Allison measures some artwork for framing. The first picture is 9 3/4 inches long and the second is 7 1/4 inches long. What is the difference in length of the art?
Answers
Answer:
2 2/4
Step-by-step explanation:
Since the first picture is 9 3/4 and the second is 7 1/4. You have to subtract to find the answer.
Ex:
5 - 1 2/4 = ?
First lets turn five in to a fraction 5 -> 5/1
Now lets turn one and a half into an improper fraction 1 2/4 -> 6/4
We can now subtract easily!

Answer:
y = 1/13 + 59/13
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - 5 / -7 - 6
-1 / -13
1/13
y = 1/13x + b
4 = 1/13(-7) + b
4 = -7/13 + b
59/13 = b
y = 1/13 + 59/13
(a + b)(a - b) = a^2 - b^2
1. Multiply the numerator and the denominator by the complex conjugate of the denominator.
2. Simplify the results into the real part and the imaginary part.
Divide the complex numbers. Show all work.
Answers
Answer:
Step-by-step explanation:
hello : given z = (-6-10i)/(4+7i)
the complex conjugate of the denominator is : 4-7i
1. Multiply the numerator and the denominator by the complex conjugate of the denominator: z = (-6-10i)(4-7i)/(4+7i)(4-7i)
use identity : (a + b)(a - b) = a² - b² calculate the product : (4+7i)(4-7i)
(4+7i)(4-7i) = 4² -(7i)² =16 -49i² =16+49 = 65..... ( i² = -1)
2) Simplify the results calculate the numerator : (-6-10i)(4-7i)
(-6-10i)(4-7i) = -24+42i -40i+70i² = -24+42i -40i-70 .....( i² = -1)
(-6-10i)(4-7i) = -94+2i
now : z = (-94+2i )/65 = (-94/65) +(2/65) i
the real part is : ( -94/65) and the imaginary part is : 2/65

Answers
Answer:equal
Step-by-step explanation:
Answer:
x is less than or equal to 3
Step-by-step explanation:
subtract three from both sides which will give you 2x is greater than or equal to -6. then divide by -2 on both sides to isolate x (dividing by a negative number flips the sign and a negative divided by a negative equals a positive) so then you get x is less than or equal to 3

In the following diagram, medians AD and BE intersect at F. Which of the following segments would not be true
1) ECD~ACB
2) EF= 1/2EB
3) ED||AB
4) the median drawn from C would pass through F
Answers
The segment that is false is (2) EF= 1/2EB
The median lines of a triangle always meet at a point.
This means that the line from point C is true (option 4 is true)
The median divides the side lengths of the triangle into equal segments.
However, the centroid at point F do not divide line EB into equal segments
This means that:
The equation EF= 1/2EB is false
Hence, the segment that is false is (2) EF= 1/2EB

Lu is making a quilt that is 20 squares wide and has 15 rows. The border of the quilt is made by using each toy design equally as often. There are a total of 6 toy designs. Each square can hold one design. How many of each design does she use for the border?
Answers
Answer:
Out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.
Step-by-step explanation:
HEre the width = 20 and length = 15
The perimeter = 2(l+b)
= 2( 20+ 15) = 70
The border of the quilt has 70 squares. Each square can have 1 design and there are 6 designs
Number of repetitions for each design = 70/6= 11. 67
6 designs can have 11 repetitions for 66 boxes= 6 *11= 66
4 squares will be left out. 70-66= 4
4 design can have additional repetition.
Meaning out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.

If you have a new deck of shuffled cards, what is the probability you will choose an ace? (52 cards, no jokers) A) 1 13 B) 1 2 C) 1 4 D) 1 6
Answers
Answer:
B 1/2
Step-by-step explanation:
I looked it up.
But I think it'd be C because there would be 4 aces in the deck, and C has 1/4
Answer: 1/13 is the correct answer.
Step-by-step explanation: You put the total amount of aces, which is four, on the top part of your fraction and the total number of 52 cards on the bottom of your fraction. Since four will divide into both numbers, you simplify 4/52 to get 1/13. 4 divided by four is one. 52 divided by 4 is 13. That is how you get your 1/13 from 4/52. Answer was confirmed correct on the test I took. I hope this helps you! Thanks!
