Answer:
We know that the rectangular plate has measures of:
length = 7.6 ± 0.05 cm
width = 3.1 ± 0.05 cm
(the error is 0.05cm because we know that both measures are correct to one decimal place)
First, the upper bound of the length is equal to the measure of the length plus the error, this is:
L = 7.6 cm + 0.05 cm = 7.65 cm
The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.
Remember that the area for a rectangle of length L and width W, is:
A = W*L
Then the upper bound of the area is:
A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2
median number for 46,58,72,85,93
Answer:
72
Step-by-step explanation:
You line them up from biggest to smallest and then cross off a number from both sides equally and then get your median;
46,58,72,85,93
58,72,85 (cross off 46 and 93)
72 (Cross off 58 and 85)
And then you get your answer 72

You will want to simplify those numbers (reduce to lowest terms).
Answer:
One of them is 6 - 10
Step-by-step explanation:
36/6 = 6
60/6 = 10
6 boys - 10 girls

Find the equation of the line with slope m=1 that contains the point (7,5).
Answer:
y = x - 2
Step-by-step explanation:
y = mx + b
5 = 1 (7) + b
5 = 7 + b
b = -2
So...
y = x - 2
Find the side length, a.
Round to the nearest tenth.
A=29°
b=4
c=10
a=[?]
Answer:
a = 6.8
Step-by-step explanation:
Apply the Law of Cosines
a² = b² + c² - 2bc*Cos A
A = 29°
b = 4
c = 10
Plug in the values
a² = 4² + 10² - 2*4*10*Cos 29
a² = 116 - 69.9696
a² = 46.0304
a = √46.0304
a ≈ 6.8

What is the inverse equation for f(x)=x+6
Answer:
y^-1 = x - 6
Step-by-step explanation:
change f(x) to 'y'
switch 'x' and 'y'
solve for 'y'
Answer:
Step-by-step explanation:
y = x + 6
x = y + 6
y + 6 = x
y = x - 6
f^-1(x) = x - 6

y = 5 4x+6y= 62 Solve forx
Answer:
x = 8
Step-by-step explanation:
4(8) + 6(5) = 62
32 + 30 = 62
62 = 62
Answer:
x = 8
Step-by-step explanation:
y = 5 and 4x + 6y = 62
4x + 30 = 62
Subtract 30 from each side:
4x + 30 - 30 = 62 - 30
4x = 32
Divide each side by 4:
4x ÷ 4 = 32 ÷ 4
x = 8

Answer: length = 8cm
Width = 4cm
Step-by-step explanation:
Let the width of the rectangle be represented by x.
Since the length of a rectangle is twice as long as the width of the rectangle, then the length will be: = 2 × x = 2x
Note that, Area of a rectangle = Length × Width
Therefore,
2x × x = 32
2x² = 32
Divide both side by 2
2x²/2 = 32/2
x² = 16
x = ✓16
x = 4
Therefore, width = 4cm
Since length = 2x
Length = 2 × 4cm = 8cm
Check: length × width = Area
8cm × 4cm = 32cm²
