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

Answer:

x=1

Step-by-step explanation:

hope this helps :)

Answer for :  5 (5x - 3) = 10

1. Opening the brackets:

       25x - 15 = 10

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:

       x = 25/25

5. Solving the equation:

       x = 1

Answer:

x = 4, y = 2

Step-by-step explanation:

3x - 2y = 8

-2y = -3x + 8

y = 3/2x - 4

2x + 4(3/2x - 4) = 16

2x + 6x - 16 = 16

8x = 32

x = 4  

3(4) - 2y = 8

12 - 2y = 8

-2y = -4

y = 2

Answer:

D:  y = 4x^2

Step-by-step explanation:

The graph for which the absolute value of the coefficient of x is largest has the narrowest graph.  That takes us immediately to D:  y = 4x^2.

Answer:

40 waves

Step-by-step explanation:

Prob (Mark catches waves) = Times waves caught / Total waves =  8 / 20 =  4 / 5 = 20%

Predicted waves out of 50 , caught = 4 / 5 or 20% of 50  = (4 / 5) x 50 = 40

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°.

_____

You can see that the figure is drawn approximately to scale and that the angle is more than 45°. (The unmarked leg is longer than the given leg.) The only answer choice that is more than 45° is the one shown above.

Answer:

y = (x+1)^2+5

Step-by-step explanation:

Add or subtract from both sides to complete the square;

y=x^2+2x+6; Subtract 5 from both sides

y-5 = x^2+2x+1; Factor;

y - 5 = (x+1)^2; Add 5 back to both sides;

y = (x+1)^2+5

Answer:

y=(x+1)²+5

Step-by-step explanation:

y=x^2+2x+6

a=1; b=2;c=6

subtract 6 from both sides: x^2+2x= -6

complete the square by using the equation (b/2)^2 and add to both sides: x^2+2x+1=-6+1

simplify: x^2+2x+1=-5

find the factors of 1 that add up to 2: 1 and 1

(x+1)(x+1)=-5

add 5 to both sides and simplify

y=(x+1)^2+5

My good sir will I lie to you

Given:

The figure and dimensions of the triangular prism.

The base is an isosceles triangle

To find:

The area of the triangular prism.

Solution:

The area of a triangle is:

[tex]A_1=\dfrac{1}{2}\times base\times height[/tex]

The base of the triangle is 24 cm and the height is 35 cm. So, the area of a triangular base (in sq. cm) is:

[tex]A_1=\dfrac{1}{2}\times 24\times 35[/tex]

[tex]A_1=12\times 35[/tex]

[tex]A_1=420[/tex]

The bases of the triangular prism are same. So, the area of the other triangular base is [tex]A_2=420[/tex] sq. cm.

The sides of the base triangle are 37 cm, 37 cm and 24 cm. So, the perimeter of the base triangle is:

[tex]P=37+37+24[/tex]

[tex]P=98[/tex]

Now, the curved surface area of the prism is:

[tex]A_3=P\times h[/tex]

Where, P is the base perimeter and h is the height of the prism.

The base perimeter of the triangular prism is 98 cm and the height is 48 cm. So, the curved surface area is:

[tex]A_3=98\times 48[/tex]

[tex]A_3=4704[/tex]

Now, the total  area of the triangular prism is:

[tex]A=A_1+A_2+A_3[/tex]

[tex]A=420+420+4704[/tex]

[tex]A=5544[/tex]

Therefore, the area of the given triangular prism is 5544 sq. cm.

Answer:

obtuse isosceles

Step-by-step explanation:

An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.

Answer:

No

Step-by-step explanation:

I don’t want to help you :)

We can use the Pythagorean Theorem to solve the triangle for x.

[tex]25^2=14^2+x^2[/tex]

[tex]625=196+x^2[/tex]

[tex]x^2=429[/tex]

[tex]x=\sqrt{429}[/tex]

x≈20.7

Answer: B.

[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]

Step-by-step explanation:

Let's solve your system by elimination.

4x−2y=8;−2x+2y=6

Add these equations to eliminate y:

   4x-2y=8  

 -2x+2y=6    

  2x=14

Substitute 7 for x in 4x−2y=8:  

(4)(7)−2y=8

−2y+28=8  (Simplify both sides of the equation)  

−2y+28+−28=8+−28  (Add -28 to both sides)

−2y=−20  

−2y/−2=−20/−2  (Divide both sides by -2)  

y=10
