Answer: I think there is a mistake for the first one because I did the math and I got 200 added but then there are more answers to this one, I added all the others by 200 and got the next number but then when I got to 6,300 I can't get the 6,700. I get something else, I add 6,000 with 200, and then I get 6,200 instead of getting 6,300. Then I added that 6,200 and 200 and got 6,400. I am confused with the second one, can you please help me understand that one. The third one is also confusing, The one is 12 nuggets eaten per minute. The fifth I am not sure if that is a solvable question, The sixth one I am not sure but I think that it is 0.066667. The seventh one doesn't even make any sense to me.

Explanation: I am sorry this was so long, I was trying to make sense of these questions. Also if this is ALL wrong sorry for even trying.

Answer:

2,279 gallons of gas.

Step-by-step explanation:

Given;

total number of cars in the race, t = 43 cars

total distance traveled by each car, d = 265 miles

5 miles ---------------- 1 gallon of gas

265 miles ------------ x gallon of gas

x = 265 / 5

x = 53 gallons

Total gallons of gas used by the 43 cars in the race is given as;

Total gallons of  gas = 53 gallons x 43 cars

Total gallons of  gas = 2,279 gallons of gas.

Therefore, the toal gallons of gas the cars used altogether to finish the race is 2,279 gallons.

Answer:

10,203 meters tall

Step-by-step explanation:

Sea Level is given a value of 0 and is measured as the starting point. Anything below sea level would be a negative value. Therefore, to calculate the total height of Mount Mauna Kea we would need to add the height below sea level with the height above sea level as both positive values.

5854m + 4349m = 10,203m

Finally, we can see that Mount Mauna Kea is 10,203 meters tall.

Answer : [tex]16^a - b^2[/tex]

[tex](4a + b) (4a - b )[/tex]

[tex]= (4a + b) (4a - b )[/tex]

[tex]= (4a) (4a) + ( 4a) (-b) + (b)(4a) + (b) (-b)[/tex]

[tex]= 16^a - 4ab + 4ab - b^2[/tex]

[tex]= 16^a - b^2[/tex]

Answer:

8

Step-by-step explanation:

Sea el número x El cuadrado será x ^ 2

Entonces la suma será; x ^ 2 + x = 72 x ^ 2 + x-72 = 0

x ^ 2 + 9x-8x-72 = 0

x (x + 9) -8 (x + 9) = 0

(x + 9) (x-8) x = 8 o -9

Como solo estamos considerando números naturales, la respuesta correcta es 8

Answer: first one x= -9/7y+-10/7, second x=2/3y+25/3

1. Step-by-step explanation:

add 9y to both sides -7x-9y+9y=10+9y

divide both sides by -7. -7x/-7=9y+10/-7

2. Add 2y to both sides. 3x-2y+2y=25+2y

divide both sides by 3. 3x/3=2y=25/3

Answer:

He now weighs 131 pounds.

Step-by-step explanation:

You can work backwards.

Past weight - 7 = 124

Past weight = 124 + 7

Past weight= 131

Answer:

2211

Step-by-step explanation:

1*3 = 3

3/3 = 1

1+25 = 26

26-3 = 23

23*100 = 2300

2300-93 = 2207

2207+4 = 2211

Answer:

13

Step-by-step explanation:

a^2 + b^2 = c^2

11^2 + 7 ^2 = c^2

121 + 49 = 170

√170 = 13.04

Answer:

c = 13.0

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 11² + 7² = 121 + 49 = 170 ( take the square root of both sides )

c = [tex]\sqrt{170}[/tex] ≈ 13.0 ( to the nearest tenth )

Answer:

2 hours

Step-by-step explanation:

First, we notice that the time taken to paint a fence is inversely proportional to the number people used because as the number of people increase, the time taken to paint the fence decreases.

5 people can paint a fence in 4 hours.

1 person can paint a fence in = 5 x 4

                                                = 20 hours

10 people can paint the fence in = 20/10

                                                      = 2 hours
