Congruency All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Define
3(x + 7)° = 63°
3(x + 7)° + 63° + y° = 180°
Step 2: Solve for x
Divide 3 on both sides: x + 7 = 21 Subtract 7 on both sides: x = 14Step 3: Solve for y
Substitute in x: 3(14 + 7) + 63 + y = 180(Parenthesis) Add: 3(21) + 63 + y = 180Multiply: 63 + 63 + y = 180Combine like terms: y + 126 = 180Isolate y: y = 54write a point-slope foem an equation of the line that passes through the given point and has the given slopes (2,-2); m = -5?
a. y -2 = -5(x -2)
b. y+2 = -5(x +2)
c. y -2= -5(x+2)
d. y +2= -5(x -2)
Answers
Answer:
y+2 = -5(x-2)
Step-by-step explanation:
The point slope form of a line is
y- y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -2 = -5(x-2)
y+2 = -5(x-2)

D.the amount of profit after the first year was around $30,000.
E. The amount of profit after 10 years is approximately $120,000.
Answers
Answer:
Step-by-step explanation:
We want to confirm which of the given statement is true about the graph.
A) the amount of profit after the first year was around $0
-----------false
From the given graph, the amount of profit after year was far more $0. So the statement above is false.
B) The amount of profit increases about $10,000 each year ------------true
From the line of best fit shown in the graph, the amount of profit increases each year by approximately $10,000.
C) the amount of profit decrease about $10,000 each year ------------ False
From the line of best fit on the graph, we can observe that the amount of profit does not decrease. It rather increases every year.
D) the amount of profit after the first year was around $30,000 ------------true
From the given graph, the amount of profit after the first year is approximately $30,000.
So, the statement is true.
E) the amount of profit after 10 years is approximately $120,000 --------- true
At the year 10 on the graph , the corresponding amount of profit is $120,000.

A $270 suit is marked down by 20%. Find the sale price
Answers
Answer:
Marked down means the price has decreased by 20% so 100%-20%=80%
The suit is now 80% of its original price of 270.
So 270×(80/100)= 216
The selling price of the suit will be equal to $216.
What is the percentage?
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a $270 suit is marked down by 20%. The selling price will be calculated as,
Marked down means the price has decreased by 20%,
100%-20%=80%
The suit is now 80% of its original price of 270.

Answers
Answer:
10 Gallons of water will weigh 1.2 pounds.
Step-by-step explanation:
Each gallon weighs 0.12 pounds, I got this answer from dividing 3 by 25 to see how much one gallon weighs. So if we multiply the weight of one gallon by 10, 0.12*10, then we will find out the weight of ten gallons.
I hope this helped you!! You can ask questions any question you may have, if needed, and I will answer them :)
10 Gallons of water will weigh 1.2 pounds.
Here, we have,
given that,
Morgan know that 3 gallons of water weigh 25 pounds.
now, we need to find how much do 10 gallons weigh.
so, we get,
3 gallons of water weigh 25 pounds.
so, to see how much one gallon weighs we divide 3 by 25 .
i.e. 3/25 = 0.12
Each gallon weighs 0.12 pounds,
So if we multiply the weight of one gallon by 10,
i.e. 0.12*10, then we will find out the weight of ten gallons.
so, we get,
10 gallons weigh = 0.12*10 = 1.2 pounds.

Where;
wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.
To obtain the constant b,
y= ae^-bt
Substituting values;
1000 = 3000 e^-b(50)
1000/3000 = e^b(50)
0.33 = e^b-(50)
ln (0.33) = ln(e^b(-50))

If a right triangle has sides of length 3 and 6, what is the length of the hypotenuse?
Answers
Answer:
Length of the hypotenuse = 3√5 units
Step-by-step explanation:
Given:
Right triangle sides
a = 3
b = 6
Find:
Length of the hypotenuse
Computation:
Length of the hypotenuse = √a² + b²
Length of the hypotenuse = √3² + 6²
Length of the hypotenuse = √9 + 36
Length of the hypotenuse = √45
Length of the hypotenuse = 3√5 units
what is the measure of E
Answers
Answer:
The measure of angle E is:
m∠E = 80°
Step-by-step explanation:
Given
The triangle ΔDEF
It is stated that DE=EF and G is the midpoint of EF.
It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.
Given
m∠GDE = 10°
As the right-angle triangle, ΔDEG lies at the right-angle G.
So, m∠DGE = 90°
as
m∠GDE = 10°
m∠DGE = 90°
m∠E = ?
We know that the sum of angles of a triangle is 180°.
m∠GDE + m∠DGE + m∠E = 180°
10° + 90° + m∠E = 180°
100 + m∠E = 180°
m∠E = 180° - 100
m∠E = 80°
Therefore,
The measure of angle E is: m∠E = 80°

Yoshua borrowed $8,000 from his credit union over 9 months. He pays a simple interest of
9%. What is the total amount of money he will owe the bank?
Answers
Answer:
[tex]\boxed{\blue{\sf He\ will \ owe \ \$ 8540 .}}[/tex]
Step-by-step explanation:
According to Question , Yoshua borrowed $8,000 from his credit union over 9 months. He pays a simple interest of 9%. And we are required to find the total amount of money he will owe the bank .
So , we know the formula of Simple Interest as ,
[tex]\qquad\boxed{\red{\bf SI =\dfrac{P\times R\times T}{100}}}[/tex]
As ,per the data in Question ,
Amount = $ 8,000Time = 9 monthsRate of Interst = 9% .[tex]\implies SI = =\dfrac{P\times R\times T}{100} \\\\\implies SI =\dfrac{\$ 8000 \times \dfrac{9}{12}\times 9 }{100} \\\\\implies SI = \dfrac{\$ 8000 \times 9 \times 9 }{12\times 100 }\\\\\boxed{\pink{\bf \implies Simple\: Interst = \$ 540 }}[/tex]
Hence the Simple Interest is $ 540.
And , we know that Amount is ,
[tex]\qquad\boxed{\red{\bf Amount = SI + Principal}}[/tex]
[tex]\implies Amount = Principal + SI \\\\ \implies Amount = \$ 8000 + \$ 540 \\\\\boxed{\orange{\bf \implies Amount= \$ 8540 }}[/tex]
Hence he will owe $ 85400.

What is x
Answers
Answer:

Step-by-step explanation:
Final Answer:
x = 3
Solution:
equation: -2x + 17 = 11
Step 1: subtract 17 in both sides
-2x + 17 = 11
-2x + 17 - 17 = 11 - 17
-2x = 11 - 7 (solve for -2x: 11 - 7)
-2x = -6
Step 2: divide -2 in both sides then solve for x.
-2x = -6
