Answer:

Lucy had 40 books last year.

Step-by-step explanation:

assuming 100% is the percent;

100% + 70%

100 : x

170 : 68

cross multiply = 170x = 100 x 68

-------- ————-

170 170

cancel 170/170

therefore x = 100 x 68 divided by 170

result is 40

The number of books that Lucy has last year will be 40 books.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Lucy has 68 books. This number of books is 70% more than the number of books she had last year.

Let 'n' be the number of books. Then the equation is given as,

1.7 n = 68

n = 68 / 1.70

n = 40

The number of books that Lucy has last year will be 40 books.

Answer:

B. Angle X is the largest angle.

C. Angle Z is greater than angle Y.

E. Line segment X Z is the shortest side.

Step-by-step explanation:

YZ = 2n, XZ = n - 2, XY = n + 4 and n ≥ 5.

YZ - XZ = 2n - (n - 2) = n + 2. but n ≥ 5, hence YZ - XZ = n + 2 ≥ 7.

YZ > XZ

YZ - XY = 2n - (n + 4) = n - 4. but n ≥ 5, hence YZ - XY = n - 4 ≥ 1

YZ > XY

XY - XZ = n + 4 - (n - 2) = 6: XY > XZ

Therefore:

YZ > XY > XZ

The angles are proportional to their opposite sides, hence:

∠X > ∠Z > ∠Y

A. Line segment XY is the longest side.

This is wrong because YZ is the longest side.

B. Angle X is the largest angle.

This is correct. ∠X is the largest angle because it is opposite to the longest side (YZ)

C. Angle Z is greater than angle Y.

This is correct. ∠Z is opposite to the side XY while ∠Y is opposite to the side XZ

D. Line segment XZ is opposite the largest angle.

This is wrong. ∠X is the largest angle which is opposite to the longest side (YZ)

E. Line segment X Z is the shortest side.

This is correct

Answer:

D. Add 21 to both sides of the equation.

The answer is b = 198.

Check the solution by substituting 198 for b.

Step-by-step explanation:

D. 21-21= 177+21=198

     0

198-21=177

The steps are needed to solve b - 21 = 177 equation are:

Add 21 to both sides of the equation.

The answer is b = 198.

Check the solution by substituting 198 for b.

"It is a statement which consists of equal symbol between two mathematical expressions."

"It is the set of all values that that make an equation true."

For given question,

We need to solve the equation b - 21 = 177

⇒ b - 21 = 177                                ................(original equation)

⇒ b - 21 + 21 = 177 + 21                 .................(Add 21 to each side)

⇒ b = 198

Therefore, the steps are needed to solve b - 21 = 177 equation are:

Add 21 to both sides of the equation.

The answer is b = 198.

whats the question? I ca answer it if you tell me :)

Step-by-step explanation:

Answer:

y=x

Step-by-step explanation:

The graph is going 1 up and 1 to the right. You can plug in a value for x and get y. So if you plug in 1 for x, you get 1 for y and if u plug in 2 for x, you get 2 for y, so when you graph (1, 1) and (2, 2) you know the graph is y=x.

Given:

[tex]x^2+kx-98=0[/tex]

One of the two roots of the given equation is double  the additive inverse of the other.

To find:

The value of k.

Solution:

Let two roots of the given equation are [tex]\alpha[/tex] and [tex]\beta[/tex].

According to the question,

[tex]\beta=2(-\alpha)[/tex]        (Additive inverse of [tex]\alpha[/tex] is [tex]-\alpha[/tex])

[tex]\beta=-2\alpha[/tex]

If [tex]\alpha[/tex] and [tex]\beta[/tex] are roots of the quadratic equation [tex]ax^2+bx+c=0,[/tex] then

[tex]\alpha+\beta=-\dfrac{b}{a}[/tex]

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

We have,

[tex]x^2+kx-98=0[/tex]

Here, a =1, b=k and c=-98.

[tex]\alpha+\beta=-\dfrac{k}{1}[/tex]

[tex]\alpha-2\alpha=-k[/tex]           [tex][\because \beta=-2\alpha][/tex]

[tex]-\alpha=-k[/tex]

[tex]\alpha=k[/tex]           ...(i)

Now,

[tex]\alpha\beta=\dfrac{c}{a}[/tex]

[tex]\alpha(-2\alpha)=\dfrac{-98}{1}[/tex]          [tex][\because \beta=-2\alpha][/tex]

[tex]-2\alpha^2=-98[/tex]

Divide both sides by -2.

[tex]\alpha^2=49[/tex]

Taking square root on both sides.

[tex]\alpha=\pm \sqrt{49}[/tex]

[tex]\alpha=\pm 7[/tex]

Using (i), we get

[tex]k=\pm 7[/tex]

Therefore, the value of k is either -1 or 1.

Answer:

I believe the answer is C. 1,131 miles

Step-by-step explanation:

When we use a right triangle to solve, we already know the angles on the right triangle must be 45 45 90, since all triangles equal 180. Then using tan45 times 800 we get the side between Houston and Lincoln which is also 800. Pythag then solves 800²+800²=c²

c²=1280000  so √1280000 =1131

The answer is C.)

The side of Lincoln to Tallahassee is the largest. The distance between Houston and Tallahassee is smaller, meaning that it is accurately a larger number. It would be simple to understand that the base and height of the triangle could NOT add up to 1,600 because they would both have to be at least HALF the length of the distance between Tallahassee but they are not. Meaning the answer is 1,321
