Answer:
15(b+2) + 15 + 2b-9 +b = 90
Step-by-step explanation:
Essentially you add up all of the values and make it equal to 90, then solve for b
15(b+2) + 15 + 2b-9 +b = 90
15b + 30 + 15 + 2b - 9 + b = 90
18b + 30 + 15 - 9 = 90
18b + 36 = 90
18b = 54
b=3

If the measure of Angle F G H is 64 degrees and the measure of Angle E G D is (4 x + 8) degrees, what is the value of x? Lines E H and D F intersect at point G. 14 18 64 116
Answer:
x = 14
Step-by-step explanation:
Angle FGH and EGD are vertical angles, so they will have the same measurement.
so basically 64 = 4x + 8
subtract the 8 = 56
divide 56 by 4
x = 14

A local pet store buys cans of dog food for $0.43. They sell them for 65% more for profit. If a customer buys 14 cans of dog food, how much will it cost? (Please provide a simple explanation if possible.)
Answer:
$9.94
Step-by-step explanation:
.43¢= 1 can
65% markup can be done by .43 + (.43×.65)
that equals .71¢ for 1 can after the markup.
multiply .71× 14 = $9.94

The width of the fountain in Luke's drawing from the example is 2 cm. What is the width of the fountain in Isabella's scale drawing?
Answer:
2.5cm
Step-by-step explanation:
If Luke's scale for his drawing is 5m to 2cm, then it means that every 2cm on Luke's scale drawing represents 5m in real life. So since the width of the fountain is 2cm, the actual fountain width must be 5m. As established in the example, Isabella's scale factor from drawing to real life is 6/3=2, which means any measurement in cm on her drawing can simply be multiplied by 2 to obtain the real life measurement in m. So, to convert back the other way, from real-life to drawing, we just need to divide the value by 2 instead of multiply. So, if the real life value is 5m, then the width on her scale drawing should be 5/2 = 2.5cm.
Hope this helped!
Using proportions, it is found that:
The width of the fountain in Isabella's scale drawing is of 1.6 cm.
-----------------------------------
This question is solved by proportions, using a rule of three.
Isabella's scale is of 6m to 3cm, that is, 2m to 1cm.Luke' scale is of 5 m to 2 cm, that is, 2.5m to 1 cm.From this, it can be taken that a drawing of 250cm in Luke's scale is of 200 cm in Isabella's scale.What is the width of Isabella's drawing, considering that Luke's width is 2 cm?200 cm - 250 cm
x cm - 2 cm
Applying cross multiplication:
[tex]250x = 400[/tex]
[tex]x = \frac{400}{250}[/tex]
[tex]x = 1.6[/tex]
The width of the fountain in Isabella's scale drawing is of 1.6 cm.

Okay, suppose You know, 32 is between what? two perfect squares? What are perfect squares? Well, a number of times itself gives me, so like, four times itself is 16, 5 times itself is 25, 6 times itself is 36, So 32 is the closest to 25 In 36. So I'm gonna put 25 Smalling number and 36. And what I could do with this inequality is I could take the square root of all three Side. So square to 25 is in between square to 32 is in between square to 36. So square 25. What himself gives me 25 5 Is in between the square to 32 and what himself gives me 36 6. So that must mean the Square 32 is in between the Avengers five and so.
