1 pound = 16 ounces.
1 can weighs 8 ounces, so 2 cans weigh 8 +8 = 16 ounces, which is 1 pound.
Multiply total pounds by number of cans per pound:
25 pounds x 2 cans per pound = 50 total cans.
The number of cans each box hold will be 50.
How to convert ounces to pounds?In one pound there is a total of sixteen ounces.
So it means 1 pound = 16 ounces.
Given that the weight of the can is 8 ounces it means in 2 cans there are 16 ounces which are 1 pound.
2 cans = 1 pound
Since, the box can hold only 25 pounds Hence,
25 × 2 = 50 cans so a box can hold up to 50 cans.

PLZZZZ GEOMETRY HELP solve for HI
Answer:
2 units
Step-by-step explanation:
ok, so, the line below says HJ is (x+1) units long. therefore:
2x-16+8 = x+1
now, let's isolate the variable.
2x-x = 1+16-8
x = 9
since we now defined variable x, we can add it to the equation that determines the length of HI.
2x-16
2(9)-16
18-16
2
the length of line segment HI is 2 units
hope this helped!
HI + IJ = HJ
With this knowledge you can from an equation like so...
2x - 16 + 8 = x + 1
Now combine like terms and solve for x
2x + (- 8 + 8) = x + 1 + 8
2x = x + 9
2x - x = x - x + 9
x = 9
To find HI plug 9 in for x and simplify
2(9) - 16
18 - 16

The length of HI is 2!!!
Hope this helped!

Which of the following is the equation of a line parallel to the line y = 3x + 2,
passing through the point (10.1)?
A. -3x - y = 29
B. 3x - y = 29
C -3x + y = 29
D. 3x + y = 29
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (10, 1) into the partial equation
1 = 30 + c ⇒ c = 1 - 30 = - 29
y = 3x - 29 ← in slope- intercept form
Subtract y from both sides
0 = 3x - y - 29 ( add 29 to both sides )
29 = 3x - y, thus
3x - y = 29 ← in standard form → B

A quilt is designed using a square pattern. Each square contains two rectangles. Each rectangle contains a shaded rhombus.
What is the value of x?
50
55
125
145
Answer:
The value of x is 55 ⇒ 2nd answer
Step-by-step explanation:
* Lets revise the properties of the rhombus
- It has 4 equal sides
- Every two opposite sides are parallel
- Every two opposite angles are equal
- Every two adjacent angles are supplementary (their sum is 180°)
* Now lets solve the problem
- A square divided into two rectangles
- Each rectangle contains a shaded rhombus
- The shaded rhombus has two adjacent angles their measures are
(2x + 20)° and 50°
∵ Every two adjacent angles in the rhombus are supplementary
∵ The sum of the supplementary angles = 180°
∴ The sum of the measures of the angles (2x + 20)° and 50° is 180°
- lets put the equation and solve it to find x
∴ (2x + 20)° + 50° = 180° ⇒ add the like terms
∴ 2x + 70° = 180° ⇒ subtract 70° from both sides
∴ 2x = 110° ⇒ divide both sides by 2
∴ x = 55°
* The value of x is 55
A walking path across a park is represented by the equation y=-2x+5. A
new path will be built perpendicular to this path. The paths will intersect at
the point (-2,9). Identify the equation that represents the new path.
A. y= {x+10
B. y= -2x - 5
C. y= 2x+13
D. y -- 1x+8
Answer:
[tex]y = \frac{1}{2}x+10[/tex]
Step-by-step explanation:
The given path is:
y = -2x+5
Comparing with the standard form of equation:
y = mx+b
So,
m = -2
We know that product of slopes of two perpendicular lines is -1
Let m1 be the slope of the perpendicular line
m*m1=-1
-2*m1 = -1
m1 = -1/-2
m1 = 1/2
So the slope of perpendicular path is 1/2.
Since the new path passes through (-2,9)
[tex]9 = \frac{1}{2}(-2) +b\\9 = -1 +b\\b = 10[/tex]
Putting the values of m and b in standard form
[tex]y = \frac{1}{2}x+10[/tex]
Hence the equation of new path is:
[tex]y = \frac{1}{2}x+10[/tex] ..
an equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.
Answer:
y = (-1/2)x -3
Step-by-step explanation:
We are given
y = 2x-17
which is in slope-intercept form: y = mx +b
Where m is the slope. so, m= 2
But this is perpendicular, When a line is perpendicular then the slope become -1/m so in our case the slope m will be = -1/2
Using the point(-8,1) we can find the b i.e the y intercept
We have x = -8, y =1 and m=-1/2
y = mx + b
1 = (-1/2)(-8) + b
1 = 4 + b
=> b = 1-4
b = -3
The equation of slope intercept form will be
y = mx + b
Putting value of m= -1/2 and b = -3
y = (-1/2)x -3

