Answer:

m<HGF = 45

Step-by-step explanation:

This picture shows an inscribed angle. It is made of 2 chords that connect on the vertex.

An inscribed angle is equal to half the arc. It is the arc that the angle makes. In this case it is the arc HF. So, to find the answer you would divide the length of arc HF by 2.

90/2=45

Eugenia walked all the way to school at 3 mph then realized she forgot her math book (how could she?!), so she ran back at 7 mph

kondor19780726 [428]

Let us say distance between Eugenia's home and school is x miles.

Speed of Eugenia when she walked from home to school = 3 mph

Speed of Eugenia when she walked from school to home = 7 mph

Total time taken = 45 minutes or 0.75 hours

We know that the speed distance formula is given by:

$speed=\frac{distance}{time}$

$time=\frac{distance}{speed}$

Time taken by Eugenia when she walked from home to school = x/3 hours

Time taken by Eugenia when she walked from school to home = x/7 hours

Total time taken = x/3+x/7

So forming an equation we have,

$\frac{x}{3}+\frac{x}{7}=0.75$

Taking lcd of 7 and 3 as 21,

$\frac{7x}{21}+\frac{3x}{21}=0.75$

$\frac{10x}{21}=0.75$

10x=15.75

Dividing both sides by 10 , we have

x= 1.575

Answer: So we can say that the distance between Eugenia's house and school is 1.575 miles.

navik [9.2K]

Answer:

11. 135 mph

12. 40 Oz

13. 50 m

14. 2500

15. 240

i don't know 16

Step-by-step explanation:

11. 27 x 5= 135 mph

12. 24 : 6 x 10= 40 Oz

13. 1.5 : 3 x 100= 50 m

14. 40% = 1000

10% = 250 (1000 : 4 = 250)

100%= 2500 (250 x 10 = 2500)

15. 75% -> 25% = : 3

180 : 3 = 60

180 + 60 = 240
