Answer: 53°
Step-by-step explanation:
3x - 4 + 3x + 6 + 4x - 12 = 180
10x - 10 = 180
Add 10 to both sides
10x = 190
Divide both sides by 10
x = 19
3x - 4
3 (19) - 4 = 57 - 4
= 53
3x + 6
3 (19) + 6 = 57 + 6
= 63
4x - 12
4 (19) - 12 = 76 - 12
= 64
The smallest angle is 53°
Answer:
63°

what is 4x ^2 + 20x in square to form a perfect square trinomial
25/5
Step-by-step explanation:
first make the coefficient of x alone... So that you should take the 4 out... then you get 4times x squared + 5x then you should didvide the x term by 2(always) and then you get 5/2...So then the third term or the constant is tye square of that..
Can u please help me
Answer:
P=p1+p2+p3+p4
P1=4*a=4*8=24
P2=a+b+c=6+10+8=24

P=24+24+60+60=160cm
The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y.
Answer:
If you're trying to find the measurement of angle z then it'd be 2x degrees, since its twice that of angle y, which is x degrees

How would you find the percent of discount if the sale price is $61.75 and the original price is $95
Answer:
Sale Price = $61.75 (answer). This means the cost of the item to you is $61.75. You will pay $61.75 for a item with original price of $95 when discounted 35%. In this example, if you buy an item at $95 with 35% discount, you will pay 95 - 33.25 = 61.75 dollars.

what is the value of 2^-3 as a fraction
Answer:
1/8
Step-by-step explanation:
2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8

Draw fraction strips to add 1/4 and 1/6 Write an equation.
Answer:
fraction strips would just be;
1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.
The equation would be as follows:
1/4+1/6 = 3/12+2/12 = 5/12

A frog is at the bottom of a 25-foot well. Each day he climbs up
5 feet, and each night he slips down 2 feet. How many days will
it take the frog to reach the top of the well?
The frog reached the top on the
day.
Be prepared to explain how you got your answer.
Answer:
25/3
Step-by-step explanation:
In 1 day we have daytime and night time each 12 hrs
in the day time he climbs 5ft and at night he slips 2 ft
meaning he climbs a total of 3ft(5-2) each day
so to get the number of days he climbed uts 25ft /3 ft
Therefore he takes 25/3 days to reach the top
answer is approximately 8.33 days
Answer:
Day 8Step-by-step explanation:
Each day progress:
5 - 2 = 3 feetAfter 7 days
7*3 = 21 feetDay 8:

The number of views on a cat video and a dog video after they're uploaded are represented by the following tables:
Answer:
Cat video: exponential function
Dog video: linear function
Step-by-step explanation: I did it until I got it right.
The cat video is a exponential function and dog video is a linear function .
What is linear function?Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
What is exponential function?An exponential function is a mathematical function of the following form:
f ( x ) = . where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.
According to the question
The tables for
Cat video
Time(month) Views
0 50
5 313
10 1950
15 12210
20 76300
So, as we can observe that values of views are increasing rapidly which can only be possible if function is exponential .
Dog video
Time(days) Views
0 10
6 452
12 889
18 1330
24 1770
So, as we can observe that values of views are increasing in constant pace which can be possible if function is linear .
We can plot graph of both the tables to check for the function nature .
Hence, the cat video is a exponential function and dog video is a linear function .

Slope: 2/3
Step-by-step explanation:
A slope is rise over run. You first have to get two perfect points, which I got (1,2) and (4,4). The rise is how much does it goes up and the run it's how much it goes to the side. Since the line it's going up, it is positive. The rise is 2 and the run is 3.

A sphere is rolled between two sharp, parallel blades that are 77 centimeters apart. Both blades cut off a piece of the sphere cleanly, leaving two parallel circular faces with radii of 39 and 60 cm. What is the radius of the sphere?
Answer:
The radius of the sphere is approximately 62.71 cm
Step-by-step explanation:
The question relates to the definition of a sphere
The given parameters are;
The distance between the sharp parallel blades through which the sphere is rolled = 77 centimeters
The radii of the circular faces left by cutting the sphere with the blade = 39 cm and 60 cm
From the triangles formed by the cross-section of the sphere, we have;
AB ║ DE Given
∠A ≅ ∠E, ∠D ≅ ∠B Alternate angles
∠C ≅ ∠C by reflective property
∴ ΔABC ~ ΔDCE by Angle-Angle similarity theorem
CF/CG = AB/DE = 78/120 = 13/20
CF = CG × 13/20
CF + CG = 77
∴ CG × 13/20 + CG = 77
33·CG/20 = 77
∴ CG = 140/3
CF = 13/20 × CG = 13/20 × 140/3 = 91/3
CF = 91/3
The diameter of the sphere AE = AC + EC
By Pythagoras's theorem
AC = √(FA² + CF²) = √(39² + (91/3)²) = 13·√(130)/3
EC = √(CG² + GD²) = √((140/3)² + 60²) = 20·√(130)/3
∴ AE = AC + EC = 13·√(130)/3 + 20·√(130)/3 = 11·√(130)
The diameter, 'D', of the sphere, AE = 11·√(130)
The radius of the sphere = D/2 = 11·√(130)/2 ≈ 62.71 cm

Answer:
Jerry's weight is 36kg and tom's weight is 66kg
Step-by-step explanation:
According to the given condition:
Let,tom's weight =x
Jerry's weight=y
So,
X=2y-6 ---(1)
X+y=102-----(2)
Put value of x from eq 1 in 2
2y-6+y=102
3y-6=102
3y=102+6
3y=108
Y=108/3=36
Jerry's weight is 36.
Put value of y in eq 1
X= 2(36) -6
X=72-6
X=66
So, Tom's weight is 66kg

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?
Answer:
115.02 feet
Step-by-step explanation:
The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?
We solve this question using the Trigonometric function of tan
tan x = Opposite/Adjacent
x = Angle of depression = 72°
Opposite = Height of the tower = 354 feet
Adjacent = Distance of the airplane from the base of the tower = y
Hence,
tan 72 = 354/y
Cross Multiply
tan 72 × y = 354
y = 354/tan 72
y = 115.02157247 feet
Approximately = 115.02 feet
Therefore, the distance of the airplane from the base of the tower is 115.02 feet
