Using the data provided, what percent of the
sampled streams are polluted?

Answer:

q = -1 and p = 3

Step-by-step explanation:

make q the subject of the formula

q = 2p - 7

Let use the other equation to manipulate data

3p + 2q = 7

:3p + 2 (2p - 7) = 7

:3p + 4p - 14 = 7

:3p + 4p = 7 + 14

:7p = 21

7. 7

like terms cancel each other

thus

p = 3

we the first equation to find the value of q

q = 2p - 7

since we have find p as 3, let's substitute

q = 2 (3) - 7

q = 6 - 7

q = -1

Answer:Quotient =3x^2 +8x +4

Remainder=16

Step-by-step explanation:

Inequality is the comparison of mathematical expressions which are not strictly equal. The needed inequality is: 18.45 ≥ 3 + h

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given case, we've got:

Amount spent by Leticia = $18.45

Amount spent by Humberto = h dollars

Since amount spent by Leticia is at least $3. 00 more than what  Humberto spends, thus:

18.45 is at least h + 3 (all in dollars)

(we usually skip stuffs like currency sign or units in equations or inequalities, to keep things as minimized as possible. It is known from the context what unit or currency or such thing is being discussed).

At least can be thought of as equal to that quantity or greater than that quantity but not less than that quantity.

This more than or equal to is written as ≥

Thus, the inequality we get is:

18.45 ≥ 3 + h

13A + 1

Step-by-step explanation:

Combine like terms. Like terms are terms that have the same amount of the same variable:

Set the expression:

12A + A + 2 - 1

(12A + A) + (2 - 1)

13A + 1

13A + 1 is your answer.

~

Hey there!

12a + 2 + a - 1

COMBINE the LIKE TERMS

= (12a + 1a) + (2 - 1)

= 12a + 1a + 2 - 1

= 13a + 1

Therefore, your answer is: 13a + 1

To identify which triangles are congruent measure the angles and sides of each of the triangles and compare them.

In mathematics, the word congruent is used if two figures have the same size and shape, although their orientation can be different.

In the case of triangles two factors should be considered:

This means that to determine if the triangles are congruent, you must measure each side and angle and make sure these are the same in each triangle.

Answer:

d. 1 21/64 inches

Step-by-step explanation:

Add the lengths of the two punches.

4 1/64 + 4 3/32 = 4 1/64 + 4 6/64 = 8 7/64

Subtract the sum from the length of the bar stock.

9 7/16 - 8 7/64 = 9 28/64 - 8 7/64 = 1 21/64

Answer: d. 1 21/64 inches

The 1 15/64  inches of stock are wasted (option c).

To find out how much stock is wasted, we need to subtract the sum of the lengths of the two punches from the original length of the steel bar.

Original length of the steel bar = 9 7/16 inches

Length of the first punch = 4 1/64 inches = 4 + 1/64 inches

Length of the second punch = 4 3/32 inches = 4 + 3/32 inches

Total length of the two punches = (4 + 1/64) + (4 + 3/32) inches

Now, add the lengths of the two punches:

Total length of punches = 8 + 1/64 + 3/32 inches

Convert the fractions to a common denominator (64):

Total length of punches = 8 + 1/64 + 6/64 inches

Total length of punches = 8 + 7/64 inches

Now, subtract the total length of punches from the original length of the steel bar:

Wasted stock = 9 7/16 - (8 + 7/64) inches

Convert 9 7/16 to an improper fraction:

Original length of the steel bar = 9 * 16/16 + 7/16 = 151/16

Now, subtract the total length of punches:

Wasted stock = 151/16 - (8 * 16/16 + 7/64)

Wasted stock = 151/16 - (128/16 + 7/64)

Wasted stock = 151/16 - 130/16 - 7/64

Wasted stock = 21/16 - 7/64

Wasted stock = (21 * 4)/(16 * 4) - 7/64

Wasted stock = 84/64 - 7/64

Wasted stock = 77/64 inches

Now, let's simplify 77/64:

77/64 = 64/64 + 13/64 = 1 + 15/64 inches
