Find the value of x.

Answer:

x=2

Step-by-step explanation:

We will use the secant-secant Formula:

(whole secant) x (external part) =         (whole secant) x (external part)

(1+x+4) * (x+4) = (11+x+1) * (x+1)

Combine like terms

(x+5) (x+4) = (x+12) (x+1)

FOIL

x^2 + 4x+5x + 20 = x^2 +  x+ 12x + 12

Combine like terms

x^2 + 9 x + 20 = x^2 + 13 x + 12

Bring everything to the left

x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)

x^2 + 9 x + 20- (x^2 + 13 x + 12) =0

Distribute the minus sign

x^2 + 9 x + 20- x^2 - 13 x - 12 =0

Combine like terms

-4x +8 = 0

Subtract 8 from each side

-4x+8-8=0-8

-4x=-8

Divide each side by -4

-4x/-4 = -8/-4

x=2

Answer: 31%

Step-by-step explanation: We need to find the amount deducted from the check which is $101.15. Keep in mind that this is the amount DEDUCTED, so if we add it to the net pay we will get the full amount which is $330.

Now we can do some math.

101.5 x 100 / 300 = 30.6515152% or 31%

The percentage of gross income going to taxes and FICA will be 38.75%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

To the nearest one percent, the percentage of gross income going to taxes and FICA is: 44% 31% 69% 11%

P = [(0.44 + 0.31 + 0.69 + 0.11) / 4] x 100

P = (1.55 / 4) x 100

P = 0.3875 x 100

P = 38.75%

The percentage of gross income going to taxes and FICA will be 38.75%.

Answer:

37.5 or 37 1/2

Step-by-step explanation:

The formula for finding surface area in a cube is A=6a^2

substituting 2.5 instead of a will result in this equation. A=6(2.5)^2

solving algebraically will then get you to your answer of 37.5

Answer:

Step-by-step explanation:

Each cube has six faces. All faces are congruent and each of them is a square.

The fromula of an area of a square is:

[tex]A=s^2[/tex]

s - length of a side of a square

We have

[tex]s=2\dfrac{1}{2}[/tex]

Convert it to a decimal

[tex]s=2\dfrac{1}{2}=2.5[/tex]

Substitute to the formula of an area of a square:

[tex]A=(2.5)^2=(2.5)(2.5)=6.25[/tex]

The Surface Area of a cube:

[tex]S.A.=6A[/tex]

Substitute:

[tex]S.A.=6\cdot6.25=37.5[/tex]

Answer:

-64

Step-by-step explanation:

Answer:

[tex]-64=64cos(\pi )+64i/ sin(\pi )[/tex]

Step-by-step explanation:

For a complex number a + bi, polar form is given by [tex]r(cos(0)+ i sin(0))[/tex], where [tex]r = \sqrt{a^2+b^2}[/tex] and [tex]a = atan(\frac{b}{a} )[/tex]

In this case, we have [tex]a = -64[/tex] and [tex]b=0[/tex]

Therefore, [tex]r = \sqrt{(-64)^2+(0)^2} =64[/tex]

Also, [tex]0 = atan(\frac{0}{-64} )+\pi =\pi[/tex]

Which means that, [tex]-64=64cos(\pi )+64i/ sin(\pi )[/tex]!!!

Answer:

78 degrees

Step-by-step explanation:

Mainly because the measure of the arcs intercepted by the interior angles equals 2 times those interior angles.

so arc DC =  2 * angle DBC = 2 * 51 degrees = 102 degrees.

We also see that because BD is a diameter the angle  BCD that intercepts it is 90 degrees because   half-circle arc BD = 2 * angle BCD

180 degrees = 2 * angle BCD

also we want arc BC.

we know that the total circle is the sum of all 3 arcs.

arc BC + (half-circle) arc BD + arc DC = 360 degrees

arc BC + 180  + 102 = 360 degrees.

arc BC =  360 - 180 - 102 = 78 degrees

Use a parameterization to find the flux [tex]\int\limits \int\limits_s \ F. \ n \ d \sigma[/tex] of F = z²i + xj - 2zk in the outward direction

(normal away from the x-axis) across the surface cut from the parabolic cylinder z = 16 -y²  by the planes x = 0 , x = 1, and z = 0 .

The flux is                  .

