Hey there! :)

Answer:

24 pages.

Step-by-step explanation:

Calculate how many pages 75% of 96 is:

96 × 0.75 = 72 pages.

Find how many pages do not have ads by subtracting the amount that have ads from the total:

96 - 72 = 24 pages.

Therefore, 1/4 of 96 or 24 pages do not have ads.

Answer:

39.8°

Step-by-step explanation:

We know slope is rise over run. That would mean our right triangle would have a horizontal leg of 6 and a vertical leg of 5. From there we use tan∅ to help solve ∅:

tan∅ = 5/6

∅ = tan⁻¹(5/6)

∅ = 39.8056

Answer:

You have to multiply all the sides by 4.

B to C = 2.8*4

2.8 * 4 = 11.2

B to A = 3*4

3*4 = 12

A to C = 2.2*4  

2.2*4 = 8.8

Answer:

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

slope-intercept form: y=[tex]-\frac{3}{5}[/tex]x+[tex]\frac{9}{5}[/tex]

Step-by-step explanation:

so to find point-slope form, you first have to find the slope of the line

--slope =[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]=[tex]\frac{0-3}{3+2} =-\frac{3}{5}[/tex] (you have to use the two points shown: (-2,3) and (3,0) to plug in for y1, y2, x1, and x2 to find the slope.)

so your slope is [tex]-\frac{3}{5}[/tex].

Now all you have to do is use one of the points (-2,3) to sub in for y1 and x1 in the point-slope form equation.

Therefore, you get y-3=[tex]-\frac{3}{5}[/tex](x+2) for point-slope form.

Now for slope-intercept form, you already have the slope because you found it to complete the equation for point slope form

slope = [tex]-\frac{3}{5}[/tex]

Now slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.

So, far we have y=[tex]-\frac{3}{5}[/tex]x+b

the easiet point to use for the x and y values is (3,0)

so, lets substitute: 0=[tex]-\frac{3}{5}[/tex](3)+b, which becomes 0=[tex]-\frac{9}{5}[/tex]+b

add [tex]-\frac{9}{5}[/tex] to both sides to get b=[tex]\frac{9}{5}[/tex]

Now you have both the slope and the y-intercept so you can now write the line in slope-intercept form.

You get [tex]y=-\frac{3}{5}x +\frac{9}{5}[/tex].

Answer:

30 persons

Step-by-step explanation:

Let's create a proportion using the following setup:

persons/rice=persons/rice

We know that 12 persons can eat 8 kilograms of fried rice.

12 persons/ 8 kg of rice= persons/rice

We also know that x (unknown) persons can eat 20 kilograms of fried rice.

12 persons/ 8 kg of rice= x persons/ 20 kg of rice

12/8=x/20

x is being divided by 20. The inverse of division is multiplication. Multiply both sides of the equation by 20.

20(12/8)=(x/20)20

20*12/8=x

20*1.5=x

30=x

30 persons can eat 20 kilograms of fried rice.

Answer:

30 people

Step-by-step explanation:

1) Set up a proportion, 8kg/12 = 20kg/x

2) Do cross multiplication to solve for x

3) x = 30 people

Answer:

x² - 2x - 8

Step-by-step explanation:

Algebra tiles are tiles used to represent variables or numbers and are rectangular or square shaped.

1 is labeled + x squared, this gives x²

2 are labeled + x, this gives +x × 2 = +2x

4 tiles below + x squared are labeled negative x, this gives - x × 4 = - 4x

8 tiles below the + x tiles are labeled negative, this gives -1 × 8 = -8

Therefore to get the polynomial that was factored, we add all the terms. This gives :

+x² + (+ 2x) + (-4x) + (-8) = x² + 2x - 4x - 8 = x² - 2x - 8

Answer: 23 years.

Step-by-step explanation: The labor productivity grows 3% per year, then the rate of growing is 1 + 0.03 = 1.03.

The equation to caclulate the years is:

[tex]y = y_{0}.(1.03)^{t}[/tex]

To double: [tex]y = 2y_{0}[/tex]

Substituing:

[tex]2y_{0} = y_{0}.(1.03)^{t}\\(1.03)^{t} = 2\\ln1.03^{t} = ln2\\t = \frac{ln2}{ln1.03}\\ t = 23[/tex]

To double the standard of living, it will take 23 years.

Answer:

29 square yards

Step-by-step explanation:

see attachment for the graph

Vertices of rectangular pool are A(3,2),B(7,8),C (4,10), and D (0,4).

AB=[tex]\sqrt{(7-3)^{2}+(8-2)^{2}}= \sqrt{16+36}=\sqrt{52}[/tex] yard=CD

BC= [tex]\sqrt{(7-4)^{2}+(8-10)^{2}}=\sqrt{9+4}=\sqrt{13}[/tex]yard=DA

In order to find the area of rectangular pool =Length × Breadth

                                        =√52 ×√13=13×2=26 sq. yard

Vertices of triangle given are: P(5,2),Q(7,2) and R(7,5).

