Answer:

Step-by-step explanation:

( 4 / 21 ) ( 7 / 16 ) ( 15 / 9 )

= ( 2 × 2 × 7 × 3 × 5 )/( 3 × 7 × 2 × 2 × 2 × 3 × 3 )

= ( 5 )/ ( 2 × 3 × 3 )

= 5 / 18

As an estimation we are told £3 is €4.

vova2212 [387]

Answer:

To solve the above problem we will use the unitary method as follows

As estimated If £ 3 is equivalent to € 4

Then, £ 1 will be equivalent to = € \frac{4}{3}

£ 64.60 will be equivalent to = € \frac{4}{3} \times 64.60 = 1.3333 \times 64.60 = 86.1311

Now you have to round the answer up to 2 decimal points to get the final answer

€ 86.1311 ≈ € 86.13

Thus, £ 64.60 is approximately equal to € 86.13.

Estimate the area of a circle with a radius of 21 meters. Use 22/7 for pi. (1 point)

V125BC [204]

A= $\pi$ $r^{2}$

A=( $\frac{22}{7}$ )( $21^{2}$ )

A=( $\frac{22}{7}$ )(441)

A= $\frac{22}{7}$ )( $\frac{441}{1}$ )

A= $\frac{9702}{7}$

A=1386 square meters

The answer is B.

What is the slope of the line that passes through these two points? (-3, 2) (4, 2)

Alik [6]

Answer: 0

Step-by-step explanation:

To find slope, I found that an easy way is the equation y2 - y1 over (divided by) x2 - x1

so for this, it would be:

$\frac{2 - 2}{4-(-3)}$

which is 0/7

0 divided by 7 is 0, so there is your answer
