Step-by-step explanation:

there is 20 balls and 5 are black, right? And if you do 5/20 it eachs 1/4 or 0.25.

Answer:

n= -7

Step-by-step explanation:

subtract 3 from both sides,-6n=42,divide both sides by -6

thank me later lol

Answer:

79.5

Step-by-step explanation:

Answer:

66.4, 70.4, 223.2

Step-by-step explanation:

make the equation x + (x+4)+ 3x+24=360

then it's 5x+28=360

subtract 28 on both sides

5x=332

then divide by 5 on both sides

x=66.4

then, just plug in the numbers

Answer:

180 degrees is the answer

Step-by-step explanation:

The rule of an 180⁰ degree rotation is:

(x,y) -> (-x,-y)

So the x and y coordinates change from negative to positive or from positive to negative

9514 1404 393

Answer:

  180°

Step-by-step explanation:

When you look at the coordinates, you see that each one has been negated. That is, the image point is in the quadrant opposite the one the preimage point is in.

Every point and its image on a rotated figure makes an angle with the center of rotation that is equal to the angle of rotation. When the preimage and image points are in opposite (not adjacent) quadrants, that angle is 180°.

______

Additional comment

It can be helpful to learn to recognize certain transformations. A rotation of 90° will swap the coordinates and negate one of them. A rotation of 180° negates both coordinates without swapping them.

Answer:

-28

Step-by-step explanation:

-7 x 4 = -28 because 7 x 4 =28 then add negative so -28

Hope this helped ;) Have a good day :D

Answer: You have to save $128 more dollars.

Step-by-step explanation: The iPad costs $353 and you already have $225, so to find the answer you have you subtract what you already have from how much it costs. So 353 - 225 = 128. You need to save up $128 more dollars to get the iPad. (I think this is correct, I tried)

Answer:

:⊃

Step-by-step explanation:

Answer:

Yes, it is

Step-by-step explanation:

Yes, because all x terms have null or positive integer exponents:

g(x) = -x^3 + 2x^1 + 8^0.

Step-by-step explanation:

Answer:

The estimated number of bacteria after 20 hours is 40.

Step-by-step explanation:

This is a case where a geometrical progression is reported, which is a particular case of exponential growth and is defined by the following formula:

[tex]n(t) = n_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial number of bacteria, dimensionless.

[tex]r[/tex] - Increase growth of the experiment, expressed in percentage.

[tex]t[/tex] - Time, measured in hours.

[tex]n(t)[/tex] - Current number of bacteria, dimensionless.

If we know that [tex]n_{o} = 30[/tex], [tex]r = 1.4[/tex] and [tex]t = 20\,h[/tex], then the number of bacteria after 20 hours is:

[tex]n(t) = 30\cdot \left(1+\frac{1.4}{100} \right)^{20}[/tex]

[tex]n(t) \approx 39.616[/tex]

[tex]n(t) = 40[/tex]

The estimated number of bacteria after 20 hours is 40.

Substitute x = 3 - 2 cos(θ) and dx = 2 sin(θ) dθ (where "sin" = "sen"). So we have

∫ sin(θ) / (3 - 2 cos(θ)) dθ = 1/2 ∫ 1/x dx

= 1/2 ln|x| + C

= 1/2 ln(3 - 2 cos(θ)) + C

(We can remove the absolute value because -1 ≤ cos(θ) ≤ 1, so 1 ≤ 3 - 2 cos(θ) ≤ 5, and |x| = x when x ≥ 0.)

Answer:

1. isosceles and acute

2. Scalene and acute

3. Equilateral and equiangular

4. Right (and isosceles ?)

(not sure ab isosceles for the last one but everything else is fine)

Answer:

15.6 meters in a minute

Step-by-step explanation:

Here's why:

1 centimeter= 0.01 meter

So, if you have 26 cm, that equals 0.26 meters.

Now, we know that there are 60 seconds in a minute.

So, we have to do 0.26 times 60 which equals 15.6 meters.

I hope this helps you! :)

Answer:

5 inches

Step-by-step explanation:

formula for cube volume is l^3

so 5^3 is equal to

5 x 5 x 5

which is

25 x 5

equals

125

Hope this helps!

Answer:

5 inches

Step-by-step explanation:

V=a^3

5^3 is 125 so the answer is 5

Answer:

468,119 < 486,191

Step-by-step explanation:

compare the left numbers. Four is equal to four, so go right. 6 is less than 8, so 468,119 < 486,191

Answer:

which answer best describes this picture

Answer:

Y=-5x-4

Step-by-step explanation:

Answer:

the answer is 1,674

Step-by-step explanation:

because if 3hours in 558 miles you multiply the 3hours in 558miles and the answer is 1,674

Answer:

4c+6≤−10

4c+6−6≤−10−6 ... subtract 6

4c≤−16...divide both sides by 4

final: c≤−4

5c-3>2

5c-3>2...add 3

5c>5...divide by 5

c>1

Answer:

The village market

Step-by-step explanation:

Price per can at the village market

= 2.30÷5

= $0.46

Price per can at Best Food

=5.10÷10

= $0.51

Answer:

Village market

Step-by-step explanation:

Find the unit rate at village market and Best food and compare.

Village market:

Rate per can  = 2.30 ÷ 5

                      = $ 0.46

Best food:

Rate per can = 5.10 ÷ 10

                     = 0.51

0.46 < 0.51

Buying can from village market is best buy as that is less priced
