Answer:

Steve is 18 and and his mother is 47.

Step-by-step explanation:

if you add those numbers you'll get 65

[tex]\log_4 21 = \dfrac{1}{2}\cdot \log_2 21 = \dfrac{1}{2}\cdot \left(\log_23+\log_2 7\right) \approx \dfrac{1}{2}\cdot\left(1.584+2.807\right) \approx 2.196[/tex]

Answer:

The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.

Let width = x

Let length = x + 4

Perimeter = 48

We can set an inequality for perimeter using the variables.

2x + 2(x + 4) ≥ 48

Solve for x.

2x + 2x + 8 ≥ 48

4x + 8 ≥ 48

4x ≥ 40

x ≥ 10

Substitute this value of x into the variable to get your width and length.

width = 10 cm

length = 14 cm

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attached file.

In the given equation, when the point t=0

So,

[tex]\to r(0) = (3 \cos 0)i + (0^4 - 6 \sin 0)j + (2e^{3\times 0})k)[/tex]

           [tex]= (3 \times 1)i + (0 - 0)j + (2e^{0})k)\\\\ = 3i + 0j + (2 \times 1)k)\\\\ = 3i + 0j + 2k \\[/tex]

The value of the coordinates are [tex]3, 0, 2[/tex] . so, the equation of the line is:

[tex]\to \frac{(x-3)}{3 \cos \ t} = \frac{(y-0)}{(t^{4}-6 \sin \ t)} = \frac{(z-2)}{2e^{3t}}=k[/tex]

Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.

Step-by-step explanation:

Volume of cylinder= volume of blood it can hold = [tex]\pir^2h[/tex]

Given :

Height of cylinder (h) = 9.5 cm

Diameter of cylinder (d) = 0.85 cm

Thus radius of cylinder (r) = [tex]\frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm[/tex]

Putting the values we get:

Volume of cylinder= volume of blood it can hold = [tex]3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3[/tex] [tex]      (1cm=0.1dm)

Thus 0.539 cubic decimeters of blood can be hold by the cylinder.

Answer:

The percentage is a statistic, because it is a mesure of the sample.

Step-by-step explanation:

The difference of statistic and parameter is given by:

Statistic is a measure of the sample.

Parameter is a measure of the population.

In this question, we have that:

The measurements of 100 products from the assembly line show that 99% are correct.

This is the percentage from a sample of 100 products, not from an entire population, so the percentage is a statistic.

Step-by-step explanation:

Answer:

612 students and 325 adults.

Step-by-step explanation:

To determine the number of adults and students who attended the event, knowing that in total there were 937 people who spent a total of $ 1,109 and that each student ticket is worth $ 0.75 while each adult ticket is worth $ 2, the following logical reasoning must be performed:

2 - 0.75 = 1.25

Therefore, the minimum that each ticket will be worth is $ 0.75, while there will be a surplus of money that will be divisible by 1.25, which is the amount of more that each adult paid on their ticket.

Therefore, since 0.75 x 937 equals 702.75, the total price surplus is 406.25 (1,109 - 702.75). Now, this number divided by 1.25 gives a total of 325, with which 325 adults attended the event. In turn, given that the total number of attendees was 937, the total number of students who attended the event is 612 (937 - 325).

Answer:

[tex]\huge\boxed{1000 \ \text{cm}^3}[/tex]

Step-by-step explanation:

There are two ways we can solve this equation.

The formula provided states that the volume of a cube based on the area of one of it's faces will be [tex]a^{\frac{3}{2}}[/tex], a the area of one face. Since we know the area of one face, we can substitute that inside the equation.

[tex]100^{\frac{3}{2}}[/tex]

It's important to note that when we have a number to a fraction power, it's the same as taking the denominator root of the base to the numerator power.

So - [tex]100^{\frac{3}{2}}[/tex] becomes [tex]\sqrt{100^3}[/tex]

Therefore, the volume of this cube will be [tex]1000 \ \text{cm}^3[/tex]

We can additionally use prior knowledge to find the volume of this cube.

We know that the area of a square will be [tex]s^2[/tex], where s is the length of a side. We also know the formula to find the volume of a cube from it's side length is [tex]s^3[/tex].

Since we know that one face is 100, we can make an equation - [tex]s^2=100[/tex]

Now that we know the value of s, we can plug it into the volume formula, [tex]s^3[/tex].

So the volume is [tex]1000 \ \text{cm}^3[/tex].

Answer:

The answer is given by option c.

Step-by-step explanation:

Linear function:

The graphic of a linear function is a straight line.

In this question:

We have a straight line for x between -2 and 0, so in this interval the function is linear.

For x between 0 and 2, the function is a curved line, so not linear in this interval.

We also have a straight line for x between 2 and 4, so in this interval the function is linear.

So it is linear in the following intervals: -2 < x < 0, 2 < x < 4, so the answer is given by option c.

Answer: 125 miles

Step-by-step explanation:

We know that 25 miles is 20% of the trip.

20% is 1/5 of 100, so that means we will multiply the number of miles driven by the denominator of the fraction.

25 × 5 = 125 miles

The answer to the question is 125 miles.

Answer:

15²+40²=42.72

Step-by-step explanation:

In this particular problem, you can use pythagorean theorem. The pythagorean theorem consists of the formula a²+b²=c². This theorem is mostly used when solving for the hypotenuse in a right triangle.

In this problem,

a=15

b=40

c=? (this is the hypotenuse)

then, plug the numbers into the formula

a²+b²=c²

15²+40²=?

15²=225

40²=1600

1600+225=1825

or you could just punch the numbers in a calculator

then take the square root of 1825 to find your answer

√1825=42.72

Hope this helps! :)
