what's the value of x and y?
Answers
Answer:
x = 55
y = 70
Step-by-step explanation:
since it's all sides are equal its an equilateral triangle
each angle of an equilateral triangle is 60°
therefore,
y - 10 = 60 => y = 60 + 10
y = 70
x + 5 = 60 => x = 60 - 5
x = 55
Answer:
x+5=y-10
x-y = -15
y-10+X+5+X+5=180
2x+y =180
x-y+2x+y =180-15
3x.=165
x. =55
2x+y =180
y =180-(110)
y =70

Answer:
[tex]P (Yes | Nebraska) = 0.10[/tex]
Step-by-step explanation:
Given
See attachment for contingency table
Required
[tex]P (Yes | Nebraska)[/tex]
From the contingency table, we have:
[tex]P (Yes\ n\ Nebraska) = 0.044[/tex]
[tex]P (No\ n\ Nebraska) = 0.400[/tex]
The required can be represented as:
[tex]P (Yes | Nebraska) = \frac{P(Yes\ n\ Nebraska)}{P(Nebraska)}[/tex]
Where
[tex]P (Nebraska) = P (No\ n\ Nebraska) +P (Yes\ n\ Nebraska)[/tex]
So, we have:
[tex]P (Nebraska) = 0.400 + 0.044[/tex]
[tex]P (Nebraska) = 0.444[/tex]
So, we have:
[tex]P (Yes | Nebraska) = \frac{P(Yes\ n\ Nebraska)}{P(Nebraska)}[/tex]
[tex]P (Yes | Nebraska) = \frac{0.044}{0.444}[/tex]
[tex]P (Yes | Nebraska) = 0.10[/tex] --- approximated

Solve the following system of equations using Substitution, showing all work.
y= 2x + 3
2x + 5y = 3
Answers
Answer: (x,y) = (-1, 1)
This means that x = -1 and y = 1
========================================================
Explanation:
The first equation says that y is the same as 2x+3
That allows us to substitute y for 2x+3 in the second equation like so:
2x+5y = 3
2x+5( y ) = 3
2x + 5(2x+3) = 3 .... y replaced with 2x+3
2x+10x+15 = 3
12x+15 = 3
12x = 3-15
12x = -12
x = -12/12
x = -1
Then we'll substitute this into the first equation to find y
y = 2x+3
y = 2(-1) + 3 .... x replaced with -1
y = -2+3
y = 1
Together x = -1 and y = 1 pair up to form the ordered pair solution (x,y) = (-1,1)
If you were to graph y = 2x+3 and 2x+5y=3 on the same xy grid, then you should see that the two lines intersect at the location (-1,1). This is a visual way to determine the solution quickly through use of a graphing calculator.

Anna's class has already collected 74 cans for the annual canned food drive. Her class
must collect more than 200 cans to reach their goal. The class plans to collect 15 cans
each day. Which inequality shows the number of additional days, d, Anna's class
needs to reach the goal?
CLEAR
15d + 74 > 200
15d - 74 > 200
15d + 74 > 200
150 – 74 > 200
Answers
Answer:
15d + 74 > 200
d > 8.4 days
Step-by-step explanation:
Total cans needed = over 200
Number of cans they have = 74
Number of cans needed per day = 15
Number of days = d
The inequality is
74 + 15d > 200
Also written as
15d + 74 > 200
15d > 200 - 74
15d > 126
d > 126/15
d > 8.4 days
Answer:
15d + 74 > 200
d > 8.4 days
Step-by-step explanation:
Total cans needed = over 200
Number of cans they have = 74
Number of cans needed per day = 15
Number of days = d
The inequality is
74 + 15d > 200
Also written as
15d + 74 > 200
15d > 200 - 74
15d > 126
d > 126/15
d > 8.4 days

A cone has a radius of 5 cm and a height of 12 cm. What is the volume of the cone rounded to the tenth? Use pi = 3.14
Answers
Answer:
942m^3
Step-by-step explanation:
Given data
Radius of cone= 5m
Height= 12 m
We know that volume of a cone is given as
V= πr^2h
V= 3.14*5^2*12
V= 3.14*25*12
V= 942 m^3
Hence the volume is 942m^3
