$20 is 10% is what he earned, and 10 is a factor of 100 (100 for 100%).
Since 10 x 10 is 100, we will also have to multiply 20 by 10: 200
Answer: $200 is what Barak earned by working in the pizza parlour.

Responder:

<h2>$ 150 </h2>

Explicación paso a paso:

Si inicialmente tengo $ 5 y mi madre me dio $ 10, el dinero total inicial que tengo será $ 5 + $ 10 = $ 15

Si mi papá me dio $ 30, mi tía y mi tío me dan $ 100, el monto recibido de mi tía y mi tío será de $ 30 + $ 100, es decir, $ 130

Como tengo otros $ 5 para todo este dinero, el dinero que realmente tengo será la suma total de todo el dinero recibido más mi dinero personal.

Dinero que realmente tengo = $ 15 + $ 130 + $ 5

= $ 150

4vir4ik [10]

Answer:

Cost\ of\ donut=\frac{49}{24}\approx \$2.042\\\\cost\ of\ donuts=\frac{49}{4}\approx \$12.25

Step-by-step explanation:

a.

Let\ cost\ of\ coffee=y\\\\cost\ of\ one\ donut=x\\\\Each\ friend\ buy\ one\ coffee\ and\ two\ donuts\\\\Amount\ for\ 1\ friend=Cost\ of\ coffee+2\times cost\ of\ donut\\\\Amount\ for\ 1\ friend=y+2x\\\\Amount\ required\ for\ 3\ friend=3\times Amount\ for\ 1\ friend\\\\Amount\ required\ for\ 3\ friend=3\times (y+2x)\\\\Amount\ required\ for\ 3\ friend=3y+6x\\\\Total\ bill=\$ 22\\\\3y+2x=22\\\\Given\ cost\ of\ coffee=\$3.25\\\\y=\$3.25

Hence\ solution\ of\ following\ system\ of\ equation\ will\ give\ cost\ of\ donut:\\\\3y+6x=22\\\\y=3.25\\\\\\Substitute\ y=3.25\ in\ first\ equation\\\\3\times 3.25+6x=22\\\\9.75+6x=22\\\\6x=22-9.75\\\\6x=12.25\\\\x=\frac{12.25}{6}\\\\x=\frac{49}{24}\approx \$2.042\\\\Cost\ of\ donut=\frac{49}{24}\approx \$2.042

See attached diagram.

b.

Each\ friend\ takes\ 2\ donuts\\\\Total\ donuts=Number\ of\ friends\times 2\\\\Total\ donuts=3\times 2=6\\\\cost\ of\ donuts=number\ of\ donuts\times cost\ of\ 1\ donut\\\\cost\ of\ donuts=6\times \frac{49}{24}\\\\cost\ of\ donuts=\frac{49}{4}\approx \$12.25

The diameter of a circle is 10 miles. what is the angle measure of an arc bounding a sector with area 5​ square miles?
Nataly [62]
Radius = 5 miles
Sector Area = (central angle / 360) * PI * radius^2
5 = (central angle / 360) * PI * 5^2
(central angle / 360) = 5 / (PI * 5*5)
(central angle / 360) = 1 / (PI * 5)
central angle = 360 / (PI * 5)
central angle = 72 / PI
central angle = <span> <span> <span> 22.9183118052 </span> </span> </span> degrees
