Answer:
They must sell 2700 dollars to recieve the same sallary.
Step-by-step explanation:
The expression for Scarlett's sallary is:
g(x) = 185 + 0.03*x
The expression for Mia's sallary is:
f(x) = 23 + 0.09*x
In order for them to recieve the same sallary they must sell:
185 + 0.03*x = 23 + 0.09*x
0.09*x - 0.03*x = 185 - 23
0.06*x = 162
x = 162/0.06 = 2700
They must sell 2700 dollars to recieve the same sallary.

2. 2x - y = 6,
- x + y = -1
Answer:
x = 5
y = 4
Step-by-step explanation:
just substitute the value of one variable into the other
-x +y = -1
or y = -1 +x <-------- (i just added x to the right side)
now u know what y is equal to, just substitute that value into the first equation
2x - (-1+x) = 6 <-------- instead of y, i put the value of y from the 2 equation
NOW SOLVE FOR X!
2x +1 -x = 6
x + 1 = 6
x = 5
now solve for y since you have the value of x
y = -1 + x
or y = -1 + 5
y = 4
Answer:
y=3.166 x=4.166

Question 28
Let be an angle in quadrant such that.
Find the exact values of and.
Answer:
see explanation
Step-by-step explanation:
Since Θ is an angle in the third quadrant, then secΘ < 0 and tanΘ > 0
Using the identity
sec x = [tex]\frac{1}{cosx}[/tex] , then
cos x = - [tex]\sqrt{1-sin^2x}[/tex]
= - [tex]\sqrt{1-(-3/5)^2}[/tex] = - [tex]\sqrt{1-\frac{9}{25} }[/tex] = - [tex]\sqrt{\frac{16}{25} }[/tex] = - [tex]\frac{4}{5}[/tex], thus
secΘ = [tex]\frac{1}{-\frac{4}{5} }[/tex] = - [tex]\frac{5}{4}[/tex]
---------------------------
Using the identity
tan x = [tex]\frac{sinx}{cosx}[/tex] , then
tanΘ = [tex]\frac{-\frac{3}{5} }{-\frac{4}{5} }[/tex] = - [tex]\frac{3}{5}[/tex] × - [tex]\frac{5}{4}[/tex] = [tex]\frac{3}{4}[/tex]
The value of sec(x) is (5/4) and tan(x) will be (-3)(4).
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
Sine, cosine, tangent, cosecant, secant, and cotangent are some of their names. The adjacent side, opposite side, and hypotenuse side of the right triangle are used to define each of these trigonometric ratios.
The six trigonometric ratios are the source of all fundamental trigonometric identities.
The given value of sin (x) is ( -3 / 5 ). The values of sec(x) and tan(x) will be calculated as below:-
sec(x) = 1 / cos(x)
[tex]cosx = \sqrt{1-sin^2x}[/tex]
[tex]cosx = \sqrt{1-(\dfrac{-3}{5})^2}[/tex]
cos(x) = 4 / 5
sec(x) = 1 / ( 4 / 5 ) = ( 5/ 4)
The value of tan(x) will be calculated as:-
tan(x) = sin(x)/cos(x) = ( -3 / 5 ) / (4 / 5 )
tan(x) = (-3/4)
Therefore, the value of sec(x) is (5/4) and tan(x) will be (-3)(4).

A boat is anchored 2.2 km due south of a lighthouse. Along the shore, the town of Beachton is 16.8 km due east of the lighthouse. Enter a number in the box to correctly complete the statement. Round the answer to the nearest tenth. The distance from the boat to Beachton is 16 point 9 km
Answer:
16.9 km
Step-by-step explanation:
From the diagram attached, we can see that the problem forms a triangle.
So, to find the distance(d) from the boat to Beachton , we can make use of Pythagoreas theorem.
Thus;
d² = 16.8² + 2.2²
d² = 282.24 + 4.84
d² = 287.08
d = √287.08
d = 16.9434
Approximating to the nearest tenth, we have;
d ≈ 16.9 km

Answer:
the value of x is 5 .
Step-by-step explanation:
In order to find the value of x, you have to move the unrelated terms to the other side by adding 4 to both sides :
[tex]11 = 3x - 4[/tex]
[tex]11 + 4 = 3x - 4 + 4[/tex]

Habib is making some scones.
His recipe tells him to bake the scones at 356°F for 30 minutes.
The temperature gauge on Habib's oven shows the temperature in
degrees Celsius, "C.
The formula to convert °F (Fahrenheit) into °C is:
C = 5F - 160
At what temperature, in °C, should Habib bake his scones?
Answer:
1620°C
Step-by-step explanation:
Using the equation
C = 5F - 160, at 356°F we'll have
C = 5(356) - 160
C = 1780 - 160
C = 1620°C

It should be noted that it is defined as zero if the line is horizontal, but undefined if it is vertical.
Given:
Coordinates (- 3, 7) (2, - 6)
y1 = 7, y2= -6, x1= -3, x2=2
Slope : ∆ y/ ∆ x
= (y2 - y1 )/ (x2 - x1)

Answer:A
Step-by-step explanation:
A box-and-whisker plot. The number line goes from 0 to 25. The whiskers range from 2 to 15, and the box ranges from 3 to 8. A line divides the box at 6. Option A is correct.
What is a box plot?A straightforward method of expressing statistical data on a plot in which a rectangle is drawn to represent the second and third quartiles, with a vertical line inside to indicate the median value. Horizontal lines on both sides of the rectangle show the lower and upper quartiles.
Here,
The lower quartile (Q1) of the data set is 3, so the bottom of the box must start at 3.
The interquartile range (IQR) is 5, so the upper quartile (Q3) must be
Q1 + IQR = 3 + 5 = 8
The median (also called the first quartile) is halfway between Q1 and Q3, so it must be at (Q1 + Q3) / 2 = (3 + 8) / 2 = 6.
The whiskers extend to the minimum and maximum values within 1.5 * IQR of the box, so they must range from 2 to 15.

Stir-fry is Vince's favorite food to cook, but it always makes a lot of smoke! Vince needs to know the volume of his kitchen so he can buy a fan that is the right size. Vince's kitchen has a floor area of 85 square feet. The height of the ceiling is 8 feet. What is the volume of Vince's kitchen?
Answer:
The volume of Vince’s Kitchen is 680 cubic feet
Step-by-step explanation:
To calculate the volume of Vince’s kitchen, what is needed to be done is to multiply the area of the floor by the height of the kitchen
Mathematically Volume V of kitchen = area of kitchen floor * height of kitchen
From the question, the area of the kitchen floor = 85 square feet
Height of kitchen = 8 feet
Plugging these values to get the area of the Kitchen, we have;
V = 8 * 85 = 680 cubic feet

Parallelogram efgh has sides of length 20 inches and 14 inches as shown. Its acute angle measures 62 degrees. Find the area of efgh to the nearest square inch
Answer:
The area of the parallelogram is 247 inches^2 to the nearest square inch
Step-by-step explanation:
This question asks us to calculate the area of a parallelogram given the sides and an acute angle.
Please check attachment for diagrammatic representation of the said parallelogram.
Mathematically, the area of the parallelogram can be calculated using the formula;
A = ab sin θ
where a and b refers to the length of the two sides and θ being the acute angle
Substituting these values, we have
A = 20 * 14 * sin 62
A = 280 sin 62 = 247.23 which is 247 inches^2 to the nearest square inch
