Let [tex]s[/tex] represent the amount of sunglasses bought and [tex]t[/tex] represent the amount of shirts bought.
Scarlet bought 3 pairs of sunglasses and 2 shirts for $81. In other words:
[tex]3s+2t=81[/tex]
Paula bought one pair of sunglasses and five shirts for $105. In other words:
[tex]s+5t=105[/tex]
We have a system of equations and can solve it by isolating [tex]s[/tex].
[tex]s+5t=105[/tex]
[tex]s=105-5t[/tex]
Now, substitute.
[tex]3s+2t=81[/tex]
[tex]3(105-5t)+2t=81[/tex]
[tex]315-15t+2t=81[/tex]
[tex]-13t=-234[/tex]
[tex]t=18[/tex]
Now, determine [tex]s.[/tex]
[tex]s=105-5t[/tex]
[tex]s=105-5(18)[/tex]
[tex]s=15[/tex]
Thus, a pair of sunglasses is $15 and a shirt is $18.

If ABCD is a rectangle, and ABD=55, what is the value of X?
Answer:
x= 70
Step-by-step explanation:
This question needs an attachment; see attached
Given
ABD = 55
Required
Find x?
In the figure shown in the attachment, angle b and ABD are alternate interior angles;
From parallel and perpendicular line theorems; alternate interior angles are equal.
This implies that <b = 55
Also; when a rectangle is divided by two diagonals, the resulting triangles are isosceles triangles;
where 2 sides and 2 angles are equal;
This implies that <b = <c = 55
Sum of angles in a triangle = 180;
So,
<x + <b + <c = 55
x + 55 + 55 = 180
x + 110 = 180
Subtract 110 from both sides
x + 110 - 110 = 180 - 110
x = 180 - 110
x = 70

D.The player runs 6 meters forward, and then runs O meters in the opposite direction.
Answer:
A.The player runs 5 meters forward, and then runs 5 meters in the opposite direction.
Step-by-step explanation:
A.The player runs 5 meters forward, and then runs 5 meters in the opposite direction.
+5 -5 = 0 they will be at the same place they started
B.The player runs 5 meters forward, and then runs 6 meters in the opposite direction.
+5 -6 = -1 they will be 1 m behind where they started
C.The player runs 6 meters forward, and then runs 5 meters in the opposite direction.
+6 -5 = 1 they will be 1 m in front of where they started
D.The player runs 6 meters forward, and then runs O meters in the opposite direction.
+6 -0 = 6 they will be 6 meters in front of where they started
Determine the value of the missing exterior angle. options: A) 104° B) 256° C) 72° D) 92°
answer: X would equal 104
Step-by-step explanation:
you would first find the interior angle for the other 2 exterior angles this would lead for the other 2 interior angles would be 88 and 16 so you would have 180 - 176 so then you do 180- 76 to find the missing angle of X
Missing exterior angle is 104°.
What is exterior angle?Exterior angles are angles that are parallel to the inner angles of a polygon but lie on the outside of it. The measure of an exterior angle is equal to the sum of the two internal opposite angles.
Given,
In the figure
Measure of exterior angles = 92°, 164°, x°
Sum of exterior angles of triangle is 360°
92° + 164° + x° = 360°
256° + x° = 360°
x° = 360° - 256°
x° = 104°
Hence, 104° is the measure of the missing exterior angle.

A 160 ft. long wire has a resistance of 16.2. What would the resistance of 8 ft. of wire be?
Answer:
Resistance of 8 feet wire = 0.81 Ω
Step-by-step explanation:
Equation representing the relation between the resistance and length of a cylindrical shaped wire is,
R = ρ.[tex]\frac{l}{A}[/tex]
Here R = Resistance of the cylindrical wire
ρ = Resistivity of the material
l = Length of the wire
A = Cross sectional area of the wire.
If length of the wire = 160 ft
Resistance = 16.2 Ω
By substituting these values in the formula,
16.2 = ρ.[tex]\frac{160}{A}[/tex]
ρ = [tex]\frac{16.2\times A}{160}[/tex]
Similarly, if length of the same wire = 8 ft
From the given formula,
R = ρ.[tex]\frac{8}{A}[/tex]
R = [tex]\frac{16.2\times A}{160}\times \frac{8}{A}[/tex]
= 0.81 Ω
Therefore, resistance of 8 feet wire will be 0.82 Ω.

