Answer 1

Answer:

The mass of 10mL of this liquid would be 25g.

Step-by-step explanation:

The formula for mass in relation to density and volume is:

mass=Density*volume

Knowing this, we could plug in the given volumes and solve:

m=Dv

m=(2.5g/mL)*(10mL)

m=25g

I hope this helps!

11.) The sum of four consecutive even
integers is 68. Find the four consecutive
even integers. What is the 3rd integer
in the sequence?

Answers

Answer:

Four consecutive even integers are 14, 16, 18 and 20
Third number in the sequence is 18

Step-by-step explanation:

Let N be the first even integer

Each consecutive integer is 2 away from the previous integer

Next consecutive integer = N + 2, next one = N+4 and the last one = N +6

Add these expressions together, set them equal to 68 to solve for N

==> N + (N +2) + (N +4) + (N + 6) = 68

==> N + N +2 + N +4 + N + 6 = 68

==> 4N + 12 = 68

==> 4N = 68-12

==> 4N = 56

N = 56/4 = 14

So the integers are 14, 16, 18 and 20

Third integer in the sequence is 18

The required solution after three successive iterations is near x = 7/8. Option c is correct.

What is the equation?

The equation is the values of two expressions that are equal. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here, we have,

Equation is -2x + 6 = -(2/3)^x + 5. Approximate the solution to the equation above using three iterations of successive approximation.

given that,

-2x + 6 = -(2/3)^x + 5

Arranging the equation

(2/3)^x - 2x + 1 = 0

Since the solution of the equation is when f(x) = 0 at near to x = 0.8

f(x) = (2/3)^x - 2x + 1

First iteration at x =0.8

f(0.8) = 0.123

It will go up more to get exact zero, so

Second iteration at x = 0.9

f(0.9) = -0.106

It seems that zero is near 0.9 so will go down

The third iteration at x = 0.87

f(0.87) = -0.037

Here , solution is much near to x = 0.87 or x =7/8.

Thus, the required solution after three successive iterations is near x = 7/8.

Answers

The shortest distance between n and p in units = (1 − a )2+ ( b+ 2)2.

The correct option is B.

Distance between two points:

The length of line segment connecting any two points is known as their distance from one another. The length of a line segment connecting the two given coordinates can be used to calculate the distance between the points in coordinate geometry.

What is coordinate geometry used for?

The study of geometry utilizing coordinate points is referred to as coordinate geometry (or analytic geometry). The distance between two points can be calculated using coordinate geometry, as can the areas of triangles in the Cartesian plane, the midpoints of lines, and more.

According to the given information:

The expression that represents this same shortest distance between P and N in units is found to use the distance between two points to be:

[tex]d=\sqrt{(1-a)^2+(b+2)^2}[/tex]

The distance between two points, (x1,y1) and (x2,y2), is represented by:

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

the distance between the points N(a, -2) and P(1,b) is:

[tex]\begin{aligned}&d=\sqrt{(1-a)^2+(b-(-2))^2} \\&d=\sqrt{(1-a)^2+(b+2)^2}\end{aligned}[/tex]

The shortest distance between n and p in units = (1 − a )2+ ( b+ 2)2.

Solve for x: 3x − 2 > 5x + 10. (5 points)

Question 9 options:

1)

x > 6

2)

x −6

Answers

Answer:

x < -6

Step-by-step explanation:

3x - 2 > 5x + 10

first step is to isolate x

3x -2 >5x +10

3x > 5x + 10 + 2

3x -5x > 10 + 2

now that we have 3x and -5x we can combine them

-2x > 10 + 2

now add 10 +2 =12

-2x > 12 (now divide by -2)

x < -6 (when we divide we flip the inequality sign)

the number of units expected to be sold is uniformly distributed between 300 and 500. if r is a random number between 0 and 1, then the proper expression for sales is

Answers

300 + (200)r is the proper expression for sales if the number of units expected to be sold is uniformly distributed between 300 and 500. If r is a random number between 0 and 1.

What is a random number?

a random number is a number chosen by chance -- i.e., randomly, from a set of numbers. All the numbers in a specified distribution have equal probability of being chosen randomly.

Given that r is a random number between 0 and 1. it is uniformly distributed between 300 and 500 will be done by using the formula of 300+200r.

If r = 0, 300+200r will result in the output as 300

If r = 0.5, 300+200r will result in the output as 400

If r= 1, 300+200r will result in the output as 500

Hence ,the proper expression for sales is 300+200r
