Carlos wants to put 720 of his blocks in his toy box. A small set has 10 blocks and a large set has 100 blocks. How can you writ
Natasha_Volkova [10]

Carlos can put the blocks in this three ways:

(i) 32 large blocks and 4 small blocks.

(ii) 22 large blocks and 5 small blocks.

(iii) 12 large blocks and 6 small blocks.

The total quantity of blocks equals the number of blocks stored in the sets of blocks. Based on the information given, we derive the following algebraic expression:

10\cdot m + 100\cdot n = 720, \forall\,m,n\in \mathbb{N_{O}} (1)

Where:

  • m - Quantity of small blocks.
  • n - Quantity of large blocks.

Now we can clear n in terms of m:

100\cdot n = 720 -10\cdot m

n = 7.2-0.1\cdot m (2)

From (2) we get the following combination of sets:

1) m = 12, n= 6

2) m = 22, n = 5

3) m = 32, n = 4

Carlos can put the blocks in this three ways:

(i) 32 large blocks and 4 small blocks.

(ii) 22 large blocks and 5 small blocks.

(iii) 12 large blocks and 6 small blocks.

A number from 1-100 is randomly selected. What is the probability that it is a perfect square, given that it is an odd number?
coldgirl [10]
Events:
1 ≤ n ≤ 100
A=x is a perfect square, i.e. x=n^2
B=x is odd, i.e. n is odd
P(A|B)
=P(A∩B)/P(B)   by definition of conditional probability
(reads Probability that the number is a perfect square given that it is odd)

Since there are 10 perfect squares between 1 to 100 (1,4,9,16,25,36,49,64,81,100), out of which 5 are odd {1,9,25,49,81)
So P(A∩B)=5/100
P(B)=probability of odd x  {1,3,5,7,.....95,97,99}
= 50/100=1/2
Therefore 
P(A|B)=(5/100)/(1/2)=1/10

What is the equation of the line that passes through the point (-2,-1) and has a slope of 5/2
Darya [45]

Answer:

y = (5/2)x + 4

Step-by-step explanation:

We'll look for an equation in the format y = mx + b, where mn is the slope and b the y-intercept (the value of y when x = 0).

y = mx + b

m is (5/2)

y = (5/2)x + b

We need a value of b that will force the line through point (-2,-1).  Enter the point (-2,-1) in the equation and solve for b:

y = (5/2)x + b

-1 = (5/2)(-2) + b

-1 = -5 + b

b = 4

<u>The equation is y = (5/2)x + 4</u>
