Step-by-step explanation:

3b+8c=50c

3b=50c-8c

3b=42c

b=14c

So there are 14 cookies in each box.

Answer:

14

Step-by-step explanation:

First, take away the 8 cookies that were not part of the 3 boxes.

(50 - 8 = 42)

Now we know that 3 boxes of cookies can hold 42 total cookies. However, we need to know how much cookies 1 box can hold. If the 42 cookies are divided evenly between the 3 boxes, our equation would look like this:

42/3 = 14

Therefore, the answer is 14 cookies in each box.

x= 6 x= 1

Answer:

C

Step-by-step explanation:

(0,-4) (-4, -3)

-3- -4 / -4 -0 = 1/-4 is the slope

so is C

Answer:

The answer is B.

Step-by-step explanation:

slope-intercept form is y=mx + b with m being slope and b being y-intercept. slope is change in y over change in x, and in this situation the change in y is 1 and the change in x is 4. so, slope = 1/4. so now our equation is y=1/4x+b. now we have to find the y-intercept, which in this graph is -4. so, the equation is y=1/4x+-4. Hope this helps!

Answer:

See explanation

Step-by-step explanation:

Recall that all the sides of the square are equal

Hence;

Area of a rectangle= l * b ------- equation 1

Perimeter of a rectangle = 2(l + b)----------equation 2

Area of the rectangle = 140 square centimeters

140 = lb

l = 140/b

Perimeter of the rectangle =  54 centimeters

substituting l = 140/b into equation 2

54 = 2(140/b + b)

Multiplying through by b

54b = 280 + 2b^2

Hence;

2b^2 - 54b + 280 = 0

Solving the quadratic equation

b=20 or b=7

substituting b=20 or b=7 into l = 140/b

l = 140/20 or l = 140/7

l = 7 or 20

THEREFORE;

b=20 cm or b=7 cm

l = 7cm or 20cm

There is a time limit dude, googling is a faster way

1. Area of rectangle

A = l*z

2. Find z

93 = 13*z

z ≈ 7.15

Answer:

7km

Step-by-step explanation:

The given figure is a rectangle

The formula to find area of rectangle is,

[tex]l \times b[/tex]

Here,

Length = 13km

Area = 91 km^2

Then breadth = 91/13

= 7 km

Answer:

4

Step-by-step explanation:

slope is rise/run, rise is 4, while run is 1.

4/1=4, you'd write the slope as 4x in an equation, not sure if you're supposed to write it as 4 if it's just asking for the slope.

Answer:

J. 9

Step-by-step explanation:

First we have to plot the points (In the picture)

Now we have to count how close the are together which would make it 8.

And the closest to that would be 9.

Hope this helps :)

Answer:

Step-by-step explanation:

The distance between two points is

d^2=(x2-x1)^2+(y2-y1)^2

We have points (-4,-6) and (4,4) so

d^2=(-4-4)^2+(-6-4)^2

d^2=8^2+10^2

d^2=64+100

d^2=164

d=12.8

So H 13 units is closest to the distance between the two points.

Answer:

12

Step-by-step explanation:

Let's put the equations in standard form. For the first equation, we have:

−11y=6(z+1)-13y

2y−6z=6

y−3z=3

The second equation is:

4y−24=c(z−1)

4y−cz=24−c

If we multiply the first equation by 4, we get:

4y-12z=12

Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.

The correct value of c is 12.

Answer:

The value of b is either + 6 or -6

Step-by-step explanation:

Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x

mathematically, the discriminant can be calculated using the equation;

D = b^2 - 4ac

a represents the coefficient of x^2 which is 3

b represents the coefficient of x given as b

2 represents the last number

D is the discriminant = 12

So we have that;

12 = b^2 - 4(3)(2)

12 = b^2 - 24

b^2 = 24 + 12

b^2 = 36

b = √36

b = +6 or -6

Answer:

No

Step-by-step explanation:

From part (b)

If number who voted = 280

Number of voters who would have voted Geron:

35% * 280

0. 35 * 280 = 98 voters

40 people voted for others:

To check if estimate from. Part b is accurate :

10% voted for others

10% of estimated voters = 40

Let, number of estimated voters = x

0.1 * x = 40

0.1x = 40

x = 40/0.1

x = 400

If 40 people Voted others, the the number of voters should be 400 and not 280

Answer:

-21

Step-by-step explanation:

Given the sum of the first n term as;

Sn = 2 - 7n^2

The nth term is expressed as;

Tn = Sn - Sn-1

Sn-1 = 2 - 7(n-1)^2

Tn = 2 - 7n^2 - (2 - 7(n-1)^2)

Tn = -7n^2 + 7(n-1)^2

To get the second term, we will substitute n = 2 into the resulting expression

T2 = -7(2)^2 + 7(2-1)^2

T2 = -7(4)+7(1)^2

T2 = -28 + 7

T2 = -21

Hence the second term of the sequence is -21

Answer:A

Step-by-step explanation:

The exponential decay functions are y = 2(2/5)ˣ and y = 2(4/3)ˣ

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

We know,

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

And to find the y-intercept,

Substitute the value of x = 0 and solve for y.

Then y =2.

The functions are y = 2(2/5)ˣ and y = 2(4/3)ˣ

Therefore, the function are y = 2(2/5)ˣ and y = 2(4/3)ˣ.
