twenty of the students in Hannah's class, or 80% of the class, voted to have pizza for lunch every Wednesday. How many students
Igoryamba

Answer:

There are 25 students in Hannah's class.

Step-by-step explanation:

If 20 students in Hannah's class is 80% of the total amount of students, we can use a variable to figure out the total amount of students.

Let's say x is the total amount of students. We can use this equation to solve the problem:

20 = .8x

This is saying 20 equals 80% (.8 when you move the decimal 2 times) of x, or the total amount of students. Let's solve.

20 = .8x

Divide by .8

25 = x

There are 25 students in Hannah's class.

Issouf claims that the scale factor is 1/2. which statement about his claim is correct?
love history [14]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

CB'=C'B'=2

B'B=6

CB=CB'+B'B=2+4=6

The scale factor of a figure is

k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}

k=\frac{C'B'}{CB}

k=\frac{2}{6}

k=\frac{1}{3}

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.

. How long does it take hair to grow 8 inches?
Veronika [31]

First of all, I do not see the need for the very long pause before the question. It just makes people like me have a harder job answering. But ok, here we go.


On average, it will take 9–10 months for that growth to occur.

However, look at this answer to the question, and read it carefully before using the above as an answer.

The length of time it takes to go from shorter to longer hair depends on whether you're starting from a pixie cut or a bob, and whether you're aiming for ponytail length or Rapunzel locks. It also hinges on the condition of your hair, what kind of nutrition you're consuming, how often you're trimming and how much you're stressing out your tresses along the way. Start from the inside and work your way out to add inches to your hair length in the least amount of time.

Beauty begins on the inside, and long, lustrous locks are no exception. A diet balanced in fruits, vegetables, protein and calcium is a good start, but ask your doctor if adding a supplement is in order. Hair can benefit from iron, which helps oxygenate strands, and zinc, which also aids in growth. Biotin and other B-complex vitamins help plump up hair thickness while adding healthy shine. Vitamin D can help keep follicles on a regular growth schedule. Foods and vitamin supplements that feed the hair can also give skin and nails a boost for a complete healthy makeover.

For the second question:

If you would like to know how much a 93-pound person weighs on the Moon, you can calculate this using the following steps:


120 pounds on the Earth ... 20 pounds on the Moon

93 pounds on the Earth ... x pounds on the Moon = ?


120 * x = 20 * 93      /120

x = 20 * 93 / 120

x = 15.5 pounds on the Moon


The correct result would be 15.5 pounds on the Moon.

Students at a local high school travel to school by car, bus, and bicycle. 1/5 of the 825 students Tavel by car, 48% of the stud
dezoksy [38]

Answer:

198 students walk to the local high school

Step-by-step explanation:

Total number students = 825

1/5 of the students travel by car

48% of the students travel by bus

0.08 of the students travel by bicycle

To find the number of students who wal to school we have to find the exact number of students who travel to school by car, bus and bicycle and subtract the result from the total number of students

Students who travel by car = 1/5×825

= 165 students

Students who travel by bus = 48% × 825

= 48/100 × 825

= 12/25 × 825

= 396 students

Students who travel by bicycle = 0.08 × 825

= 66

So now we add the results fo the equations above and subtract it from the total number of students to get the number of students that walk to school

Students that walk to school = 825 - (165 + 396 + 66)

= 825 - 627

= 198 students

Therefore 198 students walk to the local high-school
