system of equations means that we have a given number of equations with the same solutions.
If you only have tables, this means that you need to have one table for each equation:
For example, if you are working only with two variables, x and y, in those tables you can see the pints (x, y) that belong to each equation.
Now, a point (x, y) will be a solution of the system of equations only if it belongs to the data table for each equation
This would mean that if you graph those data sets, the graphs will intersect at the point (x, y) that belongs to all the tables of data.
another way may be using the data in the tables to construct the equations, but you said that you only want to use the tables, so this method can be discarded.

Gabriel deposits $400 into a
savings account in January
If he deposits 5% more each
month, what is the amount,
to the nearest dollar, of his
December deposit?
Answer:
640
Step-by-step explanation:
5% of 400 is 20
20 x 12 is 240
400 + 240 = 640
Forgive me if I'm wrong. I suck at math XD
The amount for the month of December is $640.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Gabriel deposits $400 into a savings account in January If he deposits 5% more each month.
The December month deposit is calculated as,
5% of 400 is 20
20 x 12 is 240
400 + 240 = $640
Therefore, the amount for the month of December is $640.

middle school has 600 students and 34% of them are in the 8th grade. One-fourth of 8th graders walk to school. How many 8th grade students walk to school? A. $4.50 B. $9.00 C. $12.00 D. $48.60
Answer: 51 students
Step-by-step explanation:
There are 600 students in this school and 34% are in 8th Grade.
The number of students in 8th grade is:
= 34% * 600
= 204 students
Then out of these 204, 1/4 walk to school. The number of students walking to school is therefore:
= 204 * 1/4
= 51 students

I divided 6394 by 42 but I don’t know the remainder. Does it have one or not?
Answer:
The answer is 152 r10
Step-by-step explanation:
There is indeed a remainder when dividing 6394 by 42.
6394 ÷ 42 = 152 with a remainder of 10, so, the remainder is 10.
Here, we have,
To determine if there is a remainder when dividing 6394 by 42,
we can perform the division and check if the result is a whole number or a decimal.
6394 ÷ 42 = 152 with a remainder of 10
Since the division does not result in a whole number,
but rather a quotient of 152 with a remainder of 10,
it indicates that there is indeed a remainder when dividing 6394 by 42.

At an ice carving competition, each carver starts with a block of ice with the dimensions shown. The block is wrapped in a special reflective material to keep it from melting before the competition starts.
Answer:
52 square feet
Step-by-step explanation:
Given
See attachment for block
Required
How much reflective material is needed (without overlapping)
The question implies that, we calculate the surface area of the material.
Without overlapping, the material will have the same surface area as the block of ice.
The surface area is calculated using:
[tex]SA = 2 * (LW + WH + HL)[/tex]
Where
[tex]W = 4[/tex] --- Width
[tex]L = 2[/tex] --- Length
[tex]H = 3[/tex] --- Height
So, we have:
[tex]SA = 2 * (2 * 4 + 4 * 3 + 3 * 2)[/tex]
[tex]SA = 2 * (8 + 12 + 6)[/tex]
[tex]SA = 2 * 26[/tex]
[tex]SA = 52[/tex]

Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not. Considering this data, how many of the next 6 pizzas sold would you expect to have pepperoni?
Answer:
1 pizza
Step-by-step explanation:
Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not.
This means, the total number of pizzas sold is
10 pepperoni + 2 pizzas without pepperoni = 12 pizzas
Hence, the number of 6 pizzas that would be sold without pepperoni is calculated as:
From the above question,
12 pizzas = 2 pizza without pepperoni
6 pizzas = x
Cross Multiply
12 pizzas × x = 6 Pizzas × 2 pizza without pepperoni
x = 6 Pizzas × 2 pizza without pepperoni/12 pizzas
x = 1 pizza without pepperoni
Therefore, 1 pizza would not have pepperoni out of 6 pizzas sold

Answer:
508sq. cm
Step-by-step explanation:
surface area of a prism = 2(lw + wh + lh)
For the larger prism
Surface area = 2(2*10 + 2 * 12 * 10*12)
Surface area = 2(20+24+120)
Surface area = 2(164)
Surface area = 328sq.cm
For the smaller prism
Surface area = 2(3*6 + 3 * 8 * 6*8)
Surface area = 2(18+24+48)
Surface area = 2(90)
Surface area = 180 sq.cm
Surface area of the figure = 328 + 180
Surface area of the figure = 508sq. cm

