Answer:
Yes, it can.
Step-by-step explanation:
Looking at this table, we can see that each type of hat is ALWAYS next to the same type of flower.
Berets are ALWAYS next to Daffodils.
Panamas are ALWAYS next to Sunflowers.
Cloches are ALWAYS next to Violets.
Bowlers are ALWAYS next to Irises.
Fedoras are ALWAYS next to Narcissuses.
If we assume that every type of FLOWER is a number and every type of HAT is also a number, these will all match up.
So, they are consistent.
This means that the type of flower can be represented as a function of the type of hat.

Karina uses the system of equations below to compare the monthly utility costs in July and December for electricity, x, and natural gas, y. 750x + 17y = 141.61 300x + 30y = 75.90 Karina solves the system using linear combination and arrives at the equation 116y = 96.28. She then solves this equation for y. Which statement explains Karina’s solution?
Answers
Answer:
d. The cost of natural gas (y) = $0.83 per unit
Step-by-step explanation:
The explanation is shown below:-
the equation of system is:
750x + 17y = 141.61 (i)
300x + 30y =75.90 (ii)
as x indicates the cost of electricity and y indicates the costs of natural gas.
we will solve the both equation with the help of multiplication for (i) by 30 and for (ii) 75
[tex]30\times (750x + 17y) 30\times 141.61\\\\[/tex]
after solve the above equation we will get
22,500x + 510y = 4248.3 (iii)
[tex]75\times (330x + 30y) = 75\times 75.90[/tex]
after solve the above equation we will get
22500x + 2250y = 5692.5 (iv)
After deducting the equation (iii) and (iv) we will get
1740 y = 1444.2
After Dividing by 15 both sides,
116y = 96.28
So, Katrina simplify the above system using linear equation and reach at the equation that is
116 y = 96.28
By Division property of equality defines that divide the equal no. of both sides of an equation:
by Division of 116 to both sides of an equation, to get y:
[tex]\frac{116y}{116} = \frac{96.28}{116}[/tex]
y = 0.83
So, the natural gas is $0.83 per unit

Step-by-step explanation:
Let sin(−θ)=−35 and tanθ>0. What is the value of cos(−θ)?
Answers
Answer:
cos(−θ) = -4/5
Step-by-step explanation:
The correct question is as follows;
Let sin(−θ)=−3/5 and tanθ>0. What is the value of cos(−θ)?
Solution as follows
Here in this question, we have that tanθ>0. what this means is that tan is positive here.
Now what do we notice about the value of the sin? For the negative angle to give a negative sin value, what this means is that the value of sin at the particular quadrant is positive, hence we can also conclude that sinθ>0
Now which quadrant do we have both sine and tangent positive? That is only the first quadrant.
Coincidentally, the value of cos here too is positive.
Since we are dealing with the first quadrant, we only need to find the value of theta.
Mathematically;
Sine theta = opposite/hypotenuse
Now ;
Cos theta = adjacent/hypotenuse
So therefore, to find the value of the adjacent , we need to employ the use of Pythagoras’ theorem
Mathematically, the square of the hypotenuse equals the sum of the squares of the adjacent and opposite
According to the values in this question
Adjacent = √(5)^2 -(3^2)
Adjacent = √(16) = 4
Thus ;
cos(−θ) = -4/5

Answers
Answer:
0Step-by-step explanation:
Given the expression after 4 has been subtracted from both sides as
1/2 x = - 1/2 x, the original expression will be gotten by adding back 4 to both sides of the resulting expression as shown;
1/2 x + 4 = - 1/2 x + 4
x/2 + 4 = -x/2 + 4
Find the LCM of both equation;
(x+8)/2 = (-x+8)/2
Multiplying both sides by 2 will give;
x+8 = -x+8
Collecting the like terms;
x+x = 8-8
2x = 0
x = 0/2
x = 0
Hence, the value of x is 0

Answers
Answer:
1kg of salami cost $9.1
Step-by-step explanation:
Hailey paid $13 for 1 3/7 kg of sliced salami.
What was the cost per kilogram of salami?
Cost of 1 3/7 kg of sliced salami=$13
1 3/7 kg=10/7kg
Let x=1 kg of sliced salami
10/7 kg of x=$13
$13=10/7x
13=10/7*x
x=13 ÷ 10/7
=13×7/10
=91/10
=9.1
x=$9.1
Therefore, 1kg of salami cost $9.1
In isosceles triangle the length of the base is twice shorter than the length of a leg. The perimeter of this triangle is 50 cm. Find the lengths of all sides.
Answers
Answer:
The base is 10cm. The other two sides are 20cm each
Step-by-step explanation:
I believe that "the base is twice shorter" means that the two equal sides of the iscosceles triangle are twice the length of the base.
Using the equation x + 2x +2x = 50 where x is the length of the base, we can simplify it to
5x=50. Then divide both sides by 5 to get the results:
x=10 for the base and
2x=20 for the other two sides.

