Answer:
66% off
Step-by-step explanation:
Answer:
50% percent is $7.50
80% is 3.00
so it is a bit less then 65% but more then 60%
so it is 66% off

What are two coordinates on this graph?
Answer:
(0,5) and (6,0)
Step-by-step explanation:
which is an equation of the line parallel to 4y-7x=8 and passes through (-4,0)
Answer:
The correct option is; A. [tex]y = \dfrac{7}{4} x + 7[/tex]
Step-by-step explanation:
The given equation is 4·y - 7·x = 8
The coordinates of the point the line passes = (-4, 0)
By dividing the given equation by 4, we have;
4·y/4 - 7/4·x = 8/4
Which gives;
y - 7/4·x = 2
y = 7/4·x + 2
Which is the equation of a straight line in slope and intercept form, y = m·x + c, with the slope, m = 7/4, and the y-intercept = 2
Given that the required line is parallel to the graph of the equation, 4·y - 7·x = 8, the slopes of both equations are equal we have;
Slope of required line = 7/4, point on the line = (-4, 0), which gives the following point and slope form equation of a straight line;
y - 0 = 7/4 × (x - (-4))
y = 7/4·x + 7/4 × 4 = 7/4·x + 7
The equation of the line is therefore;
y = 7/4·x + 7
Find the slope and a point on the line. y-9=-1/3(x-4)
Answer:
slope- -1/3
a point: (0, [tex]\frac{31}{3}[/tex])
Step-by-step explanation:
y-9= -1/3(x-4)
y-9= -1/3x+4/3
y= -1/3x+31/3
to find a point:
y= -1/3(0)+31/3
y=31/3
(this happens when x= 0, so the point is (0,31/3)
Answer:
m=-1/3
Point: (4,9)

graph the function -4x + 3y = 15
The table of values represents a linear function g(x), where x is the number of days that have passed and g(x) is the balance in the bank account:
x g(x)
0 $600
3 $720
6 $840
Part D: What is the balance in the bank account after 7 days? (2 points)
Answer:
880
Step-by-step explanation: Every three days the balance increases by 120 so you would divide 120 by 3 to get 40. This would mean that the balance increases by 40 everyday so after seven days the balance would be 880
You were given a Starbucks gift card for your birthday. One day, you used the gift card to order 3 drinks that cost $5.20 each. When you looked at your receipt, you noticed that there was a remaining balance of $26.00 on the gift card.
Write an equation in point-slope form that represents the total balance left on the gift card, y, in terms of the number of drinks ordered, x.
Answer:
The card had 41.60 originally
Step-by-step explanation:
3 x 5.20 = 15.60
15.60 + 26.00 = 41.60

Answer:

Step-by-step explanation:
2/5+6/10
What is the answer
We have to make sure the denominators are equal.
10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.
Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10
Now the equation is 4/10 + 6/10
Since our denominators match, we can add the numerators.
4 + 6 = 10
That gives us the sum, which is 10/10 aka 1 whole
your welcome :) (btw can u please give brainly?)
Answer:
2/5 + 6/10 = 1
Step-by-step explanation:
first let’s change 2/5 so it has the same denominator as 6/10.
2/5 * 2/2 = 4/10
now add
4/10 + 6/10 = 1