A. 2w + 3
B. 2(w + 3)
C. 3(2w)
Answer:
2W+3 I am really sorry if that's wrong, I don't think it is though GOODLUCK
Step-by-step explanation:
Answer:
The correct answer is option A. 2w + 3
w = 5 inches
Step-by-step explanation:
It is given that, the length of a rectangle is 3 inches more than twice its width, and its area is 65 square inches.
To find the correct option
If 'w' is the width of rectangle, then length = 3 inches more than the twice the width
length = 2w + 3
The correct answer is option A. 2w + 3
To find the width
We have area = 65 square inches
Length * Width = 65
(2w + 3) * W = 65
2w² + 3w - 65 = 0
Solving we get ,
w = 5 and -6.5
Therefore w = 5 inches

Which are possible first steps in solving the equation 4x + 3 = 18?
Answer:
C D and E
Step-by-step explanation:
The only one you probably can never do is B. It get's you no where. The way A is written, it is not much help to write 18 in base 2. So A and B both won't work. The common logs and the natural logs will both work
Log(4^(x + 3)) = Log(18)
(x + 3) Log(4) = log (18)
(x + 3) * 0.6021 = 1.2553
x + 3 = 1.2553/0.6021
x + 3 = 2.08496
Now all you need do is subtract 3 from both sides. The natural logs will give you the same answer.
You could take base-4 logs of both sides and it is a possible first step, but d and e are much more efficient. You have to change both sides to base 4 before you can proceed. This one is kind of iffy. It does say possible first steps.
Answer:
C.Take the base-4 logarithm of each side.
D.Take the natural logarithm of each side.
E. Take the common logarithm of each side.
Step-by-step explanation:
A teacher wanted to buy a chair, a bookshelf, two tables and a desk. She spent $900 for all five items and the chair and the desk combined 70% of her total. If the bookshelf cost $50, how much did each of the tables cost?
Find the cost of the chair and desk by multiplying the total amount pent by the 70%
Chair and desk = 900 x 0.70 = $60
Subtract that cost from the total spent:
900 - 630 = $270 was spent on the other three items.
Subtract the cost of the bookshelf:
270 - 50 = 220
The two tables cost 220.
For the price of one table divide that cost by 2:
220/2 = 110
One table cost $110.
The cost of each table is $110.
Given that
There are five items i.e. chair, bookshelf, 2 tables, and a desk.
The total amount incurred for these 5 items should be $900.
And, the chair + desk = 70% of total.
The cost of the bookshelf is $50.
Since 70% of total = chair + desk
That means
Chair + desk = 0.70 of $900 = $630
So the other items cost should be
= $900 - $630
= $270
And, the cost of bookshelf is $50
So, the two tables cost should be
= $270 - $50
= $220
So for one it should be
= $220 ÷ 2
= $110
Therefore we can conclude that the cost of each table is $110.

