a rectangular sheet cake is 18 inches long, 12 inches wide, and 3 inches tall. if one jar of frosting covers 120 square inches, how many jars are needed to frost the cake?

Answer:

Factor and set each factor equal to zero.

g=2a

345

Step-by-step explanation:

The area decreases by 1155.52 square meters

What we must do is calculate the area before and after making the diameter cut.

The area of a circle is equal to:

a = pi * r ^ 2

now the diameter is equal to:

d = 2 * r

therefore r,

r = d / 2

before the cut would be

r = 96/2

r = 48

replacing in the area formula

a1 = 3.14 * 48 ^ 2

a1 = 7234.56 square meters.

after cutting the diameter decreases by 8, that is, 96 - 8 = 88, calculating the radius would be:

r = 88/2

r = 44

now calculating the new area would be:

a2 = 3.14 * 44 ^ 2

a2 = 6079.04 square meters.

now we calculate the difference

a1 - a2 = 7234.56 - 6079.04

= 1155.52 square meters

means that the area decreases by 1155.52 square meters

Answer:

C

Step-by-step explanation:

Mean is all the numbers in the list added / the number of numbers

(Ex: 14, 13, 15, 17

Mean = (13 + 14 + 15 + 17) / (number of numbers in the list)

Mean = 59 / 4

Mean = 14.75)

Range = (The largest number - the smallest number)

Mode is the number that appears the most

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number

________________________________________________________

Mean of Ernie = 19

Mean of Lori = 17.6

A is False

Range of Ernie = 7

Range of Lori = 8

B is false

Median of Ernie = 18

Median of Lori = 18

C is true

Mode of Ernie = 17

Mode of Lori = 18

D is false

Answer:

Good seats sold=80

Poor seats sold=130

Step-by-step explanation:

g + p = 210 seats.  Then p = 210 - g.

($5)g + ($2)p = $660.  Substite 210 - g for p,

($5)g + ($2)(210 - g) = $660

Simplify, 5g + 420 - 2g = 660 => 3g = 240  =>  g = 80

80 and 130

Answer:

Step-by-step explanation:

Given the slope-intercept form:[tex]y=\frac{1}{3}x-2[/tex]

Slope-intercept form: [tex]y=mx+b[/tex]

We substitute our x-values (-9, -3, 0, 6, and 9) for x in [tex]y=\frac{1}{3}x-2[/tex] to find the y-values.

For -9:

For 0:

[tex]y=\frac{1}{3}x-2 < ==substitute\ 0\ for\ x\\\\y=\frac{1}{3}(0)-2 < ==any\ number\ multiplied\ by\ 0\ equals\ zero\\\\y=\frac{0}{3}-2 < ==divide\ (don't\ forget\ the\ signs)-zero\ divided\ by\ any\ \#\ equals\ 0\\\\y=0-2 < ==add\ or\ subtract\\\\y=-2 < =value\ of\ y\\\\(0,-2)[/tex]

Answer:

11 soccer balls (rounded estimate; should be close to 11)

Step-by-step explanation:

Because you need to match the limit, you first have to convert in. to ft. That will get you at 2.3 (it is an non-stopping number, so I rounded to the tenths). 11 x 2.3 is  25.3. You can’t go lower, so you have to have that extra soccer ball. Hope this helps.

AM = MB

CM = common side

∠3 = ∠4

△AMC ≅ △BMC

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

CM ⊥ AB

∠3 = ∠4

We have to prove △AMC ≅ △BMC.

Now,

If CM ⊥ AB

AM = MB

Now,

AM = MB

CM = common side

∠3 = ∠4

△AMC ≅ △BMC

Thus,

AM = MB

CM = common side

∠3 = ∠4

△AMC ≅ △BMC

Answer:

5√15

Step-by-step explanation:

(√3 + √48)(√20 - √5)

step 1 simplify √48

(√3 + 4√3)(√20 - √5)

step 2 add √3 and 4√3

(5√3)(√20 - √5)

step 3 simplify √20

(5√3)(2√5 - √5)

step 4 subtract √5 from 2√5

(5√3)(√5)

step 5 multiply 5√3 and √5

= 5√15

explanation of each step

step 1 and 3

To simplify radicals you list the factors of the number under the sqaure root

For 48 we have 2 × 2 × 2 × 2 × 3

We then pair the factors off as powers of 2 if possible

We get 2² × 2² × 3 which can further be simplified as 4² × 3

We then list the number with the power on the outside of the radical and leave the numbers with no power on the inside to get 4√3.

This process is used to simplify √20 as well.

step 2 and 4

For these two steps we are adding and subtracting radicals  with the same radicand ( number inside of the square root. ) This is very simply as we keep the radicand the same and just perform the operation to the coeffecients ( number on the outside of the square root )

Eg. a√b + c√b = (a+c)√b or a√b - c√b = (a-c)√b

Hence, 4√3 + √3 = (4+1)√3 = 5√3

Step 5.

Finally we multiply the two radicals. This is very simply as we can use the rule to do so.

a√b × c√d = (a×c)√b×d

Hence, 5√3 × √5 = (5×1)√(3×5) = 5√15
