Answer:

Second graph

Step-by-step explanation:

The second graph is the correct one. Why? because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.

After solving $1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}$ we get y=0.24

Step-by-step explanation:

We need to solve the ratio: $1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}$ and find value of y

Solving:

$1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}$

Converting fractions into decimals

$1.32:3.14=(1.4y):0.83$

Ratio can be written as:

$\frac{1.32}{3.14}=\frac{1.4y}{0.83}$

Now cross multiply

$1.32*0.83=1.4y*3.14$

$1.09=4.39y$

$y=\frac{1.09}{4.39}$

$y=0.24$

So, after solving $1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}$ we get y=0.24

Jaden and cadence share a reward of $140 in a ratio of 2/5. what fraction of the total reward does Jaden get? how do you know?

ryzh [129]

So, we need to divide the reward into 5 parts, then award 2 parts to Jaden and 3 parts to Cadence.

$140 / 5 = $28

Jaden gets 2 * 28 = $56
Cadence gets 3 * 28 = $84

$56 + $84 = $140
