Nurses at a hospital weigh five newborn babies and round the weights to the nearest whole number. Which of the weights round to 8 pounds?
solve the expression 2xdivided by 6 (x=12)
Answer:
4
Step-by-step explanation:
first you plug in 12 for x so it would then be 2(12) divided by 6 and then follow the rules of math so you would multiply 12 and 2 which is 24 then 24 divided by 6 is 4
Kay is interested in getting chickens so she can have fresh eggs before she buys her chickens she wants to find the mean number of eggs each one will lay she begins by
randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month she finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs the resulting interval is (22.96, 26.64) which of the following correctly interprets the 90% confidence interval for the true mean number of eggs chickens from this poultry farm may within one month?

The volume of a hemisphere with a radius of 5.7 m is 193.83534 m³.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies. Volume is measured in cubic units like m3, cm3, in3, etc.
Volume is sometimes referred to as capacity.
We have,
Radius = 5.7 m
So, the Volume of Hemisphere
= 2/3 πr³
= 2/3 x 3.14 x (5.7)³
= 2/3 x 3.14 x 185.193
= 193.83534 m³
Thus, the volume is 193.83534 m³.

8 3/5 = -4x + 5 3/5 ??
Solution??
Answer:
x=−3/4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
435=−4x+285
Step 2: Flip the equation.
−4x+285=435
Step 3: Subtract 28/5 from both sides.
−4x+285−285=435−285
−4x=3
Step 4: Divide both sides by -4.
−4x−4=3−4
x=−34
Answer:
as a decimal: [tex]x=-0.75[/tex]
as a fraction: [tex]x=-\frac{3}{4}[/tex]
Step-by-step explanation:
note: i'm going to convert the fractions to decimals because i prefer working with decimals rather than fractions :)
[tex]8\frac{3}{5}[/tex] as a decimal is [tex]8.6[/tex][tex]5\frac{3}{5}[/tex] as a decimal is [tex]5.6[/tex]the equation is now [tex]8.6=-4x+5.6[/tex]first, subtract 5.6 from both sides of the equation.
[tex]5.6[/tex] and [tex]-5.6[/tex] cancel each other out, leaving you with [tex]-4x+0[/tex] on the right side of the equation. it's not necessary to leave the [tex]0[/tex] in the equation, so just leave it as [tex]8.6=-4x[/tex]now subtract [tex]5.6[/tex] from the left side of the equation. [tex]8.6-5.6=3[/tex], therefore the equation is now [tex]3=-4x[/tex]then divide both sides of the equation by -4.
you are left with [tex]x[/tex] on the right side of the equation and [tex]-\frac{3}{4}[/tex] or [tex]-0.75[/tex] on the left side of the equation, aka [tex]x=-0.75[/tex] or [tex]x=-\frac{3}{4}[/tex]and that's it! the solution as a fraction is [tex]x=-\frac{3}{4}[/tex] and as a decimal is [tex]x=-0.75[/tex].
if you want to check the solution, just plug one of those values in for [tex]x[/tex] in the original equation. since i converted it all to decimals, i'll check my answer using [tex]-0.75[/tex] for [tex]x[/tex] in [tex]8.6=-4x+5.6[/tex].
first, plug in -0.75 for x.
[tex]8.6=-4x+5.6[/tex] ⇒ [tex]8.6=-4(-0.75)+5.6[/tex]begin simplifying by multiplying -4 and -0.75.
[tex]-4(-0.75) = 3[/tex][tex]8.6=3+5.6[/tex]add 3 and 5.6.
[tex]3+5.6=8.6[/tex][tex]8.6=8.6[/tex]since both sides of the equation are equal, that means your [tex]x[/tex] value is correct and therefore a solution to the equation!! :)

AC =
in.
Answer:
AC = 16 in.
Step-by-step explanation:
AD = CD = 10 in.
BD = 6 in.
AC = 2(AB) = ?
Apply pythagorean theorem to find AB
AB² = AD² - BD²
Substitute
AB² = 10² - 6²
AB² = 64
AB = √64
AB = 8
Therefore:
AC = 2(AB) = 2(8)
AC = 16 in.

The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)+2.
Which statement about the graphs is true?
The vertex of the graph of g is 2 units above the vertex of the graph of f.
The vertex of the graph of g is 3 units to the right of the vertex of the graph of f.
The vertex of the graph of g is 2 units below the vertex of the graph of f.
The vertex of the graph of g is 2 units to the left of the vertex of the graph of f.
Answer:
The vertex of the graph of g is 2 units above the vertex of the graph of f.
Step-by-step explanation:
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.
Then the g(x) will be
g(x) = x² + 2
We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.
The graph is shown.
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).
Thus, the correct option is A.

Find the equation of the parabola whose vertex is the origin and whose directrix is x = -4
Try this option:
1) if V(0;0) and x= -4, then common view of the required equiation is:
(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;
2) if the V(0;0), then h=k=0 and the required equiation is:
y²=4px;
3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:
y²= -16x
answer: y²= -16x
A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 25 feet more than the length of the shortest side. Find the dimensions if the perimeter is 157 feet
What is the length of the shortest side?
What is the length of the second side?
What is the length of the third side?
Answer:
shortest: 33 feet
second: 66 feet
third: 58 feet
Step-by-step explanation:
s = shortest side (33)
2s = second side (66)
25 + s = third side (58)
157 = s + 2s + 25 + s
157 = 4s + 25
4s = 132
s = 33

A.In this situation,which quantity is dependent and which is
independent? Justify your answer.
B.Eight friends want to go see a movie.what would the total cost be,explain how u found the answer.
Answer:
A) y or total cost is the dependent variable and x which is the number of movie tickets is the independent variable. Y is called dependent because its value depends on the value of x.
B) So 8 is the number of tickets which is X. So x=8. The total cost y will be: 8x9= 72

Answer
A) 30 degrees
B) 60 degrees
C)120 degrees
D) 150 degrees
Answer: D) 150 degrees
Step-by-step explanation:
Opposite angles in a parallelogram are equal so, if angle D is 30 degrees, angle F is also 30 degrees. This adds up to 60 degrees.
A parallelogram is a quadrilateral so the total of its angles is 360 degrees.
Subtract 60 degrees from 360 = 300
Angles E and G will be 300 divided by 2 so E is 150 degrees.
