Answer:
[tex]\dfrac{7}{12}[/tex]
Step-by-step explanation:
Method 1
convert the fractions so that their denominators are 12:
[tex]\dfrac12=\dfrac{1 \times 6}{2 \times 6}=\dfrac{6}{12}[/tex]
[tex]\dfrac23=\dfrac{2\times4}{3\times4}=\dfrac{8}{12}[/tex]
From inspection, we can determine that the fraction that lies exactly halfway between [tex]\dfrac{6}{12}[/tex] and [tex]\dfrac{8}{12}[/tex] is [tex]\dfrac{7}{12}[/tex]
Method 2
Find the difference between the fractions and divide by 2:
[tex]\dfrac{\dfrac23-\dfrac12}{2}=\dfrac{1}{12}[/tex]
Add this to the smallest fraction (1/2):
[tex]\dfrac12+\dfrac{1}{12}=\dfrac{7}{12}[/tex]

3 tomatoes cost $1.29
How much will 5 tomatoes
cost?
Answer:
$2.15
Step-by-step explanation:
Since 3 Tomatoes cost $1.29
Then let's first find how much is 1 Tomatoes.
To do that we have to divide Cost by # of Tomatoes
3/1.29 = 0.43
Thus, 1 Tomatoes Cost 0.43
Now, the question is: How much will 5 tomatoes cost?
Therefore, 0.43 * 5 =2.15
Hence, 5 Tomatoes cost $2.15

What is the slope of the line that is perpendicular to the line that goes through the two points (-8, 3) and (4, 27)?
m= lype youiſ answer
Answer:
-1/2 or -0.5
negative half
Step-by-step explanation:
slope of regular line= (y1-y2) / (x1-x2)
(27-3) / (4 - -8)
24 / (4+8)
24 / 12 = 2
the slope of a perpendicular line is the negative reciprocal
the negative reciprocal of positive 2/1 (2 as a fraction) is:

Gabriella needs 120 meters of fence to surround a rectangular garden.
The length of the garden is three times its width, w.
How wide is the fence?
To fence a rectangular garden, we need to fence the length 2 times, and the width 2 times.
So, it will take 120 : 2 = 60 meters of fence to fence 1 length and 1 width
-> The length = 60 : (3+1)x3 = 45 (meters)
-> The width = 60 - 45 = 15 (meters)
Recheck : (45+15) x 2 = 120 and 45:15 = 3
(If it's wrong you can tell me, I don't really know what do you mean by how wide is the fence)
The width of the rectangular garden, for which Gabriella needs 120 meters of fence to surround it is 15 units long.
What is the perimeter of a rectangle?The measure of the boundary of the sides of a rectangle is called its perimeter. The perimeter of a rectangle is twice the sum of its length and width.
[tex]P=2(l+w)[/tex]
Here, (l) is the length of the rectangle and (w) is the width of the rectangle.
Let suppose the length of the garden is l units long. The length of the garden is three times its width, w. Thus,
[tex]l=3w[/tex]
Gabriella needs 120 meters of fence to surround a rectangular garden. This fencing is equal to the perimeter of the rectangular garden. Thus,
[tex]P=2(l+ w)\\120=2(l+ w)[/tex]
Put the value of length from equation 1 to this equation,
[tex]120=2(3w+ w)\\3w+w=\dfrac{120}{2}\\4w=60\\w=\dfrac{60}{4}\\w=15\rm\; units[/tex]
Thus, the width of the rectangular garden, for which Gabriella needs 120 meters of fence to surround it is 15 units long.

Darius buys a shirt for $15. 25. The next month , the store increases the price of the shirt to $18. 75. What is the percent increase in the price of the shirt
Answer:
23%
Step-by-step explanation:
Step 1. Find increase of price amount
18.75 - 15.25 = 3.50
Step 2. Find the percentage increase
- Since we are finding the percent increase, we know that we need to find 3.50 is ____% of 15.25. We can simply do 3.50/15.25, which can be simplified to approximately 0.23.
- Note that percentage = 100 times decimal
100 x 0.23 = 23
The answer is 23%

x=−19
x=−16
x=−14 1/2
Answer:
(a) -20 1/2

HELP!! 2. in the figure, x is an exterior angle to the triangle below.
a) explain why x is equal to the sum of the measures of the two nonadjacent interior angles. You need to present the equation with the steps/work that proves this theorem.
Step 1: __ Step 2: __ Step 3: __
(b) what is the measurement of < x ?
Answer:
< x = 120°
Step-by-step explanation:
Step 1:
According to angle sum property,
y + 50 + 70 = 180
Step 2:
x and y are linear pairs, forming a supplementary angle.
Therefore,
x + y = 180
Step 3:
Since they are both equal to 180, equate the values
y + 50 + 70 = x + y
x = 70 + 50
x = 120
