Answer:
259
Step-by-step explanation:
[] To round, you look to the number placed right of the value you are rounding. If it is greater than or equal to 5, you round up. If it is less than or equal to 4, the number stays the same.
[] The whole number is the number before the decimal, we will round it off at the ones place.

Answer:
259.
Step-by-step explanation:
All we need to do is,
Look at the number after the decimal place, Check to see if it is greater or less than 5.
Numbers that are less than 5 will be decreased and numbers that are 5 and over will be increased. We have a 6 after the decimal point so we are going to round up.
258.68, The number just before the decimal point is 8. One more than 8 is 9 so our answer will be 259 as a whole number with no decimals!
Hope that helps. x

Multiple Representations Hexagon
ABCDEF has vertices A(-2, 4), B(0, 4), C(2, 1),
D(5, 1), E(5, -2), and F(-2, -2). Sketch the
figure on a coordinate plane. What is the
area of the hexagon?
Answer: area = 30 square units
The diagram is below. Ignore point G and the red dashed line when drawing the final hexagon needed.
======================================================
Explanation:
On the grid your teacher has given you, plot the 6 points. Then connect them to form hexagon ABCDE. All of this is shown in blue in the diagram below.
Let's add point G as shown in red. I'll connect G to point C with a red dashed line. These will be temporary and erased later. Though if your teacher doesn't mind you leaving it in (so you can show your steps), then its probably not a bad idea to keep it. It's best to ask your teacher.
Anyways, the red segment GC splits the original hexagon into a trapezoid up top and a rectangle down below.
------------
The trapezoid has the parallel bases of b1 = GC = 4 and b2 = AB = 2. The height is h = GA = 3
This leads to,
area = h*(b1+b2)/2
area = 3*(4+2)/2
area = 3(6)/2
area = 18/2
area = 9
Trapezoid ABCG has area of 9 square units.
-----------
The rectangle has length EF = 7 and width ED = 3
area = length*width
area = 7*3
area = 21
Rectangle DEFG has area of 21 square units.
------------
Add up those two area results to get the area of the overall hexagon.
trapezoid + rectangle = 9 + 21 = 30 square units.
4. In which quadrant, or on which axis, is the point located?
(-15, 0)
Answer:
x axis
Step-by-step explanation:
Answer:
Negative side of the x-axis
Step-by-step explanation:
-15 is x and -15 is to the left of the origin
0 is y so it does not move up or down.
7. A square backdrop is made of 40 ft of fabric.
What is the closest length of one side of the
backdrop? Round to the nearest tenth.
Answer:
6.3 ft
Step-by-step explanation:
Square = 4 equal sides
So, we have to find out what multiplied by itself will = 40
40 = x * x = x^2 OR sqrt(40)
sqrt(40) = 6.32455532034 --> 6.3
Find a rational number between 5/7 and 3/4
Answer:
41/56
Step-by-step explanation:
The LCD is 7×4 = 28. With that denominator, the two fractions are ...
5/7 = 20/28
3/4 = 21/28
The average of the two values will be ...
(5/7 +3/4)//2 = (20 +21)/28/2 = 41/56
_____
Additional comment
5/7 ≈ 0.714285... (6-digit repeat)
3/4 = 0.75
Then numbers like 0.72 = 18/25, or 0.73 = 73/100, or 0.74 = 37/50 will all be between the given fractions.
Of course, any terminating or repeating decimal in that range will also be a rational number. For example, 0.727272727272... = 8/11 will be a rational number in the required range.

Solve the inequality f/2 - 22 < 48
Answer:
The answer is f < 140
Step-by-step explanation:
f/2 – 22 < 48
f/2 – 22 + 22 < 48 + 22
f/2 < 70
f < 70 (2)
f < 140
Thus, The answer is f < 140

Hello can someone please help me with these math estimates I would really appreciate it.
Answer:
see below
Step-by-step explanation:
The graph is hard to see but this is an estimate from what I can tell:
(a) (0, 5)
(b) (4, 0)
(c) -10
(d) 15
(e) -8
The input is the x-value and the output it the y-value, so for question (c) find where y=18 (place your ruler horizontally on the graph at y=18) and then find the value of x where y=18 on the line.
Kendall rode her scooter 5 miles in 3/4 hour. What is her average speed in miles per hour?
Can someone please help me, i dont now how to do it
Answer:
32 in²
Step-by-step explanation:
For this rectangular prism, we will assume the "base" is the face at the bottom. Its dimensions are 'a' and 'b', which is to say it is 5 inches wide and 3 inches deep. The perimeter of the base is the sum of its side lengths, so is ...
P = 5 in + 3 in + 5 in + 3 in = 2(5 in +3 in) = 2(8 in) = 16 in.
__
The height of the prism is 'c', which is given as 2 inches.
The lateral area is the product of the base perimeter and the height, as the problem statement tells you.
LA = Ph
LA = (16 in)(2 in) = 32 in²
The lateral area is 32 square inches.
You have a pet hamster and a pet mouse. The hamster weighs 4/16 of a pound. The mouse weighs 1/16 of a pound. How much more does the hamster weigh than the mouse?
Answer: the hamster weighs 3/16 more than the hamster
Step-by-step explanation: there is already a common denominator so you just do 4 minus 1 equals 3 therefore you have 3/16

Which glide reflection describes the mapping ABC Def
Answer:
B
Step-by-step explanation:
Point B is above AC. Corresponding point E is below the corresponding segment DF. This means the reflection is vertical, across a horizontal line.
In order to get the figure to its final position, it must be translated to the right by 6 units. This translation matches choice B.
(x, y) ⇒ (x +6, y -1), and reflected across y = 0

I really need this pls A certain brand of coffee costs $6.99 for 24.2 ounces. What is the unit rate? Enter your answer, rounded to the nearest cent, in the box.
Answer: $0.29 per oz, or 29 cents per oz.
Step-by-step explanation:
To find a unit rate, divide the numerator AND denominator by the denominator. The rate is $6.99/24.2 ounces. We will divide $6.99 by 24.2, and 24.2 ounces by 24.2. The answer will be $0.288843/1 ounce. If we round, it will be $0.29/1 ounce.
parallel, perpendicular or neither x = -4 and x = 9
analyze problem
x=-4 has slope of 0
x=9 has a slope of 0
therefore, same slopes represent parallel lines, so parallel
Answer:
Parallel
Step-by-step explanation:
x=-4 is a vertical line and x=9 is also a vertical line
So, they are the same line meaning they are parallel lines

This is a form of an equation that gives you lots of information about the parabola (that's the name of the v-ish/u-ish curve shape on the graph)
y = a(x - h)^2 + k
The number in front of the parentheses tells you if the curve is stretched or smashed and if negative (like these) its flipped down so its opening downward.
The number inside the parenthesis added to or subtracted from the x, will tell you if the graph is translated (shifted or slid over) left or right. This left or right shift is kind of backwards from what you might think. An x - 1 means its shifted RIGHT. An
x + anumber will shift it left. Kind of backwards. But there are math reasons. Just memorize the backwardness of horizontal shifts.
The number added on to the end of the equation will translate (slide/shift) the parabola UP for " + anumber" and DOWN for "- anumber" It goes in the direction you would expect for vertical shifts.
The image in the question has been flipped, so start with a negative. Shifted right one, so (x - 1) and lastly, shifted up 5 so tack on a + 5 at the end.
What is the variable in the equation 2 - 3x = 14
Answer:
x
Step-by-step explanation:
The token that is not a numerical value (2, 3, 14), an operation (-), or a relation symbol (=) is the variable. It is "x".
The variable is x.
