Answer:
[tex]y=10[/tex]
Step-by-step explanation:
We know that the sum of these two angles is 180 degrees. Why? Imagine if the horizontal line was perfectly horizontal. There would be two 90 degree angles, one at each intersection of the vertical lines. If the rotate the line, we haven't magically removed or added degrees, so we know it is still 180 degrees.
Hence, the equation is:
[tex]180=120+6y\\60=6y\\\bold{y=10}[/tex]

In a rectangle, the length is 5 more than three times the width. The perimeter is 250cm. Determine the length of each side.
Answer:
l = 95 cm
w = 30 cm
Step-by-step explanation:
w = width
5+3w = length
P = 2l + 2w
250 = 2(5+3w) + 2w
250 = 10 + 6w + 2w
240 = 8w
w = 30
5 + 3(30) = length
l = 95

In the right ABC above, the length of the side BC is 4.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
Given;
Side BA= [tex]\sqrt{11}[/tex]
Side AC= [tex]\sqrt{5}[/tex]
BC^2=BA^2+AC^2
BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2

A pile of cards contains red and blue
cards. The ratio of blue cards to red
cards is 5:7, and there are 15 blue
cards in the pile. What is the total
number of cards in the pile?
Answer:
There are 36 cards
Step-by-step explanation:
let blue be B and red be R
B:R =5:7
B/R = 5/7
there are 15 blue cards...
15/R = 5/7
make R subject of the formula...
R = (15×7)/5
R = 21
there are 21 red cards and 15 blue cards
Total number of cards = red cards + blue cards
= 21 + 15
= 36 cards
Suppose a normal distribution has a mean of 48 and a standard deviation of 5. What is the probability that a data value is between 48 and 52? Round your answer to the nearest tenth of a percent. O A. 26.2% . B. 30.5% O c. 31.1% O D. 28.8%
Answer:
31.1 best answer
sorry if it's wrong
28.8% is the probability that a data value is between 48 and 52.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
First, we need to standardize the values and use a standard normal distribution table or calculator.
The standardized value of 48 is:
z = (48 - 48) / 5 = 0
The standardized value of 52 is:
z = (52 - 48) / 5 = 0.8
Now we need to find the probability that a data value is between z = 0 and z = 0.8 in a standard normal distribution. We can use a standard normal distribution table or calculator to find this probability.
Using the table or calculator, we can find that the probability of a data value being between z = 0 and z = 0.8 in a standard normal distribution is approximately 0.2881.
Rounding this answer to the nearest tenth of a percent, we get:
P(48 < x < 52) ≈ 28.8%
Therefore, the answer is D, 28.8%.

Answer:
A) -30 - x = 10 and -30 - x = –10
Step-by-step explanation:
Part 1:
1) Isolate the variable x
-30 - x = 10
-x = 40
2) Multiply both sides by -1
x = -40
Therefore -30 - x = 10 is correct
Part 2:
1) Isolate the variable x
-30 - x = –10
-x = 20
2) Multiply both sides by -1
x = -20
Therefore -30 - x = –10 is also correct
Final Answer: -30 - x = 10 and -30 - x = –10

Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

Answer:
5. a = 4
7. x = -8
9. x = -1
11. p = 1.1
13. x = -1
15. x = -4
Step-by-step explanation:
2.9a = 11.6
2.9a/2.9 = 11.6/2.9
a = 4
-3.7x = 29.6
-3.7x/-3.7 = 29.6/-3.7
x = -8
(x-5)(-3) = 18
(x-5)(-3)/-3 = 18/-3
x-5 = -6
x-5+5 = -6+5
x = -1
3.6 = -2p+5.8
3.6-5.8 = -2p+5.8-5.8
-2.2 = -2p
-2.2/-2 = -2p/-2
1.1 = p
2x+6 = -4x
2x+6-6 = -4x-6
2x = -4x-6
2x+4x = -4x-6+4x
6x = -6
6x/6 = -6/6
x = -1
21-6x = -11-14x
21-6x-21 = -11-14x-21
-6x = -14x-32
-6x+14x = -14x-32+14x
8x = -32
8x/8 = -32/8
x = -4
Answer:
5.) a= 4
7.) x= -8
9.)x= -1
11.) p= 1.1
13.) x= -1
15.) x= -4
Step-by-step explanation:
5.) divide 11.6 by 2.9a
7.)divide 29.6 by -3.7u
9.) Divide by sides by -3. simplify. Add 5 to both sides. then simplify again x= -1
11.) subtract 5.8 from 3.6 . you're left with -2p=-2.2 divide both sides by -2. you get p=1.1
13.)Subtract 6 from both sides. You get 2x= -4x-6. Add 4x to both sides. then divide -6 by 6 you get x=-1
15.) Simplify both sides of the equation, so add 14x to -6x +21 side, you get 8x= -32 then divide -32 by 8x you get -4
