Answer:

$Length=12 \ units\\Width=3 \ units\\\\\\Area=36\ units^2$

Step-by-step explanation:

-In a rectangle, the greater dimension is usually dimension is the length and the smaller dimension is the width.

Hence, Emma's rectangle is 12 \ units long and 3 Units wide.

-We the apply the area formula to find the area of her rectangle as:

$Area=Length\times width\\\\=12\times 3\\\\=36\ units^2$

Hence, the rectangle has an area of 36 sq units

Tania has a set of nesting rings. This table shows the relationship between the radius of a ring and the ring's circumference.

valentinak56 [21]

Answer:

The circumference is 59.66 cm

Step-by-step explanation:

we know that

The circumference of a circle (ring) is given by the formula

$C=2\pi r$

If the radius is

$r=9.5\ cm$

substitute in the formula

$C=2\pi (9.5)$

$C=19\pi\ cm$ ----> exact value

assume

$\pi =3.14$

substitute

$C=19(3.14)=59.66\ cm$

"Nathan takes 42 minutes to thread a distance of 4.5 miles on a threadmill. Determine the average distance covered in one minute

Viefleur [7K]

Solution:

we are given that

Nathan takes 42 minutes to thread a distance of 4.5 miles on a threadmill.

we have been asked to find the average distance covered in one minute.

Using the concept of unity we can write

Since Nathan takes 42 minutes to cover a distance of 4.5 miles.

So in 1 minute Nathan will cover a distance of $=\frac{4.5}{42} =1.07142miles$

Hence avearge distance covered in one minute is 1.1 miles.

In circle O, what is m∠MAJ?

ira [324]

we know that

The measure of the interior angle is the half-sum of the arcs comprising it and its opposite.

Find the measure of the angle LAM

m∠LAM is equal to

$\frac{1}{2}*[arc\ KJ+arc\ LM]= \frac{1}{2}*[170+80]\\\\=125\ degrees$

Find the measure of the angle MAJ

we know that

m∠LAM+m∠MAJ= $180$ ° ------> by supplementary angles

m∠MAJ= $(180-125)$

m∠MAJ= $55$ °

therefore

the answer is

The measure of the angle MAJ is $55\ degrees$

The steps below show the work of a student used to calculate the number of yards in 804.5 meters.

Butoxors [25]

Answer:

see below

Step-by-step explanation:

804.5 meters. to yards

Step 1:

(1 mile = 1,609 meters)

(1 mile = 1,760 yards)

1,609 meters is being multiplied by conversion factor 1 mile over 804.5 meters equals 2 miles

1,609 meter  x  1 mile  = 2 miles

804.5 meters

Step 2:

(1 mile = 1,609 meters)

(1 mile = 1,760 yards)

2 miles is being multiplied by conversion factor 1760 yards over 1 mile equals 3,520 yards

2 miles x  1,760 yards  = 3,520 yards

1 mile

no need of step 3. the conversion below should be on step 2.

to convert miles into yards.

(1 mile = 1,609 meters)

(1 mile = 1,760 yards)

Ella takes 1 3/5 hours to complete a painting. Holly takes 3/4 of the time that Ella takes. How long will Holly take to complete

Misha Larkins [42]

1. you have to figure out what 3/4 of Ella's time is.
$1 \frac{3}{5} = \frac{8}{5}$
(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)
$\frac{8}{5} = 8 \div 5 = 1.6$
$\frac{3}{4} = 3 \div 4 = .75$
3. Next you are going to divide 1.6 by .75
$1.6 \div .75 = 2.13$
4. Now multiple 2.13 by 5.
$2.13 \times 5 = 10.65$
Answer is 10
