Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate (Below).
Machine A covers 5/8 square feet in 1/4 hour or Machine B covers 2/3 square feet in 1/5 hour.
Answer:
Unit Rate of Machine A = 2.5 square feet per hour
Unit Rate of Machine B = 3.333 square feet per hour.
The unit rate of Machine B is greater than unit rate of machine A.
Step-by-step explanation:
The unit rates for both machines need to be calculated first.
The unit rate will be calculated as:
[tex]Unit\ rate = \frac{Area\ covered}{Time}[/tex]
For Machine A:
Area Covered = 5/8
Time = 1/4
The unit rate will be:
[tex]U_A = \frac{\frac{5}{8} }{\frac{1}{4} } \\Using\ rule => \frac{\frac{a}{b} }{\frac{c}{d} } = \frac{a}{b} * \frac{d}{c}\\=\frac{5}{8} * 4 \\= \frac{5}{2} = 2.5\ square\ feet\ per\ hour[/tex]
For Machine B:
Area Covered = 2/3
Time = 1/5
[tex]U_B = \frac{\frac{2}{3}}{\frac{1}{5}}\\= \frac{2}{3} * \frac{5}\\= \frac{10}{3}\\= 3.33...\ square\ feet\ per\ hour[/tex]
As it can be seen that unit rate for Machine B is greater than Unit Rate of Machine A.
Hence,
Unit Rate of Machine A = 2.5 square feet per hour
Unit Rate of Machine B = 3.333 square feet per hour.
The unit rate of Machine B is greater than unit rate of machine A.

Find the area of the figure.
Use 3.14.
Answer:
First multiple 10 x 4. Then multiple 3.14 x 25 because the radius is 5 and the area of the circle would be 3.14 x 25 then add your answer from that to 40. so add 40 plus the answer from 3.14 x 25.
Find the whole number that satisfies all of the following conditions it is a whole number between 1 and 100 inclusive 10% of the number is greater than 1 but less than 7 1/3 of the number is a square number the number is not a multiple of 6
Answer:
Step-by-step explanation:
The question is a little unclear in this statement.
10% of the number is greater than 1 but less than 7 1/3 . Do you mean 7 1/3%
List all the perfect squares between 1 and 100
1 4 9 16 25 36 49 64 81 and 100
The number is not a multiple of 6 which lets out 36
The number is greater than one because 10% of the number is greater than 1.
7.33333% = 7.333 / 100 * N
That lets out 100 which 7.3333% = 7.3333
So what do we have left?
4 9 16 25 49 64 81
That's as far as I can get you. Perhaps if you clarify what is unclear, we might be able to take it further. Leave a statement, and I will revise my answer.
Janet can plant nine feet of carrots in 15 minutes while her daughter Amy can plant 17 feet of carrots in half an hour.
Who plants carrots more quickly? Show work
Answer:
Step-by-step explanation:
In order to find who is more efficient at planting carrots, we want to put both ratios in terms of the same amount of time.
For simplicity, lets see how many carrots each can make in 1 hour.
[tex]Janet:\\9ft \: in \: 15 \:minutes[/tex]
[tex]\frac{9ft}{15min} = \frac{xft}{60min}\\x = \frac{60*9}{15} = 36[/tex]
Janet can plant 36 feet of carrots in one hour
[tex]Amy:\\\frac{17ft}{30min} = \frac{xft}{60min}\\x = \frac{17*60}{30} = 34[/tex]
Amy can plant 34 feet of carrots in one hour
So, Janet can plant carrots more quickly

What are the domain and range of f(x)=19 ?
a
Domain: All real numbers greater than or equal to 19 Range: All real numbers
b
Domain: {19} Range: All real numbers
c
Domain: All real numbers Range: All real numbers greater than or equal to 19
d
Domain: All real numbers Range: {19}
Answer:
Q1 d, Q2 c, Q3 d
Step-by-step explanation:
Q1
g(x)=-3x+1
g(x)=16 means that
-3x+1=16 subtract 1 from both sides
-3x=16-1 combine like terms and divide both sides by -3
x=-15/3=-5
Q2
g(x)=3x²+4x-1
g(2) means that x=2 so substitute
g(2)=3*2²+4*2-1=12+8-1=19
Q3
domain are the x values
range are the y values

What is the slope?????
Answer:
Slope= 2/3
Step-by-step explanation:
Here are our coordinates:
x1= 20
y1= 60
x2= 50
y2= 80
Now we use the slope formula-- y2-y1/x2-x1.
Now we plug in the numbers!
80-60= 20
=20/30
50-20= 30
Now we simplify: 20/10= 2
30/10=3
Thus your answer: 2/3
Each tire on your bicycle has a diameter of 26 inches. About how far will you travel when the tires make on complete revolution?
Answer:
one revolution will be the circumference of the tire, so multiply pi (3.1416) times the diameter (26 in.), to get 81.68 in.

Answer:
x = 10
Step-by-step explanation:
First look at the big overall triangle.
It has a right angle and another angle of 44; therefore the missing angle is (since the sum of angles inside a triangle is 180)
180 - 90 - 44 = missing angle
missing angle (top) = 46; now the angle of a straight line is 180 and they give you 56° which has a supplementary angle of 180 - 56 = 124°.
Now we know that the triangle that include the x has angles 46° (missing top angle), and supplementary angle of 124°. Therefore
x = 180 - 46 - 124
x = 10

PLEASE HELP :)
Answer:
[tex]The \ total \ number \ of \ distinct \ diagonals \ in \ a \ polygon \ with \ n \ sides= \dfrac{n \times (n - 3)}{2}[/tex]
Step-by-step explanation:
A diagonal is defined in geometry as a line connecting to two non adjacent vertices.
Therefore, the minimum number of sides a polygon must have in order to have a diagonal n - 3 sides as the 3 comes from the originating vertex and the other two adjacent vertices
Given that the polygon has n sides, the number of diagonals that can be drawn from each of those n sides gives the total number of diagonals as follows;
Total possible diagonals = n × (n - 3)
However, half of the diagonals drawn within the polygon are the same diagonals drawn in reverse. Therefore, the total number of distinct diagonals that can be drawn in a polygon is given as follows;
[tex]The \ total \ number \ of \ distinct \ diagonals \ in \ a \ polygon \ with \ n \ sides= \dfrac{n \times (n - 3)}{2}[/tex]
Find the slope of the ordered pair. A(4,6) B(5,8)
Answer:
The slope is 2Step-by-step explanation:
Step one:
we are required to find the slope of the given data points
A(4,6) B(5,8)
hence the x and y values correspond to
x1=4
y1=6
x2=5
y2=8
Step two:
Required is the slope which is
slope= y2-y1/x2-x1
Slope=8-6/5-4
Slope= 2/1
Hence the slope of the ordered pair is 2
is 7.2 a rational number
Step-by-step explanation:
A decimal is a number that represents a fractional part of a whole. For example, the decimal 0.25 represents 25/100. Numbers with decimals are not integers because an integer is defined as a whole number with no fractional part.
