Answer:

35 games.

Step-by-step explanation:

5 out of 8 is 5/8 of their  games which they have won.

So they should win (5/8) * 56

= 5*56 / 8

= 5*7

= 35 games.

Given the Rangers' current win rate of 5 wins out of 8 games, we can predict they would win about 35 games out of 56 if they continue at this rate.

The question you've asked is related to

ratios

and

proportions

. You're given that the Rangers won 5 out of 8 games. If we extend this winning rate to 56 games, we need to find a proportion that equals the same win rate. The setup is: 5/8 = x/56, where 'x' is the number of games we expect the Rangers to win. To solve for x, we multiply across the diagonal (5*56) and divide by 8. That results in a value of

35

, so the Rangers should win 35 games out of 56 if they continue their current winning rate.

Answer:

The equation is:

[tex]y=2500t+75000[/tex] where t is the number of years satisfying the inequality [tex]0\let\le5[/tex] and y is the population at that time.

Step-by-step explanation:

So it gives us the initial amount 75000; this is what happens at time 0.

So we have the point (0,75000) is on the function's graph.

(0,75000)

(1,77500)  -> It goes 2500 per year. So year 1 the population is 75000+2500.

So we have the y-intercept of the line which is (0,75000).

We just need the slope.

Our goal is to put into slope-intercept form: y=mt+b form where m is the slope and b is the y-intercept.

To find the slope, you line up the points vertically and subtract then put 2nd difference over 1st difference.

(  1   ,   77500 )

-( 0  ,    75000)

------------------------

 1           2500

So the slope is 2500/1=2500 which we should have known earlier since the y's are increasing by 2500 while the x's are increasing by 1.

So while t is between 0 and 5 inclusive we have the following equation:

y=2500t+75000

Answer:

Part 1) The area of the structure is [tex]2,453.25\ ft^{2}[/tex]

Part 2) The slab will contain  [tex]1,226.625\ ft^{3}[/tex] of cement

Step-by-step explanation:

Part 1) Find the area of the structure

we know that

The area of the structure is equal to the area of rectangle plus the area of semicircle

Find the area of rectangle

The area of rectangle is equal to

[tex]A=LW[/tex]

we have

[tex]L=70\ ft[/tex]

[tex]W=30\ ft[/tex]

substitute

[tex]A=(70)(30)[/tex]

[tex]A=2,100\ ft^{2}[/tex]

Find the area of semicircle

The area of semicircle is

[tex]A=\frac{1}{2}\pi r^{2}[/tex]

we have

[tex]\pi =3.14[/tex]

[tex]r=15\ ft[/tex]

substitute

[tex]A=\frac{1}{2}(3.14)(15)^{2}[/tex]

[tex]A=353.25\ ft^{2}[/tex]

Find the area of the structure

Adds the areas

[tex]A=2,100+353.25=2,453.25\ ft^{2}[/tex]

Part 2) If the structure is 6 in thick, how many cubic feet of cement will the slab contain?

Remember that

[tex]1\ foot=12\ inches[/tex]

Convert inches to feet

[tex]6\ in=6/12=0.5\ ft[/tex]

Find the volume of the structure

To obtain the volume , multiply the area by 0.5 ft (thick)

so

[tex]V=2,453.25*0.5=1,226.625\ ft^{3}[/tex]

To prove congruence through ASA, we need the measures of two angles that are adjacent to a given side. If we are given that two angles are congruent to other angles in another triangle respectively and both of those angles are adjacent to one side (in which each side of each triangle is congruent) then the triangles are congruent through ASA.

To prove congruence using the ASA congruence theorem, we need to show that the angle measures of the triangles are equal. The additional information needed is that angle NM is congruent.

Step-by-step explanation:

We know the formula for area of a square is

A = s^2 where s is the side length

49 = s^2

Take the square root of each side

sqrt(49) = sqrt(s^2)

7 =s

The side length is 7 yds

Final answer:

To find the side length of a square given its area, calculate the square root of the area. In this case, the side length of the square is 7 yards.

Explanation:

A square has an area of 49yd². To find the side length of each side, you need to take the square root of the area. In this case, the side length of each side would be 7 yards.

Answer:

y = [tex]\frac{30-3x}{5}[/tex]

Step-by-step explanation:

Given

3x + 5y = 30

Isolate the term in y by subtracting 3x from both sides

5y = 30 - 3x ( divide both sides by 5 )

y = [tex]\frac{30-3x}{5}[/tex]

Answer:

[tex]y=\frac{-3}{5}x+6[/tex]

Step-by-step explanation:

3x+5y=30 is the given equation.

We are asked to isolate y.

The term that contains y is 5y. I'm going to first isolate 5y.

To isolate 5y we see that we have +3x with it.  To undo addition of 3x we will need to subtract 3x on both sides.

3x+5y=30

-3x          -3x

     5y=-3x+30

We now have 5y by itself.  There is actually one step left to get the y by itself.

The last step is undo this multiplication between 5 and y.

To undo multiplication you divide.

