Answer:

$21.25

Step-by-step explanation:

With these type of questions, I make a list on all the values I need to find.

-shoes

-5 bowling games

-2 nachos

-3 large sodas

Since we now have our list, we need to find how much these all cost using the chart.

Shoe rental is $2.75

1 bowling game is $2.5, so 5 of those would be 5 × 2.5, which is $12.5

1 nacho is $1.75, so 2 of those would be 2 × 1.75, which is $3.5

1 large soda is $1.5, so 3 of those would be 3 × 1.5, which is $4.5

Now, I would add these up, BUT, Jason has a coupon that takes 25% off all drinks and food.

So, we add the values of the food up, which is $3.5 + $4.5, which is $8.

25% is the same value as 1/4.

So, split 8 into 4 equal parts, which is 4 groups of 2. Take one out, (because we are taking away 25%), you are left with 8-2, which is 6.

Now, we have all our final values:

$2.75 + $12.5 + $6

If we add all those up, we will get $21.25

Therefore, Jason spent <u>$21.25</u> on bowling

After being dropped a certain ball always bounces back to 2/5 of the height of its previous bounceAfter the first bounce it reac
kap26 [50]

Answer:

8 inches.

Step-by-step explanation:

In the first bounce, the height that the ball reaches was 125 inches.

If the ball always bounces back to \frac{2}{5} of the height, then after 2nd bounce it will reach (125 \times \frac{2}{5}) = 50 inches height.

Again, after 3rd bounce, it will reach (50 \times \frac{2}{5}) = 20 inches height.

And, after 4th bounce, it will reach (20 \times \frac{2}{5}) = 8 inches height. (Answer)

Plss answer!! <br>MERRY Christmas!!! <br>Critical Question. AAAAA​
liberstina [14]

Answer:

Step-by-step explanation:

abc = 1

We have to prove that,

\frac{1}{1+a+b^{-1}}+\frac{1}{1+b+c^{-1}}+\frac{1}{1+c+a^{-1}}=1

We take left hand side of the given equation and solve it,

\frac{1}{1+a+\frac{1}{b}}+\frac{1}{1+b+\frac{1}{c}}+\frac{1}{1+c+\frac{1}{a}}

Since, abc = 1,

\frac{1}{c}=ab and c = \frac{1}{ab}

By substituting these values in the expression,

\frac{1}{1+a+\frac{1}{b}}+\frac{1}{1+b+\frac{1}{c}}+\frac{1}{1+c+\frac{1}{a}}=\frac{1}{1+a+\frac{1}{b}}+\frac{1}{1+b+ab}+\frac{1}{1+\frac{1}{ab}+\frac{1}{a}}

                                       =\frac{b}{b+ab+1}+\frac{1}{1+b+ab}+\frac{ab}{ab+1+b}

                                       =\frac{1+b+ab}{1+b+ab}

                                       =1

Which equal to the right hand side of the equation.

Hence, \frac{1}{1+a+b^{-1}}+\frac{1}{1+b+c^{-1}}+\frac{1}{1+c+a^{-1}}=1

X=7^y how can you rewrite this equation in y = form ?
Anuta_ua [19.1K]

Answer:

y = lnx / ln 7.

Step-by-step explanation:

x = 7^y

Take logarithms of both sides:

ln x = ln 7^y

ln x = y ln 7     ( because ln a^b = b ln a.   One of the Laws of Logarithms).

y = lnx / ln 7.

What is an equation of the line that passes through the points <br> (8,2) and <br> (7,1)?
gogolik [260]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===
