Answer:
x = 32
y = 16
Step-by-step explanation:
As can be seen in the picture (replace x by z), if the long side length is z√3, the other sides are 2z and z, respectively. (Using z to avoid confusion with your pic).
So z = 16, so x=2z=32, y=x=16
if 24 students took a test and 18 passed how much percent passed?
Answer:
75%

Describe fully the single transformation that maps triangle a onto triangle b
Answer:
reflection of Δa about y=2 results in Δb
Step-by-step explanation:
The single transformation that maps triangle a onto triangle b is: Reflection about y=2
Triangle A should be reflected about y=2 to map it onto Triangle B.
Here, from the given figure we get,
Coordinates of the vertices of triangle (A) are A(1, 3), B(2, 3) and C(1, 5)
After transformation of triangle A, coordinates of the vertices A', B' and C' of the image triangle (B) are,
A'(1, 1), B'(2, 1) and C'(1, -1)
Lets choose point A to find the rule of transformation,
A(1, 3) → A'(1, 1)
Rule → (x, y) → (x, 2 - (y - 2)) or (x, y) → (x, 4 - y)
It shows triangle (A) has been reflected across a line y = 2.
Therefore, Triangle A should be reflected about y=2 to map it onto Triangle B.

Answer:
D
Step-by-step explanation:
A. The domain of this function is infinite, since x can be any number.
B. To find the y intercept, you need to set x to 0. 7^x will become 1, and 6*1=6, so the y intercept is (0,6).
C. This function is not always decreasing. For instance, when x is positive, it exponenentially increases.
D. As I said before, the y intercept of the function is (0,6), meaning that this statement is correct.
Hope this helps!
2b) A farmer is building a pen inside a barn. The pen will be in the shape of a right triangle.
The farmer has 14 feet of barn wall to use for one side of the pen and wants another side of the pen to be 15 feet long.
a. To the nearest tenth of a foot, find all possible lengths for the third side of the triangle.
b. The farmer wants the area of the pen to be as large as possible. What length should he choose for the third side? Justify your answer.
Answer:
For the pen to be as large as possible, the length the farmer should choose for the third side should be 20.52 feet
Step-by-step explanation:
The length of one side of the right triangle = 14 feet
The length of the other side = 15 feet
Therefore, the length of the third side can be one of the following side lengths;
[tex]S_{3,1} = \sqrt{14^2 + 15^2} = \sqrt{421} = 20.52 \ feet[/tex]
[tex]S_{3,2} = \sqrt{15^2 - 14^2} = \sqrt{29} = 5.39 \ feet[/tex]
The possible lengths of the third side of the triangle are;
Third side = 20.52 feet and
Third side = 5.39 feet
b. For the area of the pen to be as large as possible, we have;
With third side = 20.52 feet, area of the pen = 0.5 × 15 × 14 = 105 ft²
With third side = 5.39 feet, area of the pen = 0.5 × 5.39 × 14 = 37.7 ft²
Therefore, for the pen to be as large as possible, the farmer should choose 20.52 feet as he third side.
Answer:
a. c ≈ 20.5 ft (first possibility)
b ≈ 5.4 ft(other possibility)
b. The farmer should choose the side that has 20.5 ft for the third side because it provide more larger area as needed by the farmer.
Step-by-step explanation:
The pen the farmer wants to build is a right angle triangle. one side of the triangle is 14 ft while another side is 15 ft.
A right angle triangle has opposite side, adjacent side and an hypotenuse which is the longest side.
a. To the nearest tenth of a foot, find all possible lengths for the third side of the triangle.
Pythagoras theorem can be used to solve any sides of the triangle when given 2 sides.
We are not told which side is the hypotenuse or the adjacent or the opposites side. Therefore , the possible length for the third side can be computed using Pythagoras theorem.
c² = a² + b²
c = hypotenuse
while a and b can be any of opposite or adjacent sides. The first possible length can be when both sides are the legs of the triangle (no hypotenuse)
c² = 14² + 15²
c² = 196 + 225
c² = 421
c= √421
c = 20.5182845287
c ≈ 20.5 ft (first possibility)
The other possibility of the third side is when the hypotenuse is Known and one other side(either adjacent or opposite). We can use only 15 since it should be the longest side.
c² = a² + b²
c² - a² = b²
15² - 14² = b²
225 - 196 = b²
b² = 29
b = √29
b = 5.38516480713
b ≈ 5.4 ft(other possibility)
b. The farmer wants the area of the pen to be as large as possible. What length should he choose for the third side? Justify your answer.
The two scenarios are as follows
First area
area = 1/2 × base × height
area = 1/2 × 14 × 15 = 210/2 = 105 ft²
Second area
area = 1/2 × base × height
area = 1/2 × 5.4 × 14 = 75.6/2 = 37.8 ft²
The farmer should choose the side that has 20.5 ft for the third side because it provide more larger area as needed by the farmer.

