Answer:

2650

Step-by-step explanation:

Ok so,

3000-(3.5(100))

3.5 multiplied by 100 is 350, (move the decimal place 2 times to the right)

so it would be:

3000-350

Simply subtract.

3000-350= 2650

Answer: 2650

Answer:

None of these could be a 60-30 right triangle

Step-by-step explanation:

A)  is a 45-45 right triangle and the hypotenuse is too short

                        a² + b² = c²         2² + 2² ≠ 3²

B)  13 is way too long

C)  32 too long    3² + 3² ≠ 32²    

D) really 613 no way

Answer:

72.5°

Step-by-step explanation:

180° - 35° = 2y°

145° = 2y

145/2 = 50+22+0.5 = 72.5

Using SOHCAHTOA [tex]cos=\frac{opposite}{hypotenuse}[/tex]

So CosA=D

Answer:

angle 6 and angle 3

Step-by-step explanation:

angle 1 and angle 6 add up to 90 degrees

angle 6 is vertical to angle 3, so 1 is complementary to 3 as well

Answer:

(a) 20 represents the initial population and

    1.014 represents 1 + % growth of rabbits each day

(b) Average Rate of change = 0.8

Step-by-step explanation:

P.S - The exact question is -

Given - A population of rabbits in a lab, p(x), can be modeled by

            the function p(x)=20(1.014)^x, where x represents the number

            of days since the population was first counted.

To find - (a) Explain what 20 and 1.014 represent in the context of

                   the problem.

              (b) Determine, to the nearest tenth, the average rate of

                   change from day 50 to day 100.

Proof -

(a)

Given that the function p(x) is represented as

[tex]p(x) = 20(1.014)^{x}[/tex]

Here,

20 represents the initial population and

1.014 represents 1 + % growth of rabbits each day

(b)

Given,

[tex]p(x) = 20(1.014)^{x}[/tex]

When x = 50

[tex]p(50) = 20(1.014)^{50}[/tex] = 40.08000 ≈ 40.1

When x = 100

[tex]p(100) = 20(1.014)^{100}[/tex] = 80.32033 ≈ 80.3

Now,

Average Rate of change = [tex]\frac{p(100) - p(50)}{100 - 50}[/tex]

                                         = [tex]\frac{80.3 - 40.1}{50}[/tex]

                                         = [tex]\frac{40.2}{50}[/tex]

                                         = 0.804 ≈ 0.8

⇒Average Rate of change = 0.8

Answer:

9/4 pounds of walnut

Step-by-step explanation:

First we divide 11.25/3.75=3 so we would know how many 3/4 pounds are there. Then, we know there are 3-3/4 pounds of walnuts. Mulitply them, you will get 9/4

Answer:

3 18/25

Step-by-step explanation:

Rewrite as [tex]3\frac{72}{100}[/tex]

Simplify 72/100. The greatest common factor of 72 and 100 is 4

72 / 4 = 18

100 / 4 = 25

Final answer:

[tex]3\frac{18}{25}[/tex]

Answer:

I think that there is a limit on the number of times  you can withdraw or transfer money in your savings account because banks only maintain a small percentage of the money people deposit on the savings accounts and most of the money is used for loans and they need to limit that to be able to have enough reserves to cover the withdrawals. If they don't put a limit people can try to withdraw all the money at the same time and the bank would not have the funds to cover that.

Answer:

20 gray squares

Step-by-step explanation:

Given

See attachment for squares

Required

Number of gray squares when white = 16

First, we calculate the equation that represents both squares.

The white squares

[tex]a = 2[/tex] --- initial

[tex]d = 4 - 2 = 6 - 4[/tex]

[tex]d = 2[/tex] -- difference between successive gray squares

So, the nth term is:

[tex]W_n = a + (n - 1)d[/tex]

[tex]W_n = 2 + (n - 1)*2[/tex]

[tex]W_n = 2 + 2n - 2[/tex]

[tex]W_n = 2n[/tex]

The gray squares

[tex]a = 6[/tex] --- initial

[tex]d = 8-6=10-8[/tex]

[tex]d = 2[/tex] -- difference between successive gray squares

So, the nth term is:

[tex]G_n = a + (n - 1)d[/tex]

[tex]G_n = 6 + (n - 1) *2[/tex]

[tex]G_n = 6 + 2n - 2[/tex]

[tex]G_n = 4 + 2n[/tex]

When the white squares is 16

[tex]W_n = 16[/tex] --- Calculate n

[tex]W_n = 2n[/tex]

[tex]16 = 2n[/tex]

[tex]8 = n[/tex]

[tex]n = 8[/tex]

To get the number of gray squares;

Substitute [tex]n = 8[/tex] in [tex]G_n = 4 + 2n[/tex]

[tex]G_n = 4 + 2 * 8[/tex]

[tex]G_n = 20[/tex]

Answer:

The answer is "Rotation and dilation".

Step-by-step explanation:

The rotation is a spatial movement, which maintains at least one stage. The dilation of a transition affects a figure's dimensions. The center, as well as a scale factor k, are required Which meaning k determines if the expansion is an expansion or a decrease, therefore the above choice is correct because it just rotated and dilated from its original form.

Step-by-step explanation:

Answer:

the answer is 216 sq cm.

Step-by-step explanation:

Do 12×14=168. Then 12×8=96. Then 96/2=48. Then add 168+48=216.

Answer:

216

Step-by-step explanation:

12x 14=168

8x12=96

96/2=48

168+48=216

Answer:

[tex]y=[/tex] [tex]-\frac{5}{6}x - 1[/tex] is the answer

Step-by-step explanation:

Equation of the line: y = 6/5x + 1

                        = 5y = 6x + 5

                        = 6x - 5y + 5

Equation of the perpendicular line: bx - ay + k = 0

                                                       = -5x -6y + k = 0

Equation passes through (6,-6),

-5(6) -6(-6) + k = 0

-30 + 36 + k = 0

6 + k = 0

k = -6

Substituting,

-5x -6y + k = 0

-5x -6y -6 = 0

-6y = 5x + 6

[tex]y=[/tex] [tex]-\frac{5}{6}x - 1[/tex] (Slope-Intercept form)

Answer:

(10/3, 1)

Step-by-step explanation:

Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)

The formula for calculating the coordinate of a point divided in the ratio a:b is expressed as;

X = ax1+bx2/a+b

Y = ay1+by2/a+b

Given the coordinates A(4,4) B(2,-5) divided in the ratio 2:1

X = 2(4)+1(2)/2+1

X = 8+2/3

X = 10/3

Similarly;

Y = 2(4)+1(-5)/2+1

Y = 8-5/3

Y = 3/3

Y = 1

Hence the required coordinate is (10/3, 1)

Given:

Normal price of a tv = $200

Coupon = 25% off

To find:

The money saved by Katherine.

Solution:

Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. It means, the money saved by Katherine is 25% of normal price of tv, i.e., $200.

[tex]Saving=25\%\text{ of }200[/tex]

[tex]Saving=\dfrac{25}{100}\times 200[/tex]

[tex]Saving=25\times 2[/tex]

[tex]Saving=50[/tex]

Therefore, the money saved by Katherine is $50.
