1. Leslie visits a local department store in order to purchase summer clothes. The
price of the dress is $40. The dress is marked up 25%. What is the selling price of
the dress?
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50

Answer:
a) x = {-1, 3, 4}
b) (0.472, 13.128)
c) (3.528, -1.128)
d) x < 0.472 U x > 3.528
e) 0.472 < x < 3.528
Step-by-step explanation:
This is a cubic (odd degree) function with a positive leading coefficient, so it will be increasing until the first turning point, and after the last turning point. It will be decreasing between the turning points.
a) A graph shows the zeros to be x = -1, x = 3, x = 4.
b) A graph shows the local maximum to be approximately (0.472, 13.128). The x-coordinate of this point is exactly 2-√(7/3).
c) The local minimum is about (3.528, -1.128). Its x-coordinate is exactly 2+√(7/3).
d) As stated above, the increasing intervals are (-∞, 0.428) ∪ (3.528, ∞).
e) The decreasing interval is (0.428, 3.528).

Additional comments
The sum of odd-degree term coefficients is the same as the sum of coefficients of even-degree terms, so you know one of the roots is -1. Factoring that out gives the quadratic x^2 -7x +12 = (x -3)(x -4), so the other two roots are 3 and 4.
The derivative is 3x^2 -12x +5 = 3(x -2)^2 -7, so its roots (turning points of f(x)) are 2±√(7/3).
I find a graphing calculator can show me the roots and turning points easily.

Need help please I'm not sure if I'm right
Answer:
58
Step-by-step explanation:
The angles inside a triangle always sum to 180°. We already have a 32° angle and a 90° - totalling 122° - and when we add x°, we'd like the sum to be 180°. So x must be 180 - 122 = 58.
Answer:
58
Step-by-step explanation:
The total should be 180 degrees. We know the the top angle is 32 degrees and the bottom left is 90 degrees because it has a square there. So 32+90=122. If we subtract 122 from 180 we are left with 58 degrees so x=58

Henry has 96 marbles. He is packing containers with 8 marbles in each container. How many containers, c, does Henry need to pack all the marbles?
96 − c = 8
96 = 8 x c
c = 96 + 8
8 ÷ c = 96
On a snowy winters eve two candles are lit at the exact same time. A 18-inch candle and a 21-inch candle are lit at the exact same time. The 18-inch candle burns 2 inches every hour. The 21-inch candle burns 3 inches every hour. Create a system of equations using the information
Answer:
y=21-3x and y=18-2x
Step-by-step explanation:
Ok, so we have candle A, which is 21 inches and burns 3 inches every hour. in slope-intercept form, the hours would be the x, the 21 is our y intercept. So the first equatio would be y=-3x+21 (negative slope, because the height of the candle is going down). Candle b, which is 18 inches, burns away 2 inches each hour. We can make -2 the slope (negative 2, since the candle is being burned away, not being added to), and the 18 our y intercept. So the two equations would be
y=21-3x
and
y=18-2x

A. (1,-11)
B. (3,-4)
C. (1,11)
D. (0,0)
E. (-2,3)
O F. (2,9)
Answer:
(3, -4)
Step.
The coordinates of the point which lies on the equation is A ( 3 , -4 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
y + 4 = 4 ( x - 3 ) be equation (1)
when x = 3 and and y = -4
Substituting the values of x and y in the equation , we get
-4 + 4 = 4 ( 3 - 3 )
0 = 4 ( 0 )
0 = 0
Therefore , the point A ( 3 , -4 ) lies in the equation
Hence , the coordinates of the point is A ( 3 , -4 )

Estimation on a scale drawing of a fence, 3.75 inches represent 24 feet . what. is the actual length of a second fence is 2.8 inches in the drawing?
The exact length of the second fence is __ feet.
Answer: 17.92 feet
Step-by-step explanation:
From the question, we are informed that the estimation on a scale drawing of a fence is that 3.75 inches = 24 feet.
Based on the above, 1 inch will be:
= 24/3.75
= 6.4 feet
Therefore, the actual length of a second fence that is 2.8 inches in the drawing will be:
= 6.4 × 2.8
= 17.92 feet

1. A slice is being made to a cube. For each slice—
• Describe the two-dimensional figure resulting from the described slice. Use the specific name when possible.
• Determine whether a different slice can produce a congruent two-dimensional figure. If so, describe or sketch an example of the slice. If not, explain why not.
(a) a slice parallel to the base
(b) a slice that contains and
(c) a slice that contains and vertex F
(a.) A slice parallel to the base would result in two rectangular prisms, as opposed to a cube now. These two rectangular prisms would be congruent to each other as it is a perfect slice through the middle.
(b) A slice that contains and AE and DH will make a slanted cube, meaning it will turn into a cubic pyramid.
(c.) A slice that will contain and vertex F will make the cut the figure in half going slanted. They will technically be congruent, although there is no name for this figure.
