Answer:
AC = 30 in
m∠B = 36,9°
m∠A = 53,1°
Step-by-step explanation:
1 AC
You gan get AC with the pythagorean theorem:
a²+b²=c²
We are looking for side b of the triangle, so the equation is rearranged for b.
BC²+AC²=AB² | -BC²
AC²=AB²-BC²
AC=√(AB²-BC²)
Now the given values are used:
b=√(50²-40²)
b=√(2500-1600)
b=√900
b=30 in
2 m∠B
This angle can be calculated using the sine law:
sine(angle)=opposite cathete/hypothenus
We are looking for angle m∠B of the triangle.
sin(m∠B)=AC/AB
sin(m∠B)=30in/50in
sin(m∠B)=0,6
m∠B=36,9°
3 m∠A
This angle can be calculated using the sine law:
sine(angle)=opposite cathete/hypothenus
We are looking for angle m∠A of the triangle.
sin(m∠A)=BC/AB
sin(m∠A)=40in/50in
sin(m∠A)=0,8
m∠A=53,1°

Answer:
C. (1,760, 3,530, 5,280)
Step-by-step explanation:
In order to answer this question, you simply have to replace the variable 'x' with the 3 numbers Lilah has, which are 5,280, 10,560, and 15,840:
y(x) = 1/3 (5280) = 1760
y(x) = 1/3 (10560) = 3520
y(x) = 1/3 (15840) = 5280
So, the correct answer is C. (1,760, 3,530, 5,280)
Hope this helps :)

round 67,103 and 1,273 to nearest hundred
Answer:
67100
1300
Step-by-step explanation:
You are rounding to the nearest hundreds place value (will be underlined and bolded). Note the number directly next to the place value (tens place value). If it is the digit 5 or greater, round up. If 4 or less, round down:
67103:
You are rounding to the hundreds place value. The tens place value is a 0. Because 0 is less than 5, round down.
67103 rounded to the nearest hundred is 67100.
1273:
You are rounding to the nearest hundreds place value. The tens place value is a 7. Because 7 is greater than 5, round up.
1273 rounded to the nearest hundred is 1300.

Step-by-step explanation:
x + 9 = 4(x-1)²
x + 9 = 4(x² - 2x + 1) Multiply (x - 1) times (x - 1)
x + 9 = 4x² - 8x + 4
4x² - 9x - 5 = 0 Subtract x + 9 from both sides
Convert 9 3/4 to an improper fraction.
Answer:
39/4
Step-by-step explanation:
Because I multiplied 4 x 9 + 3
9 3/4 may be expressed as an improper fraction as 39/4 or 9.75.
What is Fraction?
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.
9¾ is a mixed fraction. 9 is the whole number whereas ¾ is the fractional part. 9¾ is also 9+¾.
Fractions that have a numerator greater than a denominator, such as 8/7 or 123/112, are considered improper fractions.
Thus, to convert 9 3/4 into an improper fraction, multiply the whole number component—in this case, 9, by the denominator (4 in this case). The multiple of 9 and 4 you just discovered is added to the numerator (3), which is then used as the numerator. The numerator (four) stays the same.
Therefore, 9 3/4 can be written as 39/4 or 9.75 in the terms of the improper fraction.

Ray OB divides 2 COA into two angles of equal measure.
True
False
Consider a number line with 40, 60 and 80 marked.
The value 60 is the midpoint of 40 and 80 since (40+80)/2 = 120/2 = 60
If we curved the number line to fit along the round edge of the protractor, then we'll get the diagram you see here.
Ray OB cuts angle COA in two equal pieces (angle COB, angle BOA). This is another way of saying "ray OB bisects angle COA".

On Saturday, 15,598 people attended a music festival. How does the value represented by the 5 in the hundreds place compare with the value of the 5 in the thousands place? A:The value in the hundreds place is 10 times as much as the value in the thousands place. B:The value in the hundreds place is one-tenth as much as the value in the thousands place. C:The value in the hundreds place is 100 times as much as the value in the thousands place.D: The value in the hundreds place is one one-hundredth as much as the value in the thousands place.
Answer:
B
Step-by-step explanation:
5 in the hundreds place equals 500, but put in the thousands place equals 5,000 and that's 10 times larger than 500. Or as how answer B puts it, 500 is one-tenth as much as 5,000. Either way, it's the same thing

Answer:
[tex]\displaystyle \frac{199}{18}[/tex]
Step-by-step explanation:
Fraction Operations
Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.
[tex]\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}[/tex]
[tex]\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}[/tex]
Now for the sum of the last two fractions:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}[/tex]
Make both denominators equal by multiplying by 2 both parts of the first fraction:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}[/tex]
[tex]\displaystyle =\frac{118+81}{14}=\frac{199}{14}[/tex]
Now multiply by 7/9:
[tex]\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}[/tex]
if f(x)=6x-9, find f(4)
Answer:
15
Step-by-step explanation:
f(x)=6x-9
so nw x value give 4,
substitute x value with 4
f(4)=6(4)-9
=19
A function assigns the values. The value of the f(4) will be equal to 15.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
For the given function f(x)=6x-9, therefore, the value of f(4) can be written as,
f(x) = 6x - 9
f(4) = 6(4) - 9
f(4) = 24 - 9 = 15
Hence, the value of the f(4) will be equal to 15.
