Answer:

t = \frac{D-M}{Mr}

Step-by-step explanation:

Given

D = M + Mrt ( subtract M from both sides )

D - M = Mrt ( divide both sides by Mr )

\frac{D-M}{Mr} = t

Answer:

t = D/Mr - 1/r or (D - M)/Mr

Step-by-step explanation:

D = M + Mrt

isolate t

D - M = Mrt

(D - M)/M = rt

D/M - 1 = rt

D/Mr - 1/r = t

AnnZ [28]

Answer:

3:2

Step-by-step explanation:

Ewen has 48 white tiles and 16 blue tiles

The cost of each white tile was £2

The cost of each blue tile was £4

Therefore the total cost of 48 white tiles is

= 48×2

= £96

The total cost of 16 blue tiles is

= 16×4

= £64

The ratio of the total cost of the white tiles and blue tile can be calculated by dividing the cost of both tiles by their greatest common factor

The greatest common factor of £96 and £64 is 32

96/32 = 3

64/32= 2

Ratio= 3:2

Hence the ratio of the total cost of the white tiles to the blue tiles is 3:2

Hunter started with the following model to show the problem 1 . 45 ÷ 5 1 . 45 ÷ 5 . One 10 by 10 flat, 4 rods of 10 cubes , and
vlada-n [284]

The model Hunter uses makes the division possible given that each

number of digits in a place value are represented by a cube.

  • The number of hundredth in each division group is <u>D. 9</u>

Reasons:

The model Hunter started to show the problem is as follows;

Number of 10 by 10 flat = 1

Number of rods of 10 cubes = 4

Number of single cubes = 5

The division is 1.45 ÷ 5, which can be expressed as follows;

\displaystyle \frac{1.45}{5}

Given that the 5 cubes represent the .05 in 1.45, we have;

1 cube = 0.01

Dividing each of the set by 5 gives, for each of the division group;

10 by 10 flat ÷ 5 = 10 × 2 flat = 20 cubes = 20 × 0.01 = 0.2

4 rods × 10 cubes ÷ 5 = 40 cubes ÷ 5 = 8 cubes = 8 × 0.01 = 0.08

5 cubes ÷ 5 = 1 cube = 1 × 0.01 = 0.01

Therefore, each of the division group is 0.2 + 0.08 + 0.01 = 0.29

<em>The </em><em>tenths </em><em>are the </em><em>digits </em><em>after the </em><em>decimal point </em><em>to the </em><em>right</em><em>.</em>

<em />

The hundredths are the digits in the second position after the decimal point to the right.

<em>The </em><em>number </em><em>of </em><em>tenths</em><em> in each group, </em><em>(0.2)</em><em> = 2</em>

<em>There are 2 tenths in each group</em>

The number of hundredths in each group, (0.09) = 9

There are 9 hundredths in each group.

Therefore;

The correct response to the question on how many hundredths would be there in each of the division groups is <u>D. 9</u>

DanielleElmas [232]

Answer:

so x = 4 and x = -2/3

Step-by-step explanation:

Solve for x using the Master Product:

3x^2-10x-8=0

we see   3*(-8) = -24   and  2 * (-12) = -24   and  2 + -12 = -10

so   3x^2  + 2x  -  12x  - 8 = 0

x (3x + 2) -4 (3x + 2) = 0

(x - 4)(3x + 2) = 0

so x = 4 and x = -2/3
