Step-by-step explanation:

1. -81/2 or -40.5

Both answers are correct forms I just didn't know if you wanted fraction or decimal form :)

2. Lots of answers for this one but ill give you mine: Mr. Candeleria probably rounded down his estimate number and in most cases like this you should round up.

Hope this helps :)

The solution is

a) The value of the equation is -40.5 or -81/2

b) Percentage error of Mr.Candelaria in estimating the tickets is 13.42 %

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

a)

Let the equation be represented as A

Now , the value of A is

A = ( 3 4/5 )x - ( 2 1/2 )

On simplifying the equation , we get

A = ( 19/5 )x - ( 5/2 )

when x = -10 , substitute the value of x = -10 , we get

A = ( 19 × -2 ) - 5/2

A = -38 - 5/2

A = -81/2

A = -40.5

Therefore , the value of A is -40.5

B)

The measured value = 400 tickets

The true value = 462 tickets

Now , the percentage error in estimating the tickets by Mr. Candelaria is given by the formula ,

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Substituting the values in the equation , we get

Percentage Error = [ | 400 - 462 | / 462 ] x 100

Percentage Error = [ | -62 | / 462 ] x 100

Percentage Error = 0.134199 x 100

Percentage Error = 13.419 %

Therefore , the percentage error is 13.42 %

Hence , the percentage error of Mr.Candelaria in estimating the tickets is 13.42 %

Answer:

5 5/8 miles per hour

Step-by-step explanation:

Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.

We are asked to write the unit rate , this means we are to find out how many miles he can run per hour

Hence,

2/3 hour = 3 3/4 miles

1 hour = x

Cross Multiply

2/3 hour × x = 3 3/4 miles × 1 hour

x = 3 3/4 miles × 1 hour/ 2/3 hour

x = 3 3/4 ÷ 2/3

x = 15/4 ÷ 2/3

x = 15/4 × 3/2

x = 45/8

x = 5 5/8 miles per hour

Answer:

Perimeter of A = 46cm

Area of A = 112cm^2

Perimeter of B = 61cm

Area of B = 118cm^2

Step-by-step explanation:

So there are two shapes. I divided one into 2 parts ( shape A ) . And the other into three ( shape B

Shape A:

PERIMETER = S + S +S +S + S + S + S + S ( THE SHAPE HAS 8 SIDES )

= 5 + 5 + 20 + 11 + 3 + 3 + 5 + 4 ( THIS INCLUDES THE MISSING SIDES )

= 46 CM

AREA- To find the area you divide the shape

Part 1 - 4* 3 = 12cm^2 Part 2 - 20 * 5 = 100cm^2

Final part ( add part a and b ) - 12 + 100 = 112cm^2

Shape B:

PERIMETER = S + S + S + S + S ..,........ (UNTIL YOU GET TO 12 SIDES PROVIDED THE SHAPE HAS 12 SIDES :) )

= 12 + 2 + 2 + 4 + 5 + 4 + 4 + 4 + 6 + 6 + 12 + 5

= 61 CM

AREA- To find the area you divide the shape

Part 1 - 12* 2 = 24cm^2 Part 2 - 4 * 3 = 12cm^2 Part 3 - 12 * 6 = 72 cm ^2

Final part ( add part a, b and c ) - 12 + 72 + 24 = 108cm^2

Answer:

Step-by-step explanation:

Formula

Area = 1/2 (b1 + b2)*h

Givens

b1 = 5

b2 = 11.5

h = 4.5

Solution

Area = 1/2 (5 + 11.5)* 4.5

Area = 1/2 (16.5)*4.5

Area = 1/2 (74.25)

Area = 37.125

Step-by-step explanation:

Answer:

(8, 2)

Step-by-step explanation:

Subtract the two D points.

(-12) - (-3) = -9

21 - 10 = 11

Then, use it to translate.

(17,-9)

(x - 9, y + 11)

= (8, 2)

The image of E(17,-9) under the translation will be (8,2)

The steps are as follow:

D(-3,10)

D'(-12,21)

D'-D = (-12+3,21-10)

X(-9,11)

E' = (17-9,-9+11)

E' = (8,2)

Therefore the image of E(17,-9) under the translation will be (8,2)

nth term = 10 + (n - 1)-3

Step-by-step explanation:

a) 10, 7, 4, 1

First term,a = 10

Common difference,d = 7 - 10 = -3

nth term = a + (n - 1)d

nth term = 10 + (n - 1)-3

b 6, 4, 2,0

First term,a = 6

Common difference,d = 4 - 6 = -2

nth term = a + (n - 1)d

nth term = 6 + (n - 1)-2

c) 9,4 -1,-6

First term,a = 9

Common difference,d = 4 - 9 = -5

Answer:

The all-time medal table for all Olympic Games from 1896 to 2018, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.[1]

The results are attributed to the IOC country code as currently displayed by the IOC database. Usually, a single code corresponds to a single National Olympic Committee (NOC). When different codes are displayed for different years, medal counts are combined in the case of a simple change of IOC code (such as from HOL to NED for the Netherlands) or simple change of country name (such as from Ceylon to Sri Lanka). As the medals are attributed to each NOC, not all totals include medals won by athletes from that country for another NOC, such as before independence of that country. Names in italic are national entities that no longer exist. The totals of NOCs are not combined with those of their predecessors and successors.

Answer:

ΔGJH ≅ ΔEKF

HL: GH and EF

SAS: FK and JH (or GH and EF)

ASA: ∠JGH and ∠FEK (or ∠EFK and ∠JHG)

ΔGFJ ≅ ΔEKH

SSS: KH and FJ

SAS: ∠KEH and ∠FGJ

Step-by-step explanation:

List whatever angles/sides need to be congruent for the two triangles to be congruent.

Prove ΔGJH ≅ ΔEKF using....

- HL (Hypotenuse + Leg)

           We already have two legs that are congruent (EK and GJ), so we just need the hypotenuses (GH and EF) to be equal.

- SAS (Side + Angle + Side)

         1 pair of sides (EK and JG) are equal, and m∠EKF = m∠GJH. So we need one more side. You can either use FK and JH or GH and EF.

- ASA (Angle + Side + Angle)

         1 pair of angles (∠EKF and ∠GJH) are already given as equal, and 1 pair of sides (EK and GJ) are equal. We just need one more pair of angles. So either ∠JGH and ∠FEK or ∠EFK and ∠JHG.

Prove ΔGFJ ≅ ΔEKH using...

- SSS (Side + Side + Side)

          Two pairs of sides (EK + GJ and EH + FG) are equal, so KH and FJ need to be equal.

- SAS (Side + Angle + Side)

          FG + EH and KE + GJ are equal. We need to use the angle in between them to use SAS, so ∠KEH and ∠FGJ need to be equal.
