Answer:

52%

Step-by-step explanation:

you got to divide 15 by 785. First 15 goes into 78 5 times which is 75. Then subtract 78 by 75 which is 3. Then bring down the 5 which makes 35 and then 15 goes into 35 two times which is 30 subtract 35 by 30 which is 5 bring up the 5 into a fraction and the ansewer in percentage is  52%.

Answer: -7, 12

Step-by-step explanation:

a+b = 5

a*b = -84

a = 5-b

(5-b)*b = -84

-b^2 + 5b + 84 = 0

(-b - 7)(b + 12) = 0

The roots are -7 and 12.

68+37 = 105  

$105 dollars for an 8 hour shift

$68 salary + $37 tips = $105

Answer:

total wage in 8 hrs = $105  

Step-by-step explanation:

37 + (8 * 85) = 37 + 68 = $105   we simply do the maths without decimal then place on the 10's =(8 * 85) = 680 = $68 then add the $37 = $105

What is remainder R when the polynomial p(x) is divided by (2x - 1)? is (2x - 1) factor of p(x)?

p(x) = 2x² + 3x + 1

Answer :

R = 3

and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

∴ so the answer is option A

Step-by-step explanation:

Jen 's drawing shows that the lines are parallel in fact they are not parallel !  Since their slopes are not equal !

[tex]\displaystyle \left \{ {{y=2x+3} \atop {-y=2x+1}\ \ |\cdot (-1) } \right. => \left \{ {{y=\boldsymbol {2}x+3} \atop {y=\boldsymbol {-2}x-1}} \right. => -2\neq 2[/tex]

They will intersect at point A with coordinates  :

[tex]2x+3=-2x-1 \\\\ 4x=4 \\\\ x=-1 \ ; \ y=1 => A(-1 \ ; \ 1)[/tex]

Answer:

24.73

Step-by-step explanation:

h=63.4+2.41f

h=123

123=63.4+2.41f

59.6=2.41f

24.73=f

If the value of h is 123. Then the length of the femur will be 24.73 centimeters.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

h = 63.4 + 2.41 f

Where h represents the expected height in centimeters and f represents the length of the femur in centimeters.

If the value of h is 123. Then the f-value is given as,

123 = 63.4 + 2.41 f

2.41 f = 59.60

f = 24.73 cm

Assuming that the worth of h is 123. Then, at that point, the length of the femur will be 24.73 centimeters.

n ∈ natural even numbers

Step-by-step explanation:

1 + 3 + 5 + 7 + … + (2n-1)

sum of the first n terms :

Sₙ = n/2(a + Uₙ)

Sₙ = n/2(1 + 2n - 1)

Sₙ = n/2(2n)

Sₙ = n²

∴ so, the solution of n is all natural even numbers
