Option B

Step-by-step explanation:

A) 30w + 35 does not equal 65, because we are not given that w=1

B) 5(6w + 7) equals 30w + 35, so it is correct

C) 30w + 35 does not equal 65, because we are not given that w=1

D) 6w + 7 is (30w + 35)/5, which is not equal to (30w + 35)

E) N/A

Janice has three times as many dimes as nickels. If the total value of the money is $9.10, how many of each types of coin does s

ICE Princess25 [194]

X= number of nickels
3x= number of dimes

Each nickel is $0.05 and each dime is $0.10. Multiply each coins monetary value by the quantity of each. Add them equal to the total $9.10.

(0.05 * x) + (0.10 * 3x)= 9.10
multiply inside parentheses

0.05x + 0.3x= 9.10
add

0.35x= 9.10
divide both sides by 0.35x

x= 26 nickels

DIMES
3x= 3(26)= 78 dimes

CHECK:
(26 nickels * 0.05) + (78 dimes * 0.10)= 9.10
$1.30 + $7.80= $9.10
$9.10= $9.10

ANSWER: There are 26 nickels and 78 dimes.

Hope this helps! :)

A strip mall in Dallas has store space in several different sizes. There are eight 300-square-foot stores, one 800-square-foot s

Vesna [10]

Answer:

Part 1: "What is the ratio of vacant space to occupied space?" $\frac{6}{35}$

Part 2: "What percent of the space is occupied?" 85.37%

Step-by-step explanation:

1st part:

Total square foot = (8*300) + (1*800) + (1*900) = 4100 sq. feet

Vacant Space = 2*300=600

Occupied Space = 4100 - 600 = 3500

Thus ratio of vacant space to occupied space = $\frac{600}{3500}=\frac{6}{35}$

2nd part:

To find % of occupied space, we need to divide occupied space (in sq ft.) by the total square feet and then multiply by 100 (since we want the percentage):

$\frac{3500}{4100}=0.8537=85.37$

Occupied space is 85.37%

Step-by-step explanation:

Okay. Are you taking calc? Dv/dt =d/dt(L(t)^3)=d/dt[(sqrt(14)+2t)^3]= 6(Sqrt(14)+2t)^2)=44. We defined t=0 to be time at which length is sqrt(14). Does that work?
