Answer:
A. 40.7%
Step-by-step explanation:
The selling price for a $5 profit will be ...
$12.75 +5.00 = $17.75
From $29.95, this represents a change of ...
(17.75 -29.95)/29.95 × 100%
= -12.20/29.95 × 100% ≈ -40.7346%

Answer:
[tex]\frac{1}{cos^2a }= tan^2 a[/tex]
Step-by-step explanation:
Explanation:-
Given sin²a + cos²a = 1
and
[tex]\frac{1}{cos^{2} a} \\= \frac{sin^2a+cos^2a}{cos^2a} \\ \\\\ = \frac{sin^2a}{cos^2a} +\frac{cos^2a}{cos^2a}[/tex]

the radius of a circle is 3 cm. Find it's area in terms of pi. 28.27 cm2 is wrong
Answer:
9[tex]\pi[/tex]
Step-by-step explanation:
The reason why that is wrong is because it says in terms o pi which means you do NOT multiply pi by the radius squared.
EQUATION FOR AREA OF A CIRCLE: [tex]\pi r^{2}[/tex]
When you put it all together you get: [tex]\pi * 3^{2}[/tex] which equals [tex]9\pi[/tex]
DO NOT MULTIPLY 9 AND PI. IT'S JUST 9[tex]\pi[/tex]

0.25*16=4
x=4.
select the equation represented by the graph
Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1

A store is having a sale on walnuts and chocolate chips. For 4 pounds of walnuts and 8 pounds of chocolate chips, the total cost is $25. For 2 pounds of walnuts and 3 pounds of chocolate chips, the total cost is $10. Find the cost for each pound of walnuts and each pound of chocolate chips.
Answer:
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
Step-by-step explanation:
Let,
x be the price per pound of walnuts
y be the price per pound of chocolate chips
According to given statement,
4x+8y=25 Eqn 1
2x+3y=10 Eqn 2
Multiplying Eqn 2 by 2
2(2x+3y=10)
4x+6y=20 Eqn 3
Subtracting Eqn 3 from Eqn 1
(4x+8y)-(4x+6y)=25-20
4x+8y-4x-6y=5
2y=5
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{5}{2}\\y=2.50[/tex]
Putting y=2.50 in Eqn 2
2x+3(2.50)=10
2x+7.50=10
2x=10-7.50
2x=2.50
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2.50}{2}\\x=1.25[/tex]
Hence,
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

a bakery uses flour at a rate of 1/3 pounds each minute. at approximately what rate does the bakery use flour, in pounds per day
Answer:
I'm pretty sure the bakery uses 480 pounds per day
Step-by-step explanation:
You would multiply 1/3 by 60, which is 60 minutes an hour, and that gives you 20 which you would then multiply 20 by 24, which is 24 hours a day, which would then give you 480 pounds of flour per day.
Answer:
480 pounds
Step-by-step explanation:
because 1/3 times 60 is 20 and that is 20 pound /a hour then multiply it by 24
because there are 24 hours a day

The length of segment EF is 8 units, the length of segment ED is 10 units, and the length of segment EA is 13.33 units. Find the length of FA Explain or show your reasoning,
Answer:
5.33 unit
Step-by-step explanation:
logically FA = EA - EF = 13.33-8 = 5.33 units
Since, E, F and A all lie on the same line EA . The information ED= units is redundant. Therefore we can say that FA= 5.33 unit
The length of FA is 5.33 units
The given parameters are:
[tex]\mathbf{EF = 8}[/tex]
[tex]\mathbf{ED = 10}[/tex]
[tex]\mathbf{EA = 13.33}[/tex]
EF and EA implies that point E is between line FA
So, the length of FA is calculated using:
[tex]\mathbf{FA = EA - EF}[/tex]
Substitute known values
[tex]\mathbf{FA = 13.33 - 8}[/tex]
Subtract
[tex]\mathbf{FA = 5.33}[/tex]
Hence, the length of FA is 5.33 units

find a number that is exactly halfway between 1 and 27
Answer:
14
Step-by-step explanation:
A number that is exactly halfway between 1 and 27 is the middle number
In other words, we want to find the median between 1 and 27
Median = (x + y) / 2
Let
x = 1
y = 27
Median = (x + y) / 2
= (1 + 27) / 2
= 28/2
= 14
Therefore, the number between 1 and 27 is 14

Answer:
The answer is y=-x+4 and y=-3x+2
Step-by-step explanation:
Answer:
y = x + 4 and y = 3x + 2
Step-by-step explanation:
Both of the lines slopes are positive, and for the equation of y = 3x + 2, the slope is 3 rather than [tex]\frac{1}{3}[/tex] because it goes up 3 then to the right 1 rather than up 1 and to the right 3.

Answer:
B.9
Step-by-step explanation:
What I did is I used ratio.
20:12
15:X
Cross multiply:15x12
Answer:180
The answer you get divided by 20.
180/20=9.
Answer:
B
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when x = 20, y = 12, then
12 = 20k ( divide both sides by 20 )
k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]
y = [tex]\frac{3}{5}[/tex] x ← equation of variation
When x = 15, then
y = [tex]\frac{3}{5}[/tex] × 15 = 9
