Morgan is in the business of manufacturing phones. She pays a cost of $200 per phone produced for materials and labor and also must pay a daily fixed cost of $400 to rent the building and equipment. Make a table of values and then write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.
A linear equation is an algebraic equation of the form [tex]y=mx+b[/tex]. , where m is the slope and b is the y-intercept.
Total cost represented by equation, [tex]C=200x+400[/tex]
Let number of phones is represented by x .
Since, She pays a cost of $200 per phone produced for materials and labor
For x phones, she will pay = 200x
Since, she also pays daily fixed cost of $400 to rent the building and equipment
Therefore, total cost is represented by equation shown below,
[tex]C=200x+400[/tex]

Today, a bicycle rider rode her bike 5 1/2 miles to raise money for her school. Yesterday, she rode 6 1/4 miles her grandfather said he would give her 2$ for every mile she rode. How much money did she earn?
Answer:
.125 or 1/8
Step-by-step explanation:
The question is looking for the difference divided by the long ride. The long ride is 6 1/4 miles, so now we need to find the difference.
In order to do this, we take the larger distance and subtract the smaller distance.
We would take (Tip: Use decimals when you can. They are easier to work with ) 6.25 - 5.5 and we get .75 or 3/4 of a mile.
Now, we put .75 over 6.25 and simplify.
.125 or 1/8

in a school 46% of the 300 students are boys. how many girls are in the class than boy?
Answer:
138 of the students are boys, and 162 of them are girls. there are 24 more girls than boys.
Step-by-step explanation:
multiplying a number by its percent as a decimal gets you the percent of that number
300 x .46 = 138 boys
now subtract that from the original 300 to get the girls
300 - 138 = 162 girls
lastly subtract the girls from the boys to get how many more girls there are than boys
162 - 138 = 24

Which sequence of rigid motions will definitely work to take triangle GHJ onto triangle STU?
A.) Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
B.) Translate GHJ by the directed in segment GS. Translate G’H'J by the directed line segment H'T. Translate G"H"J" by the directed line segment J"T.
C.) Translate GHJ by the directed line segment GS. Rotate G’H'J using S as the center by angle H'ST Reflect G"H"J" over ST.
D.) Translate GHJ by the directed line segment GT. Rotate G’H'J using T as the center by angle H'ST. Reflect G"H"J over ST.
The correct option is A. Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
There are four types of rigid motions that we will consider translation , rotation, reflection, and glide reflection.
Here we have to rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.
Hence option A is correct that is Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Hello!! I need help with square root please help me!!!
Ok so what you need to do is you need to get all the numbers and see which one is the right number so...
A. y = 11.2 that is wrong
B. y = 25 is wrong
C. y = 5 is right
D. y = 15 is wrong.
C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!
C is correct
Hope this helps!!
Answer:
This is actually a cube root, since you need a cube root to cancel out the cube.
C, y = 5
Step-by-step explanation:
125 = 5 × 5 × 5 = 5^3
5 × 5 × 5 = 25 × 5 = 125.
Therefore the cube root of 125 = 5.
It REALLY helps when you break these into factors.
[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]
This is essentially asking what multiplied by itself three times is equal to 125.
Process of elimination can be used for any number cubed that is ≠ 125
i.e : 11.2^3 ≠ 125
11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2
I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.
And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.
how do I solve −2(n− 9) + 4 using distributive property or combining like terms?
Answer:
Multiply the term outside of the parentheses by each term in the parentheses. To do this, you are essentially distributing the outer term into the inner terms. Multiply the term outside the parentheses by the first term in the parentheses. Then multiply it by the second term. If there are more than two terms, keep distributing the term until there are no terms left. Keep whatever operation (plus or minus) is in the parentheses

How many planes pass through three or more vertices of a regular octahedron?
Answer:
The total number of planes = 23 planes
Step-by-step explanation:
The number of planes are give as follows;
The number of planes with three points, given that any three points of an octahedron forms a plane are ₆C₃ = 20
The number of distinct planes that has 4 points in the octahedron = 3
Therefore, the total number of planes are 20 + 3 = 23 planes.

The quotient

0 The product st is irrational.
The quotient is rational.
Previous
Pause
Answer:
The product st is irrational.
The product pt is irrational.
Step-by-step explanation:
Let p = 3/4 and q= 5/9
Now multiplying these two non zero rational numbers
3/4 (5/9)= 15/36 ( this is also a rational number)
An irrational number is one which cannot be expressed in the form of p/q where p and q are integers( in the form of a simple expression) like the rational number.
Now let the two irrational numbers s and t be √3 and √5
Now multiplying the two irrational numbers we get
st = √3 √5
st =√15 ( this is also an irrational number)
√15 cannot be expressed in the form of a simple fraction.
Now multiplying pt
3/4 * √5= 3√5/4 ( this is also irrational)

5 pencils and 3 pens costs £11.
4 pencils and 6 pens costs £16.
Find the cost of a pencil.
Find the cost of a pen.
Answer:
The pencil is £1 and the pen is £2
Step-by-step explanation:
Let the pencil be p and let the pen be f.
5p + 3f = 11
4p + 6f = 16
the top one multiplies by two:
10p + 6f = 22
4p + 6f = 16 subtract
6p = £6
pencil = £1
Then you substitute the value of the pencil into the equation and find the value of the pen.

I am selling 900 yearbooks, making a total of $2820. The large yearbook pages cost $4 and the small cost $2.50. Find how many of each I sold. HELPPP PLS
Answer:
number of large year book sold = 380
number of small year book sold =520
Step-by-step explanation:
Let the no. of large year book pages be x
given that
cost of 1 large year book = $4
cost of x large year book = x*cost of 1 large year book = $4x
Let the no. of small year book pages be y
given that
cost of 1 small year book = $2.5
cost of y small year book = y*cost of 1 large year book = $2.5y
also,
total year books sold were 900
no. of small year book + no. of small year book = 900
x + y = 900
y = 900 - x ------------------>1
also total money made by selling large and small year book = $2820
cost of x small year book + cost of x large year book = 2820
4x + 2.5y = 2820
using y = 900 - x in above equation
4x + 2.5(900-x) = 2820
4x + 2250 - 2.5x = 2820
1.5x = 2820-2250 = 570
x = 570/1.5 = 380
Thus,
number of large year book sold = 380
number of small year book sold = 900-380 = 520

Sonya made a resolution to walk 2.5 kilometers a day. On Tuesday she walked 4 times around the running track at the local high school (each lap is 0.4 kilometers.) How many additional kilometers does Sonya need to walk? (HINT: this is a multi-step problem with 2 operations...)
Answer:
0.9km
Step-by-step explanation:
Given that:
Sonya's resolution = walk 2.5 km daily
Total distance walked on Tuesday = 4 times around a running track
1 lap = 0.4 km
Hence, total distance by walking 4 times around track :
0.4km * 4 = 1.6km
Additional kilometers Sonya needs to walk:
2.5 - 1.6 = 0.9 km
