Answer:

One pound of jelly  beans and one pound of gummy  worms candy cost $6 each

Step-by-step explanation:

Given

Let

[tex]J \to[/tex] Jelly Beans

[tex]G \to[/tex] Gummy worms

So, we have:

Brook

[tex]J + 6G = 42[/tex]

Ken

[tex]5J + 4G = 54[/tex]

Make J the subject in the first equation

[tex]J + 6G = 42[/tex]

[tex]J = 42 - 6G[/tex]

Substitute [tex]J = 42 - 6G[/tex] in [tex]5J + 4G = 54[/tex]

[tex]5*[42 - 6G] + 4G = 54[/tex]

Open bracket

[tex]210 - 30G + 4G = 54[/tex]

[tex]210 -26G = 54[/tex]

Collect like terms

[tex]-26G = 54 - 210\\[/tex]

[tex]-26G = -156[/tex]

Divide both sides by -26

[tex]G = 6[/tex]

Substitute [tex]G = 6[/tex] in [tex]J = 42 - 6G[/tex]

[tex]J = 42 - 6*6[/tex]

[tex]J = 42-36[/tex]

[tex]J = 6[/tex]

Step-by-step explanation:

Perimeter includes three sides of rectangle:

15m + 12m + 15m

Plus half of circle with diameter 12m

Circumference = diameter * PI

Circumference = 37.68m.

1/2 circumference = 18.84m

Total perimeter is 15m+12m+15m+18.84m

60.84m

Answer:

hence the long-term prediction for each major ; [ 1 , 1 ]

Step-by-step explanation:

Probability of A humanities major changes to Science = 0.9

P( science major changes to humanities ) = 0.2

Determine the long term predictions for each Major

The Transition matrix can be written as

[tex]\left[\begin{array}{ccc}0.1&0.9&\\0.8&0.2&\\\end{array}\right][/tex]

Find the equilibrium matrix p' of the Transition matrix above by finding the values of p, p^2 , p^3 ......... until any row of the resultant matrix

The eigen ( equilibrium ) vectors of the matrix

[tex]\left[\begin{array}{ccc}1&-1.125&\\1&1&\\\end{array}\right][/tex]

hence the long-term prediction for each major ; [ 1 , 1 ]

Step-by-step explanation:

LN = 4 + x - 8 = x - 4

LS = 3 + x - 5 = x - 2

By intersecting secants theorem:

[tex]LM\times LN = LK\times LS \\ \\ 4(x - 4) = 3(x - 2) \\ \\ 4x - 16 = 3x - 6 \\ \\ 4x - 3x = 16 - 6 \\ \\ x = 10[/tex]

Answer:

∠QRS = 35°

∠Q = 116°

Step-by-step explanation:

∠QRS and ∠QRT are supplementary angles

Supplementary angles add up to equal 180

Thus, 145° + ∠QRS = 180

180 - 145 = 35

145 - 145 cancels out

we're left with ∠QRS = 35°

In order to find the measure of ∠Q

We must find y

We have already identified that ∠QRS = 35°

Which means that we can find y by using the triangle angles rule which states that all angles in a triangle add up to equal 180

So 180 = y + 4y + 35

now we solve for y

step 1 combine like terms

y + 4y = 5y

we now have 180 = 5y + 35

step 2 subtract 35 from each side

180 - 35 = 145

35 - 35 cancels out

now we have 145 = 5y

step 3 divide each side by 5

5y / 5 = y

145 / 5 = 29

We're left with y = 29

Now we can find ∠Q

To do this we substitute y for 29

∠Q = 4(29)

4 * 29 = 116

Hence ∠Q = 116

Answer:

145=4y+y { exterior angle of triangle is equal to the sum of its opposite interior angle}

measure of / Q =4y =4×29=116°

Answer:

$190 Dollars she pay in interest

If we start with a circle with a marked radius line, and turn the circle a bit, the area marked off looks something like a wedge of pie or a slice of pizza; this is called a "sector" of the circle, and the sector looks like the green portion of this picture:

circle with central angle "θ" and radius "r" marked, delineating the sector, which is shaded a light green

The angle marked off by the original and final locations of the radius line (that is, the angle at the center of the pie / pizza) is the "subtended" angle of the sector. This angle can also be referred to as the "central" angle of the sector. In the picture above, the central angle is labelled as "θ" (which is pronounced as "THAY-tuh").

Answer:

Width=12 inches

Length=15 inches

Step-by-step explanation:

Let's say the width is x.

Then, the length is x+3.

The area of a rectangle is the length times width, so

x(x+3)=180

x^2+3x=180

x^2+3x-180=0

After using the quadratic formula, x comes out to be 12 or -15.

x cannot be -15 because you can't have negative distance, so we are left with x=12.

The width is 12 inches and the length is 12+3=15 inches.

Check: 12*15=180

Answer:

The width is 12 and the length is 15.

Step-by-step explanation:

You set the equation as x is equal to the width and since the lenght is 3 units longer than the width, it can be seen as "x + 3"

[tex]Area=(Length)(Width)[/tex]

180= x × (x + 3)

Then from there you just solve for x.

Answer:

  8)  42 in²

  9)  33 cm²

  10)  112 yd²

Step-by-step explanation:

8) The area is given by the formula ...

  A = 1/2(b1 +b2)h

  A = (1/2)(9 in +5 in)(6 in) = 42 in²

__

9) The area is half the product of the lengths of the diagonals.*

  A = 1/2(d1)(d2)

  A = 1/2(6 cm)(11 cm) = 33 cm²

__

10) As in the previous problem, ...

  A = 1/2(14 yd)(16 yd) = 112 yd²

_____

* This formula works for any quadrilateral with perpendicular diagonals.