the object on the right is made from a square-based pyramid joined to a cuboid.
the base of the cuboid and the base of the pyramid are both squares of side 6cm.
the bright of the cuboid is 9cm and the total height of the object is 17cm.
the total mass of the object is 970g.
the cuboid is made from wood with density 0.68g/cm^3
the pyramid is made from steel.
calculate the density of the steel in g/cm^3.
you must show your working.
Answer:
Density of steel = 80.73 gm/[tex]cm^3[/tex]
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:
[tex]V_{Cuboid} = l \times w \times h[/tex]
[tex]V_{Cuboid} = 6 \times 6 \times 9\\\Rightarrow V_{Cuboid} = 324\ cm^3[/tex]
Density of Wood , [tex]D_{Cuboid}[/tex]= 0.68g/[tex]cm^3[/tex]
We know that formula of Density is:
[tex]Density = \dfrac{Weight}{Volume}[/tex]
[tex]D_{Cuboid} = \dfrac{W_{Cuboid}}{V_{Cuboid}}\\\Rightarrow W_{Cuboid} = V_{Cuboid} \times D_{Cuboid}[/tex]
Putting the values:
[tex]W_{Cuboid} = 324 \times 0.68 = 220.32\ gm[/tex]
Total weight = [tex]W_{Cuboid} + W_{Pyramid}[/tex]
970 = 220.32 [tex]+ W_{Pyramid}[/tex]
[tex]W_{Pyramid}[/tex] = 749.68 gm
Volume of pyramid is given as:
[tex]V_{Pyramid}= \dfrac{1}{3} \times \text{Area of Base} \times \text{Vertical Height}[/tex]
Base is a square with side 6 cm
[tex]V_{Pyramid}= \dfrac{1}{3} \times 6 \times 6 \times (17 -9)\\V_{Pyramid}= 96\ cm^3[/tex]
Density of Steel/Pyramid:
[tex]D_{Pyramid} = \dfrac{W_{Pyramid}}{V_{Pyramid}}\\\Rightarrow D_{Pyramid} = \dfrac{749.68}{96}\\\Rightarrow D_{Pyramid} = 80.73\ gm/cm^3[/tex]

Use the interactive to graph a line with the given points: (–1,7) and (1,–1) The coordinates of the y-intercept of the line are.
Answer:
The y-intercept would be 6.25
Step-by-step explanation:
I found this by taking the two points and making it into a y = mx + b line.
Answer:
(0,3)
Step-by-step explanation:
We can use the slope-intercept form to find the y-intercept.
First, we need to find the slope of the line.
We are given the points (-1,7) and (1,-1).
[tex]m=\frac{rise}{run}=\frac{-1-7}{1+1}=\frac{-8}{2}=-4[/tex]
The slope is -4.
Slope-intercept is [tex]y=mx+b[/tex].
We can replace 'y' and 'x' with one of the points given, 'm' with the slope, and solve for 'b'. "B" would be the y-intercept.
I will use (-1,7):
[tex]7=-4(-1)+b\\\\7=4+b\\\\7-4=4-4+b\\\\\boxed{3=b}[/tex]
The line's equation is [tex]y=-4x+3[/tex].
Therefore, the y-intercept is '3'. The coordinates of the y-intercept is (0,3).

Step-by-step explanation:
Start by transforming the equation to your liking:
[tex]5y^2-2=3y\\5y^2-3y-2=0\\[/tex]
Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.
Now substitute those two number in place of the middle term, which is -3y like so:
[tex]5y^2-5y+2y-2 =0[/tex]
Now solve the equation in pieces... find the greatest common factor from [tex](5y^2-5y)[/tex] and the greatest common factor from [tex](2y-2)[/tex] . The two common factors for both of those are 5y and 2. Your equation should now look like this:
[tex]5y(y-1)[/tex] + [tex]2(y-1)[/tex]
The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:
[tex](5y+2)(y-1)=0[/tex]
Now equal both of the equations to 0 and solve for y to get both of the values of y.

This is a required question
Answer:
The answer is explained below
Step-by-step explanation:
The question is not complete, I would explain how to calculate the value of Z
The z score is a measure in statistic used to determine the number of standard deviations by which the raw score if from the mean of a normal distribution. If the z score is positive then the raw score is above the mean while if a z score is negative the raw score is below the mean. The z score (z) is given by the formula:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Where x is the raw score, μ is the mean and σ is the standard deviation.
Let us assume that the mean (μ) = 20 and the standard deviation (σ) = 3. To calculate the z score for x = 30 it is given by:
[tex]z=\frac{x-\mu}{\sigma}=\frac{30-20}{3}=3.33[/tex]
