The answer is -10. I think about negative numbers on a number line with numbers being behind and in front of the zero. To check the answer you can imagine being on -10 and when it says to minus a number you always know that it’s going to go further into the negative. So -10-10 is -20.

In a two digit number, the tens digit is 2 less than the units digit multiplied by 3. The reversed number is half of the original number plus 1/2. What is the original number?

Answers

Answer:

73

Step-by-step explanation:

Original number: XY

x = 3y - 2

10y + x = (10x + y) / 2 + 1/2

substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2

* 2 both sides and simplify: 26y - 4 = 31y - 19

31y - 26y = -4 + 19

5y = 15

y = 3

x = 7

Original number: 73

Step-by-step explanation:

Here, we have three types of equations and three plotted graphs

we have a quadratic equation

an exponential equation

and a linear equation

For a quadratic equation, we usually have a parabola

The first equation is quadratic and as such the first graph that is parabolic belongs to it

For an exponential equation, we usually have a graph that rises or falls before becoming flattened

The second equation represents an exponential equation so the second graph is for it

Lastly, we have a linear equation

A linear equation usually has a straight line graph

Thus, as we can see, the third graph represents the linear equation

The titanic was scheduled to arrive on April 17 after leaving on April 10. About how many product of meat did they have per day?

Answers

Incomplete question. Attached is an image of the missing data.

Answer:

9,375

Step-by-step explanation:

Note, from the table we observed that the total supply of meat on board the ship is stated as 75,000 Pounds. Hence if the "Titanic was scheduled to arrive on April 17 after leaving on April 10," this makes the total intended duration of the trip to be 8 days.

Thus, the average amount of meat did they have per day would be gotten by dividing by 8 days ([tex]\frac{75000}{8} =9,375[/tex]) = 9,375 pounds.

The rate of sales tax on trousers is 10%. One can buy a pair of trousers at $ 660. What is the marked price?

Answers

Answer: $600

Step-by-step explanation:

The marked price is the price of the trouser without a sales tax.

The sales tax is 10% which means it increased the marked price by 10% to get to $660.

Assume that price is x:

660 = (1 + 10%) * x

x = 660/(1 + 10%)

x = $600

find the percent change from the first value to the second. 30; 42​

Answers

Answer:

The percentage change is a 40% increase.

Step-by-step explanation:

Given

Old value = 30New value = 42

To determine

The percent change from the first value to the second

Using the formula

Percentage change = [New value - Old value] / | Old value | × 100

                                 = [42 - 30] / |30| × 100

                                 = 12 / 30 × 100

                                 = 0.4 × 100

                                 = 40% change

                                  = 40% increase

Therefore, the percentage change is a 40% increase.

Answer:

a.) 70*

b.) 60*

Step-by-step explanation:

a.) An isosceles triangle has two angles that are equal. The one other angle is 40*, meaning you have to subtract that from 180 and then divide by 2.

b.) An equilateral triangle has three equal angles. Divide 180 by 3.

The measure of the angle ∠Q and angle ∠M will be 80° and 60°, respectively.

What is an angle?

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

In the first case, the triangle is an isosceles triangle. Then the two angles will be congruent. Then the equation is given as,

∠Q = ∠S                                  ...1

∠Q + ∠R + ∠S = 180°              ...2

From equations 1 and 2, then we have

∠Q + ∠Q + 40° = 180°

2∠Q = 180° - 40°

∠Q = 140° / 2

∠Q = 80°

In the second case, the triangle is an equilateral triangle. Then all the angles of the equilateral triangle are congruent.

∠P = ∠M = ∠N                         ...3

∠P + ∠N + ∠M = 180°              ...4

From equations 3 and 4, then we have

∠M + ∠M + ∠M = 180°

3∠M = 180°

∠M = 60°

The measure of the angle ∠Q and angle ∠M will be 80° and 60°, respectively.

Answer: Zero slope.

Step-by-step explanation: The line does not increase or decrease, so your two options are undefined or zero. If the line were vertical (up and down), the slope would be undefined since there would be many y-values for one x-value. Since the line is horizontal (right to left), though, each x-value only has one y-value. Since the y-value doesn’t change, the slope is zero.
