Can Someone Explain This To Me , I'm Behind In A Lot Of Homework

Answers

Answer 1

Answer:

13: 16

14: 6.28

15: √45

Step-by-step explanation:

13: Count the number of spaces from A to D or B to C, which is 4.

Then, count the number of spaces from A to B or C to D, which is also 4.

After that, multiply the two numbers. You should now have an answer of 16.

14: You want to find the diameter of the circle, which is 2.

Then, multiply 2 by 3.14, aka pi. You should now have an answer of 6.28.

*15: Count the number of spaces from A to C, which is 6.

Then, count the number of spaces from A to B, which is 3.

After that, square both of the numbers. 6 x 6 = 36 and 3 x 3 = 9.

Now, the final step. Add both numbers together. 36 + 9 = 45.

You should now have an answer of √45.

I hope this helped!

Faith wants to add a 20% tip to a $56 restaurant bill. How much will Faith pay including the tip?

Answers

Answer:

67.20$

Step-by-step explanation:

multiply 56 by 1.2

Answer:

$67.2

Step-by-step explanation:

Given:

Price = $56Tip = 20%

∴ Equation: Price + Tip = Total

⇒ 56 + (20/100 × 56) = Total

Simplify the equation to obtain the total:

⇒ 56 + (20/100 × 56) = Total⇒ 56 + (20/50 × 28) = Total⇒ 56 + (20/25 × 14) = Total⇒ 56 + (4/5 × 14) = Total⇒ 56 + (56/5) = Total

Convert the expression in the parenthesis into decimals:

⇒ 56 + (56/5) = Total⇒ 56 + (11.20) = Total

Open the parenthesis and simplify:

⇒ 56 + 11.20 = Total⇒ $67.2 = Total

Faith will pay (including the tip) $67.2.

Find the area of the circle with circumference 2(pi)r cm​

Answers

Answer:

area should be (pi)r^2

Find the area of the figure.

Answers

Step-by-step explanation:

such problems are always the combination of areas of simple figures.

in our case here the simplest way seems to me to calculate the area of the whole 15×15 square (the side lengths are 15 and 9+6 = 15) and then subtract the small 6×6 square (top left), the small 6×3 triangle (bottom right) and the larger 6×9 triangle (top right).

we know that the left side of the main square is 9+6 = 15.

we know that the missing side piece (top right) is also 6 (like its left side). and the right side piece is 15-6-6 = 3.

that is how we know the side lengths of the missing pieces.

so,

15×15 = 225 cm²

the small square is

6×6 = 36 cm²

the large triangle is

6×9/2 = 3×9 = 27 cm²

the small triangle is

6×3/2 = 3×3 = 9 cm²

so, the total area of the figure is

225 - 36 - 27 - 9 = 153 cm²

The trinomial x2 bx – c has factors of (x m)(x – n), where m, n, and b are positive. what is the relationship between the values of m and n? explain.

Answers

The relationship between the values of m and n for the trinomial x²+bx -c is (m+n) is the sum of the roots and (mn) is the product of the roots.

What is trinomial?

A trinomial is the type of algebraic expression in which there are three terms present and more than one variable are present.

The trinomial given in the problem is,

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

This trinomial has factors of,

[tex](x +m)(x - n),[/tex]

Where m, n, and b are positive.

If this factors multiply by each other, we get,

[tex](x +m)(x - n)\\x^2+nx+mx+nm\\x^2+(n+m)x+nm[/tex]

Compare it with the trinomial, we get,

[tex]b=(m+n)[/tex]

Which is the sum of the terms,

[tex]c=nm[/tex]

Which is the product of the terms.

Hence, the relationship between the values of m and n for the trinomial x²+bx -c is (m+n) is the sum of the roots and (mn) is the product of the roots.

Answer: d, the diameter, is about 36.92 units

Step-by-step explanation:

         The c value is the circumference and we are being asked to solve for the diameter.

         We can take the value they give for the circumference, plug it into the circumference formula, and solve for d. Please note that the diameter is two times the radius, or r, so at the end I will multiply r by two.

C = 2πr

(116) = 2πr

18.46 ≈ r

r ≈ 18.46

-

18.46 * 2 = 36.92

     The missing measure is about 36.92 units.

Finding m∠HCG

HE is the diameter line [= 180°]∠ECF + ∠FCG + ∠HCG = 180°60° + 75° + ∠HCG = 180°∠HCG = 180° - 135°∠HCG = 45°

Finding m∡DF

∠ECF + ∠DCE60° + 45°105°

Answer:

m∠HCG = 45°

m∡DF = 105°

Step-by-step explanation:

  m∠ECD + m∠ECF + m∠FCG

= 45° + 60° + 75°

= 180°

As angles on a straight line always sum to 180°, we can conclude that the line DG is a straight line and the diameter of the circle, and the Point C is the center of the circle.

Assuming that line EH is also a straight line, using the vertical angles are always congruent theorem, m∠ECD = m∠HCG.  

Therefore,  m∠HCG = 45°

We always measure arcs in a counterclockwise direction.

⇒ m∡DF = m∡DE + m∡EF

               = 45° + 60°

               = 105°

The length of a rectangle is 8 feet more than its width. the area of the rectangle is 97 ft.² determine the length and width of the rectangle

Answers

Answer:

L =      [tex]\sqrt{113}[/tex] +4

W =     [tex]\sqrt{113}[/tex] -4

or L = 14.63 ft, and W = 6.63 ft

Step-by-step explanation:

Let L be the length and W the width.

We are told that the "length of a rectangle is 8 feet more than its width:"

L = W+8

Area of the rectangle is given by L*W, and is 97 [tex]ft^{2}[/tex]

L*W = 97

Substituting L=W+8, we get:

(W+8)W=97  [tex]ft^{2}[/tex]

[tex]W^{2}[/tex] + 8W = 97

[tex]W^{2}[/tex] + 8W - 97 = 0

The roots to this equation are:

-4-[tex]\sqrt{113}[/tex], and[tex]\sqrt{113}[/tex] -4

Only the second gives a positive value, so W = [tex]\sqrt{113}[/tex] -4

Since L=W+8, the length, L, is  [tex]\sqrt{113}[/tex] -4 + 8 or  [tex]\sqrt{113}[/tex] +4

In decimal:

L = 14.63 ft, and W = 6.63 ft

Which functions have a vertex with a x-value of 0? select three options. f(x) = |x| f(x) = |x| 3 f(x) = |x 3| f(x) = |x| − 6 f(x) = |x 3| – 6

Answers

The functions have a vertex with a x-value of 0 will be f(x) = |x|,f(x) = |x|+ 3 and f(x) = |xl - 6.Option 1,2 and 4 are  functions have a vertex with a x-value of 0.

What is a function?

A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.

The standard absolute value function is found as;

[tex]\rm f(x) = a|x - h| + k[/tex]

Where,

(h, k) denotes to the vertex

h is the vertex of the x-coordinate

k is the y-coordinate of the vertex

By comparing the standard equation with the given equation in the options we will get the functions to have a vertex with an x-value of 0;

[tex]\rm f(x) = |x| \\\\ \rm f(x) = |x| + 3 \\\\ f(x) = |x| - 6[/tex]

The functions have a vertex with a x-value of 0 will be f(x) = |x|,f(x) = |x|+ 3 and f(x) = |xl - 6.Option 1,2 and 4 are  functions have a vertex with a x-value of 0.

Hence options 1,2 and 4 are functions that have a vertex with an x-value of 0.
