Answer:

K=30

Step-by-step explanation:

rewrite \: the \: equation \: as \:  \frac{k}{9}  =  \frac{10}{3}

\frac{k}{9}  =  \frac{10}{3}

multiply \: both \: sides \: of \: the \: equation \:  \\ by \: 9.

9. \frac{k}{9}  = 9. \frac{10}{3}

simplify \: both \: sides \: of \: the \: equation.

cancel \: the \: common \: factor \: of \: 9.

cancel \: the \: common \: factor.

9. \frac{k}{9}  = 9. \frac{10}{3}

rewrite \: the \: expression.

k = 9. \frac{10}{3}

cancel \: the \: common \: factor \: of \: 3.

factor \: 3 \: out \: of \: 9.

k=3(3)⋅ \frac{10}{3}

cancel \: the \: common \: factor.

k=3⋅3⋅ \frac{10}{3}

rewrite \: the \: expression.

k=3⋅10

multiply \: 3 \: by \: 10.

k = 30

A store sells both cold and hot beverages. Cold beverages, c, cost $1.50, while hot beverages, h, cost $2.00. On Saturday, drink
ra1l [238]

Answer:

The number of hot beverages sold were 45 and the number of cold beverages sold were 180.

Step-by-step explanation:

Let the number of cold  beverages sold be c

And the number of hot beverages sold be h

According to the question:

c=4\times h...

$ 1.5\times c + 2\times h = Sale of any day

Part1:

For Saturday.

The sale is of $360

then

$ 1.5 \times c + $ 2 \times h =$ 360

Part 2:

Following the method of substitution.

And plugging the values of c=4\times h...in equation where the sales of Saturday is given.

1.5\times c + 2\times h =360

1.5\times 4\times h + 2 \times h =360

6\times h + 2\times h= 360

8\times h=360

Dividing both sides with 8.

h=\frac{360}{8}

h=45

Inserting h=45 in c=4 \times h...

we have c=4\times 45 = 180

So the number of hot beverages sold were 45 and the number of cold beverages sold were 180.

Find the length of the second leg of the triangle round to the nearest hundredth
horsena [70]

Answer:

\displaystyle \frac{3\sqrt{230}}{5}

Step-by-step explanation:

Use the Pythagorean Theorem:

\displaystyle a^2 + b^2 = c^2 \\ \\ 9,7^2 + b^2 = 13,3^2; \sqrt{82,8} = \sqrt{b^2} \\ \\ \frac{3\sqrt{230}}{5}\:[or\:9,0994505329...] = b

So, you have this:

\displaystyle 9,1 ≈ b

The equation x^2−8x−5=0 can be transformed into the equation (x−p)^2=q, where p and q are real numbers. What is the value of q?
Setler79 [48]

Answer:

x = 5

  or

x = 3

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -8x  its coefficient is  -8 .

The last term, "the constant", is  +15

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   -8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8
