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

Solving systems of equations by graphing. how do you do this
Answer:
Solve systems of equations by graphing
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Example
[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]
Graph the equations in a coordinate plane
The two lines intersect in (-3, -4) which is the solution to this system of equations.

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

Determine the number of terms n :
a 1 = 15, a n = 79, S n = 423
Answer:
The number of terms in the sequence is 9
Step-by-step explanation:
We want to get the number of terms
Mathematically, we have the formula for the sum of terms in an arithmetic sequence as
[tex]sn = \frac{n}{2} (a + 1)[/tex]
a represents the first terms, and i represent the last term
[tex]423 = \frac{n}{2} (15 + 79) \\ \\ 423 \times 2 = 94(n) \\ \\ 94n = 846 \\ \\ n = \frac{846}{94} \\ \\ n = 9[/tex]

Actually Welcome to the Concept of the linear equation in two variables.
So we have to form two equations to solve this.
Let the number of children be 'x' and number of adults be 'y'.
hence, we get as,
x+y = 630 ..... (1)
and also, to their total cost spending, we get as,
1.5x + 2.25y = 1170 ...... (2)
solving (1) and (2) we get as,
Number of children were = 330
and Number of Adults were = 300

Answer:
x = 26°
Step-by-step explanation:
for these triangles to be congruent m∡B must equal m∡E
m∡B = 180 - (114+23) = 43°
to find 'x': x + 17 = 43
x = 43 - 17 = 26

The diameter of a circle is 34 feet. What is the circle’s area?
Use 3.14 as pi
The radius of the circle is 17 feet. Then the area of the circle is 907.46 square feet.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be given as,
A = πr² square units
The diameter of the circle is 34 feet. Then the radius of the circle is calculated as,
r = 34 / 2
d = 17 feet
The area of the circle is calculated as,
A = πr²
A = 3.14 x 17 x 17
A = 907.46 square feet

Answer:
25/m^3
Step-by-step explanation:
(5m^2)^3 is just an expanded way of saying 125m^6. 125m^6/5m^9 is going to get you 25/m^3, as the 6 and the 9 cancel to get you 3 on the denominator, and 125/5 gets you 25.

calculate b and a
Answer:
b=61
a=14
Step-by-step explanation:
The two lines are parallel, so
b= a+47
180- (47*2)=180-94= 86
33+86=119
b=180-119=61
a=b-47
a=61-47=14
