Answers

The area of the plant grass is the amount of plant grass on the field

It is true that one bag of grass and seed will be enough

How to determine if the bag will be enough?

The dimension of the rectangular area is:

15 feet by 10 feet

So, the area of the rectangular garden is:

Area = 15 feet * 10 feet

Evaluate the product

Area = 150 square feet

There are bags of grass and seed that will cover 200 square feet.

200 square feet is greater than 150 square feet

Hence, one bag of grass and seed will be enough

Answer:

34 or B

Step-by-step explanation:

180-112=68

68/2=34

Since the 2 angles equal 180, and we already know one is 112, we can subtract that. and because it is 2 times a number, we need to get half of whatever that number is, which was 68, and we got 34. this would be the value of y, because when plugged in, 112+2(34)=180.

The diameter of a circle is 14 inches. What is the circle's area

use 3.14 for PI

Answers

Answer:

153.86 inches²

Step-by-step explanation:

How do we find the radius of a circle?

The radius of a circle is 1/2 of the diameter, so 14/2 = 7 inches

How do we find the area of a circle?

We can find the area of a circle by using πr², where r = radius. We're given the radius as 7 inches and pi as 3.14.

Solving

[tex]3.14*7^2[/tex] [tex]3.14*49[/tex] [tex]153.86[/tex]

Therefore, the answer is 153.86 inches².

Have a lovely rest of your day/night, and good luck with your assignments! ♡

The area of the circle is 153.86 square inches.

We have,

Diameter = 14 inch

Radius= 14/2 = 7 inch

Now, the formula for area of a circle,

Area = π (radius)²

Now we can calculate the area using the radius:

Area = 3.14 x (7 inches)²

Area = 3.14 x 49 square inches

Area ≈ 153.86 square inches

Therefore, the area of the circle is 153.86 square inches.

1) Azalee loves stuffed animals! Initially she had 10 stuffed animals. Her collection continues to grow at a rate of 24% per year. How many stuffed animals will she have in 6 years? Group of answer choices 51 stuffed animals 24 stuffed animals 47 stuffed animals 36 stuffed animals

Answers

Answer:

B. 24 stuffed animals

Step-by-step explanation:

Initial amount of animal = 10

If her collection continues to grow at a rate of 24% per year, then increment in number of animal after 1 year will be:

24% of 10

= 0.24×10

= 2.4

Total increment after 6years will be:

= 2.4×6

= 14.4

Total stuffed animal that she will have after 6years = initial amount + increment = 10+14.4

Total stuffed animal that she will have after 6years = 24.4 ≈ 24 stuffed animals

Answers

Given:

The expression is [tex](x+4y)^2[/tex].

The expression [tex]ax(2x+y-5)[/tex] simplifies to [tex]6x^2+3xy-15x[/tex].

To find:

The equivalent expression.

The value of a.

Solution:

The expression is

[tex](x+4y)^2[/tex]

Using [tex](a+b)^2=a^2+2ab+b^2[/tex], we get

[tex](x+4y)^2=x^2+2(x)(4y)+(4y)^2[/tex]

[tex](x+4y)^2=x^2+8xy+16y^2[/tex]

Therefore, the correct option is A.

The expression [tex]ax(2x+y-5)[/tex] simplifies to [tex]6x^2+3xy-15x[/tex]. So,

[tex]ax(2x+y-5)=6x^2+3xy-15x[/tex]

[tex]2ax^2+axy-5ax=6x^2+3xy-15x[/tex]

On comparing the coefficient of [tex]x^2[/tex],, we get

[tex]2a=6[/tex]

Divide both sides by 2.

[tex]a=3[/tex]

Therefore, the value of a is 3.

Find the vertex of the quadratic function:
y=1/2x^2 + 8x – 50

Answers

Answer:

definition  

The vertex form of a quadratic function is given by

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.

FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form". To avoid confusion, this site will not refer to either as "standard form", but will reference f (x) = a(x - h)2 + k as "vertex form" and will reference f(x) = ax2 + bx + c by its full statement.

When written in "vertex form":

• (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

• the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).

• the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).

• notice that the h value is subtracted in this form, and that the k value is added.

            If the equation is y = 2(x - 1)2 + 5, the value of h is 1, and k is 5.

            If the equation is y = 3(x + 4)2 - 6, the value of h is -4, and k is -6.

Method 1: Completing the Square

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example.
