the 4. In the figure, find length of side A AB. 17 15 ph
Answer:
8
Step-by-step explanation:
Look like BC is 15 and AC is 17
The Pythagorean Theorem states that a^2 + b^2 = c^2
so AC^2 = AB^2 + BC^2
17^2 = AB^2 + 15^2
289 = AB^2 + 225
AB^2 = 64
AB = 8
which expression is equivalent to 4/6 of 36 ?
Answer:
First, find the answer for 36 ÷ 4. Which is 9.
Now calculate each expression until you get the answer of 9.
4 ÷ 36 = 4 * 1/36 = 4/36 = 1/9
36 ÷ 1/4 = 36 * 4 = 144
1/36 * 1/4 = 1/144
36 * 1/4 = 36/4 = 9
So, the last option is the answer. D. 36 * 1/4.
Answer:

Step-by-step explanation:
36 divided by 4/6 and you 35 1/3

The area of the triangle is 216 square centimeters
How to calculate the surface areaThe dimension of the triangle is given as:
Base = 27 cm
Height = 16 cm
The area of the triangle is then calculated as:
Area = 0.5 * Base * Height
So, we have:
Area = 0.5 * 27 cm * 16 cm
Evaluate the product
Area = 216 square cm
Hence, the area of the triangle is 216 square centimeters

Mr. Jenkins recorded the amount of weight he lost in six months.
If Mr. Jenkins wanted to brag about losing the most weight, which measure of central tendency would he use?
Answer: Mr. Jenkins would use 'mean'.
Step-by-step explanation:
Rather than use either median or mode, he would use mean. Mean is a statistical average of numbers. It would be best to brag about the total weight that he has lost rather than using the half-way point or the most frequent appearing number in the data.

Given sin x = a/2 and tanx< 0 find cos x
Answer:
cosθ = ( √4 - a² ) ÷ 2
Explanation:
sinθ = a/2
according to sincostan rule:
sinθ = opposite/ hypotenuse
cosθ = adjacent/ hypotenuse
so here opposite is a and hypotenuse is 2
adjacent² + opposite² = hypotenuse²
adjacent² + a² = 2²
adjacent = √4 - a²
we found our adjacent.
so cosθ = adjacent/ hypotenuse
= ( √4 - a² ) / 2
so cosθ = [tex]\frac{ \sqrt{4 - a^{2}} }{2}[/tex]

Answer:
No, it's not long enough

The perimeter of the square is 4/5. P=4s where s is the side length. 4/5 is larger than 5/8, so there will not be enough lights to cover the whole perimeter.

Somebody help Janele! XD
quartz gym....interesting, janele
Answer:
D
Step-by-step explanation:
So when making these equations, there's always going to be an initial value and then a variable
In this case, x represents the unknown cost for each class that Janele took at the rock climbing gym. She took 6 classes, so that's represented by 6x
50 is the initial value. The initial value is a value that is constant, or stays the same. It doesn't change based on variables like how many classes she took.
The total cost of everything was 92 dollars
So then ur equation would be
6x + 50 = 92
Because both the initial cost of 50 dollars and the cost of the classes equal to 92
lol Janele and the quartz gym, some of these math problems really do be interesting. like jim and his 100 watermelons from costco
What two numbers multiply to get -40 and add up to get -3
Answer:
5 and -8
Step-by-step explanation:
First, list the set of pairs of numbers that multiply to give 40 (so "factors" of 40):
1 40
2 20
4 10
5 8
Now look at the pairs to see which has a difference of 3.
1 and 40 has a difference of 39
2 and 20 has a difference of 18
4 and 10 has a difference of 6
5 and 8 has a difference of 3
Now all we need to do is determine whether 5 or 8 will be negative (if they are both negative, the product will be positive, so only one needs to be negative to have a product of -40).
As we need a final result of -3, the two numbers will be: 5 and -8 (as 5 + - 8 = -3)
Answer:
5 and -8
Step-by-step explanation:
First I listed all the factors of 40 : 1, 2, 4, 5, 8, 10, 20 and 40.
Then out of those, I just had to find a pair with a difference of 3.
Or in other words, when I subtracted one from the other I either got 3 or -3.
The only pair that worked out that way when subtracted was 5 and 8.
However, if we multiply 5 and 8 we get 40, not -40, so something was amiss. When we add them up we have to get -3, and that only worked out if it was -8 and 5, since -8 + 5 = -3.
Therefore, the two numbers are -8 and 5

The first two terms in an arithmetic progression are 57 and 46. The last term is -207. Find the sum of all the terms in this progression.
Answer:
-1875
Step-by-step explanation:
An arithmetic sequence has a common difference as a sequence. Here the common differnece is -11.
So our sequence so far looks like,
(57,46,35,24....). We know the last term of the sequence is -207 and we need to find the nth term of that series so we use arithmetic sequence
[tex]a _{1} + (n - 1)d [/tex]
where a1 is the inital value,
d is the common differnece and n is the nth term.
We need to find the nth term so
[tex]57 + (n - 1)( - 11) = - 207[/tex]
[tex](n - 1)( - 11) = - 264[/tex]
[tex]n - 1 = 24[/tex]
[tex]n = 25[/tex]
So the 25th term of a arithmetic sequence is last term, now we can use the sum of arithmetic sequence
which is
[tex] \frac{a _{1} + a _{n} }{2} n[/tex]
[tex] \frac{57 + ( - 207)}{2} (25) = [/tex]
[tex] \frac{ - 150}{2} (25)[/tex]
[tex] - 75(25) = - 1875[/tex]
Answer:
-1875
Step-by-step explanation:
57 , 46 , ......... -207
[tex]First \ term = \ a_{1} = 57\\[/tex]
common difference = d = second term - first term = 46 - 57 = -11
[tex]n^{th} \ term = -207\\\\a + (n-1)*d=t_{n}[/tex]
57 + (n-1)* (-11) = -207
57 - 11n + 11 = -207
-11n + 68 = -207
-11n = -207 - 68
-11n = -275
n = -275/-11
n = 25
[tex]S_{n}=\dfrac{n}{2}(a_{1}+l)\\\\\\S_{25}=\dfrac{25}{2}*(57 + (-207) )\\\\\\ =\dfrac{25}{2}* (-150)\\\\\\= 25 *(-75)\\\\= -1875[/tex]

Answer:
B
Step-by-step explanation:
Since the triangle has 2 equal base angles (45 degrees) and 1 angle is 90 degrees, the triangle is an isosceles right triangle.
We let a be the length of one side of the right angle, so the length of the other side is also a. Applying the Pythagorean theorem we have a^2 + a^2 =14^2 => a=[tex]7\sqrt{2}[/tex]
We have the area of an equilateral triangle 1/2 the product of the lengths of the 2 sides of the right angle. S=1/2*[tex]7\sqrt{2} * 7\sqrt{2}[/tex]=49

What is the slope and y-intercept?
Step-by-step explanation:
the slope is the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, for example, when using the first 2 points (0, -5) and (1, -3) we see
x changes by +1 (from 0 to 1)
y changes by +2 (from -5 to -3).
so, the slope is +2/+1 = 2
the y-intercept is the y value when x=0. so in this case -5.
this is because it identifies the point where the line intercepts the y-axis (which is the reason why x=0).
the intercept point is then (0, -5).
