Solve for x.
18+x=y
x = 0
?
Answer:
The answer is 18
Step-by-step explanation:
18 + x really means 18 + 0, because x is equal to 0
and if 18 + x = y, it means 18 + 0 = y,
so y is equal to 18

A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2
A customer calls your landscaping business already knowing the total area of a circular garden they are going to have landscaped. The area of the garden is 33.26 yards². For the work they are asking you to do, you need to calculate the radius. Remember to work the Area formula backwards to solve for the radius.
Answer:
Step-by-step explanation:
Area = πr²
πr² = 33.26
r = √(33.25/π) ≈ 3.25 yards

Answer:
x=1
Explanation:
3x+4*2x=11
(We move all terms to the left)
3x+4*2x-(11)=0
( We multiply elements )
3x+8x-11=0
(We add all the numbers together, and all the variables )
11x-11=0
( We move all terms containing x to the left, all other terms to the right )
11x=11
x=11÷11
x=1
A -foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a angle with a short vertical support.
Complete question :
A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.
What is the length x of a diagonal support, to the nearest tenth of a foot?
Answer:
13.80 feets
Step-by-step explanation:
Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :
To obtain x :
Sinθ = opposite / hypotenus
Opposite = 12.5 feets ; hypotenus = x ; θ = 65°
Sin 65 = 12.5 / x
0.9063077 * x = 12.5
x = 12.5 / 0.9063077
x = 13.792225
x = 13.80 feets
In ΔMNO, n = 92 inches, ∠N=119° and ∠O=20°. Find the length of m, to the nearest 10th of an inch.
Answer:
Step-by-step explanation:
The length of the side of the triangle will be 69 inches.
What is the sine law?The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.
The sine law in the triangle ΔMNO is given as,
n / sin N = m / sin M = o / sin O
The third angle is calculated as,
∠M + ∠N + ∠O = 180°
∠M + 119° + 20° = 180°
∠M = 41°
The length m is calculated as,
n / sin N = m / sin M
92 / sin 119° = m / sin 41°
m = 69 inches
The length of the side of the triangle will be 69 inches.

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
volume = 254.34 cubic inches
Step-by-step explanation:
r = diameter /2 = 6/2 = 3 in
h = 3 × r = 3 × 3 = 9
volume = pi× r^2 × h

Answer:
x = 13
Step-by-step explanation:
I created a proportion from similar sides HB ≈ LY and NH ≈ RL
28/21 = (3x - 7)/(x + 11)
then cross-multiply to get
28(x + 11) = 21(3x - 7)
28x + 308 = 63x - 147
28x = 63x - 455

Peter works two part time jobs. He is paid $6 er hour at job a and $9 per hour at job b. Last wee eter worked a total of 24 hours at both jobs and madr $189. Hobmny hours dud peter work at job a?
Answer: Peter worked 9 hours at job a
Step-by-step explanation:
Step 1
Let the number of hours worked in job a = x
and number of hours worked in job b = y such that the total hours worked would be expressed as
x=y= 24 ---eqn 1
also since $6 and $9 dollar are paid per hour for the job and the total amount made is $189, it should be expressed as
6x + 9y =$189--- equation 2
Step 2
Now we have gotten two expressions to solve for number of hours, we can now solve
x+y= 24 ---eqn 1
6x + 9y =$189--- eqn 2
Using elimination method, we multiply equation 1 by 6 and subtract from equation 2
6x + 9y =189
-6x+6y=144
3y=45
y= 45/3 =15
To find x
x+y = 24
x+15=24
x= 24-15
x= 9
fff
Therefore Peter worked 9 hours at job a and 15 hours at job b
