Answer 1
Answer:

Step-by-step explanation:

To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius. To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.

Explain how to estimate 368+231 two different ways

Answers

The two different ways of addition are mentioned above.

Given that,
To estimate 368+231 two different ways.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,


Here,
One way,
= 368 + 231
= 400 - 32 + 200 + 31
= 600 - 1
= 599

Second way
= 368 + 231
= 300 + 68 + 200 + 31
= 500 + 99
= 599

Thus, the two different ways of addition are mentioned above.

we know that

One very simple form of estimation is rounding.

To round off whole numbers:


Find the place value you want (the "rounding digit") and look to the digit just to the right of it.

If that digit is less than 5, do not change the "rounding digit" but change all digits to the right of the "rounding digit" to zero.

If that digit is greater than or equal to 5, add one to the rounding digit and change all digits to the right of the rounding digit to zero.

Part a) Estimate(368+231) rounding the numbers to nearest hundreds

368

368 > 350 ------> round up to 400

231

231 < 250 ------> round down to 200

so

(368+231)=400+200=600

therefore

the answer part a) is

600

Part b) Estimate (368+231) rounding the numbers to nearest tens

368

68 > 65 ------> round up to 370

231

31 < 35 ------> round down to 230

so

(368+231)=370+230=600

therefore

the answer part b) is

600

Given: circle k(O), m FH = (31x+3°) m GH = (33x+3°) m∠FHG = (28x−3°) Find: m∠FGH

Answers

Answer:

The measure of angle FGH is m∠FGH=48°

Step-by-step explanation:

step 1

Find the measure of arc FG in terms of x

we know that

The inscribed angle measures half that of the arc comprising

m∠FHG=(1/2)[arc FG]

substitute the given values

(28x−3°)=(1/2)[arc FG]

arc FG=(56x−6°)

step 2

Find the value of x

we know that

arc FG+arc FH+arc GH=360° -----> by complete circle

substitute the values

(56x−6°)+(31x+3°)+ (33x+3°)=360°

120x=360°

x=3°

step 3

Find the measure of angle m∠FGH

we know that

The inscribed angle measures half that of the arc comprising

m∠FGH=(1/2)[arc FH]

substitute the given values

m∠FGH=(1/2)[31x+3°]

m∠FGH=(1/2)[31(3)+3°]

m∠FGH=48°

Chetan and his 5 siblings buy a present for their mother on Mother's Day. As the eldest brother, he pays 0.2 of the cost of the present. The rest of the siblings share the balance equally. Each sibling pays $9.50 less than Chetan. What is the cost of the present.

Answers

Let's say that X is what the other 5 siblings pay. X + $9.50 is what Chetan pays. X + $9.50 is 1/5 of the cost of the present. To solve this we have to do 0.8 divided by 5 (the remaining cost split between 5 people) which is 0.16. Now from this we can learn that $9.50 is 0.04 of the cost of the present. A simple way to solve this is do 1.00 divided by 0.04 and then multiply $9.50 by that amount. 1.00 divided by 0.04 is 25 so $9.50 times 25 is $237.5.
The present costs $237.5

12 gallons of water fill a tank to 3/4 capicity. What is the capicity of the tank? If the tank is then filled to capicity, how many half-gallons bottles can be filled with the water in the tank?

Answers

Answer:

The total capacity of the tank  = 16 gallons

32 bottles can be filled with the water in the tank.

Step-by-step explanation:

Let the total capacity of the tank = K gallons

Now here, according to the question

3/4 capacity  of the tank = 12 gallons

⇒(3)/(4)  * K = 12\norK = 12 * (4)/(3)

or, K = 16 Gallons

So, the total capacity of the tank is 16 gallons.

Now, capacity of 1 bottle =  0.5 gallon= (1/2) gallon

So, number of bottles filled = Capacity of each bottle x Total capacity of tank

n = 0.5 gallon x 16 gallons = 32 bottles

Hence, 32 bottles can be filled with the water in the tank.
