An electronics company finds that 5 out of 1,535 capacitors produced are damaged. How many damaged items can they expect if the company produces 23,025 capacitors?
Answer:
the damaged items expected in the case when the 23,025 capacitors produced is 75
Step-by-step explanation:
The computation of the damaged items expected in the case when the 23,025 capacitors produced is shown below:
= (5 × 23,025 capacitors) ÷ (1,535 capacitors)
= 75
Hence, the damaged items expected in the case when the 23,025 capacitors produced is 75

What is the area, in square feet, of the shape below? Express your answer as a fraction in simplest form.
The area of the triangle will be 5/8 square feet.
What is triangle?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted ΔABC.
In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Area: ½ × base × heightPerimeter: sum of side lengths of the triangleNumber of vertices: 3Number of edges: 3Internal angle: 60° (for equilateral)Sum of interior angles: 180°Right angle: 90 degreesGiven is a triangle as shown in the image.
Now, the area of triangle will can be written as -
[A] = 1/2 x [b] x [h]
[A] = 1/2 x 5/3 x 3/4
[A] = 1/2 x 5/4
[A] = 5/8 square feet
Therefore, the area of the triangle will be 5/8 square feet.

Which of the following shows the solution and graph to the inequality
2x + 1 ≤ 15?
Answer:
C or D
Step-by-step explanation:
I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.
Option D shows the solid dot along with [tex]x\leq 7[/tex] so our answer is
Option D.
The given inequality is 2x + 1 [tex]\leq[/tex] 15.
We have to see which of the given option shows the solution and graph to this inequality.
What are a solid dot and an open dot?A solid dot indicated on a number line graph shows that the given number is also a possible solution, whereas an open dot indicates that the given number cannot be a solution.
We see that in the given inequality, 2x + 1 must be less than or equal to 15.
And the maximum value we can take is 7 because,
2(7) + 1
14 + 1
15
So we can take 7 and any values less than 7 i.e [tex]x\leq 7[/tex] to satisfy the inequality 2x + 1 [tex]\leq[/tex] 15.
We see that Option D gives us [tex]x\leq 7[/tex] along with the solid dot.
Hence Option D is our answer.

Find the value of x if 7,21,x and 35 are in proportion
graph this please it’s been due
Answer:
Step-by-step explanation:
Here, we want to graph the given line
To do this, we need the x and y intercept
The general equation form
is ;
y = mx + b
where m is slope and b is the y-intercept
from the question, b is -2
The point at b is (0,-2)
To get the x-intercept, equate y to 0
0 = 3x - 2
3x = 2
x = 2/3
So the x-intercept is (2/3,0)
So to graph the line, we have to join the points;
(0,-2) and (2/3,0) with a straight line

Find the measure of angle 1.
9514 1404 393
Answer:
(a) 84°
Step-by-step explanation:
If the upper side of angle 1 is extended so that it crosses the lower parallel, the angle it makes there corresponds to the one marked 51°, so is also 51°. That makes angle 1 the exterior angle of a triangle with remote interior angles of 51° and 33°. Angle 1 is the sum of those angles:
∠1 = 51° +33° = 84°
_____
Alternate solution
Draw a line through the vertex of angle 1 parallel to the other two parallel lines. The lower half of angle 1 is then an alternate interior angle to the one marked 33°, so is 33°. The upper half of angle 1 is a corresponding angle to the one marked 51°, so is 51°. That makes angle 1 be the sum of 33° and 51° angles, so 84°.

A total of 937 people attended the play.
Admission was $2.00 for adults and $0.75
for students. The total ticket sales
amounted to $1,109. How many students
and adults attended the school play?
First complete the equations below, where A
stands for Adults and S stands for Students.
2A + 0.75S = 1,109; A + S = 937
Now use the equations to find the number of
students and adults.
Students = [?]; Adults = []
Answer:
612 students and 325 adults
Step-by-step explanation:
I'll use substitution for this set of equations. I'll start with 2a + 0.75s = 1,109.
2a + 0.75s = 1,109
Subtract 0.75s from both sides.
2a = -0.75s + 1109
Divide both sides by 2.
a = 1/2(-3/4s + 1109)
Make 1/2(-3/4s + 1109) into a single fraction
a = -3/8s + 1109/2
Substitute -3/8s + 1109/2 for a in the other equation (a + s = 937).
-3/8s + 1109/2 + s = 937
Add -3/8s to s.
5/8s + 1109/2 = 937
Subtract 1109/2 from both sides.
5/8s = 765/2
Multiply both sides by 8/5, the reciprocal of 5/8.
s = 612
Now head back to the original equation, and substitute s for 612.
a = -3/8 * 612 + 1109/2
Multiply -3/8 by 612.
a = (-459 + 1109)/2
Add 1109 to -459 and divide by 2.
a = 650/2
a = 325
The system is solved. There are 612 students and 325 adults.

4/_ ‘ _/36
Which number goes into both boxes?
A) 6
B)9
C)12
D)18
Answer:
C) 12
Step-by-step explanation:
What you are trying to find is when 4/_ = _/36. The only number that will set these two ratios equal is 12. This is because 4/12 simplifies to 1/3, and 12/36 simplifies 1/3, meaning the two ratios are equivalent.

A box contains 5 chocolate chip cookies, 4 sugar and 6 oatmeal raisin. What is the probability of picking a chocolate chip cookie?
plssss helpppp
Answer:
5/10
Step-by-step explanation:
if you add all the non- chocolate chip cookies than you have 10 other cookies.
since there are 5 chocolate chip cookies than the probability would be
5/10 or 1/2
The probability of picking a chocolate chip cookie is 1/3.
Given that, a box contains 5 chocolate chip cookies, 4 sugar and 6 oatmeal raisin.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here,
Total number of outcomes =15
Number of favorable outcomes = 5
Probability of an event = 5/15
= 1/3
Therefore, the probability of picking a chocolate chip cookie is 1/3.

What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To complete the square for the function.
A(x) = -2x² + 36x,
We need to first factor out the coefficient of x², which is -2:
So,
A(x) = -2(x² - 18x)
Next,
We need to add and subtract a term that will allow us to factor the expression inside the parentheses into a perfect square.
To do this,
We need to take half of the coefficient of x, which is -18/2 = -9, square it, and then add and subtract the result.
So,
A(x) = -2(x² - 18x + 81 - 81)
Now,
We can rewrite the expression inside the parentheses as a perfect square.
A(x) = -2((x - 9)² - 81)
Finally, we can distribute the -2 and simplify.
A(x) = -2(x - 9)² + 162
So,
The missing value is 162,
Thus,
The missing value is 162,
