Answer:
x = 9
Step-by-step explanation:
Assuming the rectangles are similar
13 x
------ = ---------
130 90
Using cross products
13*90 = 130*x
Divide each side by 130
13*90/130 = x
x = 9
Answer:
x/90 = 13/130(you can simplify this btw)
x90 x90
X = 9
Make both of them ratios
X to 90 and pick another random one 13 to 130.
Make sure to make them equal to eachother then just solve for x.
You can also compare it to 9 to 90
It would still work:
x/90 = 9/90
x90 x90
X = 9, x would also equal 9

Lucy knows about 6 Web sites that sell a designer T-shirt she loves. The mean price of the T-shirt is $14 and the range of price is $7. What are possible prices for the T-shirt?
Answers
Answer:
D
Step-by-step explanation:
Given that :
Mean = 14
Range = 7
Evaluating the options given :
A. $14, $14, $14, $14, $7, $7
For option A :
Mean = (14 + 14 + 14 + 14 + 7 + 7) = 70 / 6 = 11.66 (incorrect)
B. $14, $14, $14, $14, $14, $21
Mean = (14 + 14 + 14 + 14 + 14 + 21) = 91 / 6 = 15.17 (Incorrect)
C. $13, $13, $13, $15, $15, $15
Range = 15 - 13 = 2 ( Incorrect)
D. $13, $12, $15, $15, $11, $18
Range = (18 - 11) = 7
Mean = (13+12+(15*2)+11+18) / 6 = 84/6 = 14
Option D is Correct
The profit from a business is described by the function P(x) = -x^2 + 10x - 4, where x is the number of items made, in thousands, and P(x) is the
profit in dollars. How many items will maximize the profit?
A 5,000
B. 10,000
C. 20,000
D. 50,000
Answers
Therefore, 5000 items can maximize the profit
The correct answer is an option (a)
What is Profit ?The money that you make when you sell something for more than it cost you.
For given example,
profit is described by the equation :
[tex]P (x) = -x^2 + 10x -4[/tex]
We need to maximize the profit P(x)
[tex]\Rightarrow \frac{d}{dx}P(x)=0\\\\\Rightarrow \frac{d}{dx}( -x^2 + 10x -4 ) =0\\\\\Rightarrow -2x+10=0\\\\\Rightarrow -2x=-10\\\\\Rightarrow x=5[/tex]
since , x is the number of items made in thousand
Therefore, 5000 items can maximize the profit
The correct answer is an option (a)

Two runners are participating on a 720-metre circular track. They run in opposite directions, each at a constant speed. The first runner needs four minutes to complete the full loop and the second runner needs five minutes. How many metres does the second runner travel between two consecutive meetings of the two runners?
Answers
Happy Pride Month!
Answer:
320m
Step-by-step explanation:
let the two runners be A and B
with Va and Vb as their velocities
velocity=distance/time
Va=720/4*60
=3m/s
Vb=720/5*60
=2.4m/s
Let the 2 runners start from a common position X and meet at Y
so the 2 consecutive meetings happen at X and Y
so we have to find time of meeting at Y as we know that of X (which is t=0)
720=Va*t+Vb*t
t(5.4)=720
t=133.33 or t=720/5.4
therefore distance travelled by B =Vb*t
=2.4*720/5.4
=319.99m
=320m

=) Asif deposits $650 into a bank paying a simple interest. He leaves the money there
for 5 years. At the end of the 5 years, the amount in the bank is $763.75.
Calculate the percentage rate of interest the bank paid per year.
Answers
Answer:
interest he got per year is 22.75
Step-by-step explanation:
deposited money = 650
after 5 years = 763.75
interest he got = 763.75 - 650
= 113.75
interest he got each year = 113.75 / 5
= 22.75

⭐ Initially, we have to find the reason why it was -1.5:

➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.
[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]
⌛ So, we will have to find what x is worth in this case:
[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]
[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]
→ Knowing this...
[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]

Is b = 4 a solution to the inequality below?
3 ≥ b
Also can someone tell me how to do this? step by step?
Answers
Answer:
b=4
Step-by-step explanation:
4 Also can someone tell me how to do this? step by step?
What they’re saying is substitute the number 4 into the inequality wherever the letter b appears.
So they are asking if “3 is greater than or equal to 4” is true or not true.
If it was true, then b = 4 is a solution to the inequality. Since it is false, it is not a solution to the inequality. Does that make sense?

The price with coupon B is $ less than the price with coupon A.
$
Answers
Answer: Coupon B gives the lower price
The price of coupon B is 3.75 dollars less than the price of coupon A.
======================================================
Explanation:
15% off means she saves 15% of the original price.
15% of 95 = 0.15*95 = 14.25
Rachel saves $14.25 if she goes with coupon A.
We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).
If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars
Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.