Use the properties of exponents to rewrite the expression.
(-5uv)(-5uv)(-5uv)(-5uv)
The expression can be simplified to [tex]625 \times (uv)^4.[/tex]
To rewrite the expression (-5uv)(-5uv)(-5uv)(-5uv) using the properties of exponents, you can consolidate it using the exponent rule that states when you multiply numbers with the same base, you add the exponents. In this case, the base is -5uv, and you are multiplying it four times, so the exponent is 4:
[tex](-5uv)(-5uv)(-5uv)(-5uv) = (-5uv)^4[/tex]
Now, you can simplify further by applying the rule for raising a power to a power, which states that when you raise an exponentiated term to another exponent, you multiply the exponents:
[tex](-5uv)^4 = -5^4 \times (uv)^4[/tex]
-5^4 means -5 multiplied by itself four times:
[tex]-5^4 = -5 \times -5 \times -5 \times -5 = 625[/tex]
So, the expression can be simplified to:
[tex]625 \times (uv)^4[/tex]
This is the expression rewritten using the properties of exponents.

Aaron bought a new television that has a 92 in. 76 in. screen. It has a feature that splits the screen to allow him to watch 4 channels at once. What is the scale factor and size for each channel when this feature is turned on? (SHOW WORK)
Answer:
The scale factor is equal to 1/2
The dimensions of each channel when splits the screen is 46 in x 38 in
Step-by-step explanation:
we know that
The dimensions of the new television is 92 in x 76 in
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
A1 -----> the area of the new television
A2 ----> the area of each channel when splits the screen
z-----> the scale factor
[tex]z^{2} =\frac{A2}{A1}[/tex]
we have that
The area of the new television is 4 times the area of each channel
[tex]A1=4A2[/tex]
[tex](A2/A1)=1/4[/tex]
[tex]z^{2} =\frac{1}{4}[/tex]
[tex]z=\frac{1}{2}[/tex] -----> the scale factor
so
When splits the screen, the dimension of each channel is equal to
92/2 in x 76/2 in
so
46 in x 38 in
Remember, if two figures are similar then the scale factor is equal to the ratio of their corresponding sides
Verify the value of the scale factor
92/46=1/2

Write the first five terms of the arithmetic sequence whose first term is 5 and whose common difference is 6.
Answer:
5, 11,17,23,29
Step-by-step explanation:
To obtain the term in the sequence add the common difference to the previous term, that is
a(1) = 5
a(2) = 5 + 6 = 11
a(3) = 11 + 6 = 17
a(4) = 17 + 6 = 23
a(5) = 23 + 6 = 29
The first five terms of an arithmetic sequence starting with 5 and a common difference of 6 are 5, 11, 17, 23, and 29.
The first five terms of the arithmetic sequence with the first term 5 and a common difference of 6 can be found by successively adding the common difference to the previous term.
Third term (a3) = a2 + 6 = 11 + 6 = 17
Fifth term (a5) = a4 + 6 = 23 + 6 = 29
Therefore, the first five terms of the arithmetic sequence are 5, 11, 17, 23, and 29.

What are the slope and the y-intercept of the linear function that is represented by the table?
Answer:
slope rise 3 run 2 1/2
Step-by-step explanation:
if you start from the bottom and if you start from the top it's -3 and -2 1/2
Answer: The slope is 3 and the y-intercept is 3/2
Step-by-step explanation:
The slope of a linear function can be calculated as:
s = (y2 - y1)/(x2 - x1)
Where y2 = f(x2) and y1 = f(x1) and f(x) is the linear function.
So here we can use any two pairs of the set of data, for example, the first two.
(-1 , -3/2) and (-1/2,0)
s = (0 -(-3/2))/(-1/2 - (-1)) = (3/2)/(1/2) =(3/2)*(2/1) = 3
So the slope is equal to 3.
the y-intercept is the value of y when x = 0, in the table we can see that when x = 0. the value of y = 3/2
So the function is: y = 3*x + 3/2
and the correct option is the fourth one.
