Mr. Malone used 40 pounds of insecticide to cover 1,760 square feet of lawn and 60 pounds to cover an additional 2,640 square feet. how many pounds of insecticide would Mr. Malone need to cover his whole lawn of 4,480 square feet?

Answers

Answer 1

1760/40 = 44
He covered 44 ft^2 per lb.

2640/60 = 44
Again, he covered 44 ft^2 per lb.

In both cases, he covered 44 square feet per pound.
To cover 4480 sq ft, he needs:

4480/44 = 101.818181... = 101 9/11 pounds

A group of fans at a football game are sitting in 7 rows with 28 in each row. In the center, a section of 14 fans in 3 rows and a section of 11 fans in 3 rows have cards spelling out the team name. How many fans do not have a card?

Answers

I believe it would be 75.
I hope this helps

Final answer:

Out of 196 fans, 75 fans have cards. Therefore, 121 fans do not have a card.

Explanation:

The question is asking how many fans do not have a card at a football game. Initially, there are 7 rows of fans with 28 fans in each row, which gives us 196 fans in total (7 * 28). In the center, there are two sections where fans have cards. The first section has 14 fans in 3 rows, which equates to 42 fans (14 * 3), and the second section consists of 11 fans in 3 rows, which makes 33 fans (11 * 3). So, the total number of fans with cards is 75 (42 + 33). To find out how many fans do not have a card, we subtract the number of fans with cards from the total number of fans. Therefore, the answer is 196 - 75 = 121 fans.

What property did Ramon use? 150+214+89=214+89+150

Answers

This is the communicative property. This means you just move the numbers around, but the result will be he same as long as you’re ADDING

Final answer:

Ramon used the Commutative Property of Addition in the equation 150+214+89=214+89+150. This property indicates that the order in which numbers are added doesn't affect the result.

Explanation:

In the given equation, 150+214+89=214+89+150, Ramon is using an important property of addition known as the Commutative Property. The Commutative Property of Addition states that the order in which numbers are added does not change the sum. For example, if we have two numbers, 5 and 3, adding them in any order (5+3 or 3+5) will always give us the same result, which is 8. Hence, in this question, whether you add 150, 214 and 89 in the given order or reverse, the sum remains the same. Therefore, you can see how Ramon made use of the Commutative Property to rearrange the numbers while still keeping the total sum the same.

A. 200 mi.
B. 170 mi.
C. 100 mi.
D. 90 mi.

Answers

The answer is D. 90 miles. You can figure this out by multiplying 15 by 6, as Celia hiked 15 miles every day for 6 days, so 15, 6 times, and 15 x 6 = 90.

Olivia ate four times as much salad as Reagan. If Reagan ate r salad, which equation can be used to find the amount of salad Olivia ate, v?

A. 4r = v
B. r + 4 =
C.v + 4 = r
D. 4v = r

Answers

the answer would be A because if she ate 4 times more then all you have to do is multiply r by four

Answer:

A. 4r = v

Step-by-step explanation:

the amount of salad Reagan ate is r.

If Olivia ate 4 times as much salad as Reagan, then she ate r amount multiplied by 4:

Thus, the equation than can be used to describe the amount of salad for Olivia is:

4r = v

This is because this equation tells us that 4 times the amount of salad Reagan ate (4r) is equal to what Olivia ate (v)

A funnel is made up of a partial cone and a cylinder as shown in the figure. The maximum amount of liquid that can be in the funnel at any given time is 16.59375 cubic centimeters. Given this information, what is the volume of the partial cone that makes up the top part of the funnel?

Answers

The volume of the partial cone is the volume of the entire funnel minus the volume of the cylindrical part.

The volume of a cylinder is given by:

[tex]V=\pi r^2h[/tex]
where: r is the radius of the cylinder and h is the height of the cylinder.

Given that the cylindrical part of the funnel has a height of 1.5 cm and a diameter of 1.5 cm, thus the radius is 1.5 / 2 = 0.75 cm and the volume is given by:

[tex]V=\pi(0.75)^2(1.5)=0.84375\pi=2.65072cm^3[/tex]

Therefore, the volume of the partial cone is given by 16.59375 - 2.65072 = 13.94303 cubic cm.

The volume of 1000 drops of a liquid is 0.1 fluid ounce.
What is the volume of 10,000 drops?

