Harry and Terry are each told to calculate 8−(2+5)8−(2+5). Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2+58−2+5. If Harry's answer is HH and Terry's answer is TT, what is H−TH−T?

Answers

Harry's Answer:
8-(2+5)8-(2+5) = 8-(16+40)-(2+5) ⇒ 8 - 16 - 40 - 2 - 5 = -55

Terry's Answer:
8 - 2 + 58 - 2 + 5 = 67

H = -55
T = 67

H - TH - T

-55 - (67*-55) - 67 = -55 - (-3685) - 67 = -55 + 3685 - 67 = 3,563

A gold coin weigh 20 grams. If the coin contains gold,copper and tin and in the ratio 4:3:1 how much gold is there in the coin ? Explain ???????

Answers

If gold coin weigh 20 grams. If the coin contains gold,copper and tin and in the ratio 4:3:1 then 10gm of gold is present in coin.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

A gold coin weigh 20 grams

the coin contains gold, copper and tin and in the ratio 4:3:1

We need to find the amount of gold in the coin.

Now let us add the ratio.

4x+3x+x=20

8x=20

Divide both sides by 8.

x=2.5

The amount of gold in coin is 4x.

4(2.5)=10 gm

Hence, 10 gm of gold is present in 20 grams of coin.

#SPJ2
4 + 3 + 1 = 8
20 ÷ 8 = 2.5

since the ratio is 4:3:1 and gold being 4
4 × 2.5 =

10
10 grams

What’s the distance between (3,4) , (7,2)

Answers

Answer:

D= 4.47

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

D=√((y_2-y_1)^2+(x_2-x_1)^2)

 

Where

(x_1,y_1) = (3,4)

(x_2,y_2) = (7,2)

 

Replacing these values in the distance formula

D =√((7-3))^2+(2-4)^2)

D =√((4)^2+(-2)^2)

D =√(16+4)

D =√(20)

D= 4.47
