There were 230 shoppers at an electronics store on opening day. The specials that day allowed 21% of shoppers to receive a free

anastassius [24]

Answer:

a) About 48 of the shoppers, that is $230\frac{21}{100}$ of the shoppers, received a free set of earbuds.

b) About 58 shoppers, that is $\frac{230}{4}$ received $5 off their first purchase.

Step-by-step explanation:

a. About how many shoppers received a free set of earbuds?

21% out of 230. So

$230\frac{21}{100} = 2.3(21) = 48.3$

About 48 of the shoppers, that is $230\frac{21}{100}$ of the shoppers, received a free set of earbuds.

b. About how many shoppers received $5 off their first purchase?

25% out of 230, so:

$230\frac{25}{100} = 230\frac{1}{4} = \frac{230}{4} = 57.5$

About 58 shoppers, that is $\frac{230}{4}$ received $5 off their first purchase.

Felipe's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A costs Felipe $4.55 per lb. Type B costs $5.7

RUDIKE [14]

Answer:

Type A coffee in lbs = 97 lbs

Step-by-step explanation:

Type a = 4.55/lbs = x

type b = 5.70/lbs = y

Total in lbs = 147lbs

total in sales = 726.50

First,

x + y = 147 lbs -------------------equ 1

4.55x + 5.70y = lbs ------------ equ 2

Multiply equ 1 by 4.55

4.55x + 4.55y = 668.85 -------------equ 3

4.55x + 5.70y = 726.50 ------------equ 4

Subtracting equ 3 from equ 4

1.15y = 57.65

y = 50

Substituting y = 50 into equ 1

x + 50 = 147

x = 97

triangle abc has vertices at a(-2 3),B(0,3),c(-1,-1). Find the coordinates of the image after a reflection over the x-axis.

Crazy boy [7]

The new coordinates of the triangle after reflection from x-axis would be A(-2, -3) , B(0, -3) and C( -1, 1 )

Explanation:

The vertices of the triangle are A(-2 3), B(0,3), C(-1,-1)

The reflection is over the x-axis.

When the reflection is along the x-axis, the coordinates of x does not change. However, the coordinates of y does change.

The negative value of y becomes positive and the positive value of y becomes negative.

Similarly,

A(-2, 3) would become A(-2, -3)

B(0, 3) would become B(0, -3)

C(-1, -1) would become C( -1, 1 )

Therefore, the new coordinates of the triangle after reflection from x-axis would be A(-2, -3) , B(0, -3) and C( -1, 1 )
