y+4=2y-3, find y and show your work.
Answer:
y = 7
Step-by-step explanation:
we can substitute y for 7 in the equation to confirm that y = 7
7 + 4 = 2(7) - 3
7 + 4 = 14 - 3
11 = 14 - 3
11 = 11

Simplify the following surd expressions-
Answer:
[tex]\sqrt{2}[/tex] and 4[tex]\sqrt{11}[/tex]
Step-by-step explanation:
To simplify like surds, add/ subtract the coefficients.
(a)
[tex]\sqrt{2}[/tex] (6 - 5)
= [tex]\sqrt{2}[/tex] (1)
= [tex]\sqrt{2}[/tex]
(b)
[tex]\sqrt{11}[/tex] ( 1 + 3)
= [tex]\sqrt{11}[/tex] (4)
= 4[tex]\sqrt{11}[/tex]

Sammi designs a quilt composed of squares as shown what is the measure of angle z
Answer:
z = 52 degrees
Step-by-step explanation:
the angle adjacent to angle Z is 38 degrees because it is vertical and equal to the angle named as 38 degrees
i suppose these are squares, which have right angles (90°)
so, 90 - 38 = m ∠ Z

Answer:
4
Step-by-step explanation:
If you graphed it out you would see that the rise/run would be 4 over 1 which is also 4. On this table, you can see that the x is going up by 2 and the y is going up by 8 and 8/2 is also the same as 4/1 or 4 (rise/run = y/x).

What would be the total cost of software F
over time?
The total cost of software F over time is $5000.
What is a satisfaction rate?For questions involving Customer Satisfaction Score, "Satisfaction Rate" is computed. It's calculated to provide you with an overall satisfaction rating of your respondents' responses to your goods and services.
Cost of Software F = $10000
Satisfaction rate with Software F = 90%
Cost of satisfaction level = $0
Cost of dissatisfaction level = $5000
Percentage of not satisfied = 10%
The total cost of Software F over time is :
= {($10000 x 90% - $0) + ($10000 x 10% - $5000)}.
= $5000
Therefore, cost of software F over time is $5000.

A square of side 72 cm and a rectangle of length 90 cm have same perimeter. Find the difference in areas ?
A)216cm2
B)304cm2
C)324cm2
D)328cm2
Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
Answer:
C) 324cm²
Step-by-step explanation:
1) they have the same perimeter so to find it you add all four sides of the square because they are all the same ( 72+72+72+72=288)
2) now you multiply 90 by 2 because the rectanglehas to sides of the same length(90×2=180) the answer you get you are going to subtract to 288 (288-180=108)
3) now divide 108 by 2 (108÷2= 54) the answer you get equals the width of the side of the rectangle
4) to get the area of the rectangle you multiply 54 with 90 (54×90=4,860) to get the area of the square you multiply 72 times 72 (72×72=5,184)
5) now you subtract 5,184 and 4,860 ( 5,184-4,860= 324cm²)
