Answer:

The only one I can see right now is (C)

Step-by-step explanation:

Because a positive divided by a negative is negative, so 80/-10 is -8.

For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.

By selling a chair for $372, Daisy loses 7%. At what price must she sell it to gain 10%.

serious [3.7K]

Answer: $440

Step-by-step explanation:

Given selling price = $ 372

Loss % = 7%

We know, cost price = selling price × 100/100 - loss%

Therefore, cost price = 372 × 100/100 - 7

= 372 × 100/93

= $400

Now cost price = $400

Gain% = 10%

Therefore, selling price = (100 + gain%)cost price/100

= (100 + 10)400/100

= 110 × 4

= $440

eduard

Answer:

$\boxed{ \text{The temperature of the water in Beaker A will increase.}}$

Step-by-step explanation:

Heat always flows from a hotter object to a colder one. If heat flows from the sphere to the water, $\boxed{\textbf {the temperature of the water will increase.}}$

A is wrong. If the temperature of the water is greater than 8 °C, heat will flow from the water to the sphere.

B is wrong. If the temperature of the water is lower than 8 °C, heat will flow from the sphere to the water..

D is wrong. If heat flows from the water to the sphere, the temperature of the water will decrease.
