We can see two main triangles from the image which are;
ΔVWX and ΔYZX
The two triangles are similar and using ratio of similar triangles, we have;
VW/WX = YZ/ZX
Plugging in the relevant values gives;
10/6 = YZ/3
Cross multiply to get;
YZ = 3 * 10/6
YZ = 5 miles
Since speed is given as 3.2 miles per hour and we know that formula for time is;
time = distance * speed
Then; time = 5 * 3.2
time = 16 hours

Answer:
Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]3x -2 < 4[/tex] and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.
[tex]3x -2 < 4[/tex]
Adding 2 on both sides
[tex]3x -2+2 < 4+2\\3x < 6[/tex]
Now, we will divide 3 on both sides
[tex]\frac{3x}{3}<\frac{6}{3}\\x<2[/tex]
So, we get x < 2
Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]

One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. How many more calories from fat are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels?
Answer: 50 calories
Step-by-step explanation:
One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:
= 90/150 = 3/5
One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:
= 12/120 = 1/10
The fat that are provided by a 100 calorie serving of the microwave popcorn would be:
= 3/5 × 100
= 60
The fat that are provided by a 100-calorie serving of the pretzels would be:
= 1/10 × 100 = 10
The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:
= 60 - 10
= 50 calories

Em de terminado dia, sofia voltava de sua casa 2h30min acima do horario que sua mãe determinou para sua própria segurança . Sabendo que o horário que sua mãe determinou foi as 20h, qual horário que ela estava voltando?
Responda:
22:30
Explicação passo a passo:
Dado que :
Hora definida pela mãe = 20h00
Número de horas além do tempo definido = 2 horas e 30 minutos
Hora em que ela voltou para casa:
(tempo definido pela mãe + número de horas além do tempo definido)
(20h + 2 horas e 30 minutos) = 22h30
Which of the following statements is NOT a property of parallelograms?

4. Consecutive angles are supplementary.
Answer:
3
Step-by-step explanation:
took the test
also parallelograms are the slanted ones so they dont always have the 90 degree angles.
The non-necessary property of a parallelogram is All angles are right angles.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
GIven that, what can not be a property of parallelograms
All the properties given in the option are correct for a parallelogram, but the option saying all angles should be a right angle, is not a correct one, because it is not necessary for a parallelogram to have all four angles 90°, it is only in two types of special parallelograms, that are rectangles and squares.
Hence, the non-necessary property of a parallelogram is All angles are right angles.

Which statements about circle O are true? Select three options. The radius of circle O is 13. The diameter of circle O is 34. LP is a diameter of circle O. ∠LMP intercepts a semicircle. The measure of arc LP is 90°.
Answer:
The radius of circle O is 13
LP is a diameter of circle O.
∠LMP intercepts a semicircle.
Step-by-step explanation:
The missing image is attached in the diagram below.
From the diagram;
we can determine the length LP by using the Pythagoras theorem.
i.e.
hypotenuse² = opposite² + adjacent²
LP² = ML² + MP²
LP² = 24² + 10²
LP² = 576 + 100
LP = [tex]\sqrt{676}[/tex]
LP = 26
Since line LP cuts the circle into two equal halves, we can say the line LP is the diameter of circle O.
if the diameter (LP) = 26
Then, the radius r = 26/2 = 13
The radius of circle O is 13.
Similarly, the arc LMP is 180° (∵ inscribed angle is 1/2 the measure of central angle), and LMP is 180°, then ∠LMP intercepts a semicircle.
Answer: A) The radius of circle O is 13.
C) LP is a diameter of circle O.
D) ∠LMP intercepts a semicircle.
