A farmer sells 8.8 kilograms of apples and pears at the farmer's market. 1 4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?

Answers

Answer: She sold 6.6kg of pears in the market.

Step-by-step explanation:

 Weight of apples and pears at the farmer's market.=8.8 kilograms

Weight of apples = 1/4

which is = 1/4 x 8.8kg = 2.2 kg

Weight of Pears =Weight of apples and pears - Weight of apples

= 8.8kg- 2.2kg

= 6.6kg

Judy made 3 pans of brownies for her friends. She cut each pan into 8 equal pieces. Her friends ate 20/8 of the brownies. What fraction of the brownies are left?

Answers

Answer:

13/6

Step-by-step explanation: 8 pieces in 3 pan give us a total of 8/24, then minus 20/8. The writing of this equation is:

20/8- 8/24 or 8/24- 20/8 (both are good)

The common denominator here is 24 since it can divide 8 and divide itself.

Since you have 24 as denominator, you'll have to reconvert the fractions above by diving 24 by their previous denominator and multiply it by their numerator:

(24/8) × 20= 60 (numerator of the 1st fraction)

(24/24) × 8=  8 (numerator of the 2nd fraction)

The new fractions are then

60/24 - 8/24= 52/24

We could stop there but since we could find an irrational fraction as an answer, why not do it

52/24 (both divided by 2)= 26/12

26/12 can still be divided so we keep going

26/12 (both divided by 2) = 13/6

13 is a prime number and therefore can be divided only by itself, and 6 cannot be divided by 13 without having a decimal answer.

13/6 is the final answer

Answer:

  yes

Step-by-step explanation:

The point is on the line.

The coordinate values satisfy the equation:

What s proportionality in mathematics?

If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.

If equivalent elements in two sequences have a constant product, also known as the coefficient of proportionality, then the two sequences are inversely proportional.

The shadow  of a 25 m tall flagpole casts is = 10 m.

Let  the height of the office  building = x m.

The  shadow  of a x m tall office  building is = 26 m.

From theory of directly  proportionality:

25 : 10 = x : 26

25/10 = x/26

x = (25/10)×26 = 65

Hence,  the height of the office building is 65 meter.

Answer:

TUA=123

Step-by-step explanation:

so first we find <TUS in terms of x

so 180-11x-2

178-11x

so now we can use the sum of a triangle's angles which is always 180 to find the angles in triangle TUS

178-11x+5x+10+58=180

178-6x=112

take 178 from both sides

-6x=-66

x=11

so we can do 11x11+2=TUA

TUA=123

Jada has a stand in the marketplace where she sells ground cumin. Her weekly expenses are $300, and she sells her cumin at a fixed price per kilogram. If she sells 120 kilograms of cumin, her weekly net profit is $600.

Answers

Answer:

Step-by-step explanation:

The net profit of the marketplace is the difference between the revenue and the expenses. The revenue is the product of number of kilograms sold and the price per kilogram.

                           Profit  = Revenue - Expenses

                           600 = 120x - 300

The value of x from the equation is 7.5. The answer therefore for the first question is $7.5. Then, the number of kilogram of cumin she needs to sell to cover the expenses is $300/$7.5 and that is equal to 40.

1.A five - layer of cake weighs half a kilogram per layer.In each layer,the cake is decorated with icing which weighs 15g.3 candles which weighs 100g each is added.What is the total weight in kilogram of the fully decorated cake?​

Answers

Answer:  2.815 kilograms

======================================================

Work Shown:

1 layer = 0.5 kg

5 layers = 5*(0.5 kg) = 2.5 kg

icing = 15 g = 15/1000 = 0.015 kg

1 candle = 100 g = 100/1000 = 0.1 kg

3 candles = 3*(0.1 kg) = 0.3 kg

------------------------

The five layers combine to 2.5 kg. On top of that we have 0.015 kg of icing, and then finally the three candles add 0.3 kg more weight.

The total weight is therefore: 2.5+0.015+0.3 = 2.815 kilograms
