It’s you birthday and you bought a giant sandwich to feed all of your guests. The sandwich is 10 1/2 feet long and you need to f

Hoochie [10]

Answer: $1\dfrac{3}{4}\text{ feet}$

Step-by-step explanation:

Given: Length of sandwich = $10\dfrac12\text{ feet}=\dfrac{21}{2}\text{ feet}$

Total people = 14

If everyone gets a same sized piece , then length of each piece should be

$\dfrac{\text{ Length of sandwich}}{\text{Total people}}$

$=\dfrac{\dfrac{21}{2}}{14}\text{ feet}\\\\=\dfrac{21}{2\times14}\text{ feet}\\\\=\dfrac{7}{2\times2}\text{ feet}\\\\=\dfrac{7}{4}\text{ feet}\\\\=1\dfrac{3}{4}\text{ feet}$

Hence, length of each piece = $1\dfrac{3}{4}\text{ feet}$

Elana walked 12 miles. then she walked 1/4 that distance. how far did she walk all together. select all that apply.

Nezavi [6.7K]

Answer:

c., d., f

Step-by-step explanation:

"elana walked 12 miles"

That is 12.

"then she walked 1/4 that distance"

That is 1/4 of 12 miles, so it is 1/4 * 12

She walked altogether

12 + 1/4 * 12 = 12 + 3 = 15

She walked altogether 15 miles.

a.12+1/4 = 12.25 which is not 15

b.12×1/4 = 3 which is not 15

c.12+1/4×12 = 12 + 3 = 15 which is correct

d.12(1+ 1/4) = 12(1.25) = 15 which is correct

e.12×3/4 = 9 which is not 15

f.12×5/4 = 15 which is correct

Answer: c., d., f

Given y=5x−3 with the domain D: {−2, −1, 0, 1, 2}, fill in the missing values of the table below.

spayn [35]

Answer:

see below

Step-by-step explanation:

y = 5x-3

Let x = -2 y = 5(-2) -3 = -10 -3= -13

Let x = -1 y = 5(-1) -3 = -5-3 = -8

Let x = 0 y = 5(0) -3 = 0-3 = -3

Let x = 1 y = 5(1) -3 = 5-3 = 2

Let x = 2 y = 5(2) -3 =10-3 = 7

What is the simplified form of (4j2+6)+(2j2-3)

Galina-37 [17]

Answer: $6j^2+3$

Step-by-step explanation:

In order to solve this exercise it is important to remember the multiplication of signs. Notice that:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

In this case you have the following expression given in the exercise:

$(4j^2+6)+(2j^2-3)$

Where the variable is "j".

When you multiply signs, you get:

$=4j^2+6+2j^2-3$

Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is the shown below:

$=6j^2+3$

As you can observe, you get a 2nd degree binomial.
