Answer:

-122

Step-by-step explanation:

f(3) = 3³ + 14(3)² - 7(3) - 10

= 27 + 126 - 21 - 10

= - 122 is the remainder

Answer:

remainder = 122

Step-by-step explanation:

Using the remainder theorem to evaluate the remainder

Division by x - 3 , thus evaluate f(3) for remainder

f(3) = 3³ + 14(3)² - 7(3) - 10

= 27 + 126 - 21 - 10

= 122 ← remainder

7 3/9 - 2 4/9 =<br>11 3/4 - 5 1/4 =

jeka57 [31]

1.)

$7 \frac{3}{9} - 2 \frac{4}{9} \\ = \frac{66}{9} - \frac{22}{9} \\ = \frac{44}{9} \\ = 4 \frac{8}{9}$

2.)

$11 \frac{3}{4} - 5 \frac{1}{4} \\ = \frac{47}{4} - \frac{21}{4} \\ = \frac{26}{4} \\ = \frac{13}{2} \\ = 6 \frac{1}{2}$

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space

Tatiana [17]

The rate in

$\frac{ {m}^{3} }{ {m}^{2} } \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }$

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so, $100 \times 100 \times 100 \: {cm}^{3} \: in \: {m}^{3}$

To find what is the volume in cubic metres.

$\frac{250000}{10000000} = \frac{1}{4} = 0.25 \frac{ {m}^{3} }{ { m}^{2} }$

so, the rate is $0.25 \frac{ {m}^{3} }{ {m}^{2} }$

The ratio of the ages (in years) of three children is 2:4:5. The sum of their ages is 33. What is the age of each child?

pickupchik [31]

We have 2x + 4x + 5x = 33 so 11x = 33 and x 3.

The children are 6, 12 and 15
