Answer:

7.25

Step-by-step explanation:

Given :

___________ Sample size __ sample mean

Treatment 1 ____ 5 _______ 4

Treatment 2 ____ 10 ______ 8

Treatment 3 ____ 5 _______ 9

Sample size = (5 + 10 + 5). = 20

Overall mean = ((5*4). + (10*8) + (5*9)) / 20

Overall mean = (20 + 80 + 45) / 20

= 145 / 20

= 7.25

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

Answer: They can form one triangle.

Step-by-step explanation: Since all triangle must have 180 degrees, there’s only one set of degrees that sum up to 180.

28+51+101=180

I’m sorry, but the feet/centimeters part you have to solve on your own. Remember, this is a learning community! No stress :) I can guarantee you won’t get it wrong though.

There’s many different triangles, and I’m sure from these feet/centimeters you can make at least one of the listed: Scalene (none of the sides are equal), isosceles (only 2 sides are equal) or equilateral triangle (all sides are equal). There’s also right triangles (which are triangles with one right angle also known as 90 degrees) that are either isosceles or scalene or both! Try your best and remember, no stress :)

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

The area of the living room wall = The area of the rectangle

The amount of paint needed to cover one wall is 240 square feet.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

Example:

The area of a rectangle with length 2cm and width 3cm is 6cm².

We have,

A living room wall is 20 feet long, and 12 feet high.

The living room can be considered a rectangle.

Length = 20 feet

Width = 12 feet

The area of the living room wall = Area of a rectangle

Now,

Area of the living room wall.

= 20 x 12

= 240 square feet

Thus,

The amount of paint needed to cover one wall is 240 square feet.

Answer:

3/8 kg of tomatos

Step-by-step explanation:

1/4 * 2 = 2/8

2/8 + 3/8 = 5/8

1 - 5/8 = 3/8

The amount of tomatoes was left to the mother in kilograms will be 0.375 kilograms.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Mother has 1 kg of tomatoes.

She gave 1/4 to aling nena and 3/8 to aling ana.

Then the amount of tomatoes was left to the mother in kilograms will be

Let x be the amount of tomatoes.

x = 1 - 1 × 1/4 - 1 × 3/8

x = 1 - 0.25 - 0.375

x = 1 - 0.625

x = 0.375 kilograms

Answer:

This is kinda hard to answer, but i'm going to say the answer might be 14 cm squared.

Step-by-step explanation:

I don't have much info, but I can say that the 7 cm side can be split into 2 lengths of 5 cm, and 2 cm.

Using this i can do 5 times 4 to get 20, but sense it's a triangle, the triangle would be half of a square making it 10 cm for the left part of the triangle.

Using the knowledge of the left triangle, I can do 2 times 4, which equals 8, half of 8 cm is 4 cm, and now i can do the equation of 10 cm plus 4 cm equals the answer of 14 cm squared.

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

Answer:

$140,000

Step-by-step explanation:

Paso 1

Si a una persona le deben 7/9 de $ 450,000

La cantidad que se le debe a la persona se calcula como:

7/9 × $ 450,000

= $ 350,000

Paso 2

Solo se cancela 3/5 de esa deuda.

El monto de la deuda que se cancela se calcula como:

3/5 × $ 350,000

= $ 210,000

Paso 3

Por lo tanto, la cantidad de dinero que debe se calcula como:

$ 350,000 - $ 210,000

= $ 140,000

Answer:

Arc ABC = 250°

Step-by-step explanation:

m<AOB = 110° (given)

Based on the central angle theorem, central angle m<AOB equals the intercepted arc AB

Therefore,

m<AOB = measure of arc AB = 110°

Thus:

Arc ABC = 360° - arc AB (Full circle = 360°)

Arc ABC = 360° - 110°

Arc ABC = 250°

Answer:

Get a ruler

Step-by-step explanation:

I can't really answer this because it's a measuring problem.

But I'll walk you through it.

First, grab your ruler. Once you have it, you're gonna measure the icon, so the  square picture. Make sure you measure it in centimeters (cm). Measure EACH side. Once you have the measurement of each sides, add them up to get your perimeter. The perimeter will always be length + width + length + width.

To find the area, take your length and your width and multiply them together.

For the second problem, you're going to take your measured side and multiply EACH of them by 2.5. The scale 1 cm = 2.5 mm means that for every represented centimeter in the image, the actual image is 2.5 mm. Once you have multiplied each sides by 2.5, you're going to repeat the steps above to get the perimeter and the area.

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.
