Answer:

x = 15, y = 5

Step-by-step explanation:

total score of A = 6x

total score of B = 25*8 = 200

total score of C = 20y

(6x+200)/(x+25)=7.25

6x+200 = 7.25x+181.25

18.75 = 1.25x

x = 15

and

(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5

plug in x

(290+20y)/60 = 6.5

290 + 20y = 390

20y = 100

y = 5

Answer:

C.

Step-by-step explanation:

When we add up all the numbers we get 111 then we divide it by 10 which gives us 11.1. since we have no value to round to the tenths place, the answer stays the same.

Answer:

$45.05

Step-by-step explanation:

To find 10% divide the original number by 10. This is $5.30

To find 5% divide 10% by 2. This is $2.65

Add the two together to get 15%. This is $7.95

Take away the value of 15% from the original number.

$53.00 - $7.95 = $45.05

Answer:

10

Step-by-step explanation:

Solve f(x)=2, if f(x)=1/2x-3

Both equations are set to equal f(x) so the solution would be the two equations set to equal each other

2 = 1/2x - 3

==> add 3 to both sides

5 = 1/2x

==> multiply both sides by 2

10 = x

Answer:

x = 10

given:

f(x) = 2

======

[tex]\sf \rightarrow \dfrac{1}{2} x- 3= 2[/tex]

change side

[tex]\sf \rightarrow \dfrac{1}{2} x= 2+3[/tex]

simplify the following

[tex]\sf \rightarrow \dfrac{1}{2} x= 5[/tex]

change side

[tex]\sf \rightarrow x= 5*2[/tex]

final outcome

[tex]\sf \rightarrow x= 10[/tex]

Answer:

Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.

Let's solve for h in this problem.  

h = -b/2a

h = -(96) / 2(-16)

h = -96 / -32

h = 3 seconds

Now let's add t=3 to our equation:

y = -16t^2 + 96t + 3

y = -16*(3)^2 + 96*(3)+ 3

y = -144 + 288 + 3

We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.

Answer:

Step-by-step explanation:

Find the height at   h(0)   and   h(1)

h(0) = 3 ft

h(1) = -16 + 32 + 3 = 19 ft

It takes 1 second to go from 3 feet to 19 feet

  (19-3) ft / 1 sec = 16 ft/sec

Answer:

x= −2 and y=2

Step-by-step explanation:

First graph it onto the coordinate plane. Wherever they intersect, those coordinates are the answer.

To graph the equation,

1) Plot the y-intercept

2) Depending on whether the slope is positive or negative, go up or down and left or right from the y-intercept.

The perimeter of the semicircular region is the circumference of the semicircle plus the diameter

                 d: diameter length

                  r: radius length

6. [tex]Perimeter=\frac{1}{2}\pi d + d= \frac{1}{2} \pi *18+18=9\pi +18 = 46.26cm[/tex]

7. [tex]Perimeter =\frac{1}{2}\pi d+d= \frac{1}{2} \pi *20+20 = 31.4+20=51.4 in[/tex]

8. [tex]Perimeter=\pi r+2r = \pi *4 + 8=20.56mm[/tex]

Answer:

miles to travel directly south = 54 miles (to the nearest mile)

extra miles = 68 miles (nearest mile)

Step-by-step explanation:

We need to find the height of the right triangle in the diagram.

To do this, use the sine trig ratio.

[tex]\sin(x)=\sf\dfrac{O}{H}[/tex]

where:

Given:

[tex]x[/tex] = 27°

O = height (h)

H = 120 miles

Substituting the given values into the formula:

[tex]\implies \sin(27^{\circ})=\sf\dfrac{h}{120}[/tex]

[tex]\implies \sf h=120 \sin(27^{\circ})[/tex]

[tex]\implies \sf h=54.47885997...[/tex]

Therefore, the shipmate will have to travel 54 miles (to the nearest mile) directly south.

To find the number of extra miles have been traveled, we first need to find the base length of the right triangle.

To do this, use the cos trig ratio.

[tex]\cos(x)=\sf\dfrac{A}{H}[/tex]

where:

Given:

Substituting the given values into the formula:

[tex]\implies \cos(27^{\circ})=\sf\dfrac{b}{120}[/tex]

[tex]\implies \sf b=120 \cos(27^{\circ})[/tex]

[tex]\sf \implies b=106.9207829...[/tex]

Therefore, the base of the right triangle is 106.9207829... miles

To find the extra miles, sum the hypotenuse and the height of the triangle, then subtract the base.

Extra miles = (120 + 54.47885997... ) - 106.9207829...

                  = 67.55807707...

                  = 68 miles (nearest mile)

Answer:

[tex]Hi!~I~am~beinggreat78,~and~I~will~help~you![/tex]

Let's start by breaking down the problem.

This is how it should look. ↓

[tex]60[/tex] ÷ [tex]20[/tex] ⇒ [tex]+ 3[/tex] ⇒ [tex]x * 5^2[/tex]

What does that x mean? x is just a substituted value for the first 2 equations.

Now, we can solve.

[tex]60[/tex] ÷ [tex]20[/tex] [tex]= 3[/tex]

Add 3

[tex]3 + 3 = 6[/tex]

Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.

[tex]5^2~or~5 * 5 = 25[/tex]

And now for the last step, multiply 25 times 6

[tex]25 * 6 = 150[/tex]

With that information, the problem is solved! Your answer is 150
