Answer:

17. 49

18. 139

19. 131

Step-by-step explanation:

17. The question is asking for angle BEF. This angle is complementary to angle DEB, which means that when we add the two angles up, we get 90 degrees. Knowing this and knowing the value of angle DEB, we get 41 + BEF = 90. So we subtract 41 from both sides and we get BEF = 49.

18. The question is asking for angle CEB. We first get that CEF is 90 degrees because CED is a straight line, and DEF is 90 degrees, so CEF is also 90 degrees (90 + 90 = 180). CEB is just angle CEF and angle BEF added together and we have both. CEB = 90 + 49 = 139.

19. The question is asking for angle AEF. We first need to realize that angle AEC and DEB are equal. AEF is just equal to AEC + CEF, and now we have both. AEF = 41 + 90 = 131.

As you were organizing your closet you counted 20 shirts and 12 pairs of pants what was the pants to shirt ratio?
NISA [10]

Answer: 5 : 3

Step-by-step explanation:

The ratio of shirts to pants can be shown by putting the number if shirts and pants in the following manner:

Number of shirts       :        Number of pants

20                               :                   12

Then you have to take this to the lowest term. 4 is a factor of both numbers so when divided by 4 we get:

= 5 : 3

This is the ratio.

A truck can be rented from Company A for ​$70 a day plus ​$0.50 per mile. Company B charges ​$20 a day plus ​$0.60 per mile to r
r-ruslan [8.4K]

Answer:

The rental cost for Company A and Company B will be the same after 500 miles

Step-by-step explanation:

The total cost of renting a truck from Company A can be expressed as;

Total rental cost(Company A)=Cost per day+Total rate

where;

Cost per day=70

Total rate=rate per mile×number of miles (m)=(0.5×m)=0.5 m

replacing;

Total rental cost(Company A)=70+0.5 m...equation 1

2. The total cost of renting a truck from Company B can be expressed as;

Total rental cost(Company B)=Cost per day+Total rate

where;

Cost per day=20

Total rate=rate per mile×number of miles (m)=(0.6×m)=0.6 m

replacing;

Total rental cost(Company B)=20+0.6 m...equation 2

Equating equation 1 to equation 2

70+0.5 m=20+0.6 m

0.6 m-0.5 m=70-20

0.1 m=50

m=50/0.1

m=500 miles

The rental cost for Company A and Company B will be the same after 500 miles
