Think of the area divided into two parts.

A rectangle, 4.8 units by 9.6 units,

and a triangle with base 9.6 units and height 9 - 4.8 = 4.2 units.

Find the areas of the rectangle and triangle and add them.

Rectangle:

A = LW = 4.8 * 9.6 = 46.08

Triangle:

A = bh/2 = 9.6 * 4.2/2 = 20.16

Add the areas:

46.08 + 20.16 = 66.24

Answer: d. 66.2 units^2

If we slice this down the middle and fit it together like a puzzle we'll get a rectangle base 9.6/2 and height 4.8+9 so area (9.6/2)(4.8+9) = 66.24 square units.

Select all of the following that are ordered pairs of the given function.

podryga [215]

Answer:

(-1, 5)

(0, 3)

(2, -1)

Step-by-step explanation:

we have

$f(x)=3-2x$

Remember that

If a ordered pair is a solution of the given function, then the ordered pair must satisfy the given function

<u><em>Verify each case</em></u>

case a) (-2, -1)

substitute the value of x and the value of y in the given function and compare the result

$-1=3-2(-2)$

$-1=7$ ---> is not true

therefore

Is not a ordered pair of the given function

case b) (-1, 5)

substitute the value of x and the value of y in the given function and compare the result

$5=3-2(-1)$

$5=5$ ---> is true

therefore

Is a ordered pair of the given function

case c) (0, 3)

substitute the value of x and the value of y in the given function and compare the result

$3=3-2(0)$

$3=3$ ---> is true

therefore

Is a ordered pair of the given function

case d) (1,0)

substitute the value of x and the value of y in the given function and compare the result

$0=3-2(1)$

$0=1$ ---> is not true

therefore

Is not a ordered pair of the given function

case e) (2, -1)

substitute the value of x and the value of y in the given function and compare the result

$-1=3-2(2)$

$-1=-1$ ---> is true

therefore

Is a ordered pair of the given function

Lia, Phil, and Cam collect a total of 200.30 dollars for a holiday fundraiser. Phil collects 12.80 dollars more than Lia. Cam co

kramer

Answer:

Lia collects $ 37.5 , Phil collects $50.3 and Cam collects dollars $ 112.5 .

Step-by-step explanation:

Let us assume that the dollar collect by the Lia be x .

As given

Lia, Phil, and Cam collect a total of 200.30 dollars for a holiday fundraiser.

Phil collects 12.80 dollars more than Lia.

Phil collects dollars = 12.80 + x

As given

Cam collects 3 times as much as Lia.

Cam collects dollars = 3x

Than the equation becomes

x + 12.80 + x + 3x = 200.30

12.80 + 5x = 200.30

5x = 200.30 - 12.80

5x = 187.5

$x = \frac{187.5}{5}$

x = $ 37.5

Thus

Lia collects dollars = $ 37.5

Phil collects dollars = 12.80 + 37.5

= $50.3

Cam collects dollars = 3 × 37.5

= $ 112.5

Therefore the Lia collects $ 37.5 , Phil collects $50.3 and Cam collects dollars $ 112.5 .

Find the equation of the line The line has a slope of 1.3 and passes through the point (-2.3, -3.2)

irga5000 [103]

Answer:

y=1.3 x - 0.21

Step-by-step explanation:

$y = (slope) \times x + (constant)$

set (-2.3,-3.2) in above

$- 3.2 = 1.3 \times ( - 2.3) + c$

then c=-0.21
