Carmen enters a painting in an art contest. The contest rules say that all paintings must be rectangular with an area no greater than 3,003.84 cm2 . Carmen's painting is 16 cm wide.

What is the greatest length the painting can have and still have an area within the contest rules?

Answers

Answer:

[tex]187.74\:\mathrm{cm}[/tex]

Step-by-step explanation:

The area of a rectangle is given by [tex]l\cdot w[/tex]. Therefore, we can set up the following inequality:

[tex]l\cdot 16 \leq 3,003.84[/tex].

Solving this inequality, we have:

[tex]l \leq 187.74[/tex].

Therefore, the largest length Carmen's painting can be is [tex]\fbox{$187.74\:\mathrm{cm}$}[/tex].

Find the missing value of the variable
55°
x + 74
54°

Answers

Answer:

x = -3

Step-by-step explanation:

55 + 54 = 109

109 + 74 = 183

Triangles = 180 degrees

So, 74 - 3 = 71

And 55+54+71 = 180

Sammy earns money for college by walking dogs and mowing lawns. She earns $3 for each dog she walks and $25 for each lawn she mows. Which expression can be used to determine the amount of money she earns from walking w dogs and mowing m lawns

Answers

Answer:

x = 3w + 25m

Step-by-step explanation:

The number of dogs she walks (w) and the number of lawns that Sammy mows (m) need to be multiplied by the amount of money that Sammy makes from each individual action. Both of these products are then added together to equal the total amount of money that Sammy has earned. All of this can be represented with the following expression where x is the total amount of money earned...

x = 3w + 25m

The volunteers at a high school football team's concession stand are trying to decide on the price of the hot dogs they are selling. When they charge $2 for a hot dog, they sell an average of 70 hot dogs per game. With every $1 increase in the price, the number of hot dogs sold per game decreases by 8. The volunteers can calculate the revenue earned from selling the hot dogs at each game using the expression -8x2 + 54x + 140, where x is the number of $1 increases in price.

Answers

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is [tex]-8x^2 + 54x + 140[/tex].

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

=[tex]-8(0)^2 + 54(0) + 140[/tex]

=[tex]140[/tex]

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

can someone pls help me i need to know what is 2x - 1 = 7

Answers

Answer:

The solution for x would be 4.

Step-by-step explanation:

2x - 1 = 7

The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4

Help, please! In the diagram, FH = 1/3AC and 3FG = AB. What additional information is necessary to prove that ΔABC is similar to ΔFGH, using the SSS similarity theorem?

1. 2. 3. BC/GH = 3
4. BC/GH = 1/3

Answers

Answer:   BC/GH = 3

=======================================================

Explanation:

The order of the letters is very important. This is because the order tells us how the angles pair up and that leads to telling us how the sides correspond to one another.

Note with ABC and FGH, the first and last letters are AC and FH respectively. These sides correspond. We're told that FH is 1/3 as long as AC when your teacher wrote FH = (1/3)*AC; we can solve for AC to get AC = 3*FH.

Going back to ABC and FGH, we see that the first two letters of each are AB and FG. This is another pair of corresponding sides. We're told that 3*FG = AB. So AB is three times longer than FG.

So far we can see that

AC = 3*FHAB = 3*FG

The missing information we need is that BC = 3*GH. If we know this, then we can use the SSS similarity theorem to prove the triangles are similar. Note how BC are the two last letters of ABC while GH are the last two letters of FGH.

Starting with BC = 3*GH, we can divide both sides by GH and we get BC/GH = 3.

Step-by-step explanation:

we distribute the 3 and 2 on both sides to get:

we can subtract 3 on both sides to get

3x=2x-5

Now we subtract 2x on both sides to get

x=-5

Answer: 8 + 3/4W

Step-by-step explanation:

From the question, we are informed that Leah is training for a bike race she start by biking 8 miles during every training session and that each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks.

The expression to show the distance Leah bikes in a training session after W weeks will be:

= 8 + 3/4W

For example, after 4 weeks, the distance biked will be:

= 8 + 3/4W

= 8 + (3/4 × 4)
