What is the difference between 5 hundreds and 3 tens?​

Density per square block means the area:

Area = Length x width = 2 x 2 = 4 square blocks.

Now for density divide the population by the area:

1.5 million people / 4 square blocks = 0.375 million people per square block

0.375 million = 375,000

Answer: Choice C

sin(26) = x/10

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

Explanation:

With respect to the 26 degree angle, the x is the opposite side and the 9 is the length of the adjacent side.

We can say tan(26) = x/9 because tangent is the ratio of opposite over adjacent. In other words, tan(angle) = opposite/adjacent

Unfortunately, tan(26) = x/9 is not an answer choice.

Luckily though, we have other trig ratios to work with.

The sine ratio ties together the opposite side and hypotenuse

sin(angle) = opposite/hypotenuse

sin(26) = x/10

---------

Extra info (optional section)

Solving for x leads to...

sin(26) = x/10

10*sin(26) = x

x = 10*sin(26)

x = 4.38371 approximately

Also, note how cos(26) = 0.89879 approximately, which is fairly close to 9/10 = 0.9. This indicates some rounding error is going on when your teacher is displaying either the 9, the 10, or the 26 degree angle.

Answer:

the water will rise 10 in each hour after 4 hours the water will be 40 in deep and it will take 8 hours for the water to reach a depth of 80 in

The water rises 10 inches each hour. The water is 4 inches deep is the water after four hours. It will take 8 hours for the water to reach a depth of 80 inches.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

A pipe cracked overnight and started to leak into a basement.

The graph represents the depth (d) of the water over time (t).

As per the given graph, the required solution would be as:

Take two points (1, 10) and (5, 50) in the given graph

The linear function will be :

d - 10 = (50-10)/(5-1)(t - 1)

d - 10 = (40/4)(t - 1)

d = 10(t - 1) + 10

d = 10t - 10 + 10

d = 10t

Here slope of the given function is 10, which means 10 inches the water rise each hour.

The value of time (t) = 4 hr corresponds to the depth of water (d) is

d = 10(4) = 40

So, the water is 40 inches deep is the water after four hours

The value of depth of water (d) = 80 in corresponds to the time (t) is

80 = 10t

t = 80/10 = 8

So, It will take 8 hours for the water to reach a depth of 80 inches

Answer:

3/4 of a pizza is left.

Step-by-step explanation:

4 pizzas minus (2 and 7/12 plus 2/3). Change 2/3 to 8/12 by multiplying the numerator and denominator by 4 to get both denominators the same. 4 pizzas minus (2 and 7/12 plus 8/12 or 2 and 15/12 or 3 and 3/12 or 3 and 1/4). Restated 4 pizzas minus 3and 1/4 pizzas 3/4 pizzas. 3/4 of a pizza is left.

Answer:

16/52

Step-by-step explanation:

A U B= A + B - A ∩ B

A= 4/52

B= 13/52

A∩B= 1/52 (it's 1/52 because there is only one 7 of diamonds in the deck)

4/52+13/52-1/52= 16/52

Answer:

x ≈ 54.9 units

Step-by-step explanation:

Observe that side x is adjacent to ∠A and side 37 is opposite of ∠A, which we will use the tangent function where tan(θ) = opposite/adjacent:

tan(34°) = 37/x

tan(34°)x = 37

x = 37/tan(34°)

x ≈ 54.9

Therefore, x ≈ 54.9 units

Answer:

[tex]y=-2x+2[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-1, 4) and (0, 2)

[tex]=\frac{2-4}{0-(-1)}\\=\frac{-2}{0+1}\\=\frac{-2}{1}\\= -2[/tex]

Therefore, the slope of the line is -2. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-2x+b[/tex]

2) Determine the y-intercept

[tex]y=-2x+b[/tex]

Recall that the y-intercept is the value of y when the line crosses the y-axis, meaning that the y-intercept occurs when x is equal to 0.

One of the given points is (0,2). Notice how y=2 when x=0. Therefore, the y-intercept of the line is 2.

Plug this back into the equation:

[tex]y=-2x+2[/tex]

I hope this helps!

Answer:

The medals can be awarded in 1,320 possible ways.

Step-by-step explanation:

Given that a gold, a silver, and a bronze medal are awarded in an Olympic event, to determine in how many possible ways can the medals be awarded for a 200-meter sprint in which there are 12 runners, the following calculation must be performed:

12 x 11 x 10 = X

12 x 110 = X

1,320 = X

Therefore, the medals can be awarded in 1,320 possible ways.

Step-by-step explanation:

Answer:

The two restrictions that we have for x are:

x < -2

x > -0.5

Step-by-step explanation:

In part 3 we want to solve:

-5 < f(x) < 1

But we don't know the actual equation of f(x), we have only the graph, so let's work with that.

So with the graph, let's find the allowed values of x.

First, let's see the possible values of x such that:

-5 < f(x)

in the graph, we can see that:

f(-2) = -5

And as x decreases we will have:

f(x) > -5

So here we found one restriction for x, if we want:

f(x) > -5, then we must have x < - 2

Now let's find the other case, where:

f(x) > 1

Again, in the graph we can see that:

f(-0.5) = 1

And as x increases, the value of f(x) decreases.

so if x > -0.5

f(x) < 1.

Then we found another restriction for x:

x > -0.5

The two restrictions that we have for x are:

x < -2

x > -0.5

So if x is a value such that one of these two inequalities is true, then the inequality:

-5 < f(x) < 1

is true.

Step-by-step explanation:

a12 = 45 + (12-1)(-6)

= 45-66= -21

Step-by-step explanation:

yes, the other answer is correct.

just to explain a little bit more :

the sequence is clearly built by subtracting 6 from one element to the next.

in other words :

a1 = 45

a n = a n-1 - 6

in such a sequence you do the same operation/ calculation over and over again - once per new element.

the operation in this example is simple - as mentioned : subtract 6.

a1 just gives us a starting value (no operation done for for it) zu, the operation is done one time less than the running number of the element.

therefore, the general element generation algorithm/ formula is :

a n = a1 - (n-1)*6
