21) 0.2800
22) 1.8750
23) 0.8000
24) 0.8000
Step-by-step explanation:
sin = opp/hyp
cos = adj/hyp
tan = opp/adj
19) sin Z = 40/50 = 0.8
20) sin C = 30/34 = 0.882352941
21) sin A = 7/25 = 0.28
22) tan X = 30/16 = 1.875
23) cos X = 28/35 = 0.8
24) cos C = 36/45 = 0.8

Answer:
Step-by-step explanation:
x² + 6x - 8 = 4x + 7
x² + 2x - 15 = 0
(x+5)(x-3) = 0
x = -5, 3
y = 4x + 7 = -13, 19
-13 + 19 = 6

Answer:
96
Step-by-step explanation:
100%-60%=40%
40% of x = 64 students (X=Total no. of students)
(40/100)*x=64
x=64*(100/40)
x=160
Missing no. of students=160-64=96
Answer:
96 students
Pls mark me brainliest!
Step-by-step explanation:
If an unknown amount of students is 60% of the students, the 64 of the students must be 40% of the students because 40+60 = 100.
You want to find what 1% equals, so we will divide 64 by 40 because 40% divided by 40 = 1% and whatever you do to one side you do to the other.
64/40 = 1.6
Assuming that the ? number of students that equals 60% will be a whole number, lets go with 1.6.
If 1.6 = 1%, and we want 60%, then multiply both sides by 60, because 1*60 = 60.
1.6*60 = 96

Answer:
a = 2 √13 cm
Step-by-step explanation:
Here, we want to find the length of BC
To do this, we can use the cosine rule
Thus;
a^2 = b^2 + c^2 - 2BC cos A
= 8^2 + 6^2 - 2(8)(6) cos 60
Mathematically cos 60 = 1/2
= 64 + 36 - 48 = 52
a^2 = √52
a = 2 √13 cm

Solve 1/4 +m ≤ 1/2
Answer:
[tex]m\leq \frac{1}{4}[/tex]
Step-by-step explanation:
[tex]\frac{1}{4}+m\leq \frac{1}{2}[/tex]
Simplify both sides in the inequality:
[tex]m+\frac{1}{4}\leq \frac{1}{2}[/tex]
Subtract 1/4 from both sides:
[tex]m+\frac{1}{4}-\frac{1}{4} \leq \frac{1}{2}-\frac{1}{4} \\m\leq \frac{1}{4}[/tex]
m ≤ 1/4 is your final answer.

Answer:
function is [tex]y = 3 (6^{x})[/tex]
Step-by-step explanation:
The general form for an exponential function is [tex]y = kb^{x}[/tex]. We need to find both k and b
(0, 3) is a point on the graph. So, let's substitute 0 in for x and 3 in for y
[tex]3 = k b^{0} = k(1) = k[/tex]
Now we know that k = 3
(1, 18) is a point on the graph. So, let's substitute 1 in for x, 18 in for y and 3 in for k
[tex]18 = 3 b^{1} = 3b\\6 = b[/tex]
Now we know that b = 6
Therefore, the function is [tex]y = 3 (6^{x})[/tex]

Find the domain of the graphed function
Answer:
D. 2 ≤ x ≤ 5
Step-by-step explanation:
Notice that there are no points on the graph for x ≤ 2 and x ≥ 5. Or another way to look at it is that the x's are between 2 and 5, inclusive.
The domain is the set of possible x values. Therefore, 2 ≤ x ≤ 5 is the set of values for the domain

There are 20 students in a math class. Thirty percent of the
students are randomly chosen to participate in a teacher
evaluation. How many combinations of students are possible?
Answer:
Step-by-step explanation:
20% of 30 is 6 are randomly selected.
30 choose 6 = 30! / (30-6)! 6!
= 30! / 24!6!
= 30 * 29 * 28 * 27 * 26 * 25
--------------------------------- <-- 24! cancels
6 * 5 * 4 * 3 * 2 * 1
= 29 * 28 * 27 * 26 * 25
---------------------------------- <--- 30 = 6 * 5 cancels
4 * 3 * 2 * 1
= 29 * 7 * 9 * 13 * 25 <-- 4 cancels 28, 3 cancels 27, 2 cancels 26
= 593775

Answer:
x= 1 , y=4
Step-by-step explanation:
x-y= -3 => Equation 1
x+5y= 21 => Equation 2
Substitution Method:
Substitute Equation 1=>
x=y-3 <= Equation 3
Put x=y-3 in Equation 2:
x+5y=21
( y-3)+5y=21
y-3+5y=21
6y-3=21
6y=21+3
6y=24
y=24÷6
y=4
Put y=4 in Equation 1:
x-y= -3
x-4=-3
x=4-3
x=1
Hope this helps :)
Answer:
x = 1
y = 4
Step-by-step explanation:
x - y = -3 then x = y - 3
x + 5y = 21
substitute for x:
y - 3 + 5y = 21
reduce:
6y = 24
y = 4
x = 4 - 3 = 1
check:
1 - 4 = -3
-3 = -3
and
1 + 5(4) = 21
21 = 21

he hypotenuse of a right triangle measures 13 cm and one of its legs measures 10 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
hypotenuse =13cm
base=10cm
perpendicular =?
Step-by-step explanation:
by using Pythagoras law
hypotenuse=perpendicular²+base²
13²=perpendicular²+10²
perpendicular =√(13²-10²)=√69=8.3cm
the measure of the other leg is 8.3cm
The measure of the other leg is 8.3 cm .
What is Pythagoras theorem?The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Formula of Pythagoras theorem :
(Hypotenuse)² = (Base)² + (Perpendicular)²
According to the question
Hypotenuse of a right triangle = 13 cm
Perpendicular of a right triangle = 10 cm
Now,
Base of a right triangle
By using formula of Pythagoras theorem :
(Hypotenuse)² = (Base)² + (Perpendicular)²
Substituting the values
(13)² = (Base)² + (10)²
169 = (Base)² + 100
69 = (Base)²
Base = [tex]\sqrt{69}[/tex]
Base = 8.3 cm
Hence, the measure of the other leg is 8.3 cm .

Find the values of x and y. y=? x=? PLEASE HELP
Answer:
x=15.714
y=5.715
Step-by-step explanation:
Answer:
x=10, y=20
Step-by-step explanation:
okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20
so 90+20+7x=180
and:110+7x=180
therefore: 7x=70
and finally: x=10
To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:
5x+2y=90
and we know x=10
so 5x=50
meaning that: 50+2y=90
therefore: 2y=40
and in conclusion y=20
