For a party in kindergarten balloons of three colors were bought: red, green, and yellow. There were 40 red balloons, the number

marta [7]

Answer: Total number of balloons are 100

and part of balloon is blown up is $\frac{1}{20}$ .

Step-by-step explanation:

Since we have given that

Number of red balloons = 40

Number of green balloons is given by

$\frac{3}{5}\times 40\\\\=3\times 8\\\\=24$

Number of yellow balloons is given by

$24\times \frac{3}{2}\\\\=12\times 3\\\\=36$

So, Total number of balloons were brought to the kindergarten is given by

$40+24+36=100$

Number of red balloons are popped is given by

$\frac{1}{20}\times 40\\\\=2$

Number of green balloons are popped is given by

$\frac{1}{12}\times 24\\\\=2$

Number of yellow balloons are popped is given by

$\frac{1}{36}\times 36\\\\=1$

total number of balloons are blown up is given by

$2+2+1=5$

Therefore, Part of balloon is blown up is given by

$\frac{5}{100}=\frac{1}{20}$

Hence, Total number of balloons are 100

and part of balloon is blown up is $\frac{1}{20}$ .

A rental car company charges $42.72 per day to rent a car and $0.10 for every mile driven. Zoey wants to rent a car, knowing tha

Colt1911 [192]

Answer:

7 Days

Step-by-step explanation:

Miles cost:

$0.10 * 200 = $20

Daily Cost

Her budget at this point is $330 because $350 - $20 (the miles)

$330 / 42.72 = Roughly 7.72

Therefore Zoey can drive for 7 days before her budget runs out.

Write the linear equation in slope-intercept form given the following: (-3, 7) and (6, -8)

Viefleur [7K]

Answer:

y = - $\frac{5}{3}$ x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, 7) and (x₂, y₂ ) = (6, - 8)

m = $\frac{-8-7}{6+3}$ = $\frac{-15}{9}$ = - $\frac{5}{3}$ , then

y = - $\frac{5}{3}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (6, - 8) , then

- 8 = - 10 + c ⇒ c = - 8 + 10 = 2

y = - $\frac{5}{3}$ x + 2 ← equation of line
