A park shaped like a rectangle. The diagram shows the how the park is split into a sports field and a playground. Let x represent the length in meters of the sports field. Write an expression to represent the area of the park as the sum of the areas of the sports field and the playground.

Answers

Answer:

20r + 310

Step-by-step explanation

For the first part.

The required expression is 20x + 310 which represents the area of the park as the sum of the areas of the sports field and the playground.

What is the expression?

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Let x represent the length in meters of the sports field.

Here, the area of the sports field = 20 × x = 20x units

And, the area of the playground = 15.5 × 20 = 310 units

Now, the required expression to represent the area of the park will be :

⇒ area of the sports field + area of the playground

⇒ 20x + 310

Thus, the required expression is 20x + 310.

Some algae contains up to 50% oil by weight. How much oil is in a 7.3-ounce sample of this type of algae?

This would help if you could solve anyone.

Answers

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

[tex]\frac{1}{2}[/tex] of 7.30 = [tex]3.65[/tex]

Jan tossed a coin 50 times and got a head 20 times. What is the

Answers

Answer:

The standard answer for this is 50%.  

Step-by-step explanation:

  However, this is based on the implicit assumption that the coin is fair.

 

If there are reasonable grounds to doubt that the coin is fair, the theoretical probability must be based on observed statistics.   In this scenario, the probability is 60%.  

Help me with this please it says how can you isolate the term f/3 in f/3 + 22 = 17

Answers

Answer:

Given:

[tex]\sf {\dfrac {f}{3}}+22=17 [/tex]

To find:-

[tex]\sf {\dfrac {f}{3}}[/tex]

Solution:-First write the equation

[tex]{:}\dashrightarrow[/tex][tex]\sf {\dfrac {f}{3}}+22=17 [/tex]

Now take 22 to the other side by which the "+"sign will turn "-".

[tex]{:}\dashrightarrow[/tex][tex]\sf {\dfrac {f}{3}}=17-22 [/tex]

Simplify

[tex]{:}\dashrightarrow[/tex][tex]\sf {\dfrac {f}{3}}=-5 [/tex]

[tex]\therefore[/tex][tex]{\underline{\boxed{\bf {\dfrac {f}{3}}=(-5)}}}[/tex]

Answer: Subtract 22 from both sides.

Step-by-step explanation:

f/3 +22 = 17

f/3 +22 -22 = 17 -22  Subtracting the same value from both sides keeps the equation equal.  

Then simplify. The +22 and -22= 0 They "cancel"   17-22 = -5

f/3 = -17  f/3 is now isolated-- by itself-- in the equation.

If you had to solve for f, the next step would be to multiply both sides by  3.

The given expression 3/4 x 3/4 x 3/4 x 3/4 x 3/4 can be written as (3/4)⁵ in the form of an exponent.

What is the expression?

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

An exponent is a shorthand way of representing a repeated multiplication of the same number.

As per the given question, the number being multiplied is 3/4, and it is being multiplied by itself 5 times. The exponent, 5, tells us how many times the base, 3/4, is being multiplied by itself.

⇒ 3/4 x 3/4 x 3/4 x 3/4 x 3/4

⇒ (3/4)⁵

Therefore, the given expression can be written as (3/4)⁵.

At a local baseball game, the concession stand has two different meal choices. You can get 7 hotdogs and 5
drinks for $41.00 or you can get 4 hotdogs and 8 drinks for $44.00. If the price of hotdogs and drinks is the
same for each meal, find how much it costs for an individual hotdog and how much it costs for an individual
drink.
per hotdog:

per drink:

Answers

Answer:

Each hotdog is $3 and each drink is $4.

Step-by-step explanation:

Let h be the number of hotdogs and d the number of drinks,

7h + 5d = 41

4h + 8d = 44

Let's eliminate h.  Multiply the first by 4 and the second by 7.

28h + 20d = 164

28h + 56d = 308

Subtrat the first from the second.

36d = 144

d = 4

Substitute back into one of the equations.

7h + 5(4) = 41

7h + 20 = 41

7h = 21

h = 3

a. $

Answers

Step-by-step explanation:

A. 36÷3=12 $12 per ticket
