How many 1/4’s are in 2/3?
Answer:
We'll leave 2/3 as it is and reciprocate 1/4 into 4/1. 2/3 × 4/1 = 8/3 which becomes 2.66. So 1/4 will go into 2/3 2.66 times.
Step-by-step explanation:
Answer:
1/4 is in 2/3 2 2/3 times

Yes
Step-by-step explanation:
0.8 is less than 1 and 6 is greater than one so 6 is greater than 0.8. :)
The radius of a circle can be approximated using the expression √(A/3). A circular kiddie swimming pool has an area about 28 square feet. An inflatable full-sized circular pool has an area of about 113 square feet. How much greater is the radius of the full-sized pool than the radius of the kiddie pool? round to the nearest whole number.
It says Hint: First find the radius of each pool by substituting for A in the expression. Divide by 3 before approximating square root.
Answer:
yeah I know you are literally perfect for you to be home
By using the expression to approximate the radius of a circle, we want to compare the radius of the two pools. We will find that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.
The expression for the radius of a circle is:
R = √(A/3)
Where A is the area of said circle.
The circular kiddie swimming pool has an area of 28ft^2, we just replace that in the above expression to get:
R = √(28 ft^2/3) = 3 ft
The full-sized pool has an area of 113 ft^2, then its radius is:
R' = √(113 ft^2/3) = 6 ft
To see how much greater is the radius of the full-sized pool than the radius of the kiddie pool, we just take the quotient:
R'/R = 6ft/3ft = 2
Meaning that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

What is the slope of a line parallel to line A?
A. -4/7
B. -7/4
C. 4/7
D. 7/4
Answer:
The answer is C.4/7
Step-by-step explanation:
First of all, parallel lines have the same gradient (slope), so if you find the slope for line A this will be the same slope as the line parallel to it (line A).
Step 1: find any two points from line A.point 1: (0,4) Where, [tex]x_{1} =0[/tex] and [tex]y_{1}=4[/tex]
point2: (-7,0) Where, [tex]x_{2} =-7[/tex] and [tex]y_{2} =0[/tex]
Step2: write the formula of the slope:[tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
Step3: substitute the numbers in the formula:[tex]m=\frac{0-4}{-7-0}[/tex]
Step4: simplify the formula to get the answer to the slope:[tex]m=\frac{-4}{-7}[/tex]
[tex]=\frac{4}{7}[/tex]
So the answer is:C. 4/7
(note: this is the slope of line A and any line parallel to line A)

Step-by-step explanation:
Only hash channel catfish typically was about 0.06 g during the first six weeks of life at weight increase about 10% each day right a exponential model for the weight how much will the catfish gain weight after six weeks
Answer:
3.225 gram
Step-by-step explanation:
Given that :
Initial weight = 0.06g
Rate of increase, r = 10% = 0.1 per day
Weight gain after 6 weeks
For an exponential model. f(x)
f(x) = a(1 + r)^x
Where ; a = initial amount ; r = growth rate ; x = period
Our model becomes :
f(x) : 0.06(1 + 0.1)^x
f(x) = 0.06(1.1)^x
Number of days in 6 weeks = 6*7 = 42 = x
f(42) : 0.06(1.1)^42
= 3.285 gram
Hence, weight gain after 6 weeks :
(3.285 - 0.06) g = 3.225 gram

Answer:
Total surface area
1) 46cm²
4) 304cm²
Step-by-step explanation:
1) First you need to work out each face on its own, opposites will be the same such as the front and back, top and bottom, side to side, because its a rectangle.
Formula : Base x height
Front/back : 5x3=15 and 15 =30 (added together)
top/bottom : 1x5= 5 and 5 = 10
side/side : 3x1= 3 and 3 = 6
30+10+6=46cm²
4) lets work out the easy ones first using the same formula from question 1 for one surface area but this is a trapezium, which is a irregular quadratical shape so the sides would most liky be different from each other except the front and back.
Top : 5x8=40
bottom : 3x10=30
right side : 12x8=96
Left side : 12x10=120
front/back= 12x3=36 / 2 = 18
Because if u added another side to make it a rectangle then divide by 2 would get the answer or 1/2 x base x height also works.
40+30+96+120+18=304cm²

If the circumference of a circle is 82p , then the value of ‘r’ is
(i) 41 cm
(ii) 82 cm
(iii) 21 cm
(iv) 20 cm
Answer:
41cm
Step-by-step explanation:
The circumference of a circle is 82π
Therefore r can be calculated as follows
2 × π × r= 82× π
2πr= 82π
r = 82π/2π
r= 41
Hence r is 41cm

Step-by-step explanation:
Karina owns a bakery where she orders both green apples and red apples to use in her baked goods. The supplier of the green apples says that 8% of their green apples are bruised. The supplier of the red apples says that 6% of their red apples are bruised.
Each week, Karina orders 120 of each type of apple, and she looks at the difference (Green−Red) between the proportions of apples with bruises in each order.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
A. Approximately normal, because we expect 10 bruised and 110not-bruised in both orders, and all of these counts are at least 10.
B. Approximately normal, because we expect 16 bruised and 104 not-bruised green apples, and 12 and 108 for the red apples, and all of these counts are at least 10
C. Not normal, because we expect fewer than 10 bruised apples in both orders.
D. Not normal, because we expect fewer than 10 not-bruised apples in both orders.
Not normal, because we expect fewer than 10 bruised apples in both orders.
