Answer:

7/22

Step-by-step explanation:

Step 1: Define/explain.

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: Solve.

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22

22 is the LCM.

Now, we change the fractions to where they both have denominators of 22.

**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**

$9/11*2/2=18/22$

$1/2*11/11=11/22$

Now, subtract as normal.

$18/22-11/22=7/22$

$7/22 (simplified).$

Step 3: Conclude.

Therefore, 9/11 - 1/2 = 7/22.

340 students went to the first school dance, the last school dance 306 students attended. What is the percent of change between

Fofino [41]

Answer:

10.59%

Step-by-step explanation:

percentage of change is given by

{(old number - new number)/old number} * 100

_________________________

given

no. of student went to the first school dance = 340

no. of student went to the last school dance = 306

Percentage of change between two dance

= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100

= (340 - 306)/340 *100

= (36/340 )*100 = 10.59%

The percent of change between the two dances 10.59%.

This Question: 1 pt

Feliz [49]

Answer:

The new salary of that person (for the period of a year) would be $\$ 16,\!275$ .

Step-by-step explanation:

Start by considering: what is the exact value (in dollars) of that " $5\%$ raise in salary"?

$5\%$ (five percent) is equal to $\displaystyle \frac{5}{100}$ .

To find the value of $5\%$ of $\$15,\!500$ , simply multiply $\$15,\!500$ by $5\%$ :

$\begin{aligned}&5\% \times \$15,\!500\\ &= \frac{5}{100} \times \$15,\!500 \\ &= 5\times \$155 = \$775 \end{aligned}$ .

Add that to the original (one-year) salary of this person to find the new one-year salary:

$\$15,\!500 + \$775 = \$16,\!275$ .

Madeline is standing 2x−4 feet from the base of a tree. The height of the tree is 5x+6 feet. Find the equation that shows the st

klemol [59]

Answer:

Required equation is $\sqrt{(2x-4)^2+(5x+6)^2}$ .

Step-by-step explanation:

Given,

Height of the tree=5x+6

Distance from feet of the tree=2x-4

To find straight distance from feet of Madeline to top of the tree.

Let the tree as y-axis and distance from base along x-axis. Then the distence of straight line from foot of Madeline to top is become the hypotenuse of the triangle. Thus if we let,

Distance from feet of Madeline to top of tree= p, then, according to law of finding third side of a triangle we get,

$p^2=(\textit{distance from base})^2+(\textit{height of tree})^2$

$\therefore p=\sqrt{(2x-4)^2+(5x+6)^2}$

Hence the result.

What is the equation of this line?

dezoksy [38]

Answer:

A. y = 2x - 3

Explaination:

It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.
