The pH scale measures how acidic or basic a substance is. Lemon juice is said to have a pH of less than 4 and greater than 1.5. Model the normal range of pH values of lemon juice, using a compound inequality.

Answer:

Step-by-step explanation:

18+(-4)= 18 - 4 = 14

-5 + (-18) = - 5 - 18 = - 23  

9 + (-18) = 9 - 18 = - 9  

-18 + 18 = 0

Use exponent rule: x^y * x^z = x^y+z

4^2 * 4^8

4^2+8

4^10

1,048,576

Best of Luck!

5. Body composition

Step-by-step explanation:

5y - 16 + 3y + 20 = 180 degrees

Combine like terms on the left side

8y + 4 = 180

Subtract 4 from both sides.

8y = 176

Divide both sides by 8

y = 22

Plug 22 into y for each angle.

3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees

5y - 16 = 5(22) - 16 = 110 - 16 = 94

The angle opposite 5y - 16 also equals 94 because they are vertical angles.

The angle opposite of 3y + 20 also equals 86 because they are vertical angles

Answer:

C. An = 5(2)^n-1

Step-by-step explanation:

Tower 1 2 3 4 5

Number of blocks 5 10 20 40 80

Where,

n = tower number

An = number of blocks

A. an = n + 80

B. an = 2n + 5

C. An = 5(2)^n-1

D. an = 10(5)^n

Checking all options

A. An = n + 80

When n = 1

An = 1 + 80

= 81

B. An = 2n + 5

When n = 1

= 2(1) + 5

= 2 + 5

= 7

C. An = 5(2)^n-1

When n = 1

= 5(2)^1-1

= 5(2)^0

2^0 = 1

= 5(1)

= 5

D. An = 10(5)^n

When n = 1

= 10(5)^1

5^1 = 5

= 10(5)

= 50

The explicit formula which correctly represents the number of blocks, an, in terms of the tower number, n is C. An = 5(2)^n-1

Answer:

  $64.75

Step-by-step explanation:

You can add $12.95 five times:

  $12.95 +12.95 +12.95 +12.95 +12.95 = spending

but it is probably easier to use multiplication:

  5 × $12.95 = spending = $64.75

Adam spent $64.75.

Answer:

64.75

Step-by-step explanation:

So you have 5 DVDs bought and 12.95 for each.

12.95 x 5

12.95 + 12.95 = 25.90

25.90 + 12.95 = 38.85

38.85 + 12.95 = 51.80

51.80 + 12.95 = 64.75

So your answer is $64.75

Answer:

Step-by-step explanation:

Answer:

A) 1,492

B) 1,908

Step-by-step explanation:

A) The equation set up for this part is 1,542-50=1,492 We know that we're subtracting 50 from 1,542 because it say that the plane starts below sea level.

B) The equation set up for this part is 3,400-1,492=1,908 We know that we're subtracting the answer from part A from 3,400 because the plane will need to climb the difference in order to reach 3,400.

Answer: 1.23×10¹⁶

Step-by-step explanation:

For this problem, we want to use order of operations to solve.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Let's first solve the parenthesis.

[tex](9*\frac{999999999}{9+9+9+9+9+9+9+9+9} )^2[/tex]                [add denominator]

[tex](9*\frac{999999999}{81} )^2[/tex]                                  [cross multiply]

[tex](\frac{999999999}{9} )^2[/tex]                                       [divide]

[tex](111111111)^2[/tex]                                     [exponent]

1.23×10¹⁶

The ending result is way too large. Therefore, we use scientific notation and get 1.23×10¹⁶.
