First you turn the % in to decimal .20
then you multiply .20 by 340=68.00
then you subtract 340.00-68.00=272.00
the final answer is 272.00 pages

272 pages since you multiply .8 with 340(or 340 and .2 and subtract it from 340)

-12 + 4 3/5 = -7.4 <--- decimal.

-6 2/7 + 3 1/14 = 3 3/14 <--- repeating decimal.

-2 2/3 + -3 3/4 = -6 5/12 <--- repeating decimal.

How many students were surveyed about their mode of transportation to school?
AlekseyPX

Answer:

Total number of students surveyed about their mode of transportation to school is 400.

Step-by-step explanation:

Here, given student who uses car as their mode of transport = 120 students

We have to find the total number of students who are surveyed.

Also, since complete circle represents 100% of data,

Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.

Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%

Thus, percentage of students that uses car = 100 - 70 = 30%

Thus, 30 % of total students = 120

Mathematically,  30% of x = 120

Solving for x, we get,

\frac{30}{100} \times x=120

\Rightarrow x=120 \times \frac{100}{30}

\Rightarrow x=400

Thus, total number of students surveyed about their mode of transportation to school is 400.

How do i do this idk how to do
marysya [2.9K]

Let's find the perimeter first by adding all the side lengths together. There are two missing side lengths, which we can find by taking the side opposite them and subtract the side behind the missing side from them.

I've attached a diagram showing how to find the side lengths.

Now let's add all the side lengths together: 4 cm + 8 cm + 8 cm + 2 cm + 4 cm + 6 cm = 32 cm

The perimeter of this figure is 32 cm.

---

To find the area we can divide this figure into 2 rectangles. On the second attached diagram, I've split the figure into two and labeled the length and width of each rectangle.

Area of a rectangle = length * width

Area of red labeled rectangle = 4 cm * 2 cm = 8 cm²

Area of yellow labeled rectangle = 8 cm * 4 cm = 32 cm²

Add the two areas together: 8 + 32 = 40

The area of the figure is 40 cm².
