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:

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

Step-by-step explanation:

Graph both lines and find the intersection.

Answer:

If you multiply 38*(-36) you would get -1368. And to convert that into a fraction it could be -1368/1, -13680/10, etc.

Step-by-step explanation:

Answer:

-1368/1

Step-by-step explanation:

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!

Answer:

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

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:

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 ;-;

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:

[tex]x<3[/tex]

Step-by-step explanation:

[tex]3\left(x-9\right)<-18[/tex]

Divide both sides by 3

[tex]\frac{3\left(x-9\right)}{3}<\frac{-18}{3}[/tex]

[tex]x-9<-6[/tex]

Add -9 to both sides:

[tex]x-9+9<-6+9[/tex]

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:

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
