

360 = 0.09x

x = 360 / 0.09

x = 4000

Hence,

Amount borrowed from friend = 4000

From Bank = 2x = 4000 * 2 = 8000

From insurance = 15200 - (4000 + 8000) = 3200

Answer:

[tex]\cos(69)[/tex]

Step-by-step explanation:

We will use the co-function identity for sine, where:

[tex]\sin(x)=\cos(90-x)[/tex]

Since sin(21)=0.358=cos(x). This means that:

[tex]21=90-x[/tex]

Solve for x. Add x to both sides:

[tex]x+21=90[/tex]

Subtract 21 from both sides:

[tex]x=69\textdegree[/tex]

Hence:

[tex]\sin(21)=\cos(69)\approx0.358[/tex]

106.33

Step-by-step explanation:

after decimal you have .3 tenths 2 hundredths 7 thousandths

to round to the nearest hundredths look at thousandths 7 becasuse is greater then 5 then you round up

106.327 is rounded to 106.33

Answer:

your answer is 106.3

Step-by-step explanation: so first you do this

[tex]106.327\\3 =tenths\\2= hundredths[/tex]

so when you round  if it is 5 or above you round up if it is 4 or below leave it alone

so the final answer is 106.3

when you round the 27 is removed and this is what you have left.

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Total number of units= 11,300

Total overhead= 6,200 + 188,000 + 134,000 + 29,000 + 224,750= $581,950

To calculate the predetermined manufacturing overhead rate we need to use the following formula:

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= 581,950 / 11,300

Predetermined manufacturing overhead rate= $51.5 per unit

Now, we can calculate the total cost of making 2,600 units:

Total cost= (82 + 66 + 51.5)*2,600

Total cost= $518,700
