How do you solve the equation k/90-1/9=1/90

Mariulka [41]

Answer:

k = 11

Step-by-step explanation:

k/90 - 1/9 = 1/90

k/90 = 1/90 + 1/9

k/90 = 1 + 10/90

k/90 = 11/90

k = 11/90 / 90

k = 11/90 * 90

k = 11

Allison can row a boat 1 miles upstream (against the current) in 24 minutes. She can row the same distance downstream in 13 minu

prohojiy [21]

Answer: The speed of rowing is 3.56 miles per hour and speed of current is 1.06 miles per hour.

Step-by-step explanation:

Since we have given that

Let the speed of boat in still water be 'x'.

Let the speed of current be 'y'.

Distance = 1 mile

For Upstream, speed would be

$x-y=\dfrac{1}{24}\times 60=2.5$

For downstream, speed would be

$x+y=\dfrac{1}{13}\times 60\\\\x+y=4.615$

By graphing method we get that

x = 3.558 miles/hr

and y = 1.058 miles/hr

Hence, the speed of rowing is 3.56 miles per hour and speed of current is 1.06 miles per hour.

Which expressions simplify to 0? Check all that apply. 8g – 8g, (–2g) – 2g, 5g + (–5g), One-half g + one-half, g Negative two-th

victus00 [196]

We have been given 4 expressions. We are asked to choose the expressions, which simplifies to 0.

Let us check our given choices one by one.

1. $8g-8g$

$8(g-g)$

$8(0)=0$

When we will subtract 8g from 8g, we will get 0. Therefore, expression $8g-8g$ simplifies to 0.

2. $(-2g)-2g$

Let us remove parenthesis.

$-2g-2g$

Upon combining like terms, we will get:

$-4g$

Since $(-2g)-2g$ simplifies to $-4g$ , therefore, expression $-2g-2g$ is not a correct choice.

3. $5g+(-5g)$

Let us remove parenthesis.

$5g-5g$

Upon combining terms, we will get:

$5g-5g=0$

Since $5g+(-5g)$ simplifies to 0, therefore, expression $5g+(-5g)$ is a correct choice.

4. $\frac{1}{2}g+\frac{1}{2}g-\frac{2}{3}g+\frac{2}{3}g$

Let us combine the terms as:

$\frac{1+1}{2}g-\frac{2}{3}g+\frac{2}{3}g$

$\frac{2}{2}g-\frac{2}{3}g+\frac{2}{3}g$

$g-g(-\frac{2}{3}+\frac{2}{3})$

$g-g(0)$

$g-(0)=g$

Since $\frac{1}{2}g+\frac{1}{2}g-\frac{2}{3}g+\frac{2}{3}g$ simplifies to $g$ , therefore, expression $\frac{1}{2}g+\frac{1}{2}g-\frac{2}{3}g+\frac{2}{3}g$ is not a correct choice.

juin [17]

Answer:

h=52 and h is the shortest

Step-by-step explanation:

180-f-g=h step 1. -f from 180

180-60=120 step 2. -g from 120

120-68= 52

h=52 degrees
