Answer:

45/12

Step-by-step explanation:

first open the brackets +(-5½)= -5½

-7⅔-5½+8¾ put liketerms together

8¾-5½-7⅔

(find the LCM of the denominator 4,2,3 that is 12)

change the improper fraction to proper fraction 35/4-11/2-23/3.

(multiply by the 12 to make the denominator same)

(35/4x12)-(11/2x12)-(23/3x12)

<u>1</u><u>0</u><u>5</u><u>-</u><u>6</u><u>6</u><u>-</u><u>9</u><u>2</u><u> </u>= -53/12

A ball is thrown into the air with an upward velocity of 40 ft/s. Its height h in feet after t seconds is given by the function
goblinko [34]

Answer:

h=25

Step-by-step explanation:

From the question we are told that:

Velocity v=40fts

The height h function

 \large h=-16t^2+40t

Generally time t is mathematically given by

 h'=-32t+40

 -32t+40=0

 t=\frac{40}{32}

 t=1.25

Therefore  the ball's maximum height is given as

  \large h=-16(1.25)^2+40(1.25)

 \large h=-16(1.25)^2+40(1.25)

 h=25

Mary earns $25 per hour at her job. Next month, she will receive a 10% raise. Complete the two expressions that represent how mu
Natali5045456 [20]
25 + _0.10__*25

25 + __2.5___

In the 1st blank, the answer is 0.1 or 0.10 because you have to change percents to decimals to find the raise. 10% as a decimal = 0.1 or 0.10

In the 2nd blank, the answer is 2.5 because on the top, it's 0.1*25, which equals 2.5, and 2.5 is the raise. All you have to do is multiply 10%, or 0.1, by 25, and you get 2.5.

Hope this helped☺☺
