please help me with maths !!!

A fish was at the river-bed at a certain time. After 5 minutes, the water level of the river rose
up 2.4 cm and the water level of the river rose up again 3½cm after 4 minutes. The moment, the fish was at 14.6 cm from the river-bed and 162 cm below water level of the river.

Calculate the original height, in cm, of the water level of the river.

Answers

Answer 1

Answer:

170.7 cm

Step-by-step explanation:

Let the original water level is x.

Use below equation to find its value:

x + 2.4 + 3 1/2 = 162 + 14.6x + 2.4 + 3.5 = 176.6x + 5.9 = 176.6x = 176.6 - 5.9x = 170.7 cm

Line d is parallel to line c in the figure below.

Parallel lines d and c are intersected by lines q and p to form 2 triangles. At lines d and p, the angle is 2, at d and q, the angle is 1, and at q and p the angle is 3. At lines c and q, the angle is 4, at p and c, the angle is 5, and the third angle is 6.

Which statements about the figure are true? Select three options.
Vertical angles prove that Angle 2 is congruent to angle 5.
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.
In the two similar triangles, Angle 2 and Angle 4 are corresponding angles.
The triangles are similar because corresponding sides are congruent.

Answers

Answer: In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.

8. If v2 = u2+2gs, find the value of s when v = 25,
u= 12 and g = 10.

Answers

Answer:

s = 24.05

Step-by-step explanation:

Given

v² = u² + 2gs ← substitute v = 25, u = 12, g = 10

25² = 12² + (2 × 10 × s)

625 = 144 + 20s ( subtract 144 from both sides )

481 = 20s ( divide both sides by 20 )

24.05 = s

The sum of two numbers is 147. The difference of the two numbers is 25.
What are the two numbers? Show your work.

Answers

86 and 61.

x + y = 147
x - y = 25

I always found second setting that second equation up was hardest. How do I know which one comes first? You just keep them in the same order as the first math equation.

So let’s solve for x in terms of y:
x - y = 25
x = 25 + y

Then substitute that into your first equation:
x + y = 147
(25 + y) + y = 147
2y = 122
y = 61

x = 25 + y = 25 + 61 = 86

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)

Answers

Answer:

the answer is A. y=2sin(1/2x)+1

Step-by-step explanation:

I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph

The function that matches the graph is y= 2 sin(1/2x) +1.

What is graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

let y = A sin ([tex]\omega[/tex]x + Ф)+ k

T= 4π, w= 2π/T = 1/2

Now, midline= 1/2( max + min)

=1/2(3-1)= 2/2

k=1

and, A= 3-1 = 2

So, y= 2 sin(1/2x + Ф) +1

as, Ф=0

So, y= 2 sin(1/2x) +1

Two numbers have these properties Both numbers are greater than 8 The HCF is 8 The LCM is 80 Find the two numbers

Answers

Answer:

10 and 64.

16 and 40

Step-by-step explanation:

The product of the two numbers is equal to the product of LCM and HCF

Number 1* Number 2= LCM * HCF

Number 1* Number 2= 8*80

Number 1* Number 2= 640

Both the numbers are greater than 8. Suppose one number is 10 then the other number will be 640 ÷ 10= 64

so the two numbers will be 10 and 64.

Similalrly the two numbers can also be 16 and 40 and like wise.

Any number greater than 8 dividing 640 will give the second number also.

Answers

Answer: 2/8
explanation: because 6/8 plus 2/8 = 8/8

Answer:

2/8 of the fifth graders are not in band

Step-by-step explanation:

To find how many fifth graders are not in band, subtract the # of fifth graders in band. Your difference is the amount of fifth graders that are not in band. To check your answer add 2/8 + 6/8 which should be equal to 8/8 or a whole ( 1 ).

Step-by-step explanation: all you have to do is 125% of 10 million and you get 12.5 million.

Answer:

40 million

Step-by-step explanation:

125% of x

125/100 * x = 1.25x

x+ 10 = 1.25x

(subtract x from both sides)

10 = 1.25x - x

10 = 0.25x

(divide both sides by 0.25)

10/0.25 = x

x= 40

Rabbit was one of the proudest animals, and he liked to show off his very long, furry tail. Fox grew tired of listening to Rabbit boast about his tail and decided to play a trick on him. 2One winter morning, Fox went to the lake where the animals liked to drink. The lake was frozen, so Fox cut a hole in the ice. Then, she tied a fish to her tail and dipped it into the chilly water. When Rabbit arrived at the lake, he wanted to know what was happening. 3Im fishing with my tail, Rabbit, announced Fox, displaying the fish. 4With my long, beautiful tail, I can certainly catch ten fish! bragged Rabbit. He cut into the ice and dipped his tail into the water. Overnight the water froze, and Rabbits tail became stuck. Fox laughed at Rabbit, who tugged so hard that his long tail popped off! 5And that is why rabbits have short tails. The Blue Ox Makes Lakes 6In America's pioneer days, Paul Bunyan was the biggest, strongest lumberjack ever to swing an ax. He could chop down a whole forest with one swing. He could eat four dozen eggs and a sack of potatoes each morning for breakfast. 7One winter, when the weather was so cold that the snow turned blue, Paul Bunyan found a baby ox nearly frozen in the ice. A big man like Paul Bunyan needed an ox to carry all the lumber he chopped. The lumberjack warmed the little ox by the fire, but he stayed as blue as the sky. Paul Bunyan named the animal Babe the Blue Ox. 8Babe grew as big as a house and carried the trees that Paul Bunyan chopped. He tricked the lumberjacks with heavy footsteps that shook the ground like earthquakes. As Babe the Blue Ox journeyed across the country, he left a trail of deep hoof prints. When those giant hoof prints filled with rain, they formed the thousand lakes of Minnesota. Qestion: How are the themes of these two stories similar?

In PES, monochromatic light is directed onto a sample, causing electrons to be emitted. The kinetic energy of the emitted electrons is measured.
