What is the volume of a figure with that is 2 inches wide, 7 inches tall and 9 inches
Pls help
Answer:
126
Step-by-step explanation:
What is the volume of a figure with that is 2 inches wide, 7 inches tall and 9 inchesn = Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
2x7x9 = 126
Answer:
126 inches³
Step-by-step explanation:
The volume of a figure is l×w×h.
So,
9 × 2 × 7 = 126

Can someone please help me?
Answer:
Question 1: The answer is "He could ask each person in his class who is the tallest person in the class."
Question 2: The mode is 56.
Step-by-step explanation:
Explanation 1: A statistical question is a question that can be answered by collecting data that varies. For example, “How old am I?" is not a statistical question, but “How old are the students in my school?” is a statistical question. Therefore, when we look at the options, the second option is the best.
Explanation 2: To find the mode we have to find which number is most frequent through out the set. When we look at the numbers, there are 3 numbers that have 56. Therefore, 56 is the mode.

Point P lies on circle C, x^2+y^2=36. There are two unique tangents to circle D, x^2+y^2=18 that pass through point p. What is the measure of the angle between the two tangent lines?
Answer:
90°Step-by-step explanation:
Refer to attached
Red circle is C with radius 6 and green circle is D with radius √18.
PM and PN are tangents to circle D.
M and N are right angles as tangents are perpendicular to radius.
We need to find the measure of ∠MPN.
We'll work out this angle using trigonometry:
OM / OP = sin (∠MPO) sin (∠MPO) = √18/6 = √2/2m∠MPO = arcsin ( √2/2) = 45°∠NPO is same as ∠MPO, therefore:
m∠MPN = 45°*2 = 90°If a pyramid prism has a height of 12 ft and a square base with side = 10

Solve 169x^2-42.25=0 by using square roots?
NEED HELP!!!
Answer:
x = 1/2 , x = -1/2
Step-by-step explanation:
Given equation;
169x² - 42.25
Find:
Solution of equation using square root
Computation:
169x² - 42.25
We know that 13² = 169 and 6.5² = 42.25
So,
[13x]² - [6.5]²
a² - b² = (a + b)(a - b)
So,
[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]
So,
13x + 6.5 = 0 , 13x - 6.5 = 0
x = 6.5 / 13 , x = -6.5 / 13
x = 1/2 , x = -1/2

A die used in a certain board game has eight faces, of which 3 are red, 3 are yellow, and 2 are blue. Each face is equally likely to land faceup when the die is tossed. In the game, a player tosses the die until blue lands faceup, and the number of tosses before blue lands faceup is counted. For example, a player who tosses the sequence shown in the following table has tossed the die 3 times before blue lands faceup. What is the probability that a player will toss the die at least 2 times before blue lands faceup? A 0.1406 B 0.4219 C 0.4375 D 0.5625 E 0.5781
Answer: 0.5625
Step-by-step explanation:
Using the binomial distribution, it is found that the probability that a player will toss the die at least 2 times before blue lands face up is:
D 0.5625
For each toss, there are only two possible outcomes, either blue lands face up, or it does not. The probability of blue landing face up on a toss is independent of any other toss, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.In this problem:
2 out of the 8 faces are blue, hence [tex]p = \frac{2}{8} = 0.25[/tex]The probability that a player will toss the die at least 2 times before blue lands face up is P(X = 0) when n = 2, hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{2,0}.(0.25)^{0}.(0.75)^{2} = 0.5625[/tex]
Hence, option D is correct.

B. M - J = 6
Step-by-step explanation:
Mike won 6 more games than Jeanie
so J + 6 = M
Subtract J from both sides of the equation
J - J + 6 = M - J
Simplify
6 = M - J

What is the value of u? (pls help and no links)
Answer:
I think 44 degrees
Step-by-step explanation:
73-29=44
Answer:
44
Step-by-step explanation:
The value of u, combined with the angle directly next to it (with the measurement of 29°), is a vertical angle to the opposite given angle (73°).
Note that, by the definition of vertical angles, angles directly next and opposite of each other have the same measurement. Set the equation:
u + 29 = 73
Isolate the variable, u. Note the equal sign, what you do to one side, you do to the other. Subtract 29 from both sides:
u + 29 (-29) = 73 (-29)
u = 73 - 29
u = 44
44° is your answer for u.
