Answer:

0.01462069 cost per tablespoon

Step-by-step explanation:

a bag of sugar costs $2.12

145 tablespoons of sugar

145:2.12 is the ratio

1:x where x represents per tablespoon cost

2.12 / 145 = 0.01462069 which rounds up to 0.02

Check if it correct:

145 x 0.01462069 = 2.12

The cost of a customer's smartphone bill can be modeled by

Sergio039 [100]

Answer:

C = (g + 5)

Step-by-step explanation:

Given the cost of a customers smartphone bill,

C=10g+50

We are required to factor the polynomial.

First, determine the G.C.D of both terms

The GCD of 10g and 50 is 10

Next, we divide each of the term by 10 and balance it by multiplying the expression by 10.

C = 10g + 50

= 10 (10g / 10 + 50/10)

The cost polynomial factored is C=10(g+5).

What is the name of the regular polygon that measures 140ﾟ

andrezito [222]

Answer:

The regular polygon is a nonagon

Step-by-step explanation:

The correct question is

What is the name of the regular polygon that each interior angle measures 140ﾟ?

we know that

The formula to find the sum of the interior angles in a regular polygon is equal to

$n(a)=(n-2)180\°$

where

n is the number of sides of the regular polygon

a is the measure of each interior angle of the regular polygon

we have

$a=140\°$

substitute in the formula and solve for n

$n(140\°)=(n-2)180\°$

$140n=180n-360$

$180n-140n=360$

$40n=360$

$n=9\ sides$

The regular polygon has 9 sides

therefore

The regular polygon is a nonagon

A railroad crossing sign has a diameter of 30 inches. what is the area of the sign?

Anna007 [38]

Answer:

706.5m^2

Step-by-step explanation:

The sign is a circle

Area of a circle is (pi)r^2

d = 30 in -> r = d/2 = 30/2 = 15

Area = 3.14 x (15)^2 = 706.5m^2

ASAP—-what is the missing value

olga_2 [115]

Answer:

im sure its 139

Step-by-step explanation:

because you do 128 + 93 which is 221

next, you do 360 (triangle angles) then you do 360-221

which gives you 139!

hope it helped! =)
