B^2 -4ac is the discriminant
5^2 -4*1*7
25-28= -3
Since the discriminant is negative the answer will be D non real roots.

Snowy's Snow Cones has a special bubble gum snow cone on sale. The cone is a regular snow cone that has a spherical piece of bub

cupoosta [38]

Let us first note down all the information's that are given in the question.

Radius of the snow cone = 4 inches

Height of the snow cone = 6 inches

Diameter of the bubble gum = 0.8 inches

Then

Radius of the bubble gum = 0.4 inches

Now

Volume of the come = 1/3 * pi * (radius)2 * height

= 1/3 * 3.14 * (4) ^2 * 6

= 3.14 * 16 * 2

= 100.48 cubic inches

Again

Volume of the sphere = (4/3) * pi * (radius)^3

= (4/3) * 3.14 * (0.4)^3

= (4/3) * 3.14 * 0.064

= 0.2679 cubic inches

Volume of the cone

that can be filled with flavored ice = 100.48 - 0.27

= 100.21 cubic inches

The correct option among all the options that are given in the question is option "d".

Answer:

Step A) 250 times 3 months + 500 cause you already have that in your bank account= 1250

Step B) 12+12=24 so 250 times 24=6000+ 500 cause you already have that in your bank account= 6500

Step C) 8,300- 6500= 1800 then, 250 time 5 + 500= 1750, and 250 times 6 = 1500+500=2000 so you can go with whatever.

Step D) 3 years= 36 months so 250 times 36 months= 9000 so in three yrs you should have about 9500 bc you need to add the 500 on again. sry I could not do the graph but I hoped I helped. :)

A florist is arranging flowers in vases. There are 4 red flowers and 5 white flowers in every vase. The florist wants to make on

vichka [17]

There will be 72 flowers in total in the large arrangement.

Step-by-step explanation:

No. of red flowers in vase = 4

No. of white flowers in vase = 5

Ratio of red flowers to white flowers = 4:5

No. of red flowers in large arrangement = 32

No. of white flowers in large arrangement = w

Ratio of red flowers to white flowers = 32:w

Using proportion;

Ratio of red flowers to white flowers :: Ratio of red flowers to white flowers

$4:5::32:w$

Product of extreme = Product of mean

$4*w=32*5\\4w=160$

Dividing both sides by 4

$\frac{4w}{4}=\frac{160}{4}\\w=40$

Total flowers in large arrangement = Red flowers + white flowers

Total flowers in large arrangement = 32 + 40 =72

There will be 72 flowers in total in the large arrangement.
