jeremy sells strawberries 5 pounds for $7.50. what is the cost for 1 pound of strawberries?

Answer:

- 11s² + 2s + 9

Step-by-step explanation:

B = 2s + s²

A = 3 - 4s²

then

 2s + s² + 3(3 - 4s²)

=2s + s²+ 9 - 12s²

= - 11s² + 2s + 9

The possible coordinates of the point C are : (-6,-2) and (2,-2).

A stiff transition called a rotation involves turning the item around a center point. The direction is changed, but the shape is still oriented in the same way. You can spin a form in any direction. A 180 degree rotation of the triangle is made around point C. A rigorous transition like this one may be seen here.

Rotation and translation are the only two elements of a rigid transformation. It does not alter the size or shape of an input object, nor does it involve reflection.

Hence as the graph shows, the coordinates of C' could be:

(-6,-2) and (2,-2)

The value of x after solving the expression is 3.

What is an expression?

An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. To assist identify the sequence of operations and other features of logical syntax, mathematical symbols can denote numerals (constants), variable, operations, equations, brackets, punctuation, and grouping. Many writers differentiate between an expression and a formula, with the former referring to a mathematical item and the latter referring to a statement about mathematical things. However, in modern mathematics, and particularly in computer algebra, formulae are considered as expressions that may be evaluated as true or false based on the values assigned to the variables in the expressions.

Given expression 6x-7 = 4x-1

   or, 6x-4x = -1+7

   or, 2x = 6

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ log₅ (1/25)

Now,

Solve the expression as;

⇒ log₅ (1/25)

Since, log (a/b) = log a - log b

Hence,

⇒ log₅ (1/25) = log₅ 1 - log₅ 25

Since, log 1 = 0

⇒ log₅ (1/25) = 0 - log₅ 25

⇒ log₅ (1/25) = - log₅ 5²

Since, log a² = 2 log a

⇒ log₅ (1/25) = - 2 log₅ 5

Since,  log₅ 5 = 1

⇒ log₅ (1/25) = - 2 x 1

⇒ log₅ (1/25) = - 2

Step-by-step explanation:

I assume we want ca miles/hour answer as speed.

but just formally, any distance per time unit is speed.

in that sense

12 miles / 20 minutes = 3 miles / 5 minutes

is the speed.

but now to convert this to miles/hour.

we want to multiply 3/5 or 12/20 by f/f, so that the denominator is 1 hour.

by multiplying the numerator by the same value we make sure the speed ratio remains the same.

so, what "f" do we need to multiply 20 with to get 60 (1 hour = 60 minutes) ?

right, f = 3

therefore, we get

12/20 × 3/3 = (12×3)/(20×3) = 36/60 = 36 miles / 1 hour

You want to know how many adults and children were admitted if there were twice as many children who paid $5.25 for admission as there were adults who paid $7.50, and total admission revenue was $378.

Let 'a' represent the number of adults admitted. Then 2a is the number of children. The total revenue is ...

  7.50a +5.25(2a) = 378

Collecting terms, we have ...

  18a = 378

  a = 21 . . . . . . . divide by 18

  2a = 2·21 = 42 . . . . . find the number of children admitted

21 adults and 42 children were admitted.

21 adults were admitted.

42 children were admitted.

Algebra is one of the numerous subfields of mathematics. The study of mathematical symbols and the rules for employing them in formulas is commonly referred to as algebra, which runs across almost all of mathematics.

Due to that,

Carnival earns a total of $378 in one hour.

Adult fees are $7.50.

Children's fees equal $5.25

Suppose that the carnival allows twice as many youngsters as adults.

If there are x adult, then

Children will thereafter be twice as many.

Since,

$378 is the total amount from both adults and children.

Then,

7.50x + 5.25(2x) = 378

7.50x + 10.50x = 378

18x = 378

x = 378 / 18

x = 21

As x was the total number of adults

Then, in an hour, 21 adults were admitted.

Since there were a total of two children,

Next, there were

42 kids were admitted in an hour (2(21)).

As a result, 42 kids and 21 adults were admitted in one hour.

It was stated that the toy company that makes bubbles fills its 8-ounce bottles using a machine.

The bottle passes inspection if the percent error of the amount is 2% or less. The minimum range will be:

= 8 ounces - (2% × 8 ounces)

= 8 ounces - 0.16 ounces

= 7.84 ounces

The maximum range will be:.

The allowable range for the toy company is [7.84, 8.16].

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, the allowable percentage error is 2% or less.

Now, 2% of 8 ounces is,

= (2/100)×8.

= 0.16 ounces.

So, the allowable range is from (8 - 0.16) = 7.84 ounces to

(8 + 0.16) = 8.16 ounces.

Step-by-step explanation:

the 2 triangles are similar.

that means their corresponding angles are equal, and their side lengths (and heights and so on) have all the same constant scaling factor.

so, we see that the side with the length 6 must corresponds to the side with the length 3 (factor 1/2).

as then the side with the length 5 corresponds to the side with the length 2.5, and the side with the length 4 corresponds to the side with the length 2 (all have the same factor 1/2).

a is the angle between 6 and 5 (the 2 longest sides).

the angle between the 2 longest sides in the smaller triangle (3 and 2.5) is d.

so, a and d correspond.

b is the angle between 6 and 4 (the longest and the shortest side).

the angle between the corresponding sides 3 and 2 is c.

so, b and c correspond.

therefore, the 4th and last answer choice is correct.
