1/4 of what equals 6
Answer:
24
Step-by-step explanation:
1/4×6
4×6=24
=24
HOPE it HELPS you
Answer:
24
Step-by-step explanation:
[tex]\frac{1}{4}[/tex] of x = 6
x is the unknown value
[tex]\frac{1}{4}[/tex] × x = 6
1x = 6 × 4
x = 24
∴ [tex]\frac{1}{4}[/tex] of 24 equals to 6

Terrence leaves a $3 tip at a restaurant. If that tip is equal to 15% of his total bill, what is his total bill?
Answer:
$20
Step-by-step explanation:
To find the total bill, divide the tip amount by 0.15
3/0.15
= 20
So, his total bill was $20

In your own words, what is a radical expression?
Answer:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.

what you need to do is write an equation for each graph *ILL REALLY APRECIATE YOUR HELP*
Answer:
Download the app photomath and right your solution
First, you need to know what "m" and "b" represents.
"m" represents slope, and "b" represents the y intercept.
For the equation you can combine the information to get y = mx + b
To find "m" indentify points, and see how many you have to go up/down then left/right.
To find "b" since the graphis given see where the line crosses the y axis. (0, b)
1. m = -1, b = 3
y = -1x + 3
2. m = 1, b = -3
y = 1x -3
3. m = 3/1 or 3, b = 1
y = 3x + 1
4. m = -3/1 or -3, b = -3
y = -3x -3

A scientific calculator has 42 buttons. There are twice as many grey buttons as orange buttons. There are two more white buttons than grey buttons. There twice as many black buttons as white buttons. WRITE AN EQUATION TO CALCULATE HOW MANY BUTTONS OF EACH COLOUR THERE ARE. LET X REPRESENT THE NUMBER OF ORANGE BUTTONS.
Answer:
x + 2x + 2x + 2 + 4x + 4 = 42
Step-by-step explanation:
Let us assume the number of orange buttons be x
So, the grey buttons be 2x
The white buttons would be 2x + 2
And the black buttons be 2(2x + 2) i.e. 4x + 4
Also the total is 42 buttons
So, the equation is
x + 2x + 2x + 2 + 4x + 4 = 42

Maria solved the equation -5n = -9. Her answer was n = 1. She is fairly confident about her answer, but wants to do a quick check of her solution using estimation.
The solution to an equation is the true value of the equation
So, Maria's solution is incorrect
The equation is given as:
[tex]-5n = -9[/tex]
And the solution is given as:
[tex]n = 1[/tex]
To determine if her solution is correct, then she needs to substitute her solution in the given equation.
In other words, substitute 1 for n in [tex]-5n = -9[/tex]
[tex]-5 \times 1 = -9[/tex]
Multiply -5 and 1
[tex]-5 = -9[/tex]
The above equation is false.
This is so, because -5 does not equal -9
i,e, [tex]-5 \ne -9[/tex]
Hence, Maria's solution is incorrect

If you toss a coin and spin the spinner, what is the probability of landing on heads and spinning blue?
Answer:
Step-by-step explanation:
There are two sides on a coin, heads and tails. So, the probability of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.
The required probability of landing on heads and spinning blue is 3/4.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
There are two sides to a coin, heads, and tails.
So, the probability of flipping heads is going to be half, as there is one option out of the two options that you will flip a head.
As for spinning blue, there are three choices that are blue out of the four color options given.
So, the required probability = favorable outcomes / total outcomes
So, the required probability = 3/4
Hence, the probability of spinning blue would be 3/4.

Explanation:
The value of k determines the slope, or rate of change, of how fast the balloon is climbing per second.
For example, if k = 5, then that means the balloon is going upward at 5 feet per second (equivalent to roughly 3.41 mph)
If k = 5, then y = kt becomes y = 5t. Note how we have the following
t = 0 leads to y = 0t = 1 leads to y = 5t = 2 leads to y = 10t = 3 leads to y = 15and so on. Each time t goes up by 1, d goes up by 5. This is one way to see how the speed is 5/1 = 5 ft per second.
