Answer:
x = 6
y = -9
Step-by-step explanation:
The easiest way is to eliminate y by multiplying equation (2) by -2 and adding to equation (1)
(1) 7x + 2y = 24 (2) 4x + y = 15
- 8x - 2y = -30 -8x - 2y = -30
-x = - 6
x = 6 4(6) + y = 15
24 + y = 15
y = - 9

Step-by-step explanation:
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?
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]

A square 10cm on each side has four quarter circles drawn with centers at the four corners. How many square centimeters are in the area of the shaded region? Express your answer in terms of $\pi$.
Answer:The answer is 100-25pi
Step-by-step explanation:
quarter circles = full circle
Full circle area = pie r2
Square area = s2
In this case, the side of the square is twice the radius of the circle

Its a right angle triangle with the values of its adjacent and hypotenuse given so cos is used.
HELPPPPPPPPPP PLEASEEEEEEEEEEEEE !!!!!
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.
What is the radius of a circle with circumference of 50 cm? Round your answer to the nearest whole number. Use π = 3.14.
A. 4 cm
B. 3 cm
C. 8 cm
D. 7 cm
Answer:
8 is the answer
Step-by-step explanation:
the equation is r = C/2*3.14
2*3.14=6.28
Because your C is 50 you do 50/6.28 and when you do that you get 7.962 (rounded) and then we round for the whole # so 8.

a equivalent or odd number between 90 and 180
Answer:
That means from 80 to 90, there are 5 odd numbers.
That also means, in between 10 numbers, there are 5 odd numbers.
It's fair enough to believe now that in the next 20 numbers—80 to 100—there will be 10 odd numbers.
Another pattern.
And the conclusion: from 80 to 180, there are 100 numbers. Therefore, There Will Be 50 Odd Numbers.
There are 50 odd numbers between 80 and 180.

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

y=1/3x -4
Step-by-step explanation:
3y-x=-12
y= 1/3x-4
m=1/3
(gradient is the same since its parallel)
y=mX+c
(2) = 1/3(18) + c
2 = 6 + c
2 - 6 = c
c= -4
(y-intercept)
Therefore: y=1/3x-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.
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)

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
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

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?
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
