QUESTION POSTED AT 14/12/2019 - 05:05 PM

On a test, 1 point is given for each correct answer and 1 point is deducted for each incorrect answer. On the test Harold answered 34 items correctly and 6 items incorrectly. What two numbers can be used to find Harold's total score

Forgive me if I'm wrong, but here goes:

On Harold's test, he scores 34 points for his correct answers, and -6 points for incorrect answers. He would have gotten 28 points, but that's not the question.

34 is the first number, and I believe the next one is -6. 
6 is negative because 1 point is deducted for each incorrect answer, which also means 1 point is subtracted for every incorrect answer. Because the question is asking for numbers and not an equation or expression, the subtraction is expressed as a negative symbol, hence negative six.

Hope I helped!

QUESTION POSTED AT 14/12/2019 - 04:36 PM

After the price of petroleum oil went up by 10%, a consumer reduced his oil consumption by the same percent. By what percent would his petroleum bill be changed? THE ANSWER IS NOT 10%.

Let's assign some random values to it, and say 1 unit of petroleum costs 100 bitcoins, because we all know bitcoins are the best currency :P

If the price goes up by 10%, it is now 100*1.1 = 110bitcoins for 1 unit.

However he's only getting 0.9 units now, so multiplying 110 by 0.9 gives us 99 bitcoins. His petroleum bill used to be 100 (which is why I picked 100 as it's easier), and now it is 99. Therefore his petroleum bill has reduced by 1%

What is the solution to the equation? 4x - 26 - 3x = 16 - 20 (I got my answer as 22, and that was correct, but I had completely forgotten how I did it. Help please)

Question:  4x - 26 - 3x = 16 - 20

Answer and Explanation:- 

First, we combine like terms.

4x - 3x = x

Now, rewrite the equation.

x - 26 = 16 - 20

16 - 20 = -4

x - 26 = -4
  
Apply the inverse operation.

x - 26 = -4
   +26    +26

x = 22

Final answer: x equals 22, so the solution is 22.

QUESTION POSTED AT 14/12/2019 - 04:20 PM

A circle has an area of 40 square meters. Which answer is closest to the measure of its diameter?

Answer: The correct answer is 7.12 m.

Step-by-step explanation:

The expression for the area of the circle is as follows;

A=\pi r^{2}

Here, A is the area of the circle and r is the radius of the circle.

Calculate the radius of the circle.

A=\pi r^{2}

Put A= 40 square meter and \pi=3.14.

40=(3.14) r^{2}

r=3.56 m

The expression for the diameter is as follows;

d= 2r

Here, d is the diameter of the circle and r is the radius of the circle.

Put r= 3.56 m.

d= 2(3.56)

d= 7.12 m

Therefore, the closest answer to the measure of the diameter of the circle is 7.12 m.

A circle has an area of 80 square centimeters. Which answer is closest to the measure of its radius?


There are no close answers, because you decided
not to list the choices at all.

The area of a circle is  (pi) x (radius²) .

So                                                 80  =  (pi)  (radius²)

Divide each side by pi :      Radius² = (80/pi)

Take the square root
of each side:                          Radius = √ (80/pi)

                                                             =  5.0463 cm (rounded)

A total of 60 students in Brooke's school are taking a spanish class this year. This is 25% more than the number of students who take a spanish class last year. Is the answer 45 or 48? Why?

Number of students taking Spanish class this year in Brooke's school = 60
Percentage increase in the number of students
taking Spanish class from last year = 25%
Then
Number of students that are taking Spanish
class more than last year = 25/100 * 60
                                          = 15
Then
The number of students that took Spanish class last year = 60 - 15
                                                                                             = 45 students
So the number of students that took Spanish class last year was 45. I hope the answer is clear to you and the procedure is also easy for you to understand.

A circle has a radius of 2.5 centimeters and a central angle AOB that measures 90°. What is the area of sector AOB? Use 3.14 for pi and round your answer to the nearest tenth. A. 2.9 cm2 B. 3.9 cm2 C. 4.9 cm2 D. 19.6 cm2


The area of any circle is        (pi) x (radius)²  .

The area of the WHOLE circle in the question is

                                                 (pi) x (2.5 cm)²

                                             =  (pi) x (6.25 cm²) .

The full circle is made by 360° of central angles.

90° of central angle makes a pie-wedge (sector)
that's exactly one fourth of the circle, so its area
is one fourth of the area of the whole circle.

                     Area = (1/4) (pi) (6.25 cm²)

                               = (0.25) (3.14) (6.25 cm²)

                               =    4.906 cm² .

Rounded to the nearest tenth:   4.9 cm² .

Garrett is 64 inches how many centimeters tall is he round your answer to the nearest tenth of a centimeter. 1 in.=2.54cm

To answer this we just need to convert by multiplying. Lets do it:-

1 in = 2.54 cm

64 × 2.54 = 162.56
64 in = 162.56 cm.  

To round 162.56 to the nearest tenth we will look at 162.56. Since this number is 5 we will round to the next number which will make it 162.60.

So, 64 in = 162.56 cm rounded to the nearest tenth is 162.60.
