Francis earns a weekly salary of $475 plus a 5.5% commission on sales at a girt shop. How much would he earn in a week if he sold $700 in goods? *
Given:
Francis earns a weekly salary of $475 plus a 5.5% commission on sales at a girt shop.
To find:
How much would he earn in a week if he sold $700 in goods?
Solution:
We have,
Fixed weekly salary = $475
Commission percentage = 5.5% on sales.
Total sales of goods = $700
Total commission = 5.5% of 700
[tex]=\dfrac{5.5}{100}\times 700[/tex]
[tex]=5.5\times 7[/tex]
[tex]=38.5[/tex]
Now,
Total weekly salary = Fixed weekly salary + Commission
[tex]=475+38.5[/tex]
[tex]=513.5[/tex]
Therefore, the total weekly salary is $513.5.

given g(x) = x square -7x + 1over4 show that the least possible value of g(x) is -12
Answer:
[tex]-\frac{45}{16}[/tex]
Step-by-step explanation:
[tex]g(x)=\frac{x^{2} -7x+1}{4}[/tex]
Take the derivate of g:
[tex]g'(x)=\frac{x-7}{4}[/tex]
Find x that:
g'(x)=0
solving:[tex]\frac{2x-7}{4}=0\\x=\frac{7}{2}[/tex]
This x give the least possible value that are g(7/2):
[tex]g(\frac{7}{2}) =-\frac{45}{16}[/tex]
Triangle D E F is shown. Angle D E F is 140 degrees. The length of D E is 11, the length of E F is 9, and the length of D F is e.
In ΔDEF, DE = 11, EF = 9, and angle E = 140°.
Which equation correctly uses the law of cosines to solve for the third side?
e2 = 112 + 92 − 2(11)(9)cos(140°)
112 = e2 + 92 − 2e(9)cos(140°)
92 = e2 + 112 − 2e(11)cos(140°)
e = 11 + 9 − 2(11)(9)cos(140°)
Answer:
e2 = 112 + 92 − 2(11)(9)cos(140°)

At the start of the diet keirin weighted 14 stone 13 pounds three months later he weighted 13 stone 10 pounds there are 14 pounds in a stone.
Answer:
The amount of weight he has lost in 3 months is 1.215 stone or 1 stone 3 pounds
Step-by-step explanation:
From the above question, we are to calculate the amount of weight he has lost in three months
1 stone = 14 pounds
Let's convert all the weight lost to stone
At the start of the diet keirin weighted 14 stone 13 pounds
14 pounds = 1 stone
13 pounds = x
Cross Multiply
14x = 13
x = 13/14
x = 0.9285714286 stone
Approximately = 0.929 stone
Hence:
14 stone 13 pounds = 14 + 0.929 = 14.929 stone
Three months later he weighted 13 stone 10 pounds
14 pounds = 1 stone
10pounds = x
Cross Multiply
14x = 10
x = 10/14
x = 0.7142857143 stone
Approximately = 0.714 stone
Hence:
13 stone 10 pounds = 13 + 0.714 = 13.714 stone
The amount of weight he has lost is calculated as:
14.929 stone - 13.714 stone = 1.215 stone or 1 stone 3 pounds

In triangle WXY, the measure of angle Y=90 degrees, XW=89, WY=80, and YX=39. What ratio represents the cosine of angle X?
Answer: [tex]\dfrac{39}{89}[/tex]
Step-by-step explanation:
Given: In triangle WXY,
∠Y = 90°, XW = 89 units, WY = 80 units and YX = 39 units.
According to trigonometry ,
Cosine of A [tex]=\dfrac{\text{side adjacent to A}}{\text{hypotenuse}}[/tex]
From the figure below,
[tex]\text{cosine of } \angle X=\dfrac{YX}{WX}\\\\=\dfrac{39}{89}[/tex]
Hence, required ratio = [tex]\dfrac{39}{89}[/tex]

A company sells floats for children. An equation that models their profit is P=4x-10,000 , where x is the number of floats sold.
If 5,000 floats are sold, what is the company's profit?
Answer:
P = $10,000
Step-by-step explanation:
The equation modeling a company's profit is P = 4x - 10000.
Substitute x for 5,000.
P = 4(5,000) - 10,000
P = 20,000 - 10,000
P = 10,000
The company's profit will be $10,000 if 5,000 floats are sold.

