Answer:

the equation is p=8m. x=24

Step-by-step explanation:

The value of p is 8 times greater than m. So 8 times greater than 3 is 24.

Answer:

3 hours on the city roads and 4 hours on the other roads

Step-by-step explanation:

580 (total miles driven) - 400 (4 hours of driving 100km/h) = 180 (miles left)

180 (miles left to drive) / 60 (km/h) = 3 (hours driven at the speed of 60km/h)

Answer: 20π/9 cm²

Step-by-step explanation:

Central angle is given as = 50°

We should note that for a complete circle to be made, it needs 360∘. Therefore, this is 50/360 = 5/36 of the area of a sector.

Area of the sector = 5/36 × πr².

= 5/16 × π × 4²

= 5/36 × π × 16

= 80π/36

= 20π/9 cm²

Answer:

D - 33.75

Step-by-step explanation:

If the rectangles are similar, then you can use this cheat:

Width:

9/4 = 2.25

2.25 is the scale factor between the two rectangles.

Using the new-found scale factor, you can do this:

15 x 2.25 = 33.75

This means the length on the second rectangle is 33.75 inches long.

Hoping this helps you! :)

Hello There!

So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle

So basically

∠XYZ=∠WXY+∠XWY

so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)

115-45=70 so ∠XWY=70

Answer:

?+45=115° sum of two interior angle of the triangle is equal to the exterior angle

<XWY=115-45=70

Answer:

1:16000

0.01:x

cross multiply

x=16000*0.01

x=160

The actual distance represented by 1 centimetre is 0.16 kilometres.

Given that, the scale on a map is 1:16000.

We need to find what is the actual distance represented by 1 centimetre.

A scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size.

Now, the scale on a map is 1:16000.

That is 1 centimeter in map = 16000 actual centimeters.

1 meter = 100 centimeters.

1 kilometer = 1000 meter.

So, 1 kilometer = 100000 centimeters.

Now, the actual distance=16000/100000=0.16 km

Therefore, the actual distance is 0.16 km.

Answer:

4 with a remainder of 4

Step-by-step explanation:

60 divided by 14 is 4 with a remainder of 4

The additional number of units required is 10 units.

Given that:

Total number of units needed = 60 units

Total number of units per case = 14

So, the total number of cases required=Number of units needed / number of units per case.

Number of cases required = 60/14 = 4.285 (this means that 5 cases are required as 4 cases won't be up to 60 units)

With 5 cases, we have exceeded the required units needed :

Additional units will be : (14×5) - 60

Additional units = 70 - 60 = 10 units

Therefore, the additional number of units required is 10 units.

[tex]x = \sqrt{ \frac{y + 7}{2} } + 1[/tex]

1) Just add 1 to both sides.

[tex]y = 2( {x}^{2} - 2x + 1) - 7[/tex]

1) Square both sides.

[tex] {x}^{2} - 2x + 1 = \frac{y + 7}{2} [/tex]

2) Multiply both sides by 2.

[tex]( {x}^{2} - 2x + 1) \times 2 = y + 7[/tex]

3) Regroup terms.

[tex]2( {x}^{2} - 2x + 1) = y + 7[/tex]

4) Subtract 7 from both sides.

[tex]2( {x}^{2} - 2x + 1) - 7 = y[/tex]

5) Switch sides.

[tex]y = 2( {x}^{2} - 2x + 1) - 7[/tex]

Therefor, the answer for Y is y = 2 ( x² - 2x + 1) -7.
