Answer:

-3

Step-by-step explanation:

Adding a negative number is like subtracting. Subtracting more than the original positive number gets you in to the negative numbers.

Answer:

(10^11)/3

10^6 x 10^5 = 10^11

8/5 x 5/24 = 1/3

so multiply 10^11 and 1/3 together

The solutions for the systems of inequalities are:

a) (0, -50), (0, -100), (0, -125)

b)  (0, 20), (0, 23) , (0, 24).

When we have a system of inequalities, a solution is a point (x, y) that solves both ienqualities at the same time.

The first one is:

y ≤ x - 8

y < -3x - 9

Here y must be smaller than x, then we can define x like x = 0, and really small values for y, like y = -50, replacing that we will get:

-50  ≤ 0 - 8 = -8

-50 < - 3*0 - 9 = -9

Both of these are true, so (0, -50) is a solution, and trivially, other solutions of the system of inequalities can be things like (0, -100) and (0, -125) are other two solutions.

For the second system:

y > 5x + 1

y > 3

Let's do the same thing, x = 0 and y gets really large values, like y = 20

20 > 5* + 1 = 1  this is true.

20 > 3   this is true.

so (0, 20) is a solution, and also are (0, 23) and (0, 24).

a) The simplified expression to represent the number of sweets Jack has left after eating 2c sweets is: \(\displaystyle 9c-2c\).

b) To find how many sweets Jack has left if \(\displaystyle c=3\), we substitute \(\displaystyle c=3\) into the expression: \(\displaystyle 9(3)-2(3)=27-6=21\).

Therefore, if \(\displaystyle c=3\), Jack has 21 sweets left.

============================

Explanation:

Start with 9c and subtract off 2c to get 9c-2c = 7c.

We can think of it like 9 candies - 2 candies = 7 candies. Replace each "candies" with "c" so things are shortened.

Afterward, plug in c = 3 to find that 7c = 7*3 = 21

Answer:

116.11 square centimeters

Step-by-step explanation:

subtract area of the big circle with the little circle

formula

area is pi times radius squared

big circle

pi times (6.5 times 6.5) =

132.73

small circle

pi times (2.3 times 2.3) =

16.62

132.73 - 16.62 = 116.11

Answer:

messy... but hope it helps you.

The radius is approximately 3.78 inches.

We can solve the question using the formula for the surface area of a sphere:

S=4πr^2

We are given that the surface area is 225 square inches, so we can substitute this value into the formula and solve for r:

\(225=4\pi r^2\frac{225}{4\pi}\)

      = r^2

r={{225}{4π}}

approx  3.78

A sphere does not have any edges or vertices, like other 3D shapes. The points on the surface of the sphere are equidistant from the center.

Hence, the distance between the center and the surface of the sphere are equal at any point. This distance is called the radius of the sphere.

The Radius of a circle or sphere is equal to the Diameter divided by 2.

Answer:

-3.4p + 3p + 4

Step-by-step explanation:

Solve the parenthesis with the minus sign in front of it. Basically, inverse all of the operations within the parenthesis.

The -3q will become a 3q and the -4 will become a 4.

So now with the positive 3q and 4, you will just add those to the -3.4p

Therefore, the answer is -3.4p + 3p + 4

Answer:

c. w=5

Step-by-step explanation:

It is c because if you replace the variable W with 5, then you would solve the eqaution 50/5 which whill give you the answer 10!

Answer:

C. w = 5

Step-by-step explanation:

Set the expression equal to 10 and solve for w.

\(\frac{50}{w}=10\)

Multiply both sides by w to get the variable out of the denominator.

\((w)\frac{50}{w}=10(w)\)

\(50=10w\)

Finally, divide 10 on both sides to solve for w.

\(\frac{50}{10}=\frac{10w}{10}\)

\(5=w\)

The key to solving problems involving scale drawings lies in understanding the concept of scale factor and using proportional relationships to find missing measurements or determine the actual size of objects.

When working with scale drawings, it is essential to comprehend the concept of scale factor. The scale factor represents the ratio of the measurements on the drawing to the corresponding measurements in the actual object. To solve problems involving scale drawings, start by identifying the given measurements and scale factor. Then, use proportional relationships to set up ratios between the measurements on the drawing and the actual object. By setting up these ratios, you can establish an equation and solve for the unknown measurement. For example, if the drawing shows a length of 5 centimeters with a scale factor of 2:1, you can set up the equation 5/2 = x/1, where x represents the actual length. Cross-multiplying and solving for x will give you the actual length. Additionally, you can use the scale factor to determine the actual size of objects. By multiplying the measurements on the drawing by the scale factor, you can find the corresponding measurements in the actual object. Remember to convert units if necessary and pay attention to any specific instructions or information given in the problem. By applying these techniques, you can effectively solve problems involving scale drawings.

The loan balance after 3 months if the interest is compounded monthly and payments are $88.13 each month is $3996.48

Given that a car is purchased for $4100 and it is paid through a loan, and the amount of monthly payments and interest rate are provided.

We have to determine the loan balance after 3 months if the interest is compounded monthly and payments are $88.13 each month.

Let's first find the interest rate: If R is the annual interest rate, then the monthly interest rate r is given as: r = R/12%So, r = 5.6%/12, which is equal to 0.46667% monthly. Next, let's determine the loan balance after 1 month:

Since the interest is compounded monthly, the balance after one month is given as: Balance after 1st payment = $4100 × (1 + 0.0046667) - 88.13

Balance after 1st payment = $4065.67

Now let's determine the loan balance after 2 months:

Balance after 2nd payment = $4065.67 × (1 + 0.0046667) - 88.13

Balance after 2nd payment = $4030.97

Finally, let's determine the loan balance after 3 months:

Balance after 3rd payment = $4030.97 × (1 + 0.0046667) - 88.13Balance after 3rd payment = $3996.48

keeping in mind that in a rhombus the diagonals always meet at right-angles, Check the picture below.

The maximal number of intersection points outside the circle that can be created by connecting the 7 dots on the circle with lines is 21.

To calculate this, we use the formula for the maximum number of intersection points formed by connecting n points with lines:

Max intersection points = n * (n - 1) / 2

In this case, n = 7, as there are 7 dots on the circle. Plugging in this value into the formula:

Max intersection points = 7 * (7 - 1) / 2

Max intersection points = 7 * 6 / 2

Max intersection points = 42 / 2

Max intersection points = 21

Therefore, the maximal number of intersection points outside the circle formed by connecting the 7 dots on the circle with lines is 21.
