Express this number in scientific notation.
31 billion

Answers

Answer 1
31 x 10 raised to power of 10

Hope this helps
Answer 2

Answer:

3.1 * 10^10

Step-by-step explanation:

we know 1 billion is 1,000,000,000

In scientific notation

1,000,000,000=1 * 10^9

To find the value of 31 Billion

Multiply the value of one billion for 31

so

31 * 1 * 10^9  = 31 * 10^9

= 3.1 *  10^10

5(4x-10)+10x = 4(2x-3)+ 2(x-4)? is equal to - 7/4 or - 1/4 or 3/20 or 3/2 ?

Answers

Answer:

x is equal to 3/2

Step-by-step explanation:

Let's solve it!

5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)

expand:

20x - 50 + 10x = 8x - 12 + 2x - 8

group like terms:

30x - 50 = 10x - 20

factor out common multiples:

3x - 5 = x - 2

group terms again:

3x - x = -2 + 5

2x = 3

and divide both sides by two:

x = 3/2

y=2x-20
y= -5x+b

Answers

Answer:

b = 43

Step-by-step explanation:

So let's plug things in first:

y= 2x - 20 and y= -5x +b which can become →

2x - 20 = -5x + b (now you said that x=9 so let's plug that in)

2(9) -20 = -5(9) + b (now try solving that)

18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)

43 = b ( and there's your answer )

The Perimeter of the scalene triangle is 54.6cm

Which equation can be
used to find the value of b if side a measures 8.7 cm?

a 8.7+b=54.6
b 17.4+ b = 54.6
c 26.1 + b = 54.6
d 34.8+b =54.6

Answers

Answer: B. 17.4+b=54.6

Step-by-step explanation:

Edgen 2023

The equation can be used to find the value of b is 54.6 = 34.8 + b.

We have,

The border of the triangle is54.6 cm

and side a = 8.7 cm,

So, Perimeter = sum of the lengths of the three sides

54.6 = a + 3a + b

54.6 = 4a + b

We know a= 8.7 then

54.6 = 4(8.7) + b

54.6 = 34.8 + b

Therefore, the needed equation is54.6 = 34.8b.

What is the equation of a line with Point A(0, 4) and Point B(2,-6) ?

Answers

9514 1404 393

Answer:

  y = -5x +4

Step-by-step explanation:

The slope can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (-6 -4)/(2 -0) = -10/2 = -5

The point (0, 4) tells you the y-intercept is b = 4. So, the equation in slope-intercept form is ...

  y = mx +b . . . . . where m is slope and b is y-intercept

  y = -5x +4

Which graph represents f(x) and the inverse f^-1(x)

Answers

Answer:

D

Step-by-step explanation:

The inverse or f⁻¹(x) of a function f(x) is the graph being reflected over the line y = x.

For A, f(x) is reflected over the x-axis.

For B, f(x) is rotated about a point.

For C, f(x) reflected over the y-axis.

And for D, f(x) is reflected over the line y = x.

So, the graph that represents f(x) and its inverse f⁻¹(x) is choice D.

Answer: D. 150

Step-by-step explanation:

Given equation: [tex]3(3x-10)=5(x+10)[/tex] , it shows the relationship between the perimeter of an equilateral triangle and the perimeter of an equilateral triangle.

Consider [tex]3(3x-10)=5(x+10)[/tex]

[tex]\Rightarrow\ 9x-30=5x+50\\\\\Rightarrow\ 9x-5x= 50+30\\\\\Rightarrow\ 4x= 80\\\\\Rightarrow\ x=\dfrac{80}{4}\\\\\Rightarrow\ x= 20[/tex]

Now, perimeter of pentagon  = 5(x+10) = 5 (20+10)

= 5(30) = 150

Hence, option D is correct.

Sasha walks at a constant rate. She meets her friend Hannah 0.6 kilometer along the way, and thet continue walking at the same constant rate. When thay get to school, Sasha has walked for 0.6 hour and Hannah has walked 0.45 hour. What is the rate in kilograms per hour at which they walked to school

Answers

Answer:

4 km/hr

Step-by-step explanation:

Sasha walks at a constant rate. She meets her friend Hannah 0.6 kilometer along the way, and they continue walking at the same constant rate. When thay get to school, Sasha has walked for 0.6 hour and Hannah has walked 0.45 hour.

Let

the rate of the speed at which they walked to school be represented by r

Distance to school for Sasha = Distance to school for Hannah

Distance = Speed (rate × time)

Hence:

0.6r = 0.45r + 0.6

Collect like terms

0.6r - 0.45r = 0.6

0.15r = 0.6

r = 0.6/0.15

r = 4 km/hr

The rate in Kilometer per hour at which they walked to school is 4km/hr

Determine the length of CB.

Answers

Answer:

Step-by-step explanation:

The diagonal of a square is √2 times the edge length, so the length AB will be (1/2)√2(2 cm) = √2 cm.

Then the length CB is given by the Pythagorean theorem as ...

  CB = √(AC^2 +AB^2) = √((2 cm)^2 + (√2 cm)^2) = √(4 +2) cm

There are 13 girls on Janelle's soccer team. Uniforms cost $32 each. Which equation uses estimation correctly to show about how much money the team spent?

Answers

Answer:

$416

Step-by-step explanation:

From the above question,

Total number did people in a team = 13 girls

Uniform of each member of team = $32

The amount of money the team spent can be calculated as:

$32 × x

Where x = Number of people on the team = 13

The amount spent = $32 × 13

= $416

The amount the team spent is $416
