Slope is -4, and (9,5) is on the line.

Answer:

Step-by-step explanation:

Step one:

given

expected  weight= 28pounds

Actual weight= 25 pound

Required:

percent error

[tex]\delta = \left| \frac{v_A - v_E}{v_E} \right| \cdot 100\%[/tex]

δ= percent error

vA =actual value observed

vE =expected value

δ=25-28/28*100

δ=-3/28*100

δ=0.107*100

δ=10.7%

The percent error is 10.7%

When completing the square is carried out on the quadratic [tex]x^2+11x[/tex] we get

[tex]x^2+11x+\dfrac{121}{4}[/tex]

when expressed as a binomial squared, we get

[tex]\left(x+\dfrac{11}{2}\right)^2[/tex]

To complete the square, we need to add a term to the expression

[tex]x^2+11x[/tex]

that would make it a perfect square. Generally, given the quadratic expression

[tex]x^2+bx[/tex]

to make it a perfect square, we have to add half the square of the coefficient of [tex]x[/tex]. That is, add [tex]\left(\frac{b}{2}\right)^2[/tex], or [tex]\frac{b^2}{4}[/tex] to the quadratic expression to get

[tex]x^2+bx+\dfrac{b^2}{4}[/tex]

which, when factored into a binomial squared becomes

[tex]\left(x+\dfrac{b}{2}\right)^2[/tex]

In our case, the quadratic [tex]x^2+11x[/tex] will become

[tex]x^2+11x+\dfrac{121}{4}[/tex]

and when expressed as a binomial squared, we get

[tex]\left(x+\dfrac{11}{2}\right)^2[/tex]

Given :

A group of 106 campers sits in a big circle.

The camp leader tells them to say "hello" to each camper sitting to their left and right.

To Find :

What is the total number of times the campers say "hello".

Solution :

It is given that each camper say "hello" to each camper sitting to their left and right i.e each camper says "hello" twice.

Therefore, 106 campers will say hello = 106 × 2 = 212 times.

Hence, this is the required solution.

Answer:

Perimeter of rectangle is 23.34

Step-by-step explanation:

The coordinates of the vertices of a rectangle are (-4, 3), (-1, 5),(3, – 1), and (0, – 3).

What is the perimeter of the rectangle?

The formula to find perimeter of rectangle is: [tex]Perimeter=2(l+w)[/tex]

We need to find length and width first using the coordinates (-4, 3), (-1, 5),(3, – 1), and (0, – 3).

Let A=(-4, 3) B=(-1, 5) C=(3, – 1) and D=(0, – 3) according to the figure attached.

So, If we find distance of point AB it can be considered length of rectangle and distance of point AC can be considered width of rectangle

The formula used to find distance is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Finding distance AB, we have [tex]x_1=-4, y_1=3, x_2=-1, y_2=5[/tex]

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-1-(-4))^2+(5-3)^2}\\Distance=\sqrt{(-1+4)^2+(5-3)^2}\\Distance=\sqrt{(3)^2+(2)^2}\\Distance=\sqrt{9+4}\\Distance=\sqrt{13}\\Distance=3.61[/tex]

So distance between point A and B is 3.61

Finding distance AC, we have [tex]x_1=-4, y_1=3, x_2=3, y_2=-1[/tex]

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(3-(-4))^2+(-1-3)^2}\\Distance=\sqrt{(3+4)^2+(-1-3)^2} \\Distance=\sqrt{(7)^2+(-4)^2} \\Distance=\sqrt{49+16} \\Distance=\sqrt{65}\\Distance=8.06[/tex]

So, distance between point A and C is 8.06

We have length = 3.61 and width = 8.06

Using formula of perimeter

[tex]Perimeter=2(l+w)\\Perimeter=2(3.61+8.06)\\Perimeter=2(11.67)\\Perimeter=23.34[/tex]

So, Perimeter of rectangle is 23.34

Answer:

i woluld say B 9.5 IN

Step-by-step explanation:

Answer:

You will get there in 4 hours

Step-by-step explanation:

Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there

Where D = Distance

r = rate = Average Speed

t = time in hours

From the question

D = 220 miles

t = ??

r = 55 miles/hour

Hence:

220miles = 55miles/hour × t

t = 220/55

t = 4 hours

You will get there in 4 hours

Answer:

[tex]0.45 + 0.25q = 3.70[/tex]

Step-by-step explanation:

Given that:

Number of nickels with Ferrell = 9

Number of quarters = [tex]q[/tex]

Value of coins = $3.70

To find:

The equation to find the number of quarters.

Solution:

Value of a nickel = 5 quarters = $0.05

Value of 9 nickels = [tex]9 \times 0.05 = \$ 0.45[/tex]

Value of a quarter = $0.25

Value of [tex]q[/tex] quarters = $0.25[tex]q[/tex]

Total value of coins = Value of 9 nickels + Value of [tex]q[/tex] quarters[tex]\$0.45 + \$0.25q = \$3.70\\\Rightarrow 0.25q=3.70-0.45\\\Rightarrow 0.25q=3.25\\\Rightarrow q =13[/tex]

So, the answer is, number of quarters available with Ferrell = 13

The equation to be used to find the number of quarters, [tex]q[/tex]:

[tex]0.45 + 0.25q = 3.70[/tex]

Answer:

13 1/3

Step-by-step explanation:

So the question is Marita's nose is 2 inches long and her head is 9 inches tall. Assume Mount Rushmore was carved using the same ratio. If Teddy Roosevelt's head is 60 feet tall, how long should his nose be? Round to the nearest foot, if necessary.

First divide 60 by 9 to figure out the first part of the ratio. So that is 60/9 or    6 2/3.

Then multiply 2 by 6 2/3 which is 13 1/3.

Finally when rounded to the nearest foot, it will be 13.

Answer:

2

Step-by-step explanation:

x²+2xy+y²

Here x² has degree 2

2xy has degree also 2 because x has 1 degree and y has 1 degree so 1+1=2

y² has degree 2

So the highest degree of the expression is 2

Answer:

m=4

Step-by-step explanation:

−9(m+3)+14=−49

Step 1: Simplify both sides of the equation.

−9(m+3)+14=−49

(−9)(m)+(−9)(3)+14=−49(Distribute)

−9m+−27+14=−49

(−9m)+(−27+14)=−49(Combine Like Terms)

−9m+−13=−49

−9m−13=−49

Step 2: Add 13 to both sides.

−9m−13+13=−49+13

−9m=−36

Step 3: Divide both sides by -9.

−9m

−9

=
