The surface are of the new solid formed by the joining of two identical cubes having a surface area of 294 cm² is: 490 cm²
What is the Total Surface Area of a Cube?Total surface area of a cube = 6a², where a is the length of each of the sides.
Given:
Surface area of each identical cube = 294 cm²
Find the length of each side:
6a² = 294
a² = 294/6
a² = 49
a = √49
a = 7 cm
Surface area of the new solid = surface area of the two identical cubes - 2(area of the surface where both are joined)
Surface area of the new solid = 2(294) - 2(7²) = 490 cm²

A recipe says to use 3.5 cups of flour to make 48 cookies. What is the constant of proportionality that relates the number of cookies made, y, to the number of cups of flour used, x. Round your answer to the nearest tenth.
Answer: 0.07 cups/cookie
Step-by-step explanation:
The Constant of proportionality is the measure by which the number of cookies made, y increases to the number of cups of flour used, x.
If 3.5 cups of flour makes 48 cookies then how many cookies does 1 cup make;

Answer:
[tex]\angle {1} = 90\\\angle {2} = 45\\\angle {3} =55[/tex]
Step-by-step explanation:
1 is 90 because it's placed onto a straight line the equals 180 degrees, therefore it's 90 because the other 2 angles with it are the same, meaning that they had to be 45. 3 is 55 because 90+35=125, and the sum of all 3 angles in a triangle must equal 180, therefore 180-125=55.

Answer:
option A is correct
75 − s = c
20s + 30c = 1,870
Step-by-step explanation:
The question is not complete.
Here is a complete form
"A software company is selling a new game in a standard edition and a collector's edition the box of the standard edition has a volume of 20 cubic inches and the box for the collector's edition has a volume of 50 cubic inches 30 cubic inches the company received an order for 75 copies of the game, and the total volume of the order to be shipped is 1,870 cubic inches. Which of the following systems of equations can be used to determine the number of standard edition games, s, and collector’s edition games, c, that were ordered?"
s+c=75
75 − s = c
20s + 30c = 1,870
the options are
A. 75 − s = c
20s + 30c = 1,870
B. 75 − s = c
30s + 20c = 1,870
C. s − c = 75

We found in the previous task, that Chef Walton cooked 50 meals first. However, for the next dinner service, Chef Barber prepared 14 meals ahead of time, instead of 7. What will be the effect of Chef Barber's new initial value? Check all that apply.
Answer:
Chef Barber will now cook 50 meals first and The new y-intercept will change the result.
Step-by-step explanation:
I just did on edge
Given question is incomplete without options and the information regarding the cooking of two chefs; Find the compete question in attachment.
Options for the question are,
A). Chef Walton will still cook 50 meals first.
B). Chef Barber will now cook 50 meals first.
C). The new y-intercept will have no effect.
D). The new y-intercept will change the results.
Options B and D are the correct options.
Given in the question,
Chef Walton cooked 50 meals first.Chef Barber prepared 14 meals ahead of time, instead of 7.From the picture attached,
Chef Barber prepared 7 meals before the dinner and must prepare 13 meals per hour during dinner.So the equation for the total meals 'y' prepared in 'x' hours by chef
Barber will be,
y = 13x + 7
Therefore, duration for 50 meals to be prepared,
50 = 13x + 7
x = 3.62 hours
If Chef Barber prepared 14 meals before dinner service,
Equation for the meals prepared will change to,
y = 13x + 14
New time to prepare for 50 meals,
50 = 13x + 14
x = 2.77 hours
2. From the graph given in the picture,
Slope of the line between two points (0, 4) and (3, 49),
m = [tex]\frac{49-4}{3-0}[/tex]
m = 15
Here, slope of the line defines number of dishes prepared per hour by
Chef Walton.
Chef Walton prepared 4 dishes before the dinner service,
y = 15x + 4
Time taken to prepare 50 meals,
50 = 15x + 4
x = 3.07 hours
Now check the options given,
Option A
"Chef Walton will still cook 50 meals first.
Since, new time taken by Chef Barber (2.77 hours) is less than the time taken by Chef Walton (3.07 hours),
Option A is false.
Option B
"Chef Barber will now cook 50 meals first"
True.
Option C
"The new y-intercept will have no effect"
False.
Option D
"The new y-intercept will change the results"
True.
Therefore, Options B and D will be correct.

If ST=w–47 and RU=w–63, what is the value of w?
Answer:
w = 79
Step-by-step explanation:
We know that RU us a midsegment so it must be 1/2 of ST.
So ST = 2RU.
w-47 = 2(w-63)
w-47 = 2w-126
-w = -79

Given:
7 relations are given.
To find:
The relation which is not a function.
Step-by-step explanation:
A relation is called function if there exist unique output for each input.
It means, each x-value has only one y-value.
{(1, 3), (3, 7), (5, 11), (7, 15), (9, 19)}, it is a function.
{(1, 3), (1, 7), (5, 11), (5, 15), (9, 19)}, it is not a function because there exist two y-values y=3 and y=7 at x=1.
{(−2, 4), (−1, 1), (0, 0), (1, 1), (2, 4)}, it is a function.
{(2, 4), (1, 1), (0, 0), (1,−1), (2, −4)},it is not a function because there exist two y-values y=4 and y=-4 at x=2.
{(6, 3), (4, 1), (2, 1), (0,−1), (−2,−3)}, it is a function.
{(1, 3), (3, 7), (3, 11), (7, 15), (9, 19)}, it is not a function because there exist two y-values y=7 and y=11 at x=3.
{(1, 3), (3, 7), (5, 11), (9, 15), (9, 19)}, it is not a function because there exist two y-values y=15 and y=19 at x=9.
Therefore, the correct options are 2, 4, 6 and 7.

A company that uses job order costing reports the following information. Overhead is applied at the rate of 60% of direct materials. The company has no beginning Work in Process or Finished Goods inventories. Jobs 1 and 3 are not finished by the end of March, and Job 2 is finished but not sold by the end of March
Based on the percentage completed and the cost of the jobs, total value of work in process inventory at the end of March is $62,480.
What is the Work in Process Inventory?The work in process will include Jobs 1 and 3 only because job 2 is already done.
Work in process can be found as:
= Cost of job 1 + Cost of job 3
Cost of a single job is:
= Direct labor + Direct materials + Overhead which is 60% of direct materials
Solving for both jobs gives:
= (13,400 + 21,400 + (13,400 x 60%)) + (6,400 + 9,400 + (6,400 x 60%))
= $62,480
