The Intuition for why the area of a parallelogram is A=bh (area = base x height)

The formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle.

Answer:

37

Step-by-step explanation:

If she has 24 left, and lost 13, you add 13 and 24 to find the original amount.

Virginia's mother gave her 37 marbles for her birthday.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Virginia's mother gave her marbles for her birthday.

Let number of marbles = x

Here, Virginia lost 13 of them and she has 24 marbles left.

So, We get;

⇒ x - 13 = 24

Solve for x;

⇒ x = 24 + 13

⇒ x = 37

Thus, Virginia's mother gave her 37 marbles for her birthday.

Answer:

Step-by-step explanation:

The null and the alternative hypothesis is:

[tex]H_o: \mu_c \ge \mu_{us}[/tex]

[tex]H_a : \mu_c < \mu_{us}[/tex]

The t- student test statistics can be computed as:

[tex]t = \dfrac{x_c- x_{us}}{\sqrt{\dfrac{\sigma_c^2}{n_c} + \dfrac{\sigma_{us}^2}{n_{us}} }}[/tex]

[tex]t = \dfrac{19- 21}{\sqrt{\dfrac{7^2}{100} + \dfrac{8^2}{130} }}[/tex]

t = -2.017  

degree of freedom = (n₁ - 1) + (n₂ - 1)  

= (100 - 1) + (130 - 1)

= 228

Using the data of t-value and degree of freedom;  

The P-value = -0.224

Decision rule: Do not reject the null hypothesis if the p-value is greater than ∝(0.01)

Conclusion: We reject the null hypothesis since the p-value is less than ∝.

Therefore, there is enough evidence to conclude that the mean age of entering prostitution in Canada is lower than that of the United States.

Step-by-step explanation:

Let x be the number of hours for

the police to catch up to the car.

We have 90x = 80x + 5.

=> 10x = 5

=> x = 0.5.

Hence it will take them 30 minutes.

Answer:

Step-by-step explanation:

Any line will add up to 180 degrees. If you subtract the 165 degrees from 180 (total), you will get the x value.

180 - 165 = 15 degrees

Answer:

The average number of skiers in Lavilla are 1,600 skiers

Step-by-step explanation:

The number of skiers that come to Lavilla on average each week = 2,800 skiers

The number of days each skier stays in Lavilla = 4 days

The amount each skier spends in local restaurants daily = $40

According to Little's Law, we have;

L = λ·W

Where;

L = The average number of skiers in Lavilla

λ = The effective arrival rate of the skiers = 2,800 skiers per week arrive

W = The number of days each skier stays at Lavilla = 4 days = 4/7 week

The average number of skiers in Lavilla, 'L', is therefore, given as follows;

L = 2,800 skiers/weel × (4/7) week = 1,600 skiers

The average number of skiers in Lavilla, L = 1,600 skiers

Answer:

comparing both equation we get,

2X+1=X+9

or, X=8

Y=X+9

or, Y=17

therefore the required solution is (8,17)

Answer:

  slope decreases

Step-by-step explanation:

The slope of a ramp is directly proportional to the rise and inversely proportional to the run. When the run increases, the slope decreases.

Answer: The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. It's a fundamental relation in Euclidean geometry among the three sides of a right triangle.

Step-by-step explanation:

Answer:

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.

The smallest possible value that x could take is -2.

Step-by-step explanation:

Integer values:

Integer values can be either positive or negative, with no decimal parts. The integer set is given by:

{...,-3,-2,-1,0,1,2,3,....}

x>−3

We want the first integer on the number line that is greater than -3. This is -2.

So the smallest possible value that x could take is -2.

Answer:

15 height

Step-by-step explanation:

Answer:

2x^2 + 9x + 4

Step-by-step explanation:

To find the area of a triangle, use the formula, 1/2 · base · height = area.

If we plug the given expressions into the formula, we get

1/2(4x+2)(x+4)

Which simplifies to

(2x+1)(x+4)

=2x^2 + 9x + 4

The ratio from tomatoes to pepper plants is 5:2

Meaning there are 5 tomatoes and 2 pepper plants

In order to find a ratio where there are 6 more tomatoes than pepper plants you will have to multiply.

-----

When the ratio 5:2 is multiplied by 2

it equals 10:4

We can stop here because it is shown that now there are 6 more tomatoes than pepper plants.

-----

So there are:

10 tomatoes

and

4 pepper plants!
