Answer:
50
Step-by-step explanation:
Answer:
50 seconds
Step-by-step explanation:
If I read this correctly the 50 seconds is 5/6 of a minute.
First we know there are 60 seconds to a minute. 60 can be divided by 6 to get 10 or we can just divide 60 by 10 to get the denominator (keep in mind 1/6 is worth 10 seconds) you can then multiply the numerator (5) by 10 to get 50 out of 60 seconds or 5/6 of a minute

Step-by-step explanation:
Given points are:
P(-8,5) and Q(-2,1)
Slope is the steepness of a straight line.
We will find slope of PQ
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{1-5}{-2-(-8)\\m=\frac{-4}{-2+8}\\m=\frac{-4}{6}\\m=\frac{-2}{3}[/tex]
The product of slopes of two perpendicular lines is equal to -1.
Let,
x be the slope of other line.
m.x = -1
[tex]\frac{-2}{3}x=-1\\x=\frac{3}{2}[/tex]
Therefore,
The slope of a line perpendicular to the line PQ is [tex]\frac{3}{2}[/tex].
Hence,
Option D: [tex]\frac{3}{2}[/tex] is the correct answer.

A red hot air balloon is at an altitude of 260 feet above the ground. It is descending at a rate of 9 feet per minute. A green hot air balloon is at an altitude of 75 feet and is ascending at a rate of 7 feet per minute. Which inequality represents the number of minutes it will take for the green hot air balloon to have a greater altitude than the red hot air balloon?
Answer:
To solve this problem you must follow the steps below:
1. The problem says that:
- The hot air balloon is at an altitude of 240 feet.
- It descends at 30 feet per minute.
2. Therefore, you have:
x: the time in minutes.
y: the altitute in feet.
3. Keeping all this information on mind, you can write the following equation:
y=240-30x
4. Therefore, as you can see, the answer is:
y=240-30x
Step-by-step explanation: Hope this helps plz mark brainliest

When a sprinkler is installed in the ground, the spray of water goes up and falls in the pattern of a parabola. The height, in inches, of a spray of water is given by the equation ℎ()=160−162 where is the number of feet away from the sprinkler head the spray is. What is the height of the spray 2 feet away from the sprinkler head?
Answer:
96feet
Step-by-step explanation:
Given the height, in inches, of a spray of water is given by the equation ℎ(x)=160−16x^2
x is the number of feet away from the sprinkler head the spray
To get the height of the spray 2 feet away from the sprinkler head, we will simply substitute x =2 into the function and et the height h as shown;
From the equation
ℎ(x)=160−16x^2
h(2) = 160-16(2)²
h(2) = 160-16(4)
h(2) = 160-64
h(2) = 96feet
Hence the height will be 96feet if the spray is 2feet away from the sprinklers head
Which equation shows how to use equivalent fractions to evaluate 5/8 - 3/10
Answer:
I don't know the options, but you would find the lowest common denominator as possible, in this case it's 40. so, you figure out how you get from the original denominator to the common one, and then do the exact same thing to the numerators.
[tex]\frac{5}{8} =\frac{25}{40}[/tex] and [tex]\frac{3}{10} = \frac{12}{40}[/tex]
and then take the two new fractions and subtract the numerators to get what the answer is:
[tex]\frac{25}{40} - \frac{12}{40} = \frac{13}{40}[/tex]= 0.325
normally you would simplify, but this fraction is already in it's simplest form. so you could convert to a decimal, but only if the directions say to.
Each vertical cross-section of the triangular prism shown below is an isosceles triangle.
What is the slant height, s, of the triangular prism?
Round your answer to the nearest tenth.
The slant height of the triangular prism is 5.4
Pythagoras theoremPythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given by:
Hypotenuse² = Opposite² + Adjacent²
From the triangular prism, the right angled triangle has sides s, 5 and 2(4/2), hence:

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be A
The value of A is
2x + 3y = -2 be equation (1)
Let the second equation be B
The value of B is
3x - 6y = 18 be equation (2)
Now , on simplifying the equation , we get
Multiply equation (1) by 3 , we get
6x + 9y = -6 be equation (3)
Multiply equation (2) by 2 , we get
6x - 12y = 36 be equation (4)
Subtracting equations (3) and equation (4) , we get
21y = -42
Divide by 21 on both sides of the equation , we get
y = -2
Substitute the value of y in equation (1) , we get
2x + 3 ( -2 ) = -2
2x - 6 = -2
Adding 6 on both sides of the equation , we get
2x = 4
Divide by 2 on both sides of the equation , we get
x = 2
Therefore , the value of x and y is 2 and -2 respectively
Hence , the solutions to the equations is x = 2 and y = -2

F(x)=4x+2 and g(x)=4(x−9)+2. What transformation occurs from function f to function g? a translation 9 units right a horizontal compression by a factor of 9 a horizontal stretch by a factor of 9 a translation 9 units down
Answer:
A translation 9 units right
Step-by-step explanation:
Given
[tex]f(x) = 4x + 2[/tex]
[tex]g(x) = 4(x -9)+ 2[/tex]
Required
Translation of f(x) to g(x)
To do this, we take the options one after the other.
A translation 9 units right
When an original function f(x) is translated to the right by h points, the resulting function g(x) is
[tex]g(x) = f(x - h)[/tex]
So, we have that:
[tex]f(x) = 4x + 2[/tex]
When translated to the right by 9 points,
[tex]g(x) = 4(x - 9) + 2[/tex]
Hence, option A answers the question

2 - (3x – 4) = 2x – 9
Answer:
2 - (3x – 4) = 2x – 9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2−(3x−4)=2x−9
2+−1(3x−4)=2x−9(Distribute the Negative Sign)
2+−1(3x)+(−1)(−4)=2x−9
2+−3x+4=2x−9
2+−3x+4=2x+−9
(−3x)+(2+4)=2x−9(Combine Like Terms)
−3x+6=2x−9
−3x+6=2x−9
Step 2: Subtract 2x from both sides.
−3x+6−2x=2x−9−2x
−5x+6=−9
Step 3: Subtract 6 from both sides.
−5x+6−6=−9−6
−5x=−15
Step 4: Divide both sides by -5.
−5x
−5
= −15
−5
x=3
