Answer:

vol. of triangular prism = lbh/2

vol. of rectangular prism = 18 of vol. of triangular prism

18x = 18 + 14x

4x = 18

x=4.5 ft

so vol. of rectangular prism = 6 × 4 . 5 × 3 = 81 ftcube

How many 3/4 pound packages can you make with 6.5 pounds of sunflower seeds?
xz_007 [3.2K]

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

Hope this helps!!

Please mark brainliest !

Amy is 9 years older than her younger sister. if her younger sister is now 1 year old, how many years later will Amy be 4 times
Sholpan [36]
<h3><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u></h3>

  • Age of Amy's younger sister=1year

☆Amy is 9 years older than her younger sister.

\\ \sf\longmapsto Age\:of\:Amy=1+9=10years

Let after x years Amy will be 4times old as her sister.

ATQ

\\ \sf\longmapsto \dfrac{1+x}{9+x}=\dfrac{1}{4}

  • Using cross multiplication

\\ \sf\longmapsto 4(1+x)=1(9+x)

\\ \sf\longmapsto 4+4x=9+x

\\ \sf\longmapsto 4x-x=9-4

\\ \sf\longmapsto 3x=5

\\ \sf\longmapsto x=\dfrac{5}{3}

\\ \sf\longmapsto x=1.6

\\ \sf\longmapsto x=2(approx)

Find the equation of the linear function represented by the table below in slope-intercept form.
ollegr [7]

Answer:

y = -3x-4

Step-by-step explanation:

First we find the slope

m = (y2-y1)/(x2-x1)

   = (-16 - -7)/(4-1)

   = (-16+7) /3

   = -9/3

  = -3

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -3x+b

Using a point

-10 = -3(2)+b

-10 = -6+b

-10+6 = b

-4 = b

y = -3x-4

Find the center and the radius of the circle with the equation:x^2+6x+y^2+4y+12=0
oksian1 [2.3K]

Answer:

The center is at (-3, -2) and the radius = 1.

Step-by-step explanation:

We can do this by converting the given equation to standard form.

x^2+6x+y^2+4y+12=0

x^2+6x+y^2+4y = -12

Completing the square on the x and y terms:

(x + 3)^2 - 9 + (y + 2)^2 - 4 = -12

(x + 3)^2 + ( y + 2)^2 = -12 + 9 + 4

(x + 3)^2 + ( y + 2)^2 = 1

So the center is (-3, -2) and the radius = 1.
