angle efg and angle gfh are a linear pair, the measure of angle efg equals 4n+20, and measure of angle gfh equals 3n+13. what are the measures of angle efg and angle gfh?
Answer:
∠EFG=104° and ∠GFH=76°
Step-by-step explanation:
Given information:∠EFG = (4n+20)°, ∠GFH = (3n+13)° and ∠EFG and ∠GFH are a linear pair.
If two angles are a linear pair, then the sum of those angles is 180°.
It is given that ∠EFG and ∠GFH are a linear pair.
[tex]\angle EFG+\angle GFH=180^{\circ}[/tex]
Substitute the given values.
[tex](4n+20)+(3n+13)=180[/tex]
Combined like terms.
[tex](4n+3n)+(20+13)=180[/tex]
[tex]7n+33=180[/tex]
Subtract 33 from both sides.
[tex]7n+33-33=180-33[/tex]
[tex]7n=147[/tex]
Divide both sides by 7.
[tex]n=21[/tex]
The value of n is 21.
[tex]\angle EFG=4n+20=4(21)+20=104^{\circ}[/tex]
[tex]\angle GFH=3n+13=3(21)+13=76^{\circ}[/tex]
Therefore, the measure of ∠EFG and ∠GFH are 104° and 76° respectively.

1. A square has the side measurement of s= 2 3/2,
Using the formula A=s^2, find the area of the square.
2 3/2 = 3 1/2 ( 3/2 = 1 1/2 + 2 = 3 1/2)
so area = 3 1/2 ^2
3 1/2 x 3 1/2 = 12 1/4
Area = 12 1/4

A wheel makes 20 revolutions per minute. Find the angular velocity.
10π rad/min
20π rad/min
40π rad/min
Answer:
Angular velocity of a wheel which makes 20 revolutions per minute is 40π rad/min
Step-by-step explanation:
Angular velocity, ω = 2πf , where f is the frequency.
Here frequency, f = 20 revolutions per minute
Substituting frequency value in angular velocity equation,
Angular velocity, ω = 2πf = 2 x π x 20 = 40π rad/min
So angular velocity of a wheel which makes 20 revolutions per minute is 40π rad/min

A car travels at an average speed of 64 miles per hour. how many miles does it travel in 4 hours and 45 minutes?
Final answer:
The car travels 304 miles in 4 hours and 45 minutes at an average speed of 64 miles per hour.
Explanation:
To find the distance the car travels in 4 hours and 45 minutes, we need to convert the time to hours and minutes. There are 60 minutes in an hour, so 45 minutes is equal to 45/60 = 0.75 hours. Therefore, the total time is 4 + 0.75 = 4.75 hours.
To calculate the distance, we can use the formula:
Distance = Speed x Time
Given that the average speed is 64 miles per hour and the time is 4.75 hours, we can plug these values into the formula:
Distance = 64 mph x 4.75 hours = 304 miles.
If y varies directly as x and y is 18 when x is 5 which expression can be used to find the value of y when x is 11?
Answer:
The value of y is [tex]\frac{198}{5}[/tex] or 39.6.
Step-by-step explanation:
It is given that y varies directly as x and y. It means y is directly proportional to x.
[tex]y\propto x[/tex]
[tex]y=kx[/tex] .... (1)
where, k is constant of proportionality.
It is given that y is 18 when x is 5.
Substitute y=18 and x=5 in equation (1).
[tex]18=k(5)[/tex]
Divide both sides by 5.
[tex]\frac{18}{5}=k[/tex]
The value of k is [tex]\frac{18}{5}[/tex]. So, the relation between x and y is
[tex]y=\frac{18}{5}x[/tex] .... (2)
We need to find the value of y when x=11.
[tex]y=\frac{18}{5}(11)[/tex]
[tex]y=\frac{198}{5}[/tex]
[tex]y=39.6[/tex]
Therefore the value of y is [tex]\frac{198}{5}[/tex] or 39.6.

Reaner Recycling shreds 7/8 ton of aluminum each day.The machines can shred 1/24 ton aluminum per cycle.How many cycles will be needed to shred the aluminum?
plz help I don't get it
Answer:
21.
Step-by-step explanation:
We have been given that Reaner Recycling shreds 7/8 ton of aluminum each day.The machines can shred 1/24 ton aluminum per cycle.
To find the number of cycles needed to shred the aluminum, we will divide amount of aluminium by 1/24 as:
[tex]\text{Number of cycles}=\frac{7}{8}\div \frac{1}{24}[/tex]
Convert into multiplication problem by flipping the 2nd fraction:
[tex]\text{Number of cycles}=\frac{7}{8}\times \frac{24}{1}[/tex]
[tex]\text{Number of cycles}=\frac{7}{1}\times \frac{3}{1}[/tex]
[tex]\text{Number of cycles}=7\times 3[/tex]
[tex]\text{Number of cycles}=21[/tex]
Therefore, 21 cycles will be needed to shred the aluminum.

The number of timeshare condos available at sunset beach is 3/5 the number of timeshare condos available at playa del mar. if the total number of timeshare condos available at the two beaches combined is 240, what is the difference between the number of condos available at sunset beach and the number of condos available at playa del mar?
To find the difference between the number of condos available at Sunset Beach and Playa Del Mar, we need to set up an equation and solve for the unknown. The number of timeshare condos available at Sunset Beach is 3/5 of the number available at Playa Del Mar. By solving the equation, we find that the difference is 60 condos.
Explanation:To solve this problem, we can set up an equation. Let's say the number of timeshare condos available at Playa Del Mar is x. According to the question, the number of condos available at Sunset Beach is 3/5 of x, or 3/5x.
So, the total number of condos available at both beaches is x + 3/5x = 240. We can combine the like terms to get 8/5x = 240.
To solve for x, we divide both sides of the equation by 8/5, which is the same as multiplying by its reciprocal, 5/8. Simplifying, we get x = 240 * 5/8 = 150.
Therefore, the number of condos available at Sunset Beach is 3/5 * 150 = 90, and the difference between the number of condos available at Sunset Beach and Playa Del Mar is 150 - 90 = 60.

Which is an equivalent form of the equation 4x-y= 14
Answer:
y = 4x - 14 is equivalent from of y = 4x - 14.
Step-by-step explanation:
Given : 4x-y= 14
To find : Which is an equivalent form of the equation.
Solution : We have given 4x - y = 14.
We can write it in slope intercept form y = mx + b
Where, m = slope , b = y intercept.
4x - y = 14.
On subtracting both sides by 4x
- y= -4x + 14.
On dividing both sides by -1.
y = 4x - 14.
Therefore, y = 4x - 14 is equivalent from of y = 4x - 14.
