Can you help me on this

Answer:

The answers are x < -65, x > 85, x < 180, x<= -13, and x >=25.

Step-by-step explanation:

For the first three, there's an open circle so the sign for the inequality would be < or > but for the last two, there's a closed circle so the sign for the inequality would be <= or >=, the ones with a line underneath. For 1, 3, and 4, the line goes to the left, showing that x is a number less than the point so it would have <, the less than sign. For 2 and 5, the line goes to the right, showing that x is a number greater than the point so it would have >, the greater than sign.

There's a trick to figuring out the right sign. If the line is pointing to the left, the inequality would be x < __, and the sign is pointng to the left. If the line is pointing to the right, the inequality would be x > __, and the sign is pointng to the right. This only works is x is on the left side of the inequality.

To help answer this question, Deigo wrote the division equation 3/4 divided by 2/5. Explain why this equation does not represent

Mars2501 [29]

Answer:

The fraction of the rain filled in the gauge will be = $\frac{8}{15}$

Diego wrote the division equation incorrectly.

It must be given as $\frac{2}{5}$ divided by $\frac{3}{4}$ .

Step-by-step explanation:

Given:

After $\frac{3}{4}$ of an hour of rain the rain gauge is $\frac{2}{5}$ filed.

To find the fraction of the rain that will be filled in the gauge if it continues to rain at the same rate for 15 more minutes.

Solution:

15 minutes in hours will be = $15\ min \times \frac{1\ hour}{60\ min}$ = $\frac{1}{4}$ of an hour.

Given that it has rained for $\frac{3}{4}$ of an hour, and it continues to rain for $\frac{1}{4}$ of an hour more.

Thus, total time of rain will be = $\frac{3}{4}+\frac{1}{4}=\frac{4}{4}=1\ hour$

Using unitary method to find the fraction of rain filled in the gauge after 1 hour of rain.

If in $\frac{3}{4}$ of an hour of rain the rain gauge is $\frac{2}{5}$ filed.

Thus, in 1 hour of rain the gauge will be filled by = $\frac{2}{5}\div \frac{3}{4}$

To divide fractions, we take reciprocal of the divisor and replace division by multiplication.

⇒ $\frac{2}{5}\times\frac{4}{3}$

⇒ $\frac{8}{15}$

Thus, the fraction of the rain filled in the gauge will be = $\frac{8}{15}$

Diego wrote the division equation incorrectly.

It must be given as $\frac{2}{5}$ divided by $\frac{3}{4}$ .
