4.Find the measure of arc DF in the figure.

Answer:

4

Step-by-step explanation:

If Annie and her grandmother play with 5 of the puppies, subtract 5 from 53 to get 48. Since there are 12 volunteers, divide 48 by 12 to get 4. So, each volunteer plays with 4 puppies. My work is shown below.

53-5=48

48/12=4

PLEASE MARK ME AS BRAINLIEST

Answer: 4

Step-by-step explanation: Hi there

1. Subtract the number of puppies Annie plays with from the total number of puppies. 53-5=48

2. Divide the number of remaining puppies by the number of volunteers. 48/12=4

Therefore, each volunteer plays with 4 puppies.

Answer:

3.2%

Step-by-step explanation:

You want to find the area of the hole and the area of the board. The area of the board is 21x42 which is 882 inches squared. The circular hole has a radius of 3 inches so [tex]\pi[/tex]3² which is 9[tex]\pi[/tex].

Now put in calculator [tex]\frac{9\pi }{882}[/tex] which is pi over 98 which simplifies to 0.032.

To Factorize:

[tex]~[/tex]

Solution:

[tex] \: \: \: \: \sf \longrightarrow {x}^{2} - 10x + 24[/tex]

[tex] \: \: \: \: \sf \longrightarrow {x}^{2} - 4x - 6x + 24[/tex]

[tex] \: \: \: \: \sf \longrightarrow x(x - 4) - 6(x - 4)[/tex]

[tex] \: \: \: \: \sf \longrightarrow (x - 6)(x - 4)[/tex]

We are given with a quadratic equation and we have to factorise it , so let's proceed.

[tex]{:\implies \quad \sf x^{2}-10x+24}[/tex]

[tex]{:\implies \quad \sf x^{2}-6x-4x+24}[/tex]

[tex]{:\implies \quad \sf x(x-6)-4(x-6)}[/tex]

[tex]{:\implies \quad \bf \underline{\underline{(x-6)(x-4)}}}[/tex]

To factorise a quadratic polynomial ax² + bx + c we have to split it's middle term bx into say mx and nx and it will look like ax² + mx + nx + c ,also we should split it such that it follows the both conditions below :-

Answer:

313.9 m

Step-by-step explanation:

tan 36° = opp/adj

tan 36° = y/430

y = 430 tan 36°

y = 312.4

height = 1.5 + 312.4 = 313.9

Answer: 313.9 m

Answer:

313.9

Step-by-step explanation:

First use  trigonometric ratio of tan   .

consider the angle to be  36 .

base of the triangle to be 430  .

consider the perpendicular to be the height of the tower from the eye level of Jean to the top.  let's take it is   x  

the formula will be      tan  36  = x /430

find x  by using  tan  36    =  0.73   and multiplying this by  430  

it will be 312.4

adding the height of jean  1.5     .

total height of the tower is     313.9

Answer:

y-intercept is (0, −2)

x-intercept is (2/3, 0)

Step-by-step explanation:

y=3x-2

y=mx+c (m is the gradient and c is the y-intercept)

Therefore, the y-intercept is (0, −2)

To determine the x-intercept, we set y equal to zero and solve for x.

So, 0=3x-2. We can rearrange this... 2=3x therefore x=2/3

The x-intercept is (2/3, 0)

Hope this helps!

Answer:22

Step-by-step explanation:

By analyzing the population equation we can see that:

Here we have the population equation:

[tex]p(t) = \frac{500}{1 + 4.55e^{-0.5*t}}[/tex]

a) When does the growth rate start to decrease?

The rate of change will be:

[tex]p'(t) = 0.5*\frac{500}{(1 + 4.55e^{-0.5*t})^2}*4.55e^{-0.5*t}[/tex]

Below, you can see the graph of it, and there you can see that for t > 0 the rate always decreases.

b) The initial population is what we get when we evaluate p(t) in t = 0

[tex]p(t) = \frac{500}{1 + 4.55e^{-0.5*0}} = \frac{500}{1 + 4.55} = 91[/tex]

c) What is the maximum population?

It is 500 (asymptotically), which is the value that we get when we take the limit of t to infinity.

d) The population after 2 years is given by:

[tex]p(t) = \frac{500}{1 + 4.55e^{-0.5*2}} = 187[/tex]

So after two years, there will be 187 birds.

Answer:

c

Step-by-step explanation:

Answer:

This statement is true.

Step-by-step explanation:

The absolute value is how far the number is from zero, so how many steps will it take on a number line to get from that particular number to zero?

Since you can't have negative steps, The -13 in absolute value would be 13.

The -(-13) is the same thing as saying  -1 ( -13 ). Since negative times a negative is a positive, 13=13 is a true statement.

Answer:

1,25/0,75

Step-by-step explanation:

3/4 = 0.75

5/4= 1.25

Answer:

One. See why ↓

5/4 is an improper fraction. We want a mixed number where the numerator is greater than the denominator for this to be right, so convert 5/4 to 1 1/4.

Typically speaking, there is only 1 of 3/4 in 5/4.

Therefore,

There is 1 of 3/4 in the number, 5/4.

Answer: The area of the shaded region is 30 cm^2

Step-by-step explanation:

First, we recall the area for a rectangle and a triangle.

-Area for rectangle: A = L x W

-Area for triangle: A = 1/2 x b*h

Next, I find the area of the total region.

-12 cm x 4 cm = 48 cm^2

Then, I find the area for the non-shaded region (or the white triangle)

- A= 1/2 x 9*4

- A= 1/2 x 36

- A = 18 cm^2

Finally, I subtract the total area of the whole region from the non-shaded region ( or again white triangle)

- 48 minus 18 = 30 cm ^2

Step-by-step explanation:

Add a 0.

The ones are of lesser value because they only have one whole number, and the 16.099 is less than 16.40 because it has that 0 in front of the nines.
