Answer:

$\frac{13}{20}$ .

Step-by-step explanation:

We can begin by converting 65% to a fraction over 100. 65% converts to 0.65, or $\frac{65}{100}$ .

We can simplify this down. Both 65 and 100 share a common factor of 5, which allows us to produce a new fraction:

$\frac{65}{100} = \frac{13}{20}$

Therefore, the simplified version is $\frac{13}{20}$ .

The perimeter of an isosceles trapezoid is 28 in and the ratio of lengths of its bases is 5:3. Find the lengths of the sides of

dalvyx [7]

We are given the
perimeter of isosceles trapezoid = 28 in
ratio of length of bases = 5:3

We are to find the lengths of sides of the trapezoid and the diagonal that bisects the angle at the base with a longer length

The formula for the perimeter of an isosceles trapezoid is
P = (1/2) (b1 + b2) h

We are given the ratio
b2/ b1 = 5 /3
b2 = 5/3 b1
Substituting
28 = (1/2) (5/3 b1) h
The height of the trapezoid is expressed in terms of b1
For the diagonal
d² = h² + [(b2 - b1) + (b2 - b1)/2]²
Express h and b2 in terms of b1 and diagonal can be expressed in terms of b1

Estimate the area of a triangle with a base of 15.22 km and a height of 13.91 km.

BaLLatris [955]

Given a triangle with a base of 15.22 km and a height of 13.91 km. We can find the area of the triangle using the formula below.

$\text{Area of a triangle = }\frac{1}{2}\times\text{base x height}$ $\begin{gathered} \text{Area of triangle = }\frac{1}{2}\times15.22\times13.91 \\ =0.5\times15.22\times13.91 \\ =105.8551\operatorname{km}^2 \end{gathered}$

Answer: The area of the triangle is

$105.8551\operatorname{km}^2$

13.) Springfield Elementary is putting on a school play

Oduvanchick [21]

45 adult tickets and 80 children tickets were sold

Solution:

Let "a" be the number of adult tickets sold

Let "c" be the number of children tickets sold

Cost of 1 adult ticket = $ 6

Cost of 1 children ticket = $ 3.50

They sold a total of 125 tickets

Therefore,

a + c = 125

c = 125 - a --------- eqn 1

They made a total of $550. Therefore, frame a equation as:

number of adult tickets sold x Cost of 1 adult ticket + number of children tickets sold x Cost of 1 children ticket = 550

$a \times 6 + c \times 3.50 = 550\\$

6a + 3.50c = 550 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

6a + 3.50(125 - a) = 550

6a + 437.5 - 3.50a = 550

2.5a = 112.5

Substitute a = 45 in eqn 1

c = 125 - 45

Thus 45 adult tickets and 80 children tickets were sold
