Solve 6x^2+125=x^2 using square roots.
Answer:
NOREAL SOLUTION
Step-by-step explanation:
6x2+125=x2
Step 1: Subtract x^2 from both sides.
6x2+125−x2=x2−x2
5x2+125=0
Step 2: Subtract 125 from both sides.
5x2+125−125=0−125
5x2=−125
Step 3: Divide both sides by 5.
Step 4: Take square root.

about 56 of every 700 picture frame put togther on an assmbley line have broken pieces of glass if 60,000 picture frames are assembled each month about how many will have broken pieces of glass
9514 1404 393
Answer:
4800
Step-by-step explanation:
Let b represent the number with broken glass. Apparently, the ratio is constant, so ...
b/60000 = 56/700
b = 60000(56/700) = 4800
About 4800 picture frames will have broken glass each month.

It is recommended that one fire extinguisher be available for every 6,000 square feet in a building. Our school
measures 150,000 square feet. Our school has 22 fire extinguishers. The custodian determines that we need more fire extinguishers in order for the entire building to be fully protected.
Answer these two questions and be certain to show and explain all your work.
How many fire extinguishers need to be purchased? What percent of the school is protected now?
Answer:
1 The minimum number of fire extinguishers for Class A hazards for each floor of a building shall be determined by dividing the total floor area by the maximum area to be protected per extinguisher as determined by Table.

A store warehouses 40 more portables than big screen TVs sets and 15 more consoles than big screen sets. Storage cost for the different TVs sets are shown in the table. If storage costs 302 per month how many big screen sets are in stock
Answer:
14 sets
Step-by-step explanation:
Let the number of big screen TV sets be---------x
Portable TV screen sets will be-------x + 40
Console TV sets will be---------- x + 15
The total cost of storage per month is : $302
The equation for total cost is;
7.50 x + 4{ x+15} + 1.50 { x+40 } = 302
7.50x + 4x + 60 + 1.50 x + 60 =302
13x = 302- 120
13x = 182
x = 14

one more than double a number and five more than double a number is 74, what is the number?
Answer:
x = 17
Step-by-step explanation:
Let the number be x.
ATQ,
one more than double a number and five more than double a number is 74,
1+2x+5+2x = 74
We need to find the value of x.
Subtract 6 from both sides,
6+4x-6 = 74-6
4x = 68
x = 17
Hence, the value of x is 17.

Enormous State University's Math Department offers two courses: Finite Math and Applied Calculus. Each section of Finite Math has 60 students, and each section of Applied Calculus has 50 students. The department will offer a total of 110 sections in a semester, and 6,000 students would like to take a math course. How many sections of each course should the department offer in order to fill all sections and accommodate all of the students
Answer:
the department should offer 50 sections of finite math and 60 section of applied calculus in order to fill all sections and accommodate all of the students
Step-by-step explanation:
Given the data in the question'
let x represent number of sections of finite math while y represent number of section of applied calculus.
as 6000 student will like to take math course;
in each section, finite math has 60 students while applied calculus has 50 students
so;
60x + 50y = 6000 --------------lets this be equ 1
we also know that; there are 110 sections in a semester
so;
x + y = 110 ------------------ let this be equ 2
multiply equation 2 by ( - 60 )
-60x + -60y = -6600 --------------- let this be equ 3
now lets add equation 1 and 3
0 - 10y = -600
-10y = -600
divide both sides by (-10)
-10y/-10 = -600/-10
y = 60
now lets substitute value of y in equation 2
x + 60 = 110
x = 110 - 60
x = 50
Therefore, the department should offer 50 sections of finite math and 60 section of applied calculus in order to fill all sections and accommodate all of the students
