Answer:
67 degrees.
Step-by-step explanation:
The two quadrilaterals are congruent, with angle T corresponding to angle F, angle U corresponding to angle C, angle V corresponding to angle D, and angle W corresponding to angle E.
A quadrilateral's interior angles add to be 360 degrees.
x + 138 + 67 + 88 = 360
x + 293 = 360
x = 67
So, angle D is 67 degrees.

what is the measure of x? 68 degrees 70 degrees
Answer:
x = 138°
Step-by-step explanation:
Since the sum of all angles in a triangle is 180°, we find ∠BAC:
m∠BAC = 180 - (68 + 70) = 42°
Since ∠x and ∠BAC are Supplementary Angles, they add up to 180°:
180 - 42 = x
x = 138°
Answer:
138
Step-by-step explanation:
1. 68 + 70 = 138
2. 180 - 38 = 42
3. 180 - 42 = 138
4. X = 138

x=3.3
x=15.3
x=10
x=12
Answer:
The correct option is
x = 10
Step-by-step explanation:
in a circle Given that chord [tex]\overline {OP}[/tex] is congruent to [tex]\overline {QR}[/tex], we have;
Measured angle m∠RZQ is congruent to measured angle m∠PZO
Congruent chords are subtended by congruent angles at the center of the circle
Therefore we have;
4·x - 11 is equal to 2·x + 9
4·x - 2·x = 9 + 11
2·x = 20
x = 10
The value of the measured angles are;
4·x - 11 = 4×10 - 11 = 40 - 11 = 29°
The value of x is 10°.
Answer:
x=10
Step-by-step explanation:
4·x - 11 is equal to 2·x + 9
4·x - 2·x = 9 + 11
2·x = 20
x = 10
The value of the measured angles are;
4·x - 11 = 4×10 - 11 = 40 - 11 = 29°
The value of x is 10°

WHAT IS THE EQUATION: Tamara is going with her class on a three-day field trip. the cost of the trip is $76 per student. the price includes $14 per night for two nights in a hotel. Tamara will also receive six meal tickets. Each meal ticket costs the same amount. how much does each meal ticket cost?
Answer:
$8
Step-by-step explanation:
The cost is $76 per student so first we subtract the cost of two nights at the hotel which together is $28.
$76 - $28 =$48
Now the money left is $48 which is supposed to be used for the six meal tickets. so, to find the cost of 1 meal ticket we just have to divide the remaining amount of money by 6.
$48 ÷ 6 = $8
Answer:
$8

Definition:A sailboat set a course of N 25° E from a small port along a shoreline that runs north and south. Sometime later the boat overturned and the crew sent out a distress call. They estimated that they were 12 miles away from the nearest harbor, which is 28 miles north of the port they had set sail from. If a rescue team leaves from the harbor, find all possible courses the team must follow in order to reach the overturned sailboat.
Answer:
S 75°E
S 55°E
Step-by-step explanation:
Take the law if sines of a triangle:
[tex] \frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC} [/tex]
Where,
a = 28 miles
B = 25°
b = 12 miles
First solve for A, using the law of sines:
[tex] \frac{a}{sinA} = \frac{b}{sinB} [/tex]
[tex] \frac{28}{sinA} = \frac{12}{sin25} [/tex]
Cross multiply:
[tex] 28 sin25 = 12 sinA [/tex]
[tex] 11.83 = 12 sinA [/tex]
[tex] Sin A = \frac{11.83}{12} [/tex]
[tex] Sin A = 0.986 [/tex]
[tex]A = sin^-^1(0.986)[/tex]
[tex] A = 80.44 degrees [/tex]
Since A = 80.44° find A supplement, A`:
A` = 180 - 80.44
A` = 99.56°
If A` + B < 180°, find C.
Thus,
A` + B = 99.56 + 25 = 124.56
We can see that A` + B < 180
Find C:
C = 180 - (80.44+25) = 74.56° ≈ 75°
C` = 180 - (99.56+25) = 55.44° ≈ 55°
Rewrite in bearing form:
S 75°E
S 55°E

Since it is just a single red x this is what it stands for
1/2g-4=2g-1/2g+4
does it have one solution or infinitely many solutions ? Why ?
Explanation:
2g - (1/2)g = (4/2)g - (1/2)g = (3/2)g
The original equation becomes (1/2)g-4 = (3/2)g+4
The slopes are 1/2 and 3/2 respectively. Since the slopes are different, the two lines cannot be parallel.
Since we don't have parallel lines, they intersect at exactly one point leading to exactly one solution.
Answer:
the first one- one solution
the second one- infinitely many solutions
Step-by-step explanation:
1/2g-4=2g-1/2g+42g-1/2g-1/2g= -4-4g= -8One solution as one intersection point

