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}

4. What is the axis of symmetry for h(x) = 19(x – 5)^2 + 6
tester [92]

Answer:

x = 5

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k ) are the coordinates of the vertex and a is a multiplier

h(x) = 19(x - 5)² + 6 ← is in vertex form

with vertex (h, k ) = (5, 6 )

The axis of symmetry is a vertical line passing through the vertex

with equation x = 5

What is 12/42 when you simplify it 
VashaNatasha [74]
First of all, to simplify a number/fraction, you must find a common multiple.
Both 12 and 42 is divisible by 6
\frac{12}{42}=\frac{2}{7} since 6 goes into 12, two times and goes into 42, 7 times. The answer is \frac{2}{7} when simplified.
