Answer:

Infinite

Step-by-step explanation:

Answer:

Step-by-step explanation:

1/3*X +1/4*X = 1

         Use common denomination of 3*4=12

          (4X + 3X) / 12  =  1  This implies that 7X/12 = 1.

Solving for X you get X=12/7 = 1.71 hours is the answer.

Answer:

x - 81 = 321

adding 81 on both sides

x-81+81= 321+81

x= 402

Answer:

402

Step-by-step explanation:

81+321=402-321=81 n=402

Answer:

  66 cm²

Step-by-step explanation:

The area of the polygon is the sum of the areas of the triangle and the rectangle it sits on. The dimensions of the triangle can be found by examining the top/bottom dimensions shown and the left/right dimensions shown.

The width (base) of the triangle is the difference between the lengths of the bottom and top horizontal lines: (12 -9) cm = 3 cm.

The height of the triangle is the difference between the lengths of the left and right sides of the figure: (9 -5) cm = 4 cm.

The dimensions of the rectangle are shown a the bottom and the left sides of the figure.

  triangle area = 1/2bh = 1/2(3 cm)(4 cm) = 6 cm²

  rectangle area = LW = (12 cm)(5 cm) = 60 cm²

Total polygon area = 6 cm² + 60 cm² = 66 cm²

The difference between the depths in February and July is D. 13 feet.

From the information illustrated, it was stated that the depth of a local lake average 26 ft is represented as |−26|. In February, it measured 5 ft deep, or |−5|, and in July, it was 18 ft deep, or |−18|.

Therefore, it should be noted that the depth in July is -18.

Therefore, the difference between the depths in February and July will be:

= -5 - (-18)

= -5 + 18

= 13

Therefore, the depth is 13 feet.

Answer:

there are 52 cards in a deck so the chance is a red card (or not a red card) is 26 out of 52.

Step-by-step explanation:

The solution is 12/13

The probability that the selected card is not an ace but a red card is 12/13

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

Let the probability of the selected card is not an ace but a red card be P

Now , the equation will be

Mason randomly chooses a card from a standard deck of playing cards

So , the probability that the card is a red card is

There are 26 red cards in the deck of 52 cards

So , the probability of selecting a red card = 26/52

Now , from the 26 red cards , the probability that the card is not an ace would be = 26 - ( Ace of hearts + Ace of diamonds )

And ,

The probability of the selected card is not an ace but a red card P = 24/26

The probability of the selected card is not an ace but a red card P = 12/13

Therefore , the value of P is 12/13

Hence , the probability is 12/13

Answer:

17cm

Step-by-step explanation:

Given that the Volume of a cone is 4,000 cm³. And we need to determine the height of the cone , if the diameter is 30cm .

Diagram :-

\(\setlength{\unitlength}{1.2mm}\begin{picture}(5,5)\thicklines\put(0,0){\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\put(-0.5,-1){\line(1,2){13}}\put(25.5,-1){\line(-1,2){13}}\multiput(12.5,-1)(2,0){7}{\line(1,0){1}}\multiput(12.5,-1)(0,4){7}{\line(0,1){2}}\put(17.5,1.6){\sf{15cm }}\put(9.5,10){\sf{17\ cm }}\end{picture} \)

Step 1: Using the formula of cone :-

The volume of cone is ,

\(\rm\implies Volume_{(cone)}=\dfrac{1}{3}\pi r^2h \)

Step 2: Substitute the respective value :-

\(\rm\implies 4000cm^3 =\dfrac{1}{3}(3.14) ( h ) \bigg(\dfrac{30cm}{2}\bigg)^2 \)

As Radius is half of diameter , therefore here r = 30cm/2 = 15cm .

Step 3: Simplify the RHS :-

\(\rm\implies 4000 cm^3 = \dfrac{1}{3}(3.14) ( h ) (15cm)^2\\ \)

\(\rm\implies 4000 cm^3 = \dfrac{1}{3}(3.14) ( h ) 225cm^2\\ \)

Step 4: Move all the constant nos. to one side

\(\rm\implies h =\dfrac{ 4000 \times 3}{ (3.14 )(225 )} cm \\\)

\(\implies \boxed{\blue{\rm Height_{(cone)}= 16.98 \approx 17 cm }}\)

Hence the height of the cone is 17cm .

-3(h+5) + 2 = 4(h+6) -9

-3h-5 + 2 = 4h+24 -9

-3h-4h = 24-9+5-2

-7h = 18

h = -18 = -2.57

Answer:

- 1 1/3

Step-by-step explanation:

To solve this, simply divide 4 by -3. 4/-3 = -1 1/3, so that's your answer.

Answer:

x = 4

Step-by-step explanation:

Because we know both figures have the same perimeter, we can set them equal to each other.

3x + 4 + 5x + 1 + 2x + 5 = x + 13 + x + 13 + 2x + 2x

10x + 10 = 6x + 26 (Added like terms.)

4x + 10 = 26 (Subtracted 6x on both sides.)

4x = 16 (Subtracted 10 on both sides.)

x = 4 (Divided 4 on both sides.)

Answer: 1085

Step-by-step explanation:

The given equation is

We know that line v is perpendicular to u (the given equation).

The definition for perpendicularity in this case is

Additionally, from the given equation, we know that the slope of line u is 3/8. Using the perpendicularity definition, we have

∫ (2x + 2)⁵ dx

Substitute u = 2x + 2, so that du = 2 dx. Then

∫ (2x + 2)⁵ dx = ∫ u ⁵ (du/2) = 1/2 ∫ u ⁵ du

Use the power rule:

1/2 ∫ u ⁵ du = 1/2 (1/6 u ⁶) + C = 1/12 u ⁶ + C

Replace u to get the antiderivative back in terms of x :

∫ (2x + 2)⁵ dx = 1/12 (2x + 2)⁶ + C

and the result can be simplified a bit as

(2x + 2)⁶ = 2⁶ (x + 1)⁶

→   ∫ (2x + 2)⁵ dx = 2⁴/3 (x + 1)⁶ + C = 16/3 (x + 1)⁶ + C

The inequality x < -2 means that any number

less than -2 is a solution to the inequality.

For example, -3 is a solution because -3 is less than -2.

Another solution would be -16 because -16 is less than -2.

One other solution would be -642,000 because it's less than -2.

Answer:

B. 1/3

Step-by-step explanation:

This question is designed to show if you know the exponent rules. Exponent Rules are short cuts. If you are multiplying two terms and they both have the same base (the big bottom number), then you could ADD the exponents (the small font raised numbers) Here the base is 3 in both terms. We keep that base. Then add 2/5 and -7/5 to get -5/5. This is just -1.

Another Exponent Rule is how to use negative exponents. So far we have 3^-1 (that means three to the negative one power)

In order to make that negative exponent positive, you just move it across the fraction bar. So we would lower it below the fraction bar to make it a positive one exponent. So you end up with 1/3
