whats the answer
Answer:
11
Step-by-step explanation:
15-4 = x
15-4 = 11

to isolate x, you move 4 to the other side and it becomes 15-4 = x
Find the gradients of line a and b
════════ ∘◦❁◦∘ ════════
Answer• Line A = 4
• Line B = (-2)
═══════════════════════
Formula of the gradient[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

y2 = 14
• Line B

Way to find gradient•Line A
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{14 - ( - 6)}{5 - 0} = \frac{20}{5} = 4[/tex]

Abby is registering at a Web site and must select a six-character password.The password can contain either letters or digits.
a.How many passwords are possible if characters can be repeated? if no characters can be repeated?
b.How many passwords are possible if all characters are letters that can be repeated? if the password must contain exactly one digit? Which type of password is more secure? explain
Answer:
a. 2176782336 with repeated characters. 1402410240 with no repeated characters.
b. 7964171460 when all letters can be repeated, but not numbers. 118813760 when only one number and letters can be repeated.
I believe that the password with all letters able to repeat and numbers not being able to is the most secure password, because if someone were to guess the password there is a 1/7964171460 chance of guessing the password.
Step-by-step explanation:
A. Since there are 26 different letters and 10 different numbers, there are 36 characters we can type. If characters can be repeated then, there is 2176782336 different passwords, since on all six number there are 36 possibilities each. So, 36 x 36 x 36 x 36 x 36 x 36 or 36^6 is to evaluated to find the answer. If characters are not to be repeated, there are 1402410240 different passwords, since on the first number there are 36, second has 35, third has 34, fourth has 33, fifth has 32, and sixth has 31. So, 36 x 35 x 34 x 33 x 32 x 31 is to be evaluated to solve this.
B. Since all characters that are letters can be repeated, then there are 26 letters to use forever and 10 numbers you can use with a limit. So, 36 x 35 x 34 x 33 x 32 x 31 which is to be solved if only numbers were to be used, which is 1402410240. Then, you add that with 36 x 35^5 and 36 x 35 x 34^4 and 36 x 35 x 34 x 33^3 and 36 x 35 x 34 x 33 x 32^2. which will be 7964171460. If the password must contain one digit, then you must multiply 10 with 26^5. Since, there is 10 different digits to use for the first number and 26 letters to choose from for the other five. So, it will be 26^5 times 10 which is 118813760.
Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.
Answer:
[tex]10cm^2[/tex]
Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are
[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]
[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]
Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]
Area of trapezoid=[tex]10cm^2[/tex]
Solve the simultaneous equations.
Please help
Answer:
x=1/2, y=4
Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2
x=1/2
In the parallelogram below find the value of q
Answer:
q = 9
Step-by-step explanation:
we can see it is a parallelogram so opposite sides are equal.
q - 3 = 6 ( being opposite sides of parallelogram)
q = 6 + 3
q = 9
When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?
Answer: Rs. 25,300
Step-by-step explanation:
First find the original price of the plot:
Assume this price is x:
x * ( 1 - 15%) = 18,700
0.85x = 18,700
x = 18,700/0.85
x = Rs. 22,000
To make a gain of 15%, sell at:
= 22,000 * (1 + 15%)
= 22,000 * 1.15
= Rs. 25,300

Answer:
13.7ft^2
Step-by-step explanation:
Area for triangle:
The formula for the area of a triangle in this scenario is area=(b*h)/2
The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:
area=(3.6*4.8)/2
area=8.64ft^2 for the triangle
Area for semi-circle:
The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.
The question says to use 3.14 for the value of pi.
The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius
Now, we can just substitute these values into the equation above. So:
area=3.14*(1.8)^2
area=3.14*3.24
area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).
However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:
10.1736/2=5.0868ft^2 for the semicircle.
Total area of shape
Now we have the area of the two separate shapes, we can simply add them together. So:
8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)
Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.
Hope this helped!!

For a science experiment, Jack adds 1 tsp of salt to 3 tsp of water. Mika adds 4 tsp
of salt to 9 tsp of water. Whose water is saltier?
Answer:
Mika
Step-by-step explanation:
Jack's water is 1/3 salty water while Mika's water is 4/9 salty water and 1/3 = 3/9. 4/9 is greater than 3/9 so mika's is saltier.
For this sequence, 1, 5, 25, 125, 625 ... state if it is arithmetic, geometric, or neither.
A. Arithmetic
B. Neither
C. Geometric
Answer:
Geometric sequence
Step-by-step explanation:
A geometric sequence is when you multiply or divide with a constant number. So in 1, 5, 25, 125, and 625, we're multiplying by 5 every time. I hope this helped :)

Does the line passing through the points (3,3) and (7,11) intersect the line passing through the points (5,8) and 13,24) ?
Answer:
no they don't intersect
Step-by-step explanation:
line 1:
m=11-3/7-3=8/4=2
y-3=2(x-3)
y-3=2x-6
y=2x-3
line 2:
m=24-8/13-5=16/8=2
y-8=2(x-5)
y-8=2x-10
y=2x-2
no they don't intersect cause they are parallel and parallel lines don't cross

Answer:
B
Step-by-step explanation:
Soemthing is a function if it can pass the vertical line test
the vertical line test is when you draw a vertical line and it only touches the graph once
Another way of thinking about this is no function can have two of the same values on the x axis
