I REALLY NEED HELP!!! what is the answer to this one?

Answer: x=2 y=4

Step-by-step explanation: elimination method attached below.

Answer:

Pizza 1: lenght(l)=16 and width(w)=4

Perimeter=40in.

Pizza 2: l=32 and w=2

Perimeter=68in.

Step-by-step explanation:

1. List down factors of 64.

64=1,2,4,8,16,32,64

2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.

3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.

4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)

Pizza 1: Perimeter=2(16+4)

=2×20

=40in.

Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.

So, [tex]1000/16=\boxed{62.5}[/tex].

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.

So, [tex]400/8=\boxed{50}[/tex]

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.

So, [tex]300/4=\boxed{75}[/tex].

4)

The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.

Answer:  See the worksheet below. Hope you can see.

Step-by-step explanation:

Roots: where the parabola intersects the x-axis

Axis of symmetry: the line that runs along the vertex of the parabola

Vertex: the points at which the parabola changes direction

Intercept: the point where the line intersects the y axis

Domain: the values of x (lowest to highest)

Range: the values of y (lowest to highest)

Answer:

11/15

Step-by-step explanation:

Answer:

- 11 / 15

Step-by-step explanation:

x = - 2

y = - 1 / 5

1 / 3 + x . z

= 1 / 3 + ( - 2 ) . ( - 1 / 5 )

= 1 / 3 + ( - 2 . - 1 ) / 5

= 1 / 3 + 2 / 5

1 / 3

= ( 1 / 3 ) x ( 5 / 5 )

= ( 1 x 5 ) / ( 3 x 5 )

= 5 / 15

2 / 5

= ( 2 / 5 ) x ( 3 / 3 )

= ( 2 x 3 ) / ( 5 x 3 )

= 6 / 15

1 / 3 + 2 / 5

= 5 / 15 + 6 / 15

= ( 5 + 6 ) / 15

= 11 / 15

Answer:

C The car accelerated for 6 seconds and continued at a constant speed

Answer:

x = 15

Step-by-step explanation:

3x + 14 = 59

subtract 14 from both sides

3x = 45

divide both sides by 3

x = 15

Answer:

15

Step-by-step explanation

Subtract 14 from both sides and the do 45 divided by 3 and it gives you your answer 15

Answer:

f = 29

Step-by-step explanation:

First look at the angle inside the triangle that has no marker.  You can determine this angle using the angle on the opposite side (112).

A straight line will equal 180.  So this angle would equal 180 - 112 or 68.

Now you know two of the triangles angles....  53 and 68.

A triangle's inside angles always add up to 180 degrees.

53 + 68 = 121

The angle that is 2f + 1 must equal 180 - 121 which is 59 degrees.

2f + 1 = 59

2f = 58

f = 29

The three angles inside the triangle are 53, 68 and 59

Amy because Ben spend the less money then

amy get more money

Amy has more money than her brother after all transactions.

An equation is a statement that the depicts the values of two mathematical expressions as equal using an (=) sign. Example -

2x = 5

An expression is written using individual terms (either constant or variable) separated by mathematical operations. Example -

3x + 5y + 3

We have Amy who has $1275 less than her brother ben. Ben spends $550 and Amy gets $750.

Assume that the money with Ben and Amy after transactions is $x and $y respectively. Let Ben has a initial amount of $m and Amy has of $n.

n = m - 1275

After transactions -

x = m - 550

y = m - 1275 + 750 = m - 525

Now -

m - 525 > m - 550  for every value of [m].

So, now Amy has more money.

Therefore, Amy has more money than her brother after all transactions.

Answer:

The cow's tail will grow 25 inches more intotal

The cows tail will be 28 inches long.

Step-by-step explanation:

12 months equals to one year (leap year not included) cows tail

grows 5 inches every 6 months. So, 5 x 5 = 25 + the 3 inches from its previous tail will give us total for all. so the answer is 28 in all or 25 for how much it has grown.

That's a long tail ;-;

Answer:

1/3

Step-by-step explanation:

1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!

2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.

Answer:

1st one: x = -2

2nd one: x = -4

Step-by-step explanation:

1. Step 1: Rewrite into an equation.

Step 2: Simplify both sides of the equation.

Step 3: Subtract 109 from both sides.

Step 4: Divide both sides by -4.

Therefore, x = -2 for the first one.

2. Step 1: Rewrite into an equation.

Step 2: Simplify both sides of the equation.

Step 3: Subtract 36 from both sides.

Step 4: Divide both sides by -36.

Therefore, x = -4 for the second one!
