Answer:
$0.68 per pound
Step-by-step explanation:
The price of sugar is $0.68 per pound.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, the person paid $8.16 for 12 pounds of sugar.
Therefore, mathematically it can be written as:
12 pounds of sugar = $8.16
1 pound of sugar = $(8.16/12)
1 pound of sugar = $0.68
Hence, the price of sugar is $0.68 per pound.

Answer:
120 pounds
Step-by-step explanation:
15 boxes = 45 pounds
45/15= 3
1 box= 3 pounds
40 x 3 = 120
40 boxes would weigh 120 pounds
hope this helps :)
Answer: 120 lbs.
Explanation: One box weighs 3 pounds (divide 45 by 15). 3 times 40 equals 120. So the total weight is 120 pounds.

How is solving literal equations like solving equations in one variable
Answer:
When given a literal equation, you will often be asked to solve the equation for a
given variable. The goal is to isolate that given variable. The process is the same
process that you use to solve linear equations; the only difference is that you will
be working with a lot more letters, and you may not be able to simplify as much as
you can with linear equations. This packet will hopefully show you the process in a
simple manner so that you will be able to solve literal equations yourself. See
examples before for the method to solving literal equations for a given variable:
Answer:
Step-by-step explanation:
To solve a literal equation means to rewrite the equation so a different variable stands alone on one side of the equals sign. We have to be told for which variable we want to solve.
Linear equations in one variable may take the form a x + b = 0 \displaystyle ax+b=0 ax+b=0 and are solved using basic algebraic operations. We begin by classifying linear equations in one variable as one of three types: identity, conditional, or inconsistent. An identity equation is true for all values of the variable.

Complete question :
Michael took 12 tests in his math class. his lowest score was 78. his highest score was 98. on the 13th test, he earned a 64. put a check in the correct box to indicate whether the value of each statistic below for his test scores increased, decreased, or cannot be determined when the last score was added.
1. Standard deviation 11) Median 111) Mean
Answer:
Standard deviation - increased
Median - cannot be determined
Mean - decrease
Step-by-step explanation:
The standard deviation will increase because the new (13th) test score does not fall within the range (lowest and highest) of the 12 previous test scores and will hence further increase the variability of the s ires measured
The Median cannot be determined as we need the data for the scores in other to determine the middle value of the test scores.
The mean value will decrease further because, when a score (64) lower that the previously recorded least score (78) is recorded and then the sum is recalculated and average taken. This low new score will cause the new to decrease further than previously recorded.
The value of the mean decreases, the median cannot be predicted, and the value of the standard deviation increases.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.
Michael to 12 tests in his math class.
His lowest test score was 78.
His highest test score was 98.
On the 13th Test, he earns a 64.
Then the mean will decrease because he earns a 64 on the 13th test. That is lower than his lowest score.
The standard deviation will increase because the gap between the mean and 64 will increase.
The Median cannot be determined as we need the data for the scores in other to determine the middle value of the test scores.

Consider a geometric sequence with a first term of 4 and a fourth term of -2.916.
a) Find the common ratio of this sequence.
b) Find the sum to infinity of this sequence.
Answer:
a) Find the common ratio of this sequence.
Answer: -0.82
b) Find the sum to infinity of this sequence.
Answer: 2.2
Step-by-step explanation:
nth term in geometric series is given by [tex]4\ th \ term = ar^n-1\\-2.196 = 4r^{4-1} \\-2.196/4 = r^{3} \\r = \sqrt[3]{0.549} \\r = 0.82[/tex]
where
a is the first term
r is the common ratio and
n is the nth term
_________________________________
given
a = 4
4th term = -2.196
let
common ratio of this sequence. be r
[tex]4\ th \ term = ar^n-1\\-2.196 = 4r^{4-1} \\-2.196/4 = r^{3} \\r = \sqrt[3]{-0.549} \\r = -0.82[/tex]
a) Find the common ratio of this sequence.
answer: -0.82
sum of infinity of geometric sequence is given by = a/(1-r)
thus,
sum to infinity of this sequence = 4/(1-(-0.82) = 4/1.82 = 2.2

Evaluate 4(3-1)² i need help with this
Answer:
16
Step-by-step explanation:
You can use PEMDAS to answer this question.
So first you would do whats inside the parenthesis.
4(3-1)².
3-1 is 2 so 2 would be in the parenthesis. Next you have to do exponets.
4(2)².
2² is 4. So now you just have a multiplication problem left.
4(4) which is 16.
A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft from the water in 2000. In what year will the house be only 250 ft from the water?
a. 1990
c. 2015
b. 2004
d. 2050
We develop an equation for the given situation by first writing the general equation for lines,
y = mx + b
Substituting to this given the values given above,
(1990) 430 = b
(2000) 400 = m(10) + 430
The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,
y = -3x + 430
Answer:

900 ÷ 10 = 10x ÷ 10
90 = 1x
90 = x

Volume of solution, v = 50.0 mL
What to find:
The mass/volume percent.
Solution
The mass/volume percent of the solution can be calculated using the formula below
The mass/volume percent = mass/volume x 100%
so, we get,
The mass/volume percent
= 16/50 x 100%
= 32%

One model for car depreciation is as follows, where Cis the original cost, Vis the value of the car after tyears, and ris the rate
of depreciation
V= (1-1)
If the original cost of the car was $21,000 and the rate of depreciation is 15%, what will be the value of the car after 5 years?
[Round to the nearest dollar.]
A. $17,850
B. $3,150
C. $9,318
D. $19,472
Given:
Original cost of car = $21000
Rate of depreciation = 15% = 0.15
Time = 5 years
To find:
The value of car after 5 years.
Solution:
Consider the model for car depreciation is
[tex]V=C(1-r)^t[/tex]
where, C is the original cost, V is the value of the car after t years, and r is the rate of depreciation.
Substitute C=21000, r=0.15 and t=5 in the above model.
[tex]V=21000(1-0.15)^5[/tex]
[tex]V=21000(0.85)^5[/tex]
[tex]V=21000(0.4437)[/tex]
[tex]V=9317.7[/tex]
[tex]V\approx 9318[/tex]
The value of car after 5 years is $9318. Therefore, the correct option is C.

How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Then suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
WE have been given a recipe for ice cream calls for 56 fluid ounces of milk.
We need to find How many pints of milk are there in the recipe.
There are 16 fluid ounces in 1 pint then;
56 ÷ 16
= 3.5
