Freddy’s savings account went from $520 to $321 after he purchased a new bike. What was the percent decrease?

Answer:

B.31

Step-by-step explanation:

That's the answer.

Answer:

x = 31

Step-by-step explanation:

By Linear Pair

3x + 31 + 2x - 6 = 180

5x + 25 = 180

5x = 155

x = 31 Answer

Answer:

7.35 Million

Step-by-step explanation:

So you already have the function and all you have to do is find the years.

p(t)=3.98(1.02)^t

I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.

p(t)=3.98(1.02)^31

From here you would jut plug this function into your calculator and get a final answer of:

7.35 Million

Hope this helped :)

Answer:

3)      (N)  angle Q = 90 degrees

4)      (E)  angle 1 = 88 degrees

5)      (G)  angle 3 = 110 degrees

Step-by-step explanation:

3) angle Q = 1/2(270-90) = 90

4) central angles equal arc angles

5) angle supplemental to angle 3 is 1/2(140), so angle 3 = 180-70 = 110

Answer:

10 miles per hour

Step-by-step explanation:

20 divided by 2 = 10

Answer:

To solve this you must first know how Log works.

When we say log1000 of base 10

Or

log1000=3

What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).

So log2x=−5 (i am assuming base 10 since it is simple algebra) means that

2x=10−5

x=10−5/2

Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.

The question is not written properly, so I will give the answer(s) I think would be suitable.

If you were trying to solve this

log2x=−5

⟹x=2−5

⟹x=132

But if you were trying to solve this

log2x=−5

⟹log102x=−5

⟹2x=10−5

⟹x=12×105=1200000

Answer:

43

Step-by-step explanation:

you plug in the values

3m^2 + 2p^2 - 15

= 3(3)^2+2(10)^2-15

= 3×9+2×100-15

= 27+200-15

= 227-15

= 212

Just subtitute the value of m and p to the equation

Hope it help u :)

Answer:

y = -15x + 35

Step-by-step explanation:

3x + 1/5y = 7

1/5y = -3x + 7

y = 5( -3x + 7)

y = -15x + 35

Answer:

1.414

Step-by-step explanation:

Answer:

x = 6√3

Step-by-step explanation:

Let's just look at the right triangle. This is a 30° 60° 90° triangle. The value of the large leg (x) will be the value of the small leg times √3. The value of the hypotenuse (12) is the value of the small leg times 2. Since we know that, we can divide 12 by 2 to find out the value of the small leg will be 6. Finally, know that we know that 6 is the value of the small leg, we can multiply 6 by √3 to find that the value of x = 6√3.

Answer: [tex]6\sqrt{3}[/tex]

Step-by-step explanation:

This is a 30-60-90 triangle because we know that there is a right angle and a 60 degree angle

the side opposite to 30 degrees is a, 90 degrees is 2a, and the side opposite to 30 degrees is [tex]a\sqrt{3}[/tex]

2a = 12 so a = 6 and  [tex]a\sqrt{3}[/tex] is [tex]6\sqrt{3}[/tex]

I'm going to assume that y is the length of the red line.

Answer:

p - p(.60)

Step-by-step explanation:

to find 60% of p you turn 60% into a decimal, which is .60, next you multiply .60 by p which will give you 60% off of p,

finally you take the total which is p and subtract off the discount which is .60p, thus p-p(.60)

also... another way to solve this is that if you are getting 60% off that means you are paying 40% of the price, thus you could just multiply p(.40) to get the amount the person would actually pay

Answer:

100/500 = 0.2

common ratio is 0.2

Answer:

I think it is correct and is 1 and 2

Step-by-step explanation:

5×4^(x+1)-16^x=64

0=64+16^x-5×4¹×4^x

0=(4^x)²-2×4^x×10+10²-10²+64

0=(4^x-10)²-36

(4^x-10)²=36

4^x-10=√36

4^x=+-6+10

when positive

4^x=4²

:.x=2

when negative

4^x=4

:.x=1

:.x=1,2 answer.

Answer:

110

Step-by-step explanation:

They are equal to each other.

23x-5= 21x +5

2x = 10

x = 5

21(5) +5 = 110°

23(5) -5 = 110°

So it works. Angles are 110°

Answer:

Question 1: 12x

Question 2: 16x

Question 3: 12x+8y

Step-by-step explanation:

Answer:

1. A. 12 x

2.A. 16x

3. B. 12+8y

Answer:

see explanation

Step-by-step explanation:

let n and n + 2 be 2 consecutive even numbers , then

(n + 2)² - n² ← is the difference

= n² + 4n + 4 - n²

= 4n + 4

= 4(n + 1) ← a multiple of 4

Answer:

the triangle consists 180 degree
