Answer:
B.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
From the 1 and 2, we see that the hypotenuse must be twice the length of the short leg.
From the 1 and sqrt(3) we see that the long leg is sqrt(3) times the length of the short leg.
Now we check for these two ratios in each choice.
A.
1 is twice 1/2. Check
sqrt(3)/2 is sqrt(3) times 2. Check
B.
10 is twice 5, not twice 5/2. This does not check.
C.
2sqrt(2) is twice sqrt(2). Check
sqrt(6) is 2sqrt(2) time sqrt(3). Check
D.
6 is twice 3. Check
3sqrt(3) is sqrt(3) times 3. Check
Answer: B.
Answer:
B
Step-by-step explanation:
Angle ratio = 30 : 60 : 90
Side ratio = x : x√3 : 2x
[tex]A) x = \frac{1}{2}\\\\ \ x\sqrt{3 } = \frac{1}{2}*\sqrt{3}=\frac{\sqrt{3}}{2} \\\\2x = 2*\frac{1}{2}=1[/tex]
True
[tex]C) x = \sqrt{2} \\\\x\sqrt{3}=\sqrt{2} *\sqrt{3} =\sqrt{2*3}=\sqrt{6}\\\\2x=2\sqrt{2} \\[/tex]

A ball is thrown vertically upward from the ground with an initial velocity of 111 ft/sec. Use the quadratic function h(t) = −16t2 + 111t + 0 to find how long it will take for the ball to reach its maximum height (in seconds), and then find the maximum height (in feet). (Round your answers to the nearest tenth.)
Answer:
t=3.5 seconds
Step-by-step explanation:
Given
h(t) = −16t^2 + 111t + 0
h'(t)= -32t + 111
Maximum height occurs when h(t) = 0 and the ball begins to fall
h(t)= -32t + 111=0
-32t + 111=0
-32t=-111
Divide both sides by -32
t=3.46872
Approximately, t=3.5 seconds
Recall,
Maximum height occurs when h(t) = 0
h(t)= -32t + 111=0
= -32(3.46872)+111
= -110.99904+111
= 0.00096 ft
Alex has a block of wood that is in the shape of a prism with the dimensions shown. He cuts a 10-cm square hole through the center of the prism. What is the volume of the remaining solid?
Answer:
1,120
Step-by-step explanation:
Find the volume of the larger figure. This can be represented using the formula for volume.
V = lwh
V = 5*18*18
V = 1620
Now, find the volume of the cut out piece of the wood. We will subtract this from the larger block.
V = lwh
V = 5*10*10
V = 500
Subtract, and you will have your answer.
1620 - 500 = 1,120
Which of the following points lie in the solution set to the following system of inequalities? y < −3x + 3 y < x + 2 (1, −5) (1, 5) (5, 1) (−1, 5)
Answer: (1, −5)
Step-by-step explanation:
Plot the given inequalities on coordinate plane.
For y < −3x + 3, plot y =−3x + 3
At x=0, y= 3
At y =0, 0=-3x+3
⇒ x= 1
so, plot points (0,3) and (1,0) and join to get y =−3x + 3, since inequality has '<' sign, so shade( in red) below line area and line should be dotted.
For y < x + 2, plot y = x + 2
At x=0, y= 2
At y =0, x=-2
so, plot points (0,2) and (-2,0) and join to get y = x + 2, since inequality has '<' sign, so shade( in orange) below line area and line should be dotted.
Now, plot all given points (1, −5) (1, 5) (5, 1) (−1, 5), we can clearly observe that (1, −5) lies in the solution set. (in common shaded region)

The image below shows two dilated figures with lines IJ and JK drawn. If the smaller figure was dilated by a scale factor of 2, what relationship do lines IJ and KL have?
Answer:
IJ = 2*KL
Step-by-step explanation:
Given that the smaller figure was dilated to create the bigger figure with a scale factor of 2, it therefore means, the dimensions of the smaller figure was increased by times 2 of its dimensions to create the bigger figure.
Thus, the relationship that would exist between line IJ and KL, is that IJ is twice the size of KL.
The relationship is: IJ = 2*KL

