Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. Find her total profit.
Answer:
$108
Step-by-step explanation:
The computation of the total profit is shown below:
Given that
1 box = $12
18 boxes = 12×18 = $216
So
Total = 18×65 = 1170 pens
Now Cost price, Cp = $216
Also,
3 = $1
So,
= 378 ÷ 3
= $126
Now
= 1170-378
= 792 pens remaining
4 = $1
So,
792
= 792 ÷ 4
= $198
Now
Total selling price, sp = 126+198 = $324
So finally
Profit = Sp - Cp
= $324 - $216
= $108

Complete the equation of the line through (-6, 5) and (-3, -3)
Answer:
y = -8/3x - 11
Step-by-step explanation:
(-6, 5) and (-3, -3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-5)/(-3+6)
m=(-8)/3
m= -8/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -8/3(x + 6)
y - 5 = -8/3x - 16
y = -8/3x - 11

You are a laboratory technician. You are filling spherical flasks with a salt solution and then putting them into boxes. Each flask has a volume of 113.04 cubic inches.
Rounded to the nearest tenth of an inch, what is the radius of one flask?
3.0
3.6
5.2
6.4
6.9
Answer:
3.0 inches
Step-by-step explanation:
The formula for the volume of a sphere is
V = 4/3 × π × r³
V = 113.04 cubic inches
To find r
r = (3V/4π)⅓
r = (3 × 113.04/4 × π )⅓
r = 3.0 inches
The radius of one flask = 3.0 inches

A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344
A soccer player is 30 feet from the goal line. He shoots the ball directly at the goal.
The goal is 8 feet high. What is the maximum angle of elevation at which the player
can shoot the ball and still score a goal?
Answer:
14.93°
Step-by-step explanation:
Using trigonometry :
From the diagram attached :
Angle of elevation = x
To obtain the value of x
Tan x = opposite / Adjacent
Tan x = 8 / 30
Tan x = 0.266666
x = tan^-1(0.26666)
x = 14.93°
Therefore, the angle of elevation is 14.93°

find NM
Answer:
NM = 15
Step-by-step explanation:
Given a secant and a tangent from an external point to the circle, then
The square of the measure of the tangent is equal to the product of the secant's external part and the entire secant, that is
(x + 3)² = (x - 3)(x - 3 + 16)
(x + 3)² = (x - 3)(x + 13) ← expand both sides using FOIL
x² + 6x + 9 = x² + 10x - 39 ( subtract x² + 10x from both sides )
- 4x + 9 = - 39 ( subtract 9 from both sides )
- 4x = - 48 ( divide both sides by - 4 )
x = 12
Then
NM = x + 3 = 12 + 3 = 15

Answer:
22
Step-by-step explanation:
Hey There!
So if you didn't know angle H is a right angle. So we are given two angles and they want us to find the missing angle
Remember all of the angles of a triangle add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-90-68=22
so we can conclude that angle G = 22

Answer:
x₂ = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{5}{6}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 9) and (x₂, y₂ ) = (x₂, - 1)
m = [tex]\frac{-1-9}{x_{2}-9 }[/tex] , that is
[tex]\frac{-10}{x_{2}-9 }[/tex] = [tex]\frac{5}{6}[/tex] ( cross- multiply )
5(x₂ - 9) = - 60 ( divide both sides by 5 )
x₂ - 9 = - 12 ( add 9 to both sides )
x₂ = - 3
evaluate each function in the table for f(3)
Answer:
Function 1:
We have 3x + 5, so we plug in 3 for x to get 9 + 5 = [tex]\boxed{14}[/tex]
Function 2:
We have [tex]\frac{1}{2}x^{2} - 1.5[/tex] so we have 4.5 - 1.5 = [tex]\boxed{3}[/tex]
Function 3:
We have [tex]\frac{3}{2x}[/tex] which becomes [tex]\frac{3}{6} = \boxed{\frac{1}{2}}[/tex].

Find the surface area of the cube show below
2/3
Answer:
Step-by-step explanation:
there are 6 sides on a cube
surface area = 6 times the area of one face of the cube
= 6 times ( a side times another side) note all sides are equal
= 6(side)² is a side equal to 2/3 ?? if it is ....
= 6(2/3)²
= 6(2/3)(2/3) one of the 3s divide into 6 twice
= 2(2)(2/3)
= 2³ / 3
= 2x2x2 / 3
= 8 /3
= 2 and 2/3 units²

what is the answer for 9k^2=225
9k² = 225
k² = 225 : 9
k² = 25
k = -5 and k = 5 because :
(-5)² = (-5) * (-5) = 25
5² = 5 * 5 = 25
Ms. Etienne deposited $450 into an account that paid 5% interest compounded annually. She did not make any
additional deposits or withdrawals.
Which amount is closest to the value of the account at the end of 6 years?
A $603.04
B $585.00
© $463.67
o
$463.50
Answer:
$603.04
Step-by-step explanation:
The Compound Amout formula is A = P(1 + r)^t, where:
P is the principal (initial deposit), r is the annual interest rate as a decimal fraction, and t is the time period in years.
In this particular case, the Compound Amount is:
A = ($450)(1 + 0. 05)^6 = ($450)(1.34) = $603.04

62\100
simplest form
45\100
simplest form
Answer:
62/100= 31/50
45/100= 9/20
Step-by-step explanation:
Divide 62 and 100 by two to simplify
Divide 45 and 100 by 5 to simplify
Answer:
62/100 = 31/50
45/100 = 9/20
Step-by-step explanation:
62 and 100 have a greatest common factor of 2. We can use this to break the fraction 62/100 apart:
[tex]\dfrac{62}{100}=\dfrac{2\times31}{2\times50}=\dfrac{2}{2}\times\dfrac{31}{50}=\dfrac{31}{50}[/tex]
We can do the same to simplify 45/100. The greatest common factor of 45 and 100 is 5, so following the same process:
[tex]\dfrac{45}{100}=\dfrac{5\times9}{5\times20}=\dfrac{5}{5}\times\dfrac{9}{20}=\dfrac{9}{20}[/tex]
