Answer:
Cds sold= 290
Step-by-step explanation:
Giving the following information:
A shop sold 250 CDs last week. The sales of CDs increased by 16% this week.
To calculate the number of CDs sold this week, we need to use the following formula:
Cds sold= Cds sold last week*(1 + percentage increase)
Cds sold= 250*1.16
Cds sold= 290

y=−4x−3
y=−2x+1
x=x=x, equals
y=y=y, equals
Answer:
x = -2, y = 5.
Step-by-step explanation:
y=−4x−3
y=−2x+1
Because y is common to both left sides:
-4x - 3 = -2x + 1
-4x + 2x = 1 + 3
-2x = 4
x = 4/-2
x = -2.
So y = -4(-2) - 3
= 8 - 3
= 5 .

HELP ME PLZZZZ!!!! ASAP
Answer: [tex]2\sqrt{22}[/tex]
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2} +b^{2} = c^{2}[/tex], where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.
[tex]9^{2} +b^{2} = 13^{2}[/tex]
[tex]81 +b^{2} = 169[/tex]
Since we don't know what [tex]b^{2}[/tex] is, we're going to isolate it by subtracting 81 on both sides
[tex]b^{2} = 88[/tex]
We have to square root both sides in order to find out b (or x in the problem).
[tex]\sqrt{b^{2}} = \sqrt{88}[/tex]
When you put this on a calculator it would result in [tex]2\sqrt{22}[/tex] which is the answer d in the problem.

Making x equal to 4
Answer:
x= -3
Step-by-step explanation:
Rewrite the equation 7+2x/3=5
Now subtract 7 from both sides to isolate x.
2x/3= -2
Now to isolate 2x, multiply each side by 3
2x=-6
x=-3
Check 7+2(-3)/3=5
7-6/3=5
7-2=5
So this is correct

Answer:
The 2nd option:
1.339×10⁶
Step-by-step explanation:
To find the combined capacity, add the two values together so:
(8.12×10⁵ ) + ( 5.27 × 10⁵ )
It will be simpler to add if you change it out of its
standard form
812000+527000
= 1339000
Now you can write in back in standard form, which will be

The first two terms of a sequence are a1 =4 and a2= -2. Let a3 be the third term when the sequence is arithmetic and let b3 be the third term when the sequence is geometric. Find a3+b3
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7

What is simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
We have,
Principal = P = $8,000
Rate = R = 2.5%
Amount = A
Time = 4 years
Simple Interest:
= (P x R x T) / 100
= (8000 x 2.5 x 4 ) / 100
= 800
Amount = Simple interest + Principal
A = 800 + 8000
A = 8800
Thus,
The total value of the account after 4 years is $8800.
