two vertical poles of heights 12 inches and 22 inches are separated by a horizontal distance of 24 inches. what will be the distance between the tops of these poles?
Answer: 26 in.
Step-by-step explanation:
Given
Heights of Poles are [tex]12\ in., 22\ in.[/tex]
distance between them is [tex]x=24\ in.[/tex]
the difference in heights of the pole is [tex]y=22-12=10\ in.[/tex]
From the figure, using Pythagoras theorem, distance L is given by
[tex]\Rightarrow L^2=y^2+x^2\\\Rightarrow L^2=10^2+24^2\\\Rightarrow L^2=100+576=676\\\Rightarrow L=\sqrt{676}=26\ in.[/tex]
The distance between tops is 26 in.

Use Substitution to solve the following System of Equations.
y = 2x - 4
y= 12 +3
Answer:
x = 9.5
this should be the right answer if the same one you had to solve.
Step-by-step explanation:
y = 2x - 4
y = 12 + 3 combine them
2x - 4 = 12 + 3
+4 +4 The 4's cancel each other out
2x = 12 + 7 Add then divide
2x = 19
2x = 19

Bailey made risotto using a recipe that called for 223 cups of liquid. Bailey added 23 cup of liquid to the risotto every 10 minutes. Drag and drop to complete the equation to find how many times Bailey added 23 cup of liquid.
Answer:
4 times
Step-by-step explanation:
Given that :
Cups of liquid required = 2 2/3
Fraction of liquid cup added per 10 minutes = 2/3
The number of times 2/3 cups of liquid is added :
Total cups of liquid required / amount of liquid added at a time
2 2/3 ÷ 2/3
8/3 ÷ 2/3
8/3 * 3/2
24 / 6
= 4 times

Answer:
The answer is "7.036".
Step-by-step explanation:
Throughout the question by Increasing the number of standard deviations by 100 if you compose its issue as a fracture. In each cycle these were multiplied by 100, all numbers were certain ones. [tex]\frac{436.8}{62.08}[/tex] was its sum of [tex]\frac{43,680}{6,208}[/tex].
Following are the calculation to this question:
[tex]= \frac{436.8 \times 100}{62.08 \times 100}\\\\ = \frac{43680}{6208}\\\\=7.036[/tex]
