Felicia wanted to find the number of boys in the school band if 30% of the 50 students are boys. Is her answer correct? Explain why or why not.

Answers

Answer 1

Answer:

Creo que con 15

Step-by-step explanation:

50 -------> 100%

X ---------> 30%

X = (50*30)/100

X= 15 boys

Answer 2

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.

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

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

Answers

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

x – 7y = –11
5x + 2y = -18

Answers

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

Identify an equation in point-slope form for the line parallel to y =-2/3x+8 that
passes through (4,-5).

Answers

first find the slope (which is -2/3)

then plug into point-slope formula using the coordinates. if you dont remember point-slope is “y-y1 = m (x-x1) where y1 being the y of the coordinate while x1 being the x of the coordinate and m being the slope.

plug it in to get “y+5 = -2/3 (x-4)

that’s the point-slope form
