Answer:
x=18
Step-by-step explanation:
When a triangle has a midline the midline (in this case "3x-43") is 1/2 of the base of the triangle (in this case "4+x") so you can then say
4+x = 2(3x-43)
Solve that out to find that x = 18

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?
Answers
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

The highest point in Chicago is 735 feet above sea level. You can represent that numerically using .
Answers
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

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]

[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.
Susan Carver will purchase a home for $190000. She will use a down payment of 18% and finance the remaining portion at 4.2%, compounded monthly for 30 years
Answers
Answer:
$548053.69
Step-by-step explanation:
Cost of home = $190000
Down payment = 18%
Loan amount = (1 - 0.18) * 190000 = $155800
Rate, r = 4.2% = 0.042 ; compounded monthly for 30 years
Using the relation :
A = P(1 + r/n)^nt
n = number of compounding times per period = 12
A = 155800(1 + 0.042/12)^(12 * 30)
A = 155800(1.0035)^360
A = 155800 * 3.5176745
A = 548053.69
Final loan amount = $548053.69
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?
Answers
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.
