2.73
1.3x2.1=2.73
1.3
x2.1

+26
2.73
Answer:
To multiply 1.3 by 2.1, we need to use the distributive property of multiplication, which states that:
a × (b + c) = a × b + a × c
Using this property, we can break down 2.1 as the sum of 2 and 0.1:
1.3 × 2.1 = 1.3 × (2 + 0.1)
= 1.3 × 2 + 1.3 × 0.1
= 2.6 + 0.13
= 2.73
Therefore, 1.3 multiplied by 2.1 equals 2.73.

Therefore , the solution of the given problem of angles comes out to be
x = 42.5° and y = 20°.
What exactly is an angle?In Euclidean geometry, an arc is a construct made up of two rays that split at the apex and vertex, which are located in the middle of the angle. The sides or loops are the name given to these rays. A combination of two rays may result in an inclination that is inside the surfaces in which they are located. Two planes can be combined to form an angle as well. They are referred to as dihedral angles. Two line rays with end points can be arranged in a variety of ways to create styles in two dimensions.
Here,
Given :
=> 4y + 5y = 180°
=> 9y = 180°
=> y = 180°/9
=> y = 20°
and
=> 2x + 5 + 90° = 180°
=> 2x + 95° = 180°
=> 2x = 85°
=> x = 42.5°
Therefore , the solution of the given problem of angles comes out to be

Find an equation in vertex form for the parabola with focus(1,4)
and
directrix x=5
.
The parabola equation is x = (-1/2)y2 - 4y - 1.5 when the focus and directrix are (1, 4) and 5 respectively.
what is equation ?An equation is a mathematical formula that joins two statements and uses the equal symbol (=) to indicate equivalence. A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign divides the variables 3x + 5 and 14. The relationship between the two sentences on either side of a letter is explained by a mathematical formula. There is frequently only one variable, which also serves as the symbol. for instance, 2x - 4 = 2.
given
The equation's fundamental form is:
4p(x-h) = (y-k) (y-k)
The vertex is at 2 (h,k).
P is the separation between the vertex and the directrix or focus. Between the two is where the vertex is located.
Directrix: x=2, focus: (1, -4).
Vertex at the perpendicular midpoint of (1.5, -4)
Parabola opens left because it faces the focus and moves away from the directrix. This implies that p will be negative. P would be positive if the parabola opened to the right. p = -0.5
Putting this together:
4(-0.5)(x-1.5) = (y-(-4))2
-2(x-1.5) = (y+4)2
-2(x-1.5) = y2 + 8y + 16
x - 1.5 = (-1/2)(y2 + 8y + 16)
x = (-1/2)y2 - 4y - 8 + 1.5
The parabola equation is x = (-1/2)y2 - 4y - 1.5 when the focus and directrix are (1, 4) and 5 respectively.

In an experiment he injects laboratory rats with a small amount of this steroid hormone and, after a suitable waiting period measures the blood glucose level of the rats. In his twelve experimental rats he obtains the following levels of blood glucose {35,36,21,33,34,35,33,35,37,36,38,35}. From previous studies of thousands of normal, un-manipulated rats he knows that the mean (mu) blood glucose level in this species of rat (his laboratory population) is 32 and that the standard deviation is 1.15.

finding the probability of drawing a King from a regular deck of cards
finding the probability of 3 on a six spaced spinner
The compound experiment is the probability of heads on a coin and 4 on a number cube which is P = ( 1/12 )
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability be represented as P
Now , the equation will be
a)
The probability of rolling a 6 on a number cube
The value of P = 1/6
b)
The probability of heads on a coin and 4 on a number cube
Now , the probability of tossing a heads on a coin = 1/2
The probability of rolling a 4 on number cube = 1/6
So , the compound probability P = ( 1/2 ) ( 1/6 )
On simplifying the equation , we get
P = 1/12
c)
The probability of drawing a King from a regular deck of cards
The value of P = 4/52
On simplifying the equation , we get

The area of the circular base of a cone is 25π cm², and the slant height of the cone is four times the radius of the cone.
What is the approximate lateral area of the cone?
Use π≈3.14.
Enter your answer rounded to the nearest whole number
The approximate lateral area of the cone is solved to be 314 cm²
How to find the approximate lateral area of the coneFrom the question we get that:
The area of the circular base of a cone is 25π cm²
25π cm² = πr²
the slant height of the cone is four times the radius of the cone
L = 4r
Lateral area of the cone
= πrl square units.
solving for r
25π cm² = πr²
r² = 25
r = 5
solving for the lateral area of the cone
= πrl square units.
= π * 5 * 4r
= π * 5 * 4 * 5
= 100π

A train does a journey without stopping in 8 hours. if it had traveled 5 km an hour faster, it would have done the journey in 6 hours 40 min. what is its slower speed?
The train which is travelled same distance with two different speeds, the slower speed of a train is 25.075 km/hr
What is the relation between time, distance & speed ?The distance covered by the object is equal to the product of the speed at which the object is moving and time taken for covering the distance.
Distance = Time × Speed
Given that,
A train does a journey without stopping in 8 hours
it had traveled 5 km/hr faster , Time taken = 6 hours 40 min = 6.67hr
slower speed = ?
Suppose total distance covered = X
⇒ X = V × 8 _____(i)
If he travelled 5 km/hr faster
⇒ X = (V+5) × 6.67 _____(ii)
For i and ii distance is same so we can equate both the values,
⇒ V × 8 = (V+5) × 6.67
⇒ 8V = 6.67V + 33.35
⇒ 1.33V = 33.35
⇒ V = 25.075
