Answer:

76 jelly beans total

Step-by-step explanation

4 x 8 = 28

6 x 8 = 48

28 + 48 = 76

Answer:

495 ways

Step-by-step explanation:

Given that:

Total number of applicants (n) = 12

Required number (r) = 4

Using the combination formula :

nCr = n! / (n-r)!r!

12C4 = 12! / (12 - 4)!4!

12C4 = 12! / 8!4!

12C4 = (12*11*10*9) / 4*3*2*1

12C4 = 11880 / 24

= 495 ways

Answer:

b≤−6

here u go

Answer:

Step-by-step explanation:

To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.

We need to reverse the operation - 5.3, so we add 5.3.

-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3

-1.2b ≥ 7.2

We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.

Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.

-1.2b / -1.2 ≥ 7.2 / -1.2

b ≤ -6 (remember to reverse the sign!)

We now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.

-1.2(-8) - 5.3 ≥ 1.9

9.6 - 5.3 ≥ 1.9

4.3 ≥ 1.9 ✅

We can check again with -6, since this and all numbers smaller than it should be a solution set.

-1.2(-6) - 5.3 ≥ 1.9

7.2 - 5.3 ≥ 1.9

1.9 ≥ 1.9 ✅

Step-by-step explanation:

x-intercepts , when y=0 are

(-1,0) and (5,0)

Answer:

C

Step-by-step explanation:

The zeros are also known as x-intercepts so it is the points on the x axis.

For x-intercepts the y is 0 so it is (-1,0) and (5,0)

9514 1404 393

Answer:

  x² -11x +18 = (x -9)(x -2)

Step-by-step explanation:

The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.

  18 = (-1)(-18) = (-2)(-9) = (-3)(-6)

The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...

  x² -11x +18 = (x -9)(x -2)

Answer:

10

Step-by-step explanation:

Answer: The GCF of 60, 70, and 80 is 10.

Step-by-step explanation: If you think about it, the GCF is definitaly going to be 10. That is because you can multiply 10 to get 60, 70, and 80. There is no other number higher than 10 that can be multiplied by something to get all of these values.  

Answer:

Step-by-step explanation:

I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.

Answer:

(2,16)

Step-by-step explanation:

y=-x+18

y=8x

8x=-x+18

8x+x=9x

-x+x=0

9x=18

9x/9=x

18/9=2

x=2

y=8(2)

y=16

Answer:

(2,16)

Step-by-step explanation:

Step 1: Substitute -x+18 for y in y=8x:

-x+18=8x Add X to both sides

9x=18 Divide 9 by both sides

x=2

y=8(2)Plug in the new value for x(which is 2) into one of the equations

y=16

Answer:

Y= -3/2x-8

Step-by-step explanation:

Let n be rhe number of vertices in the polygon, then the sum of all interior angle is (n - 2) × 180°.

Number of sides in a heptagon = 7

So, n = 7

So,

the sum of the interior angles of a heptagon

= (7 - 2) × 180°

= 5 × 180°

= 900°

Answer:

900

Solve for y.

8x−4y=16

-4y = -8x + 16

y = (-8x + 16)/-4

y = (-8x)/-4 + (16/-4)

y = 2x - 4

We only need two points to graph linear equations.

Now let x be 0 and solve for y.

y = 2(0) - 4

y = -4

This leads to the point (0, -4).

We need another point.

Let y = 0 and solve for x.

0 = 2x - 4

4 = 2x

4/2 = x

2 = x

This leads to the point (2,0).

Plot these two points on the xy-plane and connect the points with a straight line.

I'll let you do that.

Answer:-12

Step-by-step explanation:

So if the equation is 5y+2x-z and the substitutions are x=4     y=-3      z=5 , all you have to do is replace each variable with its given numbers. Like so

5(-3)+2(4)-5

Now what you have to do is simplify

Negative times a positive is a negative

Negative times a negative is a positive

Positive times a positive is a positive

So....

-15+8-5

-20+8

-12

This is a simple substitution problem. Remember the basics of negatives and positives! Than you will be just fine! :D

Answer:

If you draw this out, you can see that total fence equation will be:

2L + 4W = 1200

Simplify, divide by 2

L + 2W = 600

L = (600-2W)

:

Area;

A = L*W

Substitute (600-2W) for L:

A = (600-2W)*W

A = -2W^2 + 600W; a quadratic equation

:

The dimension that will produce the greatest area will be the "axis of symmetry

which is: x = %28-b%29%2F%282a%29

:

In this equation a=-2, b=600

W = %28-600%29%2F%282%2A-2%29

W = %28-600%29%2F%28-4%29

W = +150 ft is the width

:

Find the length

L = 600 - 2(150)

L = 300 ft is the length

:

We can say the a field 300 by 150 gives he greatest area

:

This illustrated on a graph where y axis is the area and x axis is the width:
