PLEASE HELP ME FOR QUESTION 25

Answer:

5/6

Step-by-step explanation:

1/3 x 1/5 = 8/15 then add to 3/10 and you get 5/6 simplifed

The sum of 1/3, 1/5, and 3/10 is 5/6.

Based on the given conditions, formulate 1/3 + 1/5 +3/10

To estimate the common denominator and note the numerators above the common denominator, then we get

10 + 6 + 9/30

Calculate the sum or difference in the above equation, we get

10 + 6 + 9/30 = 25/30

Decrease the fraction to the lower term by canceling the greatest common factor, we get

25/30 = 5/6

Question :-

Answer :-

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.

[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.

Definition of X-intercept: a point where the y-value of the point is equal to 0

  [tex]5x - y = 10\\5x - 0 = 10\\5x = 10\\x = 2[/tex]

Therefore the x-intercept is (2,0).

Definition of Y-intercept: a point where the x-value of the point is equal to 0

 [tex]5x - y = 10\\5(0)-y = 10\\-y = 10\\y = -10[/tex]

Therefore the y-intercept is (0,-10).

Hope that helps!

Answer:

C. 19.5

Step-by-step explanation:

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.

The factorization of [tex]9x^2 - 81[/tex] is given 9(x-3)(x+3). Therefore, (c) is the correct option.

Factorization is the method of simplification of algebraic expressions which contains variables and constants into form that can not be divided into further factors.

To factorize, we first check if any variable or constant can be taken common. Next we check for algebraic identities.

Given in the question,

[tex]= 9x^2 - 81\\\\= 9(x^2 - 9)\\\\=9(x^2-3^2)\\\\=9(x-3)(x+3)[/tex]

identity used : [tex](a^2-b^2) = (a-b)(a+b)[/tex]

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:

We can see that the two lines of the triangle are equivalent.

This means that:

Equation created: 58 + x + x = 180

Simplify the LHS.

Subtract 58 both sides.

Divide 2 both sides.

The value of the function f(g) after simplifying and putting 2 in place of x is -20 and the value of f(g(2)) is 418.

When a function is written inside the another function, then such function is called the composite function.

The first function given in the problem is,

[tex]f(x) = x^2 - x - 2[/tex]

The second function given,

[tex]g(x) = - 6x - 8[/tex]

To find out the value of g(2), put the 2 on place of variable x in the above equation as,

[tex]g(2) = - 6(2) - 8\\g(2)=-12-8\\g(2)=-20[/tex]

The composite function f(g(x)) can be given as,

[tex]f(g(2))= (-20)^2 - (-20) - 2\\f(g(2))=418[/tex]

Thus, the value of the function f(g) after simplifying and putting 2 in place of x is -20 and the value of f(g(2)) is 418.

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:

Supplementary to x is a 90° angle (right angle) which means that both x and the right angle will have to equal 180 degrees:

90 + x = 180

-90        -90

x = 90°

Let's find the angle measure that is supplementary to y.

A 5 sided shape is equal to 540 degrees (you could find this by using the formula: (n - 2) x 180 where n is the number of sides)

so given interior angles:

90 + 80 + 98(supplementary to angle 82 degrees) + 136 + 136(two equal angle measures in the polygon that are missing)

= 540(which is correct), so now we know the two missing angles, 136, besides the angle supplementary to 82 degrees.

136 is supplementary to y so:

136 + y = 180

-136       -136

y = 44°