Answer:
54 km/h
Step-by-step explanation:
From H to G:
Let the distance be x km.
Average speed = distance/time
60 = x/ 3
60*3 = x
x = 180 km
From G to F:
Let the distance be y km.
Average speed = distance/time
45 = y/2
45*2 = y
y = 90 km
From H to F:
Total distance = x + y = 180 + 90 = 270 km
Total time = 3 + 2 = 5 hours
Average speed from H to F
= Total distance/ total time
= 270/ 5
= 54 km/h
Josh has an aquarium 30 inches deep it takes him 5 minutes to fill the bucket with 3 inches of water he estimates that it will take him under an hour to fill the entire bucket with water if you correct explain why or why not
I assume your question should be rephrased as "Josh has a bucket 30 inches deep..."
Josh is correct in estimating that it will take him under an hour to fill the entire bucket with water.
Given:
The bucket is 30 inches deepIt takes Josh 5 minutes to fill the bucket with 3 inches of waterTo find: If Josh is correct in estimating that it will take him under an hour to fill the entire bucket with water
It is given that, to fill the bucket with 3 inches of water, it takes Josh 5 minutes.
Using Unitary method, we can say that, to fill the bucket with 1 inch of water, it takes Josh [tex]\frac{5}{3}[/tex] minutes.
Then, to fill the bucket with 30 inches of water, it takes Josh [tex]\frac{5}{3} \times 30[/tex] minutes.
Solving, we can say that it takes Josh 50 minutes to fill the bucket with 30 inches of water.
Since the bucket is 30 inches deep, we can say that it takes Josh, 50 minutes to fill the entire bucket, which is just under an hour.
So, Josh is correct in assuming that it will take him under an hour to fill the entire bucket with water.

simplfy the given equation using the distributive property 5x + 2(x - 3) = -2(x - 1)
Answer:
x = [tex]\frac{8}{9}[/tex]
Step-by-step explanation:
5x + 2 (x - 3) = -2 (x - 1)
5x + 2x - 6 = -2x +2
5x + 2x + 2x = 2 + 6
9x = 8
x = [tex]\frac{8}{9}[/tex]
Answer:
The value of x in the given equation is 0.89
Step-by-step explanation:
5x + 2(x - 3) = -2(x - 1)
Distribute 2 to (x - 3)
5x + 2x - 6 = -2(x - 1)
Distribute 2 to (x - 1)
5x + 2x - 6 = -2x + 2
Combine 5x and 2x on the left side of the equation.
7x - 6 = -2x + 2
Add 6 on both side of the equation.
7x = -2x + 8
Add 2x on both sides of the equation.
9x = 8
Now divide 9 from 8. Make sure you round the decimal because the quotient of these numbers is a repeating decimal.
x = 0.89
So, the value of x is 0.89
assume the initial velocity is 60 feet/second. what is the maximum horizontal distance possible and at what angle does this occur
Answer:
h = 112.5 feets
Step-by-step explanation:
The equation for horizontal distance "h" in feet of a projectile with initial velocity v₀ and initial angle theta is given by :
[tex]h=\dfrac{v_o^2}{16}\sin\theta\cos\theta[/tex]
We know that, [tex]2\sin\theta\cos\theta=\sin2\theta[/tex]
So,
[tex]h=\dfrac{v_o^2}{32}\sin2\theta[/tex]
Now we need to find the maximum horizontal distance possible and at what angle does this occur.
For maximum distance angle should be 45 degrees. Som,
[tex]h=\dfrac{60^2}{32}\sin2(45)\\\\h=112.5\ \text{feet}[/tex]
So, 112.5 feets is the maximum possible distance.

Answer:
La cantidad inicial que tenía la madre de Rosita antes, comprando los artículos es de $13.90
Step-by-step explanation:
La información dada son;
El valor de la máscara = $ 1.25
El valor del paquete de jabones = $ 2.00
El valor del gel de alcohol = $ 3.00
La cantidad que le quedaba después de pagar = $ 7.65
Por lo tanto, tenemos;
La cantidad inicial que tenía la madre de Rosita antes, comprando los artículos = La cantidad que le quedaba después de pagar + El valor del gel de alcohol + El valor del paquete de jabones + El valor de la mascarilla
Por lo tanto;
La cantidad inicial que tenía la madre de Rosita antes, comprando los artículos = $ 7.65 + $ 3.00 + $ 2.00 + $ 1.25 = $ 13.90.
m-m-1/2=1-m-2/3 ( will mark brainiest)
Answer:
Step-by-step explanation:
m= 1/2
this is answer ..........
hope it helps
pls mark my answer as the brainliest
Answer:
M = 5/6
Step-by-step explanation:
m-m-1/2=1-m-2/3
You combine like terms, in this case, the m-m and 1-2/3.
-1/2 = -m + 1/3
Now you need to isolate the m so you subtract 1/3 from both sides.
-1/3 - 1/2 = -m
Combine like terms again.
-5/6 = -m
But m needs to be positive so you divide both sides by -1.
m = 5/6
This should be the answer!

how to solve 2x(x+3)=2x^2+15
Answer: x = 5/2 = 2.5
Step-by-step explanation:
Given expression
2x (x + 3) = 2x² + 15
Expand parentheses and apply the distributive property
2x · x + 2x · 3 = 2x² + 15
2x² + 6x = 2x² + 15
Subtract 2x² on both sides
2x² + 6x - 2x² = 2x² + 15 - 2x²
6x = 15
Divide 6 on both sides
6x / 6 = 15 / 6
x = 15/6
