Answer:

The answer would be 0.99/1 pound

Step-by-step explanation:

There might be two ways to go about this

(1) I am going to assume that we can construct a second (reference) triangle - and you confirmed that it is ok to use trigonometry on that, and then we use the relationship between areas of similar triangles to get what we want. I choose a triangle DEF with same angles, 15, 75, and 90 degrees, and the hypotenuse DE a of length 1 (that is a triangle similar to ABC). I use sin/cos to determine the side lengths: sin(15)=EF and cos(15)=DF and then compute the area(DEF) =EF*DF/2. This turns out to be 1/8 = 0.125.

Now one can use the area formula for similar triangles to figure out the area of ABC - this without trigonometry now: area(ABC)/area(DEF)=(12/1)^2

so area(ABC)=144*area(DEF)=144*0.125=18

(2) Construct the triangle ABC geometrically using compass, protractor, and a ruler. Draw a line segment AB of length 12. Using the compass draw a (Thales') semi-circle centered at the midpoint of AB with radius of 6. Then, using the protractor, draw a line at 75 degrees going from point B. The intersection with the semicircle will give you point C. Finally. draw a line from C to A, completing the triangle. Then, using ruler, measure the length BC and AC.

Calculate the area(ABC)=BC*CA/2, which should come out close to 18, if you drew precisely enough.

Answer: 18 square cm

Step-by-step explanation:

*picture very note to scale im sorry lol*

Given: △ABC, m∠C=90°, m∠B=75°, AB=12 cm

m∠A = 15° (sum of all angles in a triangle is 180 degrees and 180-90-75=15)

CM - median to hypotenuse

CL - altitude

m<CLB = m<CLM = 90 degrees (def of altitude)

CM=MA=MB=1/2 AB = 6 cm (median to hypotenuse theorem)

m<MBC=m<BCM=75 degrees (base angles theorem of iso triangle)

m<BMC = 30 degrees (sum of all angles in a triangle, 180-75-75 = 30)

m<LCM = 60 degrees (sum of all angles in a triangle of triangle LCM, 180-90-30=60)

so now we know that triangle LCM is a 30-60-90 triangle with a hypotenuse of CM (6 cm)

LC = 1/2 of MC = 3 cm (leg opposite to 30 degree <)

So now we know that the height (altitude) of the triangle is 3 cm and the length is 12 cm.

Then, we can find the area by doing the (height * length)/2 = (3*12)/2, which brings us to our answer of 18 cm.

(I have answered this question about half an hour before - repeating here)

In order to show the correct time again, the clock has to be exactly 12 hours, or 12*60=720 minutes, behind. With 2 minutes per 3 hours, the clock will have to run for 3 * 720/2 = 1080 hours. 1080 hours = 45 days. The shortest interval the clock need to show the correct time is 45 days.

The shortest interval of time after which the clock will show the correct time is 1.5 hours.

To find the shortest interval of time after which the clock will show the correct time, we need to determine the total time it takes for the clock to lose 2 minutes and reset to the correct time. Since the clock loses 2 minutes every 3 hours, it loses 1 minute per 1.5 hours. Therefore, it will take 1.5 hours for the clock to lose 2 minutes and show the correct time again. So, the shortest interval of time is 1.5 hours.

(a)

[tex]10^{5}[/tex] (1.2 + (5.35 × [tex]10^{1}[/tex]))

= [tex]10^{5}[/tex] (1.2 + 53.5)

= 54.7 × [tex]10^{5}[/tex] = 5.47 × [tex]10^{1}[/tex]× [tex]10^{5}[/tex] = 5.47 × [tex]10^{6}[/tex]

(b)

[tex]10^{-3}[/tex]((6.91 × [tex]10^{1}[/tex]) + 2.4)

= [tex]10^{-3}[/tex](69.1 + 2.4)

= 71.5 × [tex]10^{-3}[/tex] = 7.15 × [tex]10^{1}[/tex] × [tex]10^{-3}[/tex] = 7.15 × [tex]10^{-2}[/tex]

(c)

[tex]10^{5}[/tex]((9.7 × [tex]10^{1}[/tex]) + 8.3)

= [tex]10^{5}[/tex](97 + 8.3)

= 105.3 × [tex]10^{5}[/tex] = 1.053 × [tex]10^{2}[/tex] × [tex]10^{5}[/tex] = 1.053 × [tex]10^{7}[/tex]

(d)

[tex]10^{1}[/tex]((3.67 × [tex]10^{1}[/tex]) - 1.6)

= [tex]10^{1}[/tex](36.7 - 1.6)

= 35.1 × [tex]10^{1}[/tex] = 3.51 × [tex]10^{1}[/tex] × [tex]10^{1}[/tex] = 3.51 × [tex]10^{2}[/tex]

(e)

[tex]10^{-6}[/tex]((8.41 × [tex]10^{1}[/tex]) - 7.9)

= [tex]10^{-6}[/tex](84.1 - 7.9 )

(f)

[tex]10^{4}[/tex]((1.33 × [tex]10^{1}[/tex]) - 4.9 )

Given rational expression is

[tex]-\frac{8x}{8x^2+2x}[/tex]

Now we need to find the restricted values if any for this rational expression.

