In ABC, angle C is a right angle. Which statement must be true
Answer:
a
Step-by-step explanation:
a because the the sin is opposite divided by hypotenuse and the opposite of a is 12 and the hypotenuse is 13 so sin a would be 12/13
this is equals to the cosine of b because cos is adjacent/hypotenuse and the adjacent of b is 12 and the hypotenuse is 13 so cos b would be 12/13
hope this helps :)
what Is the answer to 1/6 + 2/3
Answer:
5/6
Step-by-step explanation:
When adding fractions, you must ensure the denominator is the same in both fractions.
In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.
When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.
2/3 × 2/2 = (2×2)/(3×2) = 4/6
Replace 2/3 with its equivalent 4/6.
Now you will add the numerators together.
1/6 + 4/6 = (1+4)/6 = 5/6
Your final answer is 5/6
Answer:
5/6
Step-by-step explanation:
2/3--> 4/6 (GCF)
4/6+1/6=5/6

Answer:
Mean: 20
Median: 20
Mode: 5, and 20
Range: 30
Step-by-step explanation:
Mean: Add all the numbers up then divide by the total of numbers there are. 5+30+35+20+5+25+20=140 divided by 7
Median: middle number, list all the numbers from greatest to least and whatever number is in the middle is your answer (5, 5, 20, 20, 25, 30, 35)
Mode: Number that is repeated the most. 5, and 20

Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
f(x) = 5x - 5
Step-by-step explanation:
Let the equation of the linear function is,
f(x) = mx + b
Here, m = Slope of the graph
b = y-intercept
Slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]
From the table attached,
Slope of the line passing through (2, 5) and (6, 25) will be,
m = [tex]\frac{25-5}{6-2}[/tex]
m = 5
Equation of the linear function will be,
f(x) = 5x + b
Since, a point (10, 45) lies on the function,
45 = 5(10) + b
b = 45 - 50
b = -5
Equation of the linear function will be,
f(x) = 5x - 5
In order to make a safe parachute landing from a mountain top, you must be at least 9,000 feet in the air. At the top of Mount Montgomery, the angle of depression is 19 degrees looking diagonally down at a landing zone that is 16000 feet away from the middle of the mountain. Determine if it is safe to use a parachute from the top of this mountain.
Answer:
Send me a picture I can help u
Answer:
Step-by-step explanation:
tan19=h/16000
h=16000tan19
h=5509.24ft
So it is less than 9000ft and is unsafe to use the parachute.

Ms. Jones baked 25 cookies. 4 fifths of the cookies were oatmeal. How many oatmeal cookies did Ms. Jones bake?
Hi there!
20 outmeal cookies..
Convert fraction into number term:
[tex]\frac{4}{5}=\frac{20}{25}=20[/tex]
Therefore, there would be 20 oatmeal cookies.

Solve this system by substitution. y = 3 y = -3x + 6 *Remember to write your answer as a coordinate point (x, y). I
Answer:
(1, 3)

Order of Operations: BPEMDAS
BracketsParenthesisExponentsMultiplicationDivisionAdditionSubtractionLeft to RightEquality Properties
Multiplication Property of EqualityDivision Property of EqualityAddition Property of EqualitySubtraction Property of EqualityAlgebra I
Coordinates (x, y)Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = 3
y = -3x + 6
Step 2: Solve for x
Substitute in y: 3 = -3x + 6[Subtraction Property of Equality] Subtract 6 on both sides: -3 = -3x[Division Property of Equality] Divide -3 on both sides: 1 = xRewrite/Rearrange: x = 1Step 3: Solve for y
Define original equation: y = -3(1) + 6Multiply: y = -3 + 6Add: y = 3Tyler needs to complete this table for his consumer science class. He knows that 1 tablespoon contains 3 teaspoons and that 1 cup contains 16 tablespoons.
What are the values of t, x, y, and c ?
Answer:
Step-by-step explanation:
This table reflects the proportional relationship amongst number of teaspoons, number of tablespoon, number of cups.
In other words these three measures are proportional.
By taking proportionality ratio of 'number of tablespoons' and 'number of cups' first.
[tex]\frac{12}{48}=\frac{C}{3}[/tex]
C = [tex]\frac{12\times 3}{48}[/tex]
C = 0.75
Similarly, [tex]\frac{y}{2}=\frac{12}{C}[/tex]
[tex]\frac{y}{12}=\frac{2}{0.75}[/tex]
y = [tex]\frac{24}{0.75}[/tex]
y = 32
Now, [tex]\frac{t}{36}=\frac{y}{12}[/tex]
[tex]\frac{t}{36}=\frac{32}{12}[/tex]
t = 96
By the same rule,
[tex]\frac{36}{x}= \frac{12}{48}[/tex]
x = [tex]\frac{48\times 36}{12}[/tex]
x = 144
Therefore, complete table will be,
Number of teaspoons Number of tablespoons Number of cups
96 32 2
36 12 0.75

FE/sin38=18/sin90
FE=18sin38=11.08
DF/sin52=18/sin90
DF=18sin52=14.2
Answer:
FE = 11.08, DF = 14.18Step-by-step explanation:
Use trigonometric ratios:
sin = opposite / hypotenusecos = adjacent / hypotenuseApply to the given triangle
Side FE
FE / DE = sin 38° (or cos 52°, the value is same)FE / 18 = sin 38°FE = 18 sin 38°FE = 11.08Side DE
DF / DE = sin 52° (or cos 38°, the value is same)DF / 18 = sin 52°DF = 18 sin 52°DF = 14.18Can someone help me please!

how many solutions does -3x + 3y =4 -x + y =3 have?
-3x + 3y =4
-x + y =3
0
1
2
infinite
Answer:
0
Step-by-step explanation:
-3x + 3y = 4
-x + y = 3
3y = 3x + 4
y = x +4/3
-x + (x+4/3) = 3
4/3 = 3
This is an equality there for no solution.
