Ankit's father is five years older than three times of Ankit's age. 50 years old, then calculate the present age of Ankit

Answers

Step-by-step explanation:

Let,

Ankit's age = x

So, ankit's father's age = 3x + 5

Given,

Age of Ankit's father's age = 50

Therefore,

By the problem,

=> 3x + 5 = 50

=> 3x = 50 - 5

=> 3x = 45

[tex] = > x = \frac{45}{3} [/tex]

=> x = 15

Hence,

Present age of Ankit is 15 years (Ans)

Answers

Answer:

option b

Step-by-step explanation:

explaination is in picture

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x - 2 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Parallel lines have equal slopes , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, 5) into the partial equation

5 = - 1 + c ⇒ c = 5 + 1 = 6

y = - [tex]\frac{1}{2}[/tex] x + 6 ← equation of line

hillary is cycling across montana taking a 845 mile course . the first week she covered.320 miles. the second week she traveled another 350 miles. how many more miles does she have to travel to complete course?

Answers

Answer:

175 miles

Step-by-step explanation:

Hillary has travelled

320 + 350 = 670 miles

in the first two weeks.

Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.

670 + x = 845

And if we subtract 670 from both sides:

x = 845 - 670 = 175

175 miles

A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7

This is answer A.1188
B.1200
C.1220
D.1224​

Answers

Answer:

Hi there!

We've given with the base area and height. We know the formula for base area

Base area = πr²

154 = 22/7 × r²

154 × 7/22 = r²

49 = r²

√49 = r

7 = r

Now

TSA = 2πr(h + r)

TSA = 2 × 22/7 × 7(7 + 20)

TSA = 44(27)

TSA = 1188 cm²

PLEASE HELP MARK BRAINLIESTS!!!!

Answers

Answer:

x=15 y=3

Both (4x+10y) and (6x) equal 90 degrees, as angle 4x+10y is vertical to a 90 degree right angle, and angle 6x is directly  beneath the right angle, making it equivalent. To find x, you simply do 90/6, which is 15, meaning x=15. Now plug in that into 4x+10y=90, which will make it 60+10y=90. Subtract 60 from 90, and divide the difference, 30, by 10, giving you 3, thus showing that y=3. You can double check by plugging in the x and y values.

If s = 1/2(v + u)t,

First before replacing the variable let us rephrase the equation.

s = 1/2(v + u)t, can also be written as,

t/2(u + v)

Now replacing the variables,

5/2(6 + 20) = s

2.5 * 26 = s

hence,

s = 65m

Answer:

B. 65 m

Step-by-step explanation:

[tex]s = \frac{1}{2} (u + v)t \\ s = \frac{1}{2} (6 + 20)5 \\ s = \frac{1}{2} \times 26 \times 5 \\ s = 13 \times 5 \\ s = 65 \\ [/tex]

A piece of string is 28 cm long. It is used to from a square. (a) what is the length of each side of square? (b) what is the area of the square.?​

Answers

Answer:

7 cm and 49 cm²

Step-by-step explanation:

(a)

A square has 4 equal sides , then

28 cm ÷ 4 = 7 cm

The length of each side of the square is 7 cm

(b)

The area (A) of a square is

A = s² ( s is the side length ) , then

A = 7² = 49 cm²

Answer:

Step-by-step explanation:

Perimeter of square will be equal to the length of the  string

Perimeter of square = 28 cm

4*side = 28

Divide both sides by 4

Side = 28/4

Side = 7 cm

b) Area of square = side * side

                             = 7 * 7

                             =49 cm²

What is her balance now, that she owes her mom? excerpt from Of Plymouth Plantation by William BradfordAn Understanding with the Indians (1621)All this while the Indians came skulking about them, and would sometimes show themselves aloof off, but when any approached near them, they would run away. And once they stole away their tools where they had been at work and were gone to dinner. But about the 16th of March, a certain Indian came boldly amongst them and spoke to them in broken English, which they could well understand but marveled at it. At length they understood by discourse with him, that he was not of these parts, but belonged to the eastern parts where some English ships came to fish, with whom he was acquainted and could name sundry of them by their names, amongst whom he had got his language. He became profitable to them in acquainting them with many things concerning the state of the country in the east parts where he lived, which was afterwards profitable unto them; as also of the people here, of their names, number and strength, of their situation and distance from this place, and who was chief amongst them. His name was Samoset. He told them also of another Indian whose name was Squanto, a native of this place, who had been in England and could speak better English than himself.Being after some time of entertainment and gifts dismissed, a while after he came again, and five more with him, and they brought again all the tools that were stolen away before, and made way for the coming of their great Sachem, called Massasoit. Who, about four or five days after, came with the chief of his friends and other attendance, with the aforesaid Squanto. With whom, after friendly entertainment and some gifts given him, they made a peace with him (which hath now continued this 24 years) in these terms:That neither he nor any of his should injure or do hurt to any of their people.That if any of his did hurt to any of theirs, he should send the offender, that they might punish him.That if anything were taken away from any of theirs, he should cause it to be restored; and they should do the like to his.If any did unjustly war against him, they would aid him; if any did war against them, he should aid them.He should send to his neighbors confederates to certify them of this, that they might not wrong them, but might be likewise comprised in the conditions of peace.That when their men came to them, they should leave their bows and arrows behind them. After these things he returned to his place called Sowams, some 40 miles from this place, but Squanto continued with them and was their interpreter and was a special instrument sent of God for their good beyond their expectation. He directed them how to set their corn, where to take fish, and to procure other commodities, and was also their pilot to bring them to unknown places for their profit, and never left them till he died. He was a native of this place, and scarce any left alive besides himself. He was carried away with divers others by one Hunt, a master of a ship, who thought to sell them for slaves in Spain; but he got away for England and was entertained by a merchant in London, and employed to Newfoundland and other parts, and lastly brought hither into these parts by one Mr. Dermer, a gentleman employed by Sir Ferdinando Gorges and others for discovery and other designs in these parts.Readers can infer that Samosets visit to the community improves the relationship between the colony members and the Native Americans.Which detail from the passage best supports this inference? 1. He was a native of this place, and scarce any left alive besides himself.2. After these things he returned to his place called Sowams, some 40 miles from this place, but Squanto continued with them and was their interpreter3.
