Answer:
Creo que con 15
Step-by-step explanation:
50 -------> 100%
X ---------> 30%
X = (50*30)/100
X= 15 boys
Sample:
No, Felicia’s answer is not correct. She should have divided by 2, not multiplied. 30 divided by 2 is 15. So 15 of the 50 students in the band are boys.

I need help some help please
Answer:
1. no, 2. yes
Step-by-step explanation:
You need to use the triangular inequality thereom, which goes by if any side lengths are added together, they are greater than the remaining one. So, for number one, although 20+9=29>8 and 20+8=28>9, 9+8<20 since 9+8=17, which is less than 20. For number two, yes because 1) it is a right triangle triple and 2) 3+4=7>5, 4+5=9>3, and 5+3=8>4.
Answer:
Number 1 is Not a triangle so No and you don’t need to classify becuase it’s not aa triangle
Number 2 is a triangle becuase its ta Pythagorean triplet and even if you checK, it adds up.
Step-by-step explanation:
1) So using Pythagorean Theorem
8^2+9^2=20^2
64+91=400
That is not true
2) 3^2+4^2=5^2
9+16=25
That is true

4. Emilio asks his classmates what month they were born. He finds that 15
out of 125 classmates were born in July. If there are 1,280 students in
Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected

Katy bought a $76 dress at 33% off and a $52 pair of shoes at 15% off. If
sales tax is 6.75% how much did she pay in total?
Answer:
101.54
Step-by-step explanation:
Answer:
$103.21
Step-by-step explanation:
33% of 76=$25.08 then 76-25.08=$50.92
12% of 52=$6.24 then 52-6.24=$45.76
50.92+45.76=$96.68
6.75% of 96.68=$6.525-->$6.53
96.68+6.53=($103.21)

Step-by-step explanation:
x – 7y = –11
5x + 2y = -18
Answer:
hope this help you
Step-by-step explanation:
Simplifying
X + -7y = -11
Solving
X + -7y = -11
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '7y' to each side of the equation.
X + -7y + 7y = -11 + 7y
Combine like terms: -7y + 7y = 0
X = -11 + 7y
Simplifying
X = -11 + 7y
------------------------------------------------------------------------------------------------------------
Solving
5x + 2y = -18
Solving for variable 'x'.
Add '-2y' to each side of the equation.
5x + 2y + -2y = -18 + -2y
Combine like terms: 2y + -2y = 0
5x = -18 + -2y
Divide each side by '5'.
x = -3.6 + -0.4y
Simplifying
x = -3.6 + -0.4y
