an 8in by 12in picture has a frame of uniform width around it the area of the frame is equal to the area of the picture. what is the width of the frame
Answer:
2 inches
Step-by-step explanation:
The area of the frame will be the difference between the area of the picture with frame, and the area of the picture without. We want that difference to be equal to the area of the picture without the frame.
Let x represent the width of the frame. The overall length and width of the picture will be increased by 2x when the frame is added. Then we have ...
a = LW = (8+2x)(12+2x) . . . . area of picture and frame
b = LW = (8)(12) . . . . . . . . . . area of picture
a -b = b . . . . . . desired relationship between areas
Substituting and expanding the expressions for 'a' and 'b', we find ...
a -2b = 0 . . . . subtract b
(8 +2x)(12 +2x) -2(8)(12) = 0
4x² +40x -96 = 0 . . . simplify
x² +10x -24 = 0 . . . . . divide by 4
(x -2)(x +12) = 0 . . . . factor
The positive value of x that makes this true is x = 2.
The width of the frame is 2 inches.
I need help asap. This due tn!
Answer:
Anything before 0 is negative. In this case we’re trying to “plot” - 1 2/3. It has to be between -2 and 0 on this plot.
Now lets imagine we have a center line between -2 and 0.
You’d get
-2, -1, 0
Now using that benchmark/ estimate, go towards the LEFT between -1 and -2. Now when reached about half way, go forward for a bit more and you should receive it.
Thats it!
a/5+3=8
Please helI will mark BRAINLIEST
Answer:
A=25
Step-by-step explanation:
8-3=5
25/5=5
a=25
Answer:
A = 25
Step-by-step explanation:
To solve this equation, we have to find a number that can replace a that makes the equation true.
So, what number would fit?
Well, since a 5 is being divided by a, we have to find a number that 5 can divided by 5 that gets 5.
This way, you can add 5 to 3 and get 8
Well, 5 x 5 = 25
So, 25 / 5 = 5
So, if we set a to 25, the equation is true
25 / 5 =5
5 + 3 = 8
Correct Answer: 25

Jewel spins the pointer of a spinner. The spinner has 7 equal-sized sections labeled 1 to 7. What is the probability that Jewel will spin a 7?
Answer:
14
Step-by-step explanation:
It's a probability, divide favorable outcomes to total outcomes
Answer:
14%
Step-by-step explanation:
There are 7 sections of equal size.
The total number of possible outcomes is 7.
There is one single outcome that is desired, landing on 7.
probability of an event = (number of desired outcomes)/(total number of possible outcomes)
p(7) = 1/7 = 0.142857... = 14%
Answer: 14%
Question 15

Miranda wants to use a 15% off coupon on her $120 purchase at Macys.com. She is trying to
figure out how much she will save.
Which equation is the correct way to determine the accurate amount?
120 - 15% = x
120 - 15% = x
120 + 15% = x
120 + 15% = x
Question 16
2 pts
Answer:
120 - 15% × 120 = x
Step-by-step explanation:
All given answers are incorrect.
15% means 0.15
She is not subtracting 15% or 0.15 from 120.
She is subtracting 15% of 120 from 120.
The correct answer is
120 - 15% × 120 = x
The greatest distance across the continental United States is about less than 5000km. To fit a map in an 8.5in by 11 in what scale should I use
Answer:
1 in = 500 km
Step-by-step explanation:
It is nice to choose a scale that leaves a little border, so one could probably make it ...
10 in = 5000 km
1 in = 500 km
__
If you'd rather have a "nice" ratio, you could use ...
2.5 cm = 500 km ⇒ 1 : 20,000,000
_____
Additional comment
An inch is 2.54 cm, so using 2.5 cm for the same distance means the map is slightly smaller. It would end up about 9.8 inches wide, leaving a border of almost 0.6 inches on either side.
You might want a scale that makes it easy to draw using the tools you have. If your distances are in km, and you have an inch ruler, then the first choice might be better. If you have a centimeter ruler, then the second scale might work better for you.
The unitless scale is found by doing the division:
[tex]\dfrac{2.5\times10^{-2}\text{ m}}{5.00\times10^5\text{ m}}=\dfrac{1}{2\times10^7}=\dfrac{1}{20,000,000}[/tex]

A diamond ring costs $1,020 to manufacture and is sold in stores for $1,275. While, a ruby ring that normally sells for $290 is on sale for $203.
Answer:
The 2nd paragraph has the straightforward answer, technically.
This is an example of gross domestic product and today's marketing. When a product is usually paid more money to manufacture than it costs to actually sell. However, the usual difference between manufacturing cost and sales cost is on average is at most 5 - 15% of the manufacturing cost.
The second problem however is just the perfect example of sales and sales tax. The diamond ring is on sale for 30% off in this case, because 290 divided by its percent is equal to 30%, the remaining amount.

What is 15% of 130.00
Been staring at my screen for awhile at this. Please help!
1. Create a grid that is 5 squares wide by 2 squares tall. Shade 8 squares as shown above.
A. Look at the shaded:total in the gizmo table. What decimal and percent are modeled by the shaded squares?
Decimal: 0.8Percent: 80%Decimal part =
10 squares
8 shaded
0.2=2 squares shaded
so
8 squares shaded = 0.8
Percent part =
if 100% = 1 whole
1 whole = 10 blocks in gizmo table
then
8 blocks in gizmo table = 80%
since
1 block = 10%
10%x8=80
80%
B. Look at the unshaded:total row. What decimal and percent by the unshaded squares?
Decimal: 0.2Percent: 20%Decimal part:
If there are 2 unshaded squares
and we know that 1 square = 0.1
then, 2 squares = 0.2
0.2
Percent part:
if we know that 10 blocks = 1 whole
and 1 block = 10%
then 2x10%=20%
20%
1. The Gizmo gives two equivalent (equal) fractions — simplified and unsimplified — for the shaded:total and unshaded:total ratios. Record them below. (to see why these are equivalent, notice how many shaded and unshaded squares are in each row of the grid.)
[tex]\frac{shaded}{total}=\frac{8}{10}=\frac{4}{5}[/tex] [tex]\frac{unshaded}{total} =\frac{2}{10} =\frac{1}{5}[/tex]

Answer:
Decimal : 0.8

Answer:
ans = 9 degree
Step-by-step explanation:
81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)
81 + 4x + 5x + 18 = 180
99 + 9x = 180
9x = 180 - 99
9x = 81
x = [tex]\frac{81}{9}[/tex]
x = 9 degree

1. What number added to 2.1835 gives 3?
2.The sum of 3.9 and 6.93 subtracted from 38.35 gives what number?
3.What should be added to 4.1648 to get 8?
4.By how much is the difference between 604 and 406.064 less than their sum?
5.By how much should 18.35 be decreased to get 6.4987?
Answer:
1. 0.8165 ; 2. 27.52 ; 3 = 3.8352 ; 4. 812.128 ; 5. 11.8513
Step-by-step explanation:
1. 3 - 2.1835 = 0.8165
2. 38.35 - (3.9 + 6.93) = 27.52
3. 8 - 4.1648 = 3.8352
4. 604 + 406.064 = 1010.064
604 - 406.064 = 197.936
1010.064 - 197.936 = 812.128
5. 18.35 - 6.4987 = 11.8513
