Answer:
900
Step-by-step explanation:
The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.
Let the number of people who own a flip phone=x
If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600
To find x, we express the ratio and population as an equality.
5:3=x+600:x
Expressing the ratios as fractions would give:
Next, we cross multiply
5x=3(x+600)
Open the brackets by expansion.
5x=3x+(3 X 600)
5x=3x+1800
Subtract 3x from both sides.
5x-3x=3x-3x+1800
2x=1800
Divide both sides by 2
x=900.
Since x=900, the number of people who own a flip phone is 900.
Step-by-step explanation:
This is an acute triangle
Answers:
<h2>27. D</h2><h2>29. C</h2><h2>30. H</h2><h2>31. B</h2><h2>35. C</h2>
Step-by-step explanation:
There is no work to show for 27 & 29
30. Subtract 3 from 32 mi/gal to get the minimum number of miles a gallon, which is 29. Multiply this by 11 to get 319. Add 3 to 32 to get the largest number of mpg, which is 35. Multiply by 11 to get 385.
31. Multiply 60 by 112 to get the amount of cents in 112 dollars, which is 6.720.
35. Try out the numbers, until one works.
72 + 76/2 = 74 ✖
72 + 84/2 = 78 ✖
72 + 88/2 = 80 ✔️
An 80 is a B, so Paula needs at least an 88 to get a B in the class.
HOPE THIS HELPS :)
We know that
AE*EC=DE*EB-----------> <span>String theorem
AC=8 in----------> AE=AC/2----------> AE=4 in
EC=AE-----------> EC=4 in
BE=2.5 in
DE=?
DE=(AE*EC)/EB----------> DE=</span>(4*4)/2.5---------> DE=6.4 in
<span>
then
diameter=DE+EB--------> 6.4+2.5=8.9 in
the answer is
the diameter is 8.9 in
