Answer:
The answer is 2
Step-by-step explanation:
The hypotenuses of the triangles are different. One is 4 and the other is 5.
Lets use ratios to find the relationship of the hypotenuse and the base.
2.5:5
Turn this into a fraction
2.5/5
Now divide
2.5/5 = 0.5
The base of the triangle is half the length of the hypotenuse.
So 4 is x’s hypotenuse so:
4 x 0.5 = 2
X = 2
Graph the two points and you'll see that the radius is 3.
C=2(pi)r
C = 2(3.14)(3)
C = 18.84
Answer:
20/25
Step-by-step explanation:
divide the denominators
25/5=5
multiply the numerator
4*5=20
Answer:
y = 4x + 14
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 7 ← is in slope- intercept form
with slope m = 4
• Parallel lines have equal slopes , then
y = 4x + c ← is the partial equation
to find c substitute (- 3, 2 ) into the partial equation
2 = - 12 + c ⇒ c = 2 + 12 = 14
y = 4x + 14 ← equation of parallel line
Answer:
<h2>Amanda needs 72 grams of paint</h2>
Step-by-step explanation:
Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.
Now, there remain 3 faces per cube to be painted, which means there are 24 faces.
Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?
Therefore, Amanda needs 72 grams of paint for the unpainted surfaces.
