Hey there! :)

Answer:

133 pieces.

Step-by-step explanation:

If 7 pieces of cardstock sell for $3, we can set up a proportion to determine the amount of pieces bought in pieces/ money spent:

$\frac{7}{3} = \frac{x}{57}$

Cross multiply:

7 · 57 = 3 · x

399 = 3x

Divide both sides by 3:

x = 133 pieces. This is the amount of pieces bought.

In a right triangle abc, cd is an altitude, such that ad=bc. Find ac, if ab=3 cm, and cd= square root 2 cm.

Mashcka [7]

AC² + BC² = AB² AD² + CD² = AC²

BC² = AB² - AC² BC² + CD² = AC² (AD=BC is given)

BC² = AC² - CD²

AB² - AC² = AC² - CD² (both sides were = to BC²)

AB² + CD² = 2AC²

(3)² + (√2)² = 2AC² (AB=3 and CD=√2 were given)

9 + 2 = 2AC²

11 = 2AC²

$\frac{11}{2}$ = AC²

$\sqrt{\frac{11}{2} }$ = AC

$\frac{11\sqrt{2} }{2}$ = AC

A boat takes 2 hours to travel 15 miles upriver against the current. if the rate of the boat in still water is 12 miles per hour

OLga [1]

Answer:

4.5 mph or 9/2 mph

Step-by-step explanation:

Let x be the rate of the current

Formula: Distance = rate x time

where rate upstream =(12-x) and time =2 hours

15=(12-x)(2)

15=24–2x

2x=24–15

2x= 9

x=9/2=4.5 miles per hour (rate of current)

Is the point (3, 11) a solution for the linear equation 1/3x + y = 12? Explain.

PtichkaEL [24]

9514 1404 393

Answer:

yes

Step-by-step explanation:

The point is on the line.

The coordinate values satisfy the equation:

1/3x + y = 12

1/3(3) + 11 = 12 . . . substitute for x and y

1 + 11 = 12 . . . . . . . true

Any point that satisfies the equation is a solution. (3, 11) is a solution.
