Original price: $340.00
markdown 50%.
Answer:
50/100(50%) x 340 = $170
If there is a 50% markdown, you would need to take 50%(1/2) away from the original price.
Answer:
$170
Step-by-step explanation:
Given the following question:
50% of 340
To find the answer we must first find 50% of 340 by using the formula to calculate percentages, and then subtract that answer from the original price to have our markdown.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{50\times340}{100}[/tex]
[tex]50\times340=17000[/tex]
[tex]17000\div100=170[/tex]
[tex]=170[/tex]
Now subtract from original price:
[tex]340[/tex]
[tex]340-170=170[/tex]
[tex]=170[/tex]
The new price after a 50% markdown is "$170."
Hope this helps.

6. The perimeter of a rectangle is 48 feet, and the length is 16 feet. What is the area?
Answer: 256 ft²
Step-by-step explanation:
The perimeter is calculated by:
P = 2l + 2w
so we know:
48 = 2(16) + 2w
48 - 32 = 2w
w = 16 feet
So the area is 16 x 16 = 256 ft²

Max rewrote the function f(x) = 4x² + 16x + 8 in vertex form by completing the square.
He concluded that the vertex is (-2, 4), which was incorrect. Consider Max's work, listed below.
In which step did Max make a mistake?
Step 1: f(x) = 4x² + 16x + 8
Step 2: f(x) = 4(x² + 4x) +8
Step 3: f(x) = 4(x² + 4x + 4) +8-4
Step 4: f(x) = 4(x + 2)² +4
The quadratic function f(x) = 4x² + 16x + 8 can be expressed in vertex form
Max's error is in step 3
How to determine the error in the function?The function is given as:
[tex]f(x) = 4x^2 + 16x + 8[/tex]
Factor out 4
[tex]f(x) = 4(x^2 + 4x) + 8[/tex]
Take the coefficient of x
[tex]k = 4[/tex]
Divide by 2
[tex]k/2 = 2[/tex]
Square both sides
[tex](k/2)^2 = 4[/tex]
Add and subtract 4 to the bracket
[tex]f(x) = 4(x^2 + 4x + 4 - 4) + 8[/tex]
Expand
[tex]f(x) = 4(x^2 + 4x + 4) + 8 - 16[/tex]
By comparing the above equation to step 3 of Max solution, we can determine that Max's error is in step 3

Select the correct answer. What is the simplified form of 377-577? O A – 287 O B. 287 Oc. -√14 OD. 157
Answer:
- 200
Step-by-step explanation:
377 is lesser than 577.
Here,
577 is the Greater number.
377 is the Smaller number.
When Smaller number is subtracted from Greater number, the result will be ( - ).
So,
377 - 577 = - 200

Answer:

Step-by-step explanation:
We have the equation:
[tex]34\cdot 3^{x-2}-2\cdot 3^{x-3}=0.8\cdot 10^{x-2}+10^{x-3}[/tex]
Let's simplify this a bit. Let [tex]u=x-2[/tex]. Then [tex]u-1=x-3[/tex]. We can substitute the exponents:
[tex]34\cdot3^u-2\cdot 3^{u-1}=0.8\cdot 10^u+10^{u-1}[/tex]
Use the properties of exponents, we can write [tex]3^{u-1}=\frac{3^u}{3}[/tex]. We can do the same thing on the right. So:
[tex]34\cdot3^u-2\cdot \frac{3^u}{3}=0.8\cdot 10^u+\frac{10^u}{10}[/tex]
We can now factor out a [tex]3^u[/tex] from the left and a [tex]10^u[/tex] on the right. This yields:
[tex]3^u(34-2\cdot\frac{1}{3})=10^u(0.8+ \frac{1}{10})[/tex]
Evaluate the expressions within the parentheses:
[tex]3^u(34-\frac{2}{3})=10^u(\frac{9}{10})[/tex]
Evaluate:
[tex]3^u(\frac{100}{3})=10^u(\frac{9}{10})[/tex]
Now, let's multiply both sides by [tex]\frac{3}{100}[/tex]. So:
[tex]3^u=10^u(\frac{9}{10})(\frac{3}{100})[/tex]
Also, let's divide both sides by [tex]10^u[/tex]. Multiply on the right:
[tex]\frac{3^u}{10^u}=\frac{27}{1000}[/tex]
Therefore:
[tex]3^u=27\text{ and } 10^u=1000[/tex]
We can now substitute back u. Notice that 27 is the same as 3 cubed and 1000 is the same as 10 cubed. So:
[tex]3^{x-2}=3^3\text{ and } 10^{x-2}=10^3[/tex]
Since they have the same base, their exponents must be equal. Therefore:
[tex]x-2=3[/tex]
Add 2 to both sides:
[tex]x=5[/tex]
So, the value of x is 5.

A marathon is approximately 26.2 miles. Your friend says that if you
continue to run at this speed, you will not be able to complete a marathon
in less than 4 hours. Is your friend correct? Explain.
Answer:
yes because it would take about 6 hours and 55 minutes.
Step-by-step explanation:
26.2 × 4=6.55
Answer 6.55 or 6 hours and 55 minutes
The speed of Your friend will be 6.55 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
A marathon is approximately 26.2 miles. Your friend says that if you continue to run at this speed, you will not be able to complete a marathon in less than 4 hours.
The speed of Your friend will be
S = 26.2 / 4
S = 6.55 miles per hour
The speed of Your friend will be 6.55 miles per hour.

Tormod bought a perfectly square table but found out it won't fit through his study
door. To solve the problem, he reduces its width by 9cm but also extends its length by
9cm. Its new area is 309cm?
What was the area of his original square table?
Answer:
390 cm^2
Step-by-step explanation:
Let's call the dimensions of the original square x by x. Its area is x^2.
After the table is altered, its dimensions are x + 9 by x - 9, and you're given the area is 309 cm^2.
[tex](x+9)(x-9)=309\\\\x^2-81=309\\\\x^2=390[/tex]
This last equation is telling us the area of the original, square table.

At Thomas High School, 200 students go to school by their own vehicle. If this number of students is 40% of school enrollment, then how many students are there in the school altogether?
Answer:
500 students
Step-by-step explanation:
40% = 200 students
divide both by 4 to 10%
10% = 50
multiply both by 10 to get 100%
100% = 500
or the quicker way,
200 x 2 = 400 (80%) + 100 (20%) = 500 (100%)

Answer:
$1322.67
Step-by-step explanation:
Let the total amount that Sarah deposited be $x
using the annuity formula:
A=P[((1+r)^n-1)/r]
A=future value
r=rate
n=number of years
from the information given:
A=$500000
r=2.75%
n=65-42=23 years
p=$x
thus plugging our values in the formula we get:
500000=x[((1+0.0275)^(23)-1)/(0.0275)]
500000=31.50x
x=15,872.04883
She deposited 15,873.04883 per year
The monthly deposit will therefore be:
15873.04883/12=$1322.67

While shopping, Kyla found a dress that she would like to purchase, but it costs $49.50 more than she has. Kyla charges $5.50 an hour for babysitting. She wants to figure out how many hours she must babysit to earn $49.50 to buy the dress.
Answer:
9 hours
Step-by-step explanation:
We can do this 2 ways but I think you will want this the easiest way :)
So we can divide:
49.50/5.50
9
Or we can multiply and keep multiplying 5.50 by different numbers until we get 49.50 or over (this way will take longer)
5.50 x 1
5.50 x 2
and so on and so fourth
With the first way we figued out she will need to babysit for 9 hours :)
