answer is 25
Step-by-step explanation:
for something like this you need to use the law of sins. First identify all the angles. There is a 90 degree angle and a 59 degree angle and those are clear. the missing angle is = 59 + 90 = 149
since a triangle has 180 degrees in total you say 180 - 149 = 31. the missing angle is 31 degrees. so we give the angles names. angle with 59 degrees will be angle A, 90 will be B and 31 will be C. So now we just give the sides names. let's replace that x with an a since it's across angle A. the side along angle B will be named b and the side along angle C will be named c. so you say:
Sin A/ a (sin A over a) = Sin B/b = Sin C/c
Sin A is what we are looking for so we say
59 degrees over/ x = sin 31 degrees/ 13 (we leave out the 90 degrees since we don't know the side and also we are not interested in it)
now we do cross multiplying.
say x ×sin 31 degrees = 13× sin 59
now divide these by sin 31
x = 13 × sin 59 ÷ 31 = 25

You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Answers
Answer:
12/27
Step-by-step explanation:
You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles
You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Assume all you picked is red( without replacement)
= 6/9 × 5/9
= 30/81
= 10/27
Assume all you picked is blue( without replacement)
= 3/9 × 2/9
= 6/81
= 2/27
The probability of the events is calculated as:
All red or All blue
= 10/27 + 2/27
= 12/27

Answer:
m=3.5h
Step-by-step explanation:
Just by looking at this, you know that it won't be either of the adding equations because it only works for the bottom input and output. So, we'll just look at the multiplying ones.
We know that multiplying should get us a bigger number (unless it's a fraction), so the equation h=3.5m won't work very well with this because h would be getting smaller not bigger.
That leaves us with m=3.5h.
To check this, I'll multiply 3.5 by 4 to see if it equals what m is on the table. Sure enough, it's 14. This also works with 2.5 and 8.75.

KP=126.2m
the length of string is 126.2m
Answer:
127.45 m
Step-by-step explanation:
Given :-
Height of kite = 65 m .Inclination of string = 31° .To Find :-
The length of the string .Solution :-
Here we need to find out the length of the string here if we imagine a right angle triangle in which the height of the kite will be the perpendicular of the triangle and the length of the string will be the hypotenuse of triangle .
And the angle between the the string and the ground will be 31°.
Here we can use ratio of sine as ,
> sin∅ = p/h
> sin 31° = 65m/ h
> h = 65m/sin 31°
> h = 65m/0.51
> h = 127 .45 m

yokoreceived a 70 gift card for a coffee store. She used it in buying some coffee that cost 8.04 per pound. After buying the coffee, she had 45.88 left on her card. How many pounds of coffee did she buy?
Answers
Answer:
Since she started with $80 and ended with with $35,24, we can find the total amount she spent by subtracting these amounts:
$80 - $35.24 = $44.76
This means that she spent $44.76 on coffee. If each pound cost $7.46, we can divide $44.76 by $7.46 to see how many pounds she bought (ignoring tax):
44.76 / 7.46 = 6 pounds of coffee purchased

Answers
Answer:
[tex]Q_1 = 498[/tex]
[tex]Q_3 =1052[/tex]
Step-by-step explanation:
Given
[tex]Data: 777,\ 498,\ 619,\ 379,\ 895,\ 1,256,\ 1052[/tex]
[tex]n = 7[/tex]
First, the data has to be arranged:
[tex]Data: 379,\ 498,\ 619,\ 777,\ 895,\ 1052,\ 1256[/tex]
Solving (a): Lower Quartile
This is calculated as:
[tex]Q_1 =\frac{1}{4} * (N + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * (7 + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * 8th[/tex]
[tex]Q_1 = 2nd[/tex]
The 2nd data is 498
Hence:
[tex]Q_1 = 498[/tex]
Solving (b): Third Quartile
This is calculated as:
[tex]Q_3 =\frac{3}{4} * (N + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (7 + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (8)th[/tex]
[tex]Q_3 =6th[/tex]
The 6th data is 1052
Hence:
[tex]Q_3 =1052[/tex]
Solving (c): Interquartile Range
This is calculated as:
[tex]IR = Q_3 - Q_1[/tex]
[tex]IR = 1052- 498[/tex]
[tex]IR = 554[/tex]
Find the value of if the perimeter of the rectangle is 30inches. The length is 2x + 3and the width is x
Answers
Answer:
The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.
Step-by-step explanation:
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = x
Length = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,
30=2x+4x+6 combining like terms
30=6x+6 subtracting 6 from both sides,
24=6x divide both sides by 6
4=x This means that the width is 4 m
To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for
L=2(4)+3
L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m

Answers
Answer:
7.2 inches
Step-by-step explanation:
First, we find the length of the legs, which are the sides that are parallel to the x- and y-axis.
The leg parallel to the x-axis is 6 inches long.
The leg parallel to the y-axis is 4 inches long.
After finding the length of both legs, we can use the Pythagorean Theorem to find the length of the hypotenuse: a² + b² = c²
a and b being the legs, and c being the hypotenuse
6² + 4² = c²
36 + 16 = c²
52 = c²
√52 = c
c ≈ 7.2 inches