So we will be dividing 5 on both sides. This gives us:

3x+5y=30

-3x        -3x

     5y=-3x+30

     --     ---------

     5          5

So the whole reason we did that is because 5y/5 is just y.  I'm going to separate that fraction on the right hand side.  This gives me:

     y=-3/5  x   +  30/5

I'm going to simplify the 30/5 to 6.

    y=-3/5   x          +6

Answer:

The  number of years = 3 years

Step-by-step explanation:

Points to remember

Simple interest

I = PNR/100

Where P - Principle amount

N - Number of years

R - Rate of interest

To find the number of years

Here P = 25,000

R = 3.5% and I = 2625

I = PNR/100

N = (I * 100)/PR

 = (2625 * 100)/(25000 * 3.5)

 = 3 years

Therefore number of years = 3 years

Answer:

The equation would be x²/a² - y²/b² =1 , x²/9 - y²/40 = 1 ....

Step-by-step explanation:

The standard equation of hyperbola with a horizontal transverse axis is:

(x-h)²/a² - (y-k)² /b²  = 1

Use Pythagorean theorem to find the value of b.

c² = a²+b²

c= 7

a = 3

Put the value in the equation:

(7)² = (3)² +b²

49= 9+b²

49-9 = b²

40 = b²

Square root both sides:

√40 = √b²

√40 = b

Assume that the center of hyperbola is(0,0)

Thus

(x-0)²/a²  - (y-0)²/b² = 1

x²/a² - y²/b² =1

x²/(3)² - y²/(√40)² = 1

x²/9 - y²/40 = 1

Therefore the equation would be x²/a² - y²/b² =1 , x²/9 - y²/40 = 1 ....

Answer:

[tex]\dfrac{x^{2}}{9} - \dfrac{y^{2}}{40}} = 1[/tex]

Step-by-step explanation:

The standard form of the equation of a hyperbola with center (0,0) and horizontal transverse axis is

[tex]\dfrac{x^{2}}{a^{2}} - \dfrac{y^{2}}{b^{2}} = 1[/tex]

and the distance c between the foci and the y-axis is given by

c² = a² + b²

1. Calculate b

7² = 3² + b²

49 = 9 + b²

40 = b²

b = √40

2. Write the equation

[tex]\dfrac{x^{2}}{3^{2}} - \dfrac{y^{2}}{(\sqrt{40})^{2}} = 1\\\\\mathbf{\dfrac{x^{2}}{9} - \dfrac{y^{2}}{40}}} = \mathbf{1}[/tex]

The figure shows your hyperbola with a horizontal transverse axis and c = 3.

Answer:

352.8 feet

Step-by-step explanation:

The given triangle is drawn in the image attached with. Note that the image is not drawn to scale.

We can find the length of AB using the law of sines. According to which:

[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]

Since sum of angles in a triangle is 180, we can write:

A + B + C = 180

A + 102.9 + 18.6 = 180

A = 58.5

Using the values, in the law of sines, we get:

[tex]\frac{943}{sin(58.5)} = \frac{c}{sin(18.6)}\\\\ c = \frac{943 \times sin(18.6)}{sin(58.5)}\\\\ c = 352.8[/tex]

Thus, the measure of side AB would be 352.8 feet

Answer:

The length of AB is 352.8 feet

Step-by-step explanation:

* Lets revise some facts to solve the problem

- The sine rule: [tex]\frac{sinA}{BC}=\frac{sinB}{AC}=\frac{sinC}{AB}[/tex]

- The sum of the measures of the interior angles of a triangle is 180°

* Lets solve the problem

- In Δ ABC

∵ m∠ B = 102.9°

∵ m∠ C = 18.6°

∵ m ∠A + m∠ B + m∠ C = 180° ⇒ interior angles of a Δ

∴ m ∠A + 102.9 + 18.6 = 180

∴ m ∠A + 121.5 = 180 ⇒ subtract 121.5 from both sides

∴ m∠A = 58.5°

* Lets use the sine rule to find AB

∵ BC = 943

∵ m∠A = 58.5°

∵ m∠ C = 18.6°

∴ [tex]\frac{sin(58.5)}{943}=\frac{sin(18.6)}{AB}[/tex]

- By using cross multiplication

∴ AB × sin(58.5) = 943 × sin(18.6)

- Divide both sides by sin(58.5)

∴ AB = [943 × sin(18.6)] ÷ sin(58.5) = 352.76 ≅ 352.8

* The length of AB is 352.8 feet

Step-by-step explanation:

1. We must first subtract the base area of the pyramid from the total surface area to get the lateral surface area:

[tex]LA=2225-25^2=1600[/tex]

The lateral surface area is 4 times the area of one the congruent triangles.

[tex]LA=4\cdot \frac{1}{2}\cdot 25\cdot x[/tex]

[tex]\implies 1600=50x[/tex]

[tex]\implies \frac{1600}{50}=\frac{50x}{50}[/tex]

[tex]32=x[/tex]

Therefore the height of the slant surface is 32 yards

2) The surface area of a cone is [tex]S.A =\pi r^2+\pi r l[/tex], where l is the slant height.

We substitute the surface area S.A=151.58 and [tex]\pi=3.14,r=4[/tex] to obtain:

[tex]151.58=3.14\cdot 4^2+3.14\cdot 4 l[/tex]

[tex]151.58=50.24+12.56l[/tex]

[tex]101.34=12.56l[/tex]
