Liz has 28 coins in her pockets that are nickels and quarters. She has a total of $4.60. How much money does liz have in her pocket from nickels alone?

Answer:  30 feet

Explanation:

Draw a vertical number line.

Mark +20 or simply 20 which is the starting position at the diving board. The value 0 on the number line is the water's surface. The position -10 is the portion 10 feet at the bottom of the pool.

Going from 20 to 0 is 20 feet. Then going from 0 to -10 is another 10 feet.

Overall, you travel 20+10 = 30 feet.

Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,

[tex]-x^2+2x-3[/tex]

A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.

Here, n is any real number.

In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.

Given information-

The first polynomial equations given in the problem is,

[tex](x^2 - 3x)[/tex]

The second polynomial equations given in the problem is,

[tex](-2x^2+ 5x - 3).[/tex]

To find the sum of these two polynomials, add the two terms together as,

[tex](x^2 - 3x)+(-2x^2+ 5x - 3)[/tex]

Let the result of the sum is [tex]f(x)[/tex]. Thus,

[tex]f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3[/tex]

Separate the similar power variable as,

[tex]f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3[/tex]

Thus the sum of the given polynomial in standard form is,

[tex]-x^2+2x-3[/tex]

According to the graph, it can be inferred that the most accurate conclusion is that the older the age, the percentage of 3 points is lower (option c).

The graph shows the relationship between the percentage of 3 points and different ages from 20 years to 50 years. In general, from twenty to 35 are the most points that refer to the percentage of 3 points.

According to the graph, it can be inferred that the most appropriate conclusion for this graph is that the older the age, the percentage of 3 points decreases because most of the points are in a range of 20 to 35 years of age.

After 40 years, there are only 3 points, which indicates a very significant decrease in the percentage of points at older ages.

The 88.5 ft² fabric of each color will be needed to make a single parachute canopy.

Given

The canopy of a parachute is a semicircle with a radius of 13 feet.

A company that is making parachutes for a Fourth of July celebration wants each parachute to be made from equal parts of red, white, and blue fabric.

The area of a semicircle is half of the area of the circle.

The first step is the surface area of the semicircle.

The surface area of a circle is;

[tex]\rm Surface \ area=\pi r^2\\\\Surface \ area=3.14 \times 13^2\\\\Surface \ area =530.929[/tex]

Since the semicircle, we divide this by 2.

S.A of the parachute is;

[tex]\rm =\dfrac{530.929}{2}\\\\= 265.4645[/tex]

To get the fabric is needed for each color we divide this by 3.

The fabric needed for each color is;

[tex]\rm= \dfrac{265.4645}{3}\\\\=88.5[/tex]

Hence, the 88.5 ft² fabric of each color will be needed to make a single parachute canopy.

(Simplification attached as image)

[tex] = > \frac{12}{ {17x}^{2} } = \frac{1}{36x} [/tex]

[tex] = > 17 {x}^{2} = 12 \times 36x[/tex]

Answer :

According to the Question

Diameter of a circle field is 40m and that of another 96m .

We have to find the diameter of the circle whose area is equal to the sum of the area of given two circular fields.

Radius of field whose diameter is 40 m

→ r = 40/2 = 20m

Radius of field whose diameter is 96 m

→ r' = 96/2 = 48m

Now, calculating the diameter of Larger circular field.

Let the radius of larger field be R m .

Now, according to the given statement

Sum of Area of given two circular fields = Area of larger field

➠ πr² + πr'² = πR²

➠ π ( r² + r'²) = π R²

➠ 20² + 48² = R²

➠ 400 + 2304 = R²

➠ 2704 = R²

➠ √2704 = R

➠ 52 = R

Therefore, Diameter = 2 × R = 2×52 = 104 m

So, the diameter of Larger circular field is 104 m .

Answer:

Area of circular field(2)=[tex]πr^2[/tex]

=[tex]π×(20)^2[/tex]

=[tex]400π[/tex]

Area of circular field(2)=[tex]πr^2[/tex]

=[tex]π×(48)^2[/tex]

=[tex]2304π[/tex]

Let the radius of circular field that is formed so be r meter(m).

Now,

[tex] \cancel\pi {r}^{2} = 2704 \cancel\pi[/tex]

[tex] {r}^{2} = 2704[/tex]

[tex]r = \sqrt{2704} [/tex]

[tex]r = 52 \: m[/tex]

Diameter=[tex]2r[/tex]

Diameter=[tex]2×52[/tex]

Diameter=[tex]104 m[/tex]

The volume of the box is 56 cm ^3

The surface area or the amount of cardboard used is 100 cm ^3

Step-by-step explanation:

for the volume you multiply the top the side and the bottom of the box together 7*4*2=56 ^3

For the amount of cardboard used we have to find the area of all the sides then add them together. 7*4=28 28*2=56. we multiply it by 2 because there is 2 sides with the same measurements for each side.

2*4=8 8*2=16

2*7=14 14*2=28
