What is the total number of digits you need to number the pages of a book that has 1450 pages?
Answer: pages 1-1,450
pages 1-9 = 9 digits
pages 10-99 = 90*2 = 180 digits
pages 100-999 = 900*3 = 2,700 digits
pages 1000-1450 = 451*4 = 1,804 digits
sum = 4,693 digits
Find the surface area of the prism.
Answer:
158 in²
Step-by-step explanation:
Surface area of a rectangular prism:
2(lw + lh + wh), where w is the width, l is the length and h is the height.
= 2((8 x 5) + (8 x 3) + (5 x 3))
= 2(40 + 24 + 15)
= 2(79)
= 158 in²
Sancho paints the new sign for his bike shop. One quart of paint covers 200 square
feet, and Sancho plans on applying three coats of paint. One quart of paint cost
$8.97. What is the square footage of his sign and ow much must Sancho spend to
paint the sign?
Slit the shape into a rectangle and two triangles:
Rectangle = 9 x 8 = 72 sq. Ft.
Triangle = 1/2 x 8 x 2.5 = 10 sq. Ft x 2 = 20 sq. Ft.
Total area = 72 + 20 = 92 sq. Ft.
3 coats x 92 = 276 sq ft worth of paint.
1 quart covers 200 so he would need to buy 2 quarts:
2 x $8.97 = $17.94 total

You work 44 hours at Candelaria's Tortilla Factory (CTF), You earn $15.00 per hour and you get paid 1.5 times
your base rate for hours worked over 40 hours. You pay 6.25% for Social Security, and 1.45% for Medicare.
You also pay $83.00 for your health insurance. You also put 3% of your gross pay into 401(k). How much is
your take home pay?
Answer:
$537.87
Step-by-step explanation:
First, we need to determine our total pay which will be 40 hours times our $15 per hour to be $600. For the extra hours above 40, we are payed 1.5 times as much.
$15 * 1.5 = $22.5 * (44-40) = $90 additional pay
$600 + $90 = $690 total pay
Now, we calculate all of our deductions.
Subtract social security to be
690 * (1-0.0625) = $646.875
Medicare Deduction
646.875 * 0.9855 = $637.50
Health Insurance
$637.50-83 = $554.50
401k Deduction
$554.50 * 0.97 = $537.87

Using proportions to solve for missing sides.
DGH~DEF
Find the value of x.
Answer:
25
Step-by-step explanation:
If ΔDGH ~ ΔDEF , then [tex]\frac{DG}{DE}[/tex] = [tex]\frac{GH}{EF}[/tex]
[tex]\frac{x+3}{2x-1}[/tex] = [tex]\frac{52}{91}[/tex]
After cross-multiplication: 52(2x - 1) = 91(x + 3)
104x - 52 = 91x + 273
13x = 325
x = 25
Answer:
x = 25Step-by-step explanation:
DGH~DEF ⇒ their corresponding sides are proportional
then
[tex]\frac{DG}{DE} =\frac{GH}{EF}[/tex]
then
[tex]\frac{52}{91} =\frac{x+3}{2x-1}[/tex]
then
[tex]\frac{4}{7} =\frac{x+3}{2x-1}[/tex]
then
4(2x-1) = 7(x+3) [cross multiply]
then
8x - 4 = 7x + 21
then
8x - 7x = 21 + 4
then
x = 25

6x + y=4x+ 11y, write a formula for h(x) in terms of x
Answer:
[tex]h(x)=\frac{1}{5}x[/tex]
Step-by-step explanation:
To write a formula for a function, such as h(x), you need to solve for y.
[tex]6x+y=4x+11y[/tex]
[tex]-4x[/tex] [tex]-4x[/tex]
[tex]2x+y=11y[/tex]
[tex]-y[/tex] [tex]-y[/tex]
[tex]2x=10y[/tex]
[tex]/10[/tex] [tex]/10[/tex]
[tex]\frac{2}{10}x=y[/tex]
[tex]y=\frac{1}{5}x[/tex]
y and h(x) mean the same thing, so you can subsitute h(x) for y in order to fit the question.
Therefore, [tex]h(x)=\frac{1}{5}x[/tex]
Convert 6 2/3 % to a fraction lowest terms
Answer:
109/150
Step-by-step explanation:
Answer: 109/150
6% = 6/100
6/100 = 18/300 (Multiply Numerator and Denominator by 3)
2/3 = 200/300 (Multiply Numerator and Denominator by 100)
200/300 + 18/300 = 218/300
218/300 = 109/150 (Simplify by Dividing Numerator and Denominator by 2)

Angle sum property of triangle: Sum of all angles of triangle is 180
∠P + ∠Q + ∠R = 180
10x - 4 +4x - 22 + x +11 = 180
10x + 4x + x - 4 - 22 + 11 = 180
Combine like terms,
15x - 15 = 180
Add 15 to both sides
15x = 180 + 15
15x = 195
Divide both sides by 15
x = 195/15
x = 13
∠P = 10x - 4
= 10*13 - 4
= 130 -4
∠p = 126°

Key Takeaways. The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean.
The slopes of perpendicular lines are ___ ___of each other, which means their products is -1.
A. fractional reciprocals
B. negative reciprocals
C. positive reciprocals
Answer:
Negative Reciprocals
Step-by-step explanation:
Consider two slopes being perpendicular to each other:
[tex]\displaystyle \large{m_1\cdot m_2=-1}[/tex]
You will either receive:
[tex]\displaystyle \large{m_1=-\dfrac{1}{m_2}}[/tex]
or:
[tex]\displaystyle \large{m_2=-\dfrac{1}{m_1}}[/tex]
Say, you want to find perpendicular slope of 4. You have first slope as 4 and another as unknown which is assigned as m variable:
[tex]\displaystyle \large{4m=-1}\\\displaystyle \large{m=-\dfrac{1}{4}}[/tex]
Therefore, 4 and -1/4 are perpendicular to each other. See that one slope is positives while another is negative. If you have negative slope then the perpendicular slope is positive.
Hence, they are indeed reciprocal but also negative as well.

given : PK and PL - tangent
KM perpendicular KP
angle KML = 50°
Solve - angle KPL
Please help me with how to solve this, thanks!
Answer:
∠KPL = 80°
Step-by-step explanation:
As KM is perpendicular to KP, this means that KM is the diameter of the circle, as the tangent of a circle is always perpendicular to the radius.
The angle at the circumference in a semicircle is always a right angle. So if KM is the diameter then ΔKLM is a right triangle with ∠KLM = 90°
The sum of the interior angles of a triangle is 180°.
Therefore, ∠KLM + ∠KML + ∠LKM = 180°
As ∠KLM = 90° and ∠KML = 50°
⇒ 90° + 50° + ∠LKM = 180°
⇒ ∠LKM = 40°
As ∠PKM = 90° then
⇒ ∠PKL = 90 - ∠LKM
= 90 - 40
= 50°
Tangents from a common point to a circle are always equal in length, so as PK and PL are tangents from point P, then PK = PL
Therefore, ΔLPK is an isoceles triangle and so its base angles ∠PKL and ∠PLK will be equal.
Since ∠PKL = 50° then ∠PLK = 50°
Again, as the sum of interior angles of a triangle is 180°:
⇒ ∠KPL + ∠PKL + ∠PLK = 180°
⇒ ∠KPL + 50° + 50° = 180°
⇒ ∠KPL = 80°
