Alyson opened a savings account with
$100. She saves $50 per month. Which
equation shows how many months, m,
Alyson will have to save to have a total of
$250 in her account?
Answer:
100 + 50m = 250
50m = 250 - 100
50m/50 = 150/50
m = 3
Alyson will have to save for 3 months to have a total of $250.
Ken bought 2 video games and 1 DVD for a total of $105. Jerome bought 1 video game and 4 DVDs for a total of $80. Which system of equations can be
used to find the cost, in dollars, of each video game (v) and each DVD (d) at the store?
Answer:
I think that the Linear system of equations can be used to find the cost.
Step-by-step explanation:
Answer:
2v + 1d = 105
and
1v + 4d = 80
Step-by-step explanation:
ken : 2v + 1d = 105
Jerome : 1v + 4d = 80
1v + 4d = 80 Try to get a video games by its self
- 4d -4d
1v = 80 - 4d
Plug into kens equation..
2(80 -4d) + 1d = 105
160 - 8d + 1d = 105
-160 -160
-7d = -55
/-7 /-7
d = 7.86 (rounded)
Plug into Jeromes equation
1(7.86) + 4v = 80
- 7.86 - 7.86
4v = 72.14
/4 /4
v = 18.035 (round = 18)

Answer:
The area is 2,600 cm^2
Step-by-step explanation:
The area of a rectangle is the product of its sides
And the difference between both areas is 1,400 cm^2 (P-Q)
Thus, we have it that;
40(3x-10) - (30(x + 15)) = 1,400
120x - 400 - 30x - 450 = 1400
120x -30x -400-450 = 1400
90x - 850 = 1400
90x = 1400 + 850
90x = 2,250
x = 2,250/90
x = 25
The area for painting P
is;
40 (3x - 10)
Substituting the value 25 for x
we have
40 ( 3(25) -10)
= 40(75-10)
40 * 65 = 2,600 cm^2

Sita bought a sofa set for Rs 30,000 and a dining set for Rs 20,000. He sold the sofa set at a loss of 5% but made a profit of 5% on the dining set. The net result of the transaction is?
Answer: See explanation
Step-by-step explanation:
Sita bought a sofa set for Rs 30,000 and sold the sofa set at a loss of 5%. The loss on the sofa will be:
= 5% × 30000
= 5/100 × 30000
= 0.05 × 30000
= 1500
Selling price of the sofa = 30000 - 1500 = 28500
Sita bought a dining set for Rs 20,000 and made a profit of 5% on the dining set. The selling price of the dining set will be:
= 20000 + (5% × 20000)
= 20000 + (0.05 × 20000)
= 20000 + 1000
= 21000
The cost price of the sofa and dining set will be:
= Rs 20000 + Rs 30000
= Rs 50000
The selling price of the dining set will be:
= Rs 28500 + Rs 21000
= Rs 49500
The net result of the transaction is will be:
Selling price - Cost price
= 49500 - 50000
= -500
There's a net loss of $500

Melanie is going to invest in an account paying an interest rate of 5.2% compounded
monthly. How much would Melanie need to invest, to the nearest hundred dollars,
for the value of the account to reach $19,600 in 19 years?
Answer:
7300
Step-by-step explanation:
I got it right
Melanie would need to invest an amount of $7300.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
The final amount in a compound interest can be calculated using the formula,
A = P (1 + [tex]\frac{r}{n}[/tex] )^(n t)
Here A is the final amount, P is the principal value, r is the rate of interest, n is the number of times interest is compounded per year and t is the number of years.
Given,
A = $19,600
r = 5.2% = 5.2/100 = 0.052
Since it is compounded monthly, n = 12
t = 19 years
Substituting,
19,600 = P (1 + [tex]\frac{0.052}{12}[/tex])^ (12 × 19)
19,600 = P (1.0043)^(228)
19,600 = P (2.68)
P = 19,600 / 2.68
P = 7313.0767 ≈ 7300 to the nearest hundred
Hence the value of the account will reach $19,600 n 19 years if she invest an amount of $7300.

Calculate the volume of liquid that would fill the bowl of the glass. Show all your work.
Answer:
52.36
Step-by-step explanation:
Formula to find volume in a cone is
V = pi • radius^2 h/3
So we fill in the numbers
V = pi •
the radius is half of diameter,
The diameter is 5
So it's
V = pi • 2.5
since it's half of 5
V = pi • 2.5^2 h/3
the height is 8 so we fill it in
V = pi • 2.5^2 8/3
When calculated, you get..
52.36
The volume of the liquid which can fill the bowl of the glass (in shape of cone) with the liquid is 49.74 cm³.
What is of volume of solid?Volume of solid is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
The volume of the cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2\sqrt{l^2-r^2}[/tex]
Here, (r) is the radius of the base of the cone and (l) is the slant height of the cone.
Here, the diameter of the cone is 5 cm. thus the radius of the cone is,
[tex]r=\dfrac{5}{2}\\r=2.5\rm cm[/tex]
The slant height of the cone is 8 cm. Thus, put the value to find the volume of cone as,
[tex]V=\dfrac{1}{3}\pi (2.5)^2\sqrt{(8)^2-(2.5)^2}\\V\cong 49.74\rm cm^3[/tex]
Thus the volume of the liquid which can fill the bowl of the glass (in shape of cone) with the liquid is 49.74 cm³.
