Answer:
7.5
Step-by-step explanation:
Because Noah has five dollars, 100% of 5 is 5, and 50% of 5 is 2.5 so Diego has 7.5 dollars.

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
A quantity with an initial value of 7800 decays exponentially at a rate of 2% every 3
years. What is the value of the quantity after 4.7 decades, to the nearest hundredth?
Answer:
5683.77
Step-by-step explanation:
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

18 red buttons: 12 blue buttons
18/12
Divide the top and bottom by 6
18/6 = 3
12/6 = 2
3/2
Answer:
3/2
Step-by-step explanation:
18/12 can be broke down and easily simplified given the numbers are even.
18 divided by 2 = 9
12 divided by 2 = 6
9/6
18 divided by 3 = 6
12 divided by 3 = 4
6/4
Simplest form;
18 divided by 6 = 3
12 divided by 6 = 2
3/2

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

Find the interest due on $1,090 at 8% for 5 years.
Answer:
$1601.57, $511,57 more intrest
Step-by-step explanation:
1,090*1.08^5
= 1601.5676
Round up to get 1601.57
Interest = Principal × rate × time/100
=> 1090×8×5
= 43,600/100
=> $436

(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]______________________________

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:

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
b) 8 metallic cubical blocks of equal size are melted and joined together to form a
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...

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.
