In square ABCD, AC = 6x + 10, and BD = 10x + 2. What is the length of AC?
Hint: Diagonals are congruent, hence AC = BD
A)11
B)22
C)3.5
D)2
Answers
Answer:
B) 22
Step-by-step explanation:
AC = BD
6x+10 = 10x+2
simplify:
subtract 6x and 2 from both sides:
4x = 8
x = 2
then:
AC = 6(2)+10 = 22

Coordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define System
4x + 2y = -1
3x + 4y = 3
Step 2: Rewrite System
4x + 2y = -1
[Multiplication Property of Equality] Multiply -2 on both sides: -2(4x + 2y) = 2[Distributive Property] Distribute -2 on both sides: -8x - 4y = 2Step 3: Redefine Systems
-8x - 4y = 2
3x + 4y = 3
Step 4: Solve for x
Combine equations: -5x = 5[Division Property of Equality] Divide -5 on both sides: x = -1Step 5: Solve for y
Substitute in x [Original Equation]: 3(-1) + 4y = 3Multiply: -3 + 4y = 3[Addition Property of Equality] Add 3 on both sides: 4y = 6[Division Property of Equality] Divide 4 on both sides: y = 3/2A store buys paper at $15 per bundle.

Answer:
218.665
Step-by-step explanation:
Separate by shape, find the areas of the triangles first, so (10.1 x w)/2 To get the missing side you do 30.5-21.4=9.1. then divide that by 2 because you have 2 lines (triangles) that aren't part of the 21.4. After you find the area for the one triangle (10.1 x 4.55)/2=22.9775, multiply by 2 to get the combined area of both triangles. Next step is to find the area of the rectangle, which is just 21.4 x 30.5=216.14. Add all the areas, 45.955+216.14=262.095. Last step is to subtract the area of the shaded region, the rhombus, which is just diagonal x diagonal / 2. so (8.6 x 10.1)/2=43.43. 262.095-43.43=218.665.

Answer:
Step-by-step explanation:
1). 3x(2x - 2) = 3x(2x) + 3x(-2) [By distributive property]
2). x²(_ + 5x - 3) = (3)x² + x²(5x) + x²(-3)
3). _(x² - 3x + _) = x(x²) - (x)(-3x) + (x)(2)
4). (2x + 9)(x + 2) = 2x(x + 2) + 9(x + 2)
= 2x² + 4x + 9x + 18
= 2x² + 13x + 18
5). (z - 4)(2z + 1) = z(2z + 1) + (-4)(2z + 1)
= 2z² + z - 8z - 4
= 2z² - 7z - 4
10. A manufacturer makes conical funnels for
professional painters. The funnels are
formed from plastic with a 9-inch
diameter base and a height of 9 inches.
After the cones cool, a machine cuts off
1 inch of the tip to leave a 1-inch
diameter hole in the end. What is the
volume of the funnel? Show your work.
Answers
Answer:
The volume of the cone after the tip is cut off equals 150 cubic inches
Step-by-step explanation:
The dimensions of the cone formed from the funnel are given as height equals 9 inches and, radius equals 4 inches (radius = 8/2).
The volume of a cone is determined as follows;
Volume = πr²h/3
Volume = π x 4² x (9/3)
Volume = π x 16 x 3
Volume = 48π
When a portion of the cone is cut off from the tip, the height from the cut off part is 1 inch and the radius is 0.5 inch (radius = 1/2).
The volume of the cut off portion can now be calculated as;
Volume = πr²h/3
Volume = π x 0.5² x (3/3)
Volume = π x 0.25 x 1
Volume = 0.25π
Hence the volume of the cone after the tip has been cut off is now derived as follows;
Volume = 48π - 0.25π
Volume = 47.75π
Volume = 47.75 x 3.14
Volume = 149.935
Volume ≈ 150 cubic inches (Rounded to the nearest whole number)
I hope this helps :)

Lisa is planning for a party. She receives quotes from two party planners. Choice A quotes $18 per guest, plus $100 for renting the party hall. Choice B quotes $15 per guest, plus $160 for renting the party hall. Which inequality represents the number of guests Lisa can invite, if choice A were to cost less than choice B?
Answers
Answer:
x<20
Step-by-step explanation:
Building linear functions for each situation, the inequality is:
[tex]18x + 100 < 15x + 160[/tex]
------------------
Choice A:
$18 per guest.$100 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_a(x) = 18x + 100[/tex]
Choice B:
$15 per guest.$160 for renting.Thus, the cost of inviting x guests is given by:
[tex]C_b(x) = 15x + 160[/tex]
A cost less than B, thus, the inequality is:
[tex]C_a(x) < C_b(x)[/tex]
[tex]18x + 100 < 15x + 160[/tex]

Sixty percent of the marbles in a bag are blue. One marble is chosen and replaced. A second marble is chosen and replaced. Then a third marble is chosen. What is the probability that a blue marble will not be chosen?
Answers
Answer:
0.064. same as 8/125
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the total outcome.
Given that Sixty percent of the marbles in a bag are blue
The probability of picking a blue marble
p(b) = 60% = 3/5
The probability of not picking a blue marble
np(b) = 1 - 60%
= 1 - 3/5
= 2/5
Hence where 3 marbles are picked and replaced, the probability of not picking a blue marble
= 2/5 * 2/5 * 2/5
= 8/125
= 0.064
