~Let's change 9.9² to 10² since we have to estimate.~
We know that:
10² = 100Given expression: 9.9² × 1.79Solving the expression:
9.9² × 1.79=> 10² × 1.79=> 100 × 1.79=> 179The estimated value of 9.9² × 1.79 is 179.
Solution (b):~Let's change √97.5 to √100 and 1.96 to 2 since we have to estimate.~
We know that:
√100 = 10Given expression: √97.5 ÷ 1.96Solving the expression:
√97.5 ÷ 1.96=> √100 ÷ 2=> 10 ÷ 2=> 5The estimated value of √97.5 ÷ 1.96 is 5.

Answer:
7/10 of 40.
Step-by-step explanation:
It would be 7/10 of 40 because do you know what they equal because I bet If I Said what they equal it would be easier for you.
7/10 or 70% of 40=28
And for 2/3 or 66.67 of 36=24 so 28 is a bigger number than 24 so 7/10 of 40 is bigger.

Answer:
17 rows
Step-by-step explanation:
We know that f(x) = 2x² - 10x models the total number of spaces and x models the number of rows.
Since we are given the total number of spaces of 408. We let f(x) = 408
2x² - 10x = 408
Now we solve as a quadratic, subtract 408 to both sides
2x² - 10x - 408 = 0
Divide 2 on both sides
x² - 5x - 204 = 0
We look for terms that multiply to -204 and add to -5.
Those terms are -17 and 12
x² - 17x + 12x - 204 = 0
x(x-17) + 12(x-17)
(x+12)(x-17)
x = -12 x = 17
We can not have -12 rows but we can have 17 rows.
17 rows is the answer.

Answers
Question :-
If the Reactangle has length of 15 cm and the Breadth of 20 cm . Calculate the Area of Rectangle .Answer :-
Area of Rectangle is 300 cm² .Explanation :-
As per the provided information in the given question, we have been given that a Rectangle has the Length as 15 cm and it's Breadth is given 20 cm . And, we have been asked to calculate the Area of Rectangle .
For calculating the Area of Rectangle , we will use the Formula :-
[tex] \bigstar \: \: \boxed {\sf {Area \: of \: Rectangle = Length \times Breadth}} [/tex]
Therefore , by Substituting the given values in the above Formula :-
⇒ Area of Rectangle = Length × Breadth
⇒ Area of Rectangle = 20 × 15
⇒ [tex] \textbf {\textsf {Area of Rectangle = 300 cm²}} [/tex]
[tex] \underline {\rule {180pt} {4pt}} [/tex]
The area of the given rectangle.
Solution:[tex]area = length \times width[/tex]
[tex]a = 15 \times 20[/tex]
[tex]a = 300 \: {cm}^{2} [/tex]
Therefore, the area of the given rectangle is 300 square centimeters.

find the value of x in the triangle shown below
Answers
Answer:
61
Step-by-step explanation:
We see that the triangle is isosceles as the two sides of it are 6.
In an isosceles triangle, you have two sides that are the same and two angles that are the same.
The two congruent angles will be opposite to the congruent sides.
So, we know that both angles must be x.
The Angles of a triangle add up to 180 degrees.
2x + 58 = 180
2x = 122
x = 61 ddegrees
Solution:
We know that:
Sum of interior angles of triangle: 180°We can see that the two lines of the triangle are equivalent.
This means that:
The triangle is an isosceles triangle.The bottom angles must be equivalent.Equation created: 58 + x + x = 180
Simplify the LHS.
58 + x + x = 180=> 58 + 2x = 180Subtract 58 both sides.
=> 58 - 58 + 2x = 180 - 58=> 2x = 122Divide 2 both sides.
2x = 122=> 2x/2 = 122/2=> x = 122/2 = 61Work out the sum of 1/3, 1/5 and 3/10

Step-by-step explanation:
Start by solving for side b

9<15<16.5 there are two possible triangles
sin33/15 = sinB/16.5 = sinB=(16.5sin33)/15
B=36.9, 180-36.9=143.1 Next determine if the angles are correct
36.9+33=69.9 143.1+33=176.1 Both of these are less than 180, two triangles can be drawn.
