Answer:

20/9

Step-by-step explanation:

2/3 ÷ 3/10 = 2/3 × 10/3....in which this would give us...(20/9)

To prove if its true...we then go into the second statement,

(20/9) × 3/10 = 60/90...in which if you divide both the numerator and the denominator of our answer (60/90) by 30....it would give us (2/3)..Hence shown

S1548.

Step-by-step explanation:

1-7% =- 0.017 and 5.3% - 0.053.

Kevin : After 1 year he has 43,000 * 0.017 = S731.

Greg: After 1 year he has 43,000 * 0.053 = S2279

Difference = 2279 - 731 = S1548.

A braid was bought to put around a blanket that measures 23 inches by 24 inches. At $0.60 per yard how much was paid for the bra

mojhsa [17]

To do this you need 94 inches of braid.

94 inches = ? yards

1 inch = 0.0277778 yard

94 × 0.0277778 = 2.6111132.

Since you can only pay for a full yard you would buy 3 yards which would cost:-

$0.60 × 3 = $1.80.

So for this you would need 3 yards which would cost $1.80.

Hope I helped:P

Kim is watching a satellite launch from an observation spot 6 miles away. Find the angle of elevation from Kim to the satellite,

Allisa [31]

Answer:

Angle of elevation from Kim to the satellite launch = 6.654°

Step-by-step explanation:

The distance from Kim to the satellite launch

= 6 miles

Height of the satellite launch

= 0.7 miles

Angle of elevation from Kim to the satellite launch = b

Tan b = height of satellite/distance from Kim

Tan b= 0.7/6

Tan b= 0.1166667

b = tan^-1 (0.1166667)

b= 6.654°

Angle of elevation from Kim to the satellite launch = 6.654°
