Mathematics
1 answer:
WINSTONCH [101]3 years ago
7 0

Answer:

\frac{9}{16}

Step-by-step explanation:

17 = 1 + 9n

Subtract 1 from both sides

17 - 1 = 1 - 1 + 9n

16 = 9n

Divide through by 9

\frac{16}{9}  =  \frac{9n}{9}

n =  \frac{16}{9}

The inverse of the answer is

\frac{9}{16}

400 grams = 480 ml<br> so,<br> 180 grams = ?
Viefleur [7K]

Answer: 216 ml

Step-by-step explanation:

400 grams = 480 ml

180 grams = ?

Since the value of 180 grams in milliliters is unknown, let the unknown be Z

Thus, 400 grams = 480 ml

180 grams = Z

To get the value of Z, cross multiply

Then, Z x 400 grams = 480ml x 180 grams

400Z = 86400

Divide both sides by 400

400Z/400 = 86400/400

Z = 216

Thus, 180 grams is equal to 216 milliliters.

Nadusha1986 [10]
To get the distance DC we proceed as follows:
AB-CD
=11-3
=8 
BC=15
hence using Pythagorean theorem
c²=a²+b²
c=DC
a=BC
b=8
thus
c²=15²+8²
c²=225+64
c²=289
thus
c=√289
c=17 units

Answer: B. 17 units

A principal of $2600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 8 years?
almond37 [142]
To add 7.5% to a number you simply multiply the number by 1.075. To compound that amount year after year, you raise 1.075 to an exponent that corresponds to the number of years.  2600*(1.075^8)=<span>4637.04234646</span>

(i) 14×25 = 350 g fertiliser would be needed for 14 m^2 land

(ii) 450÷25 = 18 m^2 land could be fertilised with 450 g fertiliser
