Which expression represents the total number of fish in the two pond?

A. 22x^2+20x+23
B. 2x^2+20x-23
C. 2x^2-20x+23
D. 22x^2-18x-15

Answer:

Very, very distant relatives. Mammals and dinosaurs branched off from a common ancestor hundreds of millions of years ago. They may both have horns, but triceratops and rhinos are very different. Usually you wouldn't refer to them as “related.”

Answer: 20% Percent Discount

Step-by-step explanation:

$800.00 - $640.00=$160.00 / $800.00= .2 or 20%

Answer:

g(0) = -2

Step-by-step explanation:

g(x) = -x - 2

To find g(0), replace x with 0 in the equation.

g(0) = -0 - 2 = -2

Answer:

  8.6 cm

Step-by-step explanation:

We notice the hypotenuse is given, and the desired length is of the side opposite the given angle.

The mnemonic SOH CAH TOA reminds you of the relevant relationship:

  Sin = Opposite/Hypotenuse

  sin(35°) = x/(15 cm) . . . . . . fill in the given information

We can multiply by 15 cm to find the value of x.

  x = (15 cm)sin(35°)

  x ≈ 8.6

_____

For those inclined to copy this answer to a different question, we suggest ...

  y = (15 cm)cos(35°) ≈ 12.3 cm

Answer: 8.603646545 or rounded to the nearest tenth 8.6

Step-by-step explanation:

you are going to have to use (sin). so,

(15)sin(35)

8.603646545 or 8.6

this is correct.

Answer and Step-by-step explanation:

A. Cruz is correct.

B. When we have a negative within a cube root, what we can do is move the negative sign from inside to outside the cube root.

[tex]\sqrt[3]{-64} = -\sqrt[3]{64}[/tex]

Now that we have a positive number within the cube root, we can solve the cube root itself.

So what is the cube root of 64?

The answer is 4, and since we have a negative sign outside of the cuberoot, we just put a negative sign, our answer is -4.

C. Aaron could've got it wrong because he did it a square root instead of a cuberoot of 64. Square root of 64 is 8, while cube root is 4.

Jacob could've gotten it wrong because he must've followed the fallacy that you cannot cube root a negative number.

Answer:

[tex]p \ge 18[/tex]

Step-by-step explanation:

The question has missing details. See comment for missing information

Given

[tex]People = 18[/tex] -- at least

Required

Represent as an inequality

In inequalities:

At least means [tex]\ge[/tex] i.e. greater than or equal to

From the question, the number of people is represented with p.

So, at least 18 people is represented as:

[tex]p \ge 18[/tex]

Answer:

dimes:$8  quarters:$15

Step-by-step explanation:

im still in 6th grade

Answer:

55 dimes and 70 quarters

Step-by-step explanation:

Using a simple strategy of guess and check we know that the quarters will always be 15 more than dimes.  From this we know it has to be around the 50s as 40s would bring us numbers too low and 60s too high.  55 happens to be answer for dimes as that brings in $5.50. 23-5.5=17.5 multiply that by 4 as each quarter is only valued at $0.25 you get the answer 70 which just so happens to meet the requirements of being 15 more than 55.

Slope = rise over run

Answer: (0,-7)

HOPE I HELPED

Step-by-step explanation:

Answer:

-7

Step-by-step explanation:

Since you are trying to solve for y, you set all the x values to 0.

(Y intercept occurs when x = 0, thats why you sub 0 for all x)

y= -4(0)^2[tex]y=-4(0)^{2} +5(0) -7[/tex]

this simplifies to

y=-7

PLS PUT ME BRIANIEST

Step-by-step explanation:

Answer:

between 2014 and 2015

Step-by-step explanation:

Answer:

the slope is 2/7 and the intercept is 4

Step-by-step explanation:

In order to find slope, you use the equation delta y over delta x which is the equation, y2-y1/x2-x1.

In this case you plug in each point and get the equation, 2-4/-7-0 or 4-2/0+7.

Simplify to get 2/7.

To find the intercept, you must see what's the y value when x is 0. In this case it's already given to you, so y intercept is 4.

plz mark me brainliest aha.

Answer:

The slope is 4x and the y intercept is 3

Hope this helps. :)

Answer:

a

Step-by-step explanation:

mark me brainiest

and look up slope calculator and use omni calculator

[tex] \begin{cases}5 \in y \\ 6 \in y \\ 7 \in y \end{cases}[/tex]

[tex]y + 4 < 10 \\ y < 10 - 4 \\ y < 6[/tex]

Therefore, the value of y is lesser than 6. That meane it can't be y = 6 or greater. Hence, 5 is the solution to the Inequality.

y = 5 is the solution to the Inequality.

But if you want to solve for Inequality only then it is y < 6

Answer:

5efg equals 120

Step-by-step explanation:

2 * 3 * 4 * 5 = 6 * 4 * 5 = 30 * 4 = 120.

Answer:

5

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

use proportions. line up the sides based on the congruent angles. the sides opposite the singles line angle. = the sides opposite the double angle sides.

40/30 = 24/x

40x = 720

divide both sides by 40

x = 18
