which of the following are valid names for the given triangle ? check all that apply
Answer: B. ΔMLZ
D. ΔLMZ
E. ΔZML
Step-by-step explanation:
In the given picture we have one triangle with three vertices as
Vertex L
Vertex M
Vertex Z
To name a triangle we use the labels of the vertices of the triangle, which are commonly written in capital letters.
When we name a triangle, we can start with any vertex but we need to keep the letters in order as you go around the triangle.
Therefore, the possible names of the triangle are :-
ΔLMZ Δ LZM ΔMLZ ΔMZL ΔZLM ΔZML

solve(3/4x=1/5, x=_)
Final answer:
To solve 3/4x = 1/5, cross multiply and simplify to get 15 = 4x. Divide both sides by 4 to find x = 3.75 or 15/4.
Explanation:
To solve the equation 3/4x = 1/5, we need to find the value of x that makes the equation true. First, we will cross multiply to get rid of the fractions. We multiply both sides of the equation by 4x and by 5, resulting in 5 × 3 = 4x × 1, which simplifies to 15 = 4x.
To find the value of x, we then divide both sides of the equation by 4, yielding x = 15/4. Therefore, the solution to x is 3.75 or ⅔.

Triangle JKL is isosceles. The meansure of angle J is 72degrees and the measure angle K is 36 degrees. Which satement describes angle L?
Angle L in triangle JKL is [tex]\( 180^\circ - (72^\circ + 36^\circ) = 72^\circ \)[/tex]. Therefore, angle L measures [tex]\( 72^\circ \).[/tex]
1. Start with the fact that triangle JKL is isosceles, which means that angles J and K are congruent.
2. Given that angle J measures [tex]\( 72^\circ \)[/tex] and angle K measures \( 36^\circ \), the sum of angles J and K is [tex]\( 72^\circ + 36^\circ = 108^\circ \).[/tex]
3. Since the triangle is isosceles, the base angles (angles J and K) are congruent, so each measures half of the sum of angles J and K, which is [tex]\( \frac{108^\circ}{2} = 54^\circ \).[/tex]
4. Since angle L is the remaining angle in the triangle and the sum of the angles in a triangle is \( 180^\circ \), we subtract the sum of angles J and K from [tex]\( 180^\circ \)[/tex] to find the measure of angle L: [tex]\( 180^\circ - 108^\circ = 72^\circ \)[/tex].
5. Therefore, angle L measures [tex]\( 72^\circ \)[/tex].

Jacqueline drove 72 km on 6 L of gasoline. Which of the following equations can be used to find how far she can travel on a full tank of 50 L?
Jacqueline's car gets 12 km per liter of gasoline. Therefore, on a full 50 L tank, she would be able to drive 600 km.
Explanation:To solve this problem, we need to determine Jacqueline's rate of distance traveled per liter of fuel consumed, then scale this up to find out how far she could theoretically drive on a full tank of 50 liters of gasoline. Jacqueline drove 72 km on 6 L of gasoline, so she is driving at a rate of 72 km / 6 L = 12 km/L.
To find out how far she could drive on a full tank of 50 L of gasoline, we can multiply this rate (12 km/L) by the total volume of the tank. This gives us 12 km/L * 50 L = 600 km.
So using this rate, Jacqueline would be able to drive 600 km on a full 50 L tank of gasoline, assuming that her car’s fuel efficiency stays consistent.

Jacqueline can travel 600 km on a full tank of 50 L.
First, set up the proportion based on the given information,
Distance travelled / Gasoline used = Unknown distance / Full tank
This gives us:
72 km / 6 L = X km / 50 L
Now, solve for X by cross-multiplying and then dividing,
72 km * 50 L = 6 L * X km
3600 kmL = 6X kmL
3600 kmL / 6 = X km
X = 600 km
Therefore, Jacqueline can travel 600 km on a full tank of 50 L of gasoline.

The Baldwin family walked four over five of a mile in four over nine of an hour. What is their unit rate in miles per hour?
A.) four-ninths over four-fifths equals four over nine miles per hour
B.) four-fifths over four-ninths equals one and four-fifths miles per hour
C.) four-ninths over four-fifths equals one and four-fifths miles per hour
D.) four-fifths over four-ninths equals four over nine miles per hour
Answer:
B.
Step-by-step explanation:
4/5 go over 4/9 because you are trying to find the unit rate of miles per hour. Since 4/5 is the mile, put that over 4/9. Then, simply divide the two fractions. Which is 1 over 4/5.

Misha used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below: Color of Marble Number of Times Rolled Blue 20 Green 18 Yellow 12 Heads Tails 28 22 Using Misha's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
To solve this problem, let us first remember that probability is:
Probability = number of successful events / number of total events
Now, let us first calculate the probability of getting a blue marble. There are 20 blue marbles out of 50 total marbles, therefore the probability is:
P (blue marble) = 20 / 50 = 0.4
Next, let us calculate for the probability of landing tails up. There are 22 tails success out of 50 times the coin was tossed, therefore the probability is:
P (tails) = 22 / 50 = 0.44
Finally, since we want to find the Probability of getting blue and Probability of landing tails, we multiply the two:
P (blue and tails) = 0.4 * 0.44
P (blue and tails) = 0.176 (ANSWER)
Now if the choices are in fraction:
P (blue and tails) = (20 / 50) (22 / 50) = 440 / 2500
Answer:
The answer is 440/2500
