The costs of 1 kg apples and 1 kg grapes are in the ratio of 9:7. The cost of 1 kg apples is Rs 20 more than the cost of 1kg grapes. Find the cost of 1 kg apples and 1 kg of grapes.

Answers

Answer 1

Answer:

Apple = Rs90

Grape = Rs70

Step-by-step explanation:

Given

Represent Apples with A and Grapes with G

Such that:

The ratio is

[tex]A : G =9:7[/tex]

And the price is

[tex]A = 20 + G[/tex]

Required

Determine the cost of 1 kg of each fruit

[tex]A : G =9:7[/tex]

Convert to fraction

[tex]\frac{A}{G} = \frac{9}{7}[/tex]

Cross Multiply

[tex]7A = 9G[/tex]

Make A the subject

[tex]A = \frac{9}{7}G[/tex]

Substitute [tex]\frac{9}{7}G[/tex] for A in [tex]A = 20 + G[/tex]

[tex]\frac{9}{7}G = 20 + G[/tex]

Collect Like Terms

[tex]\frac{9}{7}G - G = 20[/tex]

Take LCM

[tex]\frac{9G - 7G}{7}= 20[/tex]

[tex]\frac{2G}{7}= 20[/tex]

Multiply through by 7

[tex]7 * \frac{2G}{7}= 20 * 7[/tex]

[tex]2G= 20 * 7[/tex]

Divide through by 2

[tex]\frac{2G}{2} = \frac{20 * 7}{2}[/tex]

[tex]G = \frac{20 * 7}{2}[/tex]

[tex]G = 10 * 7[/tex]

[tex]G = 70[/tex]

Substitute 70 for G in [tex]A = \frac{9}{7}G[/tex]

[tex]A = \frac{9}{7} * 70[/tex]

[tex]A = 9 * 10[/tex]

[tex]A = 90[/tex]

Answers

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line is y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope of the line using the points (1, 1) and (2, 4).

Slope = [tex]\frac{rise}{run}[/tex]

          = [tex]\frac{4-1}{2-1}[/tex]

          = 3

Based on the graph, the y-intercept is (-2) so the equation of the line is:

y = 3x - 2

The slope is y= 3x-2 is correcttt

Ana tiene ahorrados 30 €. Un fin de semana sale al cine con unos amigos y se gasta 7 €, le compra un regalo que le cuesta 12 € a una amiga y paga el billete de tren, que le supone 3 €. Si al llegar a casa su padre le da sus 15 € semanales, ¿cuánto le queda finalmente? (Plantear la solución como una única operación con enteros).

Answers

Answer:

A Ana le queda 23 €.

Step-by-step explanation:

La mejor estrategia para la resolución de este problema consiste en leer paso a paso y traducirlo en una serie de sumas y restas. Comenzamos:

1) Ana tiene ahorrados € 30:

[tex]x = 30\,EUR[/tex]

2) Un fin de semana sale al cine con unos amigos y se gasta € 7:

[tex]x = 30\,EUR-7\,EUR[/tex]

[tex]x = 23\,EUR[/tex]

3) Le compra un regalo que le cuesta € 12 a una amiga y paga el billete de tren, que le supone € 3:

[tex]x = 23\,EUR-12\,EUR-3\,EUR[/tex]

[tex]x = 8\,EUR[/tex]

4) Si al llegar a casa su padre le da sus € 15 semanales:

[tex]x = 8\,EUR + 15\,EUR[/tex]

[tex]x = 23\,EUR[/tex]

Si lo definimos como única operación con enteros, tenemos que:

[tex]x = 30\,EUR-7\,EUR-12\,EUR-3\,EUR+15\,EUR[/tex]

[tex]x = 23\,EUR[/tex]

A Ana le queda 23 €.

Answers

Answer:

48 Siamese cats were surveyed

Step-by-step explanation:

Let x represent the total number of surveyed Siamese cats.

