238 divided by 11 equals 21 with a remainder of 7.
To divide 238 by 11 using long division, we follow these steps:
Set up the division: Write 238 as the dividend and 11 as the divisor. Place the dividend inside the long division symbol and the divisor outside of it.
Begin dividing: Divide the first digit of the dividend (2) by the divisor (11). The quotient is 0 since 2 is less than 11.
Bring down the next digit of the dividend (3) and place it after the 0. We now have 23.
Divide 23 by 11. The quotient is 2 as 11 goes into 23 two times.
Multiply the divisor (11) by the quotient (2) and subtract the result from 23:
23 - (11 x 2) = 23 - 22 = 1
Bring down the next digit of the dividend (8). We now have 18.
Divide 18 by 11. The quotient is 1 as 11 goes into 18 one time.
Multiply the divisor (11) by the quotient (1) and subtract the result from 18:
18 - (11 x 1) = 18 - 11 = 7
There is no more digit to bring down, so we have completed the division. The final remainder is 7.

The figure shows a person estimating the height of a tree by looking at the
top of the tree with a mirror. Assuming that both the person and the tree form
right angles with the ground, which of the following proportions can be used
to estimate the height of the tree?
Answer:
The proportion that can be used to estimate the height of the tree is option;
A. [tex]\dfrac{h}{12} = \dfrac{6}{5}[/tex]
Step-by-step explanation:
The given parameters in the question are;
The medium through which the person looks at the top of the tree = A mirror
The angle formed by the person and the tree with the ground = Right angles = 90°
The distance of the person from the mirror, d₁ = 5 ft.
The height of the person, h₁ = 6 ft.
The distance of the tree from the mirror, d₂ = 12 ft.
The angle formed by the incident light from the tree on the mirror, θ₁ = The angle of the reflected light from the mirror to the person, θ₂
Let 'A', 'B', 'M', 'T', and 'R' represent the location of the point at the top of the person's head, the location of the point at the person's feet, the location of the mirror, the location of the top of the tree and the location of the root collar of the tree, we have;
TR in ΔMRT = The height of the tree = h, and right triangles ΔABM and ΔMRT are similar
The corresponding legs are;
The height of the person and the height of the tree, which are AB = 6 ft. and TR = h, respectively
The distances of the person and the tree from the mirror, which are BM = 5 ft. and MR = 12 ft. respectively
∴ The angle formed by the incident light from the tree on the mirror, θ₁ = ∠TMR
The angle of the reflected light from the mirror to the person, θ₂ = ∠AMB
Given that θ₁ = θ₂, we have;
tan(θ₁) = tan(θ₂)
∴ tan(∠TMR) = tan(∠AMB)
[tex]tan\angle X = \dfrac{Opposite \ leg \ length \ to \ reference \ angle}{Adjacent \ leg \ length \ to \ reference \ angle}[/tex]
[tex]tan(\angle TMR) = \dfrac{TR}{MR} = \dfrac{h}{12}[/tex]
[tex]tan(\angle AMB) = \dfrac{AB}{BM} = \dfrac{6}{5}[/tex]
From tan(∠TMR) = tan(∠AMB), we have;
[tex]\dfrac{h}{12} = \dfrac{6}{5}[/tex]
[tex]\therefore h = \dfrac{6 \, ft.}{5 \, ft.} \times 12 \, ft. = 14.4 \, ft.[/tex]
The height of the tree, h = 14.4 ft.
Therefore, from the proportion [tex]\dfrac{h}{12} = \dfrac{6}{5}[/tex] the height of the tree can be estimated.

Tell whether the side lengths form a Pythagorean triple.
o yes
no
Answer:
x = √72 and yes, it forms a Pythagorean triple
Step-by-step explanation:
a^2 + b^2 = c^2,
3 is a, x is b, anf 9 is c
3^2 + x^2 = 9^2
9 + x^2 = 81
Subtract 9 from both sides
x^2 = 72
x = √72

Answer:
X = 9.4
Step-by-step explanation:
Pythagorean Theorem:
Formula: a² + b² = c²
9 x 9 = 81 3 x 3 = 9 81 + 9 = 90 √90 = 9.48 (Rounded 9.5)- A Pythagorean triple consists of any three positive integers.

