Answer:

x - 1.7 = 14

Step-by-step explanation:

Sarah thought of a number: x

Then she subtracted 1.7 FROM it: x - 1.7

and gets an answer if 14: x - 1.7 = 14

so the equation is x - 1.7 = 14

Answer:

4 hours

Step-by-step explanation:

It takes one hour to make one cake, so we can put that as a ratio of 1:1.

4 cakes means you multiplied one side by 4, as it is 4 cakes and not one, so you multiply the time by 4 too.

4 hours

Answer:

4 hours is needed for the baker to decorate 4 cakes.

Answer: 60%

If I’m understanding this problem correctly (I believe it wants me to isolate the group), we’re taking 27% (0.27) of the total men who answered the survey which equated to 45% (0.45)

First we’ll change 0.27 and 0.45 to 27 and 45. So, if 45 is our maximum, then if we divide 27 by 45, we’ll get the value 0.6–> if we multiply that by 100, we’ll get 60%.

Thus, 60% of men within that gender group preferred suspense movies.

Answer:

D is the one

The value of the constant in the equation is,

⇒ C = 0.8

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The graph is shown in image.

Now,

Take a point on the graph;

⇒ (0.8, 1)

Here, Height equation:

⇒ H = C / W

In which H is the height, C is the constant and W is the width.

Now, Choosing a point and finding the constant:

We choose a point given in the graphic, I will choose (0.8,1), which means that when W = 0.8, H = 1.

Hence, We use this to find the constant.

So, We get;

⇒ H = C / W

⇒ 1 = C / 0.8

⇒ C = 0.8

Thus, The value of the constant in the equation is,

⇒ C = 0.8

Answer:

x =  ∠BCF+ ∠FCG

Step-by-step explanation:

According to the given measure, we can say that, line Fc bisects  ∠BCF and  ∠FCG and the sum of  ∠BCF and  ∠FCG is  ∠BCG. Mathematically;

∠BCF+ ∠FCG =  ∠BCG

Given

∠BCG = 60degrees

∠FCG = 35degrees

Let x be equal to  ∠BCG

Hence the required equation will be;

∠BCF+ ∠FCG =x

Swap sides

x =  ∠BCF+ ∠FCG

Given:

[tex]L=2\dfrac{1}{2}[/tex] ft and [tex]W=3\dfrac{2}{5}[/tex] ft.

[tex]P=2L+2W[/tex]

To find:

The value of P.

Solution:

We have,

[tex]P=2L+2W[/tex]

Substituting [tex]L=2\dfrac{1}{2}[/tex] and [tex]W=3\dfrac{2}{5}[/tex], we get

[tex]P=2\times 2\dfrac{1}{2}+2\times 3\dfrac{2}{5}[/tex]

[tex]P=2\times \dfrac{2(2)+1}{2}+2\times \dfrac{3(5)+2}{5}[/tex]

[tex]P=2\times \dfrac{5}{2}+2\times \dfrac{17}{5}[/tex]

[tex]P=5+\dfrac{34}{5}[/tex]

Taking LCM, we get

[tex]P=\dfrac{5(5)+34}{5}[/tex]

[tex]P=\dfrac{25+34}{5}[/tex]

[tex]P=\dfrac{59}{5}[/tex]

[tex]P=11\dfrac{4}{5}[/tex]

Therefore, the value of P is [tex]11\dfrac{4}{5}[/tex] ft.

Answer:

A) endothermic process in which energy is absorbed

Step-by-step explanation:

A thermochemical reaction equation is a chemical reaction equation in which the enthalpy of reaction is written after the symbols of reactants and products.

The importance of thermochemical reaction equations is that they show us whether energy was absorbed or evolved in a reaction as well as the magnitude of energy absorbed or evolved.

When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. When the enthalpy of reaction is negative, the reaction is exothermic and energy is evolved or released.

The enthalpy of the reaction  I + I → I2 + 35 kcal is positive hence the reaction is an endothermic process in which energy is absorbed.

The equation shows that the formation of an iodine molecule is an A. endothermic process in which energy is absorbed.

It should be noted that an endothermic process is where heat is transferred from the surroundings to the systems. In this case, the system has gained heat from the surroundings.

The change in enthalpy, delta H is positive for an endothermic process. When the enthalpy of reaction is positive, the reaction is endothermic and energy is absorbed. The enthalpy of the reaction is positive as illustrated in this case.
