Answer:
64 carnations and 16 roses.
Step-by-step explanation:
The events committee buys 80 flowers
The flowers are a combination of carnations and roses.
Each carnation costs $0.50 and each rose costs $2.50
The committee spends a total of $72
<u>Solution:</u>
<u />
Let there be (c) carnations and (r) roses.
So,
c + r = 80 flowers
and $0.50c + $2.50 = $72
This forms a simultaneous equation:
c + r = 80 ... (i)
0.5c + 2.5r = 72 ... (ii)
Multiplying equation (i) by 0.5 and equation (ii) by 1 gives;
0.5c + 0.5r = 40 ... (i)
0.5c + 2.5r = 72 ... (ii)
Subtracting (i) from (ii) gives;
0c + 2r = 32
2r = 32
r = 32 ÷ 2 = 16
Therefore, there are 16 roses
and 80 - 16 = 64 carnations

The required proportion of the blue paint is 18 liters.
Given that,
The ratio of yellow and blue colors is 2:3
The proportion of the yellow color is 12 liters.
The proportion of blue color is to be determined.
<h3>What is the Ratio?</h3>
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Let the proportion of the blue color is x,
Now, the ratio can be given as
12 / x = 2 / 3
x = 12 * 3 / 2
x = 18
Thus, the required proportion of the blue paint is 18 liters.

(b) 
So, it becomes,
(c) 
As we know that
So, it becomes,
(d) 
Hence, a) 15625, b) 0.2, c) 625, d) 0.008.
Answer:
<h2>
3.6° and 86.4°</h2>
Step-by-step explanation:
24x - measure of an angle
x - the measure of a complementary angle
Complementary angles adds to 90°
x + 24x = 90°
25x = 90°
x = 90°÷25
x = 3.6°
24x = 24·3.6° = 86.4°
