65 over 100 of what number is 780

skad [1K]

Step-by-step explanation:

$\frac{65}{100} \times x = 780 \\ \\ \therefore \: x = 780 \times \frac{100}{65} \\ \\ \therefore \: x = 60 \times \frac{100}{5} \\ \\ \therefore \: x = 60 \times 20 \\ \\ \therefore \: x = 1200 \\$

Hence, 65 over 100 of 1200 is 780.

Suppose that a nonnegative integer solution to the equation u + v + w + x + y = 12, thought of as a 5-tuple (u,v,w,x,y) is chose

son4ous [18]

Answer:0.2

Step-by-step explanation:

Given

$u+v+w+x+y=12$

total solution for $u+v+w+x+y =12$ is given by $^{n+r-1}C_{r-1}$

here $n=12\ r=5$

i.e. $^{12+5-1}C_{5-1}=^{16}C_4$

For $u=1$

$1+v+w+x+y=12$

$v+w+x+y=11$

no of solutions for this equation is

$^{11+4-1}C_{4-1}=^{14}C_3$

if one solution is chosen at random Probability that u=1

$=\frac{^{14}C_3}{^{16}C_4}$

$=\frac{364}{1820}=0.2$

⦁ A local pizzeria sold 75 pizzas yesterday.

rodikova [14]

Answer:

a. 90 pizzas

b. 12% decrease

Step-by-step explanation:

To receive a bonus, there must be 20% increase in the number of pizzas

Thus;

20% of 75 = 20/100 * 75 = 1500/100 = 15

So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90

So now, we have 66 pizza sold today;

We can see that there was a decrease from 75

Percentage decrease will be;

(new value - old value)old value * 100%

= (66-75)/75 * 100%

= -9/75 * 100%

= -0.12 * 100% = -12%

This shows a 12% decrease
