Answer:
x=21/5, also known as 4.2
Step-by-step explanation:
5x:9 = 7:3
Solve it like a proportion and get any of these answers
5x/9 = 7/3
cross product property
3(5x) = 63
15x = 63
x = 63/15 = 21/5 in fraction form = 4.2 in decimal form

Select the procedure that can be used to show the converse of the
Pythagorean theorem using side lengths chosen from 2 cm, 3 cm, 4 cm, and
5 cm
Answer:
The correct option is C
Step-by-step explanation:
I attached an image that forms the complete question.
The converse Pythagorean theorem states that, "If the square of the longest side of a triangle is equal to the square of the other two sides, then the triangle is a right triangle."
That is if c is the longest side of a triangle and then a and b are the other sides, then if,
c² = a² + b², the triangle is a right triangle.
Looking at all the options, option C fits the theorem well. Because
3² + 4² = 5² implies the triangle is a right triangle and the converse theorem is established.
The option D also looks close, but it's not correct because you can just draw any two sides and put the right angle in between them. The longest is always the part of the triangle that is opposite to the right angle, 90°. If for instance, you draw 3 and 5 then put the right angle in between them, 4 will take the position of the longest side which is wrong.
Therefore, the correct option is c.

c

The present value in a savings account is $420. It is receiving 3% annually compounded monthly. What is the future value in 2 months?
Answer:
$422.10
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value (PV) = $420
Rate of interest( compounded monthly) = 3% annually
so, rate of interest per month (r) = 3 ÷ 12 = 0.25% per month
Time period (n) = 2 months
so, by putting the value in excel FV formula, we get.
Attachment is attached below.
Future value in 2 months = $422.10
An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3820 and his stock in Company B was worth $2960. The stock in Company A has increased 15% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answer:
10.6%
Step-by-step explanation: Find new values:
3820(1+0.15)=\color{green}{4393}
3820(1+0.15)=4393
2960(1+0.05)=\color{blue}{3108}
2960(1+0.05)=3108
Last Year This Year
Stock A 3820 4393
Stock B 2960 3108
Total 6780 7501
\text{Find overall increase:}
Find overall increase:
6780(1+r)=7501
6780(1+r)=7501
\frac{6780(1+r)}{6780}=\frac{7501}{6780}
6780
6780(1+r)
=
6780
7501
1+r=1.106342
1+r=1.106342
r=0.106342
r=0.106342
Subtract 1
\text{Final Answer: }10.6\%
Final Answer: 10.6%

A ladder is leaning against a vertical wall. The distance from the top of the ladder to the base of the wall is 17 feet. The distance from the base of the wall to the bottom of the ladder is 7 feet. What is the length of theladder (nearest tenth)?
Answer:
18.4 feet
Step-by-step explanation:
-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.
-let the ladder be C, the wall be a, the base to the bottom be b.
-substitude into the equation, which will leave us with:
C^2 = 17^2 + 7^2
C^2 = 289 + 49
C^2 = 338
C = square root of 338, which is 18.4 feet!

D. 10
Sorry if I keep asking and making questions lol
Answer:
The correct answer is D
Step-by-step explanation:

A. x = 9, y = 14; 11, 20
B. x = 14, y = 9; 11, 11
C. x = 14, y = 9; 6, 16
D. x = 9, y = 14; 6, 16
Answer:
So, the correct option is A. x = 9, y = 14 , Sides are 11 and 20
Step-by-step explanation:
P.S - the exact question is -
As given in the question ,
Side AB = Side AD
⇒y - 3 = x + 2
⇒y - x = 2 + 3 = 5
⇒y - x = 5 .........(1)
Also, given
Side BC = Side CD
⇒2x + 2 = x + 11
⇒2x - x = 11 - 2
⇒x = 9
∴ equation (1) becomes
y - 9 = 5
⇒y = 5 + 9 = 14
⇒y = 14
∴ we get
x = 9, y = 14
Now,
as given ,
Side AB = y - 3
⇒ AB = 14 - 3 = 11
Side BC = 2x + 2
⇒ BC = 2(9) + 2 = 18 + 2 = 20
Side CD = x + 11
⇒ CD = 9 + 11 = 20
Side DA = x + 2
⇒DA = 9 + 2 = 11
∴ we get
The sides are 11 and 20
So,
The correct option is A. x = 9, y = 14 , Sides are 11 and 20

Subtract 4x + 2y - 16z from ( -12x + 2y - 4z ).
Answer:
Step-by-step explanation:
4x + 2y - 16z - (-12x + 2y - 4z)
4x + 2y - 16z + 12x - 2y + 4z
16x - 12z
consider the expression 7 - 4y. Why would the co-efficient be -4 and not 4?
Answer:
because a co-efficient is the multiplicative factor in polynomials and it's minus 4 before the y. you would just take the minus and put it with the 4 otherwise it would just be floating there ig.

What is the value of x in the equation 3(2x + 8) = 0? (4 points)
a
−8
b
−4
c
4
d
8
Answer:
B, -4
Step-by step explanation
Step 1: Simplify both sides of the equation.
3(2x+8)=0
(3)(2x)+(3)(8)=0(Distribute)
6x+24=0
Step 2: Subtract 24 from both sides.
6x+24−24=0−24
6x=−24
Step 3: Divide both sides by 6.
6x/6= -24/6
Answer: x= -4
