A baker can decorate one cake in
hour.
What is the total number of hours the baker needs to decorate 4 cakes?
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.
In a completely randomized design involving three treatments, the following information is provided:Treatment 1Treatment 2Treatment 3Sample Size5105Sample Mean489The overall mean for all the treatments is _______.
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

Given the equation: I + I → I2 + 35 kcal This equation shows that the formation of an iodine molecule is an A) endothermic process in which energy is absorbed B) exothermic process in which energy is released C) exothermic process in which energy is absorbed D) endothermic process in which energy is released
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.
What is an endothermic process?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.

The measure of ∠BCF is 60°, and the measure of ∠FCG is 35°. Which equation can you use to find the measure of ∠BCG?
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

Sarah was thinking of a number. Sarah subtracts 1.7 from the number and gets an answer of 14. Form an equation with x from the information.
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
Si a una persona le deben 7/9 de $450000 y sólo le cancelan 3/5 de esa deuda. ¿Cuánto dinero le quedan debiendo?
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

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.
What is a rectangle?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.

For each set of angles or sides lengths, determine whether they could form a unique triangle, more than one triangle, or no triangle.
5 cm, 10 cm, 12 cm
8 ft, 12 ft, 20 ft
40°, 50°, 80°
28°, 51°, 101°
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 :)
Mother has 1 kg of tomatoes.She gave 1/4 to aling nena and 3/8 to aling ana.How many kilograms of tomatoes was left to mother
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.
What is Algebra?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

A box contains 21 marbles of the same size. 7 of the marbles are white, 4 are black, 10 are green. If two of the marbles are randomly selected from the box, what is the probability that the first marble is white and the second is green, given that the first marble is not replaced before the second marble is selected
Answer:
7/21 x 10/20
1/3 x 1/2 = 1/6
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability of picking a white marble first = total number of white marbles / total number of marbles = 7/21
probability of picking a green marble second = total number of green marbles / total number of marbles = 10/20
7/21 x 10/20
1/3 x 1/2 = 1/6
Help! I don’t know what to do
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.
What is the area of this triangle
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.