In a school, 25% of the teachers teach basic math. If there are 50 basic math teachers, how many teachers are there in a school?
Answers
Answer:
200 teachers
Step-by-step explanation:
If 25% is a fourth of the teacher staff, and this value is fifty, to find out how many teachers there are you just have to multiply by 4 to find out the 100%. So this means that 50*4= 200
Answer:
Total teachers = 200
Step-by-step explanation:
Let x be the total teachers in school
Basic Maths teachers = 25 % of x
Basic Maths Teachers = 50
=> 25% of x = 50
=> [tex]\frac{25}{100} x = 50[/tex]
=> [tex]\frac{x}{4} = 50[/tex]

Answers
Answer:
25
Step-by-step explanation:
let his age be x, then
5 years ago his age was x - 5 and in 5 years will be x + 5 , thus
(x - 5)(x + 5) = 600 ← expand factors using FOIL
x² - 25 = 600 ( add 25 to both sides )
x² = 625 ( take the square root of both sides )
x = [tex]\sqrt{625}[/tex] = 25
Answer:
[tex]\boxed{Age \ of \ man = 25 \ years}[/tex]
Step-by-step explanation:
Let the age be x
Then, the given condition is:
(x-5)(x+5) = 600 [ x-5 for age 5 years ago and x+5 for age 5 years after ]
Using Formula [tex](a+b)(a-b) = a^2-b^2[/tex]
[tex]x^2-25 = 600[/tex]
Adding 25 to both sides
[tex]x^2 = 600+25[/tex]
[tex]x^2 = 625[/tex]
Taking sqrt on both sides

6 agents can sell 333 cars in 3 months.
=> 6 agents can sell 333/3 cars in 3/3 month.
=> 6 agents can sell 111 cars in 1 month.
Fixing number of months:
=> 6/2 agents can sell 111/2 cars in 1 month.
=> 3 agents can sell 111/2 cars in 1 month.
Then considering that 3 agents worked in 6 months:
=> 3 agents can sell 6 x 111/2 cars in 6 x 1 months.
=> 3 agents can sell 333 cars in 6 months.

The domain of the function is all values of x except where the function does not exist
This is where the denominator goes to zero
(x-4) ( x-2) =0
Using the zero product property
x-4 =0 x-2 =0
x=4 x=2
The domain is all values but x=4 and x=2

Answer:
The function has two real roots and crosses the x-axis in two places.
The solutions of the given function are
x = (-0.4495, 4.4495)
Step-by-step explanation:
The given quadratic equation is
[tex]G(x) = -x^2 + 4x + 2[/tex]
A quadratic equation has always 2 solutions (roots) but the nature of solutions might be different depending upon the equation.
Recall that the general form of a quadratic equation is given by
[tex]a^2 + bx + c[/tex]
Comparing the general form with the given quadratic equation, we get
[tex]a = -1 \\\\b = 4\\\\c = 2[/tex]
The nature of the solutions can be found using
If [tex]b^2- 4ac = 0[/tex] then we get two real and equal solutions
If [tex]b^2- 4ac > 0[/tex] then we get two real and different solutions
If [tex]b^2- 4ac < 0[/tex] then we get two imaginary solutions
For the given case,
[tex]b^2- 4ac \\\\(4)^2- 4(-1)(2) \\\\16 - (-8) \\\\16 + 8 \\\\24 \\\\[/tex]
Since 24 > 0
we got two real and different solutions which means that the function crosses the x-axis at two different places.
Therefore, the correct option is the last one.
The function has two real roots and crosses the x-axis in two places.
The solutions (roots) of the equation may be found by using the quadratic formula
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
[tex]x=\frac{-(4)\pm\sqrt{(4)^2-4(-1)(2)}}{2(-1)} \\\\x=\frac{-4\pm\sqrt{(16 - (-8)}}{-2} \\\\x=\frac{-4\pm\sqrt{(24}}{-2} \\\\x=\frac{-4\pm 4.899}{-2} \\\\x=\frac{-4 + 4.899}{-2} \: and \: x=\frac{-4 - 4.899}{-2}\\\\x= -0.4495 \: and \: x = 4.4495 \\\\[/tex]
Therefore, the solutions of the given function are
x = (-0.4495, 4.4495)
A graph of the given function is also attached where you can see that the function crosses the x-axis at these two points.

Answers
Answer:
Misty is the more consistent employee
Step-by-step explanation:
The given data are
Misty: 11, 13, 12, 14, 10, 16, 14
Brock: 8, 15, 10, 11, 16, 10, 9
The mean of Misty's successfully answered questions = ∑x/n = 90/7 = 12.86
Misty's data standard deviation = √(∑(x - μ)²/n) = 1.884
The mean of Brock's successfully answered questions = ∑x/n = 79/7 = 11.29
Brock's data standard deviation = √(∑(x - μ)²/n) = 2.81
Therefore, based on the value of the standard deviation which is a measure of variability, whereby the standard deviation of Brock's number of successfully answered questions is larger than the standard deviation of Misty's number of tech supported successfully answered questions, Misty is the more consistent employee.
