After 4 months of a new nutrition program rashid has lost 16% of his original weight he lost 36lb what was rashids original weight?
Rashids original weight based on the information illustrated is 225lb.
What was the original weight?From the information given, after the nutrition program rashid has lost 16% of his original weight he lost 36lb.
Let the original weight be given as x.
Therefore, 16% × x = 36
0.16x = 36
Divide through by 0.16
0.16x / 0.16 = 36 / 16
x = 36/0.16
x = 225lb
The weight is 225lb.

Given:
A bag of popcorn costs $[tex]3.33[/tex]Miguel bought [tex]20[/tex]packs of juice bottlesThe total cost before tax was $[tex]23.33[/tex]To find: Cost of each bottle of juice?
It is given that Miguel bought snacks for his team's practice which includes a bag of popcorn, and [tex]20[/tex] packs of juice bottles out of which the bag of popcorn cost him $[tex]3.33[/tex] , and the total cost before tax of all the items costs him $[tex]23.33[/tex]
Now we have to find that how much each bottle of juice costs him as asked in the given question.
Let the bag of popcorn's amount be x and the pack of bottle juice is y
Now according to the linear equation in two variable
[tex]x*1+y*20=23.33[/tex]........(1)
where 1 is the total pack of popcorn bag and [tex]20[/tex] the amount of bottle juice packs
As we know that [tex]x=3.33[/tex] since a bag of popcorn costs him $[tex]3.33[/tex]
Now put the value of x in (1) hence,
[tex]3.33*1+y*20=23.33[/tex]
On further solving we get,
[tex]20y=20[/tex]
On further solving we get,
[tex]y=1[/tex] as the price of every juice of bottle.
Hence a bottle of juice costs him $[tex]1[/tex]

ANGLES what is x,need quick please
Answer: x = 68
Step-by-step explanation:
Because the 22 degrees and x make up a complementary angle (add up to 90 degrees) we can subtract 22 from 90 to get x.
90-22 = 68
Which equation that gives the rule for this table.x: 3, 4, 5, 6y: 10, 11, 12, 13A: Y= -x + 7B: Y = x + 7C:Y = 6x + 7OrD: Y= -6 + 7
To solve this problem we can evaluate te terms in the table in each equation so:
For A) y = -x + 7
we replace (3,10)
[tex]\begin{gathered} 10=-3+7 \\ 10=4 \end{gathered}[/tex]So A is incorrect.
For B) y = x + 7

The standard deviation of the mass of the bluetits to 3 significant figures is 1.30.
What is the standard deviation?Standard deviation is used to determine the variation of a dataset. Standard deviation is the spread of a data from the mean of the dataset. The higher the value of the standard deviation, the greater the spread of the dataset.
In order to determine the standard deviation, take the following steps:

Answer:
Explanation:
The volume of a cylinder is given by
[tex]V=\pi r^2h[/tex]Now, to correct the order of the cylinders from least to greatest, we have to calculate the volume of each.
(a). A cylinder with a diameter of 28 units and a height of 18 units.
Diameter is 2 times radius; therefore, r = 14 and the volume is
[tex]V=\pi(14)^2\times18[/tex][tex]V=3529\pi[/tex](b). A cylinder with a radius of 13 units and a height of 17 units.
The volume is
[tex]V=\pi(13)^2\cdot17[/tex][tex]V=2873\pi[/tex](c). A cylinder with a diameter of 30 units and a height of 14 units.
The radius is 15 units; therefore, the volume is
[tex]V=\pi(15)^2\cdot14[/tex][tex]V=3150\pi[/tex](d). A cylinder with a radius of 12 units and a height of 20 units.
The volume is
[tex]V=\pi(12)^2\cdot20[/tex][tex]V=2880\pi[/tex]Hence, from least volume to greatest volume the order is

How long will it take? How many tests will each child have passed? In weeks, the children will each have passed tests.
Solution
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Represent the unknown terms
Let x represents the number of weeks
Let y represents the total number of test passed
STEP 2: Interpret the statements
For Rebecca
[tex]y=2x+12[/tex]For Marie
[tex]y=5x+3[/tex]STEP 2: Find the number of weeks they will pass the same amount of test.
This means that y will be equal to y
[tex]\begin{gathered} y=y \\ 2x+12=5x+3 \\ 2x-5x=3-12 \\ -3x=-9 \\ x=\frac{-9}{-3}=3\text{ weeks} \end{gathered}[/tex]Hence, they will both pass the same number of tests in 3 weeks

A wire of length 22cm is bent in the shape of a circle . find the area of the circle. if the same wire is recent in the form of a square, find it's area which figure encloses more area
The circle is found to have the more area as compered to the square.
What is termed as the perimeter?A perimeter is a loop that encompasses, encircles, or outlines a two-dimensional shape or length. The circumference of a circle or perhaps an ellipse is its perimeter.For the given question;
The length of the wire is given as 22 cm.
The wire is bent in the circle.
Then, the perimeter of the circle is 22 cm.
Perimeter = 2πr = 22 cm.
Where, π = 3.14 and r is the radius of the circle.
2πr = 22 cm.
r = 11/π 11/3.14
The area of the circle is found as;
Area = πr²
Put the values.
Area = 3.14(11/3.14)²
Area = 38.53 cm².
For the square.
Perimeter = 4 side
22 = 4 side
side = 22/4 = 11/2 = 5.5
Area of square = side²
Area of square = 5.5²
Area of square = 30.25 cm².
Thus, the circle is found to have the more area as compered to the square.
