Answer:
90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World
Step-by-step explanation:
Since this is a problem of proportion we can use the Rule of three to solve this. We do this by multiplying the diagonal available values and dividing by the third value in order to get the missing variable, which in this case would be the number of stamps in the other country. Like so...
1.5 <=====> 135 stamps
1.2 <=====> x stamps (United States)
(1.2 * 135) / 1.5 = 108 stamps (United States)
1.5 <=====> 135 stamps
1 <=====> x stamps (Canada)
(1 * 135) / 1.5 = 90 stamps (Canada)
Finally, we can see that Katie had 90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World. All creating a ratio or 1:1.2:1.5

[tex]ln(x^9*y^8)[/tex]
Answer:
ln([tex]x^{9}[/tex] * [tex]y^{8}[/tex])
Step-by-step explanation:
property: ln( A * B ) = ln(A) + ln(B) :)
ln([tex]x^{9}[/tex]) + ln([tex]y^{8}[/tex])
property: ln([tex]A^{x}[/tex]) = xln(A)
9*ln(x) + 8*ln(y) ;)

which describes the combined variation in the formula h=V/pie r2
Answer:
The correct option is (c).
Step-by-step explanation:
The combined formula is given by :
[tex]h=\dfrac{V}{\pi r^2}[/tex] ...(1)
h is height
V is volume
r is radius
It is clear from formula (1) that h varies directly with V and inverse;y with the square of r.
Hence, the correct option is (c).
Answer:
h varies directly with V and inversely with the square of r.
Step-by-step explanation:
(Since pie is a constant, it's not said in the "sentence")

par cette inéquation :
5r + 9 > 10r - 126
Trouve l'ensemble-solution de cette inéquation.
Donne ta réponse en compréhension.
aider moi svp
Répondre:
r <27
Explication étape par étape:
Compte tenu de l'inégalité 5r + 9> 10r - 126
Nous devons trouver l'ensemble de solutions
5r + 9> 10r - 126
Ajouter 126 des deux côtés
5r + 9 + 126> 10r - 126 + 126
5r + 135> 10r
5r-10r> -135
-5r> -135
Divisez les deux côtés par -5 (notez que le signe changera)
-5r / -6 <-135 / -5
r <27
Par conséquent, les ensembles de solutions sont des valeurs inférieures à 27

5 - 2 (a + 3b) / 2 = ? / ?
Answer:
(5-2a+6b)/2
Step-by-step explanation:
According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2

The area of a square is always greater than its perimeter. Which of the following side-lengths for a square provides a counterexample that disproves the statement above?A. 2TT.B. 4.C. 7.5.D. 10.E. 125.
Answer:
a. 2
Step-by-step explanation:
Area of a square is calculated as:
[tex]Area = Length * Length[/tex]
And the perimeter is
[tex]Perimeter = 4 * Length[/tex]
For (a):
[tex]Length = 2[/tex]
[tex]Area = 2 * 2 = 4[/tex]
[tex]Perimeter = 4 * 2 = 8[/tex]
For(b):
[tex]Length = 4[/tex]
[tex]Area = 4 * 4 = 16[/tex]
[tex]Perimeter = 4 * 4 = 16[/tex]
For (c):
[tex]Length=7.5[/tex]
[tex]Area = 7.5 * 7.5-56.25[/tex]
[tex]Perimeter = 4 * 7.5 = 30,[/tex]
For (d):
[tex]Length = 10[/tex]
[tex]Area = 10 * 10 = 100[/tex]
[tex]Perimeter = 4 * 10 = 40[/tex]
For (e):
[tex]Length = 125[/tex]
[tex]Area = 125 * 125 =15625[/tex]
[tex]Perimeter = 4 * 125 = 500[/tex]
From (a) to (e), only side length 2 has a higher perimeter.
Hence, it disproves the statement

bigger cubical block. If each smaller block is 10 cm thick, find the thickness of the
bigger block.
Step-by-step explanation:
length of small block =10cm then volume=1000 there are 8 smaller block so volume =8× 1000=8000
so length of bigger block= cube root 8000...
a) are the triangle similar
b) solve for x

Driving 65 mph, it takes Alicia 2 hours to reach the airport to go on vacation. It then takers her 2 hours to get to her destination with a jet traveling at a speed of 350 mph. How many miles does Alicia travel to get to her destination? *
10 points
765 miles
830 miles
480 miles
415 miles
I’m giving 30 points
Answer:
830 miles
Step-by-step explanation:
By car, she travels 65 mph for 2 hours. 2 multiplied by 65 equals 130. She then travels 350 mph for 2 more hours by plane. 2 multiplied by 350 equals 700. Add the two distances together and you get 130 + 700 = 830

the next model of a sport car will cost 14.9% more than the current model. The current costs $43,000. how much will the price increase in dollars ? what will be the price of the next model
Answer:
The price of the new model will be $49,407.
Step-by-step explanation:
Percentages
The current model of a sports car costs $43,000. The new model is expected to cost 14.9% more than the current model.
The increase is:
14.9% of $43,000
=14.9/100 * $43,000
=$6,407
The cost of the new model is:
$43,000 + $6,407 = $49,407
The price of the new model will be $49,407.
(6-8)(9-10)-(4+2)(6+3) simplified in steps
Answer:
- 56
Step-by-step explanation:
First solve the parenthesis,
(6 - 8) = 2
(9 - 10) = -1
(4 + 2) = 6
(6 + 3) = 9
The equation now looks like; (2)(-1) - (6)(9).
Now solve the parenthesis again,
(2 x -1) - (6 x 9)
2 x -1 = -2
6 x 9 = 54
Now, complete the last equation,
-2 - 54 = -56
-56 is the answer!
Hope this helps!!!
______________________________
1.) Subtract all the parenthesis:[tex](6-8)=-2[/tex][tex](9-10)=-1[/tex]
- We do this because we have to get rid of the parenthesis.
Equation at the end of Step 1:
[tex]-2(-1)-(4+2)(6+3)[/tex]2.) Add all the parenthesis:[tex](4+2)=6[/tex][tex](6+3)=9[/tex]- We do this because we have to get rid of the parenthesis.
Equation at the end of Step 2:
[tex]-2(-1)-6[/tex] × [tex]9[/tex]3.) Now Multiply each side:[tex]-2(-1)=2[/tex][tex]6[/tex] × [tex]9=54[/tex]- We do this to get 1 number on each side left over, and the only way to do so is multiply the remaining numbers.
- Also, the reason we got 2 instead of -2 is because when multiplying 2 negatives by each other the quotient then turns out to be positive.
Equation at the end of Step 3:
[tex]2-54[/tex]4.) Subtract 54 from 2:[tex]2-54=-52[/tex]______________________________
