convert 30 mph to meters per s3cond and round to the nearest tenth
Answer:
13.4
Step-by-step explanation:
Divide the number of meters in a mile (1,609.344) by the number of seconds in an hour (3,600): 1,609.344 divided by 3,600 equals 0.44704. One mile per hour equals 0.44704 meters per second.

Sqrt 80 = 4 sqrt 5
Step-by-step explanation:
Sqrt [(6-2)^2 + (4 - - 4)^2
= sqrt. (4^2 + 8^2) = sqrt (16 + 64)
= sqrt 80
= 4 sqrt 5
A polynomial function h(x) has a zero of x = 3 - 41 with a multiplicity of one. Certain values of h() are given in the following table.
x h(x)
-5 0
-2 3
-1 0

The degree of a polynomial is the value of the highest degree of a monomial in the polynomial
The degree of the polynomial h(x) is 5
The reason the above value is correct is as follows;
Given;
A zero of a polynomial function h(x) is the imaginary number, x = 3 - 4·i
The multiplicity of the root at x = 3 - 4·i is One
The given table showing the real roots of the polynomial is presented as follows;
[tex]\begin{array}{|c|cc|}\mathbf{x}&&\mathbf{h(x)}\\\displaystyle -5&&0\\-2&&3\\-1&&0\\1&&2\\4&&0\\7&&6\\10&&0\end{array}\right][/tex]
Required:
To find the degree of the polynomial, h(x)
Solution:
The maximum number of roots of a polynomial is given by the degree of the polynomial
The number of roots is given by the number zeros
The maximum number of roots an nth degree polynomial can have = n roots
From the given table, the number of zeros = 4 (each with multiplicity of one) = The number of real roots
Therefore, the total number of roots of the polynomial = 4 + 1 = 5 = The (minimum possible) degree of the polynomial
The degree of the polynomial = 5

PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE HELP DECIMAL WORD PROBLEM INTO EQUATION
Answer:
136 miles
Step-by-step explanation:
Write an equation to represent the cost of the rental, and then solve the equation to find the number of miles.
Let x = number of miles.
The total cost is the cost per mile plus the base fee.
1 mile costs $0.90
2 miles cost $0.90 * 2
x miles cost $0.90 * x, or simply 0.9x
The base fee is $16.95, so the total to rent for x miles is 0.9x + 16.95
The equation
c = 0.9x + 16.95
gives you the cost, c, for a rental of x miles.
We are told the total cost was $139.35. Replace c with 139.35, and solve for x, the number of miles.
139.35 = 0.9x + 16.95
Switch sides.
0.9x + 16.95 = 139.35
Subtract 16.95 from both sides.
0.9x = 122.4
Divide both sides by 0.9
x = 122.4/0.9
x = 136
Answer: 136 miles

Find the m GEOMETRY 9th:)
Answer:
∠ WOT = 85
Step-by-step explanation:
To find the measure of ∠WOT
we know that ∠UOV is 180 in the pic
so by letting ∠WOT = x
∠UOT + ∠WOT + ∠WOV = 180
30 + x + 65 = 180
95 + x = 180
x = 180-95
x = 85
so ∠ WOT = 85
(EASY) In a rectangle, the length is 5 metres more than the width The perimeter of the rectangle is 70 metres Calculate the measurments for the length and width
Answer:
15 m and 20 m
Step-by-step explanation:
Let the width be x
Length = x + 5
Perimeter = 2(l + b)
70 = 2(x + 5 + x)
70/2 = 2x + 5
35 = 2x + 5
35 - 5 = 2x
30 = 2x
30/2 = x
15 = x
Length = x + 5 = 20 m
Breadth = x = 15 m

Objective; Translating points
A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.
Algebracially:
[tex](x + h)[/tex]
where h is the amount of units we move right or left
and
[tex](y + k)[/tex]
where k is the amount of units we move up or down
For 1. We are asked to translate the figure 3 units up and 7 units to the left.
7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is
Our new coordinates
E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).
2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.
So our new coordinates is
T' (1,3)
U' (4,3)
V'(4,5)
W'(1,5)

To take a taxi, it costs $3.00 plus an additional $2.00 per mile traveled. You spend $20 on the taxi. How many miles did you go?
Answer: 8.5 miles
Step-by-step explanation:
Given information
Base fee = $3.00
Fee per mile = $2.00
Distance = x
Total money spend = $20
Set equation
3 + 2x = 20
Subtract 3 on both sides
3 + 2x - 3 = 20 - 3
2x = 17
Divide 2 on both sides
2x / 2 = 17 / 2
[tex]\boxed{x=8.5}[/tex]

Can someone explain me how to do this
8) v = -3
9) m = 4
Explanation:
8)
[First distribute the factored terms on the left side of the equation]
2(v + 4) + 3(4v + 5) = -19 →
2(v) + 2(4) + 3(4v) + 3(5) = -19 →
2v + 8 + 12v + 15 = -19 →
[Next, add the like terms together]
(2v + 12v) + (8 + 15) = -19 →
14v + 23 = -19 →
[Subtract 23 from both sides to isolate the constant term]
14v + 23 – 23 = -19 – 23 →
14v = -42 →
[Lastly, divide both sides by 14 in order to obtain the value of v from the coefficient of 14 in 14v]
14v / 14 = -42 / 14 →
v = -3
9)
[Start by distributing the factored term on the left side of the equation]
2(m – 1) = 10 – m →
2m – 2 = 10 – m →
[Next, add m to both sides in order to isolate the m term and remove -m from the right side of the equation]
2m – 2 + m = 10 – m + m →
3m – 2 = 10 →
[Add 2 to both sides to isolate the constant term and remove -2 on the left side of the equation]
3m – 2 + 2 = 10 + 2 →
3m = 12 →
[Finally, divide by 3 on both sides in order to reduce the coefficient of 3 in 3m to get m]
3m / 3 = 12 / 3 →
m = 4

please help me quickly
Answer:
look we solve it without options
4 - 2x = 24
4 - 2x -4 = 24 -4
SO FIRSTLY SUBTRACT 4
-2x = 20
-2x /-2 = 20 /-2
SO DIVIDE BY -2
X = - 10
So analyse options and u will know that option b is correct :))
A line passes through the point (8,6) and has a slope of -3/4
Answer:
y = -3/4x + 12
Step-by-step explanation:
Use slope intercept form [ y = mx + b ], the point given, and the slope to find the y-intercept.
6 = -3/4(8) + b
6 = -6 + b
12 = b
Now input the values we are given and solved for into the formula.
y = -3/4x + 12
Best of Luck!
