M is the midpoint of PQ.
PM = 5x + 8 and PQ = 76, find x.
(2 Points)
Enter your answer
Answer: x=6
Step-by-step explanation:
Just think about how the problem is half
The value of x is 6.
Here,
M is the midpoint of PQ.
PM = 5 x + 6
PQ = 76
What is midpoint of line?
The midpoint is the middle point of a line segment. It is equidistant from both end points.
Now,
M is the midpoint of PQ.
Hence, PM = MQ
And, PQ = PM + MQ
⇒ PQ = 2 PM
⇒ 76 = 2 (5x + 8)
⇒ 38 = 5x + 8
⇒ 5x = 30
⇒ x = 6
Hence , The value of x is 6.

<3Twice Use what you have learned to compare circles by their characteristics. 1. Draw each circle. A. Radius length of 3 centimeters b. Diameter length of 3 centimeters 2. Describe the similarities and differences between your two circles. 3. Describe the relationship between the circumferences of the two circles. 4. Describe the circumference-to-diameter ratio of all circles.
Answer:
1. a. Please find attached, the diagram for the first circle with radius = 3 cm
b. Please find attached, the diagram for the second circle with diameter = 3 cm
2. The similarities are;
a) Both circles can be described by a point and a radius or a diameter
The differences are;
a) The length of the radiuses are different for the two circles (3 cm and 1.5 cm)
b) The circumferences of the two circles are different
c) The area covered by the two circles are different
3. The circumference of the circle with radius equal to 3 cm is larger than the circumference of the circle with diameter equal to 3 cm
4. The circumference to diameter ratio of the circle with radius = 3 cm is π
The circumference to diameter ratio of the circle with diameter = 3 cm is π
Both circles have equal circumference to diameter ratio given that the circumference = π × The diameter
Step-by-step explanation:
1. a. The radius length of the first circle = 3 cm
The diagram for the first circle with radius 3 cm is attached
b. The diameter length of the second circle = 3 cm
The diagram for the second circle with diameter 3 cm is attached
2. The similarities are;
a) Both circles can be described by a point and a radius or a diameter
The differences are;
a) The length of the radiuses are different for the two circles (3 cm and 1.5 cm)
b) The circumferences of the two circles are different
c) The area covered by the two circles are different
3. The circumference of the circle with radius equal to 3 cm is 2 × π × 3 = 6·π cm
The circumference of the circle with diameter equal to 3 cm is π × 3 = 3·π cm
Therefore, the circumference of the circle with radius equal to 3 cm is larger than the circumference of the circle with diameter equal to 3 cm
4. The circumference to diameter ratio of the circle with radius = 3 cm is 6·π cm/(2 × 3 cm) = π
The circumference to diameter ratio of the circle with diameter = 3 cm is 3·π cm/(3 cm) = π.
Both circles have equal circumference to diameter ratio given that the circumference = π × The diameter.

What is the remainder when a^3 - 4 is divided by a+2?
a)0
b)-6
c)-2
d)-12
Answer:
The remainder is -12. Choice d)
Step-by-step explanation:
The Remainder Theorem
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial
[tex]P(a)= a^3 - 4[/tex]
To evaluate the remainder when P is divided by a+2, we only have to find P(-2):
[tex]P(-2)= (-2)^3 - 4[/tex]
[tex]P(-2)= -8 - 4=-12[/tex]
The remainder is -12. Choice d)

How many degrees does the minute hand of a clock travel in 1 minute? What angle does an hour hand travel in 1 min?
Answer:
6° and acute angle
you watch the clock or find a clock, in right angle there 90° or 3 o'clock, if you want to understand it, try to count the the minute from 12 to 3 in the clock, if you count it then you see the are there is 15 minutes, then the 90° divide the number of minute which is 15, the answer is 6°. and then the answer of the next question is acute angle it is because the hour hand of the clock travels in 1 minute, it means every 1minute there are 6°, and 6° is less than 90° that why it's acute angle.
