Which method can you use to prove these triangles congruent?
Answer: The HL Theorem.
Step-by-step explanation: We are given that the triangles have a congruent 90 degree angle and two congruent sides. This would indicate towards SAS but in this case, that doesn't work because the angle is not in between the two congruent sides. We know that the triangles are right, and that their hypotenuses are congruent and that one leg is congruent. Thus, the answer must be HL (hypotenuse & leg).
Answer:
The HL Theorem.
Step-by-step explanation:
Jeremy can stand on one leg for 3.8 minutes. Express that time in seconds.
Answer:
He can stand on one leg for 228 seconds.
Step-by-step explanation:

Translate the expression with rational exponents into a radical expression. Simplify if necessary.
(233) -
Look at the attached picture⤴
Hope it will help u..
Answer and Step-by-step explanation:
Whenever we have a fractional exponent, the numerator is always going to be the exponent, and the denominator will be the root.
Here, the numerator is 4, so we taking 343 to the fourth power. At the same time, since the denominator is 3, we are taking the cube root of 343. Thus, we can write the expression as:
[tex]\sqrt[3]{343^4}[/tex]
We want to simplify this. We need to complete both operations, but it doesn't matter what order we do them in. In fact, I would do the cube root first because that won't lead to gigantic numbers:
[tex](\sqrt[3]{343} )^4=7^4=2401[/tex]
Thus, the answer is, I believe, 2401 (although it's not in radical form, the problem asked for the simplified answer, which is this).

The probability that Babe Ruth hits a home run on any given at-bat is 0.12, and each at-bat is independent.
Part A: What is the probability that the next home run will be on his fifth at-bat? (5 points)
Part B: What is the expected number of at-bats until the next home run? (5 points)
Answer:
A) 0.072 = 7.2%
B) 8.3333 at-bats (8 to 9 at-bats)
Step-by-step explanation:
A)
If the chance of hitting a home run is 0.12, the chance of not hitting a home run is 1 - 0.12 = 0.88.
To find the probability of the next home run being in the fifth strike, we need the four other strikes to not be a home run, so the probability is:
P = (0.88)^4 * 0.12 = 0.072 = 7.2%
B)
To find the expected number of at-bats until the next home run, we just need to divide 100% by the probability of hitting a home run (0.12 = 12%):
100/12 = 8.3333
So the expected number is 8 to 9 at-bats

The sum of three consecutive integers is 9.
1. Determine the variable.
2. Identify key words and translate their meanings.
3. Write the multistep equation for the scenario.
Use the variable n to represent the first integer. Finish translating to identify the third integer.
1st integer: n
2nd integer: n + 1
3rd integer: n + _
To solve for three consecutive integers whose sum is 9, we can express the integers as n, n + 1, and n + 2. Using the equation n + (n + 1) + (n + 2) = 9, we find that n = 2. Therefore, the three consecutive integers are 2, 3, and 4.
Explanation:To solve for three consecutive integers whose sum is 9, we can start by expressing the integers in terms of a variable. Let's use the variable n to represent the first integer.
The second integer would then be n + 1, and the third integer would be n + 2.
The sum of these three integers is given as 9, so we can write the equation n + (n + 1) + (n + 2) = 9.
Simplifying the equation by combining like terms, we get 3n + 3 = 9. Subtracting 3 from both sides, we have 3n = 6. Finally, dividing both sides by 3, we find that n = 2.
Therefore, the three consecutive integers are 2, 3, and 4.

what is the nth term for 7,11,15,19
Answer:
[tex]a_{n}[/tex] = 4n + 3
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4, thus
[tex]a_{n}[/tex] = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

The diameter of a circle is 4 cm. Find its area to the nearest tenth.
Answer:
12.57cm²
Step-by-step explanation:
Hopefully this helps :)
The area of a circle with a diameter of 4 cm is found by using the formula A = πr² with the radius being half the diameter. After calculation, the area of the circle is 12.56 cm², which is rounded to 12.6 cm² to the nearest tenth.
The question requires us to find the area of a circle when given its diameter, which is 4 cm. To calculate the area, we will use the formula A = πr², but first, we need to determine the radius of the circle. As the radius is half the diameter, for our circle, the radius (r) is 2 cm (half of 4 cm). Substituting this value into the area formula:
A = πr²
= 3.14 × (2 cm)²
= 3.14 × 4 cm²
= 12.56 cm²
To provide the answer to the nearest tenth, we round the area to 12.6 cm². Therefore, the area of the circle is 12.6 cm²
when rounded to the nearest tenth.

4x-7y=15 and 5x-2y=12
Presumably we're being asked to solve the system.
4x - 7y = 15
5x - 2y = 12
We don't really have any common factors among the coefficients of x, or among the coefficients of y, so we can do the general thing. To eliminate y multiply the first equation by (typically the absolute value of) the coefficient of y in the second equation and vice verse, then add or subtract equations to eliminate.
First equation times 2:
8x - 14y = 30
Second equation times 7:
35x - 14y = 84
Subtract,
27x = 54
x = 54/27 = 2
2y = 5x - 12 = 10 - 12 = -2
y = -1
Answer: x=2, y = -1
Check:
4(2)-7(-1)=8+7=15, good
5(2) -2(-1) = 10 + 2 = 12, good

If you do enough of these 2x2 linear systems you can learn to just write down the answer. I usually remember the matrix inverse, but if you haven't gotten there you can just remember the pattern:
ax + by = c
dx + ey = f
has solutions
x = (ce-bf)/(ae-bd), y = (a f-cd)/(ae-bd)
4x - 7y = 15
5x - 2y = 12
has solutions
denom = ae-bd = 4(-2) - (-7)(5) = 27
x = (15(-2) - (-7)(12))/27 = (-30 + 84)/27 = 2
y = (4(12)-15(5))/27 = (48-75)/27 = -27/27 = -1
Answer:
Step-by-step explanation:
4x-7y=15
Add '-7y' to each side of the equation.
Add '2y' to each side of the equation.
5x + -2y + 2y = 12 + 2y
Combine like terms: -2y + 2y = 0
5x + 0 = 12 + 2y
5x = 12 + 2y
Divide each side by '5'.
x = 2.4 + 0.4y
Simplifying
x = 2.4 + 0.4y
4x + 7y + -7y = 15 + -7y
Combine like terms: 7y + -7y = 0
4x + 0 = 15 + -7y
4x = 15 + -7y

Circle A: center (2, 3) and radius 5. Circle B: center (-1, 4) and radius 10. Which of the
following is the necessary transformation (translation; dilation) from B to A to prove
that the two circles are similar?
Answer:
see explanation
Step-by-step explanation:
The centre of circle B requires to be coincident with centre of circle A
(- 1, 4 ) → (2, 3 )
That is a translation of < 3, - 1 >
This ensures that the circles are concentric ( have the same centre )
radius of B is 10 and radius of A is 5, thus
dilatation = [tex]\frac{5}{10}[/tex] = [tex]\frac{1}{2}[/tex]
