When Jaylen started high school, 1,430 students attended his school. On the day of his graduation, only 1,001 students attended his school.
The number of students who attended Jaylen's school decreased by what percent?
Answer:
The number of students decreased by 30%.
Step-by-step explanation:
Subtract 1430 from 1001, then find the absolute value.
[tex]\frac{|1001-1430|}{1430}\\\frac{|-429|}{1430}\\\frac{429}{1430}[/tex]
Simplify 429/1430 by cancelling out 143.
[tex]\frac{429/143}{1430/143}\\\frac{3}{10}[/tex]
Convert 3/10 into a percentage by multiplying it by 100.
[tex]\frac{3*100}{10}\\\frac{300}{10}\\30[/tex]
The decrease of students was 30%.

The Large Hadron Collider at a research lab is contained in a circular tunnel with a circumference of 26.7 km. What is the radius in kilometers of the circular tunnel in terms of π?
Enter the correct answer in the box.
[ ]km
Answer:
4.2494369805536 km
Step-by-step explanation:
r = 4.2494369805536km because 26.7/2π which means:
26.7 ÷ 3.14159265359 x 2 = 4.2494369805536 km.
Answer:
13.35/π km or 26.7/2π km
Step-by-step explanation:
"In terms of π" means leave pi in the answer. No need to use a decimal equivalent.
The radius is half of the circumference divided by π.

Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answer: [tex]13x+26 \ge 65[/tex]
If you solve for x, you get [tex]x \ge 3[/tex] which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as [tex]13x+26 \ge 65[/tex] which sets up the inequality.
----------------------------
Let's solve for x
[tex]13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\[/tex]
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).
Answer:
Step-by-step explanation:
65= 26+13x

Write and solve an equation that can be used to find the value of x then find the perimeter of each shape
Answer:
Equation: (2x+5)4=(2x+8)3
X: 2
Perimeter: 36
Step-by-step explanation:
You would multiply 2x+5 and 4 because there are four sides to a square, so the perimeter of the square would be 8x+20. This would go same for the triangle, making the perimeter 6x+24.
So 8x+20=6x+24 is your new equation. Then, you do the opposite of the order of operations, and add or subtract first. It would be easiest to subtract 20 and 6x from both sides.
That leaves you with 2x=4. Dividing 2 by both sides means x=2
You can plug this in to prove if it is correct.
16+20=36
12+24=36
