How does your estimate help you place the decimal
point in the product?

Answer:

It takes him 1 minute and 25 seconds

Step-by-step explanation:

5 ÷ 4 = 1.25

The number of laps per minute is 1.25 laps.

Given that, time = 4 minutes and the number of laps = 5.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

Number of laps per minute = Total number of laps/Number of minutes

= 5/4

= 1.25 laps

Therefore, the number of laps per minute is 1.25 laps.

QUICK ANSWER: 8,700,000

i believe the question is asking the difference between the total amount of people between NY and Pittsburg.

9×10^6 = 9,000,000 (NYC)

3×10^5 = 300,000 (Pittsburg)

subtract them and it helps you get your answer

Answer:

15/13

Step-by-step explanation:

Convert to improper fractions: 5/2 divided by 13/6

Multiply the first term by reciprocal: 5/2 * 6/13 = 30/26

Simplify: 30/26 can become 15/13

[tex] = 2 \frac{1}{2} \div 2 \frac{1}{6} [/tex]

[tex] = \frac{5}{2} \div \frac{13}{6} [/tex]

[tex] = \frac{5}{2} \times \frac{6}{13} [/tex]

[tex] = \frac{30}{26} [/tex]

[tex] = \frac{30 \div 2}{26 \div 2} [/tex]

[tex] = \frac{15}{13} [/tex]

[tex]\color{hotpink} = 1 \frac{2}{13} [/tex]

[tex]\therefore\color{olive}2 \frac{1}{2} \div 2 \frac{1}{6} = \color{hotpink} \frac{15}{13}\color{olive} (or) \color{hotpink}1\frac{2}{3} [/tex]

Answer: C=-3t+30

Step-by-step explanation:

The equation of remaining chocolate C  in terms of t could be C =30 - 3t.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given that the Initial number of chocolates in box = 30

Also after 8 nights, number of remaining chocolates = 6

Then we have

In 8 nights, 24 chocolates were treated.

In 1 night, 3 chocolates were treated.

The equation of remaining chocolate C  in terms of t can be written by;

C =30 - 3t.

Answer:

x=20

Step-by-step explanation:

Since supplementary angles =180 degrees, we need to write the equation as follows:

5x-30+x+90=180

Then you need to add like terms:

6x+60=180

Then you need to subtract 60 from both sides (60 and 180)

6x=120

Then divide both sides by 6 to get

x=20

Answer:

The boxes are classified as underweight or not. X, the number of underweight boxes will be approximately ___normally___distributed

Step-by-step explanation:

For a normal distribution the sample size must be less than or equal to 30.

The central limit theorem states that if a variable X from a population has a mean u and a finite variance σ² then the sampling distribution of the sample mean x bar approaches  a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.

In the given question the sample size n= 10 and population size N= 3000.

Here n < 30 . But if the population is normal this theorem holds true for sample size n < 30.

The number of underweight boxes should be normally distributed.

It is the distribution where the sample size should be lower than or equal to 30

Since the size of the sample is n = 10 and the size of the population is N = 3000

So here n should be less than 30

Therefore, it is normally distribution.

Answer:

B. (3,-6) and (7,-6)

Step-by-step explanation:

because when the slope is zero the y's should be the saem, for it's a straight horizontal line.

Answer:

A = (1/2)*b*h

objective: find dA/dt

given: b = 26, db/dt = 2, b = (1/2)*h

since we are given db/dt lets get area in terms of b

since b = (1/2)h that means h = 2b

so A = (1/2)*b*(2b) = b^2

Take derivative wrt time, t

dA/dt = 2b*db/dt

Answer:

x=6,0

y=0,-18

Step-by-step explanation:

Answer:

x-intercept: (6,0)

y-intercept: (0,-18)

Step-by-step explanation:

To find the x-intercept, set y=0 and solve for x.

2y=+17=6x-19

0+17=6x-19

6x=36

x=6

(6,0)

To find the y-intercept, set x=0 and solve for y.

2+17=6x-19

2y+17=0-19

2y=-36

y=-18
