Answer:the slope is 20
Step-by-step explanation:
Answer:
m=20
Step-by-step explanation:
The line is in point slope form, or
y=mx+b
where m is the slope and b is the y-intercept
For the equation
y=20x
20 and x are being multiplied. The number being multiplied by x is the slope, therefore the slope is 20
Solve for x:
-0.6x > 3
A. X < -5
B X < -0.2
C X > -5
D. X > -0.2
I don’t need an explanation just the answer thank you
Answer:
A
Step-by-step explanation:
Given
- 0.6x > 3
Divide both sides by - 0.6, reversing the symbol as a result of dividing by a negative quantity, thus
x < - 5 → A
An angle measuring 32 degrees has a complement that measures ( 2x-16 ) degrees. What is the value
Answer:
x=37
Step-by-step explanation:
Complementary angles add up to 90 degrees.
Let's first find the measure of the complement.
90-32=58
Now we can set the numerical value of it equal to the expression it gave us.
2x-16=58
We have to isolate x.
Lets add 16 to both sides
2x=74
Divide both sides by 2.
x=37

A 48-inch board is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is ______
inches long.
Answer:
12 inches long
Step-by-step explanation:
So you have the ratio x : 3x
4x = 48
x = 12
Plug in:
12 * 1 = 12
The length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A 48-inch board is cut into two pieces. One piece is three times the length of the other.
Let x and y be the length.
x = 3y
x + y = 48
3y + y = 48
y = 12 inches
x = 36 inches
Thus, the length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.

You flip a coin and then roll a fair six-sided die. The coin lands heads-up and the die shows an even number.
please show work thanks!
Answer:
1/4 = 25%
Step-by-step explanation:
The probability of heads is 1/2.
The probability of an even number on a die is 3/6 = 1/2.
The probability of both is (1/2) (1/2) = 1/4, or 25%.
Answer:
make me brainlist pls pls pls pls
Step-by-step explanation:
A "fair" coin lands heads-up half of the time and "tails-up" half of the time.
For one flip, the probability of landing heads-up is 1/2.
Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.
So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.

There are ten kids in a class. When any two meet, they shake their hands.Before the class starts, how many handshakes are there?
Answer: 45 handshakes.
Step-by-step explanation:
We have 10 kids.
Let's count.
Kid 1, can meet other 9 kids, so here we have 9 handshakes.
Kid 2, he can meet other 9 kids, but he already handshaked kid 1, so here we only count 8 handshakes.
Kid 3, he can meet other 9 kids, but we already counted the handshake with kid 1 and kid 2, so from here we only count 7 handshakes.
You can see the pattern, the total number of handshakes will be:
H = 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45
Answer:
45 handshakes

solve similar triangles
Answer:
22.5
Step-by-step explanation:
With similar triangles you don't have to solve for any angle, as both triangles are alike, just different sizes in the case. So 20/12 = 5/3 or 1.66, and the same for 27.5/16.5, so using that, we have 37.5/1.66 which is 22.5

Use conversions to solve the problem. Jane wants to edge her garden with stone. All sides are equal. The stone costs $6 per yard. What is the perimeter of the garden? How much will it cost to buy the edging she needs?
Answer:
Perimeter: [tex]p = 4\cdot l[/tex], Total costs: [tex]C = 24\cdot l[/tex]
Step-by-step explanation:
The garden has a square form. Let be [tex]l[/tex] the length of any of the sides, measured in yards. The perimeter of the garden, measured in yards, is:
[tex]p = 4\cdot l[/tex]
Now, perimeter has a length unit and total costs of edging the garden, measured in US dollar, is:
[tex]C = \left(6\,\frac{USD}{yard} \right)\cdot 4\cdot l[/tex]
[tex]C = 24\cdot l[/tex]
