Al's Cardboard produces cereal boxes and uses the expression 16x2+56x+24 to determine the volume of each box. The cereal box below was produced by Al's Cardboard and has a width of 8 centimeters (cm).
Answer:(8x+24)(2x+1)
Step-by-step explanation: I dont know if im right but i think if the equation was 8(x-3)(2x+1) so if I distributed then the answer turnt out to be (8x+24)(2x+1) so im guessing thats the answer.............(8x+24)(2x+1) equals 16x^2+56x+24
Answer:
(8x+24)(2x+1)

A pasta recipe calls for 2 tablespoons of water for every 3 eggs. Using this
ratio how many eggs would be needed if the recipe called for 16
tablespoons of water?
Answer:
24 Eggs
Step-by-step explanation:
So, we're given that you need 2 tablespoons water per 3 eggs, so that's the ratio that we can set up of tbsp water to eggs. The ratio is 2:3, meaning that for every 2 tbsp of water, there's 3 eggs. Now, we're told that there's 16 tablespoons of water, so with the ratio we just got, we divide 16 by 2 and multiply 3 by the answer of 16/2. 16/2=8, and 8x3=24.
Answer:
24

3(x+4) - 2 = 2(2x + 5) - X
Answer:
3(x+4)-2=2(2x+5)-x
3x+12-2=4x+10-x
3x+10=3x+10
Any value of x
makes the equation true.
All real numbers
Interval Notation:
(−∞,∞)
Step-by-step explanation:
3x+10=3x+10 => 0=0
When x=1 => 13=13
....................................
x=5 => 25=25
......................................
Equation is always true for all x

Stella deposited $6,000 at 5% simple interest. How long will it take her before she has $8,400 in her account?
Jose interviewed for two different sales positions at
competing companies. Reliable Robotics has offered
Jose a salary of $31,200 per year plus a 9%
commission on his total sales. Robot Renegades offers
him $26,000 per year salary plus a 15% commission on
total sales for the year.
Write two linear equations, one for each offer, for the
annual pay y that Jose can make based on weekly
sales x.
Jose isn't sure which offer to accept. He likes both
companies so it comes down to the better offer. Jose is
pretty sure he can make at least $2000 sales a week.
Recommend to Jose which job he should take
considering his estimation of $2000 a week.
Answer:
Reliable Robotics: .09x+31200
Robot Renegades: .15x+26000
If Jose does 2000 sales a week this means that Robot Renegades is the better offer
Step-by-step explanation:
Reliable Robotic's offer can be modeled through the following equation
.09x+31200
And for robot renegades it's
.15x+26000
If we plug in 2,000 and multiply by 52 (to see how many sales he makes a year) into x we get
.09*2000*52+31200=40560
.15*2000*52+26000=41600
This obviously means that reliable robotics is the better offer
Answer:
the answer is B

This means function A has a greater y-intercept because 7 > 4
1) Identify the sides
2) Identify the trig ratio that you need
3) On your calculator input to find the length AB
Answer:
Please check the explanation.
Step-by-step explanation:
Given
The angle Ф = 42°
The hypotenuse = 15 cm
To determine
The length AB = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
In our case:
The adjacent to the angle Ф = 42° is the side ABso substituting Ф = 42°, adjacent = AB, hypotenuse 15 in the trigonometric ratio
cos Ф = adjacent / hypotenuse
cos 42° = AB / 15
AB = 15 × cos 42°
AB = 11.14 cm
Therefore, the length of the side AB = 11.14 cm
About \frac{3}{8}3 8 of the business calls that Ms. Rodriguez makes are long distance calls. How many business calls would you expect her to make in a month when she makes 32 long distance calls? Write an equation to find the total number of calls Ms. Rodriguez makes in a month.
[tex]\frac{3}{8}x = 32[/tex]
multiply both sides by the reciprocal
x = 85⅓
We would expect her to make about 85 business calls in a month.
Step-by-step explanation:
The equation means "3/8 of the unknown total is 32"
When we multiply 3/8 by its reciprocal, it becomes 1 and cancels on the left.
8/3 times 32 is a mixed number, so it is reasonable to round it to a whole number of calls.

Create a frequency chart of the data
below using 2 - 4 as your first interval:
5, 3, 8, 4, 2, 5, 6, 2, 7, 4, 9, 10, 3
What's the frequency for
data values 5 - 7?
A. 4
B. 6
C. 3
D. none of the above
Answer:
A. 4
Step-by-step explanation:
In this question first form a frequency table where you have a section for the class intervals and another section for the frequency. Then select the value for the frequency that is located where the interval is 5-7. The interval will start with 2-4 and increase by 2 in to the next class interval. The sum of frequency should add to the number of data set given.

Eliana bought 1/6 of a pound of green grapes and 1/12 of a pound of red grapes. How much more did the green grapes weigh than the red grapes?
Answer:
1/12 more pounds of green grapes
Step-by-step explanation:
First, we would need to find a common denominator. 6 and 12 have 12 in common, so lets pick 12 as our common denominator.
Since 1/12 already has 12 for a denominator, we wont have to do anything to it.
So, what times 6 gives you a denominator of 12? 2! If we multiply the denominator by 2, we have to also multiply the numerator by 2. 1/6 times 2/2 is 2/12.
Laslty, we have to subtract them. 2/12 - 1/12 is 1/12. so, Eliana bought 1/12 more pounds of green grapes than red grapes.
Kenny had 3/5 pan of crispy rice treats. She sent 1/3 of the treats to school. What fraction of the whole pan did she send to school?
Answer:
1/3 of 3/5 = 1/5
Step-by-step explanation:
She had 3/5 pan of crispy rice treats and sent 1/3 of the treats to school.
The fraction of the whole pan that she sent to school will be calculated by
1/3 of 3/5
= 1/3 * 3/5
=1*3/3*5
= 3/15 = 1/5

The sales tax is 4.512%. The price for the Atari is $200. What is the total cost of the Atari with sales tax included?
Answer:
$209 approx
Step-by-step explanation:
Step one:
given data
The sales tax is 4.512%
The price for the Atari is $200
Step two:
let us find the amount of the tax
= 4.512/100*200
=0.04512*200
=$9.024
Then total will be
Total= 200+9.024
Total=$209 approx
