a truck that can carry no more than 6400 lb is being used to transport refrigerators and upright pianos. Each refrigerator weighs 250 lb and each piano weighs 475 lb. Write and graph an inequality to show how many refrigerators and how many pianos that truck could carry . WIll 12 refridgerators and 8 pianos overload the truck? Explain.

Answers

I'm not going to do the entire question, but I'll do the first part.

For the first part, you have to set up an inequality. Use context clues, such as no more than (the one used in this sentence) to figure out what the symbol should be for the inequality.
In this case, because it is NO MORE THAN 6400, it would be:

6400[tex] \leq[/tex]250r + 475p

where r represents the # refrigerators, and p represents the # pianos

Now that you have the equation, make the graph, then for the 3rd part, plug in 12 and 8 to r and p to see if it keeps the inequality true.

Hope this helps! :)

Answer: 250 r+ 475p≤ 6400

12 refrigerators and 8 pianos will overload the truck.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Truck capacity: 6400 (no more than means that the weight of the products must be equal to 6400 lbs or less) Weight of one piano: 475 Weight of one refrigerator: 250

So, the inequality that represents this case is :

250 r+ 475p≤ 6400

Where:

r = number of refrigerators

p = number of pianos

For 12 refrigerators and 8 pianos we simply replace the values:

250 (12) + 475 (8) ≤ 6400

3000+3800≤ 6400

6800≤ 6400

6800 lbs will overload truck. Because 6800lbs exceeds the capacity of the truck.(6400 lb)

Mrs. Gomez is a mother to 2 boys. The number of children she has is three times the number of boys she has. Her children are planning to buy her a bouquet of flowers. What is the biggest bouquet they can buy in which the ratio of pink flowers to blue flowers matches the ratio of girls to boys if the florist has 9 blue carnations and 12 pink carnations left?

Answers

There are 6 children total, 4 of which are girls. The ratio is 2:1 girls:boys, so there will need to be twice as many pinks as there are blues. If we get 12 pinks, then there will be 6 blues. That's the biggest since that's all the pinks the florist has.

-14=y

Hello,

Any line that is perpendicular to another line has a negative reciprocal of the slope. So the negative reciprocal of -2/3 is 3/2. Now with the new slope, let's pt it in the equation to find the slop-intercept equation BY using point-slope form: y-y1 = m (slope) (x-x1).

If I put the numbers in the equation, it would look like: y+8 = 3/2 (x-4). Let's simplify by distributing 3/2 to the parenthesis: y + 8 = 3/2x - 6.

To get "y" by itself, let's subtract 8 from both sides: y = 3/2x - 14.

So, the equation is now y = 3/2x - 14.

In the box you would write, "-14".

I hope this helps!

Estimate the value of 9.9 squared x 1.79

Answers

Final answer:

To estimate the value of 9.9 squared times 1.79, round 9.9 to 10, square it to get 100, and multiply by 1.79 to get an estimate of 179.

Explanation:

The question asks to estimate the value of 9.9 squared times 1.79. To estimate this value, we can round 9.9 to the nearest whole number, which is 10. Then we square 10 to get 100, and multiply this by 1.79.

So, the estimated value would be:

102 × 1.79 = 100 × 1.79 = 179

This estimation approach uses basic arithmetic principles and rounding techniques to simplify the calculation.

What number needs to be added to both sides of the equation in order to complete the square?
x^2+16x=18

Answers

you have to subtract 18 from both sides

x^2 + 16x = 18

x^2 + 16x (-18) = 18 -18

x^2 + 16x - 18 is your answer :D

Answer: c = 64
In order to find the 'c' value to complete the square, you use the equation c = (b/2)^2. Since 16 = b, c will equal 64. 16/2 = 8, and 8^2 = 64. The final resulting equation will be (x+8)^2 = 82.

In George’s neighborhood there are 33 cats and 33 dogs roaming free.What percent of the animals roaming free are dogs?

A.35%

B.40%

C.45%

D.50%

Answers

First, we'll figure out how many animals there are in total by adding up the cats and the dogs. In this case, we have 33+33=66 total animals. Then we need to figure out what fraction of these 66 animals are dogs:
[tex]\frac{33}{60}=\frac{1}{2}[/tex]

So half of the animals are dogs. To write that as a percent, we need the fraction to be over 100, so:
[tex]\frac{1}{2}=\frac{50}{100}[/tex]

50% of the animals are dogs.

Cody was going to sell all of his stamp collection to buy a video game. after selling half of them he changed his mind. he then bought seventeen more. how many did he start with if he now has 44?

Answers

Final answer:

Cody started with 54 stamps in his collection. The problem was solved using basic algebra by setting up an equation and working backwards.

Explanation:

The subject of this question is mathematics, specifically dealing with a basic algebra problem that requires working backwards to find the original number of items in a collection. To solve the problem, we can set up an equation to represent the scenario given:

Cody sells half of his stamp collection.After changing his mind, he buys seventeen more stamps.He now has a total of 44 stamps.

Let's call the original number of stamps 'x'. After selling half of them, Cody would have ½x. When he buys seventeen more stamps, the equation to represent this situation is ½x + 17 = 44. To find the value of 'x', we need to subtract 17 from both sides of the equation, which gives us ½x = 44 - 17 or ½x = 27. To find the full value of x, we multiply both sides of the equation by 2, which gives us x = 27 * 2 or x = 54.

Therefore, Cody started with 54 stamps in his collection.

The Quotient would be 1012 so I would just put 1000 if your supposed to estimate.

So to estimate here, I would set 29,376 to 29,000 divided by 29, which would make things a lot easier.

29,000/29 = 1,000

So your estimate is about 1,000.
