gavin has 460 baseball players in his collection of baseball cards and 15% of the players are pitchers.how many pitchers are in gavins collection

Answers

Answer: 230 pitchers.

Step-by-step explanation:

Given: Gavin has baseball players in his collection of base ball cards = 460

Percent of players which are pitchers= 15%=0.15

The number of pitchers there are in Gavin's collection $0.15*460$

Therefore, the number of pitchers there are in Gavin's collection=230

Hence, there are 230 pitchers in Gavin's collection.

number of pitchers = 15/100 * 460 = 69

Judith drove h hours at a rate of 55 mi/h. She did not reach her goal of driving 385 miles for the day. How long did she drive? Write an inequality and then solve for h.

Answers

if she did not reach her goal then
miles she drove must be less than 385
or
miles she drove<385

so rate=55 miles per hour
so
miles driven=h times 55
subsitute
55 times h<385
divide both sides by 55
h<7
she drove less than 7 hours

inequality=55h<385
h<7

05.01)A scale drawing of a living room is shown below: A rectangle is shown. The length of the rectangle is labeled 3 inches. The width of the rectangle is labeled 5.5 inches. The scale is 1 to 30. What is the area of the actual living room in square feet? Round your answer to the nearest whole number.

Answers

Scale = 1:30
Length = (1 x 3):(30 x 3) = 3:90 (i.e. the actual length of the living room is 90 inches = 7.5 feet)
Width = (1 x 5.5):(30 x 5.5) = 5.5:165 (i.e. the actual width of the living room is 165 inches = 13.75 feet)
Area of the actual living room = length x width = 7.5 x 13.75 = 103.125
Therefore, area is approximately 103 square feet.

Answer:

103 sq. ft.
