Jada was using square stickers with a side length of 3/434 inch to decorate the spine of a photo album. The spine is 10 1/21012 inches long. If she laid the stickers side by side without gaps or overlaps, how many stickers did she use to cover the length of the spine?
Answer: The number of stickers she used to cover the length of the spine = 14.
Step-by-step explanation:
Given: The length of spine = [tex]10\dfrac12[/tex] inches = [tex]\dfrac{21}{2}[/tex] inches
Length of each sticker = [tex]\dfrac34[/tex] inch
If she laid the stickers side by side without gaps or overlaps, the number of stickers she use to cover the length of the spine = [tex]\text{(Length of spine)}\div (\text{Length of each sticker})[/tex]
[tex]=\dfrac{21}{2}\div\dfrac{3}{4}\\\\=\dfrac{21}{2}\times\dfrac{4}{3}\\\\=\dfrac{7\times2}{1}=14[/tex]
The number of stickers she used to cover the length of the spine = 14.
Solve for x.

if the original quantity is 8 and the new quantity is 2 what is the percent decrease
Answer:
75%
Step-by-step explanation:
12.5 percent decrease per 1, multiply by 6, =75
Answer:
It’s a 75% decrease
Step-by-step explanation:
2 is 25% of 8 so since 8-2= 6 and 6/2=3 so you’d do 25 x 3 = 75 giving you 75%

Paguei 74,00 por uma bolsa e uma sandália. A bolsa foi 23,00 mais barato q a sandália. Qual o preço da sandália?
Responda:
48,5
Explicação passo a passo:
Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5

solve the equation by factoring: 6x-0.2x^2=0
Please ill give brainliest to the correct answer
Answer:
The solution to the quadratic equation:
[tex]x=0,\:x=30[/tex]
Step-by-step explanation:
Given the equation
[tex]6x-0.2x^2=0[/tex]
6x - 0.2x · x = 0
Factor out common term -x
-x (0.2x - 6) = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]x=0\quad \mathrm{or}\quad \:0.2x-6=0[/tex]
solving
[tex]0.2x-6=0[/tex]
Multiply both sides by 10
[tex]0.2x\cdot \:10-6\cdot \:10=0\cdot \:10[/tex]
Refine
[tex]2x-60=0[/tex]
Add 60 to both sides
[tex]2x-60+60=0+60[/tex]
Simplify
[tex]2x=60[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{60}{2}[/tex]
Simplify
[tex]x=30[/tex]
Thus, the solution to the quadratic equation:
[tex]x=0,\:x=30[/tex]

Find the term to term rules for the following sequences:
b)
2, 6, 18, 54, 162
Answer: Please see explanation column for answer
Step-by-step explanation:
According to sequence 2, 6, 18, 54, 162
--we can see that it is a geometric sequence since to go from one term to the next requires us to multiply by 3 which is called the common ratio which is gotten by dividing the next by the previous.
ie term 2/ term 1= 6/2 = 3
term 3/ term 2= 18/6= 3
term 4/ term 3= 54/28= 3
term 5 / term 4= 162/54=3
term 6 will therefore be 162 x3 = 486
and term 7 = 486 x 3=1,458 and so on
Recall that nth term of GP is
Tn = ar^n-1
Where a= first term
r= common ratio
n= term
such that to easily find particular term, we plug in the values and calculate
for example the 10th term of the above sequence
Tn = ar^n-1
= 2 X 3 ^(10-1)
2 X 3^9
T10 =39,366
Malik and Tasha each worked three days in one week at the grocery store. Each day, Malik worked 2 fewer hours than Tasha. They worked a total of 18 hours that week. Find the number of hours that Tasha worked each day.
Answer:
Step-by-step explanation:
Firstly, since they worked 18 hours over 3 days, they worked a total of 6 hours each day. Since Malik worked 2 fewer hours than Tasha, we have that Tasha worked (6+2)/2 = 4 hours each day and Malik worked 2 hours each day.
What are the scale factor and the center of dilation?
Answer:
Scale factor 2.5, Center of dilation is (-8,3)
Step-by-step explanation:
A dilation is a non rigid transformation. We know that a center of a transformation expect translations mean that it dont matter what change we do to the the pre image to get the new image. The center will stay where it was at all times. Looking at the figure, between the pre image and new image the only point that stays is Point K and point K' . so K is the center of the dilation and that at (-8,3).. Since the pre image is smaller than the new image we know the image scale factor is greater than 1 so the scale factor is expanding. To find the scale let look point K and L we need to find how far are they away from each other and which in this case is 4. Now let look at point K' and Point L'. There distances is 10. You can do the same for K and J. K and J distance is 2 units right and 4 units down. K' and J' distance is 5 units right and 10 units down.
Using this let set a proportion of one point from bigger figure to smaller figure. Distance in current image/ Distance in pre image. Let use K and J so it will be 10/4=2.5 so the scale factor is 2.5

Use the figure above to solve for x
Answer:
x is equal to 7
Step-by-step explanation:
Because the two horizontal lines are parallel, we know that the angles at which they intersect the diagonal line will be identical.
We also know that on either side of the diagonal line, the sum of the angles between that and either of the horizontal lines will be 180.
In short, we know that the two values given have a sum of 180. With that we can quickly solve for x:
(x + 67) + (x + 127) = 180
2x + 194 = 180
2x = -14
x = 7
