Elena is binding a small booklet with a spine that is 21/4 inches long. She uses staples that are 7/16-inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?
Answers
Answer:
12 staples
Step-by-step explanation:
So the first thing we have to do is find the G.C.D (Greatest Common Denominator) between 21/4 and 7/16 which of course is 16 so your new fractions would be 84/16 and 7/16.
Now we have to divide both numbers I just used a fraction calculator for this but basically you multiply 84/16 by the reciprocal of 7/16 which is 16/7 and simplify which equals 12.
So it would take 12 staples to bind the booklet

Given u = ⟨root3, -1⟩ and v = ⟨3, –4⟩, what is u · v?
Answers
Answer:
3[tex]\sqrt{3}[/tex] + 4
Step-by-step explanation:
If u = < x₁, y₁ > and v = <x₂ , y₂ > , then
u • v = x₁x₂ + y₁y₂
Given
u = < [tex]\sqrt{3}[/tex], - 1 > and v = < 3, - 4 >, then

Solve for x in the equation x2 + 4x-4-8.
O x= -6 or x = 2
O x=-2+2V2
O x = -2 or x = 6
O x=2+25
Answers
Answer:
O x = - 6 or x = 2
Step-by-step explanation:
x² + 4x - 4 - 8 = 0
x² + 4x - 12 = 0
x² + 6x - 2x - 12 = 0
x(x + 6)x - 2(x + 6) = 0
(x + 6) (x - 2) = 0
x + 6 = 0 or x - 2 = 0
x = - 6 or x = 2
Thus, x = - 6 or x = 2

Laurie had three $2 off coupons for the mini-golf course, but everybody else had to pay $9 per person, the full price. What was the total cost for their group of 8 to play mini-golf?
A: $51
B:$62
C:$63
D:$66
Answers
Answer:
D
Step-by-step explanation:
9x8=71
2x3=6
71-6=66
Answer:
D $66
Step-by-step explanation:
So first we need to figure how much money she was able to deduct from the three $2 coupons. Remember the original price is $9
3×2=6 (which means she can get $6 off of the original price $9.)
9-6= 3 (So now she only has to pay $3 while the other seven people in her group pays the original price $9.)
9×7= 63 (So $9 for the 7 other people equals $63. That is how much they are paying. Now let's add Laurie's amount!)
63+3=66 (So altogether everyone including Laurie is paying $66.)
So the final answer is $66
(I hope this helps you! Have a wonderful day everyone!)

The measure of the angle ∠STR of the right-angle triangle ΔTSR will be 28.07°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The hypotenuse is named 68 m. The more limited leg is named 32 m. The more drawn-out leg is named 60 m. The right point is at point S. Point R is opposite the 60 m side. Point T is opposite the 32 m side.
The measure of the angle ∠STR of the right-angle triangle ΔTSR is calculated as,
Let 'x' be the angle ∠STR. Then the equation is given as,
sin x = 32 / 68
Simplify the equation, then we have
sin x = 32 / 68
sin x = 0.470588
x = sin⁻¹(0.470588)
x = 28.07°
The measure of the angle ∠STR of the right-angle triangle ΔTSR will be 28.07°.

What is an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=66x+y=6?
Answers
Answer:
An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:
[tex]y=-6x+7[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Given the equation
[tex]6x+y=6[/tex]
Writing in the slope-intercept form of the line equation
[tex]y = -6x + 6[/tex]
comparing with the slope-intercept form of the line equation
y = mx+b
Thus, the slope of line = m = -6
We know that the parallel lines have the same slopes.
Thus, the slope of the parallel line is also -6.
As the line passes through the point (2,−5).
Thus, using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope and (x₁, x₂) is the point
substituting the values m = -6 and the point (2,−5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-5) = -6 (x - 2)[/tex]
[tex]y+5=-6\left(x-2\right)[/tex]
subtract 5 from both sides
[tex]y+5-5=-6\left(x-2\right)-5[/tex]
[tex]y=-6x+7[/tex]
Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:
