Alexander correctly and said 44 out of 50 questions on his geography test. What percent of the questions did he answer incorrectly? Express your answer as a present and as a decimal

Answers

Answer 1

Answer: He answered 44/50 questions correctly, which as a percent is 88% and 100% (the total) minus 88% leaves you with 12% of the questions answered incorrectly. 12% as a decimal is 0.12

Answer 2

Answer: 44 divided by 50 ( 44/50 ) = .88. which .88 = 88%

If x is not equal to 0 then u/x + 5u/x - u/5x = what?

Answers

$(u)/(x)+(5u)/(x)-(u)/(5x)=(u+5u)/(x)-(u)/(5x)=(6u)/(x)-(u)/(5x)=(6u*5)/(x*5)-(u)/(5x)\n\n=(30u)/(5x)-(u)/(5x)=(30u-u)/(5x)=\boxed{(29u)/(5x)}$

$(u)/(x)+(5u)/(x)-(u)/(5x)=(5u)/(5x)+(25u)/(5x)-(u)/(5x)=(5u+25u-u)/(5x)=(29u)/(5x)$

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9. Write the division problem that Martin solved

Answers

Answer:

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$

Step-by-step explanation:

Consider the provided information.

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9.

As we know that the quotient of the number is a negative number.

Therefore, the sign of both numbers must be different,

Thus we can concluded he must select $(2)/(3)$ as one of the card, so that product is a negative number.

Let the selected card be x.

$(2)/(3) / x =(-16)/(9)\n\nx=(2)/(3)/(-16)/(9)\n\nx=(2)/(3)*(-9)/(16)\n\nx=(-3)/(8)$

Hence, the two cards should be $(2)/(3)$ and $(-3)/(8)$

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$
