Putting recipe makes 4 1/2 cups of pudding. How many 1/3 cup servings does this equal?

mel-nik [20]

Answer:

C

Step-by-step explanation:

First, write 4 ½ in improper form. 2 × 4 + 1 = 9. So the fraction is 9/2.

Now divide:

9/2 ÷ 1/3

To divide by a fraction, multiply by the reciprocal:

9/2 × 3/1

27/2

13 1/2

Answer C.

Question : A square game board is divided into smaller squares, each with sides one-ninth the length of the sides of the board.

bagirrra123 [75]

Answer:

Therefore the game board is divided into 81 smaller squares.

Step-by-step explanation:

Given that, there is a square game.

Consider x be length of one side the square.

The volume of the square is = side ×side

=x² square units

Since the length of side of smaller square is one-ninth of the game board.

Then one side length of the smaller square is $\frac19x$ units.

The area of a smaller square is $=(\frac19x)\times (\frac19x)$

$=\frac{1}{81}x^2$

Let a number of square is formed from the game board.

a ×The area of one smaller square= The area of game board.

According to the problem,

$a\times (\frac{1}{81}x^2)=x^2$

$\Rightarrow a =\frac{x^2\times 81}{x^2}$

$\Rightarrow a= 81$

Therefore the game board is divided into 81 smaller squares.

Find the equation of a line given that: slope =5, y-intercept is (0,4). Standard form or slope intercept form?

Pie

So the slope is 5 and you know the points, (0,4)
y-4=5(x-0)
y-4 = 5x
y = 5x + 4 is the slope intercept form
standard form is: -5x + y = 4 OR y - 5x = 4

The population of a heard of cattle numbered was 5000 to begin with and was 10,000 after 10 years. If the population was growing

Lapatulllka [165]

Answer:

$r=0.0718$ . The closest value from your given choices is C)r=0.69

Step-by-step explanation:

To solve this we are using the standard exponential growth equation:

$f(t)=A(1+r)^t$

where

$f(t)$ is the final population after $t$ years

$A$ is the initial population

$r$ is the growth rate in decimal form

$t$ is the time in years

We know from our problem that the initial population is 5000, the final population is 10000, and the time is 10 years, so $A=5000$ , $f(t)=10000$ , and $t=10$ .

Let's replace the values and solve for $r$ :

$f(t)=A(1+r)^t$

$10000=5000(1+r)^{10}$

Divide both sides by 5000

$\frac{10000}{5000} =(1+r)^{10}$

$2=(1+r)^{10}$

Take root of 10 to both sides

$\sqrt[10]{2} =\sqrt[10]{(1+r)^{10}}$

$\sqrt[10]{2} =1+r$

Subtract 1 from both sides

$\sqrt[10]{2}-1=r$

$r=\sqrt[10]{2}-1$

$r=1.0718-1$

$r=0.0718$

We can conclude that the growth rate of our exponential equation is $r=0.0718$ . The closest value from your given choices is C)r=0.69
