Answer:

A. The independent variable is the temperature of the water, and the dependent variable is the amount of sugar dissolved.

Step-by-step explanation:

Given that Eman is conducting an experiment to see how much sugar will dissolve in water as the temperature of the water is increased.

Here the variables are sugar and temperature.

Since temperature is varied first and corresponding change in sugar is measured we can say temperature is an independent variable and sugar is the dependent variable.

A. The independent variable is the temperature of the water, and the dependent variable is the amount of sugar dissolved.

In the accompanying diagram, line BD bisects acute angle ABC and line AD is parallel to line BC. What kind of triangle must tria
galina1969 [7]

Answer:

  isosceles

Step-by-step explanation:

With AD║BC, ∠ADB ≅∠DBC. The angle bisection also ensures that ∠ABD≅∠DBC. Hence the two angles ABD and ADB must be congruent to each other.

A triangle with two congruent internal angles is an isosceles triangle.

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle \frac{a}{-7} - 7 = 5<u />

<u />

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Addition Property of Equality:                    \displaystyle \frac{a}{-7} - 7 + 7 = 5 + 7
  2. [Simplify] Add:                                             \displaystyle \frac{a}{-7}= 12
  3. Multiplication Property of Equality:           \displaystyle -7 \cdot \frac{a}{-7} = 12 \cdot -7
  4. [Simplify] Multiply:                                      \displaystyle a = -84

<u>Step 3: Check</u>

<em>Plug in a into the original equation to verify it's a solution.</em>

  1. Substitute in <em>a</em>:                    \displaystyle \frac{-84}{-7} - 7 = 5
  2. [Frac] Divide:                       \displaystyle 12 - 7 = 5
  3. Subtract:                              \displaystyle 5 = 5

Here we see that 5 does indeed equal 5.

∴ a = -84 is the solution to the equation.

The surface area, A, of a cylinder is given by the formula A = 2 Trh + 2nr, where ris the radius and h is the height
lord [1]

Answer:

Area = 87.9646  sq. units  from A = 28*π  sq. units.

However I cannot see this in your answer list, since the numbers look all jumbled.  Choice A. looks close to it, since there is a 28...

Step-by-step explanation:

We have a cylinder with height h = 5

radius = 2

We want the surface area of this cylinder.

A = (circumference)*h  + 2*(pi)*r^2

A = ( 4*π)*5   + 2*π*(2^2)

A = 20π + 8π  =  28 π   square units

A = 87.9646 sq.. units
