Answer:
acute: 7, 9
right: 8, 10
obtuse: 5, 6
Step-by-step explanation:
When you have a number of identical calculations to do, it is convenient to do them in a spreadsheet. You only need to enter the formula once and copy it as many times as needed.
The attachment shows the "sum of squares" calculation and comparison to the square of the longest side. When the sum is too small, the longest side is longer than needed for a right angle, so the triangle is obtuse. When the sum is too great, the longest side is too short for a right angle, so the triangle is acute.
We have skipped the tedious arithmetic and shown the results in the attached table.
Answer:
A. 17 1/2 . . . cubic feet
Step-by-step explanation:
The volume is the product of the length, width, and height. If your calculator doesn't deal with mixed numbers, it can be convenient to use one that does.
(4 ft)(2 1/2 ft)(1 3/4 ft) = 17 1/2 ft³
The volume of the box is 17 1/2 cubic feet.
____
You can also convert the numbers to decimal to use on your calculator:
4 × 2.5 × 1.75 = 17.500
Or convert them to improper fractions:
4 × 5/2 × 7/4 = 35/2 = 17 1/2
Answer:
A cube has 6 equal faces, 8 vertices, and 12 edges.
Step-by-step explanation:
My answer is self-explanatory.
Answer:
A
Step-by-step explanation:
To find the answer, convert the fractions so that they have the same denominator. 2/4 can be 3/6, since both of them are one half. 1/3 can be 2/6 since both are a third. 3/6 + 2/6 = 5/6.
Steps are simple:
1- Write the standards of conversion
2- Write the value you want to convert
3- Use cross multiplication to get the converted value
Examples:
i- Say we want to convert 890 cm to meters.
We know that 1 cm = 0.01 meters
Now, we will write the number we want to convert and use cross multiplication as follows:
1 cm = 0.01 meters
890 cm = ?? meters
converted value = (890*0.01) / 1 = 8.9 meters
ii- Say we want to convert 568 kg to grams.
We know that 1 kg = 1000 grams
Now, we will write the number we want to convert and use cross multiplication as follows:
1 kg = 1000 gram
568 kg = ?? grams
converted value = (568*1000) / 1 = 568000 grams
Hope this helps :)
