Step-by-step explanation:

Area of a triangle

The area of a triangle can be calculated using the formula

A = bh/2 where b = base length and h = height

Finding the area by plugging in the values of the height and base length

Looking at the triangle we can tell that the base length is 8 and the height is 10. ( so b = 8 and h = 10 )  

So we have A = bh/2

==> plug in b = 8 and h = 10

A = (8)(10)/2

==> multiply 8 and 10

A = 80/2

==> divide 80 by 2

A = 40

Answer:

A) [tex]x=42\sin32^\circ[/tex]

Step-by-step explanation:

With respect to our angle, the side opposite to it is [tex]x[/tex], and the hypotenuse is [tex]42[/tex], so the trig ratio we need to use here is sine as [tex]\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]. Hence, if we rearrange the equation so that we solve for the opposite side [tex]x[/tex], then we'll have [tex](\text{hypotenuse})(\sin\theta)=\text{opposite}\rightarrow42\sin32^\circ=x[/tex] as the correct equation.

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer:

The answer is 4

[tex]s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }[/tex]

Turn the equation into a simpler form

[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]

[tex]s = \sqrt{\frac{64}{5-1} }[/tex]

[tex]s = \sqrt{\frac{64}{4} }[/tex]

[tex]s = \sqrt{16}[/tex]

That said, we know the square root of 16 is 4, so 4 would be your answer.

Step-by-step explanation:

The Range of the given set is 5.

We have been given Bar Chart that shows how many days it took for 12 corn seedlings to emerge.

We know that the Range of data set is the difference between the smallest and largest values

It is a measure of the spread or variability of the data set.

The highest point is 10

The lowest point is 5

The Range = 10 - 5

Range = 5

Therefore, the correct answer is 5.

Answer:

The answer is 4

Step-by-step explanation: i did it

Step-by-step explanation:

well, the translation (x+6, y+1) creates the following points :

D goes from (-4,-4) to (2,-3)

E goes from (-4,-2) to (2,-1)

A good from (-1,-4) to (5,-3)

the reflection over the x-axis leaves then the x values unchanged, and negative y values turn positive (or vice versa, if we had a case here).

so,

D' = (2,3)

E' = (2,1)

A' = (5,3)

Step-by-step explanation:

8 steps per 10 seconds

How many steps per 4 minutes?

First, find out how many 10-second intervals there are in 4 minutes.

4 minutes = 240 seconds

240 divided by 10 is 24

24 ten second periods times 8 steps per 10 seconds

192

192 steps in 4 minutes

For this, you will just simplify to figure it out. It should be pretty easy.

14/5 is 2 4/5 (2 whole and 4/5 extra)

Step-by-step explanation:

we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.

in other words

h² = p×q

h = height

p, q are the 2 segments of the Hypotenuse.

so, in our case we have

100 = x(x + 21) = x² + 21x

that gives us the following quadratic equation

x² + 21x - 100 = 0

the general solution to a quadratic equating is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 21

c = -100

so,

x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =

= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =

= (-21 ± 29)/2

x1 = (-21 + 29)/2 = 8/2 = 4

x2 = (-21 - 29)/2 = -50/2 = -25

x2 would give us negative lengths for the triangle, which does not make sense.

so, x = 4 is our solution.

that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).

Area = 13

Step-by-step explanation:

see image. There's a brick of 8 whole squares on the bottom. Then a layer of 3 whole squares on top of that. There's a 1/2 a square besides the 3. Then on top, there is half of a layer of 3 squares. Half of 3 is 1 1/2.

8 + 3 + 1/2 + 1 1/2

= 8 + 3 + 2

= 13
