Find the area of the shape below. All measurements are in miles.

Kazeer [188]

Answer:

C

Explanation:

On the scatter plot, there is a dot where the lines for 6 and 3 meet. when looking for the ordered pair you would go along first then up (> then ^) so it would be (6,3). Another example, for the third dot on the plot, if you go along first you get 12 then when you go up you get 9 so the ordered pair for that would be (12,9). I really hope you understand what i mean and this helps as i struggled with explaining haha!

A pond has 150 fish and the population decreases by 8% each day. How many days before there are 30 fish

nlexa [21]

Answer:

19 days

Step-by-step explanation:

Given

$a = 150$ --- initial

$r = 8\%$ -- rate

Required

Days when the fish gets to 30

The function is exponential and as such it follows;

$y = ab^x$

Where x represents the number of days and y the number of fishes

Because the fishes decreases;

$b = 1 - r$

So, we have:

$b = 1 - 8\%$

Express as decimal

$b = 1 - 0.08$

$b = 0.92$

In $y = ab^x$

$a =150$

$y = 30$

$b = 0.92$

So, we have:

$30 = 150 * 0.92^x$

Divide both sides by 150

$0.2 = 0.92^x$

Take log of both sides

$log(0.2) = log(0.92^x)$

Apply law of logarithm

$log(0.2) = x\ log(0.92)$

Make x the subject

$x = \frac{log(0.2)}{log(0.92)}$

$x = \frac{-0.6990}{-0.0362}$

$x = 19.309$

$x \approx 19$

<em>Hence, it takes approximately 19 days</em>

Hey ok i need help on this question ive been stuck on it for a couple minutes haha

Len [333]

Answer:

The side s has a length of 4 and side q has a length of 4 $\sqrt{3}$ ⇒ F

Step-by-step explanation:

In the 30°-60°-90° triangle, there is a ratio between its sides

side opp (30°) : side opp (60°) : hypotenuse

1 : $\sqrt{3}$ : 2

In the given triangle

∵ The side opposite to 30° is s

∵ The side opposite to 60° is q

∵ The hypotenuse is 8

→ Use the ratio above to find the lengths of s and q

side opp (30°) : side opp (60°) : hypotenuse

1 : $\sqrt{3}$ : 2

s : q : 8

→ By using cross multiplication

∵ s × 2 = 1 × 8

∴ 2s = 8

→ Divide both sides by 2

∴ s = 4

∴ The length of s is 4

∵ q × 2 = $\sqrt{3}$ × 8

∴ 2q = 8 $\sqrt{3}$

→ Divide both sides by 2

∴ q = 4 $\sqrt{3}$

∴ The length of q is 4 $\sqrt{3}$

Answer quick please,

lbvjy [14]

Answer:

132 minutes

Step-by-step explanation:

1 Km = (60)(8)+15=495 seconds

4 mornings = (495)(4) =1980 seconds

4 weeks = (1980)(4) = 7920 sec.

7920/60 = 132 minutes

I need to know the step by step and answer pls and thanks

avanturin [10]

Answer:

(a) $p^{10}$

In this question, you can simply just multiply the exponent of 2 and the exponent of 5, in order to get a power of 10.

(b) $2x^{4}y^{2}$ For this question, we need to organize the numbers as a fraction

$\frac{12x^{7}y^{3} }{6x^{3 } y^{} }$

We need to subtract the exponents from each variable. In $y^{3}$ and y, we need to subtract 3-1 to get $y^{2}$ . In $x^{7}$ and $x^{3}$ , we need to subtract 7-3 to get $x^{4}$ . Now, we can divide 12 and 6 normally to get 2. So, the answer would be $2x^{4}y^{2}$ .
