Grayson is 49.65 inches tall. Grayson's younger brother Zeke is 4.3 inches shorter than Grayson. How tall is Zeke?
Answer:
Zeke is 45.35 inches tall
Step-by-step explanation:
To find out how tall Zeke is, you must subtract 4.3 from 49.65 (Shorter means less - so subtraction)
49.65 - 4.3 = 45.35 inches tall
Answer:
45.35

A $65 coat is on sale for 15% off,
what is the cost of the coat
after the sale?
Answer:
$55.25
Step-by-step explanation:
15% of $65: [tex]\frac{65}{1}[/tex] × [tex]\frac{15}{100} = \frac{975}{100}[/tex] $975/100 = $9.75$65 - $9.75 = $55.25I hope this helps!
$55.25 is the cost of the coat after the sale.
Step-by-step explanation:
Given:
Price of the coat = $65
Percentage of discount = 15%
To find:
The cost price of coat after the sale
Solution:
Cost price of coat = $65
Percentage of discount = 15%
The amount of discount will be 15% of the price of the coat.
Amount of discount :
[tex]=\frac{15}{100}\times \$65 \\=\$9.75[/tex]
The cost price of the coat:
[tex]=\$65-\$9.75=\$ 55.25[/tex]
$55.25 is the cost of the coat after the sale.

physics convention 11 companies set up equal sized square booths in a row along one wall of a convention center.The booths are adjacent to each other and a 2-ft wide walkway surrounds the block of booths on three sides. The total area of the booths and walkway is 1200 ft^2. What is the side length of each booth?
Answer:
Side length of each booth is 8.35 ft approximately.
Step-by-step explanation:
There are 11 companies set up equal sized square booths in a row along one wall of a convention center.
Now, refer the diagram to answer the problem.
It is given area is 1200.
So, length x width =1200
(11x+24)(x+2)=1200
Multiply using FOIL method.
[tex]11x^{2}[/tex]+22x+24x+48=1200
[tex]11x^{2}[/tex]+46x+48-1200=0
[tex]11x^{2}[/tex]+46x-1152=0
Solve using quadratic formula
x=[tex]\frac{-46+/- \sqrt{46^{2}-4(11)(-1152 } }{2(11)}[/tex]
x=[tex]\frac{-46+/-\sqrt{2116+50688} }{22}[/tex]
x=[tex]\frac{-46+/-\sqrt{52804} }{22}[/tex]
Simplify it
[tex]x=\frac{-49+/- 229.79}{22}[/tex]
Simplify to get two values for x.
x=8.35; x=-12.67
Here negative does not work.
Side length of each booth is 8.35 ft.
Kareem earns y dollars per month at his accounting job. Express his annual salary using
the K abbreviation found in classified ads.
Answer:
0.012yK
Step-by-step explanation:
[tex]\frac{y*12}{1000} K[/tex] > K=1,000
12 divided by 1000 is 0.012.
The required annual salary for Kareem is 0.012yK.
Given that,
Kareem earns y dollar per month at his accounting job. Express his annual salary using the K abbreviation found in classified ads is to be determined.
The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
$1 K = $1000 (for a year)
Since salary for a month is y
Salary for a year = 12 * y
Transforming it into K abbreviation
Multiplied and divide by 1000 on the right side
Annual salary = 12 y 1000 /1000
= 12/1000 * y K
= 0.012yK
Thus, the required annual salary for Kareem is 0.012yK.

the length of each side of this regular pentagon is 37 mm. what is the perimeter
Answer:
185mm
Step-by-step explanation:
37 times 5 is 185
Answer:
185 mm
Step-by-step explanation:
There are 5 sides in a pentagon. Each side is 37 mm. Add 37 5 times or multiply 37 by 5.
37mm + 37mm + 37mm + 37mm + 37mm
or
37mm × 5

x = 2
x = -1/3
Step-by-step explanation:
Hi there!
You'll notice that this equation is a quadratic. When graphed, this equation looks like a parabola that crosses the x-axis at two points, which can be written as ordered pairs with an x value and a y value.
We know that both of these points will have a y value of 0, but we don't know what the x values of the points are—these are what we want to find.
(Check out the graphing program Desmos—type in your equation and it will graph it out for you.)
Notice that your equation follows this structure:
[tex]ax^2+bx+c=0[/tex]
In our case,
[tex]a=3\\b=-5\\c=-2[/tex]
We can plug our values of a, b, and c into the quadratic equation to find the two x values.
I've attached a picture of my work. At the top is the quadratic equation. I substituted our values in and solved.
You'll notice that the answer I ended up with has a ± symbol. We have to simplify this down two different ways to get our two answers: once using the plus sign, once using the minus sign. This will give us two different values for x.
We'll start with the plus sign:
[tex]\frac{5+7}{6} \\=2[/tex]
So: one of our x values is 2.
Now the minus:
[tex]\frac{5-7}{6} \\=-\frac{1}{3}[/tex]
Our other x value is -1/3.
You can check to make sure these answers work by plugging them back into the original equation for x. If they work, the left side of the equation should boil down to 0.
Let me know if you have any other questions! Best of luck with getting caught up in Algebra!

I need HELLLPPPPP. A student bought concert tickets online. The total cost, c, in dollars, of t tickets can be
found using the function below.
c(t) = 87.50t + 12.50
If the student spent a total of $800 on tickets, how many tickets did she buy?
+/-
Answer:
The answer is 9.
Step-by-step explanation: Things to know: c is total cost and t tickets. 800 is the total cost so plug it in to c. You want to get t (tickets) alone.
original: c(t)=87.50t+12.50
Now with the 800: 800=87.50t+12.50
Subtract 12.50 to both sides: 787.5=87.50t
Divide 87.50 to both sides: 9=t
