Im ! 16 marjorie needs to calculate how much water a cylindrical tank will hold. the tank is 9 feet high and has a diameter of 5 feet.
her work is shown below.
step 1: v = 5(2.52) (9)
step 2: v= (5)(9)
step 3: v = (3.14)(5)(9)
step 4: v=141.3 cubic feet
what error did marjorie make when calculating the volume of the tank?
in step 1, she substituted into the volume formula incorrectly.
in step 2, she calculated 2.52 incorrectly.
in step 3, the she substituted the wrong amount for .
marjorie correctly calculated the volume of the cylinder.

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

109 is the nearest whole number/final answer! : )

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
