Answer:
-5/13<x<0
Step-by-step explanation:
5/x+6<-7
subtract 6 from both sides
5/x+6-6<-7-6
5/x<-13
since it is just like a normal equation with an equals sign you can still switch the -13 and x to get
-5/13<x<0
Hope that helps :)
. Two planes are 1620 miles apart and are traveling toward each other. One plane is traveling 120 mph
faster than the other plane. The planes meet in 1.5 hours. Find the speed of each plane.
Answer:
Step-by-step explanation:
let the speed of one plane=x mph
speed of other plane=x+120 mph
x×1.5+(x+120)×1.5=1620
(x+x+120)×1.5=1620
(2x+120)×1.5=1620
3x+180=1620
3x=1620-180
3x=1440
x=480
speed of one plane=480 mph
speed of second plane=480+120=600 mph
Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Which inequality represents the amount she can still spend this month and remain within her budget?
x greater-than 272
x less-than-or-equal-to 272
x less-than 272
x greater-than-or-equal-to 272
Answer:
1200-928 = 272 for the rest of the month Clarissa has to spend.
Step-by-step explanation:
So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over. Option 2 or B.

A boat can travel 423 miles on 47 gallons of gasoline. How much
gasoline will it need to go 108 miles?
Answer:
12
Step-by-step explanation:
i done the butterfly method
Answer:12
Step-by-step explanation:
423/47=108/x
Then we can cross-multiply and simplify, getting the X alone:
108*47=5076 423*x=423x
423x=5076
Divide to isolate:
x=5076/423
x=12

Find the mean of the data set: 573, 569, 566, 561, 566, 566, 568.
a. 566
b. 567
c. 561
d. 573
Answer:
b. 567
Step-by-step explanation:
All you have to do is add the whole set, then divide by how many numbers it is.
573+569+566+561+566+566+568= 3969
3969/7= 567
There is 7 numbers in the set, so you add the numbers then divide by 7.
Answer: B is definitely the correct answer because you add up all the numbers then just divide.

How much more did Leroy pay than Cora?
Answer:
Leroy paid 49.07 more than Cora.
Step-by-step explanation:
Let LeRoy's bill be x
Let Cora's bill be y
3*y - 8.59 = x (1)
x + y = 68.29 (2)
Substitute the value of x in (1) into the value of x in (2)
3y - 8.59 + y = 68.29 Combine the ys
4y - 8.59 = 68.29 Add 8.59 to both sides
+ 8.59 8.59
4y = 76.88 Divide by 4
4y/4 = 76.88/4
y = 19,22
x + y = 68.29 Substitute 19.22 for y
x + 19.22 = 68.29 Subtract 19.22 from both sides
- 19.22 -19.22
x = 49.07

Answer:
$5
Step-by-step explanation:
Set up a system of equations
let b be the cost of a bow
let w be the cost of a roll of wrapping paper
This means that
[tex]5b + w = 10\\b + w = 6[/tex]
Subtract the two equations
[tex]5b + w = 10\\- (b + w = 6)\\4b = 4\\b = 1[/tex]
Plug this into the equation b + w = 6
1 + w = 6
w = 5.
This means the cost of a bow is $1 and the cost of a roll of wrapping paper is $5.

Step-by-step explanation:
What are the ratios of sine, cosine, and tangent for angle Y? sin(Y) = StartFraction X Z Over X Y EndFraction; cos(Y) = StartFraction Y Z Over X Z EndFraction; tan(Y) = StartFraction Y Z Over X Y EndFraction sin(Y) = StartFraction X Y Over X Z EndFraction; cos(Y) = StartFraction X Z Over X Y EndFraction; tan(Y) = StartFraction Y Z Over X Z EndFraction sin(Y) = StartFraction X Z Over X Y EndFraction; cos(Y) = StartFraction Y Z Over X Y EndFraction; tan(Y) = StartFraction X Z Over Y Z EndFraction sin(Y) = StartFraction Y Z Over X Y EndFraction; cos(Y) = StartFraction X Z Over X Y EndFraction; tan(Y) = StartFraction X Z Over Y Z EndFraction
Answer:
[tex]\sin Y= \frac{XZ}{XY}[/tex]
[tex]\cos Y= \frac{YZ}{XY}[/tex]
[tex]\tan Y= \frac{XZ}{YZ}[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find [tex]\sin, \cos[/tex] and [tex]\tan[/tex] of angle Y
For angle Y:
[tex]Opposite = XZ[/tex]
[tex]Adjacent = YZ[/tex]
[tex]Hypotenuse = XY[/tex]
The [tex]\sin[/tex] of an angle is calculated as:
[tex]\sin\theta = \frac{Opposite}{Hypotenuse}[/tex]
So:
[tex]\sin Y= \frac{XZ}{XY}[/tex]
The [tex]\cos[/tex] of an angle is calculated as:
[tex]\cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]
So:
[tex]\cos Y= \frac{YZ}{XY}[/tex]
The [tex]\tan[/tex] of an angle is calculated as:
[tex]\tan\theta = \frac{Opposite}{Adjacent}[/tex]
So:
[tex]\tan Y= \frac{XZ}{YZ}[/tex]

The diameter of a circle is 6 m. Find its area to the nearest tenth.
Answer:
28.3 m^2
Step-by-step explanation:
The formula to find the area of a circle is πr^2
r = radius (half of the diameter) = 3
3^2 = 9 so the area is 9π m^2
Rounded to the nearest tenth this equals about 28.3 m^2.