Answers

1 fluid ounce

1000= 0.1

when you add zeros you move the decimal point over to the left making it

10,000= 1fluid ounce

Final answer:

To find the volume of 10,000 drops, if 1000 drops equal 0.1 fluid ounce, we multiply the volume by 10 to get 1.0 fluid ounce.

Explanation:

The volume of 10,000 drops of a liquid, when 1000 drops is equivalent to 0.1 fluid ounce, can be calculated using a simple ratio. If 1000 drops equal 0.1 fluid ounce, then we can multiply both the number of drops and the volume by 10 to find the volume of 10,000 drops:

1000 drops = 0.1 fluid ounce

10,000 drops = 1.0 fluid ounce (since 0.1 fluid ounce x 10 = 1.0 fluid ounce)

Therefore, the volume of 10,000 drops is 1.0 fluid ounce.

solve the equation for y.
xy-7y=49

Answers

We have the equation xy-7y=49.

First, we factor out the common term for "y"
y(x - 7) = 49

Now, divide both sides by x - 7.

y = 49/x-7 <====

The solution of the given equation xy-7y=49 for y is y = 49/(x-7) for all values of x not equal to 7.

To solve the equation xy-7y=49 for y, first we can factor out y from the left side of the equation which gives us y(x-7)=49.

Then we can isolate y by dividing both sides of the equation by (x-7).

This gives us y = 49/(x-7).

This solution assumes that x is not equal to 7 because division by zero is undefined.

Hence, the solution is y = 49/(x-7) for x ≠ 7.

(CESGRANRIO) Determine o parâmetro m na equação x²+mx+m²-m-12=0, de modo que ela tenha uma raíz nula e outra positiva.

Answers

Vamos lá.

Pede-se para determinar o parâmetro "m" da equação abaixo, sabendo-se que uma raiz é nula e a outra é positiva:

x² + mx + m² - m - 12 = 0

Veja que se uma raiz é nula (é igual a zero), então vamos substituir o "x" por "0", na equação acima:

0² + m*0 + m² - m - 12 = 0
0 + 0 + m² - m - 12 = 0
m² - m - 12 = 0 ------resolvendo essa equação do 2º grau você encontrará as seguintes raízes:

m' = -3
m'' = 4

Dessa forma, vamos substituir "m" por (-3) e por 4 e ver se a equação terá uma raiz nula e outra positiva. Vamos ver?

Substituindo "m" por "-3", ficamos com:

x² - 3x + (-3)² - (-3) - 12 = 0
x² - 3x + 9 + 3 - 12 = 0
x² - 3x +12 - 12 = 0
x² - 3x = 0 <------Veja que as raízes dessa equação são: x' = 0 e x'' = 3
Veja que para m = -3, a equação se verifica, pois temos uma raiz igual a "0" e a outra positiva (igual a 3).

Agora vamos substituir "m" por 4 na equação original:

x² + 4x + 4² - 4 - 12 = 0
x² + 4x + 16 - 16 = 0
x² + 4x = 0 <----- Veja que as raízes dessa equação são: x' = 0 e x'' = -4.
Observe que, para m = 4, a equação NÃO se verifica, pois temos uma raiz igual a "0" e a outra negativa (igual a -4). E no enunciado é informado que uma raiz deverá ser nula e a outra positiva. Como deu uma nula e a outra negativa, então m = 4 não convém.

Logo, o valor de "m" deverá ser:

m = -3 <----Pronto. Essa é a resposta.

Can someone explain to me how to solve this/these types of problems? Don't just answer it, explain.

Answers

The easiest method to solve problems like this is to graph the inequalities given and shade the regions that make them true. When you have properly shaded all of the regions, you will find that you have a region which is bounded on all four sides by one of the inequalities, and then you can find the x and y values which correspond to the vertices of the shaded region.

You didn't provide a function that you are trying to maximize in this example, but the idea is that you take all of the (x,y) points which correspond to the vertices and plug them into your objective function. The one which produces the largest value maximizes it (it is a similar process for minimizing it, but you'd be looking for the smallest value). Let me know if you need more help than that, or would like me to work out the example you have provided (I will need an objective function for it though).

The is the value of the missing number?

Given the parameter:

2 1/9 of what number is 76?

Now, we set up the equation:

Let 'x' represent the unknown number:

19/9 of x is 76

19/9 × x = 76

Solve for x:

19x/9 = 76
