An equilateral triangle has sides of length 16.1 cm, correct to the nearest millimetre.
Find the lower and upper bounds of the perimeter of the triangle.

Answers

Answer:

48.3 cm is the lower and upper bound of the perimeter.

Step-by-step explanation:

For any equilateral triangle, by definition, the

lengths of the sides of the triangle are the same.

Thus, the perimeter of the triangle is 16.1 + 16.1 + 16.1 = 3(16.1) = 48.3 cm.

Thus, the upper and lower bounds are the same and are both equal to

48.3 cm.

Zoe needs to rent a car. Kara's Kar Kompany charges $22 per day and a $100 cleaning fee. Callie's Car Company charges $26 per day and has a $40 cleaning fee. After how many days would the rental cost be the same for both car rental companies

Answers

Answer:

15 days

Step-by-step explanation:

Step 1 - Put in equation form:

22d + 100 = t

26d + 40 = t

Step 2 - Simplify equations:

22d + 100 = 26d + 40

100 - 40 = 26d - 22d

60 = 4d

d = 60/4

d = 15

Find the measure of each angle.

ZUVW and ZXYZ are complementary angles, mZUVW= (x - 10), and mZXYZ= ( 4X – 10),

Answers

Answer:

<ZUVW = 12 degrees

<ZXYZ = 78 degrees

Step-by-step explanation:

x - 10 + 4x - 10 = 90

5x -20 = 90

5x = 90 + 20

x = 110/5

x = 22

mZUVW = 22 - 10 = 12 degrees

mZXYZ = 4(22) - 10

= 78

how do i work out -2=6+a/5

Answers

Answer:

a = -40

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

[tex]-2 = 6 + \frac{a}{5}[/tex] [tex]-2 = 6 + \frac{1}{5}a[/tex] [tex]-2 = \frac{1}{5}a + 6[/tex] [tex]\frac{1}{5}a + 6 = -2[/tex]

Step 2: Subtract 6 from both sides.

[tex]\frac{1}{5}a + 6 - 6 = -2 -6[/tex] [tex]\frac{1}{5}a = -8[/tex]

Step 3: Multiply both sides by 5.

[tex]\frac{1}{5}a * 5 = -8 * 5[/tex] [tex]a = -40[/tex]

Therefore, a = -40. I hope this helped you!

Answer:

-40 = a

Step-by-step explanation:

-2=6+a/5

Subtract 6 from both sides of the equation

-8 = a/5

Multiply both sides by 5

(5)-8 = a/5(5)

-40 = a

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3

Step-by-step explanation:

All you really have to do for all of the problems is substitute your value of "x" for the function.

17.) f(x) = 8x - 7; f(x) =17

    17 = 8x -7  ---- substitute 17 for f(x), add 7 on both sides

    24 = 8x ------ divide 8 on both sides

    x = 3

18.)    g(x) = -4x + 7; g(x) = 27

           27  = -4x + 7  substitute 27 for g(x), subtract 7 on both sides

           20 = -4x

            x = -5

y=8x - x^2
y=2x
step by step solution

Answers

Answer:

(0,0) and (6,12)

Step-by-step explanation:

8x - x^2 = 2x

8x -2x -x^2 =0

6x -x^2 = 0 then factor out a common x

x (6-x) = 0

so x =0 or 6-x=o

x=6

so if x=o y=2x=2(0)=0

and if x=6 y =2x =2(6)= 12

What is 7x-1+6x-1=180? SHOW WORK!!!!!!

7x - 1 + 6x - 1 = 180

add the x’s, add the numbers

13x - 2 = 180

add 2 to 180

13x = 182

divide 182 by 13

x = 14

Answer:

Step-by-step explanation:

7x -1 +6x -1 = 180, group like terms

7x+6x -1 -1 = 180, combine like terms

13x -2 = 180, add 2 to both sides

13x -2+2 = 180+2 , solve the additions

13x = 182, divide both sides by 13

13x/13 = 182/13, solve the divisions

which of the following does not correctly refer to the slope of a line?

a. m = x2-x1/y2-y1

b. it represents the steepness of a line

c. m = rise/run

d. it is the ratio of the vertical change to the horizontal change​

Answers

Answer:

D

Step-by-step explanation:

d is incorrect because it's saying the vertical (x) is over the horizontal change (y) and we know that's wrong because it's y/x or rise/run

The option that does not correctly refer to the slope of a line is:

a. m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]

Option A is the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

We have,

The slope of a line:

a.

m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]

The slope formula is:

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

So,

m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex] is not correct.

b. it represents the steepness of a line.

The slope of a line is the steepness of the given line on the graph.

It is correct.

c. m = rise/run

The slope can also be termed as rise/run.

It is correct.

d. it is the ratio of the vertical change to the horizontal change​

The slope of a line is given as:

m = Vertical change / Horizontal change

It is correct.

Thus,

The option that does not correctly refer to the slope of a line is:

a. m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]

Option A is the correct answer.

Shade one more square to make a
pattern with rotational symmetry order 2.

Answers

Answer:

shade the square that is 1 above the bottom right

To make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

What is rotational symmetry?

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same. Many geometrical shapes appear to be symmetrical when they are rotated 180 degrees or with some angles, clockwise or anticlockwise.

Given is a figure of square box, of 5x5, we need to complete the shaded part so, that the resulting figure will be rotational symmetric,

Since, the figure needs to be rotational symmetric, that means, the figure will be same no matter how many times we rotated it,

If we shade the one square which is the last box of the fourth line, then it will be a figure which is rotational symmetric.

Hence, to make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

3/20*60

180/20

9

Answer:

The answer is 9

Step-by-step explanation:

15% * 60

"OF" mean multiplication so we multiple

¹/100 * 60

we cancel "Zero cancel Zero"

we left with

¹/10 * 6

but we can make the fraction to be uniform

so we say ¹/10 * /1

we multiply

15 * 6=90

10 * 1=10

/10

we divide

10 into 90 is 9

10 into is 1

so we say /1 is the same as 9.

Hence our answer is 9

The equation that represents the situation is x/3 = 4. And the number of servings that the original recipe makes will be 12.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Gary is making a dish yet they just necessities 1/3 of the first serving size. In the event that the quantity of servings Gary needs is 4.

Let 'x' be the number of servings. Then the equation is given as,

x/3 = 4

Simplify the equation, then we have

x / 3 = 4

x = 12

The condition that addresses what is happening is x/3 = 4. What's more, the number of servings that the first recipe causes will be 12.

Answers

Answer:

in two bouquets of flowers there would be, 12 roses and 20 white carnations.

Step-by-step explanation:

In each bouquet there are 6 roses and 10 white carnations, if there's 2 bouquets of flowers that means that there 2 x 6 and 2 x 10.

2 x 6 (or 6 + 6) = 12

2 x 10 (or 10 + 10) = 20

so in two bouquets there are 12 roses and 20 white carnations.

because in a single bouquet there are 6 roses and 10 white carnations so just double it!

hope that helps

2 x 6 = 12

2 x 10 = 20

There are 12 roses and 20 carnations.
