L (length) = w+16
l x w = Area
260 = l x w
260 = (w+16) x w
260 = w^2 + 16w
w^2 + 16w -260 = 0
(w+26) (w-10) = 0

w= -26 (reject) or w = 10

if w = 10, l = 26
10ft x 16 ft

The ratio of students to adults on a field trip is 8 to 1. Which table correctly shows this ratio for each grade?
elena-14-01-66 [18.8K]

Answer:

The table C correctly shows the ratio 8:1  for each grade

Step-by-step explanation:

Let

x ----> the number of students

y ----> the number of adults

we know that

\frac{x}{y}=\frac{8}{1}

<u><em>Verify each table</em></u>

Table A

grade 6

\frac{96}{88}=\frac{8}{1}

Multiply in cross

96(1)=8(88) ----> is not true

Table B

grade 6

\frac{96}{104}=\frac{8}{1}

Multiply in cross

96(1)=8(104) ----> is not true

Table C

<u><em>grade 6</em></u>

\frac{96}{12}=\frac{8}{1}

Multiply in cross

96(1)=8(12)

96=96 ----> is true

<u><em>grade 7</em></u>

\frac{120}{15}=\frac{8}{1}

Multiply in cross

120(1)=8(15)

120=120 ----> is true

<u><em>grade 8</em></u>

\frac{136}{17}=\frac{8}{1}

Multiply in cross

136(1)=8(17)

136=136 ----> is true

therefore

The table C correctly shows the ratio 8:1  for each grade

Table D

<u><em>grade 6</em></u>

\frac{96}{11}=\frac{8}{1}

Multiply in cross

96(1)=8(11)----> is not true

Please help!!! The sum of three consecutive integers is 9.​
Travka [436]

Answer:

2

Step-by-step explanation:

because they're consecutive, each integer has to come right after the one before it.

if 1st integer is 1, the 2nd should be 2, and the 3rd should be 3.

3 is equal to 1 + 2, or n + 2

hopefully that works
