Answer:
Vincent will be able to buy the sneakers, while David will not be able too.
Step-by-step explanation:
I believe this is true because for David,
6% of 86$ is 5.16$
so 86 + sales tax (which is 5.16) = 91.16$
David only has 90$ so he can't afford the sneakers. They are 1.16$ over his budget.
While for Vincent,
9% of 86$ is 7.74$
so 86 + sales tax (which in this case is 7.74) = 93.74
Vincent has 95$ to spend so he can afford the shoes.
I am not exactly sure if all calculations are correct, but I hope this helps! :)

Brendan says that the negative of - 1/3
is 3 because they are on opposite sides of zero when they are plotted on the number line.
Is Brendan correct? Explain your answer.
Answer:
No! Brendan has totally got the wrong idea.
Step-by-step explanation:
Numbers on the right hand side of zero are said to be positive, while, the numbers on the opposite side are said to be negative.
That means Brendan's correct in saying that -1/3 lies on the opposite side of 3, since negative numbers lie on the opposite side of the positives.
But,
Negative "of" a number is the same number with opposite sign.
That is, if a number is 3 units away from the zero, it's negative will also be 3 units away from zero, but on the opposite side.
-1/3 and 3 do not lie at the same distance from zero.
-1/3 would be approached before -1 by walking in the negative direction whereas 3 would be approached after 1.
Therefore, Brendan is wrong as the negative of a number has opposite sign but same "magnitude".

2 sin A = √3
=》sin A = √3/2
■ If sin A = √3/2, then A = 60° (trigonometric value)
So,
cot A = cot 60° = 1/√3
1 - cot²A / 2 cot A
= 1 - (1/√3)² / 2*(1/√3)
= 1 - (1/3) / 2/√3
= 2/3 / 2/√3
= 2/3 / 2√3/3
Cancel out the 3 in the denominator.
= 2/2√3
= 1/√3
1 - cot²A / 2 cot A = 1/√3

Answer:
√3/3Step-by-step explanation:
2 sinA = √3 ⇒ sinA = √3/2Rewrite as:
(1 - cot²A)/2cotA = (1 - cos²A/sin²A)/(2cosA/sinA) = sinA[(sin²A - cos²A)/sin²A] / (2cosA) =(2sin²A - 1)/(2sinAcosA) = (2sin²A - 1)/[2sinA√(1 - sin²A)]Substitute the value of sinA:
(2(√3/2)² - 1) / [√3 √{1 - (√3/2)²)] =(3/2 - 1)/[√3√(1/4)] =(1/2) /(√3/2) = 1/√3 = √3/3What does: 8w+22=34 equal?

The inequality that models the situation is:
[tex]15000 + 4s \geq 450000[/tex]
Solving it, it is found that they need to sell at least 108,750 shirts.
During the day:
They earned 15000 in mask sales.They will sell s shirts, and earn a total of of 4s.Hence, the earnings are:
[tex]T = 15000 + 4s[/tex]
They want to earn at least 450,000, hence:
[tex]T \geq 450000[/tex]
[tex]15000 + 4s \geq 450000[/tex]
Solving it:
[tex]15000 + 4s \geq 450000[/tex]
[tex]4s \geq 435000[/tex]
[tex]s \geq \frac{435000}{4}[/tex]

What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
Scale of the drawing : Length in meters is in the ration 3 cm : 4 m
Length of the soccer field is 108 m
Now , length of 108 m soccer field in scale of drawing = x
From proportion formula , we can deduce that
3 : 4 : : x : 108
So ,
3/4 = x/108
Multiply by 108 on both sides , we get
( 3 x 108 ) / 4 = x
x = 3 x 27 cm
x = 81 cm
Hence , length of the field in the drawing is 81 cm

Answer:
[tex]x=\frac{275}{62}[/tex] , [tex]y=\frac{127}{31}[/tex]
Step-by-step explanation:
I will use the elimination method.We want to make the X's the same:
[tex]24x-15y=45[/tex]
[tex]24x+16y=172[/tex]
Because the signs of the X's are the same we subtract the 2 equations to make:
(I put the second one on top of the 1st)
[tex]31y=127[/tex]
So:
[tex]y=\frac{127}{31}[/tex]
Substitute y into either equation 1 or 2:
(I chose equation 1)
[tex]8x-5(\frac{127}{31})=15[/tex]

Answer:
equation: (4x +8)° = (2x +3)° +51°exterior angle: 100°Step-by-step explanation:
The relevant relation is "the exterior angle is equal to the sum of the remote interior angles." That means ...
(4x +8)° = (2x +3)° +51° . . . equation to solve for x
2x = 46 . . . . . . . . . . . . . divide by °, subtract 8+2x
x = 23 . . . . . . . . . . . . divide by 2
Then the exterior angle is ...
(4x +8)° = (4(23) +8)° = 100°
_____
Additional comment
Instead of solving for x, we can solve for (2x+3). We can do that by subtracting 5+2x from both sides to get 2x+3 = 49. Then the exterior angle is the sum 49+51 = 100 degrees. (We don't actually care about the value of x.)

Multiple Choice= 2 points each
Short Response= 4 points each
Step-by-step explanation:
You can set up a system of equations to find out how many points each type of question is worth.
x= multiple choice
y= short response
Equation 1 (You)
23x+10y=86
Equation 2 (Your Friend)
28x+5y=76
Solve with elimination. Multiply the second equation by negative 2 to cancel out the y-variable.
-2(28x+5y=76)
-56x-10y=-152
Subtract both equations together.
23x+10y=86
-56x-10y=-152
-33x= -66
x=2
Now that we found x, plug it into the first equation to solve for y.
23x+10y=86
23(2)+10y=86
46+10y=86
10y=40
y=4
Each multiple choice is worth 2 points, and each short answer response is worth 4 points.

In the accompanying diagram, overline BA perp overline BD and overline BC perp overline BE Which statement is true?
The measure of angle 1 is equal to angle 3
From the diagram, if BA is perpendicular to BD, then;
m<1 + m<2 = 90 degreesSimilarly, if BC is perpendicular to BE, then;
m<2 + m<3 = 90 degreesEquating both expressions will give:
m<1 + m<2 = m<2 + m<3Subtract m<2 from both sides
m<1 + m<2 - m<2= m<2 + m<3 - m<2
m<1 = m<3

Regan cycles 78 miles in 6 hours.
His average speed for the first 30 miles is 15 mph.
Work out Regan's average speed for the last 48 miles.
Answer:
12 mph
Step-by-step explanation:
First 30 miles while cycling at 15 mph. This means he spent 2 hours here.
Thus the 4 hours on the last 48 miles.
Average speed = distance / time
Average speed = 48 miles / 4 hours
Average speed = 12 mph
Therefore Regan's average speed is 12 mph for the last 48 miles.
