Answer:

$29.93

Step-by-step explanation:

First, we take the discount off of the original price.

We need to find the discount amount in dollars.

30/100=.3 this is 1%.

.3 * 5 = 1.5 He will get $1.50 off of his purchase.

30 - 1.5 = 28.5.

Next we will add tax. We need to find tax in dollars.

28.5/100=.285 this is 1%

.285 * 5 = 1.43 He will get $1.43 of tax on his purchase.

28.5 + 1.43 = 29.93

He will pay $29.93 for his wind chime.

Kayla wants to find the width, AB, of a river. She walks along the edge of the river 65 ft and marks point C. Then she walks 25

AlladinOne [14]

Answer:

Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles

Part B) The width of the river is about $39\ ft$

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

Part A) we know that

In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent

m<DCE=m<ACB -----> by vertical angles

m<EDC=m<ABC -----> is a right angle

m<DEC=m<CAB -----> the sum of the internal angles must be equal to 180 degrees

Part B) we know that

The triangles ABC and EDC are similar -------> see Part A

therefore

$\frac{BC}{DC}=\frac{AB}{DE}$

substitute the values and solve for AB

$\frac{65}{25}=\frac{AB}{15}$

$AB=15*(\frac{65}{25})=39\ ft$

Each calendar will sell for $5 each write an equatio to model the total income for selling calendars

Brrunno [24]

To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
total income = 5x
If we let total income be y, our equation is further simplified into,
y = 5x

The value of y is inversely proportional to the value of x. When y=42, x=6.

NARA [144]

Because $x$ and $y$ are inversely proportional, there is some constant $k$ such that

$xy=k$

Given that $y=42$ and $x=6$ , we have

$k=6\times42=252$

So when $x=9$ , you have

$9y=252\implies y=\dfrac{252}9=28$

The area of a rectangular playground is 16 square yards. the length of the playground is 4 times longer than its width. find the

OLga [1]

W= width
l= length= 4w

Area= lw
16 square yards= lw
substitute l=4w for l
16= (4w)(w)
16= 4w^2
divide both sides by 4
4= w^2
take the square root of 4
2 yards= w

LENGTH
l=4w
l=4(2)
l=8 yards

CHECK:
16= (8)(2)
16= 16

ANSWER: The length is 8 yards and the width is 2 yards.

Hope this helps! :)
