First find the length of the longest leg
x^2 = 13^2 - 5^2 ( by the Pythagoras theorem)
x^2 = 144
x = 12
Area of the traingle = 1/2 * base * height
= 1/2 * 5 * 12
= 30 units^2
Set y equal to 25 because this is the amount of money Aisha wants to save. This gives you 25 = 50-1.99x. Now we can solve for x, which is the variable. First, subtract 50 from both sides so that you can get the variable, x, by itself. After subtracting 50 from both sides, you are left with -25 = -1.99x . If it is easier for you, you can put the numbers on opposite sides so it reads -1.99x = -25 . Now divide both sides by -1.99 so that x is by itself. So -1.99x ÷-1.99 = 1x which is equal to just x and -25÷-1.99 = about 12.56, which is a decimal. (Remember that when you divide a negative number by a negative number, it becomes a positive number) Finally we have x = 12.56 (or 1x = 12.56) with 12.56 being equal to the number of songs Aisha can buy if she also wants to save money in her bank account. However, nobody can buy only .56 or part of a song. Round down to the nearest whole number, which is 12. This is how many songs she can buy and it makes sense because it is 12 entire songs, not 12 and just the chorus of a song. If you want to check, you can plug in 12 for x and she shouod have a little more than $25 in her bank account. So Aisha can buy 12 songs is she wants to save $25. I hope this helped :)
IQR = Q3 - Q1
Q1 is where the box starts and Q3 is where the box ends.
So in this case:
Q1 = 25
Q3 = 33
Subtract:
33 - 25 = 8
So the IQR is 8.
Answer:
Each Tomskian build 6 igloos per week.
Each Kyzylian build 5 igloos per week.
Step-by-step explanation:
Unit rate refers to how much the buyer paid per unit. Let’s do the math:
$2.52 for 4.5 pounds of potatoes
Divide $2.52 by 4.5
The shopper paid 56 cents per pound of potatoes.
Now $7.75 spent for 2.5 pounds of broccoli.
Divide $7.75 by 2.5.
The shopper paid $3.10 for each pound of broccoli.
Last $2.45 for 2.5 pounds of pears.
The shopper will spend 98 cents per pounds of pears.
