Is 290.45 higher than 2867.5

tekilochka [14]

2867.5 is bigger

Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first

If you ignore the decimal, your left with
290 vs 2867

2867 is much bigger than 290 so this is the answer

Ruby conducted a survey and found that 5/6 of her classmates have a pet and 2/3 of them are dogs what fraction of her classmates

lina2011 [118]

This is how I would solve it, I would act as if there were 36 people in the class.
36÷6=6×5=30
30÷3=10×2=20
20/36=10/18=5/9
You could also try another number such as 24;
24×(5÷6)=20
20×(2/3)=13.3(3 repeating)
13.333/24=5/9
5/9 people have dogs.
Tell me if this helps.

Choose the solutions to the quadratic equation x2 – 8x – 9 = 0. –21 –1 9 29

8090 [49]

Answer:

-1 and 9

Step-by-step explanation:

To solve the quadratic, factor and set its factors equal to 0. Factoring is the action of breaking up a polynomial into pieces which multiply to make it. The factors are found by multiplying numbers to make C and add to B of $ax^2+bx+c$ .

Here c = -9 and b = -8. The numbers -9 and 1 multiply to -9 and add to -8. These are the factors (x-9)(x+1).

Set each equal to 0 and solve for x.

x-9 = 0

x = 9

x+1 =0

x = -1
