Answer:

19 weeks

Step-by-step explanation:

You'll be looking for an equation the form of

y=mx+b

Given:

b = $103.50

m = $5.50

x = ? (where x is in weeks)

Next, set y = 0

--> mx+b = 0

Rearrange

x = (-b/m)

Plug in b and m:

x = (-(-103.5)/5.5) = 18.818

Rounding up, it will Martha 19 weeks to save enough money.

Answer:

The answer is $0.45.

Step-by-step explanation:

Divide 12 by 5.40 and there's your answer.

12 / 5.40 = 0.45

Rate of per can is $0.45 per

Given that;

Number of cans bought buy Tangela = 12 cans

Total amount paid = $5.40

Find:

Rate of per can

Computation:

Rate of per can = Total amount paid / Number of cans bought buy Tangela

Rate of per can = 5.40 / 12

Answer:

  60

Step-by-step explanation:

The exterior angles of the polygon are the supplement of the interior angles, so are ...

  180° -174° = 6° . . . . measure of each exterior angle

The sum of exterior angles is 360°, so ...

  n(6°) = 360°

  n = 360°/6° = 60

The polygon has 60 sides.

Answer:

The polygon has 60 sides.

Step-by-step explanation:

Each interior angle = 174°

Each exterior angle = 180° - 174° = 6°

Sum of all exterior angles = 360°

6x = 360° (x = no. of exterior angles)

x = 360°/6

x = 60

If it has 60 exterior angles it has 60 interior angles.

Answer:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

9 and 8 are linear and 10 is non linear

Step-by-step explanation:

an = dn - c

The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.

For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:

an = 2n - 1.

Answer:

Step-by-step explanation:

1 yard is equal to 3 feet.

since you have 3 yards, it'll be 9 feet.

13.14/9 to get your answer

or $1.46 per foot

The price per foot of wrapping paper is $1.46.

First, we need to convert 3 yards to feet. There are 3 feet in 1 yard, so 3 yards is equal to 3 * 3 = 9 feet.

The price per foot is simply the total price divided by the number of feet. In this case, the total price is $13.14 and the number of feet is 9, so the price per foot is:

price per foot = $13.14 / 9 feet

= $1.46 per foot

Therefore, the price per foot of wrapping paper is $1.46.

Answer:

No, the package will not be labeled "heavy"

Step-by-step explanation:

1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).

2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.

3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.

4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.

Final) so in the end, you would have 10lb. 13oz.

Answer:

x= -27 y=18

Step-by-step explanation:

plug in zero for x to find y and plug in zero for y to find x

Answer:  The x-intercept is (-27,0)

The y intercept is (0,18)

Step-by-step explanation:

For the x- intercept, Substitute 0 for y and solve for x

-2x + 3(0) = 54

-2x + 0 = 54

x = 54/-2

x = -27

For the y -intercept, Substitute 0 for x and solve for y

-2(0) + 3y = 54

0 + 3y = 54

y = 54/3

y = 18
