Answer:
<u>145 people were surveyed</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Percentage that indicated they preferred walking to running = 90%
2. If 130 people preferred running to walking, how many people where surveyed?
For answering this question, we will use the Rule of Three simple, this way:
x = Number of people surveyed
90 * x = 130 * 100
90x = 13,000
x = 13,000/90
x = 144.44
But we need a whole number for an accurate answer, so we round the value of x to the next whole number.
<u>145 people were surveyed</u>
Answer:
D (-1, 5)
Step-by-step explanation:
In reflection along the x-axis,
x-coordonate remains unchanged and y-coordinate gets multiplied by -1
Answer:
{x,y}={1,−3}
Step-by-step explanation:
19 + 5a⁴ - 3b²
19 + 5(2)⁴ - 3(-4)²
19 + 5(16) - 3(16)
19 + 80 - 48
99 - 48
51
Answer:
(-1,1), (1,3), (2,2)
Step-by-step explanation:
To dilate an object, we need to multiply the x and y values by the given scale factor.
In this case the scale factor is 1/3 --> 1/3(x, y)
Before-> After dilation
1/3(-3,3) = (-1,1)
1/3(3,9) = (1,3)
1/3(6,6) = (2,2)
