One number is three times another number. If the sum of the numbers is 36, determine the two numbers.
Step-by-step explanation:
A=3B
A+B=36
3B+B=36
4B=36
B=36/4
Step-by-step explanation:
let x represent the smaller number
3x is the second number
x+3x=36
4x=36
4x/4=36/4
x=9
the second number is 3(9)
=27
A relative frequency table is made from data in a frequency table. Relative Frequency Table: A 4-column table with 3 rows. The first column has no label with entries likes S, T, total. The second column is labeled U with entries 26%, 21%, 47%. The third column is labeled V with entries 42%, k, 53%. The fourth column is labeled total with entries 68%, 32%, 100%. What is the value of k in the relative frequency table? Round the answer to the nearest percent.
Answer:
Hey There. ☆~<___`£《》£`____>~☆ The correct answer is: 33% okay if you don't understand this. Just tell me Okay. k=11 And, let me know if you don't understand how I got this. So, I'm gonna write it out
U V total
S 26 42 68
T 21 k 32
Total 47 53 100
So, you want to look at the column and row labeled total, this is the key. for the row total, it sums up everything in the column above it. so for the u column, the total value is 47 while the two values above it are 26 and 21. These two values sum to 47. This is the same for all other columns, and you can use the same reasoning with the total column as well summing rows.
This gives you two ways to solve for k. either 21 + k = 32 or 42 + k = 53. Either way gets you the answer k = 11

In a birthday party, a cake was cut into 30 equal sizes pieces. At the end of the party, 8 pieces were left. What was the percentage of cake consumped?
Answer:
73 1/3 %
Step-by-step explanation:
8 pieces were left
30-8 = 22 so 22 were consumed
22/30 is the percent consumed
.7333333
73.333333%
We know .333333333 is 1/3

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 ¾ feet long.
Each president's picture is 6 inches wide.
4. How would your answer change if the pictures were 10 inches wide? Explain.
Answer:
The number of pictures changes from 8 to 4.
Step-by-step explanation:
I assume the first question was the number of pictures that could be placed when the pictures are 6 inches wide.
Let's first answer the first question.
Wall length: 9.75 ft
Window: 5¾ ft = 5.75 ft
Available wall space for pictures:
9.75 ft - 5.75 ft = 4 ft
Now we convert 4 ft to inches.
1 ft = 12 inches
4 ft = 4 * 12 inches = 48 inches
There is 48 inches of wall space to place pictures that measure 6 inches each.
48 inches / 6 inches = 8
Originally, there is room for 8 pictures.
Question 4.
Each picture is 10 inches wide.
There is still 48 inches of wall space for the pictures.
48 inches / 10 inches = 4.8
There is room for 4.8 pictures. Since Mr. Hamilton will place only whole picture, he can only place 4 pictures now.
Answer: The number of pictures changes from 8 to 4.

Answer:
see explanation
Step-by-step explanation:
Corresponding angles within the similar figures are congruent, thus
x = ∠ A = 52°
h = 7 × 1.5 = 10.5 cm
From B to A then divide by the scale factor, that is
w = 12 ÷ 1.5 = 8 cm

Find $a/b$ when $2\log{(a -2b)} = \log{a} + \log{b}$.
By some properties of logarithms, rewrite the equation as
[tex]2\log(a-2b) = \log(a) + \log(b) \\\\ \log(a-2b)^2 = \log(ab)[/tex]
so that
(a - 2b)² = ab
Expand the left side:
a ² - 4ab + 4b ² = ab
Rearrange terms to get a quadratic equation in a/b :
a ² - 5ab + 4b ² = 0
b must be greater than 0, otherwise log(b) doesn't exist, and the same goes for a. So we can divide by b ² to get
a ²/b ² - 5a/b + 4 = 0
Factorize and solve for a/b :
(a/b - 4) (a/b - 1) = 0
==> a/b = 4 or a/b = 1
However, if a/b = 1, then a = b makes a - 2b = -b. But we must have b > 0, so we omit the second solution and end up with
a/b = 4

solve the equation: csc(4x)-2=0
Step-by-step explanation:
csc(4x) − 2 = 0
csc(4x) = 2
sin(4x) = 1/2
In radians:
4x = π/6 + 2kπ, 5π/6 + 2kπ
x = π/24 + kπ/2, 5π/24 + kπ/2
In degrees:
4x = 30° + 360°k, 150° + 360°k
x = 7.5° + 90°k, 37.5° + 90°k

What would the equation, slope, and y-intercept be for this?
Answer:
y=-4x+1
Step-by-step explanation:
Equation: y=mx+b where m = slope and b= y intercept
TO find the slope, find the change in y over the change in x , or just to rise over run
From (-1,5) to (0,1), the y changes by -4 and the x changes by 1.
So the slope will be -4
To find the y intercept, find the point at which the line crosses the y-axis.
In this case, it is at (0, 1), so your y intercept will be 1
Plug all this info back into the equation and you get y=-4x+1
The y-intercept is 1 and that’s it sorry I can’t answer the rest.

please help :) Which is a component of pseudoscience, but not science? A) explanations B) beliefs C) facts D) processes
The correct answer is B) Beliefs
Explanation:
Pseudoscience differs from science because this is based on personal beliefs or non-proven statements. For example, disciplines such as Astrology or Numerology are considered pseudoscience because these cannot be proven scientifically, are not based in facts or reality, and in general, do not follow the standards of science. This means one component of pseudoscience is that this is based on personal beliefs as pseudosciences do not follow the scientific method but this does not occur in science.

Step-by-step explanation:
Recall that the product of the imaginary unit i by itself renders -1
Now proceed with the product of the two complex numbers using distributive property:

What is the standard equation of the circle?
Answer:
A is the answer
Step-by-step explanation:
the center of the circle is (-2,-1) so you're going to reverse their signs and insert that value in for x and y. the radius is 5, but the equation of a circle is
[tex]x ^{2} + {y}^{2} = {r}^{2} [/tex]
so you're going to square the radius, this making it 25.

Answer:
The answer would be 30% (although I don't see that as an answer).
Step-by-step explanation:
This is because when you multiply the denominator times a number that makes the denominator 100 and multiply that same number by the numerator you get the percentage of the sample you are looking at on the numerator.
15/50 = (15*2)/(50*2) = 30/100 = 30%

ANSWER QUICKLY PLZZZZZZ
Answer:
A= 17 B= 19
Step-by-step explanation:
Answer:
a) 17 cups water
b) 19 cups rice
Step-by-step explanation:
w = 1.5r + 0.5
For 11 cups of rice, r = 11.
w = 1.5(11) + 0.5
w = 16.5 + 0.5
w = 17
For 11 cups of rice, 17 cups of water are needed.
With 29 cups of water, w = 29.
29 = 1.5r + 0.5
28.5 = 1.5r
r = 19
With 29 cups of water, 19 cups of rice can be cooked.
for which prime p,p4+8 is also a prime number
Answer: p = 3.
Step-by-step explanation:
Ok, this must be:
p and p^4 + 8
ok, it may be useful to remember the first prime numbers:
2, 3, 5, 7, 11, 13...
So let's play with those and see what happens, this is solving a problem by brute force, this means that we will input those values in the equation p^4 + 8 and see if the result is also prime:
First, p = 2 is not the solution, because 2^4 + 8 = 24: not prime.
now let's try p = 3.
3^4 + 8 = 81 + 8 = 89, and 89 is a prime number, so the solution is p = 3.
