Step-by-step explanation:
the works man family car travles 165 miles over 3 hours. Their cousins family car travles 150 miles over 2 hours. If the family reunion is 900 miles away for both familys and asuming both familys continue at the same rate who will arive first? what is the speed of each family?
Thank you so much
Answer:
see answers down below
Step-by-step explanation:
The works man family is driving at a speed of 55 miles per hour
Their cousins family drives at 75 miles and hour. (use the miles/hours ratio like I told you in the last answer)
900 miles/75 miles traveled by their cousins each hour equals 12 hours.
If the works man family is driving at 55 miles and hour, 900 miles needed to be traveled/ 55 miles an hour equals 16.3636363636. This is more than 12 hours, and that means that their cousins will arrive first. Hope this helps!

It is known that x1 and x2 are roots of the equation 3x^2+2x+k=0, where 2x1=−3x2. Find k.
Answer:
k = 8
Step-by-step explanation:
Since the roots of the equation 3x² + 2x + k are x₁ and x₂ and 2x₁ = 3x₂.
By the roots of an equation, ax² + bx + c , where its roots are x₁ and x₂. It follows that sum of roots are x₁ + x₂ = -b/a and product of roots are x₁x₂ = c/a.
Comparing both equations, a = 3 b = 2 and c = k.
So, x₁ + x₂ = -b/a = -2/3 and x₁x₂ = c/a = k/3
x₁ + x₂ = -2/3 and x₁x₂ = k/3
3x₁ + 3x₂ = -2 (1) and 3x₁x₂ = k (2)
Since 2x₁ = -3x₂, and -2x₁ = 3x₂substituting this into equations (1) and (2) above, we have
3x₁ + 3x₂ = -2 (1) and 3x₁x₂ = k (2)
3x₁ + (-2x₁) = -2 and x₁(3x₂) = k
3x₁ - 2x₁ = -2 and x₁(3x₂) = k
x₁ = -2 and x₁(-2x₁) = k
x₁ = -2 and -2x₁² = k
Substituting x₁ = -2 into -2x₁² = k, we have
-2x₁² = k
-2(-2)² = k
2(4) = k
8 = k
So, k = 8
The required value of k is -18
Given the quadratic equation [tex]3x^2+2x+k=0[/tex]
Let the roots of the equation be [tex]x_1 \ and \ x_2[/tex]
From the quadratic equatin:
a = 3, b = 3 and c = k
Sum of root = -b/a
x1 + x2 = -3/3
x1 + x2 = -1 ....................... 1
product of roots = c/a
x1x2 = k/3 ....................... 2
Recall that 2x1=−3x2
x1 = -3x2/2 ........... 3
Substitute equation 3 into 1:
x1 + x2 = -1 ....................... 1
-3x2/2 + x2 = -1
-3x2 + 2x2 = -2
-x2 = -2
x2 = 2
From equation 2:
x1x2 = k/3
2x1 = k/3
-3x2 = k/3
-3(2) = k/3
-6 = k/3
k = -18
Hence the required value of k is -18

Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $8 per hour, Leah cannot
work more than 20 hours per month
How did you determine the pair(s) (x,y) that Leah could work to meet the given conditions in item 157
Answer:
Sorry if I am wrong
Step-by-step explanation:
If you do 5x10 then you would get 50 right then if you also do 8x10 then you would get 80 add those together you get 130. that means if Leah worked 10 hours at Ice cream and 10 hours at babysitting she would not only meet her goal she would have 10 extra dollars.

After four years of college, Erica has to start paying off all her student loans. Her first payment is due at the end of this month. Her bank told her
that she has 10 years to pay off all of her loans, and that starting this month the loans will be compounded monthly at a fixed annual rate of
9.4%.
Erica currently has a total of $29.158.00 in student loans. Using the formula, what is Erica's approximate monthly payment?

The value of Erica's approximate monthly payment is $375.70. The correct option is C .
What is the meaning of Rate of Interest ?Rate of Interest is the rate at which a loan is borrowed or the rate at which an investment gives return .
It is given that
Student Loan Total = $29,158
Rate of Interest = 9.4 %
Time Period = 10 years
The monthly payment is given by
[tex]\rm \dfrac{F p(i) }{ ( 1 - ( 1 + i )^{-n})}[/tex]
Substituting the values in the equation
[tex]\rm = \dfrac{29158* (0.094/12) }{ ( 1 - ( 1 + (0.094/12) )^{-12*10})}[/tex]
= $ 375.70
Therefore,The value of Erica's approximate monthly payment is $375.70. The correct option is C.

Find the values of x and y that satisfy the equation –21 + 5yi = 7x – 10i.
Answer:
The values of x and y are x = -3 and y = -2
Step-by-step explanation:
In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal
a = cb = dLet us use this rule to solve the question
∵ -21 + 5yi = 7x - 10i
∴ The real parts are -21 and 7x
∴ The imaginary parts are 5y and -10
∵ The real parts are equal
∴ 7x = -21
→ Divide both sides by 7
∴ [tex]\frac{7x}{7}[/tex] = [tex]\frac{-21}{7}[/tex]
∴ x = -3
∵ The imaginary parts are equal
∴ 5y = -10
→ Divide both sides by 5
∴ [tex]\frac{5y}{5}[/tex] = [tex]\frac{-10}{5}[/tex]
∴ y = -2
∴ The values of x and y are x = -3 and y = -2

what is the sum of the interior angles of a heptagon ?
Let n be rhe number of vertices in the polygon, then the sum of all interior angle is (n - 2) × 180°.
Number of sides in a heptagon = 7
So, n = 7
So,
the sum of the interior angles of a heptagon
= (7 - 2) × 180°
= 5 × 180°

In circle J with mZHLK = 18, find the mZHJK.
Answer:
The measure of angle HJK is 36°
Step-by-step explanation:
In a circle, the measure of the inscribed angle equal half the measure of the central angle subtended by the same arc
In circle J
∵ J is the center of the circle
∵ H and K lie on the circle
∴ ∠HJK is a central angle subtended by arc HK
∵ L lies on the circle
∴ ∠HLK is an inscribed angle subtended by arc HK
→ By using the rule above
∵ ∠HJK and ∠HLK are the central angle and inscribed angle
subtended by the same arc HK
∴ m∠HLK = [tex]\frac{1}{2}[/tex] m∠HJK
∵ m∠HLK = 18°
∴ 18 = [tex]\frac{1}{2}[/tex] m∠HJK
→ Multiply both sides by 2
∴ 36 = m∠HJK
∴ The measure of angle HJK is 36°
