In-s [12.5K]

Answer:

188 balloons

Step-by-step explanation:

First, we have to divide the amount he collected altogether by the price of each balloon that he sold to find out how many balloons he sold:

9632 / 86 = 112 balloons

She sold 112 balloons.

We know that she threw 76 balloons away, therefore, the number of balloons she bought was:

112 + 76 = 188 balloons

After a storm, a tree lies as shown. What was the original height of the tree? (Round to the nearest whole foot.)
Andreyy89
Using the Law of Sines, sina/A=sinb/B=sinc/C (although there are other ways considering that this is a 30, 60, 90 degree triangle with a basic identity) we can say:

97/sin60=x/sin30=y/sin90

x=97sin30/sin60 and y=97sin90/sin60

The total height of the tree is h=x+y so

h=97sin30/sin60 + 97sin90/sin60

h≈168.01 ft (to the nearest hundredth of a foot)

h≈168 ft (to nearest foot)

If a number added to five is divided by the difference of the number and two, the result is three-fourths. Find the number.
alexandr1967 [171]

Answer:

x = - 26

Step-by-step explanation:

Let the number be x.

According to the question,

\frac{x+5}{x-2} = \frac{3}{4}\\

Cross multiplying 4 & 3 gives :-

4(x+5)=3(x-2)

And solving this eqn. gives :-

4(x+5)=3(x-2)\\=> 4x+20=3x-6\\=>4x-3x=-20-6\\=>x=-26

Verification :-

(putting the value of x = -26 )

\frac{x+5}{x-2} \\\\=>\frac{-26+5}{-26-2} \\\\=> \frac{-21}{-28} \\\\=>\frac{21}{28}

Reducing  \frac{21}{28}  by 7 gives  \frac{3}{4} .

PLEASE HELP ASAP!! WILL GIVE BRAINLIEST!!
zhenek [66]

Given is :

The area of the rectangular patio is = 130 square feet

Let the width of the patio be = x feet

As length is 3 feet more than the width, so the length is = x+3 feet

Now area of rectangle is = length * width

x(x+3)=130

x^{2}+3x=130

x^{2}+3x-130=0

x^{2}+13x-10x-130=0

x(x+13)-10(x+13)=0

(x-10)(x+13)=0

This gives either x-10=0 or x+13=0

x-10=0 ; x=10

x+13=0 ; x=-13 (neglect this negative value)

So, the width of the patio is = 10 feet

Length = 10+3 = 13 feet
