hammer [34]

Answer:

Online store will save the most money

Step-by-step explanation:

Amount used in Physical store

Batteries 2packs @$5.99 cost = $5.99*2=$11.98

Stereo 1 system @$100 cost = $100*1=$100

CDs 3 CDs @$7.95 cost = $ 23.85

Total cost= $11.98+$100+$23.85= $135.83

Applying the 10% off coupon = 90/100 * $135.83 =$ 122.25

Applying sale tax 5% = 105/100 * 122.25=$128.36

Amount to spend when using physical store= $128.36

Now calculate for the online store

Batteries 2packs @$4.99 cost= $4.99*2=$ 9.98

Stereo 1 system @$90 cost= $ 90 *1= $90

CDs 3 CDs @$8.95 cost = $8.95*3=$26.85

Total cost=$9.98+$90+$26.85=$126.83

Applying the 5% off coupon= 95/100*126.83=$120.49

Applying the sale tax, $6.99+$120.49=$127.48

Comparing the two ways,

Physical store= $128.36

Online store=$127.48

Online store will save the most money by ($128.36-$127.48)=0.88

What is the circumference of 26 cm

IgorC [24]

Answer:530.9

Solution Steps:

Area of a circle in terms of radius:

Area = π . r2 = 3.14 × 132 = 530.9 square cm.

In terms of diameter:

Area = π . (d/2)2 = 3.14 × (26/2)2 = 3.14 × (13)2 = 530.9 square cm.

In terms of circumference:

Area = C2/(4π) = 81.682/4π = 6671.62/(4 × 3.14) = 6671.62/(12.56) = 530.9 square cm.

Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.

A circle of radius = 13 or diameter = 26 or circunference = 81.68 cm has an area of 530.9 square centimeters which is equal to:

5.309E-8 square kilometers (km²)

0.05309 square meters (m²)

1.312E-5 acres (ac)

5.309E-6 hectares (ha)

2.05E-8 square miles (mi²)

0.0635 square yards (yd²)

0.5715 square feet (ft²)

82.29 square inches (in²)

Which of the following represents the distance between the y-intercept and x-intercept of the line whose equation is y = 3x + 12

Arturiano [62]

Answer:

√160

Step-by-step explanation:

For y-intercept, we use y = mx + c. Comparing both, y = mx +c & y = 3x + 12

y intercept = c = 12

Point is (0, 12)

For x intercept, we use y = m(x - d). We have

y = 3x + 12 → y = 3(x - (-4))

Compare both, x intercept = d = - 4

Point is (-4, 0)

Using distance formula,

Distance = √(0-12)² + (-4-0)² = √12²+4²

Distance = √144+16 = √160