Flying against the wind, an airplane travels 7520 kilometers in 8 hours. Flying with the wind, the same plane travels 6500 kilometers in 5 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
Rate of plane in still air = 1120 km/h
Rate of wind = 180 km/h
Step-by-step explanation:
Let the rate (speed) of the plane in still air = u km/h
Let the rate (speed) of the wind = v km/h
Formula for speed is:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Given that against the wind, airplane travels 7520 km in 8 hours.
The speed against the wind will be slower so,
Against the wind, speed = (u -v ) km/h
Using above formula:
[tex](u-v) = \dfrac{7520}{8} km/h\\(u-v) = 940 km/h ..... (1)[/tex]
Given that with the wind, airplane travels 6500 km in 5 hours.
The speed with the wind will be faster so,
With the wind, speed = (u +v ) km/h
Using above formula:
[tex](u+v) = \dfrac{6520}{5} km/h\\(u+v) = 1300 km/h ..... (2)[/tex]
Adding (1) and (2) to solve for u and v:
[tex]2u = 2240\\\Rightarrow u = 1120\ km/h[/tex]
Putting u in (1):
[tex]1120-u=940\\\Rightarrow u = 180\ km/h[/tex]
So, the answers are:
Rate of plane in still air = 1120 km/h
Rate of wind = 180 km/h

Step-by-step explanation:
a.) Let x=0 and solve for y: y=0+4=4. Since we let x=0 the first number will be 0 and we found y to be 4, so our coordinates are (0,4)
b.) Let y=0 and solve for x: 0=x+4, x=-4. Since x=-4 our first number is -4, since y is 0 our second number is 0, so our coordinates are (-4,0)

Open the graphing tool, and compare the functions using the sliders. What can be said about the domain of
y= VX - kand the domain of y = VX + k?
Answer:
Therefore, domain of y = [tex]\sqrt{x-k}[/tex] ; Domain = [k, ∞)
Domain of y = [tex]\sqrt{x}+k[/tex] ; Domain = [0, ∞)
Step-by-step explanation:
Two functions are,
y = [tex]\sqrt{x-k}[/tex]
and y = [tex]\sqrt{x}-k[/tex]
Let the value of k = 1
Then we find the graph of the functions attached.
By analyzing these graphs,
y = [tex]\sqrt{x-1}[/tex] when shifted 1 unit right and 1 unit down we get a new function,
y = [tex]\sqrt{x}+1[/tex]
Therefore, domain of y = [tex]\sqrt{x-1}[/tex] ; Domain = [1, ∞)
Domain of y = [tex]\sqrt{x}+1[/tex] ; Domain = [0, ∞)
Similarly, domain of y = [tex]\sqrt{x-k}[/tex] ; Domain = [k, ∞)
And domain of y = √x + k ; Domain = [0, ∞)

Is (4,6) a solution to 5x+3y =-4
Answer:
False
Step-by-step explanation:
5x+3y =-4
Substitute the point into the equation and see if it is true
5(4) +3(6) = -4
20 +18 = -4
38 = -4
This is false so the point is not a solution
Answer:
No.
Step-by-step explanation:
5x + 3y = -4
For (4, 6) to be a solution, 4 must be put in for x and 6 for y and the solution must be -4.
(5 * 4) + (3 * 6) = 20 + 18 = 38
Since 38 is NOT equal to -4, (4, 6) is not a solution.

Question 4 A family has two cars. The first car has a fuel efficiency of miles per gallon of gas and the second has a fuel efficiency of miles per gallon of gas. During one particular week, the two cars went a combined total of miles, for a total gas consumption of gallons. How many gallons were consumed by each of the two cars that week
Complete question is;
A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During one particular week, the two cars went a combined total of 1850 miles, for a total gas consumption of 50 gallons. How many gallons were consumed by each of the two cars that week?
Answer:
Car 1 consumed 30 gallons of gas.
Car 2 consumed 20 gallons of gas.
Step-by-step explanation:
Let x be number gallons consumed by car 1
Let y be number of gallons consumed by car 2
We are told that total gas consumption of 50 gallons. Thus;
x + y = 50 - - - - - eq(1)
We are told that the first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas and they went a combined total of 1850 miles. Thus;
35x + 40y = 1850 - - - - eq2
Let's make y the subject in eq(1),
y = 50 - x - - - - eq(3)
Putting 50 - x for y in eq 2 gives;
35x + 40(50-x) = 1850
35x + 2000 - 40x = 1850
-5x + 2000 = 1850
-5x = -150
x = 150/5
x = 30 gallons
Substitute 30 for x into eq 3,we have;
y = 50 - 30
y = 20 gallons
Thus;
Car 1 consumed 30 gallons of gas.
Car 2 consumed 20 gallons of gas.
