Plz Help and Thank you :/

Answer:

10%

Step-by-step explanation:

so

3 cupcakes had sprinkles

27 didn't have sprinkles

which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)

so then set up a proportion

part/whole = percent/one hundred

substitute in the given values

3 / 30= precent/100

simplify

1/10 = precent/100

you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer

percent = 10

Answer:

28π, reasonable

Step-by-step explanation:

A. Circumference is 2πr (or dπ), so we plug in 14 for r

this leaves us with 2π14, in which the 2 and 14 can multiply, so we get 28π

B. if we plug 28π into the calculator, you'll get 87.96, so 85cm is reasonable

Step-by-step explanation:

According to the graphic method, the quintic function has a real root at (x, y) = (- 3, 0) and four complex roots.

Quintic functions are polynomics of degree 5, there are numerical and graphical approaches to find real roots of those kind of polynomials. By algebra we know that quintic equations have at a least one real root and at most five real roots.

In this problem we shall use a graphic approach to determine the real roots of the quintic equation, as it offers sufficiency and quickness for analysis. Please notice that a point of the curve is a root if the point lies on the x-axis.

The graph is contained in the image attached below. According to the outcome, the quintic function has a real root at (x, y) = (- 3, 0) and four complex roots.

Answer:

There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.

Step-by-step explanation:

The given information is one type of medicine in 2 decagram container.

Here, we know ,

      1 decagram = 10 grams

and, 1000 milligrams =1 gram

now -: 2 decagram = 2 × 10grams   {since 1decagarm = 10 grams }

                               = 20 grams .

then ,                   = 20× 1000milligrams {since 1 gram = 1000 milligrams}

                           =20,000 milligrams .

Hence, the correct option is D that is 20,000 milligrams .

Answer:

-2

Step-by-step explanation:

First, add 3 to both sides

-5f-3+3=7+3

Simplify

-5f=10

Then, isolate the variable by dividing both sides by -5

-5f/-5=10/-5

Simplify

f=-2

Answer:

[tex]r=\sqrt[3]{\frac{3v}{\pi h} }[/tex]

Step-by-step explanation:

The equation is  v=1/3πr³h

Multiply both sides of equation by 3 to get

3v=πr³h

Divide both sides of the equation by πh to get

3v/πh = r³

Apply cube root on both sides of the equation as;

[tex]\sqrt[3]{\frac{3v}{pih} } =r[/tex]

Answer: [tex]y=5.666667[/tex]   or   [tex]y=5 \frac{6}{9}[/tex] in fraction

Step-by-step explanation:

1. Simplify  -9.8-y+2.8y  to  -9.8+1.8y

0.4=-9.8+1.8y0.4=−9.8+1.8y

2. Regroup terms

0.4=1.8y-9.8

3. Add 9.8 to both sides.

0.4+9.8=1.8y

4. Simplify  0.4+9.8  to  10.2

10.2=1.8y

5. Divide both sides by 1.8

[tex]\frac{10.2}{1.8} =y\\[/tex]

6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667

5.666667 = [tex]y[/tex]

7. Switch sides.

[tex]y=5.666667[/tex]

Answer:

11 1/5 feet!

Step-by-step explanation:

He needs a total of 27 9/10 feet! 11 1/2 + 5 1/5 is 16 7/10 feet! If we need 27 9/10 feet, we subtract 16 7/10 ft from 27 9/10 ft to get 11 2/10, which we can reduce 2/10 to be 1/5.

So, he needs 11 1/5 feet of wood more to build the doghouse for his new puppy!
