You are planning on using circles to compare the populations of California 37,691,000, Texas 25,675,000, and New York 19,465,000

kati45 [8]

The circle for New York:
r = 5 cm, Area : A = r² π = 25 π cm²
New York: 19,465,000
California: 37,691,000
Texas: 25,675,000.
-----------------------------------
California: 37,691,000 : 19,465,000 = 1.93635 N Y
1.93635 x 25 π = 48.4 π ⇒ r = 6.957 ≈ 7.0 cm
Texas : 25,675,000 : 19,465,000 = 1.319 N Y
1.319 x 25 π = 32.975 π ⇒ r = 5.742 ≈ 5.7 cm

HELP SOMEONE PLEASE HELP

romanna [79]

Answer:

Step-by-step explanation:

Evaluate the numerator/ denominator using order of operations

numerator = 16 + 2(4 × 2)

using the order parenthesis, multiplication followed by addition

= 16 + 2(8) ← evaluating parenthesis

= 16 + 2 × 8

= 16 + 16 ← performing multiplication

= 32 ← addition

denominator = 8 + 2³

using the order exponents then addition

= 8 + 8 ← evaluating exponent

= 16 ← addition

Hence

$\frac{numerator}{denominator}$ = $\frac{32}{16}$ = 2 → B

A train travels from station A to C having distance of 285 miles in 6 hours. During the journey, it reaches intermediate station

Nesterboy [21]

Answer:

Distance between B and C = $3\times 55=165miles$

Step-by-step explanation:

Let the time taken to reach from station A to B be x hr

Let the time taken to reach from station B to C be y hr

Given total time from station A to C be 6 hr

∴ x + y = 6

⇒ y = 6 - x → (1)

Also total distance given is 285 miles

As $Distance=Speed\times Time$

∴ distance travelled between station A and B

= $40\times xmiles$

distance travelled between station B and station C

= $55\times ymiles$

So, 40x + 55y = 285

⇒ 40x + 55(6 -x) = 285 (From 1)

=> 40x + 330 - 55x = 285

=> -15x = 285 - 330

=> -15x = -45 ⇒ x=3

gives y = 6-3 = 3 hours

Distance between B and C = $3\times 55=165miles$
