On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
Answer: 2,1 4,1 5,7 and yeah im not sure what else to put
poggers hehe
Answer:
C: 50%
Step-by-step explanation:
There are 2 even numbers and 2 odd numbers on the spinner.
Therefore, the probabilty of getting an odd number is 2/4 = 1/2 = 0.5 = 0.5 x 100 = 50%
Answer:
15: Yes, no, yes, yes, no; 16A: C = ($0.29)X + ($1.45)Y + ($2.50)Z; 16B: Yes
Step-by-step explanation:
For question 15: We need to multiply the widths and lengths given to see if they equal the area we are trying to achieve. Therefore, some of them work, and some do not.
For question 16:
Part A: We'll set a variable for the number of each supply she can buy. Pencils will be represented by X, pens by Y and Notebooks by Z, and we'll represent total cost by C. The total cost will therefore be represented by C = ($0.29)X + ($1.45)Y + ($2.50)Z.
Part B: We'll plug the numbers of items she wants to buy into our formula and see if it comes out to less than $20. So in this case C = ($0.29)(3) + ($1.45)(4) + ($2.50)(2). Therefore, C = $11.67, which is less than $20, so she can afford her school supplies.
Answer:
If you made $33 in 8 hours, then you should divide 8 into 33 to see how much you make per hour. 8÷33= (explaining how to get answer) can 8 go into 3? No. put a zero on top of the first three. Now can 8 go into 33? yes, 4 times, 4×8= 32, so we have 1 left over. add 2 decimals to the number so that it is $33.00, (still that same number just with zeros on the end). So far the answer is $04.??. How many times can 8 go into 10? 1 time with 2 left over, so write the one on top of the .0! Now with 2 left over we have to see how many times 8 can go into 20, 8×2= 16 16+8=24, so it can only go in 2 times without going over 20. Now that we have rounded it up to 2 decimals we don't have to keep going and your answer is
$4.12 times that by 5 and you will get the final answer.
4.12
× 5
20.60
Hope I explained I okay!
