Answer:
y=11/3
Step-by-step explanation:
39 = 6(1) + 9y
39 = 6 + 9y
39 - 6 = 9y
33 = 9y
9y = 33/9
y = 11/3
Answer:
y = 11/3
Step-by-step explanation:
Sometimes it's just how things are written that makes them seem super hard.
R = 6x + 9y is the equation, and then they say what to sub in for x and R. So now we have:
39 = 6(1) + 9y
39 = 6 + 9y
subtract 6 from both sides
33 = 9y
y = 33/9, simplified to 11/3
The sum of two numbers is 24. The second number minus the first number equals 2.
Let x represent the first number. Let y represent the second number.
Write a system of equations to represent the situation.
First sentence: First Equation:
Second Sentence: Second Equation:
*Do not include spaces in your equations.
Part 2: Find the numbers. ( , )
Answer:
(11, 13)
Step-by-step explanation:
First Equation: x+y=24
Second Equation: y=x+2
x + (x + 2) = 24
2x + 2 - 2 = 24 - 2
2x/2 = 22/2
x = 11
y = (11) + 2
y = 13
Therefore, the solution to the system is (11, 13)

Find the area of the shaded region to the nearest tenth.
Answer:
Shaded region is 18.3 units²
Step-by-step explanation:
First find the area of the white triangle. The base and height of this triangle are both 8. Thus, the area of the triangle is (1/2)(base)(height), or 32 units.
Next, find the area of the whole circle. It is πr², which in this case comes
out to π(8 units)² = 64π units². Realize that (1/4) of this, or 16π units², is the area of the quarter circle that contains the triangle.
To find the shaded area, take the area of the quarter circle (16 π units²) and subtract the area of the triangle (32 units²).
16π units² - 32 units² = 18.3 units²
Shaded region is 18.3 units²

Answer:
19.0 cm
Step-by-step explanation:
a^2+b^2=c^2
1^2+b^2=19^2
1+b^2=361
(subtract one from both sides)
b^2=360
(now square root to get rid of the ^2)
[tex]\sqrt{b^2}[/tex]=[tex]\sqrt{360}[/tex]
b=18.97 rounded to the tenths place is 19.0
Answer:
The length of the other leg is 19 cm (rounded to the nearest tenth).
Step-by-step explanation:
In order to solve this, we need to know the Pythagoras theorem which states that...
[tex]c^{2} = a^{2} +b^{2}[/tex] (Where c is the length of the hypotenuse and a and b are the lengths of the legs)
Now just substitute the values to find the length of the other leg, and we get...
[tex]c^{2} = a^{2} +b^{2}\\19^{2} = 1^{2} + b^{2} \\b^{2} = 19^{2} - 1^{2} \\b^{2} = 361 - 1\\b^{2} = 360\\b = \sqrt{360} \\[/tex]
b ≅ 19
Therefore the length of the other leg is around 19 cm.

A triangle has sides with lengths of 20 meters, 21 meters, and 29 meters. Is it a right triangle?
Answer:
Yes, the sides form a right triangle.
Step-by-step explanation:
Pythagorean Theorem:
a² + b² = c²
↓
20² + 21² = 29²
║a² = 20² = 400
║b² = 21² = 441
║c² = 29² = 841
↓
400 + 441 = 841
║This equation is true.
↓
Yes, the sides form a right triangle.

An airplane's altitude in feet during its descent can be found using the equation y=-150x + 30,500. After new government regulations become law, the descent isnow modeled by the equation y=-150x + 30,000. Which statement describes this change?
The airplane starts its descent from an altitude 500 feet lower.
The airplane descends 500 feet per horizontal mile slower.
The airplane descends 500 feet per horizontal mile faster.
The airplane starts its descent from an altitude of 500 feet.
Answer:
The airplane would starts its descent from an altitude 500 feet lower.
Step-by-step explanation:
The x-axis is horizontal and the y-axis is vertical (altitude). It would be 500 feet lower because they took 500 away from the 30,000.

1. if m<b = 60 what is AB
2. if m<b =45 what is the perimeter of the trapezoid.
Answer:....
Step-by-step explanation:
first we need to find the base of the triangle, so the total is 20, they also give us 12, so we subtract 20-12=8 now divide. 8/2=4. Now we use the 4 and the 60. We use SOH-CAH-TOA, they give us the base now we need to find AB which is the hypotenuse. So we take out the TOA, and the 4 is the adjacent so we take out the SOH, we have CAH now, so we use cos. Now equation time....
[tex]cos60=\frac{4}{x}[/tex] since x is the bottom we switch [tex]\frac{4}{cos60}[/tex], which equals 8. AB=8.
Now to find the perimeter. We still use the 4 to find the hypotenuse so we can find the outside side. For this one they tell us to use 45, so now lets see what method we use. SOH-CAH-TOA. We need the hypotenuse and they give us the adjacent, so we use cos again. Now setting up the equation...
[tex]cos45=\frac{4}{x}[/tex] x is at the bottom again to we switch.
[tex]\frac{4}{cos45}[/tex] which equals to 5.657 or you can round it. Now we add everything.
20+12+5.657+5.657= 45.314 or you can round it to 45.

12 minutes for 5 songs =
minutes for 20 songs
Answer:
48
Step-by-step explanation:
5 songs would equal 12 minutes, right?
5 times what equals 20? It's 4, so you take 12 times 4 since there'd be 4 times as many songs. So, to listen to 20 songs it'd take 48 minutes.
