the highest batting average is of Ed's and that is 0.350 .

<u>Step-by-step explanation:</u>

Here we have , Make, Dan, Ed, and summer played together on a baseball team. Mike’s batting average was 0.349, dan’s was 0.2, Ed’s was 0.35, and sy’swas 0.299. We need to find Who had the highest batting average . Let's find out :

According to question we have following parameters as :

$Mike = 0.349\\Dan's=0.200\\Ed's=0.350\\Sy'swas=0.299$

Arranging these data from decreasing to increasing order we get :

⇒ $0.200$

⇒ $(Dan's)0.200$

Therefore , the highest batting average is of Ed's and that is 0.350 .

Which pair shows equivalent expressions? 2 x + 10 = negative 2 (x minus 5) Negative 2 (x + 5) = 2 x minus 10 Negative 2 x minus

stellarik [79]

Answer:

C. –2x – 10 = –2(x + 5)

Step-by-step explanation:

Clearer choices:

2x + 10 = –2(x – 5)

–2(x + 5) = 2x – 10

–2x – 10 = –2(x + 5)

–2(x – 5) = –2x – 10

All choices have either:

–2(x – 5) for A and D

or –2(x + 5) for B and C

Simplify these expressions by <u>expanding</u> with the distributive property. Multiply the outside term "–2" with each term inside the brackets.

–2(x – 5)

= (–2*x) – (–2*5) Multiply each term by the coefficient

= –2x – (–10) Simplify the double negative to a positive

= –2x + 10 Expanded expression

This is not the same answer in A and D. They are not correct.

–2(x + 5)

= (–2*x) + (–2*5) Multiply each term by the coefficient

= –2x + (–10) Adding a negative is the same as subtraction

= –2x – 10 Expanded expression

This is the same answer for <u>option C</u>.

Therefore "C" is the answer.

Sphere A has a diameter of 2 and is dilated by a scale factor of 3 to create sphere B. What is the ratio of the volume of sphere

krok68 [10]

Answer:

1:27 (D)

Step-by-step explanation:

Given:

Sphere A has a diameter of 2

Sphere A is dilated to create sphere B

Scale factor = 3

Volume of a sphere = 4/3 πr³

Radius = r = diameter/2 = 2/2

r = 1

Volume of sphere A = 4/3 ×π(1)³

Volume of sphere A = 4/3 × π

Volume of sphere B = 4/3 πR³

Since the diameter was dilated, the diameter of B = diameter of A × scale factor

diameter of B = 2×3 = 6

Radius of B = R = diameter/2 = 3

Volume of sphere B = 4/3 × π(3)³

Volume of sphere B = (4/3)(27)π

Ratio of the volume of sphere A to volume of sphere B

= [4/3 ×π]: [(4/3)(27)π]

= (4π/3)/[(4π/3)×27] = 1/27

= 1:27
