Answer:

You got the answer right.

The first question BC is 5 cm.

In the second question, we gotta find the hypotenuse.

In a 45 45 90 triangle, the hypotenuse will have a length of $x\sqrt{2}$ , therefore, the side AC is equal to $10\sqrt{2}$ .

A restaurant offers diet soda and regular soda. In one day they sold 14 diet sodas. If the ratio of diet sodas sold to regular s

finlep [7]

Answer: 26 sodas.

Step-by-step explanation:

Let be "x" the number of regular sodas that were sold in that day.

You know that the the ratio of diet sodas sold to regular sodas sold was:

$7 : 6$

This ratio can also be written as a fraction:

$\frac{7}{6}$

Knowing that in that day they sold 14 diet sodas, you can write the following proportion:

$\frac{7}{6}=\frac{14}{x}$

Now solve for "x":

$(x)(\frac{7}{6})=14\\\\x=(14)(\frac{6}{7})\\\\x=12$

Then the total number of sodas sold that day is:

$Total=14\ sodas+12\ sodas=26\ sodas$

If log10(x^{2}y^{3})=7 and log10 (x/y)=1 , then x=__ and y= __

yuradex [85]

Answer:

$x=100$

$y=10$

Step-by-step explanation:

we are given

$log_1_0(\frac{x}{y})=1$

Firstly, we will get rid of log

so, we will take exponent over 10 on both sides

$10^{log_1_0(\frac{x}{y})}=10^{1}$

now, we can simplify it

$\frac{x}{y}=10$

now, we can solve for x

$x=10y$

we are given

$log_1_0(x^2y^3)=7$

Firstly, we will get rid of log

so, we will take exponent of 10 on both sides

$10^{log_1_0(x^2y^3)}=10^7$

$x^2y^3=10^7$

now, we can plug back x from first equation

$(10y)^2y^3=10^7$

now, we can solve for y

$100y^5=10000000$

$\frac{100y^5}{100}=\frac{10000000}{100}$

$y^5=100000$

now, we can take radical 5

$y=\sqrt[5]{100000}$

$y=10$

now, we can find x

$x=10\times 10$

$x=100$

So, solution is

$x=100$

$y=10$
