Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen ions. If a substance has a pH of 6, which equation could be used to find its H value?

Answers

Answer 1

Answer:

[H^+] = Antilog[-6]

Step-by-step explanation:

Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.

pH=−log[logH^+]

-pH = log[H^+]

[H^+] = Antilog[-pH]

Since pH =6

The equation is;

[H^+] = Antilog[-6]

Answer 2

Answer:

logH=−6

Step-by-step explanation:

Substituting the given value into the formula: 6=−logH; −6=logH; 10−6=H; H=0.000001. The equation logH=−6 is a step in the process of finding the H value.

Im checking my answers for this question and im wondering if im correct or not

Answers

Answer and step-by-step explanation:

Checking what you've done, the first two images you've shown have the correct matching. But the last two are wrong. Reason being:

For the third mage, the table suggests that all the points are on the positive part of the y-axis, this means the curve should open upwards not downwards.

For the last image, the table suggests that the points are on the negative part of the y–axis except (0, 1). This means the curve should open downwards not upwards.

The table in the third image should match the graph in the last image and the table in the last image should match the graph in the third image.

How do you recognize if a binomial is a difference of perfect squares and how is the pattern used to factor the binomial?

Answers

Answer:

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

Step-by-step explanation:

A binomial is an expression with only terms where at least one is a term with a variable. When we can factor for difference of squares, we can have two variable terms or just one with a constant.

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

The manager of a grocery store estimates that 74% of customers will make a purchase. Part A: How many customers should a cashier expect until he finds a customer that makes a purchase?
Part B: What is the probability that a cashier helps 3 customers until he finds the first person to make a purchase?

Answers

Answer:

a. The number of customers that should a cashier expected till to find a customer is 1.35

b. The probability for helping three customers is 0.013

Step-by-step explanation:

The computation is shown below:

A. The number of customers that should a cashier expected till to find a customer is as follows:

= 1 ÷ 0.74

= 1.35

b. The probability for helping three customers is

= (1 - 0.74)^3 × 0.74

= 0.013

Maggie buys a dress and a pair of shoes at The Home Store. Before adding the sales tax, she pays $48 for a dress that normally sells for $62 and she pays $34 for a pair of shoes that normally sells for $46. a) Before the sales tax, how much does Maggie save on her purchases by buying at the sale price? Show all work. b) To the nearest percent, what percent discount did Maggie get on her total purchase? Show all work. c) Including a 15% sales tax, what total amount will Maggie pay?

Answers

Answer:

a) $26

b) 24.07%

c) $94.3

Step-by-step explanation:

Given that:

Before tax:

Normal price of dress = $62

Discounted price of dress = $48

Normal price of a pair of shoes = $46

Discounted price of a pair of shoes = $34

a) Before the sales tax, total savings = ($64 - $48) + ($46 - $34) = $26

b) Total percentage discount on total sales.

Total bill for original price = $62 + $46 = $108

Percentage discount can be found by the formula:

[tex]\dfrac{\text{Total discount}}{\text{Total bill for original price}}\times 100\\\Rightarrow \dfrac{26}{108} \times 100 = 24.07\%[/tex]

c) Total amount paid if the sales tax is 15%.

Amount paid with tax = Amount after discount + 15% of amount after discount

Amount after discount = $48 + $34 = $82

15% of $82 = $18.29

Amount paid with sales tax = $82 + $12.3 = $94.3

And these two are co - interior angles . And sum of co - interior angles is 180°.

Hence , here

[tex]\tt:\implies \angle DCB + \angle ABC = 180^{\circ} \\\\\tt:\implies (2x + 12)^{\circ} + 5x^{\circ}=180^{\circ} \\\\\tt:\implies 7x = (180 - 12 )^{\circ} \\\\\tt:\implies 7x = 168^{\circ} \\\\\tt:\implies x =\dfrac{168^{\circ}}{7} \\\\\underline{\boxed{\red{\tt\longmapsto x = 24^{\circ}}}}[/tex]

Peter and Angad win some money and share it in the ratio 4:1. Peter gets £28. How much did they win in total

Answers

Answer:

£35

Step-by-step explanation:

The ratio is 4:1.

Since we know that Peter gets £28, we can divide that 28 by 4 to get Angad's share:

28/4 = 7

This means Angad got £7.

Now we add these 2 amounts together to find the total:

£28 + £7 = £35

Therefore, they won a total of £35.

Four copies of the triangle shown are joined together, without gaps or overlaps, to make a parallelogram. measurements= 5cm, 13cm, 12cm What is the largest possible perimeter of the parallelogram?

Answers

Answer:

Highest Possible Perimeter = 52cm

Step-by-step explanation:

The triangle is not shown. But, the question can still be solved.

The given sides (5cm,12cm and 13cm) of the triangle shows that the triangle is a right angled triangle as proven below:.

[tex]13\² = 5\² + 12\²[/tex]

[tex]169 = 25 + 144[/tex]

[tex]169 = 169[/tex]

Having shown that;

The next step is to determine the highest possible value of the perimeter.

To get the highest possible perimeter;

The 4 triangles have to be joined at the 12cm and 5cm part of each triangle (see attachment).

From the attachment, the perimeter is then calculated as:

Perimeter = 13cm + 13cm + 13cm+ 13cm

Perimeter = 52 cm