Since 5/8 of the Siamese cat said that they didn't mind having a lap up water from a bowl , hence:

Number of cats who lapped = (5/8)x

Also, 3/16 admitted they would have preferred to use a straw:

Number of cats who used straw = (3/16)x

Taking into consideration that 39 of the Siamese cats gave one of those two answers:

(5/8)x + (3/16)x = 39

(13 / 16)x = 39

x = 39 * 16 / 13

x = 48

48 Siamese cats were surveyed

Answer:

A.) This system has no solutions.

Step-by-step explanation:

y = 1/2x + 4

-1/2x + y = -5

-1/2x + (1/2x + 4) = -5

4 = -5

The system has no solutions, if we graph it, we get that it has the same slope with two different y-intercepts, these two are parallel. These two points will never meet at a point.

Answer:

use the relationship between coefficients of a pair of linear equations for no solutions i.e. a1/a2 equal to b1/b2 not equal to c1/c2 .

Here, a is coefficient of x and b is coefficient of y and c is constant term in both equation but make sure that you put the values of a1,a2,b1,b2,c1 and c2 after converting both equation in the form ax+by+c=0 with proper sign and here y=1/2(x) +4 is equation 1 and other is equation 2

The y-intercept is -5.5 as per graph

Taking two random points from the graph to find the slope:

(-1, -6) and (1, -5)

Use slope formula: m = (y2 - y1)/(x2 - x1)

m = (-5 - (-6))/(1 - (-1)) = 0.5

The line in slope-intercept form is (y = mx + b)

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is a kite TSVU as shown in the image.

{ 1 } -

UT = ST = 20

Perimeter of ΔSUT will be -

P = ST + TU + SU

P = 20 + 16 + 16 + 20

P = 72

{ 2 } -

Perimeter of ΔSUV will be -

P = SV + SU + VU

38 + 26 + VU = 102

VU = 38

ΔSUV ≅ ΔRUV

RU = SR = 16

{ 3 } -

ΔSUV ≅ ΔRUV

SR = RU

4x - 1 = x + 8

4x - x = 8 + 1

3x = 9

x = 3

SU = SR + RU

SU = 4x - 1 + x + 8

SU = 12 - 1 + 3 + 8

SU = 22

S, and the number of years 71. Solve the
equation below for C.
C-S
De

Answers

Answer:

C = 71D + S

Step-by-step explanation:

The computation of the equation for C is as follows:

Given that

Yearly Depreciation = D

Cost = C

Salvage value = S

Number of years = 71

Based on the above information

The formula for the yearly depreciation i.e. D is

D = (C - S) ÷ 71

71D = C - S

71D + S = C

So, the equation would be

C = 71D + S

Each person in a certain group supports only one of the two candidates R and T. Of the people in the group, 45 percent support Candidate R and the rest support Candidate T. How many people in the group are in favor of a flat tax

Answers

Missing Information:

Of the people in the group who support Candidate R, 58 percent are in favor of flat tax Of the people in the group who support Candidate T, 22 are in favor of a flat tax.

Answer:

[tex]Total = 26.1\%N + 22[/tex]

Step-by-step explanation:

Given

[tex]R = 45\%[/tex] --  [tex]Percentage[/tex] [tex]of\ R[/tex] in the total population

[tex]Favor\ Flat\ Tax = 58\%[/tex] in group R

[tex]Favor\ Flat\ Tax = 22[/tex] in group T

Required

Determine the number of people that supports T

First, the proportion of those that supports flax rate in R needs to be calculated.

[tex]Proportion = 45\% * 58\%[/tex]

[tex]Proportion = 26.1\%[/tex]

So, those that favor flat tax rate in group R are:

[tex]Favor\ Flat\ Tax = 26.1\%N[/tex]

Where N represents the total population.

Total number of people that supports the flax tax rate is gotten by adding  people that support flat tax rate in each group.

[tex]Total = Group\ R + Group\ T[/tex]

[tex]Total = 26.1\%N + 22[/tex]
