A 16-ounce bag of cereal costs about $2.88. What is the unit rade of the cereal?
Answer:
18 cents per ounce
Step-by-step explanation:
The first step is to identify the unit. In this case, you are told you have 16-ounces. Therefore, your unit is an ounce.
To find the price of one ounce, just divide your price of $2.88 by 16.
Unit rate = $2.88 / 16 = 0.18 or 18 cents per ounce.

Can yall find EB? Round the the nearest hundred. AD=8.98, AB=6.47. ABCD is a rectangle
Answer:
5.53408980773 or 5.534
Step-by-step explanation:
Let's take AD as a, AB as b and DB as c
a2+b2 =c2
(8.98)2 + (6.47) 2 =c2
80.6404 + 41.8609 =c2
The number 2 is square . take it like square
122.5049 =c2
[tex] \sqrt{c \: \: } = \sqrt{122.5049 } [/tex]
C=11.0681796155
this valse is DB but the question say EB so dividend by 2 because rectangle diagonal are equal
So EB =11.0681796155/2
EB =5.5340890773

What is a formula for the nth term of the given sequence? 48, 72, 108
Answer:
[tex]a_n=48*1.5^{n-1}[/tex]
Step-by-step explanation:
Geometric Sequence
In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
We are given the sequence:
48, 72, 108, ...
The common ratio is found by dividing the second term by the first term:
[tex]r=\frac{72}{48}=1.5[/tex]
To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.
Now we are sure this is a geometric sequence, we use the general term formula:
[tex]a_n=a_1*r^{n-1}[/tex]
Where a1=48 and r=1.5
[tex]\boxed{a_n=48*1.5^{n-1}}[/tex]
For example, to find the 5th term:
[tex]a_5=48*1.5^{5-1}=48*1.5^{4}=243[/tex]
Can someone explain how to work this out please ?
Answer:
x=4
Step-by-step explanation:
f(x) = (x-2)^5 +3
Let f(x) = 35
35 = (x-2)^5 +3
Subtract 3 from each side
35-3 = (x-2)^5 +3-3
32 = (x-2)^5
Take the fifth root of each side
32 ^ (1/5) = (x-2)^5^ 1/5
2 = x-2
Add 2 to each side
2 +2 = x-2+2
4 =x

Find the sum of the squares of 3, 2, 1, and -1
Answer:
15
Step-by-step explanation:
3 x 3=9
2 x 2=4
1x1=1
-1x-1=1
9+4+1+1=15
Answer:
15
Step-by-step explanation:
The square of 3 is 3 times 3, so 9.
2 times 2 is 4.
1 times 1 is 1.
-1 times -1 is 1, because the negative cancels out.
So, it's 9 plus 4 plus 1 plus 1, so the answer is 15.

write the equation of a line that has a m= -5 and passes through the point (-1,4)
write a paragraph describing the steps taken to find the linear equation and include the answer the the question in your response.
at least 6 sentences plz
Answer:
We have a slope and a point, this way, we do not need to find the slope using two points. We can find the line using the Slope Form to turn it into Slope-Intercept Form, also known as "y = mx + b". We can use the Slope Form which is "y - y1 = m(x - x1)". A coordinate is "(x,y)", so that means, "(-1,4)" means that x = -1 and y = 4. We can substitute y1 for 4 and x1 for -1, and m for -5 since m is the slope. Plugging that information into the Slope Form Formula we get "y - 4 = -5(x - (-1))". We know that a negative with a negative turn positive, so we can use this information to change the formula to "y - 4 = -5(x + 1)". Now we distribute and simplify, these steps are shown below.
y - 4 = -5(x + 1)
y - 4 = -5x -5
y - 4 + 4 = -5x - 5 + 4
y = -5x - 1
Now that we have simplified it, we can see that the slope is -5 and the -1 is the y-intercept. To check this is a linear equation is to graph it, or substitute three x-coordinate or y-coordinates and draw a line. In conclusion, the equations is y = -5x - 1.

there were a hundred pounds of boxes for every 54 lb of packing and if a factory used 260 lb of packing how many pounds of boxes did the
factory use
9514 1404 393
Answer:
481.5 (rounded to tenths)
Step-by-step explanation:
Boxes are proportional to packing, so we have ...
(pounds of boxes)/(pounds of packing) = b/260 = 100/54
Multiplying by 260 gives ...
b = 260(100/54) = 26000/54 = 481.481481...
About 481.5 pounds of boxes were used.

5. A cube has width of 8 cm. What is the volume of the cube?
Anyone got an answer?
Answer:
8×8×8 =512
Step-by-step explanation:
prove me wrong
Answer:
512 cm
Step-by-step explanation:
the formula to find volume is length × width + height (L×W×H) and since it is a cube all of the sides are equal so simply multiple 8 × 8 × 8 to get 512

Answer:
19/20 is the correct answer
Answer:
19/20 quart
Step-by-step explanation:
the denominator should be the same so find some thing that is common to 4 and 5 so 20 and find what 4 in to 20 go 5 times so multiply 5×3=15 and 4×1=4 so add them together 15+4 = 19 so put 19 and 20 together equal 19/20

The double number line shows how far a hummingbird can fly in 1 second -
Complete the table to show the same information as the double number line
Answer:
1
3
130
Step-by-step explanation:
as shown on the lines, it takes the bird one second to fly 13 meters. the answer to the first blank is 1
using this ratio, 13 meters per second, we can find how long it takes for the bird to fly 39 meters.
13/1=39/x
this is 13x=39
x=3 seconds
use the same ratio to find distance
13/1=x/10
13=x/10
130=x

square root of 9 multiplied by square root of 180
Answer:
18√5
Step-by-step explanation:
√9×√180
from √9 we get 3 cause 3² is 9.
from 180 we get 6√5 because √36×5 is √180.
we took 36 out because it gives us a whole number if we square root it.
So √36×5 is 6√5 , because the square root of 36 is 6
then we multiply 3 and 6√5.
3×6 is 18 so we put 18 and put the √5 behind it.

the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with
Answer:
it started off with 7 members
(read the whole explanation)
Step-by-step explanation:
Question: the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with.
If the chess club accepts 5 each week and they had 6 members after 6 weeks you should multiply 5x6=30. We don't know when the chess club started.. it could be 6 or 7 weeks ago and I'm pretty sure we all know that 7x5=35. but it only says 6 weeks ago so the answer is 7,
