Step-by-step explanation:
Shopping at Savers Mart, Lisa buys her children 4 shirts and 3 pairs of pants for $85.50. She returns the next day and buys 3 shirts and 5 pairs of pants for $115.00. What is the price of each shirt and each pair of pants.
Answer:
price for one shirt
=
$
7.50
price for one pair of pants
=
$
18.50
Explanation:
Start by letting variables
x
and
y
represent the pieces of clothing from the problem.
Let
x
be the price of one shirt.
Let
y
be the price of one pair of pants.
Equation
1
:
4
x
+
3
y
=
85.50
Equation
2
:
3
x
+
5
y
=
115.00
You can solve for each variable by using elimination or substitution. However, in this case, we will use use elimination. First, we will solve for
y
, the price of each pair of pants.
To isolate for
y
, we must eliminate
x
. We can do this by making the two equations have the same
x
values. First, we find the LCM of
4
and
3
, which is
12
. Next, multiply equation
1
by
3
and equation
2
by
4
so that
4
x
and
3
x
becomes
12
x
in both equations.
Equation
1
:
4
x
+
3
y
=
85.50
3
(
4
x
+
3
y
)
=
3
(
85.50
)
12
x
+
9
y
=
256.50
Equation
2
:
3
x
+
5
y
=
115.00
4
(
3
x
+
5
y
)
=
4
(
115.00
)
12
x
+
20
y
=
460.00
Now that we have two equations with
12
x
, we can subtract equation
2
from equation
1
to solve for
y
.
12
x
+
9
y
=
256.50
12
x
+
20
y
=
460.00
−
11
y
=
−
203.50
y
=
18.50
⇒
price for one pair of pants
Now that we know that a pair of pants is
$
18.50
, we can substitute this value into either equation
1
or
2
to find price for one shirt. In this case, we will choose equation
1
.
4
x
+
3
y
=
85.50
4
x
+
3
(
18.50
)
=
85.50
4
x
+
55.5
=
85.50
4
x
=
28
x
=
7.50
⇒
price for one shirt
∴
, the price for one shirt is
$
7.50
and the price for one pair of pants is
$
18.50
.

Answer:
21.4
Step-by-step explanation:
We can solve for x using trigonometry
Here are the Trigonometric Ratios
Remember SOH CAH TOA
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent
We are given the measure of ∠T ( 72° )
We are also given the adjacent side length (6.6) ( Adjacent = the side length that is not the hypotenuse nor the opposite side length )
And we need to find the hypotenuse ( longest side length )
We this information we can use the trigonometric ratio Cosine to solve for x
That being said we want to set up an equation
(remember cosine = adjacent over hypotenuse )
[tex]cos(72)=\frac{6.6}{x}[/tex]
Now we solve for x
We can't get rid of the 6.6 itself so we want to multiply each side by x
now we have [tex]xcos(72)=6.6[/tex]
Step 2 divide each side by cos(72)
[tex]\frac{xcos(72)}{cos(72)} =x\\\frac{6.6}{cos(72)} \\x=\frac{6.6}{cos(72)}\\cos(72)=0.3090169944\\\frac{6.6}{0.3090169944} =21.35804865\\[/tex]
We're left with x = 21.35804865
Finally we want to round to the nearest tenth of a foot and we get that x = 21.4
Find the length and width of a similar rectangular screen if the length is 5 meters more than 6 times its width, and the viewable area is 5,550 square meters.
Answer:185 m , 60 m
Step-by-step explanation:
Given
Length is 5 m more than 6 times its width
Suppose width is [tex]x[/tex]
So, length is given by [tex]6x+5[/tex]
The area is given by [tex]l\times b[/tex]
Put values of length and width
[tex]\Rightarrow (6x+5)x=5550\\\Rightarrow 6x^2+5x-5550=0\\[/tex]
On solving the quadratic equation, we get [tex]x=30[/tex]
Length is [tex]6\times 30+5=185\ m[/tex]
Width is [tex]x=30\ m[/tex]

A school ordered 32 orange shirts, 29 blue shirts, and 34 green shirts. The shirts are being divided equally among 6 classrooms. If each classroom gets the same number of shirts, how many shirts will be left over?
A.
2
B.
4
C.
5
D.
3
Answer: D
Step-to-step explanation:
Answer:
C
Step-by-step explanation:
The orange shirts will have 32/6 = 5 with 2 left over
The blue shirts will have 29/6 = 4 with 5 left over
The green shirts will have 34/6 = 5 with 4 left over
The left overs are 2 + 5 + 4 = 11 but I have divided the colors equally. If color does not matter then the total number of shirts = 32 + 29 + 34
The total number of shirts is 95
95/6 = 15 with a remainder of 5
So 5 shirts will be left over.

Step-by-step explanation:
A brick wall will be shaped like a rectangular prism. The wall needs to be 3ft tall and the builders have enough bricks for the wall to have a volume of 330 cubic feet. What tool can be used to find possible dimensions for the base of the wall?
Answer:
For a rectangular prism that has a base area B, and a height H, the volume is:
V = B*H
This is the only "tool" that we need to use in this situation.
We know that the wall needs to be 3ft tall, then H = 3ft
And we also know that we have enough bricks for a wall of a volume:
V = 330 ft^3
If we replace these two in the volume equation, we get:
330ft^3 = B*3ft
Now we can solve this for B, and thus find the volume of the base of the wall.
To do it, we just need to divide both sides by 3ft
(330 ft^3)/3ft = B*3ft/3ft
110 ft^2 = B
This means that the area of the base is 110ft^2
As the base is a rectangle of width W and length L, we must have:
110ft^2 = B = L*W
Then the possible measures of the base are given by the linear relation:
L = 110ft^2/W
Where we also need to add some trivial restrictions, like:
L > 0 ft
W > 0ft
This only means that we can not have a length or width equal to or smaller than zero, as those do not have physical sense.

a company wants to rent a tent that had a height of at least 10 feet for an outdoor show. should they rent the tent show at the right? explain.
Related diagram is attached below :
Answer:
No
Step-by-step explanation:
The height, h of the tent attached below can be obtained using Pythagoras rule, as the shape forms a right angle triangle.
Length of base , = 24 / 2 = 12 feets
Hypotenus = 15 feets
The height, h = √(hypotenus² - Base²)
h = √15² - 12²
h = √225 -144
h = √81
h = 9 feet
Tent shouldn't be rented as it is below 10 feets