Answer:
a = 6
b = 3
c = 2
Step-by-step explanation:
Since n(P) = a+b = 9
and n(Q) = b+c = 5
and b is given to be 3
a and b follow easily.
a is 9-b = 9-3 = 6
c is 5-b = 5-3 = 2
The length of the day in Lagos, Nigeria (in minutes), ttt days since the beginning of the year can be estimated by this formula: \qquad L(t) = 727+22\sin \left(\dfrac{2\pi (t - 80.75)}{365}\right)L(t)=727+22sin( 365 2π(t−80.75) )L, left parenthesis, t, right parenthesis, equals, 727, plus, 22, sine, left parenthesis, start fraction, 2, pi, left parenthesis, t, minus, 80, point, 75, right parenthesis, divided by, 365, end fraction, right parenthesis. When is the longest day of the year? Give an exact answer.
Answer:
The longest day of the year is day 172
Step-by-step explanation:
Since the length of day is L(t)=727+22sin[2π(t−80.75)/365], the maximum length of day is obtained when sin[2π(t−80.75)/365] is at its maximum value which is 1. So. sin[2π(t−80.75)/365] = 1
We now solve this to find the day at which this maximum value occurs.
sin[2π(t−80.75)/365] = 1
[2π(t−80.75)/365] = sin⁻¹(1)
[2π(t−80.75)/365] = π/2
dividing both sides by 2π/365, we have
[2π(t−80.75)/365] ÷ 2π/365 = π/2 ÷ 2π/365
t−80.75 = 365/4
t−80.75 = 91.25
t = 91.25 + 80.75
t = 172
The longest day of the year is day 172
Answer:
172
Step-by-step explanation:
Keep in mind, that when graphed one of the "tallest" points is 172,749. Using this, you'll find that 172 is the tallest

Answer:
4c² + 11cd + 5d
Step-by-step explanation:
To add monomials, you have to look at the variables that are accompanied by their coefficients. In the given problem, (–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd), you can combine both cd ut nt cd and c² and cd and d and d and c² because they have different variables.
(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)
(-4c² + 8c²) + (7cd + 4cd) + (8d - 3d)

$7. Which expression below models Quinton's net proceeds algebraically?
oyn(1.01d - 7).
(1.01nd + 7) - Y
y - 1.01(nd - 7)
y (1.01nd + 7)
Answer:
y - (1.01nd + 7)
Step-by-step explanation:
Quinton bought n number of shares for d dollars and paid a 1% commission. It means he bought [tex]\dfrac{1}{100}nd=0.01nd[/tex]
He sold the stock for y dollars and paid a flat fee of $7. It means he sold y-7.
We need to find Quinton's net proceeds algebraically. It will be given as :
[tex]y-7-0.01nd\\\\=y-(0.01nd+7)[/tex]
Hence, the correct option is (d) i.e. y - (1.01nd + 7)
The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of π? A cone with a right triangle formed from its dimensions; the value of the height is h, and the value of the slant height is y; the height x and the radius form a right angle at the center of the cone.
Answer:
142.1π in³
Step-by-step explanation:
Given that:
The radius (r) = 7 in
The slant height (y) = 25 in
Then the height (x) can be determined by using the Pythagoras rule:
y² = x² + r²
25² = x² + 7²
125 = x² + 49
125 - 49 = x²
x² = 76
x = √76
x = 8.7
The formula for the volume of a cone is;
= 1/3 πr²h
where;
height(h) is calculated as "x" from above = 8.7
Then;
= 1/3 × π × (7 in)² × 8.7 in
= 142.1π in³

The bus drives 66 km at an average speed of 24 km/h. How long does the journey take?
Answer:
2.75 hours
Step-by-step explanation:
Speed is 24km per hour ([tex]\frac{24km}{1hour}[/tex]), and the bus covered 66km.
We need to get a value of km with the rate (24/1) and distance (66) given.
We get: [tex]\frac{1hour}{24km} *66km[/tex].
The km cancel out, leaving us with 66/24 hours, or 2.75 hours.

What percent of 40 is 20?
Answer:
8
Step-by-step explanation:
When doing these types of problems, we convert the percent to a decimal. In this case,
40%=0.4
0.4*20=8
Answer:
200%
Step-by-step explanation:
20 = 100% (in this case)
40 = 200% (because you multiply both sides to get 40)
Therefore, 40 is 200% of 20.
While Justin is in training he has to drink 500 ml of water per day. How many liters will that be for one week?
Answer:
3.5 Liters
Step-by-step explanation:
Since 500 ml is equal to 0.5 liters and there are 7 days in a single week you just need to multiple the number of liters (0.5) by the 7 days to get a total of 3.5 liters
