Jim can paint 5 chairs with 11.3 gallons of paint.
How many chairs can he paint with 24.86 gallons?
Answer: Jim can paint 11 chairs.
Step-by-step explanation: if 5 chairs is 11.3 then 10 chairs are 22.6 and if you want to know how much is on 24.86 you divide 11.3 with 5 because then you can add with 1 chair at a time which is 2.26 and then you add 2.26 which is exactly 24.86. 5+5+1 is 12. 5 chairs=11.3 10 chairs=22.6 11 chairs=24.86I need Help I don't understand
. A system may become infected by some spyware through the internet or e-mail. Seventy percent of the time the spyware arrives via the internet, thirty percent of the time via email. If it enters via the internet, the system detects it immediately with probability 0.6. If via e-mail, it is detected with probability 0.8. What percentage of times is this spyware detected
Answer:
This spyware is detected 66% of the time.
Step-by-step explanation:
We have these following percentages:
70% of the time, the spyware arrives via the internet, and in this case, is detected 60% of the time.
30% of the time, the spyware arrives via e-mail, and in this case, is detected 80% of the time.
What percentage of times is this spyware detected
Sum of 60% of 70%(arrived via spyware, detecte) and 80% of 30%(arrive via e-mail, detected). So
[tex]0.6*0.7 + 0.8*0.3 = 0.42 + 0.24 = 0.66[/tex]
This spyware is detected 66% of the time.

One side of triangle is 5 more than 3 times the shortest side. The third side is 24 feet more than the shortest side. The perimeter is 114 . Find all three sides.
Answer:
17, 56, 41,
Step-by-step explanation:
"third side is 24 more than shortest side"
Let a be the shortest side.
c = a+24
"perimeter is 114"
a+b+c = 114
a+b+(a+24) = 114
2a + b = 90
"one side is 5 more than 3 times the shortest side"
That side must be b; c is an extraneous solution.
b = 3a+5
2a+(3a+5) = 90
a = 17
b = 56
c = 41
(a,b,c) = (17,56,41)
consider the inequalities
y 2x + 3, which is true?
a. the line would be solid with shading above
b. the line with be duchess with shading above
c. the line would be solid with shading below
d. none of this
please answer this guys:-(
Answer:
The line with be duchess with shading below.
None of the above
Step-by-step explanation:
The correct inequality expression is;
y < 2x+3
Note that the inequality sign between the expressions is the one that will determine the nature of the line.
Since the sign is not containing the "equal to" sign this means that the line will be broken(duchess).
Since it is "less than", the shading will be below the line.
Considering the given option, None of the option is correct
For the inequalities
[tex]\rm\bold{ y < 2x+3 ......(1)} \\\\\rm \bold{y > 2x +3....(2)}}[/tex]
For Case (1)
Option d will be chosen as correct option
hence " none of these" will be the answer
For Case (2)
Option b will be chosen as correct option
hence " The line with be duchess with shading above " will be the answer
Since the sign of the inequality here is not clear let us consider 2 cases that are represented by equation (1) and equation (2)
[tex]\rm y < 2x+3 ......(1) \\y > 2x +3....(2)[/tex]
Considering case 1 as represented by equation (1)
The y values are always less than the expression for the line 2x+3 hence points on the line [tex]\rm y = 2x +3[/tex] will not be included for this inequality hence the line will be duchess with area below the line.
So in this case option d will be chosen as correct option
hence " none of these" will be the answer
Similarly now considering case 2 as represented by equation (2)
The y values are always more than the expression for the line 2x+3 hence
points on the line [tex]\rm y = 2x +3[/tex] will not be included for this inequality hence the line will be duchess with area above the line.
So in this case option b will be correct.
Note :
The lines will be solid when the inequalities in equation (1) and (2) also include equal to sign.
That is for lines to be solid
the inequalities will be of type
[tex]\rm y \leq 2x+3 \\y \geq 2x +3[/tex]

A triangle has an area of 29.7cm^2 and a base of 13.5cm. Use the formula A=1/2 bh to find the height.
Answer:
4.3362962963
Step-by-step explanation:
A=1/2bh
29.7cm^2=1/2 13.5h
You're gonna multiply each side by 2 to cancel out the fraction equaling,
58.54= 13.5h
You're then gonna divide w=each side by 13.5 to get h left alone on one side and a number on the other equaling your answer. 4.3362962963. Round to whatever decimal place you need.

Find the perimeter of the triangle whose vertices are the following, specified points in the plane.
(-10,-3), (1,4) and (-1,7)
Given:
The vertices of the triangle are (-10,-3), (1,4) and (-1,7).
To find:
The perimeter of the triangle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Let the vertices of the triangle are A(-10,-3), B(1,4) and C(-1,7).
Using distance formula, we get
[tex]AB=\sqrt{(1-(-10))^2+(4-(-3))^2}[/tex]
[tex]AB=\sqrt{(1+10)^2+(4+3)^2}[/tex]
[tex]AB=\sqrt{(11)^2+(7)^2}[/tex]
[tex]AB=\sqrt{121+49}[/tex]
[tex]AB=\sqrt{170}[/tex]
Similarly,
[tex]BC=\sqrt{\left(-1-1\right)^2+\left(7-4\right)^2}=\sqrt{13}[/tex]
[tex]AC=\sqrt{\left(-1-\left(-10\right)\right)^2+\left(7-\left(-3\right)\right)^2} =\sqrt{181}[/tex]
Now, the perimeter of the triangle is
[tex]Perimeter=AB+BC+AC[/tex]
[tex]Perimeter=\sqrt{170}+\sqrt{13}+\sqrt{181}[/tex]
[tex]Perimeter\approx 13.038+3.606+13.454[/tex]
[tex]Perimeter=30.098[/tex]
Therefore, the perimeter of the triangle is 30.098 units.

Answer:
x = 8
Step-by-step explanation:
Let's solve your equation step-by-step.
−6+7x=50
Step 1: Simplify both sides of the equation.
7x−6=50
Step 2: Add 6 to both sides.
7x−6+6=50+6
7x=56
Step 3: Divide both sides by 7.
7x/7 = 56/7
x=8
