Answer:
Length of base (a) = 5 units
Total Surface Area of Pyramid (T.S.A.) = ?
Now,
T.S.A. = Area of four triangles + Area of base
= ≈
Answer:
its at (0,0)
Step-by-step explanation:
i think
It forms an acute angle.
The obtuse angle is greater than 90 degrees but less than180 degrees. So if a bisector is introduced, the resulting angle is acute. An acute is less than 90 degrees.
Answer:
He had $36 in the beginning
Step-by-step explanation:
We are asked to calculate how much John has after making some series of purchases. Let’s proceed.
Now, let the initial amount of money John had be $X. Let’s keep this
He initially spends 2/3 at a bookstore, the fraction unspent is 1/3. Since x is our figure, the amount unspent is $x/3
Now, he spent 1/3 of this at a craft store. This means he didn’t spend 2/3 of this and it corresponds to $8.
This mathematically means:
2/3 * $x/3 = $8
2x/9 = $8
2x = $72
x = $72/2 = $36
Answer:
1) True
2) True
3) False
4) True
Step-by-step explanation:
1) You can compare irrational numbers using rational approximations
The above statement is true as given two irrational numbers which can be expressed in decimal format, by rounding up the numbers to a certain number of decimal places, the values of the irrational numbers will be different
2) Square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol
The above statement is true as the the values of the numbers under the radical symbol are directly proportional to the square root
3) You cannot compare the value of rational and irrational numbers
The above statement is false because the value of an irrational number can be found between two rational numbers. Therefore, the value of an irrational number is higher than the rational number that precedes it on the left of a number line
4) The closer the numbers being compared, the more decimal places you need to use
The above statement is true as a higher level of detailed value of the numbers being compared will be required given the closeness in value of the numbers being compared.