PQ= 2 units, QR= 3 units

Area of right triangle PQR=1/2 ×PQ×PR

                                           =1/2×2×3= 3 sq. yards

Next is to find total material needed to cover( that includes bot rectangular pool and triangular hot tub)

       = Area of rectangle + Area of right triangle

Answer:

B. 10 minutes

Step-by-step explanation:

Let x represent the number of minutes that a sea otter can hold its breath. A hippopotamus can hold its breath for 5 minutes longer than x. So, the equation would be:

x + 5 = 15

Subtract 5 from both sides.

x + 5 = 15

x + 5 - 5 = 15 - 5

x = 10

A sea otter can hold its breath for 10 minutes.

Answer:

equilateral triangle ANP inscribed in circle C

regular hexagon AMNBPQ inscribed in circle C

Step-by-step explanation:

By looking through our choices, we can eliminate which choices could be wrong and which choices could be right.

Δ MNQ does form a triangle, however, it DOES NOT form a equilateral triangle.

Δ ANP does form a triangle and it is ALSO an equilateral triangle.

Hexagon AMNBPQ does form a hexagon and it is ALSO a regular polygon as we can see all the sides and angles within the polygon are congruent to one another.

MNPQ does form a quadrilateral, however, it DOES NOT form a square. It is instead a rectangle.

ANBQ does form a quadrilateral, however, it DOES NOT form a square. It is instead a rectangle.

By looking through our observations, we can conclude that Δ ANP and hexagon AMNBPQ are the correct choices.

Answer:

It will take 4.84 hours for the drug to decay to 93​% of the original​ dosage.

Step-by-step explanation:

We are given that the half-life of a certain tranquilizer in the bloodstream is 47 hours.

The given exponential model is: [tex]A = A_0 e^{kt}[/tex]

Now, we know that A becomes half after 47 hours which means that;

[tex]A = 0.5 A_0[/tex]

Using this in the above equation we get;

[tex]A = A_0 e^{kt}[/tex]

[tex]0.5 A_0 = A_0 e^{(k\times 47)}[/tex]  where t = 47 hours

[tex]\frac{0.5 A_0}{A_0} = e^{(47k)}[/tex]

[tex]0.5 = e^{47k}[/tex]

Taking log on both sides we get;

[tex]ln(0.5) = ln(e^{47k})[/tex]

[tex]ln(0.5) =47k[/tex]

[tex]k = \frac{ln(0.5)}{47}[/tex]

k = -0.015

Now, the time it will take for the drug to decay to 93​% of the original​ dosage is given by;

[tex]0.93 = e^{kt}[/tex]  where t is the required time

[tex]0.93 = e^{(-0.015 \times t)}[/tex]

Taking log on both sides we get;

[tex]ln(0.93) = ln(e^{-0.015t})[/tex]

[tex]ln(0.93) =-0.015t[/tex]

[tex]t = \frac{ln(0.93)}{-0.015}[/tex]

t = 4.84 hours

Hence, it will take 4.84 hours for the drug to decay to 93​% of the original​ dosage.

Answer:

the first step to eliminate d is to multiply equation B by 5

second :(m,n) (-6,-11)

value of a can be substituted into equation D to solve the system of equations is 7b-1

Step-by-step explanation:

first equation:

4c=d-8 or 4c-d=-8

c=5d+8 or c-5d=8

so the first step to eliminate d is to multiply equation B by 5

second equation :

n=3m+7 or n-3m=7

n-2m=1

n-3m=7

solve :

1-eliminate n by subtracting two equation : : n-2m-(n-3m)=1-7

-2m+3m=-6

m=-6

substitute m: n-3(-6)=7 , then n+18=7

n=7-18=-11

third :

a=3b+6 or a-3b=6

a=7b-1

find a

a-3b=6

value of a can be substituted into equation D to solve the system of equations is 7b-1

Answer:

Step-by-step explanation:

Abigail wants to produce a tapestry that will be in the shape of a parallelogram

The tapestry is 24 inches across the bottom and 36 inches tall

She pieces smaller simlar parallelograms that are 2 inches wide and 3 inches tall

The first step is to find the area of the whole tapestry

Area = base × height

Base= 24 inches

Height= 36 inches

Area= 24×36

= 864 square inches

The next step is calculate the area of the smaller pieces

Area= base × height

Base= 2 inches

Height= 3 inches

Area= 2×3

= 6 square inches

Therefore, the value needed to produce the tapestry can be calculated by dividing the area of the whole tapestry by the area of the smaller pieces

= 864/6

= 144

Hence Abigail will need 144 smaller similar parallelograms to make the tapestry.
