Answer:
<u>The three true options are B, C and E.</u>
Step-by-step explanation:
Let's simplify the expression that represent the score of Javier in a game of mini-golf:
3x + x + 5 – 2x
2x + 5
Which statements are true about the parts of the simplified expression? Select three options.
A. The constant is 2.
It's false. The constant is 5.
B. The coefficient is 2.
It's true. The coefficient of x is 2.
C. The constant is 5.
It's true.
D. The coefficient is 5.
It's false. 5 is the constant and the coefficient of x is 2.
E. There are two terms.
It's true. The two terms are 2x and 5.
<u>The three true options are B, C and E.</u>
The formula for surface area of a sphere is A=4*PI*r^2
Using that formula and the known surface are we can find the radius. We can then use that to find the volume.
500 = 4*PI*r^2
Divide both sides by 4:
500/4 = PI *r^2
125 = PI *r^2
Divide both sides by PI
125/PI = r^2
39.79 = r^2
r = SQRT(39.79)
r = 6.3 cm
Now we can find volume using V=4/3*PI*r^3
V = 4/3 *PI *6.3^3
V= 1051.3
The answer is C
Answer:
75000
Step-by-step explanation:
We can use ratios to solve. Put the scale length over the real length
1 15
------------ = ----------------
5000 x
Using cross products
1x = 15*5000
x =75000
Solve the problem yourself first, to see if Pedro made any mistakes.
4/7 x 8/5
4x8 = 32
7x5 = 35
32/35 is the answer.
Pedro made his error in step 2, he cross multiplied instead of multiplying the numerators, and then the denominators.
8,500,000
Round the number 4 to 5 because the number 7 is behind it.
