A proportion is an equation that states that two ratios are equal
Answer:
-11.7
Step-by-step explanation:
3.3+5(-7 + 4)
we apply distributive property
3.3+5*(-7) + 5*(4)
we know:
+ * - = -
+ * + = +
so we have:
3.3 -35 + 20
3.3 - 15
-11.7
Answer:
There are ways for quickly multiply out a binomial that's being raised by an exponent. Like
(a + b)0 = 1
(a + b)1 = a + b
(a + b)2 = a2 + 2ab + b2
(a + b)3 = (a + b)(a + b)2 = (a + b)(a2 + 2ab + b2) = a3 + 3a2b + 3ab2 + b3
and so on and so on
but there was this mathematician named Blaise Pascal and he found a numerical pattern, called Pascal's Triangle, for quickly expanding a binomial like the ones from earlier. It looks like this
1 1
2 1 2 1
3 1 3 3 1
4 1 4 6 4 1
5 1 5 10 10 5 1
Pascal's Triangle gives us the coefficients for an expanded binomial of the form (a + b)n, where n is the row of the triangle.
Hope this helps!
Answer:
10
Step-by-step explanation:
The 7 in 27,459 is in the <em>thousands</em> place.
The 7 in 40,735 is in the <em>hundreds</em> place.
Any digit in the thousands place has 10 times the value of the same digit in the hundreds place. (The multiplier is 1000, instead of 100.)
_____
In the base-10 number system, each digit location has 10 times the value of the location to its right. The value is determined by the place the digit occupies in the number. That is why it is called a place-value number system.
3.15. Just find the unit rate which is 1.5 and multiply that by 3
