Answer:

10 is the answer

Step-by-step explanation:

You add 3 to 4 getting 7. Adding 3 to 7 gets you 10

Answer:

its 10... 4+3=7+3=10..........

Answer:

As the time increases, the distance from the floor decreases by 40 cm per second. You find 40 by taking (6,1140) and (9,1020). The slope formula is y2 - y1 over x2- x1. Plug in the variables and you get (1020-1140)/(9-6)= -120/3= -40.

Explanation:

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Like terms have something in common that make it able to combine.

For example, simplify \(3x^2*7x^9+24+3y+8\)

You would find like terms

3x^2 * 7x^9 are like terms because they both have x

24 and 8 are like terms because they are numbers

The answer would be \(21x^{11} +32+3y\)

Hope this helps :)

Answer:

  78π m²

Step-by-step explanation:

The lateral area of the cylinder is ...

  LA = 2πrh

  LA = 2π(3 m)(8 m) = 48π m²

The lateral area of one cone is ...

  LA = πrh . . . . where h is the slant height

  LA = π(3 m)(5 m) = 15π m²

Then the total surface area of the figure is the area of the two cones plus that of the cylinder:

  S = 2(cone area) + cylinder area

  S = 2(15π m²) +(48π m²)

  S = 78π m²

Based on the above, there are 26 rabbits after 1 week.

There are 33 rabbits after 8 weeks.

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.

For example, after 1 week, we have:

r = 25 + w = 25 + 1 = 26

So there are 26 rabbits after 1 week.

Similarly, after 8 weeks:

r = 25 + w = 25 + 8 = 33

So there are 33 rabbits after 8 weeks.

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

Answer: 2

Step-by-step explanation:

Slope is rise over run. So if we look at the points (1,1) and (0,3), you can see that it goes up by 2 units and over one unit, leaving you with "2/1", which is equivalent to 2.

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answer: 6 lenses

Step-by-step explanation:

1 pair of glass=2 lenses

3 glasses=3 pair of glasses

3 pairs of glasses*2 lenses/1 pair of glass=6 lenses in 3 pair of glasses

Answer:

6

Step-by-step explanation:

A pair of glasses usually contains 2 lenses. The equation y=2(x) is equal to the amount of lenses she would have. If y=total lenses and Mariana has 3 pairs then that means y=2(3) and 2(3)=6. Therefore y=6.

This is assuming that the glasses are single lense.

To find the cost per day, we have to divide the total cost by the number of days:

380/2.5 = 152

The experimental and theoretical probabilities are considerably different. This has to do with the small number of trials. For a higher number of trials, the experimental probability should be very close to the theoretical probability of 0.1429.

Answer:

photo 1: D. a + b = 180

photo 2:

a. interior angles of a triangle

b. vertical angles

c. complementary angles

d. supplementary angles

photo 3:

a. 82

b. 82

photo 4:

a. 51

b. 129

photo 5: x = 60

Step-by-step explanation:

The interior angles of a triangle are the angles that are inside the triangle and are formed by the intersection of two sides of the triangle. In a triangle, there are always three interior angles.

The sum of the interior angles of a triangle is always 180 degrees. This is because the interior angles of a triangle are supplementary, meaning that they add up to 180 degrees.

Vertical angles are two angles that are opposite each other and are formed by two intersecting lines. The lines that intersect to form the vertical angles are called "arms" of the angles.

Vertical angles are always congruent, which means that they have the same measure

Complementary angles are two angles whose measures add up to 90 degrees. In other words, if two angles are complementary, then one angle is the complement of the other.

Supplementary angles are two angles whose measures add up to 180 degrees. In other words, if two angles are supplementary, then one angle is the supplement of the other.

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

\(3(x - 2) + 7x = \frac{1}{2} (6x - 2)\)

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

\(3x - 6 + 7x = 3x - 1\)

Now, we would shift all x terms to the left and all number terms to the right.

\(3x + 7x - 3x = - 1 + 6\)

After simplifying, the final equation would be:

\(7x = 5\)

This is a linear equation and it has one solution.

Answer:

Angle O = 72°, Angle M = 18°, Angle N = 90°

Step-by-step explanation:

According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.

given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°

. Angle M + 5(Angle M) + 4(Angle M) = 180°

10(Angle M) = 180°.

then you divide. Angle M = 18°

with this statement. you can substitute this into the other equations to get the other answers.

5(18°) = Angle N, 4(18°) = Angle O.

90° = Angle N, 72° = Angle O.
