Find the area of the triangle
A)
B)
09
11 ft2
D)
224²

Answers

Answer:

A

Step-by-step explanation:

Area of a triangle = [tex]\frac{bh}{2}[/tex]

where b = base length and h = height

the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5

So area =

[tex]\frac{2\frac{1}{2} *4\frac{2}{5} }{2} \\\\2\frac{1}{2} *4\frac{2}{5} =11\\\\\frac{11}{2} =5.5[/tex]

5.5 also = [tex]5\frac{1}{2}[/tex]

Hence, the correct answer is A

2. Taking all known numbers to the other side:

        25x = 10 + 15 (taking a number over means you have to change the sign)

3. Solving the known side:

        25x = 25

4. Isolating the Variable:

Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?

Answers

Answer:

There are 25 students in the class.

Step-by-step explanation:

Let the total number of students in the class= x

No. of students who passed the test = 18 = 72% of x = 72x/100

Therefore, 72x/100=18

=72x=18*100=1800

=x=1800/72= 25 students.

Hence, total number of students in the class= 25 students

Answers

Answer:

x = 12

Step-by-step explanation:

The angles are supplementary and add up to 180

(8x - 20) + (8x + 8) = 180

Combine like terms

16x - 12 = 180

add 12 to both sides

16x = 192

Divide both sides by16

x = 12

A contruction company is working on a road which is 1/4 mile long. The workers divide the road into 3 equal sections. Brent claims that each section of road is 3/4 mile long.

Answers

Answer: Brent would be wrong because each section of the road is 1/12 mile long

Step-by-step explanation:

The road is 1/4 mile long. When divided into 3 equal parts, it is done in the following manner:

= 1/4 ÷ 3

= 1/4 * 1/3

= 1/12

Each section of the road is 1/12 of a mile long.

3/4 is actually a larger quantity than 1/4 so saying that each section was 3/4 of a mile would mean it was longer than the road itself which is not logical.

Answer:

  C)  65°

Step-by-step explanation:

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(?) = 25/59

  ? = arccos(25/59) ≈ 64.93°

The indicated angle is about 65°.

a. 38/98
b. 23/51
c. 47/98
d. 23/38

Answers

Answer: D 23/38

Step-by-step explanation:

Probability helps us to know the chances of an event occurring. The correct option is D, 23/38.

What is Probability?

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The value of P(C|N) is the ratio of the number of cats taking naps between 2:00 p.m and 2:30 p.m and the total number of cats.

Therefore, the value of P(C|N) is,

P(C|N) = P(C∩N)/P(C)

P(C|N) = 23/38
