Step-by-step explanation:

....................

Answer:

Percent Increase

Step-by-step explanation:

Percent Increase because if the necklace was bought for $260, and was marked up by 30%, it means it was originally a lower price, that was multiplied by 130%.

Explanation by algebra:

x + 0.30x = 260

1.3x = 260

x = 260/1.3

x = 200

The necklace was originally $200, and it was marked up by 30$, making it $260.

Answer:

ans is 504m²

Step-by-step explanation:

given = side of square=18m

height of triangle=12m

formula= surface area of square + surface area of 4 triangles

surface area of square = 4 × length

= 4×18

=72m²

surface area of triangle = 1/2×base ×height

= 1/2×18×12 ( the base lies on the side of the squre so the base is also 18m)

= 108m²

therefore, surface area of 4 triangles = 4×108=432m²

therefore the surface area of the given figure= surface area of aquare + surface area of the 4 triangles

surface area of square= 72 +432

=504m²

Answer:

  after 2 seconds

Step-by-step explanation:

We want to find t such that h = 0.

 0 = -16t² +8t +48

  0 = 2t² -t -6 . . . . . . . divide by -8

  0 = (t -2)(2t +3) . . . . factor

The only positive solution is t = 2, which makes the first factor zero.

x=10

Step-by-step explanation:

x-1 = 9

add 1 on both side

x-1+1=9+1

x=10

Answer:

The answer would be 10

Step-by-step explanation:

1) Add 1 to both sides.

[tex]x = 9 + 1[/tex]

2) Simplify 9 + 1 to 10.

[tex]x = 10[/tex]

Hence, the answer would be 10.

Answer:

  13

Step-by-step explanation:

4 m is 400 cm, so the number that can be cut is ...

  (400 cm)/(30 cm/piece) = 13 1/2 pieces

13 pieces can be cut that are 30 cm long.

Answer:

13 whole pieces

Step-by-step explanation:

4m=400cm

400cm÷30cm=13.333333

you can't get 0.33333333(goes on forever) of a ribbon so its 13

Answer:“ C ”

“month” on the x axis and “log” on the y axis

Answer:

Step-by-step explanation:

Let us begin by just getting the equation of the circle first.

(x - 4)^2 + ( y - 2)^2 = 5^2

(x - 4)^2 + ( y - 2)^2 = 25

Now I'm going to graph that equation and discuss it here.

Answer:

Step-by-step explanation:

Correct answer

Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.

This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.

It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the one-digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:

9.7 + 8.6 which results to 18.3

9.6 + 8.7 yields 18.3 as well.

For the value of the difference to be largest, the minuend should be maximum(most possibly) and the subtrahend should be minimum

[in A-B=X, A is minuend and B is subtrahend ]

So, $a.b should be the maximum. as there is a condition that 4 digits should be distinct, the product will be maximum if we choose 2 maximum valued numbers from the given numbers. so, one of them should be 9 and the other should be 8.

Therefore, $a.b=9*8=72

As mentioned above, c.d$ should be minimum. this will be possible only when we choose  2 minimum valued numbers from the given numbers. so, one of them should be 1 and the other should be 2.

Therefore, c.d$ = 1*2 = 2

Hence, the difference = 72-2 = 70

Thus,  the largest possible value of the difference $a.b - c.d$ = 70

Answer:

8.6

Step-by-step explanation:

The units digits matter most, so we make a as large as possible (a=9) and make c as small as possible (c=1). Then we can use any of the digits from 2 through 8. We still want b as large as possible and d as small as possible so we set b=8 and d=2. This gives a maximum possible difference of 9.8 - 1.2 = 8.6.

Answer: amplitude and period are two different things. The amplitude is -1/3, and the period is 360 degrees.

Step-by-step explanation: to find the amplitude, you just look at what number is in front of sin. If there isn't one, an amplitude of 1 is implied (in this case. Keep in mind that different functions have different standards).

To find the period, you take term b (which is what comes after sin). In this case, b is 1 because there's no specific number there. Again, it's implied. Because this is sin and not tan, for example, you take 360/b=period. 360/1=360 degrees.

Answer: Each friend ran 3.75 miles.

Step-by-step explanation:

Cecil and three friends is equal to 4 people. There are fifteen miles in the full relay. 15 divided by 4 is equal to 3.75.

15/4=3.75

So, the answer is each friend ran 3.75 miles.

Answer: $1,947.75

Step-by-step explanation: First, the mark up is 110% of the total, which is $875. 110% of 875 is $962.50, which you add to the total ($875) since it is mark up. $962.50 + $875 = $1837.50. Finally, 6% of $1837.50 is $110.25 so you add this to your new price ($1837.50) since the 6% is the sales tax. $1837.50 + $110.25 = $1947.75

The balancing point is 23

Step-by-step explanation:

Given

The above graph

Required

Determine the balancing point

This simply means that we calculate the mean.

From the above graph, we have:

[tex]\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}[/tex]

So, the mean is:

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

[tex]\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}[/tex]

[tex]\bar x = \frac{230}{10}[/tex]

[tex]\bar x = 23[/tex]

Hence, the balancing point is 23
