Answer:
Question 5
We get n=42.15 and o=71.5
Question 6
We get e=15.32 and t=17.88
Step-by-step explanation:
Question 5
The triangles are similar.
So, the ratio of corresponding sides will be similar.
[tex]\frac{53}{n}=\frac{88}{70}=\frac{90}{o}[/tex]
First we will solve [tex]\frac{53}{n}=\frac{88}{70}[/tex] to find value of n.
Cross multiply
[tex]53*70=88*n\\n=\frac{3710}{88}\\n=42.15\\[/tex]
Now, we will solve [tex]\frac{88}{70}=\frac{90}{o}[/tex] to find value of o
[tex]88*o = 90*70\\o=\frac{6300}{88}\\o=71.5\\[/tex]
So, We get n=42.15 and o=71.5
Question 6
The triangles are similar.
So, the ratio of corresponding sides will be similar.
[tex]\frac{9.6}{e}=\frac{5.7}{9.1}=\frac{11.2}{t}[/tex]
First we will solve [tex]\frac{9.6}{e}=\frac{5.7}{9.1}[/tex] to find value of n.
Cross multiply
[tex]9.1*9.6=e*5.7\\e=\frac{87.36}{5.7}\\e=15.32\\[/tex]
Now, we will solve [tex]\frac{5.7}{9.1}=\frac{11.2}{t}[/tex] to find value of o
[tex]5.7*t = 11.2*9.1\\t=\frac{101.92}{5.7}\\t=17.88\\[/tex]
So, We get e=15.32 and t=17.88

https://brainly.com/question/2574086
Answer:
B
Step-by-step explanation:
Given two points, the equation of the line may be determined by,
y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)
Substituting the given values,
y - 7 = ((9 - 7) / (6 - 3))(x - 3)
Simplification will yield to an answer of,
y = 2x/3 +5

A rectangular box is 40 cm wide and 36 cm high. If the surface area of the box is 7440 square centimeters, find the length of the box.
Answer:
The length of the rectangular box is 30 centimeters.
Step-by-step explanation:
Let suppose that rectangular box is closed. The rectangular box is represented by a parallelepiped, whose surface area ([tex]A_{s}[/tex]), measured in square centimeters, is defined by the following formula:
[tex]A_{s} = 2\cdot (w\cdot h + w\cdot l + h\cdot l)[/tex] (1)
Where:
[tex]w[/tex] - Width, measured in centimeters.
[tex]h[/tex] - Height, measured in centimeters.
[tex]l[/tex] - Length, measured in centimeters.
If we know that [tex]A_{s} = 7440\,cm^{2}[/tex], [tex]w = 40\,cm[/tex] and [tex]h = 36\,cm[/tex], then the length of the rectangular box is:
[tex]2880 +80\cdot l + 72\cdot l = 7440[/tex]
[tex]152\cdot l = 4560[/tex]
[tex]l = 30\,cm[/tex]
The length of the rectangular box is 30 centimeters.
