Answer:
Ha recorrido 8 km.
Step-by-step explanation:
Primero debes multiplicar el diámetro de la rueda por el número de vueltas que ha dado para encontrar cuánto ha recorrido:
80cm*10.000=80.000 cm
Ahora, debes convertir los 800.000 cm a km usando una regla de tres considerando que 1 km es igual a 100.000 cm:
1 km → 100.000 cm
x ← 800.000 cm
x=(800.000*1)/100.000
x=8 km
De acuerdo a esto, la respuesta es que ha recorrido 8 km.

Answer:
44.375sq.cm
Step-by-step explanation:
The Area of the figure = Area of the square - Area of the quadrant
Area of the square = 8 * 8 = 64sq. cm
Area of the quadrant = πr²/4 = 3.14(5)²/4
Area of the quadrant = 19.625sq.cm
Area of the figure = 64 - 19.625
Area of the figure = 44.375sq.cm

State the slope and y-intercept for the graph of the equation -8x + y = -12.
Show your work!!
Answer:
Slope is 8 and Y-Intercept is -12
Step-by-step explanation:
Move the -8x over to the right side by adding it, You are now at
y=-12+8x
Move these around and you are now at
Y=8x-12
Answer:
Step-by-step explanation:
Remark
y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.To read the slope, you must have x and its coefficient on opposite sides of the equal sign. So you get y = 8x - 12 when you add 8x to both sidesNext, the y intercept is found when x = 0y = 8x - 12y = 8(0) - 12y = - 12The y intercept is -12 or in point form (0, - 12)Answer
slope = 8
y intercept = - 12

Answer:
x = 40
Step-by-step explanation:
40° and (3x + 20)° form a straight line, and a straight line equals to 180°
=> 40 + (3x + 20) = 180
=> 3x = 120
=> x = 40
A trapezoid has a height of 6 inches, an area of 120 square inches, and one base measuring 13 inches. Find the length of the other base.
Answer:
27
Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2 Multiply by 2
2Area = (b1 + b2)*h Divide by h
2Area/h = b1 + b2 Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27
It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.
If x) = 4x2 - 16 were shifted 5 units to the right and 2 down, what would the
new equation be?
O A. h(x) = 4(x - 5)2 + 14
B. h(x) = 4(x + 5)2 - 17
C. h(x) = 4(x-18)2 - 5
D. h(x) = 4(x - 5)2 - 18
Answer:
D
Step-by-step explanation:
To shift h units to the right, replace x with x - h
To shift h units to the left, replace x with x + h.
To shift k units up, add k to the end of the formula for the function.
To shift k units down, subtract k from the end of the formula.
Example: [tex]y=x^2[/tex]
[tex]y=(x+2)^2+6[/tex] is [tex]y=x^2[/tex] shifted left 2 units and up 6 units.
Caution: the right/left shifts sometimes look backwards!

Answer:
A. 37.5
Step-by-step explanation:
Cesar does the same number of push-ups everyday. On day 7 he had done a total of 35 push-ups. How many push-up does Cesar do each day? If he continues at this rate, how many total push-ups will he have done on day 10?
Answer:
first question
5 push-ups a day
second question
50 push-ups
Step-by-step explanation:
First, you must divide 35 divided by 7 because if Cesar does the exact same amount of push-ups a day, you can divide the total number of push-ups by how many days. Which gets you your first answer 5.
Then you multiply the number of days by the number of push-ups Cesar does in a day.

A normal distribution of 10 and a standard of 1. What is the probability of selecting a number that is at most 9?
Answer:
0.15866
Step-by-step explanation:
The term at most 9 means = less than or equal to 9
This represented as x ≤ 9
We solve using the z score formula
z = (x-μ)/σ, where
x is the raw score = ≤ 9
μ is the population mean = 10
σ is the population standard deviation = 1
z = 9 - 10/1
z = -1
Probability value from Z-Table:
P(x ≤ 9) = 0.15866
Therefore, the probability of selecting a number that is at most 9 is 0.15866

Answer:
y = -1
Step-by-step explanation:
1) first, you would have to substitute x, the input, with 30, y = 14-0.5(30)
2) then, you would multiply 0.5 and 30 together which gets y=14-15
3) lastly, 14-15 equals -1 so y = -1
Answer:
Answer is -1
Step-by-step explanation:
First we know that x = 30, and in 0.5x we can plug in 30 because x = 30. So the equation is 14 - 0.5(30), now multiply 0.5 * 30 which will give you 15. Now the new equation is y = 14 - 15, 14 - 15 will give you -1. And that is y, Y = -1
