Find the value of x,

Gekata [30.6K]

Answer: x = -7

Concept:

From the given graph, we can see that it is an isosceles triangle since the two base angles are congruent.

In geometry, an isosceles triangle is a triangle that has two sides of equal length.

If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.

Solve:

Given information

First Side = 7

Second Side = x + 14

Given expression deducted from the definition of an isosceles triangle

Second Side = First Side

Substitute values into the expression

x + 14 = 7

Subtract 14 on both sides

x + 14 - 14 = 7 - 14

$\boxed{x=-7}$

Hope this helps!! :)

Using the solubility curve, choose all of the statements that are correct.

irinina [24]

Answer:

See explanation below

Step-by-step explanation:

According to the solubility curve attached, let's analyze each sentence to see which one is correct:

"Solubility of NaCl is least affected by temperature"

True. as you can see in the curve, solubility of NaCl remains almost constant at any value of temperature, so in this case, it does not matter the temperature, the NaCl solubility will be the same.

"completely dissolve 60 g of KBr in 100 g of water at 20 °C"

True. As you can see in the graph, solubility of KBr begins at 60 g, so in 20 °C we have something dissolved there. Actually you have like 70 g dissolved there, so, this is true.

"The solubility of KNO3 is the least affected by changes in temperature"

False. The curve for KNO3 is exponencial, so, changes in temperature do actually affect the solubility.

"100 g of KBr will dissolve completely in 100 g of water at 75 °C"

False. According to the curve, 100 g dissolve when we reach more than 100 °C. At 75 °C only about 85 g of KBr is dissolved.

"if you mix 120 g of NaClO3 in 100 g of water at 10 °C, approximately 30 g will not dissolve"

True. In the graph we can clearly see that at 10 °C only about 90 g is being dissolved so, the rest of the mass is still there as mass.

The theoretical probability of drawing a red card from a deck of cards is 1:2. Michael drew 20 cards and received 7 red and 13 b

Anon25 [30]

Answer and Step-by-step explanation:

Theoretical probability is expected probability of an occurrence hence the name theoretical. It is theoretical and not practical as it has not been experimented or actually become practical. Experimental probability on the other hand is probability that has been experimented- it is the result of test of probability on the actual population.

In the case above, the theoretical which is the expected probability that has not been experimented is 1/2 of getting Red cards. This probability is theoretical and therefore may change when tested. Hence the different result of 7 Red and 13 blacks with 20 cards picked when experimented
