Answer is
= 1.24*5+1.1*2.20+4.5*0.68
= <u>11.68</u>
Answer:
1) View image attached
2) -3, -2.5, -1, 2, 5
3) -2.5
Step-by-step explanation:
1) Draw a number line, an image is shown below with the number line. You then put "points" on the values that you are plotting. This is also shown in the image attached.
2) The ones with the "-" are negative, meaning that they are below 0. These will always be smaller than those without a "-" sign. In addition to this, the way negative numbers work in terms of least to greatest is completely flipped. For example, -5 is greater than -10, and -10 is less than -5. If the numbers were positive, 5 would be less than 10 and 10 would be greater than 5.
3) The value that isn't an integer is the one that isn't a whole number. In those answer choices you gave, the only one with a decimal is -2.5 (as indicated by the ".5"
Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
Step-by-step explanation:
f(x)=2*,
it will mean, f(7/2)=2
f= 4/7
The volume would be V = (side of base)^2 * (height). The height would be 3. To see this, make yourself a model if need be. Assuming that the dimensions of the "square piece of cardboard" are x by x, then the length (or the width) of a side of the square bottom would be x-3-3, or x - 6.
So: V = (x-6)^2*3 = (area of base)*(depth of box)
= 3(x-6)^2 (answer)
