The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = [tex]5*10^5[/tex]

Number of viruses = [tex]2*10^9[/tex]

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

[tex]2*10^9=(5*10^5)x[/tex]

Dividing both sides by [tex]5*10^5[/tex]

[tex]\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000[/tex]

The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Let x be the adult weight of a puppy A

25% of x = 8 pounds

[tex]\frac{25}{100}*x=8\\\\ x=\frac{8*100}{25}\\\\ =8*4=32pounds\\[/tex]

Final answer:

To calculate the adult weight of Puppy A, divide the current weight of 8 pounds by 0.25 since 8 pounds is 25% of the adult weight. The adult weight of Puppy A is 32 pounds.

Explanation:

The student is asking how to find the adult weight of Puppy A, given that its current weight is 25% of its adult weight. To solve this, we need to use the concept of percentages. If Puppy A currently weighs 8 pounds and this represents 25% of the adult weight, we can set up a proportion:

25% (current weight) / 100% (adult weight) = 8 pounds / adult weight

To find the adult weight, we divide 8 pounds by 25% (0.25 in decimal form):

Adult weight = 8 pounds / 0.25

Adult weight = 32 pounds

Therefore, the adult weight of Puppy A is expected to be 32 pounds.

Step-by-step explanation:

We know that the length of the garden is 4 - (-3) = 7 feet, the answer is (Negative 3, 5) and (4, 5).

A vertex is a point in geometry where two or more curves, lines, or edges intersect.

As a result of this definition, vertices are the points where two lines intersect to form an angle, as well as the corners of polygons and polyhedra.

Let's assume that the other two vertices are at points (a, b) and (c, d). The area of the garden can be calculated as follows:

Area = Length × Width

35 = 7 × (b - (-1)) [since the width is the distance between the y-coordinates of the vertices]

Simplifying the above equation, we get:

b - (-1) = 5

b = 4

So, one of the vertices should be at (a, 4) and the other at (c, 4). Since the garden is symmetrical about the x-axis, the y-coordinate of the missing vertices is 1 more than the y-coordinate of the given vertices. Hence, the other two vertices should be at (−3, 5) and (4, 5).

Therefore, the answer is (Negative 3, 5) and (4, 5).

The value of y at x = 4 is 48.

Drawing the curve that represents a function on a coordinate plane is known as graphing a function. Every point on the curve will satisfy the function equation if the curve (or graph) reflects the function.

The given function is,

y = 3x²

And x = 4

To find the value of y,

Put x = 4 in the given fucntion we get,

Answer: 30+x+y

Step-by-step explanation:

Given : Number of CDs sold by friend on first day = 14

Number of CDs sold by friend on next day = x

Total CDs sold by friend  = 14 +x

Number of CDs sold by you on first day = 16

Number of CDs sold by you on next day = y

Total CDs sold by you  = 16+y

The expression that shows the total number of CDs sold both days =

Total CDs sold by friend  + Total CDs sold by you

=  14 +x+ 16+y

= 14 +(x+ 16)+y

= 14 +(16+x)+y   [By Commutative Property of Addition.]

= 14+16+x+y

= 30+x+y

Hence, the expression that shows the total number of CDs sold both days :

Answer:

1 3/5

Step-by-step explanation:

When you subtract the y values you find that each increase in x decreases y by 4.

X is going from 4 to 82 which is 78 units.

78 x 4 = 312

Subtract 312 from the last y value:

209 - 312 = -103

The answer is -103

Answer:

When x = 82, y = -103

Step-by-step explanation:

So an arithmetic sequence is a sequence whose terms differ by a constant value. To find the value of the [tex]n^{th}[/tex] term we need to form an equation for the sequence.