Eight people go to a movie. Adult tickets cost $15 and children's tickets cost $8
The total cost was $85. Write an equation and use it to help you find the numbers of
adults and children who went to the movie.
Answer: number of adults = 3, number of children = 5
Step-by-step explanation:
let the number of adults be x, and the number of children be y.
x + y = 8 , 15x + 8y = 85
1st equation x 8 = 8x + 8y = 64
[tex]8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3[/tex]
substitute x=3

Answer:
The binomial 14[tex]x^{2}[/tex] - 35x can be factored as 7x(2x+5)

Please use the following scenario for this question and the following 4 questions. The national academy of sciences reported in a 1997 study that 40% of research in mathematics is published by US authors. The math chairperson of a university wishes to test the claim that this percentage is no longer 40%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 130 recent articles published by reputable math research journals and finds that 62 of these articles have US authors. Does this evidence support the math chairperson's claim that the percentage is no longer 40%
Answer:
The evidence does not support the math chairperson's claim that the percentage is no longer 40%
Step-by-step explanation:
The known population percentage of research in mathematics published by US authors = 40%
The proportion, p = 0.40
Therefore, q = 1 - p = 1 - 0.4 = 0.6
The number of articles in the sample = 130
The number of articles by US authors in the sample = 62
Therefore, the proportion of US authors in the sample, [tex]\hat p[/tex] = (62/130) × 100 =
[tex]0.4\overline{769230}[/tex]
∴ The percentage of US authors in the sample ≈ 47.7%
The null hypothesis, H₀; p = 0.4
The alternative hypothesis, Hₐ; p ≠ 0.4
The z-test is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p\cdot q}{n}}}[/tex]
[tex]z=\dfrac{0.477-0.40}{\sqrt{\dfrac{0.4\times 0.6}{130}}} \approx 1.792[/tex]
The p-value P(Z > 1.79) = 2 × (1 - 0.96327) = 0.07346
Therefore, given that the p-value is larger than 0.05 there is significant evidence in favor of the null hypothesis and we reject the alternative hypothesis
Therefore, also, there is not enough statistical evidence to support the math chairperson's claim that the percentage is no longer 40%.

If you place a 29-foot ladder against the top of a building and the bottom of the ladder is 24 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
16.3
Step-by-step explanation:
The height of the building to the nearest tenth is 16. 3 ft
The situation forms a right triangle.
Properties of a right triangle:One of its angles is 90 degreesThe sides can can be found using Pythagoras theorem.The length of the ladder is the hypotenuse of the triangle formed.
The distance from the foot of the ladder to the bottom of the building is the adjacent sides.
Therefore,
c² = a² + b²
where
c = hypotenuse
a and b are the other two legs.
b² = 29² - 24²
b² = 841 - 576
b = √265
b = 16.2788205961
b = 16.3 ft

¿Cuántas cifras tiene el número quinientos cincuenta y cinco mil? Respuesta: ____________ CM DM UM C D U NÚM. DE CIFRAS
Answer:
6 cifras.
Step-by-step explanation:
Siempre que tengamos un numero que termina en "mil", entonces la primer parte la escribimos y luego ira una coma:
por ejemplo, en "ciento once mil trecientos catorce"
lo separamos en:
"ciento once mil" y "trecientos catorce"
y lo escribimos como:
"ciento once" , "trecientos catorce"
111,314
Ahora que definimos esto, vamos a nuestro problema.
Tenemos el numero "quinientos cincuenta y cinco mil"
El cual podemos escribir como:
555,000
Ahora simplemente podemos contar las cifras, tenemos 6.
las cuales son:
Cientos de miles = CM = 5
Decenas de miles = DM = 5
Un miles = UM = 5
Cientos = C = 0
Decenas = D = 0
Unidades = U = 0
Colton sold a total of 28 tee shirts and sweatshirts as a fundraiser for his football team. If tee shirts cost 12 dollars each and sweatshirts cost 20 dollars each and he raised a total of 424 dollars how many tee shirts did he sell?
Answer:
11 sweatshirts and 17 t shirts
Step-by-step explanation:
[tex]t + s = 28\\12t = 20s = 424[/tex]
Step one: cancel out one variable. In this one, t.
[tex]-12(t + s = 28)\\-12t -12s =-336[/tex]
Now that we have that, subtract that from the other expression.
[tex]12t + 20s = 424\\-12t -12s = 336[/tex]
You should get:
[tex]8s = 88\\ s = 11[/tex]
Plug s in any expression
[tex]t + 11 = 28[/tex]
You should know where to go from there, I'm lazy :p
Then t = 17
GOod Luck!!!!
