FACTS TO KNOW BEFORE SOLVING :-
[tex]\sin x = \frac{1}{cosec \: x} \: \: or \: \: cosex \: x = \frac{1}{\sin x}[/tex][tex]\cos x = \frac{1}{\sec x} \: \:or \: \: \sec x = \frac{1}{\cos x}[/tex][tex]\tan x = \frac{\sin x}{\cos x}[/tex]________________________________________________________
In the question ,
L.H.S. = [tex]\sin x (\sec x + cosec \: x)[/tex]
R.H.S. = [tex]\tan x + 1[/tex]
Lets solve L.H.S. first.
[tex]\sin x (\sec x + cosec \: x)[/tex]
[tex]=> \sin x( \frac{1}{\cos x} + \frac{1}{\sin x} )[/tex]
[tex]=> \frac{\sin x}{\cos x} + \frac{\sin x}{\sin x}[/tex]
[tex]=> \tan x + 1[/tex]
∴ L.H.S. = R.H.S. (Proved)
Choose Yes or No to tell if the number 3 will make each equation true. 2 ÷ □ = 3 2 Choose... 2 ÷ 6 = □ Choose... 2 ÷ □ = 2 3 Choose... □ ÷ 8 = 3 8 Choose...
Answer:
1 no
2 yes
3 no
4 no
Step-by-step explanation:
2 ÷ □ =2/3, □ ÷ 8 = 3/8 is true for x is true which equation choose is yes.
What is Division?A division is a process of splitting a specific amount into equal parts.
We have to choose yes or no to tell if the number 3 will make each equation true.
2÷□=3/2
To get 3/2 we have to divide two by three.
2/3=3/2
These are not equivalent so it is not yes.
The other expression 2 ÷ 6 = □
2 ÷ 6=1/3 which is not 3, so it is no.
The third expression
2 ÷ □ = 2/3
When we put 3 in the blank place we get two divided by three.
2 ÷ 3=2/3
Which is true so answer is yes for 3.
□ ÷ 8 = 3/8
When we put three in the blank we get three divided eight which is true.
3÷ 8 = 3/8 which is yes for 3.
Hence, 2 ÷ □ =2/3, □ ÷ 8 = 3/8 is true for x is true which choose is yes.

Using rules, we can simplify expressions with exponents, factorize, or expand them. [tex]2 x \sqrt{10 x}-2 x \sqrt{5}.$[/tex] Thus option D is correct,
What is the exponents and algebraic manipulation?We can simplify the expression using the rules of exponents and algebraic manipulation.
[tex]$\sqrt{5 x}\left(\sqrt{8 x^2}-2 \sqrt{x}\right) = \sqrt{5 x} \cdot \sqrt{8 x^2} - 2\sqrt{5 x} \cdot \sqrt{x}$[/tex]
[tex]$= \sqrt{(5x)(8x^2)} - 2\sqrt{(5x)(x)}$[/tex]
[tex]$= \sqrt{40x^3} - 2\sqrt{5x^2}$[/tex]
[tex]$= \sqrt{4x^2 \cdot 10x} - 2x\sqrt{5}$[/tex]
[tex]$= 2x\sqrt{10x} - 2x\sqrt{5}$[/tex]
Hence, the simplified product where [tex]$x \geq 0: \sqrt{5 x}\left(\sqrt{8 x^2}-2 \sqrt{x}\right)$ is $2 x \sqrt{10 x}-2 x \sqrt{5}.$[/tex]
Therefore, Using rules, we can simplify expressions with exponents, factorize, or expand them. the correct option is $(D) [tex]2 x \sqrt{10 x}-2 x \sqrt{5}.$[/tex]

The perimeter
particular rectangle is
36 centimeters. The longer sides of the rectangle are
cach 2 centimeters longer than each of the shorter sides
of the rectangle. What is the length, in centimeters, of
one of the longer sides of this rectangle"?
Answer:
Long side of the rectangle: 11cm
Shorter side of the rectangle: 7cm
Step-by-step explanation:
36cm divided by 4 = 9
9-2=7
take that two and add it to the other two nines
9+2=11
The required length of the longer sides of rectangle is 10cm.
The perimeter of the rectangle is 36 centimeters,
length = 2+ width
rectangle is four sided polygon whose opposites sides are equal and has angle of 90° between its sides.
Perimeter = 2 length x 2 width
36 = 2(2+width) x 2width
36= 4 (1+width)
width = 8
length= 2+width
length = 2+ 8
length = 10 centimeters
Thus, The required length of the longer sides of rectangle is 10cm.

Let x be the total money was in her wallet and m be the cost of each petunia,
From the given table , the money left in wallet after purchasing 2 petunia =$6.50
Then we have the following equation: 6.50 = x - 2m - - - - - ( 1 ) Also, the money left in wallet after purchasing 8 petunia =$5 Then, we have 5 = x - 8m - - - - - - - - - ( 2 ) Subtracting (2) from (1) , we get 6.50 - 5 = -2m - (8m) then -2m + 8m = 1.50 then we 6m = 1.50. m = 1.50/6 = 0.25 hope this helped.

A bowl contains equal-sized gumdrops. If the bowl has 30 green gumdrops and 1 blue gumdrop, plot an X on the number line below which could represent the probability of randomly choosing a green gumdrop from the bowl.
Explain how you determined your answer.
Answer:
≈ 0.97
Step-by-step explanation:
Given that :
Number of green gum drops = 30
Number of Blue gum drops = 1
Total number of gum drops :
(Number of blue + number of green gum drops)
(30 + 1) = 31
Probability = Required outcome / Total possible outcomes
P(green gum drops) = number of green drops / total number of gum drops
P(green gum drops) = 30 / 31 = 0.967 ≈ 0.97

One rectangular solid with a square base has twice the height of another rectangular solid with a square base with the same side length. Which statements about the two rectangular solids are true?
Check all that apply.
The bases are congruent.
The solids are similar.
The ratio of the volumes of the first solid to the second solid is 8:1.
The volume of the first solid is twice as much as the volume of the second solid.
If the dimensions of the second solid are x by x by h, the first solid has 4xh more surface area than the second solid.
Answer:
First rectangular solid and second Rectangular solid
1. Bases are in the form of square having same dimensions
2. Height of first rectangular solid=2 ×Height of second rectangular solid
The true statements are
A) The bases are congruent.→The meaning of term congruent is that , the two bases are in the shape of square having same dimensions.
(B) No, The solids are not similar.as ratio of side lengths in not same in each case , because the ratio of heights of two solid is equal to .
(D) Volume of first solid = x *x*2 H=2 x²H
Volume of second solid = x*x*H=x²H
Ratio of volumes =2:1
So, option (D) is true.
(E) Surface area of first solid =2[x*x+x*2 H+2 H*x]
=2[x²+4 H*x]=2 *x*[x+4* H]
Surface area of second solid = 2[x*x+x* H+ H*x]=2[x²+2 H*x]=2* x*[x+ 2*H]
Option A, D, E are correct about two solids.

50 POINTS QUICK Mary is three times as old as her son . In 12 years Mary will be twice as old as her son. How old is each of them now?
Answer: Mary is 36 and her son is 12; in 12 years her son will be 24 and she will be 48
Step-by-step explanation:
Answer:
Mary's age = 36
Son's age = 12
Step-by-step explanation:
Let x be age of Mary and y be age of her son.
According to question,
x = 3y...........(1)
And,
x + 12 = 2(y + 12)
x + 12 = 2y + 24
Replacing value of x from (1),
3y + 12 = 2y + 24
3y - 2y = 24 - 12
y = 12
And x = 3 x 12 = 36
