Aaliyah wants to download 50 songs on her phone, but her phone has room for only a third of the songs. How many songs can she download?
Answer:
16 songs.
Step-by-step explanation:
If Aaliyah has 50 songs, but her phone can only hold a third of those songs, to solve this problem, we will have to find a third of 50.
Divide 50 into 3:
[tex]50[/tex] ÷ [tex]3[/tex]
[tex]=16.6666...[/tex]
As this decimal does not terminate, we'll have to round down to [tex]16[/tex] since we cannot have a portion of the song downloaded.
Therefore, Aaliyah can download 16 songs on her phone.
Open the parallel lines translation application. The right set of parallel lines is a translation right 10 units of the left set of parallel lines. Drag the left set of parallel lines and try to move them onto the right set. Are the two sets of parallel lines the same? What does this mean about how parallel lines change when you translate them?
Answer:
when translation appears on the axises for any shape or line, the same line would not compare each other. Just like the parallel lines that I used. These two lines are not compared to each other.

2x - 5= 5x + 7 linear equations
Answer:
-4 =x
Step-by-step explanation:
2x - 5= 5x + 7
Subtract 2x from each side
2x-2x - 5= 5x-2x + 7
-5 = 3x+7
Subtract 7 from each side
-5-7 = 3x+7-7
-12 = 3x
Divide by 3
-12/3 = 3x/3

The graph represents how kyren spent her allowance this week. If her allowance was $20, how much did she spend on the spirit shirt
Answer:8 Dollars
Step-by-step explanation: The whole is 100 so you add 50 and 10 together which is the lunch and candy which equals 60 then you subtract the whole number 100 by 60 giving you 40 which is the percentage of 20 that was spent on the spirit shirt.And the way I do it is 10 percent of 20 is 2 so times 2 by 4 which gives you 8 dollars.

what is the area and perimeter of this triangle
Answer:
A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)
Step-by-step explanation:
the area of a triangle is half of its base times height.
the base and the height must be perpendicular to each other; so they would be 56 and 73.
56(73)/2=2044
the perimeter is the sum of all the sides
73+56+92=221
The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.
To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.
Area of a right-angled triangle:
The area of a triangle can be found using the formula:
A = (1/2) x base x height
Plugging these values into the formula, we get:
A = (1/2) x 73 cm x 56 cm
A = 2044 cm²
Therefore, the area of the right-angled triangle is 2044 cm².
Perimeter of a right-angled triangle:
The perimeter of a triangle is the sum of all its sides.
In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.
Perimeter = 73 cm + 92 cm + 56 cm
Perimeter = 221 cm
Therefore, the perimeter of the right-angled triangle is 221 cm.

i don't understand how to solve this 136 - (-128.6) =
Answer:
264.6
Step-by-step explanation:
Answer:
264.6
Step-by-step explanation:
ok first of all if you are subtracting a negative the it becomes a positive
136 - (-128.6)
136 + 128.6
this is what goes on in my head you don't have to do it this way but i do
100 + 100 = 200
30 + 20 = 50
6 + 8.6 = 14.6
200 + 50 + 14.6 = 264.6
The larger number is five more than the smaller number. Four more than three times the
smaller number is twice the larger number. Find both numbers.
Answer:
Larger number = 11
Smaller number = 6
Step-by-step explanation:
Let the larger number = x
Let the smaller number = y
x - y = 5
3y + 4 = 2x Subtract 2x
-2x + 3y + 4 = 0
===========
Multiply the first equation by 2. Write the second equation underneath
2x - 2y = 10
-2x + 3y + 4 = 0
add
y + 4 = 10
Subtract from both sides
y = 10 - 4
y = 6
==========
x - y = 5
x - 6 = 5 Add 6 to both sides
x = 5 + 6
x = 11
Answer:
6 and 11Step-by-step explanation:
x ← the smaller number
x+5 ← five more than the smaller number - the larger number
3x ← three times the smaller number
3x+4 ← four more than three times the smaller number
2(x+5) ← twice the larger number
3x + 4 = 2(x + 5)
3x + 4 = 2x + 10
-4 -4
3x = 2x + 6
-2x -2x
x = 6
x+5 = 6 + 5 = 11
Check: 3•6 + 4 = 22; 22:2 = 11
Over the next 15 months you have to read at least 75 books. You have to read x books per month. The inequality "75 is greater than or equal to 15x" represents this situation. Solve the inequality to find the number of books you have to read per month.
Answer:
you have to read at least 5 books per month (on average)
Step-by-step explanation:
The given inequality is incorrect. "At least 75" means "greater than or equal to 75", so the inequality should be ...
15x ≥ 75
x ≥ 5 . . . . . . divide by 15
You have to read at least 5 books per month.
Which functions are symmetric with respect to the origin?
y = arcsinx and y = arccosx
y = arccosx and y = arctanx
y = arctanx and y = arccotx
y = arcsinx and y = arctanx
Answer:
The correct option is;
y = arcsinx and y = arctanx
Step-by-step explanation:
The given options are;
1) y = arcsinx and y = arccosx
Here, we have at the origin, where x = 0, arccosx ≈ 1.57 while arcsinx = 0
Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin
2) y = arccosxy and y = arctanx
Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical
3) y = arctanx and y = arccotx
Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical
4) y = arcsinx and y = arctanx
Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.
The function are symmetric with respect to the origin is y = arcsinx and y = arctanx and this can be determined by using the trigonometric property.
The following steps can be used in order to determine which functions are symmetric with respect to the origin:
Step 1 - Check all the options given in order to determine which functions are symmetric with respect to the origin.
Step 2 - Substitute (x = 0) in option a), that is:
[tex]\rm y = sin^{-1}(0)=0[/tex]
[tex]\rm y = cos^{-1}(0)=1.57[/tex]
Step 3 - Substitute (x = 0) in option b), that is:
[tex]\rm y = cos^{-1}(0)=1.57[/tex]
[tex]\rm y = tan^{-1}(0)=0[/tex]
Step 4 - Substitute (x = 0) in option c), that is:
[tex]\rm y = tan^{-1}(0)=0[/tex]
[tex]\rm y = cot^{-1}(0)=1.57[/tex]
Step 5 - Substitute (x = 0) in option d), that is:
[tex]\rm y = tan^{-1}(0)=0[/tex]
[tex]\rm y = sin^{-1}(0)=0[/tex]

Erik drives 19.2 miles in 16 minutes.
He passes a sign which gives the speed limit as 65 mph.
By how much, in mph, did Erik's average speed exceed the speed limit?
The average speed exceeding the speed limit is mathematically given as
6.91 kilometers per hour
This is further explained below.
What is the average speed exceeding the speed limit?Let's assume that Erik maintains a steady pace during the whole trip.
Therefore, the following equation of motion may be used to compute the speed, which is expressed in terms of miles per hour:
Where: miles is the unit of measurement for distance.
t stands for time, which is measured in hours.
Kindly take into account that one hour is comprised of sixty minutes. If we assume so, then we can calculate Erik's speed as follows:
[tex]\begin{aligned}&v=\frac{19.2 m i}{0.267 h} \\\\&v=71.910 \frac{m i}{h}\end{aligned}[/tex]
In conclusion, That is 6.91 kilometers per hour faster than the allowed speed limit.
