Sarah uses a recipe to make 7 gallons of her favorite mixed-berry juice. The containers she plans to use to store the juice have a capacity of 1 pint. How many containers will Sarah need?
Answer:
72 containers
Step-by-step explanation:
As we know that
1 gallon = 8 pints,
So, 2 gallons = 16 pints.
Like wise 7 gallons needs 72 pints
So if there is a capacity of one pint so the number of containers that Sarah would need is 72 containers
hence, the same would be relevant

Answer:
2) 62°
Step-by-step explanation:
since there is a straight line (can also be called as a semi-circle), that gives us an idea that it is a 180 degree, because a whole circle is 360 degrees.
180-118 = 62°
Answer:
59° and 62°
Step-by-step explanation:
here's your solution
=> in the first picture , we know that sum of all angle on a straight line is 180°
=> so, angle ( ? + 121 ) = 180°
=> ? = 180° - 121°
=> ? = 59°
now , in second picture
=> ( x + 118° ) = 180°
=> x = 180° - 118°
=> x = 62°
hope it helps
find geometric probability
Answer: 67%
Step-by-step explanation:
Since we're not solving for area I would just divide this circle into 6 equal parts. 3 on both sides of the diameter. The orange parts take up about 120/180 on one sides of the circle. So 2/3 of half the circle are covered in orange which means 2/6 of the whole circle is covered in orange. Which leaves us with 4/6 blank or white area. 4/6 as a decimal is 0.6666667 or 67%
Answer:
66.67 % (Rounded to the nearest hundreth)
66.666..% or 66 2/3 %
Step-by-step explanation:
The area of the whole circle with radius 4 is 50.27
The white area is 4/6 = 2/3 of the total area = 33.51333333
The geometric probability is the favorable area divided by the total area
33. 513333 / 50.27 = 0.6666666 = 66.666666%

Find the image of the given point
under the given translation
Enter the number that belongs
in the green box.
Please helpp
Answer:
P' = (2, -6)
Step-by-step explanation:
In this translation, you just need to substitute x and y into the given translation to find what P' is. (x is -6 since it's the x-value of P, and y is -2 since it's the y-value of P):
where T(x, y) = (x + 8, y - 4) and x = -6 and y = -2,
T(-6, -2) = ((-6) + 8), (-2) - 4) (substitute x and y into the translation)
T(-6, -2) = (2, -6) (add and subtract)
So, P' = (2, -6)

What is the measure, in degrees, of ∠ABC ?
Answer:
50
Step-by-step explanation:
x+95 = 4x-10 ( alternate angles)
or, 4x -x = 95+10
or, 3x = 105
x= 35
x+95 = 35+95 = 130
130 + ABC = 180 ( linear pair)
or, ABC = 180-130= 50

The vertices of △JKL are J(−3, 4), K(3, 0), and L(−5, −4). The equation of the median to J is y=0. What are the coordinates of the centroid of △JKL?
Answer:j
Step-by-step explanation:
The coordinates of the centroid of △JKL are (-5/3 , 0)
What is centroid of a triangle and its coordinates?The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).
If the triangle has its vertices as [tex](x_1, y_1), (x_2, y_2) , \: (x_3, y_3)[/tex], then the coordinates of the centroid of that triangle is given by:
[tex](x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)[/tex]
The vertices of ΔJKL lies in first quadrant because the coordinated of the vertices are positive which means the vertices are in the form of (x,y).
If the ΔJKL reflects along the x-axis then the vertices are in the form of (x,-y). Now the ΔJKL reflects along the y-axis then the vertices are in the form of (-x,-y).
The given coordinates of the the vertices after transformation is J(−3, 4), K(3, 0), and L(−5, −4).
The equation of the median to J is y=0.
(-3 + 3 - 5 / 3 , 4 + 0 - 4/ 3) = (-5/3 , 0)

A tablecloth is 82 inches long. What is the length in feet and inches?
Answer: 6 feet and 10 inches
Step-by-step explanation:
Each foot has 12 inches in it
You can either divide 82 by 12 or
1 foot: 12 inches
2 foot: 24 inches
3 foot: 36 inches
4 foot: 48 inches
5 foot: 60 inches
6 foot: 72 inches
7 foot: 84 inches
Since 7 foot is too much you can now take 6 feet (72 inches) and subtract it from 82
82-72=10
10 meaning 10 inches
6 feet and 10 inches
You may also divide but you will get a decimal like this:
6.83333333
Unit conversion is a way of converting some common units into another without changing their real value. The length of the table cloth is 6 ft 10 inches.
What is Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
In terms of measurement, one foot is 12 inches.
1 ft = 12 inches
Given that the table cloth is 82 inches long. Therefore, the length in feet and inches are,
Length = 82 inches
= 82 / 12 foot
= 6 10/12 foot
= 6 ft 10 inches
Hence, the length of the table cloth is 6 ft 10 inches.