Answer:
The correct graph is the first graph on the top left corner amongst the options
Step-by-step explanation:
The graph that shows that Cindy reads about 3/4 of the time while riding the car is given by the following relation;
Let 't' represent the time Cindy spend riding the car
Therefore, we are given that
The time Cindy spend reading = 3/4·t
Therefore, when Cindy rides the car for t = 4 hours, the time Cindy spend reading = 3/4·t = 3/4 × 4 = 3 hours
The coordinates of the point on the graph will therefore, be (4, 3)
Therefore, when the y-coordinate of the graph )the time Cindy spends reading) = 3, the x-coordinate of the graph (the time Cindy spends driving) = 4
Please find, the correct graph attached here, created with Microsoft Excel which is equivalent to the first graph on the top left corner amongst the options

The difference of two complementary angles is 70 degrees. Find the measures of the angles.
Answer:
[tex]80[/tex]° and [tex]10[/tex]°
Step-by-step explanation:
Complementary angles are a pair of angles whose measures have a sum of [tex]90[/tex]°. Therefore, if we let the measure of the bigger angle be [tex]x[/tex], then the measure of the smaller angle will be [tex]x-70[/tex] because we are given that the difference of the measures of the two angles is [tex]70[/tex]°. We can write the following equation to solve for [tex]x[/tex]:
[tex]x+x-70=90[/tex]
Solving for [tex]x[/tex], we get:
[tex]x+x-70=90[/tex]
[tex]2x-70=90[/tex] (Simplify LHS)
[tex]2x-70+70=90+70[/tex] (Add [tex]70[/tex] to both sides of the equation to isolate [tex]x[/tex])
[tex]2x=160[/tex] (Simplify)
[tex]\frac{2x}{2}=\frac{160}{2}[/tex] (Divide both sides of the equation by [tex]2[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=80[/tex] (Simplify)
Therefore, the measure of one angle is [tex]80[/tex]° and the measure of the other angle is [tex]x-70=80-70=10[/tex]°. Hope this helps!
We know, sum of complementary angles = 90°
Let, one of the angle = x°
∴ Another angle = (90 - x)°
As per condition,
(x°) - (90 - x)° = 70°
⇒ x° - 90° + x° = 70°
⇒ 2x° = 70° + 90° = 160°
⇒ x° = 80°.
So, angles are:-
x° = 80° (90 - x)° = (90 - 80)° = 10°.PLZ HELP !!!! WILL MARK BRAINLIEST, THIS IS DUE IN 15 MINUTIES !!!ANYONE PLEASE

A right-angled triangle has sides of lengths (x+5)cm, (x-3)cm and 9cm. Calculate the value of x
Answer:
x=4.0625 cm
Step-by-step explanation:
The Pythagorean theorem states that the square of the hypotenuse of a right triangle equals the sum of the squares of the two legs.
Not knowing which is the hypotenuse, lets assume that (x+5)cm is the hypotenuse:
(x+5)^2= 9^2+(x-3)^2
(x^2+10x+25)=81+(x^2-6x+9)
x^2+10x+25=81+x^2-6x+9
16x=65
x=4.0625
Checking:
(4.0625+5)^2=9^2+(4.0625-3)^2
82.1289=82.1289
Answer:
x = (3.95 and -5.95)
Step-by-step explanation:
Given:
Hypotenuse = 9 cm
Perpendicular = (x+5) cm
Base = (x-3) cm
Find:
Value of x
Computation:
Using Pythagoras theorem
Hypotenuse² = Perpendicular² + Base²
9² = (x+5)² + (x-3)²
81 = x² + 25 + 10x + x² + 9 - 6x
2x² + 4x - 47 = 0
Quadratic Formula
x = [-b±√b²-4ac] / 2a
x = [-4±√16+376] / 2(2)
x = (3.95 and -5.95)
A boy is twice as tall as his little sister and 30cm shorter than his father. Their combined height is 3.8 meters. Find (in cm) the height of each person.
Answer:
Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation
x + 2x + 2x + 30 = 380
collect like terms
5x = 350
x = 70
the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm
Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct

Factorise (x + y)^2 + 3(x + y)
=(x+y) [(x+y) +3]
=(x+y) (x+y+3)
(x + y) (x + y+3) is the factorized form of (x + y)² + 3(x + y)
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given equation is (x + y)² + 3(x + y)
We know that (a + b)²=a²+b²+2ab
Similarly (x + y)²=x²+y²+2xy
Substitute this in above equation
x²+y²+2xy+3(x + y)
x²+y²+2xy+3x+3y
Factorising it we get
(x + y) (x + y+3)
Hence, (x + y) (x + y+3) is the factorized form of (x + y)² + 3(x + y)
