Answer:

The ratio of their areas 49:16

Step-by-step explanation:

The similarity ratio is 7:4. Therefore, the scale factor is k = 7/4

The scale factor of the area k^2 = 7^2/4^2

= 49/16

Hence, the ratio of their areas 49:16

Bryce has $16 more than Corey. Both have a combined total of $50. How much money does Bryce have.
LekaFEV [45]

Answer:

$33

Step-by-step explanation:

Let the amount of money Corey has be $x.

Amount of money Bryce have= $(x +16)

Total amount= $50

$x +$(x +16)= $50

2x +16= 50

2x= 50 -16

2x= 34

Divide both sides by 2:

x= 34 ÷2

x= 17

Amount of money Bryce have

= $(17 +16)

= $33

Iteru [2.4K]

Answer:

<h2>98 units</h2>

Solution,

Circumference of circle = 615.44 units

Radius = ?

Now,

Circumference of circle = 615.44

2\pi \: r = 615.44

2 \times 3.14 \times r = 615.44

6.28r = 615.44

r =  \frac{615.44}{6.28}

r = 98 \: units
