Answer:
Firas = $320
Nabil = $80
Step-by-step explanation:
Firas = 4x
Nabil = x
x + 240 = 4x
3x = 240
x = $80
Firas = $240 + $80 OR $80 x 3 = $320
Nabil = $80

Sin θ = ____ csc θ = ____ cos θ = ____ sec θ = ____ tan θ = ____ cot θ = ____ Equation of the Circle: _ the unit circle (r = 1), find the value of the six trig ratios:
Answer:
a. Sin θ = y/r
b. csc θ = r/y
c. cos θ = x/r
d. sec θ = r/x
e. tan θ = y/x
f. cot θ = x/y
g. x² + y² = 1
Step-by-step explanation:
Where (x, y) are the x and y coordinates of the position with radius r and angle θ measured from the positive x axis. y is the opposite side to the angle θ and x is the adjacent side to the angle θ and r is the hypotenuse side of the right-angled triangle formed by x, y and r. Also, x² + y² = r²
a. Sin θ = opposite/hypotenuse = y/r
b. csc θ = hyotenuse/opposite = 1/Sin θ = r/y
c. cos θ = adjacent/hypotenuse = x/r
d. sec θ = hypotenuse/adjacent = 1/cos θ = r/x
e. tan θ = opposite/adjacent = y/x
f. cot θ = adjacent/opposite = 1/tan θ = x/y
g. Equation of the Circle: _ the unit circle (r = 1),
Since x² + y² = r² ,for a unit circle, r = 1. So,
x² + y² = 1²
x² + y² = 1
Under his cell phone plan, Parker pays a flat cost of $47.50 per month and $3 per gigabyte, or part of a gigabyte. (For example, if he used 2.3 gigabytes, he would have to pay for 3 whole gigabytes.) He wants to keep his bill under $60 per month. What is the maximum whole number of gigabytes of data he can use while staying within his budget?
Answer:
Its 4 but ima just explain it :- )
Step-by-step explanation:
okay so what you gotta do is 60 - 47.50=12.5/3=4.166666
4.1666 you turn into 4
Maximum possible number of gigabytes 47.50+ 3x ≤ 60
The number of maximum gigabytes of data he can use would be 4.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions. It shows a relationship between two numbers or two expressions.
We have,Cost of flat per month = $47.50
Cost per gigabyte = $3
Maximum bill per month = $60
Maximum possible number of gigabytes as;
47.50 + 3x ≤ 60
Where x is the number of gigabytes.
Solve for x;
47.50 + 3x ≤ 60
3x ≤ 60 - 47.50
3x ≤ 12.5
x ≤ 47.50/3
x ≤ 4.1
x ≤ 4
This means that the number of maximum gigabytes of data he can use is 4.
We can cross-check.
47.50 + 3 x 5 ≤ 60
47.50 + 15 ≤ 60
61 ≤ 60 ( not possible )
So,
47.50+ 3 x 4 ≤ 60
47.50 + 12 ≤ 60
58 ≤ 60
Thus,
The number of maximum gigabytes of data he can use is; 4.

Colin buys a tv for £800. It depreciates at a rate of 4% per year. How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate
Answer:
£707.8
Step-by-step explanation:
Given data
Price= £800
Rate= 4%
Time= 3 years
Let us apply the compounding formula
A=P(1-r)^r-------------Note the negative sign is because of depreciation
substitute
A= 800(1-0.04)^3
A= 800(0.96)^3
A=800*0.884736
A= £707.8
Hence the value will be £707.8

Brianna has $37 in her checking account. She deposits $150. Then she writes a check for $61. How many dollars does she have in her checking account now?
Answer:
$126
Step-by-step explanation:
A deposit adds money into your checking account, so add $150 to $37.
150+37=187
If you write a check, you take money out, so subtract $61 from $187
187-61=126
Your final answer is $126. Hope this helps!

