Answer:
Hey! Answer: F
Step-by-step explanation:
13.5 ÷ 9= 1.5
18 ÷ 12 = 1.5
So our pattern is to enlarge/multiply it by 1.5
So 1.5 x 15 = 22.5
So F is our answer!
What is the total number of digits required in numbering a book that has 1724 pages?
Answer:
5,789
Step-by-step explanation:
I got 5,789 because there are 9 one digit numbers. 1-9 -> 9x1=9. There are 90 two digit numbers. (10-99)-> 90x2=180. There are 900 three digit numbers. (100-999)-> 900x3=2700. There are 725 four digit numbers. (1000-1724)-> 724x4= 2900. Then, I added 9+180+2700+2900=5789.
In conclusion, the total number of digits required in numbering a book that has 1724 pages is 5789.
There are 5,789 digits in total required to number the pages of a book with 1,724 pages.
What is Numbering?A numbering is the assignment of natural numbers to a set of objects in some formal language, such as functions, rational numbers, graphs, or words, in computability theory.
Digits required in numbering a book that has 1724 pages?Given the total number of pages is 1,724
Let's break down the pages now to find the total digits.9
one-digit numbers (1-9) = 9 x 1 = 9 digits make up the number 1,724.90 numbers with two digits (10-99) = 90 x 2 = 180 digits900 three-digit numbers (from 100 to 999) = 900 times three = 2700 digits725 numbers with four digits (1000-1724) = 725 x 4 = 2900 digits
Let's add the digits now.9 + 180 + 2700 + 2900 = 5,789
As a result, the total number of digits required to number the pages of a 1,724-page book is 5,789.

Write an inequality that represents `t`, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning
Question:
At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour.
Write an inequality that represents t, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning.
Answer:
[tex]t > 4.5[/tex]
Step-by-step explanation:
Given
Let T = temperature and t = hours past midnight
So, we have:
[tex](t_1,T_1) = (0,5)[/tex] --- at midnight
[tex]m = -2[/tex] --- rate (it is negative because the temperature drops)
Required
Determine the inequality when the temperature is colder than -4 degrees
First, we calculate the hours when the temperature at -4 degrees
This is represented as:
[tex](t_2,T_2) = (t,-4)[/tex]
[tex](t_1,x_1) = (0,5)[/tex]
Using the slope formula, we have:
[tex]m = \frac{T_2 -T_1}{t_2 - t_1}[/tex]
[tex]-2 = \frac{-4-5}{t -0}[/tex]
[tex]-2 = \frac{-9}{t}[/tex]
Solve for t
[tex]t = \frac{-9}{-2}[/tex]
[tex]t = 4.5[/tex]
This implies that: at 4.5 hours, the temperature is at -4 degrees Celsius.
So, the inequality is:
[tex]t > 4.5[/tex]

Laura wants to cover a box with fabric.
• The box is in the shape of a rectangular prism.
• It measures 15 in. long, 11 in. wide, and 24 in. tall.
Answer:
Area of rectangular prism = 1,578 inch²
Step-by-step explanation:
Given:
Length of rectangular prism = 15 in
Width of rectangular prism = 11 in
Height of rectangular prism = 24 in
Find:
Total fabric need
Computation:
Total fabric need = Area of rectangular prism
Area of rectangular prism = 2[lb + bh + hl]
Area of rectangular prism = 2[(15)(11) + (11)(24) + (24)(15)]
Area of rectangular prism = 2[165 +264 + 360]
Area of rectangular prism = 2[789]
Area of rectangular prism = 1,578 inch²

Step-by-step explanation:
6^2 because,
6^1 is not a perfect square because 6 is its own number because 6 x 1 =6 Therefore being eliminated.
6^3 is not a perfect square because 6 x 6 x 6 (216) is cubed not square
*This one almost tricked me*
6^5 is not a perfect square because 6 x 6 x 6 x 6 x 6 (7776) it isn't an equal factor combination, that when multiplied together, produce the number 7,776. That means 7,776 is not a perfect square.
6^2 is a perfect square because 6x6= 36 and 36 is a perfect square.

