Ms. Neil has 25% of her class who have turned in their reading logs. 7 students have
turned in their logs. Enter the total number of students in her class.

Given:

Consider the below figure attached with this question.

To find:

The per perimeter of the isosceles trapezoid. Round all figures to the nearest hundredths place.

Solution:

Consider the isosceles trapezoid is ABCD.

Draw two perpendicular from C and D to  AB as shown in second figure.

Now, CDEF is a rectangle,

[tex]EF=CD=9\text{ ft}[/tex]

[tex]AB-EF=13-9[/tex]

[tex]AB-EF=4\text{ ft}[/tex]

It is an isosceles trapezoid, so [tex]\Delta ADE\cong \Delta BCF[/tex].

[tex]AE=BF=\dfrac{4}{2}=2\text{ ft}[/tex]

Now,

[tex]AE^2+DE^2=AD^2[/tex]         [Pythagoras theorem]

[tex]2^2+4^2=AD^2[/tex]

[tex]4+16=AD^2[/tex]

[tex]\sqrt{20}=AD[/tex]

[tex]AD=BC\approx 30.94[/tex]          [Isosceles trapezoid]

Find the perimeter of the figure.

[tex]Perimeter=AB+BC+CD+AD[/tex]

[tex]Perimeter=13+4.47+9+4.47[/tex]

[tex]Perimeter=30.94\text{ ft}[/tex]

Therefore, the correct option is c.

Shorter Version: C lol

Answer:

f(5) is equal to 5.

Step-by-step explanation:

You can see this by looking at 5 on the horizontal axis, and seeing where the graph crosses vertical line for that value.  If you look closely, you'll see that the x value of 5 has a y value of 5 as well.

Answer:

3 - 5 = -2

Step-by-step explanation:

Cause 3 is lower than 5

And since 5 - 3 = 2

If it's the other way around it's a negative number

Answer:

3

Step-by-step explanation:

Start from 0 and do 3 minus 5 which gets you -2

Answer:

85°

Step-by-step explanation:

So in geometry, the formula to find the sum of all interior angles is denoted as follows:

n = number of sides in the polygon

( n - 2 ) × 180° = sum of the interior angles

Using that formula, a triangle has 3 sides, so

n = 3 , therefore:

= ( 3 - 2 ) × 180°

= 1 × 180°

= 180°

Since the total sum of the interior angles of a triangle all have to add up to 180°, you can create the following equation and solve:

34° + 61° + x = 180°

Solve for x.

Answer: It's the third one down

Step-by-step explanation:

Answer:The total cost, C, is the sum of the cost to produce the centerpieces and the fixed cost. The equation for C is C = 8n + 500.

The total revenue, R, of Julio's floral business is the product of the cost per centerpiece and the number of centerpieces sold. The equation for R is R = 19.50n.

Step-by-step explanation:

11.2/2.75=4.07272(repeating number)

Answer:

11 1/5 divided by 2 3/4:

11 1/5 is a bit less than 12, and 2 3/4 is a bit less than 3

The answer, therefore, should be fairly close to 12 ÷ 3

12 ÷ 3 is 4

Answer is 4

Answer:

To run one lap Lin takes 1.6 minutes.

Step-by-step explanation:

To find this answer you would do 8 divided by 5. Always remember when dividing time goes first unless the instructions / directions / your teacher says differently. So, when you do 8 divided by 5 the answer you get is 1.6, and there is your answer. Also to check your answer you can do 1.6 times 5, and you get 8, so you know that 1.6 is the correct answer.

Step-by-step explanation:

10/33

Answer:

10 : 33

Step-by-step explanation:

Both 20 and 66 are multiples of 2.

20 = 2 x 10

66 = 2 x 33

So, this ratio becomes 2 x 10: 2 x 33

Dividing both sides by 2 gives us 10:33, which can't be simplified further.

Answer:

Yes

Step-by-step explanation:

3.t can be written as a fraction, which is 7/2, so yes it is a rational number.

Answer:

C = 133.33°

Step-by-step explanation:

Apply the Law of Cosines to find angle C:

[tex] Cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex]

Where,

a = 8.5 cm

b = 4.1 cm

c = 11.7 cm

Plug in the values

[tex] Cos(C) = \frac{8.5^2 + 4.1^2 - 11.7^2}{2*8.5*4.1} [/tex]

[tex] Cos(C) = \frac{-47.83}{69.7} [/tex]

[tex] Cos(C) = -0.6862 [/tex]

[tex] C = Cos^{-1}(-0.6862) [/tex]

C = 133.33°

Answer:

Scale factor = 1.5

Step-by-step explanation:

Formula for the scale factor,

Scale factor = [tex]\frac{\text{Measure of one side of the Image}}{\text{Measure of one side of the preimage}}[/tex]

In this question, image is triangle Y and preimage is triangle X.

Scale factor of X to Y = [tex]\frac{15}{10}[/tex]

                                    = 1.5

Therefore, scale factor = 1.5 is the answer.
