The time at which the lorry the time taken arrive at it destination is 12.20.
Given :
A lorry leave a factory on a journey of 195km at 08 45 , travelling at an average speed of 52 km/h.
here,
Distance = 195 km
Speed = 52 km/h
we know that ,
speed = distance / time
on cross muliplicating
speed * time = distance
time = distance / speed
substitute the values
time = 195 / 52
= 3.75 hours
destination time = 8.45 + 3.75
= 12.20
Therefore the time at which the lorry the time taken arrive at it destination is 12.20

A state government borrows $2,000,000 at simple annual interest. Some of the money is borrowed at 6%, some at 7.5%, and some at 8.5%. Use a system of linear equations to determine how much (in dollars) is borrowed at each rate given that the total annual interest is $137,000 and the amount borrowed at 7.5% is four times the amount borrowed at 8.5%. Solve the system of linear equations using matrices.
If the amount borrowed at 7.5% is four times the amount borrowed at 8.5%. The amount borrowed is: $200,000, $800,000, $1,000,000.
How to find the amount borrowed?Now let find the amount borrowed
Let X+Y+Z = 2000000
0.06X + 0.075Y + 0.085Z = 137000
Y = 4Z
Substituting Y=4Z into the first and second equations:
X + 5Z = 2000000
0.06X + 0.075(4Z) + 0.085Z = 137000
X = 2000000 - 5Z
0.06X + 0.385Z = 137000
0.06(2000000 - 5Z) + 0.385Z = 137000
120000 - 0.3Z + 0.385Z = 137000
0.085Z + 120000 = 137000
0.085Z = 17000
Divide both side by 0.085Z
Z= 17,000/0.085
Z = 200000
So,
Y = 4Z
Y = 800000
X= 200,000 + 800,000
X = 1000000
Hence,
Z = 200000
Y = 800000
X = 1000000
Therefore the amount borrowed is: $200,000, $800,000, $1,000,000.

Why doe the Ditributive property make it eaier to multiply a 2 digit number the a 1 digit number
Distributive property make it easier to multiply a 2 digit number t0 a 1 digit number because by using distributive property we can multiply the number place of the two digit number by one digit number and inlast we can add it , which makes the whole process easier.
According to Distributive property it helps to solve the complex problems easily either they are of 2 digit or many more . Distributive property multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
In other words, according to the distributive property, an expression of the form A (B+C) can be solved as A (B+ C) = AB + AC.
This property applies to subtraction as well.
A (B –C) = AB – AC

Which graph represents f of x equals square root of the quantity x plus 3 end quantity minus 2?
The graph that correctly represents the function f(x) = [√(x + 3)] - 2 is; Graph D
How to interpret the graph of the function?
We are given the function;
f(x) = [√(x + 3)] - 2
Remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:
x + 2 = 0
x = -2
Then the function starts at:
f(-2) = [√(-2 + 3)] - 2
f(-2) = 3
Then the graph should start at (-3, 2).
We can also identify another point by evaluating in x = 2.
f(2) = [√(2 + 3)] - 2
f(2) = -1
So the function also passes through (2, - 1).
Notice that the only graph that contains these two points is the last graph with x-intercept at 7.

What is rhombus ?
A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.
A parallelogram is a particular instance of a rhombus. The opposing sides and angles in a rhombus are parallel and equal. A rhombus also has equal-length sides on each side, and its diagonals meet at right angles to form its shape. The rhombus is also referred to as a diamond or rhombus.
A quadrilateral with four equal sides that has the shape of a diamond is called a rhombus. In everyday life, rhombus-shaped objects can be seen. In the illustration below, two instances of rhombuses in nature are shown: a diamond and a kite.

The probability for the experiment of drawing two marbles (without replacement) from a bag containing three green, three yellow, and four red marbles = 0.0111
In this question we need to find the probability for the experiment of drawing two marbles (without replacement) from a bag containing three green, three yellow, and four red marbles.
Total marbles in tha bag
= 3 green marbles + 3 yellow marbles + 4 red marbles
= 10 marbles
the probability of drawing one marble from a bag,
P1 = 1/10
Now there are 9 marbles in the bag.
So, the probability of drawing second marble would be,
P2 = 1/9
So, the required probability of drawing two marbles (without replacement) from a bag would be,
P = P1 * P2
P = 1/10 * 1/9
P = 1/90
P = 0.0111
Therefore, the probability of drawing two marbles (without replacement) from a bag = 0.0111
