Anthropologists and archaeologists study the cultures, languages, archaeological remains, and physical characteristics of people across the world and through time. Typically, they conduct research to answer questions and test hypotheses about human behavior and culture.

Answer:

1.37×10^9 is in scientific notation

Answer:

the slope is 3/2

Step-by-step explanation:

(x1,y1)= (2,7)

(x2,y2)= (4,10)

slope=

[tex] \frac{y2 - y1}{x2 - x1} = \frac{10 - 7}{4 - 2} = \frac{3}{2} [/tex]

Answer:

  4.09 seconds

Step-by-step explanation:

The ball is in the air until h(t) = 0. Solving that equation for t, we have ...

  0 = -16t^2 +64t +6

  t^2 -4t = 3/8 . . . . . . rearrange, divide by 16

  t^2 -4t +4 = 4 3/8 . . . add 4 to complete the square

  (t -2)^2 = 4.375 . . . . write as a square

  t = 2 +√4.375 . . . . . positive square root, add 2

  t ≈ 4.09165

The ball was in the air about 4.09 seconds.

Answer:

g=(q+x)/(h)

Step-by-step explanation:

you would 1st add x to the q

g/h=q+x

then you would divide the h from both sides

g=(q+x)/(h)

Answer:

x - 5y = - 10

Step-by-step explanation:

y = mx + b (b is y-intercept)

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~~

x + 4y = 8 ⇔ y = [tex]-\frac{1}{4}[/tex] x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are (0, 2)

(5, 3)

m = [tex]\frac{3-2}{5-0}[/tex] = [tex]\frac{1}{5}[/tex]

y = [tex]\frac{1}{5}[/tex] x + 2 (slope-intercept form)

x - 5y = - 10 (standard form)

Answer:

No, there is no enough flour for each of his friends to get a cupcake

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ This recipe makes 2[tex]\frac{1}{2}[/tex] dozen cupcakes

∵ Each dozen contain 12 cupcakes

∴ The number of cupcakes can the recipe make = 2[tex]\frac{1}{2}[/tex]  × 12

∴ The number of cupcakes can the recipe make = 30 cupcakes

∵ The recipe calls for 3[tex]\frac{1}{3}[/tex] cups of flour

→ That means 3[tex]\frac{1}{3}[/tex] cups of flour can make 30 cupcakes

∴ 3[tex]\frac{1}{3}[/tex] cups of flour makes 30 cupcakes

∵ Anthony’s mother has only 1 cup of flour

→ By using the ratio method

→  flour  :  cupcake

→  3[tex]\frac{1}{3}[/tex]      :  30

→   1       :   x

→ By using cross multiplication

∵ 3[tex]\frac{1}{3}[/tex] × x = 1 × 30

∴ 3[tex]\frac{1}{3}[/tex] x = 30

→ Divide both sides by 3[tex]\frac{1}{3}[/tex]

∴ x = 9

∵ x represents the number of cupcakes  

∴ Anthony’s mother can make 9 cupcakes with 1 cup of flour

∵ Anthony has 12 friends at his daycare

∵ The number of the cupcakes = 9

∴ The number of cupcakes is not enough for each of his friends to

   get a cupcake

Answer:

7.5

Step-by-step explanation:

thank you!!!!

Answer:

Step-by-step explanation:

Step one:

given data

the initial amount of chemical = 1.25 ounces

Extra amount of chemical =2.5 ounces

Total amount of chemical =1.25+2.5=3.75 ounces

Step two:

we are told that the scientist used 0.75 ounces of chemical

Hence the remaining chemical is

remaining= 3.75-0.75

remaining= 3 ounces

The remainder is 3 ounces

Answer:

2(x-3x) + 3

value of X and M is x and -3x respectively

Step-by-step explanation:

you can factor out the 2 from the 2x -6x and gets the 2(x-3x) while n is the constant that remains the value of 3

Answer:

m = - 3, n = - 6

Step-by-step explanation:

Expand and compare coefficients of like terms, that is

(x + m)² + n

= x² + 2mx + m² + n

Compare to x² - 6x + 3

comparing coefficients of x- term

2m = - 6 ( divide both sides by 2 )

m = - 3

Comparing constant terms

m² + n = 3 , that is

(- 3)² + n = 3

9 + n = 3 ( subtract 9 from both sides )

n = - 6

Answer:

Step-by-step explanation:

1. Make a proportion.

Set the numbers equal to each other.

I chose the numbers 9, 12, 15, and of course x.

Make the fractions in a way that the x is in the numerator if you want to make your life easier.

15/9 = x/12

2. Simplify

Cross multiply the numbers.

This will give you the equation of

9*x and 15*12

3. Make an equation

Simplify the numbers by mulitplying them

9x = 180

4. Divide both sides by 9

9x = 180
