Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

Isolate x by taking the log of each side:

[tex]\frac{1}{4}=2^x\\log_2(\frac{1}{4})=log_2(2^x)\\x=-2[/tex]

This works because:

[tex]2^{-2} =\frac{1}{2^{2}}=\frac{1}{4}[/tex]

If this helped, a brainliest would be greatly appreciated!

Answer:

7.744

Step-by-step explanation:

3.20=3.2

you can multiply just 242 and 32 then pop in the decimal point later

242*32=242*30 + 242*2

242*3*10=726*10=7260

242*2=484

7260+484=7744

2*3 (rounded version of numbers) is 6

so the answer after putting decimal point should be around 6

77.44 is way too hight

7.744 is decently close to 6

so the answer is 7.744

Answer:

1/4

Step-by-step explanation:

Given

amount of  salamanders, = 5

amount of crayfish = 3

amount of minnows = 12

Total fish = Total outcome = 5+3+12

Total outcome = 20

Since we are looking for the probability of selecting  salamanders, our expected outcome will be 5.

Probability = expected outcome/total outcome

Pr( salamanders,) = 5/20

Pr( salamanders) = 1/4

Hence the probability of selecting  salamanders, is 1/4

Hope this helps and best of luck!!

Answer:

5 1/5 miles

Step-by-step explanation:

Given that :

Library is located halfway between park and home ;

Distance between library and park = 1 3/10 miles

Hence, total distance between park and home :

1 3/10 + 1 3/10 = 2 6/10

The distance driven :

Home to park ; park back home

2 6/10 + 2 6/10 = 4 12/10

4 + 12/10 = 4 + 1 2/10

= 5 2/10

= 5 1/5 miles

Answer:

2/5

Step-by-step explanation:

slope is change in y/change in x

4-2 / 3+2 = 2/5

Answer:

m = 2/5

Step-by-step explanation:

(-2, 2) and (3, 4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4 - 2)/(3 + 2)

m = 2/5

Answer:

80%p=d

Step-by-step explanation:

20% discount is 80% of original.

An equation for the relationship between the discount price of an item, d, and it's original price, p is p = 0.8d.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A store is offering a 20% discount on all items.

Let the discount price of an item, d, and it's original price, p.

The original price = (100 - 20%)discount price

p = 80%d

p = 0.8d

Therefore, p = 0.8d is the required equation.

Answer:

1/2

Step-by-step explanation:

bc 4/10 + 1/10= 5/10 divided by 2 =1/2

Answer:

1/2 or 5/10

Step-by-step explanation:

When you are adding fractions you only add the numerator (the top number) 4+1=5. So you get 5/10. But then you have to divide to get the simplest form. You can divide 10 and 5 by 5. So then after you are done dividing you end up with 1/2!

Answer:

true

Step-by-step explanation:

For 3 sides to be able to form a triangle, we need to check that the 2 shorter sides can "touch" when "stemming" out of the long side.

The long side has length 7cm, so the sum of 2 shorter sides must be bigger than 7cm for them to "touch". Note: if the sum was 7cm, the only way they would touch is if they were laid along the long side, so it would not be a triangle - it would be a segment.

Fortunately, 3cm + 5cm > 7cm, so we can form a triangle.

Answer:

Step-by-step explanation:

A1. C = 104°, b = 16, c = 25

Law of Sines: B = arcsin[b·sinC/c} ≅ 38.4°

A = 180-C-B = 37.6°

Law of Sines: a = c·sinA/sinC ≅ 15.7

A2. B = 56°, b = 17, c = 14

Law of Sines: C = arcsin[c·sinB/b] ≅43.1°

A = 180-B-C = 80.9°

Law of Sines: a = b·sinA/sinB ≅ 20.2

B1.  B = 116°, a = 11, c = 15

Law of Cosines: b = √(a² + c² - 2ac·cosB) = 22.2

A = arccos{(b²+c²-a²)/(2bc) ≅26.5°

C = 180-A-B = 37.5°

B2. a=18, b=29, c=30

Law of Cosines: A = arccos{(b²+c²-a²)/(2bc) ≅ 35.5°

Law of Cosines: B = arccos[(a²+c²-b²)/(2ac) = 69.2°

C = 180-A-B = 75.3°

Answer:

[tex]A=3.125\ cm^2[/tex]

Step-by-step explanation:

Given that,

The base of the parallelogram, b = 2.5 cm

Height of the parallelogram, h = 1.25 cm

We need to find the area of the logo. The formula for the area of the parallelogram is given by :

[tex]A=b\times h\\\\A=2.5\times 1.25\\A=3.125\ cm^2[/tex]

So, the area of the logo is [tex]3.125\ cm^2[/tex].

Answer: The correct answer is A

Step-by-step explanation:

At 1, there is a start of $45

Then for 2 it adds $25

Then 3 adds $25 dollars.

Because 1 started at $45, that means it is a rate of 25 dollars per hour, but a starting cost of 20+25= $45.

Answer:

656

Step-by-step explanation:

Given data

Initila population= 490

Rate = 6%

TIme= 5 years

Let us apply the compounding expression

A=P(1+r)^t

substitute

A= 490(1+0.06)^5

A=490(1.06)^5

A=490*1.338

A= 655.62

Hence the approximate Quail population will be 656