First we need to find the difference between the values of the sequence. In this case the difference is -4:

217 - 221 = -4,  209 - 213 = -4

So the equation is:

[tex]n^{th}[/tex] term = -4n + c

Now we need to find the c, so we substitute the [tex]n^{th}[/tex] term and the term number and solve the equation:

221 = (-4 x 1) + c

221 = -4 + c

c = 225

So the final equation is:

[tex]n^{th}[/tex] term = -4n +225

Now all we need to do is substitute into the equation and find the answer:

[tex]n^{th}[/tex] term = (-4 x 82) + 225

[tex]n^{th}[/tex] term = -328 +225

[tex]n^{th}[/tex] term = -103

Step-by-step explanation:

In a right-angled triangle, the longest side/leg is called the hypotenuse.

The formula to solve for the hypotenuse is:

hyp^2= side^2+side^2

If the hypotenuse of the triangle is already given then we have to solve for a side.

The formula to solve for the side is:

side^2= hyp^2-side^2

This formula to solve for the side is the opposite of solving for the hypotenuse which is the longest side/leg of the right-angled triangle.

In this question we have to solve for the side.

There are two sides in this triangle. Let's name those sides side a and side b. Side a is already given.

hyp= 9

side a = 7

side^2 = hyp^2-side^2

side b = 9^2 - 7^2

side b = 81 - 49

side b = 32

side b = √32

side b= 5.65685424949. to 2 decimal places -> 5.66

Final answer:

To find the number of boats in the marina, we use the information given about the proportion of white, blue, and red boats. By setting up an equation and solving for the total, we find that there are 222 boats in the marina.

Explanation:

To find the number of boats in the marina, we need to start with the information given. The problem tells us that five-sixths of the boats in the marina are white, and then 25 of the remaining boats are blue. The rest of the boats are red, with a total of 12 red boats.

We can start by finding the fraction of boats that are red. Since five-sixths are white, the remaining fraction of boats that are not white is one-sixth. We know that 25 boats are blue, so if we subtract this from the one-sixth, we are left with the fraction that represents the red boats.

Let's set up an equation to solve for the total number of boats:

1/6 - 25 = 12

Simplifying the equation, we have:

1/6 = 12 + 25

1/6 = 37

Multiplying both sides of the equation by 6, we get:

1 = 37*6

1 = 222

Therefore, there are a total of 222 boats in the marina.

The graph that shows the dilation of the rectangle in the attached figure

Step-by-step explanation:

we know that

A dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem we have that the scale factor is equal to 2

Remember that

If a scale factor is greater than 1, then the dilation is a enlargement

To find out the dimensions of the dilated figure multiply the original dimensions by the scale factor

The original dimensions of rectangle are

[tex]b=2 units\\h=4\ units[/tex]

The dimensions of the dilated rectangle are

Answer: [tex]62.92 \frac{mi}{h}[/tex]

Step-by-step explanation:

If we are asked about how fast a car is going, this means we are asked about its velocity [tex]v[/tex], which is defined by the relation between the traveled distance [tex]d[/tex] and time [tex]t[/tex]:

[tex]v=\frac{d}{t}[/tex]

Where:

[tex]d=(330+\frac{1}{3}) mi=330.33 mi[/tex] is the traveled distance

[tex]t=(5+\frac{1}{4}) h=5.25 h[/tex] is the time

Solving the equation with the given information:

[tex]v=\frac{330.33 mi}{5.25 h}[/tex]

Finally:

[tex]V=62.92 \frac{mi}{h}[/tex] This is the car's velocity

Answer:

The speed of the car is 77.72 miles per hour

Step-by-step explanation:

To find out how fast is a car travelling when it traveled 330 and 1/3 miles in 4 and 1/4 hours following formula will be used

     Speed=  [tex]\frac{Distance}{Time}[/tex]

Total distance = 330 and 1/3

                        = 330+ 0.33

                        =  330.33 miles

Total time = 4 and 1/4

                 =  4 + 0.25

                 =  4.25 hrs

putting the values in equation we get speed of car

Speed= [tex]\frac{330.33}{4.25}[/tex]

Speed   = 77.72 miles per hour

So the speed of the car is 77.72 miles per hour