Restricted values means the possible values of the used variable (x) that will make denominator 0 as division by 0 is not defined.

So to find the restricted values, we just set denominator equal to 0 and solve for x

[tex]8x^2+2x=0[/tex]

[tex]2x(4x+1)=0[/tex]

2x=0 or 4x+1=0

x=0 or 4x=-1

x=0 or x=-1/4

Hence final answer is x=0, -1/4

To find the restricted values of a rational expression, set the denominator equal to zero and solve for x.

To find the restricted values of the rational expression, we need to determine the values of x that will make the denominator of the expression equal to zero. When the denominator is zero, the expression is undefined.

In this case, the denominator is 8x2 + 2x. We set this equal to zero and solve for x:

8x2 + 2x = 0

Factor out 2x:

2x(4x + 1) = 0

Set each factor equal to zero:

2x = 0, 4x + 1 = 0

Solve each equation:

x = 0, x = -1/4

Therefore, the restricted values of x for the given rational expression are 0 and -1/4.

units.  Is that a perfect length?  I don't know, but I know it's perfect for a square whose area is 45.

To solve a function like this, simply put the numerical value in place of the unknown variable for which you have to find the solution, for instance '-3' in this case.

g(x) = 2x-2

so to find g(-3), we just need to replace the x in the given expression by '-3'. Working is shown below:

g(x) = 2x-2

putting '-3' in place of x

g(-3) = 2(-3) - 2

g(-3) = -6 -2

g(-3) = -8

24 rows of seats

let n be the number of rows

then the number of seats per row = n + 4

number of seats = number of rows × number of seats per row

n(n + 4 ) = 672

n² + 4n - 672 = 0 ← in standard form

the factors of - 672 which sum to + 4 are + 28 and - 24

(n + 28)(n - 24) = 0

equate each factor to zero and solve for n

n + 28 = 0 ⇒ n = - 28

n - 24 = 0 ⇒ n = 24

number of rows n > 0

number of rows = 24 and number of seats per row = 28

24 × 28 = 672 as a check

Answer:

What does the multiplication property of equality allow us to do while solving equations?

C. The multiplication property of equality allows us to multiply both sides of the equation by the same value to maintain equivalent equations.

~batmans wife dun dun dun...

The multiplication property of equality in Mathematics allows us to multiply both sides of an equation by the same value without affecting the equality. This property is useful for simplifying equations and finding unknown variables.

The multiplication property of equality is a crucial concept in solving equations. It states that if you have an equation, you can multiply the same quantity to both sides of the equation without affecting the equality. Essentially, what it says is captured in option C: The multiplication property of equality allows us to multiply both sides of the equation by the same value to maintain equivalent equations.

For example, if we have an equation 2x = 8, we can apply the multiplication property of equality by multiplying both sides of the equation by 1/2 (the reciprocal of 2) to find the value of x, without changing the balance of the equation. So, 2x * 1/2 equals 8 * 1/2, simplified gives us x = 4. This helps in simplifying complex equations and reaching the solution.

Answer: 9x - y = -7

Step-by-step explanation:

Ax + By = C

9x + 7 = y

9x + 7 - y = 0

9x - y = -7

Hope this helps! :)

9x - y = - 7

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

rearrange y = 9x + 7 into this form ( subtract y from both sides )

0 = 9x - y + 7 ( subtract 7 from both sides )

9x - y = - 7 ← in standard form

Answer:

y = 2.5(x + 2)^2 - 3

The answer is A

Step-by-step explanation:

The general equation for the vertex is

y  =  a (x + b)^2 + c

a we are not certain about

b = 2

c = - 3

y = a(x + 2)^2 - 3 Now we have to solve for a.

a is found by using the one point we know (0,7) It means when x = 0 y = 7 so just put those two numbers in.

7 = a(0 - 2)^2 - 3

7 = a (- 2)^2 - 3       Add 3 to both sides.

7 + 3 = a(4)              Combine 7 and 3

10 = 4a                     Divide by 4

10/4 = a                    Do the actual division    

2.5 = a

Answer: See above

A

the equation of a parabola in vertex form is

y = a(x - h )² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here the vertex = (- 2, - 3 ), thus

y = a(x + 2 )² - 3

to find a substitute (0, 7 ) into the equation

7 = 4a - 3 ( add 3 to both sides )

10 = 4a ( divide both sides by 4 )

a = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]

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

- 28[tex]p^{5}[/tex] - 7[tex]p^{4}[/tex] + 7p³

= - 28[tex]p^{5}[/tex] - 7[tex]p^{4}[/tex] + 7p³

Rewrite the equation so both sides have the same base, then equate exponents and solve for c.
