Step-by-step explanation:

For us to know if the options are correct, we just have to multiply the length the rope was cut into by the number of pieces and check if it equals 504 centimeter.

A. 12 pieces of 42.3 centimeter long rope.

= 12 × 42.3

= 507.6

This is wrong

B. 15 pieces of 33.6 centimeter long rope

= 15 × 33.6

= 504cm

This is correct

C. 16 pieces of 31.5 centimeter long rope

= 16 × 31.5

= 504cm

This is correct

D. 20 pieces of 25 centimeter long rope

= 20 × 25

= 500cm

This is incorrect

E. 35 pieces of 14.4 centimeter long rope

= 35 × 14.4

= 504cm

This is correct

Therefore, the correct option are B, C and E.

Answer:

Step-by-step explanation:

Step one:

given data

we are told that before tax the bill is pretax= $78

the tax is 8%

and he left 20% of the pretax for the attendant.

Step two:

let us find the amount he paid for eating with tax

=8/100*78

=0.08*78

=$6.24

with tax the meal cost  is

= 78+6.24

=$84.24

let us solve for the tip he left  (note: it is 20% of the pretax)

=20/100*78

=0.2*100

=$15.6

the tip is $15.6

Step three:

the total amount he paid after eating plus tax and tip is

78+6.24+15.6

=$99.84

Step-by-step explanation:

i hope i didnt answer too late i see that ot says 7 min remaining but oh well  

the answer

equation: (7x-13)+(x+29)+(3x + 5) = 180    (the reason why i put = to 180 is because every triangle adds up to 180 degrees)

first of all add the numbers: 29-13+5 = 21--- then add variables: 7x+3x+x= 11x

you get ur equation as: 11x  + 21 = 180--- 180-21=11x---159=11x--- 159/11=14 9/20

x = 14 9/20 permiter = 88.15 + 43.45 + 48.35 = 179.95

really hope this helps :) good luck

Answer:

a = 5√7

Step-by-step explanation:

Sides of a right triangle follow the Pythagoras theorem,

By Pythagoras theorem,

(AB)² = (BC)² + (AC)²

c² = a² + b²

If b = 9 and c = 16,

(16)² = a² + 9²

256 = a² + 81

a² = 256 - 81

a = √175

a = 5√7

Therefore, measure of third side a = 5√7

The graph will be Option C. passing through the point y = -2

The equation of line is y = -2 and the graph will be passing through the point y = -2

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Now , the equation of the line is given by

2y + 4 = 0

Subtracting 4 on both sides , we get

2y = -4

Divide by 2 on both sides , we get

y = -2

Therefore , the equation of line is y = -2

So , the line graph will be having a straight line 2 units down on the negative y-axis

Hence , the equation of line is y = -2 and the graph will be passing through the point y = -2

Answer:

Step-by-step explanation:

Step one:

given data

P= $1299.99

r=18%= 0.18

minimum rate r= 7%

t=1year

say the account is on simple interest the maximum payment is when the APR is 18%

A=P(1+rt)

A= 1299.99(1+0.18*1)

A= 1299.99(1.18)

A=1533.9882

$1533.9882

The minimum amount is when APR ia 7%

A=P(1+rt)

A= 1299.99(1+0.07*1)

A= 1299.99(1.07)

A=1390.9893

$1390.9893

Answer:

D

Step-by-step explanation:

Its an abs value so you have to solve twice. Once for d - 3.5 < or equal to 1.5 which equals 5. You also have to solve for d - 3.5 > or equal to -1.5 which equals 2. So on the graph it has to be less than 5 and greater than 2 so you just connect the two and draw the line over the numbers in between the 2 and 5.

Answer:

y = 2/5x + 1/5

Step-by-step explanation:

y - y1 = m(x - x1)

y - 1 = 2/5(x - (-3))

y - 1 = 2/5(x + 3)

y - 1 = 2/5x + 6/5

y = 2/5x + 6/5 - 5/5 (since 1 equals to 1/1, 2/2, 3/3, etc.)

y = 2/5x + 1/5

Answer:

D-159

Step-by-step explanation:

The required measure of angle ABD is 142°. Option B is correct.

Given that,
Triangles ACD and BCD are isosceles. Angle BAC has a measure of 17 degrees and angle BDC has a measure of 52 degrees.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not greater than 180°

Here,
According to the question,
ΔBDC,

∠BDC + ∠BCD + ∠DBC = 180
52 + 52 + ∠DBC = 180
∠DBC = 180 - 104
∠DBC = 76°
Now,
∠ABD = 360 - ∠DBC / 2
∠ABD = [360 - 76] / 2
∠ABD = 284/2
∠ABD = 142°

Thus, the required measure of angle ABD is 142°. Option B is correct.

add 2 to both sides

x\6=11

multiply both sides by 6

x=66

2. -7(3x-4)=91

distribute -7 into parenthesis

subtract 28 from both sides

-21x=63

divide both sides by -21

d) CPCTC

Step-by-step explanation:

The phrase Corresponding Parts of Congruent Triangles are Congruent with the acronym CPCTC, is used as valid reasoning in the provision of a proof, after the existence of congruency between two triangles has been proven

Given that the triangles ΔDOG and ΔCAT have been proven congruent, we have that the corresponding vertices are;

Vertex D corresponds to vertex C

Vertex O corresponds to vertex A

Vertex G corresponds to vertex T

Therefore, given that ΔDOG ≅ ΔCAT, we have;

∠D ≅ ∠C by CPCTC

∠O ≅ ∠A by CPCTC

∠G ≅ ∠T by CPCTC.

Hence , it is to be quadratic function where a has to be less than zero.

Given that ,

The table contains data on the number of people visiting a historical landmark over a period of one week.

We have to find,

The relationship between the day and the number of visitors.

According to the question,

[tex]y = a\sqrt{x} + b[/tex]

And where x = no. of days = 1

y = no. of visitors = 45

45 = a [tex]\sqrt{1}[/tex] + b

45 = a + b

And When x = 2 and y = 86

86 = [tex]a\sqrt{2} + b[/tex]

Solving the equation for the values of a and b.

From equation 1

45 - a = b

Put the value of b in equation 2

86 = [tex]a\sqrt{2}[/tex] + 45 - a

86 - 45 = [tex]a \sqrt{2} - a[/tex]

41 = a ([tex]\sqrt{2} - 1[/tex] )

[tex]a = \frac{41}{\sqrt{2} - 1 }\\\\a = \frac{41}{0.41}[/tex]

a = 100

Put the value of a = 100

45 = 100 + b

45 - 100 = b

b = -55

The required equation is y = 100[tex]\sqrt{x}[/tex] -55.

When  x = 4

[tex]y = 100\sqrt{2} - 55\\\\ y = 100 ( 1.4 ) - 55\\\\y = 140 - 55\\\\y = 85[/tex]

And when x = 5

[tex]y = 100\sqrt{5} - 55\\\\y = 223.5 - 55\\\\y = 168.60[/tex]

y = 168 ( approx )

Therefore, 168 ≠ 158

Since the function rises less and less in later stage , it can not be a first order function.

So, it is to be quadratic function where a has to be less than zero.
