Calculate the length of CD.
Give your answer to 3 significant figures.
C
12 cm
55°
А
D
B 6 cm
Answer:
12.7 cm
Step-by-step explanation:
Pythagoras theorem
c²=a²+b²
12²=6²+b²
144=36+b²
minus 36 on both sides
108=b²
then square root on both sides
b=10.4
wait I'm not done
then we use the sin rule which is
sinx=O
--
H
so
sin(55)=10.4 over H
cross multiply
10.4 over sin 55 which equals 12.7

Answer:
The formula, I=PRT is used to calculate simple interest.
I=Interest
P=Principal
R=Interest Rate
T=Time
In this case, P=500, R=3%, T=9 months.
Multiplying this out, we obtain a final interest of 135 dollars.

Slope (Given a Graph or Ordered Pairs)
Answer:
Step-by-step explanation:
1. 5/2
Using the two points you do rise over run.
2. zero
Any line that is horizontal is equal to zero (0
3. undefined
Any line that is vertical is undefined
4. The equation always is:
y^2-y^1/x^2-x^1
to find slope.
Label your ordered pairs according to the formula:
x^1 = -12
y^1 = -1
x^2 = -3
y^2 = -4
substitute
y^2-y^1/x^2-x^1
= -12 — -1 / -3 — -4
solve
-12 — -1 = -11
-3 — -4 = 1
-11/1 = -11
5. The equation always is:
y^2-y^1/x^2-x^1
to find slope.
Label your ordered pairs according to the formula:
x^1 = -11
y^1 = -1
x^2 = 7
y^2 = -2
substitute
y^2-y^1/x^2-x^1
= -11 — -1 / 7 — -2
solve
-11 — -1 = -10
7 — - 2 = 9
-10/9
I hope this is right...

Answer:
1.
Angle 2 = Angle 4 (alternate angles)Angle 1 = Angle 5 (corresponding angles)2.
Angle 1 + Angle 2 + Angle 3 = 180 (angles on a line)
Now,
Angle 2 = Angle 4 (alternate angles)
and Angle 1 = Angle 5 (corresponding angles)
So,
Angle 1 + Angle 2 + Angle 3 = Angle 5 + Angle 4 + Angle 3 = 180

rewrite the expression 6 2/4 + 9 3/4x + 5 3/4 + 7 3/4x
Answer:
3(16x+9)/4
make sure it's a fraction
Answer:
27 11/4x
Step-by-step explanation:
First we add the similar parts of the expression.
Whole numbers
6 + 9 + 5 + 7 = 27
Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x
Now we combine those parts together, making
27 11/4x

How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

What is the degree of the polynomial given below?
F(x) - 2x3 - x2 +5x - 3
Answer:
3
Step-by-step explanation:
3 is the degree of polynomial \(f(x) = -2x^3-x^2+5x-3\)
=> Degree of the polynomial is the highest power/exponent contained by the variable in the expression.
Answer:
The degree of the polynomial would be 3, since 3 is the largest exponent

Antonio graphs these equations and finds that the lines intersect at a single point, (-5,0.25)
Answer:
Answer C.
Step-by-step explanation:
If x= -5 and y= 0.25
Equation A : 4 * 0.25 - 3 * -5 = 16
Equation B: -(-5) -8*0.25=3
These are only coordinates that satisfy the equation.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given coordinates: (-5, 0.25)
Equation A: 4y - 3x= 16
So, 4(0.25)- 3 (-5)
= 1+ 15
= 16
and, Equation B: -x -8y= 3
So, -(-5) -8 (0.25)
= 5 - 2
= 3
Hence, these are only coordinates that satisfy the equation.

93-11=82
82-67=15
Answer:
D. 15

he hidden question is what the temperature was four days prior to the record high temperature of 39°C.
To find the temperature four days earlier, subtract 14.2°C from the record high temperature of 39°C:
39°C - 14.2°C = 24.8°C
The main question is how much higher the record temperature was than the high temperature four days earlier.
To find the answer, subtract the temperature four days earlier (24.8°C) from the record high temperature (39°C):
39°C - 24.8°C = 14.2°C.

Cameron has 75% as many shirts as her brother. How many shirts does her brother have if Cameron has 9 shirts?
A. 3 shirts
B. 9 shirts
C. 12 shirts
D. 16 shirts
Answer:
The number of shirts that Cameron's Brother has is:
C. 12 Shirts
Step-by-step explanation:
Cameron has 75% as many shirts as her brother.
let the number of shirts Cameron has be= C
let the number of shirts Cameron's brother has be= B
Then, C=9 (Given)
Since,
Cameron has 75% as many shirts as her brother.
So,
C=75/100 X B
9=75/100 X B
9X100/75=B
B=9X100/75
75/100 can be reduced to the fraction 3/4,
as 75= 25X3 and 100=25X4
Thus,
B=9X100/75
B=9X4/3
3 cancels 9 to leave 3,
Thus,
B=3X4
B=12
So,
Answer=12 Shirts
Number of shirts that Cameron's Brother has are 12
