Answer:
12.7 miles
Step-by-step explanation:
Note the place values:
12.654
1 (tens value)
2 (ones value)
.
6 (tenths value)
5 (hundredths value)
4 (thousandths value)
~
You are rounding to the nearest tenths value. Note that when rounding, you look at the value directly next to the one you are solving for. If the digit is 5 or greater, round up. If it is 4 or less, round down.
In this case, the hundredths value is a 5, so round up.
12.654 miles rounded to the nearest tenths value is 12.7
12.7 miles is your answer.

Write the equation of the line through the given point. Use slope-intercept form.
3
(-4,6); perpendicular to y = -
2x+3
Write an equation for the line in slope-intercept form.
(Simplify your answer. Use integers or fractions for any numbers in the equation)
Answer:
2y=x+16
Step-by-step explanation:
condition for a perpendicular line to the previous line is that the gradient M1=-1/M2. looking at the question above the equation of the line given y=-2x+3 that is the first M1=-2. so to get the gradient M2 of the line perpendicular, then M2=-1/-2=1/2. so M2=1/2. so the equation of the new line is y=1/2x+C. so we can find C. since the line passes through (-4,6). when x=-4, y=6, 6=1/2(-4)+C..C=6+2=8. so the equation of the new line y=1/2x+8 we can multiply via 2. so we have 2y=x+16
the equation is 2y=x+16

D is between C and E, CD = x 2 , CE = 32-2x, and DE = 12x. Find CD, DE, and CE.
Answer:
CD = 4DE = 24CE = 28Step-by-step explanation:
The segment addition theorem tells you ...
CD +DE = CE
x^2 +12x = 32 -2x
Subtract the right side to put this in standard form.
x^2 +14x -32 = 0
(x +16)(x -2) = 0
x = -16 or 2
In order for DE to have a positive length, we must have x > 0. So ...
CD = x^2 = 2^2 = 4
DE = 12x = 12(2) = 24
CE = 32 -2x = 32 -2(2) = 28

Answer:
[tex]\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}[/tex]
Step-by-step explanation:
Using Pythagorean Theorem first to find EC
[tex]\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm[/tex]
Given that:
AE = EC
AE = 12 cm
Now,
AB = AE + EB
AB = 12 + 5
AB = 17 cm
ABCD is a trapezoid / trapezium
So,
Area of Trapezium = [tex]\sf \frac{AB+DC}{2} (EC)[/tex]
Where AB = 17 , DC = 8 and EC = 12
Area of Trapezium = [tex]\sf \frac{17+8}{2} ( 12)[/tex]
Area of Trapezium = (25)(6)
Area of Trapezium = 150 cm²
Classify the equation, 7x + 2 = 7x - 3, as having one solution, no solution, or infinitely many solutions.
The equation has
Answer:
No solution
Step-by-step explanation:
To solve this, we subtract 7x from both sides to get 2=-3. Since 2 does not equal to negative 3, there is no solution.
An angle measures 50° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
20° and 70°
Step-by-step explanation:
Complementary angles sum up to 90°.
The angle = x
Its complement = x + 50
x + x + 50 = 90
2x = 40
x° = 20°
20+50=70
Answer: 70° and 20°
Step-by-step explanation:
Complementary angles add up to 90 degrees and we now that one angles measure is 50 degrees less than the other. So we can represent it by the expression x = y -50 where x and y are the two angles. We don't the value of y so it will be just y .
Now we know that if we add them,they will equation 90 degrees so we can represent it by the equation,
y + y-50 = 90 Now solve for y
2y - 50 = 90
+50 +50
2y = 140
y = 70
Now we know one angles is 70 degrees and the other is 50 less than it so the other angle will be 70 - 50 = 20

ugh no body knows this? Suppose a square garden represented by 16x2 ft2. a. What is the length of each side? b. What is the perimeter of the garden? c. If each side was increased by 5 feet what would be the new perimeter?
Answer:
A. [tex]4x[/tex]
B. [tex]16x[/tex]
C. [tex]16x+20[/tex]
Step-by-step explanation:
A square's area will be the length of each side squared (that's why it's called squared).
Since we know the area, we can find the square root of [tex]16x^2[/tex] to find the length of each side.
We know that [tex]4^2 = 16[/tex] and [tex]x^2 = x^2[/tex], so [tex]4x\cdot 4x[/tex] should be equal to [tex]16x^2[/tex].
This means the side length is [tex]4x[/tex].
The perimeter of a square will be 4 times it's side length. We know the side length, so the perimeter is [tex]4x \cdot 4 = 16x[/tex].
If we added 5 to the length of each side, the new side length would be [tex]4x + 5[/tex]. Again, the perimeter is 4 times the side length so the perimeter would be [tex]4(4x + 5) = 16x + 20[/tex].
Hope this helped!
