Answer:

a is equal to 60

Step-by-step explanation:

From the question,

64 = 4(a-44)

expanding the bracket;

64 = 4a - 176

64 + 176 = 4a

240 = 4a

Divide by 4;

a = 240/4

a = 60

60 is greater than 44.

Answer:

a) 1.4 * 10^5 = 1.4 * 10 * 10 * 10 * 10 * 10= 140,000 km

b) Mars has the smallest diameter (6,800 km). A helpful tip is to look at the exponents of the base; Mars' exponent is 3 which is the least.

c) Diameter of Saturn - Diameter of Neptune

= (1.2 * 10^5) - (5.0 * 10^4)

= (120,000) - (50,000)

= 70,000 km

The difference between the diameter of Saturn and the diameter of Neptune is 70,000 km.

Chase goes out to lunch. The bill, before tax and tip, was $11.90. A sales tax of 9% was added on. Chase tipped 17% on the amoun

WINSTONCH [101]

Answer:

$15.17

Step-by-step explanation:

First we calculate the value for the sales tax:

$11.90 \times \frac{9}{100 } = 1.07$

we then add the value for the sales tax ($1.07) to the initial bill:

$11.90 + 1.07 = 12.97$

We were instructed to calculate the tip after the sales tax was added so:

$12.97 \times \frac{17}{100} = 2.20$

after we will add the value for the tip to the value that we have for the bill ( this is the new value that includes the sales tax) to find the total cost:

$12.97+ 2.20 = 15.17$

Therefore the total cost for his mean is $15.17