Answer:

[tex]-\frac{512}{3}[/tex]

Step-by-step explanation:

F(x,y,z) = (z² ,x , - 2z)

To find the flux across a surface : [tex]\int\limits \int\limits_s \ F. \ n \ dS = \int\limits \int\limits_D \ F. (r_u * r_v) \ dA[/tex]

The sphere z is given as =  16 -y²,    above x = 0 , x= 1, and z = 0

When z = 0 ⇒ 16 - y² = 0

⇒ y = ± 4

The parameterization is y=v⇒z= 16 -v²    and x= u

⇒ r = (x,y, z) = ( u,v,16 - v²)

with 0 ≤ u ≤ 1      and     -4 ≤  v ≤  4

However the normal vector can now be determined as :

[tex]r_u = (1,0,0) , \ \ \ r_v = (0,1, - 2v)[/tex]

[tex]n = r_u*r_v = \left[\begin{array}{ccc}i&j&k\\1&0&0\\0&1&-2v\end{array}\right] = (0,2v,1)[/tex]

[tex]\int\limits \int\limits_s \ F. \ n \ dS = \int\limits \int\limits_D \ F. (r(u,v)) .(r_u*r_v)dA[/tex]

[tex]=\int\limits^1_0 \int\limits^4_{-4} [(16-v^2)^2 , u , -2 (16-v^2)](0,2v,1)dvdu[/tex]

[tex]=\int\limits^1_0 \int\limits^4_{-4} [2uv-2(16-v^2))dvdu[/tex]

[tex]=\int\limits^1_0 (uv^2 -32v+ \frac{2v^3}{3})^ ^4}__{-4}} du[/tex]

[tex]=\int\limits^1_0 (u(16-16)-32(8)+\frac{2}{3}(128))du[/tex]

[tex]= \int\limits^1_0 (-\frac{512}{3})du[/tex]

[tex]= - \frac{512}{3}(u)^ ^1}__0[/tex]

= [tex]-\frac{512}{3}[/tex]

The flux of a vector field across a surface is calculated by computing the surface integral of the vector field in the direction normal to the surface. This involves parametrizing the surface and taking antiderivatives based on the defined area. The direction of the flux is crucial as it determines the sign of the flux.

To find the flux of the vector field upper Case Bold F across a surface, we need to compute the surface integral of upper Case Bold F in the given direction. For the given problem, the surface is defined by the parabolic cylinder z = 1 - y^2 and the planes x = 0, x = 1, z = 0. We parametrize this surface using two parameters x and y, with x ranging from 0 to 1, and y ranging from -1 to 1.

We then compute the surface integral by taking the antiderivative of the defined area with the boundaries of surface as the integral's bounds. This process might involve computation of multiple integrals if the surface is composed of multiple parts.

Note that the direction of the flux, which is normal away from the x-axis, is important for the calculation, as it determines the sign of the flux. The flux is positive if the angle between the vector field and the outward normal to the surface is less than 90 degrees, and negative otherwise.

Answer:

y=.75x (13 Times)

Step-by-step explanation:

y is the amount it will cost Montel to play the video game x amount of times, if Montel plays the game 2 times, 2x.75 is $1.50 so it would cost him $1.50 to play the game 2 times. However, we want to find how many times he can play with a $10 budget, so we must enter $10 as y and divide by .75 and we should get 13.33333. This means Montel will be able to play 13 times and will have 25 cents left over because 13 x .75 is $9.75

Step-by-step explanation:

Answer:

Step-by-step explanation:

What it means to "solve for a triangle" is to basically find ALL the missing parts, which in this case, are the lengths.

You are given the angles of the triangle, which we can use to help find the lengths.

By using sin, cos, and tan we can find the missing lengths

** quick side note, an easy way to remember how to use sin, cos, tan is SOH CAH TOA. In other words "for sine, multiply the opposite and hypotenuse, for cosine, multiply adjacent and hyp., and for tan, multiply opposite and adj.

start w/ solving for an angle (it doesn't matter which one but ill do A)

Bc you aren't given any side lengths, you have it a little easier by having to only use one method of SOH CAH TOA to solve. The method is sine

Using your calculator, type in sin(degree) or sin(51), and  you should get

= 0.777145 OR 0.8

** make sure your calculator is is DEGREES not RADIANS

Now do this for the rest of the angles:

sin(7)= 0.1

sin(10)= 0.2

You have all the lengths (0.8, 0.1, 0.2) add them together to find the perimeter and if you want to find the area use Bh/2. But to find the area you must have a height, which you don't have

To find the height use formula: sqrt/( S(S-A)(S-B)(S-C)

A, B, C are the sides you've found using sine, and S is 1/2( A+B+C) or fast math is 0.55.

