One city has a population of about 2,840,000 people. Another city has
about 3,120,000 people. About how many people live in both cities?

Answers

Answer 1

Answer:

5,960,000

Step-by-step explanation:

Population in one city= 2,840,000

Population in another city= 3,120,000

Population living in both cities= 2,840,000 + 3,120,000 = 5,960,000

Answers

Answer:

variable

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Create three different expressions that are each equal to 20. Each expression should include only these three numbers: 4, -2, and 10.​

Answers

Answer:

Step-by-step explanation:

you could do;

10 x -2 = 20

-2 x (-2) x 10 divided by (-2) + 10 + 10 + 10 +10 =20

4 + 4 - 10 x -2 - 4 - 4 = 20

A rule that airline pilots use to estimate outside temperature in degrees Fahrenheit at an altitude of h thousand feet is to double h, subtract 15, and multiply the result by -1. State a rule for the altitude in feet based upon the outside temperature. At what altitude is outside temperature about -51°F?​

Answers

Answer:

The altitude is 33 thousand feet at the given temperature

Step-by-step explanation:

We firstly would need to write out the rule.

We can do this by by doubling h, subtracting 15 and multiply the result by -1

Kindly note that h is in thousands of feet

That would be ;

T = (2 * h - 15) * -1

T = -1(2h - 15)

T = -2h + 15

T = 15 - 2h

So for the altitude in feet at a temperature of - 51 degrees Fahrenheit

We simply substitute the value of -51 for the temperature

So we have;

-51 = 15 - 2h

2h = 15 + 51

2h = 66

h = 66/2

h = 33 thousand feet

Find the distance between the points (-3,7)
and
(6, 7).

Answers

Answer:

9

Step-by-step explanation:

use the distance formula:

[tex]\sqrt{(x2 -x1)^{2} + (y2-y1)^{2} }[/tex]

so, with your two points, x2=6, x1=-3, y2=7, and y1=7

so then just plug in the values

[tex]\sqrt{(6--3)^{2} + (7-7)^{2} }[/tex]

because you have 6 minus a negative number, it turns into 6+3, like shown

[tex]\sqrt{(6+3)^{2} + (7-7)^{2} }[/tex]

so then add and subtract the parenthesis

[tex]\sqrt{(9)^{2} + (0)^{2} }[/tex]

so then because 0 squared is just zero, you simply have the square root of 9 squared

[tex]\sqrt{9^{2} }[/tex]

so then square the 9

[tex]\sqrt{81}[/tex]

then take the square root of 81, and you get 9!

[note that when you have the square root of a squared number, it is just the number, so the square root of 9 squared is just 9, but if it helps, you can work it out like I did to show you :)]

What is the distance between two points of a line?

The distance between two points of a line is given as:

Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]

Where (a, b) and (c, d) are the two points.

We have,

(-3, 7) = (a, b)

(6, 7) = (c , d)

Now,

Distance between these two points.

= [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]

= √(6 + 3)² + (7 - 7)²

= √9²

= 9

Thus,

The distance between the points is 9.

I just took a science test and got a 80% on the test. CBA's are 50% of our grade and I had a 98% in science class. How much will my grade drop?, what will my new grade be?​

Answers

Answer:

89%

Step-by-step explanation:

Answer:

Grade drops 9 percentage points.

New overall grade is 89%

Step-by-step explanation:

The test with a score of 80% accounts for 50% of the grade.

The current average of 98% accounts for the other 50% of the grade.

50% of 80% + 50% of 98% =

= 40% + 49%

= 89%

The new overall grade is 89%.

Since the previous overall grade, before the test, was 98%,

and 98% - 89% = 9%, then

the new grade is 9 percentage points lower than the previous overall grade.

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

The graph of y = f(x) is shown. Choose all the true statements.

−2 is a member of the range of f.
f(0) > 0
f(2) > 2

Answers

Answer:

−2 is a member of the domain of f.

f(0) > 0

Step-by-step explanation:

Statement 1 is TRUE. Domain value includes set of values of x of the function. -2 is plotted on the x-axis on the graph. Therefore, it is a member of domain of f.

Statement 2 is incorrect. Range includes all possible y-values of the function. On the graph, no y-value plotted is -2. Therefore, -2 is NOT a member of the range of f.

Statement 3 is TRUE.

f(0) is approximately 2.2 on the graph. i.e. at x = 0, y ≈ 2.2.

Therefore, f(0) > 0.

Statement 4 is INCORRECT.

f(2) = 1, that is at x = 2, y = 1 as seen in the graph. Therefore, f(2) is not greater than 2.

The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so

I don't understand why the answer is y=3x+1.
I got y =3x-6
please help me.​

Answers

Answer: Answer is y= 3x+1

Step-by-step explanation:

Use point slope form y-y°=m(x-x°)

Find m, the slope: subtract the y values of the points, and divide that with the number you get when you subtract the x values of the points.

You should get m=3

Take either of the points, I’ll choose (0,1) because they are easy to use. Substitute 0 for x° and 1 for y°.

y-(1)=3(x-(0)) Substitute (0,1)

y-1=3x Simplify

y=3x+1 Add 1 to both sides and you’re done
