Answer:
x=41
Step-by-step explanation:
supplementary angles add to 180
3x + (2x-25) = 180
5x = 205
x= 41
angle1 3x41 = 123
angle 2 (2x41) -25 = 57
123 +57 = 180

4x - 35x - 3Step-by-step explanation:
m∠BEC = (2x+3)when x = 30°m∠BEC → (2(30)+3) → 63°m∠AED = (360-2(63))/2
m∠AED = 117°
solve for first:
(4x - 3)
(4(30) - 3)
117° ............matches.
solve for third:
5x - 33
5(30) - 33
117° ........matches
Hence the first option and third is correct. rest two are wrong.

Answer:
Here,L=20m , a=109sq.m
let,breadth be x
we have a=l×b
or,100=20×x
or,100/20=x
or,5=x
hence,the breadth of the hall is 5m.answer
Answer:
5m²
Step-by-step explanation:
To find the breadth of a rectangle (the hallwa) simply Divide the area by the length
So . .

What is the average speed of a car that travels 440 km in 15.4 hours?
A car travels 440km in 15.4 hours -> In 1 hour, the car travel 1/(15.4) the distance.
So in an hour, the car travel : 440 x 1/(15.4) = 28.5714285714... (round to 29)
So, the average speed of the car is approximately 29 km/h

[tex]\frac{7.5*10^{12} }{2.5*10^{4} } =\frac{7.5}{2.5} *\frac{10^{12} }{10^{4} } = 3 * 10^{12 - 4} = 3*10^8[/tex]

[tex]3 \times 10^8[/tex]
=================================================
Explanation:
Divide 7.5 over 2.5 to get 3
Dividing the other terms means we subtract the exponents using this rule
[tex]\frac{a^b}{a^c} = a^{b-c}[/tex]
So,
[tex]\frac{10^{12}}{10^4} = 10^{12-4} = 10^8[/tex]
Overall,
[tex]\frac{7.5 \times 10^{12}}{2.5 \times 10^4} = 3 \times 10^8[/tex] which points to choice C

State if each triangle is a right triangle.
Answer:
Yes.
Step-by-step explanation:
To find if a triangle is a right triangle or not, we use the Pythagorean theorem. The Pythagorean theorem states that [tex]a^{2} + b^{2} = c^{2}[/tex].
a and b are the triangle legs. The c is the hypotenuse of the triangle.
Now, to find if a triangle is a right triangle, we plug in 9 for a and b and 9root2 for c.
[tex]9^{2} + 9^{2} = (9\sqrt{2})^{2}[/tex]
81 + 81 = 81 * 2
162 = 162
So the given triangle, is indeed a right triangle.
a. The measure of LKM is 35º, the measure of KLM is 72.5° and the measure of KLM is unknown.
b. The equation 35 + 72.5 + x = 180 can be used to find the measure of KLM.
c. The measure of ZKLM is 35º.
Correct the false statement:
Answer:
Step-by-step explanation:
B. True
A. Is a bit ambiguous. KLM technically speaking, I suppose, is sort of true, but KLM can be found. Enter true.
C. is False
35 + 72.5 + x = 180 Combine the terms on the left
107.5 +x = 180 Subtract 107.5 from both sides.
107.5 107.5
x = 72.5
Let 1995 correspond to x=0. Let b be the ratio between the population in 1995 and 1996. Determine an exponential function of the form y=a(b)^x to represent the population symbolically. Round to 3 decimal places.
The table is an illustration of an exponential function
The equation of the table is [tex]y = 148 * 0.997^x[/tex]
How to determine the equation of the tableGiven that 1995 corresponds to x = 0, then
The initial value (a) of the function is:
a = 148.0
The equation of the function is:
[tex]y = ab^x[/tex]
When x= 1, we have:
[tex]147.6 = ab^1[/tex]
[tex]147.6 = ab[/tex]
This gives
[tex]147.6 = 148b[/tex]
Divide both sides by 148
[tex]b = 0.997[/tex]
Hence, the equation of the table is:
[tex]y = 148 * 0.997^x[/tex]

Harrison's Butcher Shop sells 1/3 pounds of bee

for a cookout, how much would the beef cost?
Setup a proportion to answer the problem.
$27.50
$7.50
$15.00
$22.50
1.50 * 3 = 4.5 (cost 1 pound)
4.5 * 5 = 22.5 (total cost)
The cost of 5 pounds of beef for a cookout given the cost of 1/3 pounds is $22.50
How to find the cost of beef1/3 pounds = $1.505 pounds = $xEquate the ratio
1/3 : 1.50 = 5 : x
1/3 ÷ 1.50 = 5/x

The first step of finding the percent tip, we must find how much tip she paid:
Tip = $38.61 - $33 = $5.61
To find the percent tip, we must divide the tip amount by the amount she paid before the tip
$5.61 / $33 = 0.17 --> 17%
Thus the percent tip is 17%

find (f-g)(x) for f(x)=x^2+8x and g(x)=3x-5
Answer:
(f-g)(x)= f(x) - g(x)
= x^2 + 8x - ( 3x - 5)
= x^2 + 8x - 3x + 5
= x^2 + 5x + 5
(f-g)(x)= x^2 + 5x + 5
The required expression of (f-g)(x) = x^2+5x+5.
f(x) = X^2+8x; g(x) = 3x - 5
(f-g)(x) to determine.
It is defined as the number of composition, constitute the whole.
Here, (f-g)(x)= f(x)-g(x)
= x^2+8x-3x+5
= x^2 + 5x + 5
Thus, the required expression of (f-g)(x) = x^2+5x+5.
