Answer:
x = 20
Step-by-step explanation:
m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:
2x + 3x - 10 = 90 add like terms
5x - 10 = 90 add 10 to both sides
5x = 100 divide both sides by 5
x = 20 to find the angles replace x with 20
m<ABC = 40 and
m<CBA = 50
a $2400 deposit for 8 years compounded at annual interest rate of 4.5% what is the interest and the total value
Answer:
$3,619.09
Step-by-step explanation:
liam deposits $2400 into an account that earns 8.3% interest compounded quarterly.
Compound interest formula is
where A is the final amount
P is the initial amount deposited
r is the rate of interest
n is the compounding period
t is the time in years
P= 2400, r= 8.3%= 0.083, t=5, n=4 (quarterly)
Plug in all the values
A= 3619.09
The profit that a company makes selling an item (in thousands of dollars) depends on the price of the item in dollars). If p is the price of
the item, then three equivalent forms for the profit are:
Standard form: -2p+ 24p - 54
Factored form: -20p - 3)(P-9)
Vertex form: -2(p - 6) + 18.
Which form is most useful for finding

2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. Start by using the distributive property with 2(x+1) --> 2x+2
2. Your equation will be 2x + 5 = 3 + 2x + 2
3. Add the 3 and the two on the left side to be 5 + 2x
4. Your equation will be 2x + 5 = 5 + 2x
5. Now minus 2x from both sides so the 2x will cancel out
6. 5 = 5

She measure the length of the trees shadow ( on the ground) which was 42 meters. Then she positioned the ladder. Which was 2.4 meters high, and measured its shadow. The ladders shadow ( on the ground) was exactly 3 meters
Answer:
The tree was 33.6 meters tall.
Step-by-step explanation:
So the question is "How tall is the tree?" I take it.
tree height/shadow length = ladder height / shadow length
Notice that the heights are both in the numerator. A proportion should always do this. It should have the same units on either the two denominators or the 2 numerators.
x / 42 = 2.4 / 3 Multiply both sides by 42
x = 42 * 2.4 / 3
x = 100.8 / 3
x = 33.6
Answer:
33.6
Step-by-step explanation:
x/42 = 2.4/3
x = 2.4/3 x 42
x = 2.4/1 x 14
x = 33.6/1
x = 33.6
What is the value of x?
Enter your answer in the box.
Step-by-step explanation:
2(x + 10) = 3x - 30
2x + 20 = 3x - 30
2x - 3x = -30 - 20
-x = -50
x = 50°

Is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer. HELP PLEASE VERY IMPORTANT
Answer:
The two triangles are congruent because the squares in the corner state it's 90 degrees, and the two tick marks show they are also congruent. \
Answer:
Yes
Step-by-step explanation:
Yes
ASA Criterion for Congruence
ASA Criterion stands for Angle-Side-Angle Criterion. Under ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.
Here Angle Q and Angle S are 90
and side QR = RS
and Angle QRP = Angle SRT (Vertically opposite angles)
By that we can prove these two triangles are congruent

what property should be used to solve this one-step equation : a-3=7
A Distributive Property
B Commutative Property of equality
C Associative Property of equality
D Addition Property of equality
Answer:
D
Step-by-step explanation:
a - 3 = 7 ( add 3 to both sides )
a - 3 + 3 = 7 + 3 , that is
a = 10

here is a easy question :- if -25/5 x p/q =1 , then p/q is equal to ?
9514 1404 393
Answer:
-1/5
Step-by-step explanation:
Divide by the coefficient of p/q:
-25/5 × p/q / (-25/5) = 1 / (-25/5)
p/q = -5/25
p/q = -1/5 . . . . in reduced form

find the value of z.
Answer:
z = 56
Step-by-step explanation:
z + 68 + z = 180
2z + 68 = 180
2z = 180 - 68
2z = 112
2z/2 = 112/2
z = 56
Step-by-step explanation:
since KJ and HI are parallel
z+68+z=180(cointerior angles sum up to 180)
2z+68=180
2z=180-68
2z=112
z=112/2
z=56
Find the 52nd term of the arithmetic sequence -8 -12 -16
Answer:
a₅₂ = - 212
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 8 and d = a₂ - a₁ = - 12 - (- 8) = - 12 + 8 = - 4 , then
a₅₂ = - 8 + (51 × - 4) = - 8 - 204 = - 212

Answer:
12
Step-by-step explanation:
23=r+11
r=23-11
r=12
Answer:
r=12
Step-by-step explanation:
We are given the equation 23=r+11. To solve for r, one side of the equation needs to be r, so we will isolate r by subtracting 11 on both sides:
23-11=r+11-11
12=r
Because the +11 and -11 cancel out, we are left with r on the right side of the equation and 12 on the left side. Therefore, the value of r is 12, or r=12.

I need answer for this quick please
Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 1, 4 ] , then
f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36
f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then
average rate of change = [tex]\frac{-36-(-6)}{4-(-1)}[/tex] = [tex]\frac{-36+6}{4+1}[/tex] = [tex]\frac{-30}{5}[/tex] = - 6
