Answer» Answer: Q1. Which of the following groups contain only biodegradable items? a. Grass, flowers and leather b. Grass, wood and plastic c. Fruit peels, cake and lime juice d. Cake, wood and grass Solution: a) Grass, flowers and leather c) Fruit peels, cake and lime juice d) Cake, wood and grass Above all are the groups that contain only biodegradable items. Since plastic is not a biodegradable substance, that group cannot be considered as a biodegradable. Q2. Which of the following constitute a food-chain? a. Grass, wheat and mango b. Grass, goat and human c. Goat, cow and elephant d. Grass, FISH and goat Solution: b. Grass, goat and human Here, the goat is the producer, goat is the primary consumer and human is the secondary consumer. Q3. Which of the following are environment-friendly particles? a. Carrying cloth bags to put PURCHASES in while shopping b. Switching off unnecessary lights and fans c. Walking to school instead of getting your mother to drop you on her scooter d. All of the above Solution: d) All of the above Q4. What will happen if we kill all the organisms in ONE trophic level? Solution: If we kill all the organisms in one trophic level, the food supply to the next level will strop resulting in imbalance of the ecosystem. As a result animals in the higher levels will die making the growth of animals in the lower trophic level increase in an enormous way. All of this will affect the overall balance in the ecosystem. Q5. Will the impact of removing all the organisms in the trophic level be different for different trophic levels? Can the organisms of any trophic level be removed without causing any damage to the ecosystem? Solution: Yes, the impact of removing all the organisms in a trophic level will be different for different trophic levels. For example, if all the producers are removed, there is a chance of death or migration of the primary consumers which will upset the trophic levels. This is same for all the levels. Therefore, the removal of organisms at any level would upset the whole ecosystem as the food chain is disturbed. The survival of the higher level animals is COMPLETELY dependent on the animals at the lower levels. Q6. What is biological magnification? Will the levels of this magnification be different at different levels of the ecosystem? Solution: Biological magnification can be defined as the progressive increase in the concentration of non-biodegradable wastes in the food chain. As there is an increase in the magnification at the primary level of the ecosystems, all the other levels do get affected and the concentration may vary when compared to first level. Q7. What are the problems CAUSED by the non-biodegradable wastes that we generate? Solution: Following are the problems caused by the non-biodegradable wastes: These substances cannot be decomposed by the microorganisms. As the quantity increases, dumping becomes a problem. Non-biodegradable wastes like heavy metals may enter the food chain in the upper trophic levels. They may escape to the groundwater which causes soil infertility and disturbance in pH of the soil. Q8. If all the waste we generate is biodegradable, will this have no impact on the environment?

Answer» ANSWER: Let C.P. of the article be Rs. x. When S.P. is Rs. 1060, then PROFIT = 1060−x When S.P. is Rs. 950, then Loss = x−950 According to the GIVEN CONDITION, we have Profit =120%ofLoss ⇒ 1060−x= 100 120 ×(x−950) ⇒ 5(1060−x)=6(x−950) ⇒ 5300−5x=6x−5700 ⇒ 11x=11000. ⇒ x=1000. Desire S.P. = 100 120 ×1000= Rs. 1200.

Answer»

ANSWER:

Let C.P. of the article be Rs. x.

When S.P. is Rs. 1060, then PROFIT = 1060−x

When S.P. is Rs. 950, then Loss = x−950

According to the GIVEN CONDITION, we have

Profit =120%ofLoss

⇒ 1060−x=

100

120

×(x−950)

⇒ 5(1060−x)=6(x−950)

⇒ 5300−5x=6x−5700

⇒ 11x=11000.

⇒ x=1000.

Desire S.P. =

Answer»

Step-by-step EXPLANATION:

We know that AC= 74,BC=70.

angle ABC=90 ( therefore it is a right angled triangle )

By the Pythagoras THEOREM,

(AC)^2 = ( AB )^2 + (BC)^2

74^2. =. AB^2 + 70^2

5476. =. AB^2 + 4900

AB^2. =. 5476 - 4900

AB^2. =. 576

AB. =. √576

27.	The length of the base of isosceles triangle is 24 cm and the length of the leg is 20 cm. Determine the ratio in which center of the inscribed circle divides the altitude on the base.PLEASE ANSWER THIS QUESTION.I WILL MARK THEM AS BRAINLIEST.
Answer» Given :- The length of the base of isosceles triangle is 24 cm and the length of the leg is 20 cm. To Find :- Determine the ratio in which center of the inscribed circle DIVIDES the altitude on the base. ? Answer :- Since, the altitude of an isosceles triangle bisects the base . so, USING pythagoras theorem we get, → Altitude = √[(equal side)² - (Base/2)²] → Altitude = √[(20)² - (12)²] → Altitude = √(400 - 144) → Altitude = √(256) → Altitude = 16 cm . now, if we assume a as equal sides and B as base , → Inradius = (b/2)√[(2a - b)/(2a + b)] → Inradius = (24/2)√[(220 - 24)/(220 + 24)] → Inradius = 12√(16/64) → Inradius = 12 * (1/4) → Inradius = 3 cm . therefore, → Length of Altitude left after inradius = 16 - 3 = 13 cm . hence, center of the inscribed circle divides the altitude on the base in the ration 13 : 3.

The length of the base of isosceles triangle is 24 cm and the length of the leg is 20 cm. Determine the ratio in which center of the inscribed circle divides the altitude on the base.PLEASE ANSWER THIS QUESTION.I WILL MARK THEM AS BRAINLIEST.

Answer»

Given :- The length of the base of isosceles triangle is 24 cm and the length of the leg is 20 cm.

To Find :- Determine the ratio in which center of the inscribed circle DIVIDES the altitude on the base. ?

Answer :-

Since, the altitude of an isosceles triangle bisects the base .

so, USING pythagoras theorem we get,

→ Altitude = √[(equal side)² - (Base/2)²]

→ Altitude = √[(20)² - (12)²]

→ Altitude = √(400 - 144)

→ Altitude = √(256)

→ Altitude = 16 cm .

now, if we assume a as equal sides and B as base ,

→ Inradius = (b/2)√[(2a - b)/(2a + b)]

→ Inradius = (24/2)√[(2*20 - 24)/(2*20 + 24)]

→ Inradius = 12√(16/64)

→ Inradius = 12 * (1/4)

→ Inradius = 3 cm .

therefore,

→ Length of Altitude left after inradius = 16 - 3 = 13 cm .

hence, center of the inscribed circle divides the altitude on the base in the ration 13 : 3.

Find the gradient of a line and also find the gradient of the perpendicular line on the following line.y= 3x – 5

Answer»

EXPLANATION.

EQUATION of the line.

⇒ y = 3x - 5.

As we know that,

⇒ Gradient of line = slope of the line.

⇒ The line is in the FORM of : y = mx + c.

⇒ Gradient of line = 3.

⇒ Gradient of perpendicular line = b/a.

We can write equation as,

⇒ 3x - y - 5 = 0.

⇒ Gradient = b/a = -1/3.

MORE INFORMATION.

Equation of tangent.

Equation of tangent to the curve y = f(x) at P(x₁, y₁) is,

(y - y₁) = m(x - x₁).

(1) = The tangent at (x₁, y₁) is PARALLEL to x-axes = (dy/dx) = 0.

(2) = The tangent at (x₁, y₁) is parallel to y-axes = (dy/dx) = ∞.

(3) = The tangent lines makes EQUAL angles with the axes = (dy/dx) = ± 1.