Karla empleo 6kg de manzanas para elaborar 90 bocadillos mas ¿Cuantos Kilogramos de manzanas necesitara? ¿ cuantos bocadillos podria hacer con 12kg de manzanas?
Answer:
12kg apple will make 189 more sandwiches
Step-by-step explanation:
Here, we are told that 6kg of apple was used to make 90 more sandwiches and we need to know the number of sandwiches that can be made from 12kg of apples.
Now;
6kg made 90 sandwiches
12kg will make x sandwiches
To get x, we simply cross multiply
6 * x = 12 * 90
x = (12 * 90)/6
x = 2 * 90
x = 180 sandwiches

Answer:
2x=125-10. Answer is 57.5
Step-by-step explanation:
It was asking for the length of the missing sides, and both of them are the same so its 2x= something. the other 2 sides are the same length (5) so that's where the 10 comes from. The 125 is the total perimeter. So, first you subtract 10 from 125 and you get 115. And then you divide 2 on both sides and you get x=57.5

How many quarts of a 50% solution of acid must be added to 20 quarts of a 20% solution of acid to obtain a mixture containing a 40% solution of acid? Answer: quarts
Answer:
Step-by-step explanation:
How many quarts of a 50% solution of acid must be added to 20 quarts of a 20% solution of acid to obtain a mixture containing a 40% solution of acid? Answer: quarts
let x = amount of the 50% solution
A typical mixture equation using the decimal equivalent to
0.50x +0 .20(20) =0 .40(x+20)
0.50x + 4 = 0.40x + 8
0.50x - 0.40x = 8 - 4
0.10x = 4
x = 4/0.1
x = 40 qts of 50% solution
Hence 40 quarts of 50% solution must be added.Answer:
40 quarts I checked in RSM portal

find the value of "y" log(4y+1)=log(y-7)-2log2
Answer:
y = -8/15
Step-by-step explanation:
log (4y + 1) = log (y - 7) - 2log2
log (4y + 1) = log (y - 7) - log2² (power law)
log (4y + 1) = log [(y - 7)/4]
4y + 1 = (y - 7)/4 (remove log)
4(4y + 1) = y - 7
16y - y = -8
15y = -8
y = -8/15
19. A bakery sold three kinds of muffins on Monday. The ratio of cranberry to blueberry muffins sold was 2/3 . The ratio of blueberry to cinnamon muffins sold was 1. If 60 blueberry muffins were sold on Monday, how 4/1 many more cranberry muffins than cinnamon muffins did the bakery sell? *
Answer:
25
Step-by-step explanation:
The ratio of cranberry to blueberry muffins sold was 2/3.
This means that for every 3 blueberry muffins, 2 cranberry muffins were sold.
The ratio of blueberry to cinnamon muffins sold was 4/1.
This means that for every cinnamon muffin, 4 blueberry muffins were sold.
In other words, the ratio of cinnamon muffins to blueberry was 1/4.
60 blueberry muffins were sold on Monday.
This means that the number of cranberry muffins sold was:
2/3 * 60 = 40 cranberry muffins
This also means that the number of cinnamon muffins sold was:
1/4 * 60 = 15 cinnamon muffins
To find how many more cranberry muffins were sold than cinnamon muffins:
40 - 15 = 25 muffins
25 more cranberry muffins were sold.

<OLD>
Answer:
4.9 ≤ l ≤ 5.1
Step-by-step explanation:
'I' represents the length of the acceptable length for the board in feet.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
here,
A carpenter is cutting a 2 by 4 framing for a roof. The length needs to be 5 feet.
He allows a 0.1-foot possible variation for the length of the cut. where variation becomes,
5 - 0.1 ≤ I ≤ 5 + 0.1
4.9 ≤ I ≤ 5.1
Thus, 'I' represents the length of the acceptable length for the board in feet.

3. 2x + y = 21.
Step-by-step explanation:
3. The diagonals of a rhombus are perpendicular and bisect each other.
So the slope of line AC = -1/m
= -1 / 1/2 = -2.
AC has coordinates (5, 11) so using the point-slope form of a line:
y - 11 = -2(x - 5)
y = -2x + 10 + 11
2x + y = 21.
5. Line L:
x + 2y = 12
2y = -x + 12
y = -1/2x + 6
The slope is -1/2 so the slope m of M is -1 / -1/2 = 2.