take the derivative of the equation 4 times. f 4 (x)=0.
Step-by-step explanation:
if you put in the values (-1/2, 1/4, 2/5) in the function
{–8, –2, 18}
Step-by-step explanation:
y = 5x − 2
x = −1.2 > y = 5(−1.2) − 2 = −6 − 2 = −8
x = 0 > y = 5(0) − 2 = 0 − 2 = −2
x = 4 > y = 5(4) − 2 = 20 − 2 = 18
{-1/2, 1/4, 2/5}
Step-by-step explanation:
All you have to do is go on a graphic calculator and input the equation by pressing y= then after putting it in to y= all you have to do is press 2nd (the only blue button) and graph and that will show you all the points to that equation (also known as range and domain)
Hope this helps. :)
Domain is inputs, input the domain for x
y=5(-1.2)-2
y=-6-2
y=-8
y=5(0)-2
y=0-2
y=-2
y=5(4)-2
y=20-2
y=18
range is {-8, -2, 18}
For x = 0,
we substitute zero into the equation to find its y value like so:
y = 5x-2
y = 5(0)-2
y = -2
There you go.
Take the derivative of the equation 4 times. f 4 (x)=0.
Y = 5x – 2
domain. {–5, –1, 0, 2, 10}
x = -5 then y = 5(-5) – 2 = -27
x = -1 then y = 5(-1) – 2 = -7
x = 0 then y = 5(0) – 2 = -2
x = 2 then y = 5(2) – 2 = 8
x = 10 then y = 5(10) – 2 = 48
answer

If p(t)=5t4+17t3–8t2+13t–12, use synthetic division to find p( – 4).
Answer:
the value of this function p(t) at t = -4 is also 0
Step-by-step explanation:
Recall that synthetic division in a problem such as this one returns a remainder, which is sometimes zero and is sometimes not. If not, then the remainder is the value of the given polynomial when evaluated at a given argument. We are to determine the remainder here when t = -4:
Setting up synthetic division:
-4 / 5 17 -8 13 -12
-20 12 -16 12
------------------------------------
5 -3 4 -3 0
Since the remainder is 0, the value of this function p(t) at t = -4 is also 0.

Answer:
b) 41.6 square inches
Step-by-step explanation:
A regular hexagon is inscribed in a circle with a diameter of 8 inches.
Step 1
We find the radius
Radius = Diameter/2
= 8 inches/2 = 4 inches
a. What is the perimeter of the hexagon?
b. What is the area of the hexagon?
An hexagon has 6 sides
The number of angles in an hexagon is calculated as:
[(Number of sides - 2) x 180]
= (6 - 2) x 180 = 720 ÷ 6 = 120°
The hexagon into 6 equilateral triangles with 4 for each of its sides.
The area of one of the triangles:
Height = 2√3
- one triangle's area = (1/2)bh = (1/2)(4)(2√3) = 4√3
The area of the hexagon by multiplying the one triangle's area by 6:
6 x 4√3 = 24√3 square inches
= 41.569219382 square inches
Approximately = 41.6 square inches

ABCD is a parallelogram. If a CDA - 57 then BCD-_?
The diagram is not to scale.
133
57
114
123
Answer:
57
Step-by-step explanation:
It is given in the question that length CDA = 57.
Since the shape is a parallelogram, then we know that length AD=BC and AB=CD.
CDA = CD + AD
BCD = BC + CD
Since BC=AD and CD=CD
BCD = BC + CD is the same as CD + AD = CDA
Therefore BCD is the same length as CDA = 57
In other words, CDA is made up of a long side and a short side = 57
BCD is also made up of a long side and a short side, and since the longs sides are equal to each other and the short sides are also equal to each other in a parallelogram, BCD is the same length as CDA = 57.
Hope this helped!
Can anyone solve this question??? plss plsss its my request to all if any one can solve this question I will mark him/ her the brainliest
Answer:
a) ∠EAB = 180° - 90° - 30° = 60°
∠EBA = 180° - 90° - 60° = 30°
a) ∠EBA = 30°
b) ∠DCA = 180° - 90° - 30° = 60°
∠EBA ≅ ∠DAC, ∠EAB ≅ ∠DCA, ∠AEB ≅ ∠CDA
ΔEBA ≅ ΔDAC because of the AAA postulate
c) EB ≅ DA, EA ≅ DC, AB ≅ CA
d) AB = CA given
sin ∠EAB = EB/AB (sin 60°) EB = (0.8660)AB
cos ∠EAB = EA/AB (cos 60°) EA = (0.5)AB
cos ∠DAC = AD/CA (cos 30°) AD = (0.8660)CA
sin ∠DAC = CD/CA (sin 30°) CD = (0.5)CA
ED = EA + AD
ED = (0.5)AB + (0.8660)CA
since AB = CA, ED = 1.366CA
since EB = (0.8660)AB and AB = CA, then EB = 0.866CA
since CD = 0.5CA,
EB + CD = 0.866CA + 0.5CA = 1.366CA
EB + CD = 1.366CA
1.366CA = 1.366CA
Proof: ED = EB + CD