Traveon is walking dogs for his neighbors, to make money. This week, he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog. If the total distance that he walked both dogs is 17.5 miles, how far did he walk Ms. Evans' dog? *
Answer:
He walked Ms. Evans' dog 3.89 miles.
Step-by-step explanation:
From the information provided, you know that the total distance that he walked both dogs is 17.5 miles, which can be expressed as:
x+y=17.5, where:
x is the distance he walked Mr. Jackson's dog
y is the distance he walked Ms. Evans' dog
Also, the statement indicates that he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog and you can write the following equation:
x=3.5y
Now, you can replace x=3.5y in the first formula and solve for y to find how far he walked Ms. Evans' dog:
3.5y+y=17.5
4.5y=17.5
y=17.5/4.5
y=3.89
According to this, the answer is that he walked Ms. Evans' dog 3.89 miles.

P(x) =0.02x³+0.04x²+0.3x+1.2.Evaluate P(18) by direct substitution and by applying the remainder theorm
Answer:
136.2
Step-by-step explanation:
Plugin x = 18 in the polynomial.
P(x) = 0.02x³ + 0.04x² + 0.3x + 1.2
P(18)= 0.02*(18)³ + 0.04*(18)² + 0.3*18 + 1.2
= 0.02 * 5832 + 0.04*324 + 5.4 + 1.2
= 116.64 + 12.96 + 5.4 + 1.2
= 136.2

1.y-2=3(x-3)
y-2=3x-9
y=3x-9+2
y=3x-7
2.y-(-2)=-3(x-(-1))
y+2=-3x-3
y=-3x-3-2
y=-3x-5
3.y-1=1(x-(-1)
y-1=1(x+1)
y-1=1x+1
y=1x+1+1
y=1x+2
4,y-(-3)=-4(x-1)
y+3=-4x+4
y=-4x+4-3
y=-4x+1
5.y-2=1(x-(-4)
y-2=1(x+4)
y-2=1x+4
y=1x+4+2
y=1x+6
6.y-3=1/2(x-(-4)
y-3=1/2(x+4)
y-3=1/2x+4/2 simplify 4/2 to 2/1 =2
y=1/2x+2+3
y=1/2x+5

Step-by-step explanation:
Two students, Jennifer and Jamal, factored the trinomial 4x2 − 6x − 4. Jennifer factored it as 2(x − 2)(2x + 1) and Jamal factored it as (x − 2)(4x + 2). Indicate which student factored the trinomial completely and which student did not, and explain why
Jennifer factored it completely because she pulled out the common factor of the three terms, which 2.
This simplifies the trinomial to 2(2x^2-3x-2) and then this factors to be 2(x − 2)(2x + 1)

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
12. In a certain cafe, all the sandwiches and drinks are priced the
same. A customer ordered three sandwiches and two drinks for
$14.70. Another customer bought two sandwiches and four drinks
for $13.80. Find the cost of one sandwich and the cost of one drink.
The cost of one sandwich is $3.90
The cost of one deknk is $1.50
hopefully this is correct
The system of equations are
The cost of one sandwich x = $ 3.90
The cost of one drink y = $ 1.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of one sandwich be x
Let the cost of one drink be y
Now , the equation will be
A customer ordered three sandwiches and two drinks for $14.70
So , 3x + 2y = 14.70 be equation (1)
And , Another customer bought two sandwiches and four drinks for $13.80
So , 2x + 4y = 13.80 be equation (2)
On simplifying the equations , we get
Multiply equation (1) by 2 , we get
6x + 8y = 29.4 be equation (3)
Subtracting equation (2) from equation (3) , we get
4x = 15.6
Divide by 4 on both sides of the equation , we get
x = $ 3.90
So , the cost of one sandwich is $ 3.90
And ,
Substituting the value of x in equation (1) , we get
3x + 2y = 14.70
3 ( 3.90 ) + 2y = 14.70
11.70 + 2y = 14.70
Subtracting 11.70 on both sides of the equation , we get
2y = 3
Divide by 2 on both sides of the equation , we get
y = $ 1.50
So , the cost of one drink is $ 1.50
Hence , the cost of one sandwich and one drink is $ 3.90 and $ 1.50 respectively
