A pair of basketball shoes was originally priced at $80, but was marked up 47.5%. What was the retail

1 answer:

6 0

47.5% in decimal form is 0.475.

Since the price was increased, we add 1 to 0.475 to get 1.475.

80 * 1.475 = 118

Another way to solve this is to multiply 80 by 0.475, which is 38, then add it to 80.

The retail price of the shoes is $118.

Answer:

126 customers

Step-by-step explanation:

90/500=0.18

that means that 18% of all customers were surveyed.

Need help on 8 and 9 please!!

Georgia [21]

Answer:

for question no. 8 there is a formula in coordinate geometry which i don't remembered .

but can help in solving question no. 9

solution for 9

it is given that values varies directly that means

X1 = X2

Y1 Y2 we have to find Y2

i.e. 9/5.4= -10/Y2

or Y2 × 9 = 5.4 × -10

Y2 = -54/9

Y2 = -5

2. Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral A'B'C'D. Which rule best rep

Virty [35]

Answer:

$(x,y) => (2.5x,2.5y)$

Step-by-step explanation:

Given

See attachment for ABCD and A'B'C'D'

Required

Determine the dilation rule

Using AB and A'B' as points of references;

$AB = (-1,2)\ to\ (2,1)$

$A'B' = (-2.5,5)\ to\ (5,2.5)$

The dilation factor (k) is calculated as:

$k = \frac{A'B'}{AB}$

This gives:

$k = \frac{(-2.5,5)}{(-1,2)} \ or\ k = \frac{(5,2.5)}{(2,1)}$

Factorize

$k = \frac{2.5*(-1,2)}{(-1,2)} \ or\ k = \frac{2.5*(2,1)}{(2,1)}$

$k = 2.5 \ or\ k = 2.5$

Hence, the scale factor is 2.5

The dilation rule is:

$(x,y) => k(x,y)$

$(x,y) => 2.5(x,y)$

$(x,y) => (2.5x,2.5y)$

Anyone know the area of the blue area?

Studentka2010 [4]

First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle.
area of the larger sector:(230/360)π*11.1²≈247.17
area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130
(11.1*11.1*sin130)/2≈47.19
the total area is 247.17+47.19≈294.4
Please use your calculator to double check my numbers.
