Answer:
2000 students (840 are girls and 1160 are boys)
Step-by-step explanation:
Let X be the total number of students. Let G and B stand for the total number of Girls and Boys, respectively.
We are told that 58% are boys:
0.58X = B
This means 42% are girls:
0.42X = G
We are told that G = 840
0.42X = 840
X = 2000 students
====
Since 0.58X = B
0.58(2000) = 1160 boys
1160 boys
840 girls
2000 total students

Answer:
<h2>f(-3) = 43</h2>
Step-by-step explanation:
f(x) = 4x² + 7
To find f(-3) substitute the value of x that's - 3 into f (x) that's replace every x in f (x) by - 3
We have
f(-3) = 4(-3)² + 7
= 4(9) + 7
= 36 + 7
We have the final answer as
<h3>f(-3) = 43</h3>

Well, we know 1 yard is 3 feet, so 2 yards is 6 feet. That makes Jorge's sleeping bag longer than Jim's. (6 feet is longer than 5 feet)
We also know that 1 yard is 36 inches, so 2 yards is 72 inches. That makes Jorge's sleeping bag longer than Steven's. (72 inches is longer than 68 inches)
Since Jorge's sleeping bag is longer than both Jim's and Steven's, Jorge's sleeping bag is longer.