Problem Set
1. A 5-liter cleaning solution contains 30% bleach. A 3-liter cleaning solution contains 50%
bleach. What percent of bleach is obtained by putting the two mixtures together?
5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.
3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.
Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is
(3 L) / (8 L) = 0.375 = 37.5%
There are 520 employess at greenville publishing. Jasmine surveys a representative sample of employees on their transportation costs each month. The reults are shown in the box plot.
Answer:
130 ; 50% ; 25%
Step-by-step explanation:
Using te boxplot to answer the underlying questions :
Number of employees who spend $10 or less corresponds to the lower quartile, which is up to 25% of the distribution :
Total number of employees = 520
Number of employees who spend $10 or less = 25% of 520 = 0.25 * 520 = 130 employees.
Percentage of employees who spend from $10 to $45 = Interquartile range
$10 corresponds to lower quartile = 25%
$45 corresponds to upper quartile = 75%
IQR = 75% - 25% = 50%
Percentage who spend $45 or more
$45 corresponds to the upper QUARTILE (Q3) :
45 or more = 100% - Q3 = 100% - 75% = 25%
Wanda uses 3.54 cups of flour to make 6 bagels. Eli uses 2.5 cups of flour to make 5 bagels. How much more flour per bagel is needed for Wanda's recipe?
Answer:
Wanda's recipe needs 0.09 more cups of flour per bagel.
Step-by-step explanation:
First, you have to find the amount flour that each of them need for one bagel by dividing the cups of flour they use by the number of bagels:
Wanda: 3.54/6= 0.59 cups of flour
Eli: 2.5/5=0.5 cups of flour
Now, you have to subtract the amount of flour Eli needs from the amount that Wanda needs:
0.59-0.5=0.09
According to thiss, the answer is that Wanda's recipe needs 0.09 more cups of flour per bagel.
The Blue Diamond Company advertises that their nut mix contains (by weight) 40% cashews, 15% Brazil nuts, 20% almonds and only 25% peanuts. The truth-in-advertising investigators took a random sample (of size 20 lbs) of the nut mix and found the distribution to be as follows: 5 lbs of Cashews, 6 lbs of Brazil nuts, 5 lbs of Almonds and 4 lbs of Peanuts. At the 0.05 level of significance, is the claim made by Blue Diamond true? Select the [p-value, Decision to Reject (RH0) or Failure to Reject (FRH0)].

What is Chi- square test?A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test that is valid to perform when the test statistic is chi-squared distributed under the null hypothesis, specifically Pearson's chi-squared test and variants thereof. Pearson's chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table.
The data is given as follow:
The experimental weight of cashews = 40 % of 20lbs
= 8
The experimental weight of Brazil Nuts = 15 % of 20lbs
= 3
The experimental weight of Almonds = 20 % of 20lbs
= 4
The experimental weight of peanuts = 25 % of 20lbs
= 5
The observed value is :
Cashews = 5Brazil Nuts= 6Almonds= 5Peanuts= 4So, [tex]{\displaystyle \chi }[/tex] =[tex]\frac{(O-E)^{2}}{E}[/tex]
[tex]{\displaystyle \chi }[/tex]= [tex]\frac{(5-8)^{2}}{8} + \frac{(6-3)^{2}}{3} + \frac{(5-4)^{2}}{4} +\frac{(4-5)^{2}}{5}[/tex]

Condense (cos92°)(cos133°)-(sin92°)(sin133°) into a singular trigonometric function expression, then find the exact value.
Answer:
-1/√2
Step-by-step explanation:
According to trigonometry identity
cos(A+B) = cosAcosB - sinA sinB
Given the expression
(cos92°)(cos133°)-(sin92°)(sin133°)
This can be expressed as cos(92+133) where A = 92, B = 133
(cos92°)(cos133°)-(sin92°)(sin133°)
= cos(92+133)
= cos225
= -0.7071
= -1/√2
Hence the exact value is -1/√2
