Answer:

Step-by-step explanation:

Rounding to nearest tenth:

i) if number in 100th place is 5,6,7,8 or 9, then add 1 to number in the tenth place and after adding remove all the digits right to it.

EG: 4.567  = 4.6

ii) if number in 100th place is 0,1,2,3 or 4, then write down number in the tenth place as it is and then remove all the digits right to it.

Eg: 4.523 = 4.5

a) 0.32 = 0.3  (b) 3.87 = 3.9   (c)0.709 = 0.7

d) 12.75 = 12.8  (d)12.745 = 12.8   e) 645.059 = 645.1

John can play 12 songs on the guitar and he
nalin [4]

Answer:

8 weeks

Step-by-step explanation:

Let

w = number of weeks

John = 12 + w

Aiden = 4 + 2w

How many weeks (w) will it be before Aiden knows as many songs as John?

Equate both John and Aiden expression

John = Aiden

12 + w = 4 + 2w

Collect like terms

12 - 4 = 2w - w

8 = w

w = 8 weeks

It will take 8 weeks before Aiden knows as many songs as John

What is the perpendicular height of an oblique prism with a volume of 144 cubic units and an area of 24 square units
givi [52]

Answer:

Height of the oblique prism is 18 units.

Step-by-step explanation:

Volume of an oblique prism = \frac{1}{3}(\text{Area of the base})(\text{Perpendicular height})

Area of the base of this prism = 24 square units

And volume of the prism = 144 cubic units

By substituting these values in the formula,

144 = \frac{1}{3}(24)(h)

h = \frac{144\times 3}{24}

h = \frac{432}{24}

h = 18 units

Therefore, height of the oblique prism is 18 units.

The graph of the equation y = 3x − 4 is shown. What statement is true about every point on the graph? Math item stem image CLEAR
8090 [49]

Answer:

C. If you triple the x-coordinate and then subtract 4, you get the y-coordinate.

Step-by-step explanation:

We are given the graph of the equation y = 3x -4 as shown below.

Substituting x =3 in the equation gives us,

y = 3x - 4

i.e. y = 3 × 3 - 4

i.e. y = 9 - 4

i.e. y = 5

Thus, we get the point ( x,y ) = ( 3,5 ).

Here, x = 3 < 5 = y.

So, option A is not correct.

Also for ( 3,5 ), we have y = 5 = 3 + 2 = x + 2 i.e. y is not 3 less than x.

This shows that option B is also not correct.

If we put x = 0 in the equation, we get y = 3x -4 i.e y = -4.

Thus, both x and y co-ordinate do not have the same sign.

So, option D is wrong.

Hence, option C is correct i.e. we get the y-coordinate, when we triple the x-coordinate and then subtract 4.
