i dont know this

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).

No

Step-by-step explanation:

We can either cross multiply or turn into decimal form to see if they have the same value.

I will be showing both.

Cross Multiply:                                                   Decimal Form:

[tex]\frac{18}{24} \;[\;\;] \frac{10}{15}[/tex]                                                [tex]\mathrm{To\;turn\;fraction\;into\;decimal\;just}[/tex]                                

[tex]18\times15=270[/tex]                                               [tex]\mathrm{Divide\;numerator \;by \;denominator\;}[/tex]

[tex]24\times10=240[/tex]                                                [tex]\mathrm{18\div24=0.75}[/tex]

[tex]\frac{18}{24} \;[ > ] \frac{10}{15}[/tex]                                                           [tex]\mathrm{10\div15=0.66666666666}[/tex]

[tex]\mathrm{As\;a\;result\;we\;can}[/tex]                                             [tex]0.75 > 0.66666666666[/tex]

[tex]\mathrm{conclude\;that\;\frac{18}{24} \;is\;greater\;than\;\frac{10}{15}}[/tex]                     [tex]\frac{18}{24} \;[ > ] \frac{10}{15}[/tex]

We can conclude that 18/24 and 10/15 are not the same.

Step-by-step explanation:

The bathtub had 120 L of water before Barb pulled the plug.

It will take about 9.23 minutes for the water to drain out.

Given equation: L = -5t - 8t + 120

Simplified: L = -13t + 120

Notice how it's written in slope-intercept form (y = mx+b)

The y-intercept (L) is 120. So the coordinates for L = (0 , 120)

The coordinates mean that before the water in the bathtub began draining out, it initially had 120 Liters of water.

Now that we know how many liters there were before, the new equation would look like this: L = -13t --> 120 = -13t

Solving the equation, we get that t = -9.23 minutes

Since time can't be negative, we'll just say that it will take 9.23 minutes to drain out all the water.

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.

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)

Answer:B

Step-by-step explanation:

The requried small section of the solar panel does not have an area of 30.4 inches.

Surface area is defined as the measure of a region or surface is called as surface area.

Identify the problem and find the area of the small section.

Formulate the area using the dimensions provided: (10.4 x 4.8)/2

Solve for the area: (49.92)/2 = 24.96

Contrast the calculated area with the given area: 24.96 is not equal to 30.4.

Finalize the answer: Disagree, the small section of the solar panel does not have an area of 30.4 inches.

Thus, the requried small section of the solar panel does not have an area of 30.4 inches.

Answer:

Answer: 3.75 g

Step-by-step explanation:

Assume the weight of the square is x.

The hanger is in balance so the left side is equal to the right side.

Equation therefore is:

Triangle + Square + 3 * circle = 5* square + circle

3 + x + (3 * 6) = 5x + 6

3 + x + 18 = 5x + 6

5x - x = 3 + 18 - 6

4x = 15

x = 15/4

x =  3.75 g

Step-by-step explanation:

The rower can bring all of them to another side because if he put sheep and wolf along with wolf will eat the sheep.

The process of applying a chain of reasoning to solve a problem and achieve a conclusion is known as logical thinking. It's an effective method for conquering seemingly insurmountable difficulties because it gives you the mental tools you need.

We have:

You want to bring a wolf, a goat, and a cabbage across a river. You are the rower and don't get out of the boat.

The rower first takes the sheep to the other side then again from the starting point he takes the wolf and takes it to another side then picks the sheep to take it to another side then and drops the sheep at the starting point and picks the cabbage then drop it to another side then again pick the sheep and drop to another side.

Thus, the rower can bring all of them to another side because if he put sheep and wolf along with wolf will eat the sheep.

Step-by-step explanation:

The answer choices to this question do not make sense since probability is a measure that is always <= 1.0

Based on the number of times a particular colored tile is drawn we can assume that at the minimum there are 6 green, 20 red, 7 blue, 8 purple and 4 black tiles

Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45

Probability of drawing a green tile = 6/45 = 2/15

Step-by-step explanation:

I look at it more as numbers, so for example 1/2 can be simplified into 50, and 3/4 is 75/ 75 would be greater if it was positive. But, with there being a negative 1 in front of the answer, the lowest number closest to 0 is better. :D
