3. Determine the final price of purchasing a bouquet of flowers at $12.99 by first applying a coupon of 12% and then adding the sales tax of 13%.
Answer:‘12.92
Step-by-step explanation:
Answer:
Step-by-step explanation:
$12.99
applying coupon
[tex]12.99(1-12\%) = 12.99*88\% = 11.4312\\11.4312 * (1+13\%) = 12.917=12.92[/tex]
A type of fish for your aquarium costs $4 each. You can spend at most $36. How many fish can you buy? Write an inequality to model the problem? Then solve the inequality to find the number of fish.
Answer:
9 fish
Step-by-step explanation:
If each fish costs 4 dollars, and we can spend at most 36 dollars, we can find out that we can buy 9 fish by dividing 36/4, which gives you the answer of 9.
We can model this problem by doing
4x = 36
Divide by 4 on both sides to isolate the x
x = 9
Answer:
4x ≤ 36
x ≤ 9
9 fish maximum

Answer:
The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. To find the slope, use the distance formula. The distance formula is Y2-Y1/X2-X1. You can use any two points on the graph but I will use (0,4) and (3,6).
6-4/3-0
2/3
The slope is 2/3. To find the y-intercept, look at the graph and find the where the line crosses the y-axis. The y-intercept in 4. So, the equation of this line is y=2/3x+4.
:)
Answer:
[tex]y=\boxed{\dfrac{2}{3}}\:\:x+\boxed{4}[/tex]
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y = mx + b[/tex]
where:
m is the slopeb is the y-interceptTo find the slope of the given line, define two points on the line:
[tex](x_1,y_1)=(-6,0)[/tex][tex](x_2,y_2)=(0,4)[/tex]Substitute the two defined points into the slope formula and solve for m:
[tex]\implies \textsf{slope}\:(m)=\dfrac{4-0}{0-(-6)}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]
The y-intercept is y-value of the point at which the lines crosses the y-axis. From inspection of the graph, the y-intercept is 4.
Therefore, substitute the found slope and y-intercept into the slope-intercept formula to create the equation of the given line:
[tex]\implies y=\dfrac{2}{3}x+4[/tex]

The graph of a line is shown on the grid below.
Which equation best represents the graph of the line? (picture below)
A. y= 3x-2
B. y= -3x-2 (negative 3)
C. y= -3x+2 (this has a negative 3)
D. y= 3x+2
Answer:
C. y=-3x+2
Step-by-step explanation:
Looking at the graph, we see that the line intercepts the y axis at 2 and is decreasing as x increases.
The formula for a linear equation is y=mx+b
where b is the y intercept, which in this case is 2
since the y values decreases as x increases, m must be negative
35% of the birds in a sanctuary are hummingbirds. If there are 420 birds in the sanctuary
now, how many are hummingbirds?
HELP PLEASE ASAP
Answer:
147 hummingbirds are in the sanctuary.
Step-by-step explanation:
The answer can be found using the given percentage. Stating that 35% of the birds in the sanctuary are hummingbirds means that the amount of hummingbirds is 0.35 times the total amount of birds.
[tex]420 \: \times \: 0.35 \: = 147[/tex]
Percentages can always be converted to a decimal number:
(1% = 0.01 ; 10% = 0.10 ; 100% = 1.00; etc.)

(2.1x + 2.6) − (-5x − 4)
Answer:
7.1x + 6.6
Step-by-step explanation:
In order to subtract these two polynomials, you first have to change all the signs in the second parenthesis. Now you should have:
(2.1x + 2.6) - (5x + 4).
Next if you are subtracting vertically (it's easier this way, if you do) line up the like terms, like so⤵⤵⤵:
2.1x + 2.6
+ 5x + 4
7.1x + 6.6

ALGEBRAIC PROOF!!!! PLS HELP!!! The area of a rectangular blanket is 20 square feet. The blanket's length is (2x + 1) ft and the blanket's width is 2x ft. find the dimensions of the blanket. provide justification for each step.
Answer:
Length: 5 ft; width: 4 ft.
Step-by-step explanation:
A = LW formula for area of rectangle
(2x + 1)(2x) = 20 substitute length, width, and area into formula
4x² + 2x - 20 = 0 use the distributive property to multiply out left side
2x² + x - 10 = 0 divide both sides of equation by 2
(2x + 5)(x - 2) = 0 factor out trinomial
2x + 5 = 0 or x - 2 = 0 use zero product rule to solve for x
2x = -5 or x = 2 subtract 5 from both sides; add 2 to both sides
x = -5/2 or x = 2
We discard x = -5/2 since it would give negative length and width, and the length and width cannot be negative.
Length: 2x + 1 = 2(2) + 1 = 5
Width: 2x = 2(2) = 4
Length: 5 ft; width: 4 ft.

Write an explicit formula for the sequence
Answer:
[tex]u_{n}[/tex] = - 5.6n + 3.2
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]u_{n}[/tex] = u₁ + (n - 1)d
where u₁ is the first term and d the common difference
To find u₁ use the given recursive formula
u₁ = u₀ - 5.6 = 3.2 - 5.6 = - 2.4
from the recursive formula d = - 5.6 , then explicit formula is
[tex]u_{n}[/tex] = - 2.4 - 5.6(n - 1) = - 2.4 - 5.6n + 5.6 = - 5.6n + 3.2

What is the least common denominator? LCD in math
The LCD of 1/2 and 1/3 is 6, because LCM(2, 3) = 6;
Knowing the LCD, you can find equivalent fractions to yours 1/2 and 1/3, with the denominator equal to found LCD:
Answer:
12.
Step-by-step explanation:
One way to find the LCD is from the prime factors:
4 = 2*2
6 = 2*3
One '2' occurs in both sets, so we only include one of these 2's, so the LCD
= 2*2*3
= 12.