Final answer:

To find out how many 1/3 inch cubes can fit into a 2 inch cube, calculate the volume of both cubes and divide the larger volume by the smaller. The result is 216 such cubes can fit into a 2 inch cube.

Explanation:

To determine how many 1/3 inch cubes can fit into a 2 inch cube, we first need to calculate the volume of the larger cube, which is 2 inches x 2 inches x 2 inches = 8 cubic inches. Next, we calculate the volume of the smaller cube which is (1/3 inch) x (1/3 inch) x (1/3 inch) = 1/27 cubic inch. To find how many smaller cubes fit into the larger one, we divide the volume of the larger cube by the volume of the smaller cube: 8 cubic inches / (1/27) cubic inch = 216. Therefore, 216 smaller cubes, each 1/3 inch on a side, can fit into a 2 inch cube.

Answer:

16 men would be needed to paint the room in 2 hours

Step-by-step explanation:

We can use proportion to solve the problem given, but first we need to determine whether it is a direct or indirect proportion.

If the number of men are increase, the time taken to do the work will decrease, If the number of men are decrease, the time taken to do the work will increase. Therefore, this is an indirect proportion.

We are going to arrange the data inversely.

Let x be the number of men needed to paint the room in two hours

8 hours =  2 hours

    x        = 4 men

Cross-multiply

2×x = 8×4

2x = 32

Divide both-side of the equation by 2

2x/2 = 32/2

x = 16 men

16 men would be needed to paint the room in 2 hours

Step-by-step explanation:

All we have to do is simply find the probability of selecting a triangle, find the  probability of selecting a circle and then add them together.

There are a total of 10 shapes in the box.

There are 3 triangles, so, the probability of picking a triangle is:

3/10

There are 2 circles, so, the probability of selecting a circle is:

2/10

Adding them together yields:

3/10 + 2/10 = 5/10 = 1/2

The probability of selecting a triangle or circle is 1/2.

Final answer:

By dividing the total cost of 5 fruit bars by 5, we get the cost per bar, which is $0.79. Then, dividing $12 by $0.79 per bar, we find that you can buy 15 bars with $12.

Explanation:

To determine how many frozen fruit bars can be purchased with $12 when 5 bars cost $3.95, we first need to calculate the cost per bar. We do this by dividing the total cost of 5 bars ($3.95) by the number of bars (5), giving us:

Cost per bar = $3.95 ÷ 5 = $0.79 per bar.

Next, we divide the total amount of money available ($12) by the cost per bar to find out how many bars can be bought:

Number of bars = $12 ÷ $0.79 per bar

When we do the calculation, we get:

Number of bars = 15.19 bars

Since we can't buy a fraction of a bar, we round down to the nearest whole number:

Number of bars that can be bought = 15 bars

Therefore, with $12, you can buy 15 frozen fruit bars.

Answer:

The answer to this question can be defined as follows:

net paid interest = $ 655. 04

Total cost = $ 4955.04

Step-by-step explanation:

Given values:

loan amount = $ 4,300

monthly payment = $ 206.46

interest rate = 14 %

Time = 2 years

Solution:

yearly payment = one month amount × 12

1 year payment = $ 206.46 × 12

1 year payment =  $2477.52

because Time is 2 year then payment is = $2477.52 *2

2 year payment = $ 4955.04

net interest paid  = total payment - loan amount

                            = $ 4955.04 - $4300

                            = $ 655.04

total  cost = $ 4955.04

net paid interest = $ 655.04

The total cost of repayment and the interest should be $4,955.04 and $655.04.

Since

loan amount = $ 4,300

monthly payment = $ 206.46

interest rate = 14 %

Time = 2 years

Now

yearly payment = one month amount × 12

So,

= $ 206.46 × 12

=  $2477.52

Now the two year payment should be

= $2477.52 *2

= $ 4955.04

Now

net interest paid  = total payment - loan amount

= $ 4955.04 - $4300

= $ 655.04

hence, The total cost of repayment and the interest should be $4,955.04 and $655.04.
