Answer:
x = 910/153
Step-by-step explanation:
Multiply both sides by 7 (z = 5, so 6 +5/5 = 6 + 1 = 7):
7(3x+50*3x)/6+5/5 = 130*7
Simplify:
153x = 910
Divide by 153:
153x/153 = 910/153
Simplify:
x = 910/153
2(-2,0 1, 3) that’s the answer I’m just trying to get some points I don’t know either
Answer:
5y
Step-by-step explanation:
First find all the factors of 15y^3 and then all the factors of -20y
15y^3 = 3 , 5 , y, y, y
-20y = 2 , 4, 5, 10, y
The GCF is 5 and y. We choose 5 because it is the greatest number and common in both sets. We also choose one y because it is common in both sets and one y is the greatest common y.
Answer = 5y
You can also do this by using the prime factorization method.
Answer:
68.0°
Step-by-step explanation:
The tangent function relates the sides of a right triangle to the angle:
Tan = Opposite/Adjacent
The mast is opposite the angle of elevation, and the shadow is adjacent, so you have ...
tan(angle) = (42 ft)/(17 ft)
The inverse tangent function is used to find the angle whose tangent is a particular value.
angle = arctan(42/17) ≈ 67.964°
The angle of elevation is about 68.0°.
Answer:
Option C, 262 cm^3
Step-by-step explanation:
<u>Step 1: Substitute 5 for radius and 10 for height</u>
V = 1/3 * pi * r^2 * h
V = 1/3 * pi * (5)^2 * (10)
V = 1/3 * pi * 25 * 10
V = 250pi/3
V = 261.79
Answer: Option C, 262 cm^3
