Answer:
10.30
Step-by-step explanation:
Pythagorean Theorem is [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]. The short leg(a) is 5 units long and the long leg(b) is 9 units long. CD is the hypotenuse, the longest side (c).
[tex]5^{2}[/tex] +[tex]9^{2}[/tex] =[tex]c^{2}[/tex]
25+81=[tex]c^{2}[/tex]
106=[tex]c^{2}[/tex]
[tex]\sqrt{106}[/tex] = [tex]\sqrt{c^{2} }[/tex]
10.29563014 = c
Rounded to the nearest hundredth, 10.30
To check this is correct, the hypotenuse is the longest side, and 10.30 is longer than 5 and 9.

Answer:
432 more emails
Step-by-step explanation:
I) Find decimal of remaining inbox:
88% = 0.88
1 - 0.88 = 0.12
II) Find TOTAL capacity of inbox emails:
3168 / 0.88 = 3600
III) Find remaining capacity of emails:

Step-by-step explanation:
The highest point in Chicago is 735 feet above sea level. You can represent that numerically using .
Answer:
+735 feets
Step-by-step explanation:
Points or position above sea level are denoted with positive elevation values while points or positions below sea level are denoted by negative values. The sea level position itself could be viewed as a midpoint such as the position of 0 on a number line ; where distances to the right are positive and distances to the left are negative.
Hence, a point which is said to be 735 feets above sea level would have an equivalent numeric representation of +735 feets

how do you solve 3 divided by x -1 = x + 1
Answer:
multiply (x-1) to both sides and then subtract three from both sides
3 = (x-1)(x+1)
3 = (x^2 -1)
0 = x^2 - 4
(x-2)(x+2) = 0
x = 2
x = -2

9. In a home economics class, 6 girls worked together and sewed a dress in 4 days. How long
would it have taken for 4 girls to make the same dress?
Answer:
6 days.
Step-by-step explanation:
Given that in a home economics class, 6 girls worked together and sewed a dress in 4 days, to determine how long it would have taken for 4 girls to make the same dress, the following calculation must be performed:
X / 6 = 4
X = 4 x 6
X = 24
24/4 = 6
Thus, the 4 girls will take 6 days to make the same dress that 6 girls made in 4 days.

E = MV^2 ÷ 2 + mgh, If M=20, h=15, E=4900, g=9.8. Find V
Answer:
V = 14 m/s
Step-by-step explanation:
[tex]E = MV^2 ÷ 2 + mgh \\ \\ 4900 = 20V^2 ÷ 2 + 20 \times 9.8 \times 15 \\ \\ 4900 = 10V^2 + 2,940\\ \\ 4900 - 2940 = 10V^2 \\ \\ 1960 = 10V^2 \\ \\ V^2 = \frac{1960}{10} \\ \\ V^2 = 196 \\ \\ V = \sqrt{196} \\ \\ V = 14 \: m {s}^{ - 1} [/tex]

Answer:
9 • 9 • 9 • 9 • 9 • 9
Step-by-step explanation:
Given data
Value= 9⁶
The equivalent to the above expression is the dot product of
9*9*9*9*9*9
Hence the correct option is the third option

If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT
Answer:
x = 6
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 25 when y = 100 , then
100 = 25k ( divide both sides by 25 )
4 = k
y = 4x ← equation of variation
When y = 24 , then
24 = 4x ( divide both sides by 4 )
6 = x
How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?
Answer:
186.7 cubes
Step-by-step explanation:
How many LaTeX: \frac{1}{3}1 3 inch cubes does it take to fill a box with width LaTeX: 2\frac{2}{3}2 2 3 inches, length LaTeX: 3\frac{1}{3}3 1 3 inches, and height LaTeX: 2\frac{1}{3}2 1 3 inches?
Step 1
We find the volume of the box
= Length × Width × Height
Length = 3 1/3 inches = 10/3 inches
Width = 2 2/3 inches = 8/3 inches
Height = 2 1/3 inches = 7/3 inches
The volume of the box =
10/3 inches × 8/3 inches × 7/3 inches
= 560/9 cubic Inches
= 62 2/9 cubic inches
Step 2
How many 1/3 inch cubes would fill the box.
This is calculated as:= 62 2/9 cubic inches/ 1/3 inches
= 560/9 ÷ 1/3
= 560/9 × 3/1
= 186.66666667 cubes
Approximately = 186.7 cubes
