Step-by-step explanation:

We can call the original value x. In 2012, the painting's value was 1.05 x. In the beginning of 2013, the value was (1.05 x) * 0.98, and that increased to (1.05x) * 0.98 * 1.40 at the end of 2013. When we simplify, we get 1.4406 x as a value, and we know that this is equal to $52,640. We can write 1.4406x = 52640, and when we solve for x, we get x ≈ $36415.38. Hope this helps!

An equation is formed of two equal expressions. The correct option is D.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Amit solved the equation 5/12=-x/420 using the steps. Therefore, The equation can be solved as,

[tex]\dfrac{5}{12} = -\dfrac{x}{420}\\\\\dfrac{5}{12} \times (-420) = -\dfrac{x}{420}\times (-420)\\\\[/tex]

x = -175

Answer:

4.167%

Step-by-step explanation:

Given: It was predicted that it will take 23 minutes to drive to grandma's house but it actually takes 24 minutes.

To find: percent error

Solution:

Predicted time = 23 minutes

Actual time = 24 minutes

Error is the difference between Approximate and Exact Value. Percentage Error is used to compare an estimate value to an exact value.

Error = 24 - 23 = 1 minute

Percent error = (error/actual time) × 100

= 4.167%

Answer:

32hr and 30 mins

Step-by-step explanation:

since the kid goes to to school for 6hr and 30 mins

that should be multiplied by 5

school is on weekdays

that 5 days

6 X 5 = 30hr

30 X 30 = 150mins =2hr and 30 mins

Answer:

It's equal to 1 day, 8 hours, and 30 minutes. But, if you're only counting the hours it's 33 hours.

Answer: 6 gallons

Step-by-step explanation:

4/30  * 45  = 6

Step 1) Divide the figure into separate shapes

Triangle: 4 x 4

Large rectangle: 19 x 8

Small rectangle: 7 x 5

Long rectangle: 4 x 7

Step 2) Find the area of each shape

Triangle: A = 1/2 x 4 x 4 = 8

Large rectangle: A = 19 x 8 = 152

Small rectangle: A = 7 x 5 = 35

Long rectangle: A = 4 x 7 = 28

Step 3) Add all of the areas of the shapes together

A = 8 + 152 + 35 + 28 = 223 square feet

Answer:

The y intercept is (0,-3)

Step-by-step explanation:

The y intercept is when x =0

f(x) = - x^2 + 4x - 3

f(0) = 0 +0 -3

f(0) =-3

The y intercept is (0,-3)

Answer:

c ≈ 6.08 m

Step-by-step explanation:

Your question is how to solve for a missing side length of a triangle when given 2 sides length and an angle. The side length can be solved using the cosine rule . We use cosine rule to find the length of a side of a triangle when given two sides and an included angle.

The cosine rule formula for finding a side length are as follows

c² = a² + b² - 2ab cosC

b² = a² + c² - 2ac cosB

c² = a² + b² - 2ab cosC

Using cosine rule

c² = 4² + 3² - 2 × 4 × 3 cos 120°

c² = 16 + 9 - 24 cos 120°

c² = 25 - 24 (-0.5)

c² = 25 + 12

c² = 37

square root both sides

c = √37

c = 6.0827625303

c ≈ 6.08 m

Answer:

Step-by-step explanation:

262

You’ve done bulk of the work by inserting a straight line through x.

Now, the point at which we have x, has 2 other angles

This makes 3 angles in total which add up to 360( sum of angles at a point)

36 is an alternate angle to one of the angles while 62 is also an alternate angles to one of the angles.

Since alternate angles are equal, the angles are 62 and 36

Thus the angle would be x + 62 + 36 = 360

which makes x = 262

Answer:7

Step-by-step explanation:

p = 7000 is the amount deposited, aka the principal

r = 0.15 is the decimal form of 15% interest rate

t = 2 is the number of years the money sits in the account

--------------

B = p*(1+r)^t

B = 7000*(1+0.15)^2

B = 7000*(1.15)^2

B = 7000*(1.3225)

B = 9257.50

Subtract off the deposited amount to get the interest earned

i = B - p = 9257.50 - 7000 = 2257.50

Answer:

3.5 repeating

Step-by-step explanation:

Answer:

Width = 4.5

Length = 7.5

Step-by-step explanation:

The perimeter is two times the length plus two times the width.

So 2(x+3) + 2x = 24 is the equation to solve.

2x+6+2x = 24

4x = 24-6

4x = 18

x = 9/2= 4.5

So the width = 4.5

Length = 4.5+3 = 7.5

Answer:

Length = 7.5 and width =- 4.5.

Step-by-step explanation:

We have the equation:

P = 2L  + 2W   where P = perimeter, L = length and W = width.

Here P = 24, L = x + 3 and W = x

So plugging in the given values:

24 = 2(x + 3) + 2x

4x + 6 = 24

4x = 24 - 6 = 18

x = 4.5.

So  the dimension ar length = x + 3 = 7.5 and width = 4.5.

Answer:

A) 25

Step-by-step explanation:

12.5 x 2 = 25

- if 50 percent is 12.5

then 100 percent is 12.5 x 2

Answer:

A. 25

Step-by-step explanation:

50% of 25 is 12.5. The word, "of" can be used as multiplying. 50% in decimal form is 0.5, and you multiply 0.5 times all of the answers until you get 12.5 as the answer, which is why A is correct.

Answer:

mean- 32.4

median- 31.5

mode- 35

Step-by-step explanation:

to find mean add up all the number together than divide it by how many number that are there

for example the total is 324 and you would divide it by 10 (since there are 10 number there)

to find median locate the middle number but since you have two number in the middle take those to number add them together and divide by 2

for example 31+32=63 than divide by 2 which is 31.5

to find mode it is the number that appears most often so it would be 35 since it appears most often

Answer:

Probability of picking an even and then even number = [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

Probability of picking a card with even number,

P(even 1) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex] = [tex]\frac{\text{even cards}}{\text{Total number of cards}}[/tex]

               = [tex]\frac{2}{4}[/tex]

               = [tex]\frac{1}{2}[/tex]

Followed by picking a card which is even without putting the first card back.

So an even card is to be picked out of remaining 3 cards.

P(even 2) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]

                = [tex]\frac{1}{3}[/tex]

Now probability of both events = P(even 1) × P(even 2)

= [tex]\frac{1}{2}\times \frac{1}{3}[/tex]

= [tex]\frac{1}{6}[/tex]

Therefore, probability of both the events will be [tex]\frac{1}{6}[/tex].
