One math student, John, can solve 6 math problems in 20 minutes while another student, Juaquine, can solve the same 6 math problems at a rate of 1 problem per 4 minutes. Who works faster?
1.John
2.Juaquine
Answer:
John
Step-by-step explanation:
6/20=0.3
1/4=0.25
Juaquine is solving problems at a faster rate as compared to John.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
As per the question, we can compare their rates of problem-solving by calculating the number of problems they can solve per minute.
For John, this is 6 problems / 20 minutes = 0.3 problems per minute.
For Juaquine, this is 6 problems / (4 minutes/problem) = 1.5 problems per minute.
Since Juaquine can solve 1.5 problems per minute compared to John's 0.3 problems per minute, Juaquine is solving problems at a faster rate.
Hence, Juaquine works faster as compared to John.

all real numbers
no solution
Answer:
All real numbers
Step-by-step explanation:
Answer:
C) all real numbers
Step-by-step explanation:
4(a + 3) = 12 + 4a
open the parenthesis
4*a + 3*4 = 12 + 4a
4a + 12 = 12 + 4a
subtract 4a from both sides of the equation
12 = 12
since 12 = 12 regardless of what x is the solution is all real numbers

Write the domain as an inequality!!!
Answer: [tex]x \le -1[/tex]
=================================================
Explanation:
The domain is the set of all possible x values of a function.
The largest x can get is x = -1, since this x value applies to the x coordinate of the right most point on the curve. The filled in circle indicates we include this endpoint as part of the domain.
There is no smallest x value due to the arrow showing the curve goes on forever in that direction.
We can write the domain as [tex]-\infty < x \le -1[/tex] but it's better to write [tex]x \le -1[/tex]
Put another way: the domain consists of values that are -1 or smaller.

why are 1/4 and 3/8 represented with negative numbers on the number line in the example
Answer: There's no image there, but I assume it's because they are behind the 0.
Step-by-step explanation: The range of real numbers goes from - infinity to positive infinity. The 1/4 and 3/8 that are on the number line are probably behind the 0, indicating that they are negative numbers. I don't know if what I'm saying makes sense in the context of the problem (since you didn't provide a picture).

Find the Area and Perimeter of the figure below.
6 cm
4 cm
2 cm
3 cm
Answer:
Area: 40cm^2
Perimeter:24cm
Step-by-step explanation:
Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.
Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.

3 times a number f increased by 5 squared
Answer:
3f + 5²
Step-by-step explanation:
3 times a number f means we could just put them together, aka 3f. Then increased means we can add. Next you see 5 squared. Squared means the exponent is 2, or you are multiplying the number with itself.

Box 2:
length
• width • height = (4x-1). x•x^3?
volume = 4x^5 -x
Degree of length:
Degree of width:
Degree of height:
Degree of volume:
DONE
Answer:
1.) Volume= Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is Length × Width × Height
2.) Terms in this set (4)
Measure 50 ml of water into a gradulated cylinder.
Place object in cylinder and measure the new volume.
Subtract the 50ml from the new volume.
The difference in the volume is the volume. of the object.
3.) Graduated cylinders
4.) Particles behave differently within each state of matter: solid, liquid, and gas. The particles give matter a property called mass. The mass of an object is related to the amount of material that makes up the object and how hard the object is to move. Simple experiments can show how gases have mass.
Explanation:
1.) Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
SI unit: Cubic metre
In SI base units: 1 m3
2.) If the object has an irregular shape , the volume can be measured using a displacement can . The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the spout. As the irregular object is lowered into the displacement can, the water level rises.
3.) Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).
4.) Mass is a measure of the amount of matter in an object. Mass is usually measured in grams (g) or kilograms (kg). ... An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity. Your mass on the earth and the moon are identical.
~-Long Story short, its 1 = Degree of Length
1 = Degree of Width
3 = Degree of Height That's is all summed up!-~
5 = Degree of Volume
Ⓗⓞⓟⓔ ⓣⓗⓘⓢ Ⓗⓔⓛⓟⓔⓓ❕
~
The degrees of the given dimensions are degree of length= 1 ,degree of width = 1 , degree of height= 3 , degree of volume = 5
To determine the degree of each dimension and the volume for Box 2, let's consider the expressions:
Length = (4x - 1)
Width = x
Height = x³
Volume = Length × Width × Height
Volume = (4x - 1) × x × x³
Now, let's simplify the volume expression:
Volume = (4x² - x) × x³
Volume = 4x⁵ - x⁴
Now, let's find the degrees of each dimension and the volume:
Degree of length:
The degree of the length dimension is the highest power of x in the expression (4x - 1). The highest power of x in this expression is 1.
Degree of width:
The degree of the width dimension is the highest power of x in the expression x. The highest power of x in this expression is 1.
Degree of height:
The degree of the height dimension is the highest power of x in the expression x³. The highest power of x in this expression is 3.
Degree of volume: The degree of the volume is the highest power of x in the expression 4x⁵ - x⁴. The highest power of x in this expression is 5.
Therefore, the degrees are as follow,
Degree of length: 1
Degree of width: 1
Degree of height: 3
Degree of volume: 5
