A car travels a distance of 350 km in a time of 5 hours.
What is the car's average speed?

I have added the complete question in the attachment

Answer:

15

Step-by-step explanation:

From the diagram in the attachment

27⁰ represents 3 pupils they love PE

135⁰ represents those that love mathematics. But the number was not given.

We have;

27⁰ = 3

135⁰ = ?

We cross multiply to find the unknown

135⁰x3 = 27⁰?

405 = 27⁰?

Divide through by 27

405/27 = ?

15 = ?

Therefore 15 pupils said mathematics was there favorite

Answer:

wrong it is b*h/2

Step-by-step explanation:

Answer:

Step-by-step explanation:

take 23 degree as reference angle

using tan rule

tan 23=opposite/adjacent

0.42=25/x

x=25/0.42

x=59.52

x=60

Answer:

The 3rd table

Step-by-step explanation:

The x values are dividing by 5 to  get the y values. The table is proportional because it's a pattern not just random values.

Answer:

A and B

Step-by-step explanation:

The answer for the question is A and B because 130+ 50=180 A line is equivalent to 180 degrees.B and C are opposites from each other so they are vertical.

Answer:

C)  x = 3

Step-by-step explanation:

factor out a 2 to get:

2(x² - 6x + 9) = 0

(x-3)² = 0

x = 3

Answer and Step-by-step explanation:

First, to find the zeros of the function, we can take out a common factor from the equation, and then factor.

The equation has a common factor of 2 (so distribute of the 2 from all of the numbers).

2([tex]x^2 - 6x + 9[/tex])

Now, we factor. Find two numbers that multiplies to [tex]9x^2[/tex] and adds up to -6x.

-3x and -3x.

Now, we substitute these two for -6x.

[tex]2(x^2 - 3x-3x+9)[/tex]

Factor.

[tex]2(x - 3)(x-3)[/tex]

Finally, we set all of the values to 0 and solve for x.

2 ≠ 0

x - 3 = 0    x = 3

x - 3 = 0    x = 3

That means the answer is C. x = 3

(Not shown, but the multiplicity of this x value is 2, because there are two

x = 3)

Answer:

6.4  cones full of water

Step-by-step explanation:

Given data

Radius of cone= 6inches

Slant height= 10 inches

Volume of cone= 1/3πr^2h

V= 1/3*3.142*6^2*10

V=  1/3*3.142*36*10

V=  1/3*1131.12

V= 377.04 cubic inches

Radius of right cylinder= 8 inches

Height= 12 inches

Volume of cylinder= πr^2h

Volume= 3.142*8^2*12

Volume= 3.142*64*12

Volume=2413.056 cubic inches

Hence the number of cone full of water needed to fill the cylinder is

=Volume of cylinder/volume of cone

=2413.056/377.04

=6.4  cones full of water

Answer:

x = 3 and y = 6

Step-by-step explanation:

The given equations are :

2x-y=0 ......(1)

3x-2y=-3 .....(2)

We need to solve equations (1) and (2).

Equation (1) can be written as :

2x = y

Put the value of y in equation (2)

3x-2(2x)=-3

3x-4x = -3

-x = -3

x = 3

Put the valye of x in equation (1)

2(3)-y=0

y = 6

Hence, the value of x = 3 and y = 6.

[tex]\huge\boxed{Answer\hookleftarrow}[/tex]

From the figure we can see that, [tex]\large\bold{3x°}[/tex] & [tex]\large\bold{x + 30°}[/tex] are vertically opposite angles.

⎆ Vertically opposite angles are equal to each other.

____________________

So, equation ⇻ [tex]\large\bold{3x° = x + 30°}[/tex]

____________________

Value of x will be :-

[tex]3x° = x + 30° \\ 3x - x = 30 \\ 2x = 30 \\ x = \frac{30}{2} \\ x = 15[/tex]

Answer:

Pythagorean theorem:

x^2 = 17^2 - 8^2

x^2 = 225

x = sqrt(225) = 15

The distance is 15 ft

Answer:

Solution given:

base=8ft

hypotenuse=17ft

perpendicular=?

By using Pythagoras law

hypotenuse ²=perpendicular ²+base²

17²=perpendicular ²+8²

perpendicular ²=17²-8²

perpendicular=[tex]\sqrt{225}=15[/tex]

Answer:

15

Step-by-step explanation:

9 squared + 12 squared = x squared

81 + 144 = x

81 + 144 = 225

the sqaure root of 225 = 15

Step-by-step explanation:

much. Write down the coordinates of the cross that you think represents this car on the graph

Answer:

D

Step-by-step explanation:

Using the sine ratio in the right triangle

sin51° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9}{y}[/tex] ( multiply both sides by y )

y × sin51° = 9 ( divide both sides by sin51° )

y = [tex]\frac{9}{sin51}[/tex] ≈ 11.6 ( to 1 dec. place ) → D

Answer:

Add 48 to get a perfect square

Explanation:

A perfect square would be of the number 651249 which means that you have to add 48 to get a perfect square.

Answer:

Step-by-step explanation:

since it's a square we know the two sides are equal.  So set them equal and solve for X

a)

4x + 3 = 3x +17

4x-3x = 17 -3

x = 14

Since we now know X  plug it into the expression for the angle

b)

5(14) + 4y = 90    ( 90°  b/c we know the angle is equal to that )

70 4y = 90

4y = 90-70

4y = 20

y = 20/4

y = 5

c)

we can find the perimeter by just plugging in X to either of the expressions for the side and then multiplying that by 4,  since there are 4 sides

4(14) +3

56 +3

59

now times 4 for each side

59*4= 236
