Answer:
Step-by-step explanation:
[1] x = 10
[2] 3x + 5y = 20
0? + x = 10 5? + 3x = 20
Step 1: make seedlings in each row equal, means find out the common factors of each kind of seedlings:
42 pine seedlings: 2, 3, 6, 7, 14, 21
30 oak seedlings: 2, 3, 5, 6, 10, 15
Step2: the greatest number of those seedlings above is 6, and the answers are as follows:
1/ greatest number of each row is 6
2/ pine: 42/ 6= 7; oak: 30/ 6= 5
Answer:
4
Step-by-step explanation:
12/3=4
The hanger diagram ideally should be in balance with all the shapes hung on it.
On the left side, it shows that the circles are 9 grams and the squares are 12 grams. The triangles are 2t grams. Therefore, on the left side we have,
9 + 12 + 2t
On the right side, it shows the circles are 6 grams and the squares are 6 grams, while the triangles are 5t grams. Therefore on the right side we have
6 + 6 + 5t.
For the hanger to be in balance, we should have
Answer:
<em>Diameter Length: ( About ) 5.4 km; Option B</em>
Step-by-step explanation:
~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~
1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒
<em>radius = ( About ) 2.7</em>
2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km
<em>Diameter Length: ( About ) 5.4 km</em>
